Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Autophagy , or autophagocytosis , is a selective intracellular degradative process involving the cell's own lysosomal apparatus . An essential component in cell development , homeostasis , repair and resistance to stress , autophagy may result in either cell death or survival . The targeted region of the cell is sequestered within a membrane structure , the autophagosome , for regulation of the catabolic process . A key factor in both autophagosome formation and autophagosome maturation is a protein encoded by the ultraviolet irradiation resistance-associated gene ( UVRAG ) . Conversely , the serine/threonine-specific protein kinase B ( PKB , also known as Akt ) , which regulates survival in various cancers , inhibits autophagy through mTOR activation . We found that Akt1 may also directly inhibit autophagy by down-regulating UVRAG both in a 293T transient transfection system and breast cancer cells stably expressing Akt1 . The UVRAG with mutations at putative Akt1-phosphorylation sites were still inhibited by Akt1 , and dominant-negative Akt1 also inhibited UVRAG expression , suggesting that Akt1 down-regulates UVRAG by a kinase activity-independent mechanism . We showed that Akt1 overexpression in MDA-MB-231 breast cancer cells down-regulated UVRAG transcription . Cells over-expressing Akt1 were more resistant than control cells to ultraviolet light-induced autophagy and exhibited the associated reduction in cell viability . Levels of the autophagosome indicator protein LC3B-II and mRFP-GFP-LC3 were reduced in cells that over-expressing Akt1 . Inhibiting Akt1 by siRNA or reintroducing UVRAG gene rescued the level of LC3B-II in UV-irradiation . Altogether , these data suggest that Akt1 may inhibit autophagy by decreasing UVRAG expression , which also sensitizes cancer cells to UV irradiation . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Von Hippel-Lindau ( VHL ) is a tumor suppressor that negatively regulates the production of angiogenic factors . Mutations in the VHL gene cause VHL syndrome , which is characterized by highly vascularized tumors . Here we report a c.464T>A mutation of the VHL gene in three patients with hemangioblastoma from a Chinese family . This mutation was not reported previously and was absent in the unaffected family members . The mutation is predicted to cause Val to Glu substitution at VHL protein residue 155 in a conserved region . Previous biochemical studies demonstrated that residue Val-155 was critical for VHL protein binding to chaperonin TRiC/CCT , an essential step for proper VHL protein folding . Our finding of naturally occurring VHL V155E mutation in patients with VHL syndrome supports the functional importance of Val-155 residue in VHL protein and illustrates the diversity of VHL gene defects underlying VHL syndrome .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The β2-adrenergic receptor ( β2AR ) mediates the effects of chronic stress in several neoplasms , however , β2AR signaling is impaired by hypoxia in various tissues . While hypoxia is a common feature significant in the progression of solid tumors , little is known about the effect of hypoxia on β2AR signaling in the tumor microenvironment . Previously , it has been reported that the systemic administration of mesenchymal stem cells ( MSCs ) increased the engraftment and metastatic colonization of rat osteosarcoma ( OS ) cells . In the current study , the effect of MSCs on the hypoxia-induced desensitization of the β2AR in OS cells was investigated . Epinephrine , norepinephrine and isoproterenol increased the cellular proliferation of the rat OS cell line COS1NR and rat MSCs in a dose-dependent and β2AR antagonist-sensitive manner . While isoproterenol had significant proliferative effects on MSCs under normoxic and hypoxic conditions , COS1NR cells did not respond under hypoxic conditions . A sensitivity assay for the β2AR revealed that hypoxia impaired the sensitivity of COS1NR cells , whereas hypoxia did not affect MSCs . An immunoassay revealed no significant change in the expression of hypoxia-inducible factor-1α ( HIF1α ) in COS1NR cells , whilst an immunoassay demonstrated a 15% increase in MSCs following isoproterenol stimulation . In COS1NR cells co-cultured with MSCs under hypoxic conditions , isoproterenol caused a significant increase in proliferation and this effect was inhibited by an anti-interleukin ( IL)-6 antibody . A tumor formation assay in syngeneic rats revealed that the systemic administration of MSCs enhances the growth of OS and the effect of MSCs was inhibited by IL-6 neutralization . In conclusion , MSCs are resistant to the hypoxia-induced desensitization to β2AR . Hypoxia caused a siginificant desensitization of the β2AR in COS1NR cells alone , whereas MSCs may support tumor progression through cellular interactions . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Genomic instability drives tumorigenesis , but how it is initiated in sporadic neoplasias is unknown . In early preneoplasias , alterations at chromosome fragile sites arise due to DNA replication stress . A frequent , perhaps earliest , genetic alteration in preneoplasias is deletion within the fragile FRA3B/FHIT locus , leading to loss of Fhit protein expression . Because common chromosome fragile sites are exquisitely sensitive to replication stress , it has been proposed that their clonal alterations in cancer cells are due to stress sensitivity rather than to a selective advantage imparted by loss of expression of fragile gene products . Here , we show in normal , transformed , and cancer-derived cell lines that Fhit-depletion causes replication stress-induced DNA double-strand breaks . Using DNA combing , we observed a defect in replication fork progression in Fhit-deficient cells that stemmed primarily from fork stalling and collapse . The likely mechanism for the role of Fhit in replication fork progression is through regulation of Thymidine kinase 1 expression and thymidine triphosphate pool levels ; notably , restoration of nucleotide balance rescued DNA replication defects and suppressed DNA breakage in Fhit-deficient cells . Depletion of Fhit did not activate the DNA damage response nor cause cell cycle arrest , allowing continued cell proliferation and ongoing chromosomal instability . This finding was in accord with in vivo studies , as Fhit knockout mouse tissue showed no evidence of cell cycle arrest or senescence yet exhibited numerous somatic DNA copy number aberrations at replication stress-sensitive loci . Furthermore , cells established from Fhit knockout tissue showed rapid immortalization and selection of DNA deletions and amplifications , including amplification of the Mdm2 gene , suggesting that Fhit loss-induced genome instability facilitates transformation . We propose that loss of Fhit expression in precancerous lesions is the first step in the initiation of genomic instability , linking alterations at common fragile sites to the origin of genome instability .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: MicroRNAs ( miRNAs ) are considered to be regulators of various biological processes in cancers , including the epithelial to mesenchymal transition ( EMT ) , which is a key factor in cancer metastasis . In this study , we aimed to clarify the potential roles of miR-490-3p in hepatocellular carcinoma ( HCC ) cells . Using real-time quantitative RT-PCR , we discovered that miR-490-3p was up-regulated in HCC tissues and cells compared with the adjacent non-tumor tissues and normal cells . We also found that overexpression of miR-490-3p led to an increase in cell proliferation , migration , and invasion abilities and that it contributed to EMT . The inhibition of miR-490-3p had the opposite effect on the cells . We identified ERGIC3 ( endoplasmic reticulum-Golgi intermediate compartment protein 3 ) as a direct target gene for miR-490-3p . Unlike most miRNA-mRNA interactions , miR-490-3p increased ERGIC3 mRNA and protein levels as well as the intensity of expression of the EGFP reporter gene controlled by the 3'-UTR of ERGIC3 mRNA . The up-regulation by miR-490-3p also required the participation of Ago2 . The inhibition of miR-490-3p reduced the expression of ERGIC3 . Overexpression of ERGIC3 led to the same effect on HCC cells as miR-490-3p overexpression , including EMT . Importantly , silencing ERGIC3 reversed the cellular responses mediated by miR-490-3p overexpression . In conclusion , our study indicated for the first time that miR-490-3p functioned like an oncogenic miRNA in HCC cells and that the inhibition of miR-490-3p might provide an potential treatment approach for HCC patients .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Group VIB Phospholipase A(2) ( iPLA(2)γ ) is distributed in membranous organelles in which β-oxidation occurs , that is , mitochondria and peroxisomes , and is expressed by insulin-secreting pancreatic islet β-cells and INS-1 insulinoma cells , which can be injured by inflammatory cytokines , for example , IL-1β and IFN-γ , and by oxidants , for example , streptozotocin ( STZ ) or t-butyl-hydroperoxide ( TBHP ) , via processes pertinent to mechanisms of β-cell loss in types 1 and 2 diabetes mellitus . We find that incubating INS-1 cells with IL-1β and IFN-γ , with STZ , or with TBHP causes increased expression of iPLA(2)γ mRNA and protein . We prepared INS-1 knockdown ( KD ) cell lines with reduced iPLA(2)γ expression , and they proliferate more slowly than control INS-1 cells and undergo increased membrane peroxidation in response to cytokines or oxidants . Accumulation of oxidized phospholipid molecular species in STZ-treated INS-1 cells was demonstrated by LC/MS/MS scanning , and the levels in iPLA(2)γ-KD cells exceeded those in control cells. iPLA(2)γ-KD INS-1 cells also exhibited higher levels of apoptosis than control cells when incubated with STZ or with IL-1β and IFN-γ . These findings suggest that iPLA(2)γ promotes β-cell proliferation and that its expression is increased during inflammation or oxidative stress as a mechanism to mitigate membrane injury that may enhance β-cell survival .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The functions of Rap-1A in oral carcinogenesis are largely unexplored . In this study , we examined the expression of Rap-1A at different malignant stages of oral cavity squamous cell carcinoma ( OCSCC ) . Semiquantitative RT-PCR , quantitative RT-PCR , and Western blotting were used to evaluate Rap-1A mRNA and protein expressions , respectively , in paired OCSCC patient specimens . To determine the possible correlation between Rap-1A expression and various clinical characteristics , 256 samples from patients with OCSCC were evaluated by immunohistochemical staining . Strong Rap-1A expression was a significant prognostic marker and predictor of aggressive OCSCC . The overall and disease-specific 5-year survival rates were significantly correlated with strong expression of Rap-1A ( P &lt ; 0.001 ) . Functionally , overexpressed Rap-1A could promote oral cancer cell migration and invasion by Transwell chambers and wound healing assay . Conversely , the suppression of Rap-1A expression using Rap-1A-mediated siRNA was sufficient to decrease cell motility . Furthermore , our data also illustrated that Aurora-A could not only induce mRNA and protein expressions of Rap-1A for enhancing cancer cell motility but also co-localize and form a complex with Rap-1A in the oral cancer cell line . Finally , immunohistochemical staining , indirect immunofluorescence , and Western blotting analysis of human aggressive OCSCC specimens revealed a significantly positive correlation between Rap-1A and Aurora-A expression . Taken together , our results suggest that the Aurora-A/Rap-1A pathway is associated with survival , tumor progression , and metastasis of OCSCC patients . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Methyleugenol ( MEG ) , a constituent of plants used in the human diet , is hepatocarcinogenic in rodents . In an experiment to elucidate its mode of action in rat liver , male F344 rats were administered MEG intragastrically at 3 doses per week for up to 16 weeks in an initiation phase , after which half the rats were fed 500 ppm phenobarbital ( PB ) in the diet to promote liver neoplasia and the other half were maintained on control diet for 24 weeks . At 8 and 16 week interim terminations , ( 32)P-nucleotide postlabeling assay revealed 3 adducts in livers of all MEG groups . The hepatocellular replicating fractions , measured by proliferating cell nuclear antigen immunohistochemistry , were doubled or more in all MEG groups . Hepatocellular altered foci , detected by glutathione S-transferase-placental type ( π ) immunohistochemistry , were present beginning with the high dose group at 8 weeks and extending to all MEG groups at 16 weeks . At the end of maintenance/promotion phase , the incidences , multiplicity and size of foci was similar between control and low dose groups , while those of mid and high dose groups were increased . Hepatocellular adenomas occurred in the mid and high dose groups , attaining higher multiplicity and size with PB . Thus , MEG had rapid initiating activity , reflecting the formation of DNA adducts and possibly cell proliferation . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The potential of cytologically reconstructed barley line D-2946 to cope with the major lesions that hamper genome integrity , namely DNA single- and double-strand breaks was investigated . Strand breaks induced by γ-rays and Li ions were assessed by neutral and alkaline comet assay . Repair capacity after bleomycin treatment was evaluated by agarose gel electrophoresis under neutral and alkaline conditions . Frequencies of radiation-induced chromosome aberrations were also determined . Results indicate that radiation-mediated constitutive rearrangement of the chromosome complement has led to a substantial modulation of the sensitivity of barley genome towards DNA strand breaks , produced by ionising radiation , Li ion implantation and bleomycin in an agent-specific manner , as well as of the clastogenic response to γ-rays . Based on these findings , reconstructed barley karyotype D-2946 can be considered a candidate radio-sensitive line with reduced ability to maintain genome integrity with respect to both DNA and chromosomal damage .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Tumor-infiltrating immune cells can promote chemoresistance and metastatic spread in aggressive tumors . Consequently , the type and quality of immune responses present in the neoplastic stroma are highly predictive of patient outcome in several cancer types . In addition to host immune responses , intrinsic tumor cell activities that mimic stem cell properties have been linked to chemoresistance , metastatic dissemination and the induction of immune suppression . Cancer stem cells are far from a static cell population ; rather , their presence appears to be controlled by highly dynamic processes that are dependent on cues from the tumor stroma . However , the impact immune responses have on tumor stem cell differentiation or expansion is not well understood . In this study , we demonstrate that targeting tumor-infiltrating macrophages and inflammatory monocytes by inhibiting either the myeloid cell receptors CSF1R or CCR2 decreases the number of tumor-initiating cells in pancreatic tumors . Targeting CCR2 or CSF1R improves chemotherapeutic efficacy , inhibits metastasis and increases antitumor T-cell responses . Tumor-educated macrophages also directly enhanced the tumor-initiating capacity of pancreatic tumor cells by activating the transcription factor STAT3 , thereby facilitating macrophage-mediated suppression of CD8+ T lymphocytes . Together , our findings show how targeting tumor-infiltrating macrophages can effectively overcome therapeutic resistance mediated by tumor-initiating cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The glutathione peroxidases , a family of selenocysteine-containing redox enzymes , play pivotal roles in balancing the signaling , immunomodulatory , and deleterious effects of reactive oxygen species ( ROS ) . The glutathione peroxidase GPX3 is the only extracellular member of this family , suggesting it may defend cells against ROS in the extracellular environment . Notably , GPX3 hypermethylation and underexpression occur commonly in prostate , gastric , cervical , thyroid , and colon cancers . We took a reverse genetics approach to investigate whether GPX3 would augment inflammatory colonic tumorigenesis , a process characterized by oxidative stress and inflammation , comparing Gpx3(-/-) mice in an established two-stage model of inflammatory colon carcinogenesis . Gpx3-deficient mice exhibited an increased tumor number , though not size , along with a higher degree of dysplasia . In addition , they exhibited increased inflammation with redistribution toward protumorigenic M2 macrophage subsets , increased proliferation , hyperactive WNT signaling , and increased DNA damage . To determine the impact of acute gene loss in an established colon cancer line , we silenced GPX3 in human Caco2 cells , resulting in increased ROS production , DNA damage and apoptosis in response to oxidative stress , combined with decreased contact-independent growth . Taken together , our results suggested an immunomodulatory role for GPX3 that limits the development of colitis-associated carcinoma . OUTPUT:

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Low-dose cyclophosphamide ( CP ) therapy induces immunogenic tumor cell death and decreases regulatory T cell ( Treg ) numbers in mice with transplantable tumors . Using the ret transgenic murine melanoma model that resembles human melanoma , we detected no beneficial antitumor effects with such treatment , despite a decrease in Tregs . On the contrary , low-dose CP enhanced the production of chronic inflammatory mediators in melanoma lesions associated with increased accumulation of Gr1(+)CD11b(+) myeloid-derived suppressor cells ( MDSCs ) , which exhibit elevated suppressive activity and nitric oxide ( NO ) production as well as inhibition of T-cell proliferation . Moreover , the frequencies of CD8(+) T cells in the tumors and their ability to produce perforin were decreased . To study whether the observed CP-induced MDSC expansion and activation also occurs under chronic inflammatory tumor-free conditions , mice exhibiting chronic inflammation were treated with CP . Similar to tumor-bearing mice , CP-treated inflamed mice displayed elevated levels of MDSCs with enhanced production of NO , reactive oxygen species , and a suppressed in vivo natural killer ( NK ) cell cytotoxic activity indicating CP effects on the host immune system independent of the tumor . We suggest that melanoma therapy with low-dose CP could be efficient only when combined with the neutralization of MDSC immunosuppressive function and chronic inflammatory microenvironment.Journal of Investigative Dermatology advance online publication , 6 December 2012 ; doi:10.1038/jid.2012.444 .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: BACKGROUND Young age is a favorable prognostic factor for patients with glioblastoma multiforme ( GBM ) . We reviewed the outcomes and molecular tumor characteristics of adolescent and young adult patients with GBM treated in 2 Austrian centers . PATIENTS AND METHODS Data on patients with histologically proven primary GBM diagnosed from 18 through 40 years of age were retrospectively analyzed . All patients were treated with standard first-line therapy . The primary end points were overall survival ( OS ) and time to progression ( TTP ) . IDH1-R132H mutation status was analyzed using immunohistochemistry , and MGMT promoter methylation was assessed using methylation-specific polymerase chain reaction . RESULTS We included 70 patients ( 36 men and 34 women ) with a median age of 33 years . IDH1-R132H mutations were detected in 22 ( 39.3% ) of 56 cases and MGMT promoter methylation in 33 ( 61.1% ) of 54 cases with available tissue samples . In patients with wild-type IDH , median TTP was 8.2 months and median OS was 24 months , compared with 18 months and 44 months , respectively , observed in patients with mutated IDH . Neither IDH1 nor MGMT status showed a statistically significant association with TTP or OS . Of note , the social and economical situation of the young patients with GBM was alarming , because only 17% succeeded in staying employed after receiving the diagnosis . CONCLUSIONS We found a high frequency of IDH1 mutations and MGMT promoter methylation among young adult patients with primary GBM that may contribute to the generally favorable outcome associated with young age . The social and economic coverage of patients with glioma remains an unsolved socio-ethical problem . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Kinins and their receptors have been recently implicated in cancer . Using functional and molecular approaches , we investigated the relevance of kinin B(1) and B(2) receptors in bladder cancer . Functional studies were conducted using bladder cancer cell lines , and human biopsies were employed for molecular studies . Both B(1) des-Arg(9)-BK and B(2) BK receptor agonists stimulated the proliferation of grade 3-derived T24 bladder cancer cells . Furthermore , treatment with B(1) and B(2) receptor antagonists ( SSR240612 and HOE140 ) markedly inhibited the proliferation of T24 cells . Only higher concentrations of BK increased the proliferation of the grade 1 bladder cancer cell line RT4 , while des-Arg(9)-BK completely failed to induce its proliferation . Real-time PCR revealed that the mRNA expression of kinin receptors , particularly B(1) receptors , was increased in T24 cells relative to RT4 cells . Data from bladder cancer human biopsies revealed that B(1) receptor expression was increased in all tumor samples and under conditions of chronic inflammation . We also show novel evidence demonstrating that the pharmacological inhibition of PI3Kγ ( phosphatidylinositol 3-kinase ) with AS252424 , concentration-dependently reduced T24 cell proliferation induced by BK or des-Arg(9)-BK . Finally , the incubation of T24 cells with kinin agonists led to a marked activation of the PI3K/AKT and ERK 1/2 signaling pathways , whereas p38 MAP kinase remained unaffected . Kinin receptors , especially B(1) receptors , appear to be implicated in bladder cancer progression . It is tempting to suggest that selective kinin antagonists might represent potential alternative therapies for bladder cancer . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Osteosarcoma is a high-grade malignant bone tumor that manifests ingravescent clinical behavior . The intrinsic events that confer malignant properties on osteosarcoma cells have remained unclear , however . We previously established two lines of mouse osteosarcoma cells : AX cells , which are able to form tumors in syngeneic mice , and AXT cells , which were derived from such tumors and acquired an increased tumorigenic capacity during tumor development . We have now identified Igf2 mRNA-binding protein3 ( Imp3 ) as a key molecule responsible for this increased tumorigenicity of AXT cells in vivo . Imp3 is consistently up-regulated in tumors formed by AX cells , and its expression in these cells was found to confer malignant properties such as anchorage-independent growth , loss of contact inhibition , and escape from anoikis in vitro . The expression level of Imp3 also appeared directly related to tumorigenic ability in vivo which is the critical determination for tumor-initiating cells . The effect of Imp3 on tumorigenicity of osteosarcoma cells did not appear to be mediated through Igf2-dependent mechanism . Our results implicate Imp3 as a key regulator of stem-like tumorigenic characteristics in osteosarcoma cells and as a potential therapeutic target for this malignancy . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Oxaliplatin is included in a number of effective combination regimens used as first and subsequent lines of therapy for metastatic colorectal cancer . Accumulating evidence indicates that autophagy plays a significant role in response to cancer therapy . However , the role of autophagy in oxaliplatin-induced cell death remains to be clarified . In this study , we showed that oxaliplatin induced cell death and autophagy in Caco-2 colorectal cancer cells . The suppression of autophagy using either pharmacologic inhibitors ( 3-methyladenine , bafilomycin A1 ) or RNA interference in essential autophagy genes ( ATG5 or Beclin1 ) enhanced the cell death and reactive oxygen species ( ROS ) production induced by oxaliplatin in Caco-2 cells . Blocking oxaliplatin-induced ROS production by using ROS scavengers ( NAC or Tiron ) decreased autophagy . Furthermore , numerous dilated endoplasmic reticula ( ER ) were present in oxaliplatin-treated Caco-2 cells , and blocking ER stress by RNA interference against candidate of metastasis-1 ( P8 ) and C/EBP-homologous protein ( CHOP ) decreased autophagy and ROS production . Taken together , these data indicate that oxaliplatin activates autophagy as a cytoprotective response via ER stress and ROS in human colorectal cancer cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Lymphocytes are a key component of the immune system and their differentiation and function are directly influenced by cancer . We examined peripheral blood lymphocyte ( PBL ) gene expression as a biomarker of illness and treatment effect using the Affymetrix Human Gene ST1 platform in patients with metastatic renal cell carcinoma ( mRCC ) who received combined treatment with IL-2 , interferon-?-2a and dendritic cell vaccine . We examined gene expression , cytokine levels in patient serum and lymphocyte subsets as determined by flow cytometry ( FCM ) . Pre-treatment PBLs from patients with mRCC exhibit a gene expression profile and serum cytokine profile consistent with inflammation and proliferation not found in healthy donors ( HD ) . PBL gene expression from patients with mRCC showed increased mRNA of genes involved with T-cell and T(REG)-cell activation pathways , which was also reflected in lymphocyte subset distribution . Overall , PBL gene expression post-treatment ( POST ) was not significantly different than pre-treatment ( PRE ) . Nevertheless , treatment related changes in gene expression ( post-treatment minus pre-treatment ) revealed an increased expression of T-cell and B-cell receptor signaling pathways in responding ( R ) patients compared to non-responding ( NR ) patients . In addition , we observed down-regulation of T(REG)-cell pathways post-treatment in R vs. NR patients . While exploratory in nature , this study supports the hypothesis that enhanced inflammatory cytotoxic pathways coupled with blunting of the regulatory pathways is necessary for effective anti-cancer activity associated with immune therapy . This type of analysis can potentially identify additional immune therapeutic targets in patients with mRCC . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Metastasis , commonly to the lung , is the major cause of mortality from testicular cancer . The aim of the present study was to examine the effect of a novel nutrient mixture ( NM ) containing ascorbic acid , amino acids and green tea extract on the inhibition of melanoma growth and metastasis using a model of intratesticular inoculation of B16FO cells into nude mice . Male athymic mice ( n=12 ) , 10-12 weeks of age , were inoculated with 5�10(5) B16FO melanoma cells in 100 μl of PBS into the right testis , while the left testis was left untreated . Following inoculation , the mice were randomly divided into two groups . The control group ( n=6 ) was fed a regular mouse chow diet and the NM 1% group ( n=6 ) the same diet , but supplemented with 1% NM . Four weeks later the mice were sacrificed and the abdominal cavity was opened . Mice in the control group exhibited extensive metastasis in the peritoneal cavity and severely enlarged right testes and necrotic seminiferous tubules . By contrast , in the NM 1% fed group there was no evidence of peritoneal metastasis in 50% of the animals and mild metastasis in the remaining 50% . The right testes were enlarged and seminiferous tubules in the area of invasion showed evidence of degeneration . No metastasis to the liver , kidney or spleen were evident in either group . However , severe lung metastasis was observed in 2 of 6 mice in the control group and mild metastasis in 2 of 6 mice in the NM 1% group . In conclusion , these results confirm earlier studies and verify the anti-metastatic potential of NM . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The prediction of tumor behavior for patients with oral carcinomas remains a challenge for clinicians . The presence of lymph node metastasis is the most important prognostic factor but it is limited in predicting local relapse or survival . This highlights the need for identifying biomarkers that may effectively contribute to prediction of recurrence and tumor spread . In this study , we used one- and two-dimensional gel electrophoresis , mass spectrometry and immunodetection methods to analyze protein expression in oral squamous cell carcinomas . Using a refinement for classifying oral carcinomas in regard to prognosis , we analyzed small but lymph node metastasis-positive versus large , lymph node metastasis-negative tumors in order to contribute to the molecular characterization of subgroups with risk of dissemination . Specific protein patterns favoring metastasis were observed in the " more-aggressive " group defined by the present study . This group displayed upregulation of proteins involved in migration , adhesion , angiogenesis , cell cycle regulation , anti-apoptosis and epithelial to mesenchymal transition , whereas the " less-aggressive " group was engaged in keratinocyte differentiation , epidermis development , inflammation and immune response . Besides the identification of several proteins not yet described as deregulated in oral carcinomas , the present study demonstrated for the first time the role of cofilin-1 in modulating cell invasion in oral carcinomas .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Topoisomerase 1 ( Top1)-DNA cleavage complexes induced by camptothecin ( CPT ) cause DNA strand breaks during DNA replication or transcription . Although the cellular responses to replication-mediated DNA double-strand breaks have been well studied , the responses to transcription-mediated DNA strand breaks have not . Here , we show that poly ( ADP-ribose ) polymerase ( PARP ) and cockayne syndrome group B protein ( CSB ) modulate the CPT-induced formation of discrete p53-binding protein 1 ( 53BP1 ) nuclear foci at sites of transcription-mediated DNA strand breaks . Inhibition of PARP activity enhanced the formation of these foci , while knockdown of essential components of the base excision repair ( BER ) pathway did not . These findings suggest that PARP suppresses transcription-mediated 53BP1 foci formation , but that this does not occur through the BER pathway . In addition , knockdown of CSB , one of the key factors of transcription-coupled repair , slowed the kinetics of 53BP1 foci formation . These data suggest that PARP and CSB modulate the formation of 53BP1 foci during the processing of transcription-mediated DNA strand breaks . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Autophagy is an evolutionarily conserved , multi-step lysosomal degradation process in which a cell degrades its own long-lived proteins and damaged organelles . Ataxia telangiectasia mutated ( ATM ) has recently been shown to upregulate the process of autophagy . Previous studies showed that certain microRNAs , including miR-18a , potentially regulate ATM in cancer cells . However , the mechanisms behind the modulation of ATM by miR-18a remain to be elucidated in colon cancer cells . In the present study , we explored the impact of miR-18a on the autophagy process and ATM expression in HCT116 colon cancer cells . To determine whether a preliminary link exists between autophagy and miR-18a , HCT116 cells were irradiated and quantitative ( q ) PCR was performed to measure miR-18a expression . HCT116 cells were transfected with an miR-18a mimic to study its impact on indicators of autophagy . Western blotting and luciferase assays were implemented to explore the impact of miR-18a on ATM gene expression in HCT116 cells . The results showed that miR-18a expression was strongly stimulated by radiation . Ectopic overexpression of miR-18a in HCT116 cell lines potently enhanced autophagy and ionizing radiation-induced autophagy . Moreover , miR-18a overexpression led to the upregulation of ATM expression and suppression of mTORC1 activity . Results of the present study pertaining to the role of miR-18a in regulating autophagy and ATM gene expression in colon cancer cells revealed a novel function for miR-18a in a critical cellular event and on a crucial gene with significant impacts in cancer development , progression , treatment and in other diseases .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: SCOPE Glyceollins are a novel class of soybean phytoalexins with potential cancer-preventive and antiestrogenic effects . The angiogenic cascade during tumor development consists of the release of angiogenic factors and binding of angiogenic factors to receptors on endothelial cells to activate downstream signaling pathways . However , the potential medicinal value of glyceollins , especially in antiangiogenesis , remains unexplored . METHODS AND RESULTS Here , we investigated the antiangiogenic activity of glyceollins and their underlying mechanisms . Glyceollins inhibited vascular endothelial growth factor ( VEGF ) or basic fibroblast growth factor ( bFGF ) induced in vitro angiogenic activity . Glyceollins inhibited VEGF receptor-2 or FGF receptor-1 activity and their downstream signaling pathways such as extracellular regulated kinase 1/2 , c-Jun N-terminal kinase , as well as p38 mitogen-activated protein kinase and focal adhesion kinase induced by VEGF or bFGF . Glyceollins significantly suppressed VEGF receptor-2 kinase activity assayed by the ELISA . Glyceollins significantly attenuated in vivo and ex vivo microvessel development in a dose-dependent manner and tumor growth by suppressing microvessel density in Lewis lung carcinoma ( LLC ) mouse xenograft . CONCLUSION Thus , glyceollins , elicited ingredients of soy source , target the signaling pathways mediated by VEGF or bFGF , providing new perspectives into potential therapeutics for preventing and treating hypervascularized diseases including cancer .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The tumor suppressors Lats1 and Lats2 are mediators of the Hippo pathway that regulates tissue growth and proliferation . Their N-terminal non-kinase regions are distinct except for Lats conserved domains 1 and 2 ( LCD1 and LCD2 ) , which may be important for Lats1/2-specific functions . Lats1 knockout mice were generated by disrupting the N-terminal region containing LCD1 ( Lats1(ΔN/ΔN) ) . Some Lats1(ΔN/ΔN) mice were born safely and grew normally . However , mouse embryonic fibroblasts ( MEFs ) from Lats1(ΔN/ΔN) mice displayed mitotic defects , centrosomal overduplication , chromosomal misalignment , multipolar spindle formation , chromosomal bridging and cytokinesis failure . They also showed anchorage-independent growth and continued cell cycles and cell growth , bypassing cell-cell contact inhibition similar to tumor cells . Lats1(ΔN/ΔN) MEFs produced tumors in nude mice after subcutaneous injection , although the tumor growth rate was much slower than that of ordinary cancer cells . Yap , a key transcriptional coactivator of the Hippo pathway , was overexpressed and stably retained in Lats1(ΔN/ΔN) MEFs in a cell density independent manner , and Lats2 mRNA expression was downregulated . In conclusion , N-terminally truncated Lats1 induced Lats2 downregulation and Yap protein accumulation , leading to chromosomal instability and tumorigenesis . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Bigelovin is a sesquiterpene lactone isolated from the plant Inula helianthus-aquatica which was traditionally used in cancer treatment in Yunnan , China . The potent apoptotic activities of bigelovin in human leukemia U937 cells were shown in our previous study . The present study investigated the anti-angiogenic and immunomodulatory effects of bigelovin using transgenic zebrafish Tg(fli1a:EGFP)y1 with fluorescent blood vessels and human peripheral blood mononuclear cells ( PBMCs ) , respectively . Furthermore , the inhibitory activities of bigelovin on the human endothelial cell adhesion molecules ( CAMs ) were also examined . Our results showed that the growth of subintestinal vessels of the bigelovin-treated zebrafish embryos was significantly inhibited and the gene expressions in angiogenesis signaling pathways ( e.g . Ang2 and Tie2 ) of the zebrafish were down-regulated after bigelovin treatment . Besides , the proliferation and Th1 cytokines productions ( e.g . IFN-γ , IL-2 and IL-12 ) were suppressed in bigelovin-treated PBMCs . On the other hand , bigelovin was shown to significantly inhibit the human monocyte adhesion to human endothelial cells and the gene expressions of inflammation-related CAMs ( e.g . ICAM-1 , VCAM-1 and E-selectin ) were significantly down-regulated in bigelovin-treated human endothelial cells . In summary , our data provide the first evidence that bigelovin possesses anti-angiogenic and immunomodulatory activities , suggesting bigelovin may exert multi-target functions against cancer in animal models .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Adipose tissue growth and development are thought to be associated with angiogenesis and extracellular matrix remodeling . Because ginseng has been shown to inhibit angiogenesis and matrix metalloproteinase ( MMP ) activity , we hypothesized that adipose tissue growth and obesity can be regulated by Korean ginseng ( Panax ginseng C.A. Meyer ) . Wild-type C57BL/6J mice were fed for 8 weeks with a low fat diet , a high fat diet ( HFD ) , or HFD supplemented with 0.5% or 5% Korean red ginseng extract . We measured body weight , adipose tissue mass , food intake , MMP activity , and the expression of genes involved in angiogenesis and MMPs . Administering ginseng to HFD-induced obese mice produced reductions in body weight and adipose tissue mass compared with untreated counterparts . Ginseng treatment decreased blood vessel density and MMP activity in adipose tissues . Ginseng also reduced mRNA levels of angiogenic factors ( e.g. , VEGF-A and FGF-2 ) and MMPs ( e.g. , MMP-2 and MMP-9 ) , whereas it increased mRNA levels of angiogenic inhibitors ( e.g. , TSP-1 , TIMP-1 , and TIMP-2 ) in adipose tissues . These results demonstrate that ginseng effectively reduces adipose tissue mass and prevents obesity in diet-induced obese mice and that this process may be mediated in part through the anti-angiogenic actions of ginseng .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: It is well known that ErbB2 , a receptor tyrosine kinase , localizes to the plasma membrane . Here we describe a novel observation that ErbB2 also localizes in mitochondria of cancer cells and patient samples . We found that ErbB2 translocates into mitochondria through association with mtHSP70 . Additionally , mitochondrial ErbB2 ( mtErbB2 ) negatively regulates mitochondrial respiratory functions . Oxygen consumption and activities of complexes of the mitochondrial electron transport chain were decreased in mtErbB2-overexpressing cells . Mitochondrial membrane potential and cellular ATP levels were also decreased . In contrast , mtErbB2 enhanced cellular glycolysis . The translocation of ErbB2 and its impact on mitochondrial function are kinase dependent . Interestingly , cancer cells with higher levels of mtErbB2 were more resistant to the ErbB2-targeting antibody trastuzumab . Our study provides a novel perspective on the metabolic regulatory function of ErbB2 and reveals that mtErbB2 has an important role in the regulation of cellular metabolism and cancer cell resistance to therapeutics .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Vascular integrity is fundamental to the formation of mature blood vessels and depends on a functional , quiescent endothelial monolayer . However , how endothelial cells enter and maintain quiescence in the presence of angiogenic factors is still poorly understood . Here we identify the fibroblast growth factor ( FGF ) antagonist Sprouty2 ( Spry2 ) as a key player in mediating endothelial quiescence and barrier integrity in mouse aortic endothelial cells ( MAECs ) : Spry2 knockout MAECs show spindle-like shapes and are incapable of forming a functional , impermeable endothelial monolayer in the presence of FGF2 . Whereas dense wild type cells exhibit contact inhibition and stop to proliferate , Spry2 knockout MAECs remain responsive to FGF2 and continue to proliferate even at high cell densities . Importantly , the anti-proliferative effect of Spry2 is absent in sparsely plated cells . This cell density-dependent Spry2 function correlates with highly increased Spry2 expression in confluent wild type MAECs . Spry2 protein expression is barely detectable in single cells but steadily increases in cells growing to high cell densities , with hypoxia being one contributing factor . At confluence , Spry2 expression correlates with intact cell-cell contacts , whereas disruption of cell-cell contacts by EGTA , TNFα and thrombin decreases Spry2 protein expression . In confluent cells , high Spry2 levels correlate with decreased extracellular signal-regulated kinase 1/2 ( Erk1/2 ) phosphorylation . In contrast , dense Spry2 knockout MAECs exhibit enhanced signaling by Erk1/2 . Moreover , inhibiting Erk1/2 activity in Spry2 knockout cells restores wild type cobblestone monolayer morphology . This study thus reveals a novel Spry2 function , which mediates endothelial contact inhibition and barrier integrity . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Pancreatic ductal adenocarcinoma ( PDAC ) is one of the most aggressive human neoplasms with extremely poor prognosis and a low survival rate . Immunosuppressive cell populations , e.g. regulatory T cells ( Treg ) , appear to be important in PDAC , contributing to patient's poor prognosis . Therefore , we investigated the PDAC microenvironment with a focus on conventional and regulatory T cells in view of their potential therapeutic importance . We found that tumors from the murine Panc02 orthotopic model of PDAC were infiltrated with high numbers of Treg . Remarkably , these cells exhibited the effector/memory phenotype , suggesting their enhanced suppressive activity and higher proliferation capacity . Although we observed a steady increase in transforming growth factor-β ( TGF-β ) levels in the tumors , treatment with a specific inhibitor of TGF-β receptor I kinase failed to abrogate Treg accumulation . A CCR4 antagonist did not affect Treg percentage in the tumor either . However , intense Treg cell division in the tumor microenvironment was demonstrated , suggesting local proliferation as a major mechanism of Treg accumulation in PDAC . Notably , this accumulation was reduced by low-dose gemcitabine administration , resulting in a modestly increased survival of PDAC mice . Our results provide an insight into mechanisms of immunosuppression in PDAC , suggesting an important role for proliferative expansion of effector/memory Treg . Low-dose gemcitabine therapy selectively depletes Treg , providing a basis for new modalities of PDAC therapy . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Liver resection is now widely accepted as a potentially curative treatment for colorectal liver metastasis . However , the efficacy of surgical resection for gastric cancer liver metastasis(GLM)remains unclear . Based on our 18-year experience with 64 patients who underwent curative hepatectomy for GLM , we discuss the indication and efficacy of surgical resection for GLM . From January 1993 to January 2011 , 73 patients underwent hepatectomy for GLM in the Department of Gastroenterological Surgery , Cancer Institute Ariake Hospital(Japanese Foundation for Cancer Research ) , Japan . The actuarial1 - , 3- , and 5-year overall survival rates and 1- , 3- , and 5-year recurrence-free survival rates of those 64 patients who achieved curative resections were 84 , 50 , and 37% , and 42 , 27 , and 27% , respectively . By multivariate analysis , serosal invasion of the primary gastric cancer and larger hepatic tumor(>5 cm in diameter)were found to be independent indicators of poor prognosis . Based on the multivariate analysis results , all patients were divided into three groups no poor prognostic factor(n=38) , one poor prognostic factor(n=24) , and two poor prognostic factors(n=2) . The actuarial overall survival rates of each group were 63 , 36 , and 0% at 3 years , and 53 , 15 , and 0% at 5 years . GLM patients having hepatic tumors with the maximum diameter of <5 cm , and without serosalinvasion of the primary gastric cancer , are the best candidates for hepatectomy . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: BACKGROUND Treatment of head and neck cancer with radiation often results in damage to surrounding normal tissues such as salivary glands . Permanent loss of function in the salivary glands often leads patients to discontinue treatment due to incapacitating side effects . It has previously been shown that IGF-1 suppresses radiation-induced apoptosis and enhances G2/M arrest leading to preservation of salivary gland function . In an effort to recapitulate the effects of IGF-1 , as well as increase the likelihood of translating these findings to the clinic , the small molecule therapeutic Roscovitine , is being tested . Roscovitine is a cyclin-dependent kinase inhibitor that acts to transiently inhibit cell cycle progression and allow for DNA repair in damaged tissues . METHODOLOGY/PRINCIPAL FINDINGS Treatment with Roscovitine prior to irradiation induced a significant increase in the percentage of cells in the G(2)/M phase , as demonstrated by flow cytometry . In contrast , mice treated with radiation exhibit no differences in the percentage of cells in G(2)/M when compared to unirradiated controls . Similar to previous studies utilizing IGF-1 , pretreatment with Roscovitine leads to a significant up-regulation of p21 expression and a significant decrease in the number of PCNA positive cells . Radiation treatment leads to a significant increase in activated caspase-3 positive salivary acinar cells , which is suppressed by pretreatment with Roscovitine . Administration of Roscovitine prior to targeted head and neck irradiation preserves normal tissue function in mouse parotid salivary glands , both acutely and chronically , as measured by salivary output . CONCLUSIONS/SIGNIFICANCE These studies suggest that induction of transient G(2)/M cell cycle arrest by Roscovitine allows for suppression of apoptosis , thus preserving normal salivary function following targeted head and neck irradiation . This could have an important clinical impact by preventing the negative side effects of radiation therapy in surrounding normal tissues . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: TP53 mutations compromising p53 transcriptional function occur in more than 50% of human cancers , including pancreatic adenocarcinoma , and render cancer cells more resistant to conventional therapy . In the last few years , many efforts have been addressed to identify p53-reactivating molecules able to restore the wild-type transcriptionally competent conformation of the mutated proteins . Here , we show that two of these compounds , CP-31398 and RITA , induce cell growth inhibition , apoptosis , and autophagy by activating p53/DNA binding and p53 phosphorylation ( Ser15 ) , without affecting the total p53 amount . These effects occur in both wild-type and mutant p53 pancreatic adenocarcinoma cell lines , whereas they are much less pronounced in normal human primary fibroblasts . Furthermore , CP-31398 and RITA regulate the axis SESN1-2/AMPK/mTOR by inducing AMPK phosphorylation on Thr172 , which has a crucial role in the autophagic response . The protective role of autophagy in cell growth inhibition by CP-31398 and RITA is supported by the finding that the AMPK inhibitor compound C or the autophagy inhibitors chloroquine or 3-methyladenine sensitize both pancreatic adenocarcinoma cell lines to the apoptotic response induced by p53-reactivating molecules . Our results demonstrate for the first time a survival role for autophagy induced by p53-reactivating molecules , supporting the development of an anti-cancer therapy based on autophagy inhibition associated to p53 activation .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Heparanase is a mammalian endoglycosidase that degrades heparan sulfate at the cell surface and in the extracellular matrix . The expression of heparanase was detected in a wide variety of human malignant tumors and closely associated with tumor invasion , metastasis , and angiogenesis . However , the specific roles of heparanase and its mechanisms of regulating the malignant potential of non-small cell lung cancer ( NSCLC ) cells still remain unclear . In the present study , the expression of heparanase was down-regulated in NSCLC cell line by antisense oligodeoxynucleotide . Results showed that down-regulation of heparanase led to significant inhibition of invasive and proliferative potentials of A549 cells in vitro and in vivo . Further research demonstrated that down-regulation of heparanase significantly inhibited the angiogenic potential of A549 cells , which might be the mechanism responsible for the inhibition of A549 cell proliferation in BALB/c nude mice in vivo . These findings demonstrate that heparanase plays essential roles in regulating the invasion , proliferation , and angiogenesis of A549 cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The role of regulatory T cells ( T(regs) ) in human colon cancer ( CC ) remains controversial : high densities of tumor-infiltrating T(regs) can correlate with better or worse clinical outcomes depending on the study . In mouse models of cancer , T(regs) have been reported to suppress inflammation and protect the host , suppress T cells and protect the tumor , or even have direct cancer-promoting attributes . These different effects may result from the presence of different T(reg) subsets . We report the preferential expansion of a T(reg) subset in human CC with potent T cell-suppressive , but compromised anti-inflammatory , properties ; these cells are distinguished from T(regs) present in healthy donors by their coexpression of Foxp3 and RORγt . T(regs) with similar attributes were found to be expanded in mouse models of hereditary polyposis . Indeed , ablation of the RORγt gene in Foxp3(+) cells in polyp-prone mice stabilized T(reg) anti-inflammatory functions , suppressed inflammation , improved polyp-specific immune surveillance , and severely attenuated polyposis . Ablation of interleukin-6 ( IL-6 ) , IL-23 , IL-17 , or tumor necrosis factor-α in polyp-prone mice reduced polyp number but not to the same extent as loss of RORγt . Surprisingly , loss of IL-17A had a dual effect : IL-17A-deficient mice had fewer polyps but continued to have RORγt(+) T(regs) and developed invasive cancer . Thus , we conclude that RORγt has a central role in determining the balance between protective and pathogenic T(regs) in CC and that T(reg) subtype regulates inflammation , potency of immune surveillance , and severity of disease outcome .

Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Νuclear factor-κB ( NF-κB ) and activator protein-1 ( AP-1 ) are major transcription factors that have been associated with breast cancer metastasis by inducing matrix metalloproteinase-9 ( MMP-9 ) expression . In this study , we investigated the inhibitory effects of guggulsterone isomers ( cis or trans ) on 12-O-tetradecanoylpho-bol-13-acetate ( TPA)-induced MMP-9 expression . Cis-guggulsterone inhibited TPA-induced MMP expression by blocking IκB kinase ( IKK)/NF-κB signaling , whereas trans-guggulsterone blocked mitogen-activated protein kinase ( MAPK)/AP-1 signaling . Cis-guggulsterone was more potent than trans-guggulsterone in the inhibition of TPA-induced MMP-9 expression and invasion of MCF-7 cells . Furthermore , we found that the combination of these isomers exerted an additive effect on the inhibition of MCF-7 cell invasion . These results suggest that guggulsterone isomers downregulate MMP-9 expression and tumor cell invasion through the isomer-specific suppression of IKK/NF-κB and MAPK/AP-1 activation . In addition , the suppression of MMP-9 expression correlated well with the inhibition of cell invasion . OUTPUT:

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Calcium ( Ca(2+) ) signals are involved in important checkpoints in cell death pathways and promote both apoptosis and autophagy . However , the relationship between autophagy and apoptosis in response to Ca(2+) level elevation is poorly understood . Here , we provided evidence that the influx of extracellular Ca(2+) triggered by Trichokonin VI ( TK VI ) , an antimicrobial peptide , induced calpain-dependent apoptosis and autophagy in hepatocellular carcinoma ( HCC ) cells . Remarkably , TK VI preferentially induced apoptosis that was associated with calpain-mediated Bax and Atg5 cleavage , which resulted in the collapse of the mitochondrial membrane potential and cytochrome c release . Interestingly , truncated , but not full-length Atg5 , associated with Bcl-xL and promoted the intrinsic pathway . Moreover , TK VI treatment induced reactive oxygen species ( ROS ) accumulation , an effect in which Bak might play a major role . This accumulation of ROS resulted in the subsequent disposal of damaged mitochondria within autophagosomes via Atg5-mediated and mitochondria-selective autophagy . Both the inhibition of calpain activity and Bax deficiency activated a switch that promoted an enhancement of autophagy . The inhibition of both apoptosis and autophagy significantly attenuated the TK VI cytotoxicity , indicating that the two processes had stimulatory effects during TK VI-meditated cell death . These results suggested that calpain , Bak and Atg5 were molecular links between autophagy and apoptosis and revealed novel aspects of the crosstalk between these two processes . The potential of TK VI is proposed as a promising anticancer agent for its well-characterized activity of Ca(2+) agonist and as a possible novel therapeutic strategy that acts on cancer cell mitochondria .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Integrin αvβ3 plays a role in insulin-like growth factor 1 ( IGF1 ) signaling ( integrin-IGF1 receptor ( IGF1R ) cross-talk ) in non-transformed cells in anchorage-dependent conditions . We reported previously that IGF1 directly binds to αvβ3 and induces αvβ3-IGF1-IGF1R ternary complex formation in these conditions . The integrin-binding defective IGF1 mutant ( R36E/R37E ) is defective in inducing ternary complex formation and IGF signaling , whereas it still binds to IGF1R . We studied if IGF1 can induce signaling in anchorage-independent conditions in transformed Chinese hamster ovary cells that express αvβ3 ( β3-CHO ) cells . Here we describe that IGF1 signals were more clearly detectable in anchorage-independent conditions ( polyHEMA-coated plates ) than in anchorage-dependent conditions . This suggests that IGF signaling is masked by signals from cell-matrix interaction in anchorage-dependent conditions . IGF signaling required αvβ3 expression , and R36E/R37E was defective in inducing signals in polyHEMA-coated plates . These results suggest that αvβ3-IGF1 interaction , not αvβ3-extracellular matrix interaction , is essential for IGF signaling . Inhibitors of IGF1R , Src , AKT , and ERK1/2 did not suppress αvβ3-IGF-IGF1R ternary complex formation , suggesting that activation of these kinases are not required for ternary complex formation . Also , mutations of the β3 cytoplasmic tail ( Y747F and Y759F ) that block β3 tyrosine phosphorylation did not affect IGF1R phosphorylation or AKT activation . We propose a model in which IGF1 binding to IGF1R induces recruitment of integrin αvβ3 to the IGF-IGF1R complex and then β3 and IGF1R are phosphorylated . It is likely that αvβ3 should be together with the IGF1-IGF1R complex for triggering IGF signaling . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The ARF locus is frequently inactivated in human cancer . The oncosuppressor ARF has indeed been described as a general sensor for different situation of cellular stress . We have previously demonstrated that ARF deficiency severely impairs inflammatory responses in vitro and in vivo , establishing a role for ARF in the regulation of innate immunity . The aim of the present work was to get further insights into the immune functions of ARF and to evaluate its possible contribution to the polarization of macrophages toward the M1 or M2 phenotype . Our results demonstrate that resting Arf(-/-) macrophages express high levels of Ym1 and Fizz-1 , two typical markers of alternatively-activated macrophages ( M2 ) . Additionally , Arf(-/-) peritoneal macrophages showed an impaired response to lipopolysaccharide ( a classical inducer of M1 polaryzation ) and a reduced production of pro-inflammatory cytokines/chemokines . Moreover , upon stimulation with interleukin-4 ( IL-4 ) , an inducer of the M2 phenotype , well established M2 markers such as Fizz-1 , Ym1 and arginase-1 were upregulated in Arf(-/-) as compared with wild type macrophages . Accordingly , the cytokine and chemokine profile associated with the M2 phenotype was significantly overexpressed in Arf(-/-) macrophages responding to IL-4 . In addition , multiple pro-angiogenic factors such as VEGF and MMP-9 were also increased . In summary , these results indicate that ARF contributes to the polarization and functional plasticity of macrophages . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: ABSTRACT : PurposeAutophagy has attracted attentions as a novel mechanism for tumor development . In this study Human ovarian carcinoma cell line SKOV3 and multidrug-resistant phenotype SKVCR cells were used and the roles of autophagy in radiation-induced cell death were analyzed.Methods and materialsCell viability was examined by colony formation and cell counting kit-8 ( CCK-8 ) assay , 3MA and ZVAD were used to block autophagy and apoptosis , respectively . Quantitative real-time PCR was used to detect mRNA level and Western blot was used to detect protein expression , monodansylcadaverine ( MDC ) staining and flow cytometery were used for autophagy , apoptosis and cell cycle dynamics , respectively . RESULTS : ( 1 ) The radiosensitivity exhibited differently in SKOV3 and SKVCR cells ( SKOV3 : D0=3.37 , SKVCR : D0= 4.18 ) ; compared with SKOV3 the constitutive expression of MAPLC3 in SKVCR was higher , but no change of Caspase-3 and cleaved Caspase-3 . ( 2 ) The ionizing radiation ( IR)- induced apoptosis and autophagy were significant in both cells ( P<0.05 ) ; inhibition of apoptosis with ZVAD showed no impact on survival of SKOV3 and SKVCR cells after radiation , while inhibition of autophagy significantly decreased viability in SKVCR cells , for SKVO3 cells only low level of radiation ( 2 Gy and 4 Gy ) could decrease the viability(P<0.05) . ( 3 ) ZVAD inhibited apoptosis and autophagy in both cells , 3MA inhibit apoptosis in SKOV3 , and promote apoptosis in SKVCR , together with inhibition of autophagy . ( 4 ) G2/M arrest was induced by radiation in both cells ; the accumulation of G2/M was more significant in SKOV3 , 3MA attenuated the radiation-induced S phase delay in SKVCR . CONCLUSION : IR-induced autophagy provides a self-protective mechanism against radiotherapy in SKVCR cells , the use of autophagy inhibitor , 3MA , increases the killing effects of radiation by inhibiting autophagy and radiation- induced S phase delay , also by the increase of apoptosis , which suggests a better therapeutic strategy in drug- resistant SKVCR ovarian cancer cells .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: In normal human cells , oncogene-induced senescence ( OIS ) depends on induction of DNA damage response . Oxidative stress and hyperreplication of genomic DNA have been proposed as major causes of DNA damage in OIS cells . Here , we report that down-regulation of deoxyribonucleoside pools is another endogenous source of DNA damage in normal human fibroblasts ( NHFs ) undergoing HRAS(G12V)-induced senescence . NHF-HRAS(G12V) cells underexpressed thymidylate synthase ( TS ) and ribonucleotide reductase ( RR ) , two enzymes required for the entire de novo deoxyribonucleotide biosynthesis , and possessed low dNTP levels . Chromatin at the promoters of the genes encoding TS and RR was enriched with retinoblastoma tumor suppressor protein and histone H3 tri-methylated at lysine 9 . Importantly , ectopic coexpression of TS and RR or addition of deoxyribonucleosides substantially suppressed DNA damage , senescence-associated phenotypes , and proliferation arrest in two types of NHF-expressing HRAS(G12V) . Reciprocally , short hairpin RNA-mediated suppression of TS and RR caused DNA damage and senescence in NHFs , although less efficiently than HRAS(G12V) . However , overexpression of TS and RR in quiescent NHFs did not overcome proliferation arrest , suggesting that unlike quiescence , OIS requires depletion of dNTP pools and activated DNA replication . Our data identify a previously unknown role of deoxyribonucleotides in regulation of OIS . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: In this study , laboratory experiments were carried out in order to come to a better understanding of the fate of polycyclic aromatic hydrocarbons ( PAHs ) in the marine environment and especially on their bioaccumulation , biotransformation and genotoxic effects in fish . Juveniles of turbot ( Scophthalmus maximus ) were exposed to PAHs through different routes via ( 1 ) a mixture of dissolved PAHs , ( 2 ) a PAH-polluted sediment and ( 3 ) an oil fuel elutriate . Fish were exposed 4 days followed by a 6-day depuration period . In each experiment , PAH concentrations in the seawater of the tanks were analysed regularly by gas chromatography coupled with mass spectrometry . Muscle and liver samples were also analysed for parent PAH levels and PAH bioconcentration factors were calculated . Biotransformation was evaluated by measuring the levels of PAH metabolites in fish bile . Genotoxicity was assessed by the alkaline comet assay . Regardless of exposure route , the parent PAH concentrations in the liver and muscle showed a peak level 1 day after the beginning of the exposure , followed by a decrease up to the background level towards the end of the experiment , except for the exposure to dissolved PAHs for which levels were relatively low throughout the study . As a consequence , no bioaccumulation was observed in fish tissues at the end of the experiment . In contrast , regardless of exposure routes , a rapid production of biliary metabolites was observed throughout the whole exposure experiment . This was especially true for 1-hydroxypyrene , the major metabolite of pyrene . After 6 days of recovery in clean water , a significant decrease in the total metabolite concentrations occurred in bile . Fish exposed through either route displayed a significant increase in DNA strand breaks after 4 days of exposure , and significant correlations were observed between the level of biliary PAH metabolites and the level of DNA lesions in fish erythrocytes . Overall results indicate that exposure to either a mixture of dissolved PAHs , a PAH-contaminated sediment or a dispersed oil fuel elutriate leads to biotransformation and increase in DNA damage in fish . The quantification of PAH metabolites in bile and DNA damage in erythrocytes appear to be suitable for environmental monitoring of marine pollution either in the case of accidental oil spills or sediment contamination .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Cancer vaccines based on human tumor-associated antigens ( TAA ) have been tested in patients with advanced or recurrent cancer , in combination with or following standard therapy . Their immunogenicity and therapeutic efficacy has been difficult to properly evaluate in that setting characterized by multiple highly suppressive effects of the tumor and the standard therapy on the patient's immune system . In animal models of human cancer , vaccines administered in the prophylactic setting are most immunogenic and effectively prevent cancer development and progression . We report results of a clinical study that show that in patients without cancer but with a history of premalignant lesions ( advanced colonic adenomas , precursors to colon cancer ) , a vaccine based on the TAA MUC1 was highly immunogenic in 17 of 39 ( 43.6% ) of vaccinated individuals , eliciting high levels of anti-MUC1 immunoglobulin G ( IgG ) and long-lasting immune memory . Lack of response in 22 of 39 individuals was correlated with high levels of circulating myeloid-derived suppressor cells ( MDSC ) prevaccination . Vaccine-elicited MUC1-specific immune response and immune memory were not associated with significant toxicity . Our study shows that vaccines based on human TAAs are immunogenic and safe and capable of eliciting long-term memory that is important for cancer prevention . We also show that in the premalignant setting , immunosuppressive environment ( e.g. , high levels of MDSC ) might already exist in some individuals , suggesting an even earlier premalignant stage or preselection of nonimmunosuppressed patients for prophylactic vaccination .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Evaluation of immune dysfunction during the tumor-bearing state is a critical issue in combating cancer . In this study , we initially found that IL-6 , one of the cachectic factors , suppressed CD4(+) T cell-mediated immunity through downregulation of MHC class II by enhanced arginase activity of dendritic cells ( DC ) in tumor-bearing mice . We demonstrated that administration of Ab against IL-6R ( anti-IL-6R mAb ) greatly enhanced T cell responses and inhibited the growth of tumor in vivo . We also found that IL-6 upregulated the expression of arginase-1 and arginase activity of DC in vitro . Tumor-infiltrating CD11c(+) DC exhibited upregulated mRNA expression of arginase-1 but reduced expression of MHC class II in parallel with the increase in serum IL-6 levels at the late stage in tumor-bearing hosts . However , the administration of anti-IL-6R mAb into tumor-bearing mice inhibited both the downmodulation of MHC class II and the upregulation of arginase-1 mRNA levels in DC . Furthermore , we noted that N(ω)-hydroxy-L-arginine or L-arginine , an arginase-1 inhibitor , blocked the reduction in MHC class II levels on CD11c(+) DC during the tumor-bearing state . Finally , we demonstrated that the administration of N(ω)-hydroxy-L-arginine at the peritumor site significantly enhanced CD4(+) T cell responses and inhibited tumor growth . Thus , IL-6-mediated arginase activation and the subsequent reduction in MHC class II expression on DC appeared to be critical mechanisms for inducing dysfunction of the immune system in the tumor-bearing state . Blockade of the IL-6-arginase cascade is a promising tool to overcome the dysfunction of antitumor immunity in tumor-bearing hosts . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The ASPP2 ( also known as 53BP2L ) tumor suppressor is a proapoptotic member of a family of p53 binding proteins that functions in part by enhancing p53-dependent apoptosis via its C-terminal p53-binding domain . Mounting evidence also suggests that ASPP2 harbors important nonapoptotic p53-independent functions . Structural studies identify a small G protein Ras-association domain in the ASPP2 N terminus . Because Ras-induced senescence is a barrier to tumor formation in normal cells , we investigated whether ASPP2 could bind Ras and stimulate the protein kinase Raf/MEK/ERK signaling cascade . We now show that ASPP2 binds to Ras-GTP at the plasma membrane and stimulates Ras-induced signaling and pERK1/2 levels via promoting Ras-GTP loading , B-Raf/C-Raf dimerization , and C-Raf phosphorylation . These functions require the ASPP2 N terminus because BBP ( also known as 53BP2S ) , an alternatively spliced ASPP2 isoform lacking the N terminus , was defective in binding Ras-GTP and stimulating Raf/MEK/ERK signaling . Decreased ASPP2 levels attenuated H-RasV12-induced senescence in normal human fibroblasts and neonatal human epidermal keratinocytes . Together , our results reveal a mechanism for ASPP2 tumor suppressor function via direct interaction with Ras-GTP to stimulate Ras-induced senescence in nontransformed human cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: ABSTRACT : BACKGROUND : Chemokine receptor CXCR4 , together with its ligand CXCL12 , plays critical roles in cancer progression , including growth , metastasis and angiogenesis . Ewing sarcoma is a sarcoma with poor prognosis despite current therapies , particularly for patients with advanced-stage disease . Lungs and bone ( marrow ) , organs of predilection for ( primary/metastatic ) Ewing sarcoma , represent predominant CXCL12 sources . METHODS : To gain insight into the role of the CXCR4-CXCL12 axis in Ewing sarcoma , CXCR4 , CXCL12 and hypoxia-inducible factor-1alpha protein expression was studied in therapy-naive and metastatic tumors by immunohistochemistry . CXCR4 function was assessed in vitro , by flow cytometry and proliferation/ cell viability assays , in the presence of recombinant CXCL12 and/or CXCR4-antagonist AMD3100 or under hypoxic conditions . RESULTS : Whereas CXCR4 was predominantly expressed by tumor cells , CXCL12 was observed in both tumor and stromal areas . Survival analysis revealed an ( expression level-dependent ) negative impact of CXCR4 expression ( p &lt ; 0.04 ) . A role for the CXCR4-CXCL12 axis in Ewing sarcoma growth was suggested by our observations that i ) CXCR4 expression correlated positively with tumor volume at diagnosis ( p = 0.013 ) , ii ) CXCL12 was present within the microenvironment of virtually all cases , iii ) CXCL12 induced proliferation of CXCR4-positive Ewing sarcoma cell lines , which could be abrogated by AMD3100 . CXCR4 expression was not correlated with occurrence of metastatic disease . Also , therapy-naive tumors demonstrated higher CXCR4 expression as compared to metastases ( p = 0.027 ) . Evaluation of in vivo hypoxia-inducible factor-1alpha expression and culture of cells under hypoxic conditions revealed no role for hypoxia in CXCR4 expression . CONCLUSIONS : Together , our results imply a crucial role for the CXCR4-CXCL12 axis in auto- and/or paracrine growth stimulation . Integration of CXCR4-targeting strategies into first- and/or second-line treatment regimens may represent a promising treatment option for Ewing sarcoma . OUTPUT:

Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The down-regulation of dominant oncogenes , including C-MYC , in tumor cells often leads to the induction of senescence via mechanisms that are not completely identified . In the current study , we demonstrate that MYC-depleted melanoma cells undergo extensive DNA damage that is caused by the underexpression of thymidylate synthase ( TS ) and ribonucleotide reductase ( RR ) and subsequent depletion of deoxyribonucleoside triphosphate pools . Simultaneous genetic inhibition of TS and RR in melanoma cells induced DNA damage and senescence phenotypes very similar to the ones caused by MYC-depletion . Reciprocally , overexpression of TS and RR in melanoma cells or addition of deoxyribo-nucleosides to culture media substantially inhibited DNA damage and senescence-associated phenotypes caused by C-MYC depletion . Our data demonstrate the essential role of TS and RR in C-MYC-dependent suppression of senescence in melanoma cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Androgens regulate both the physiological development of the prostate and the pathology of prostatic diseases . However , the mechanisms by which androgens exert their regulatory activities on these processes are poorly understood . In this study , we have determined that androgens regulate overall cell metabolism and cell growth , in part , by increasing autophagy in prostate cancer cells . Importantly , inhibition of autophagy using either pharmacological or molecular inhibitors significantly abrogated androgen-induced prostate cancer cell growth . Mechanistically , androgen-mediated autophagy appears to promote cell growth by augmenting intracellular lipid accumulation , an effect previously demonstrated to be necessary for prostate cancer cell growth . Further , autophagy and subsequent cell growth is potentiated , in part , by androgen-mediated increases in reactive oxygen species . These findings demonstrate a role for increased fat metabolism and autophagy in prostatic neoplasias and highlight the potential of targeting underexplored metabolic pathways for the development of novel therapeutics .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Testicular Germ Cell Tumors ( TGCT ) and patient-derived cell lines are extremely sensitive to cisplatin and other interstrand cross-link ( ICL ) inducing agents . Nevertheless , a subset of TGCTs are either innately resistant or acquire resistance to cisplatin during treatment . Understanding the mechanisms underlying TGCT sensitivity/resistance to cisplatin as well as the identification of novel strategies to target cisplatin-resistant TGCTs have major clinical implications . Herein , we have examined the proficiency of five embryonal carcinoma ( EC ) cell lines to repair cisplatin-induced ICLs . Using γH2AX staining as a marker of double strand break formation , we found that EC cell lines were either incapable of or had a reduced ability to repair ICL-induced damage . The defect correlated with reduced Homologous Recombination ( HR ) repair , as demonstrated by the reduction of RAD51 foci formation and by direct evaluation of HR efficiency using a GFP-reporter substrate . HR-defective tumors cells are known to be sensitive to the treatment with poly(ADP-ribose) polymerase ( PARP ) inhibitor . In line with this observation , we found that EC cell lines were also sensitive to PARP inhibitor monotherapy . The magnitude of sensitivity correlated with HR-repair reduced proficiency and with the expression levels and activity of PARP1 protein . In addition , we found that PARP inhibition strongly enhanced the response of the most resistant EC cells to cisplatin , by reducing their ability to overcome the damage . These results point to a reduced proficiency of HR repair as a source of sensitivity of ECs to ICL-inducing agents and PARP inhibitor monotherapy , and suggest that pharmacological inhibition of PARP can be exploited to target the stem cell component of the TGCTs ( namely ECs ) and to enhance the sensitivity of cisplatin-resistant TGCTs to standard treatments .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Heparin-binding epidermal growth factor-like growth factor ( HB-EGF ) is a member of the epidermal growth factor family and has a variety of physiological and pathological functions . Modulation of HB-EGF activity might have a therapeutic potential in the oncology area . We explored the therapeutic possibilities by characterizing the in vitro biological activity of anti-HB-EGF monoclonal antibody Y-142 . EGF receptor ( EGFR ) ligand and species specificities of Y-142 were tested . Neutralizing activities of Y-142 against HB-EGF were evaluated in EGFR and ERBB4 signaling . Biological activities of Y-142 were assessed in cancer cell proliferation and angiogenesis assays and compared with the anti-EGFR antibody cetuximab , the HB-EGF inhibitor CRM197 , and the anti-vascular endothelial growth factor ( VEGF ) antibody bevacizumab . The binding epitope was determined with alanine scanning . Y-142 recognized HB-EGF as well as the EGFR ligand amphiregulin , and bound specifically to human HB-EGF , but not to rodent HB-EGF . In addition , Y-142 neutralized HB-EGF-induced phosphorylation of EGFR and ERBB4 , and blocked their downstream ERK1/2 and AKT signaling . We also found that Y-142 inhibited HB-EGF-induced cancer cell proliferation , endothelial cell proliferation , tube formation , and VEGF production more effectively than cetuximab and CRM197 and that Y-142 was superior to bevacizumab in the inhibition of HB-EGF-induced tube formation . Six amino acids in the EGF-like domain were identified as the Y-142 binding epitope . Among the six amino acids , the combination of F115 and Y123 determined the amphiregulin cross-reactivity and that F115 accounted for the species selectivity . Furthermore , it was suggested that the potent neutralizing activity of Y-142 was derived from its recognition of R142 and Y123 and its high affinity to HB-EGF . Y-142 has a potent HB-EGF neutralizing activity that modulates multiple biological activities of HB-EGF including cancer cell proliferation and angiogenic activities . Y-142 may have a potential to be developed into a therapeutic agent for the treatment of HB-EGF-dependent cancers . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Breast cancer incidence is increased in women receiving menopausal hormone therapy with estrogen plus progestin but not with estrogen alone . The use of a tissue-selective estrogen complex ( TSEC ) has been proposed as a novel menopausal hormone therapy strategy to eliminate the requirement for a progestogen . Combination of bazedoxifene ( BZA ) with conjugated estrogens ( CEs ) , the first TSEC , has shown beneficial effects . Whether it would exert antiestrogenic effects on breast cancer is not clear . To address this issue , we compared estradiol ( E(2) ) and CE alone on proliferation and apoptosis in MCF-7 breast cancer cells . CE stimulated growth of MCF-7 cells at a peak concentration 10-fold higher than required for E(2) . Both CE and E(2) alone increased DNA synthesis and reduced apoptosis with activation of MAPK , Akt , and p70S6K and up-regulation of antiapoptotic factors survivin , Bcl-2 , and X-linked inhibitor of apoptosis protein , These effects could be completely blocked by BZA . Gene expression studies demonstrated that CE and E(2) were equally potent on expression of cMyc , pS2 , and WNT1 inducible signaling pathway protein 2 , whereas the stimulatory effects of CE on progesterone receptor and amphiregulin expression were weaker than E(2) . BZA effectively blocked each of these effects and showed no estrogen agonistic effects when used alone . Our results indicate that the stimulatory effects of E(2) or CE on breast cancer cells could be completely abrogated by BZA . These studies imply that the CE/BZA , TSEC , exerts antiestrogenic effects on breast cancer cells and might block the growth of occult breast neoplasms in postmenopausal women , resulting in an overall reduction in tumor incidence .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Gliomas display anoikis resistance , enhanced invasion in to the adjacent brain parenchyma and eventually recur despite using the standard therapies . Our studies on increased anoikis sensitization in matrix metalloproteinase-2 ( MMP-2)-knockdown 4910 and 5310 human glioma xenograft cells were interestingly correlated with p21-activated kinase 4 ( PAK4 ) inhibition , prompting us to further investigate the role of PAK4 in glioma . Here , we report the PAK4 upregulation in positive correlation with increasing glioma pathological grades . The siRNA-mediated PAK4 knockdown elevated anoikis , and inhibited invasion and migration by downregulating MMP-2 , αvβ3-integrin and phospho-epidermal growth factor receptor ( phospho-EGFR ) . The cDNA-PCR arrays revealed a transcriptional suppression of essential proteins involved in cell proliferation and adhesion in PAK4-knockdown cells . Most importantly , glutathione S-transferase pull-down assays demonstrated the MMP-2 as a new PAK4-interacting protein which binds to PAK4 kinase domain . Individual EGFR/ErbB2 inhibitor and αvβ3 antibody treatments in PAK4si-treated cells indicated the regulation of αvβ3/EGFR survival signaling by PAK4 . Overexpression of PAK4 significantly reversed the MMP2si-induced cell death in both cell lines . Codepletion of PAK4 and MMP-2 resulted in robust anoikis-mediated cell death , and severely inhibited invasive and migratory properties in these cells . PAK4si inhibited in vivo tumor growth in nude mice by inhibiting MMP-2 , β3-integrin and phospho-EGFR levels in tumors . Our findings indicate a physical association between PAK4 and MMP-2 , and suggest the future therapeutic potential of PAK4/MMP-2 dual targeting in glioma treatment . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Lowering the threshold of cellular senescence , the process employed by cells to thwart abnormal cell proliferation , though inhibition of CDK2 or Skp2 ( regulator of CDK inhibitors ) has been recently suggested as a potential avenue for cancer treatment . In this study , we employ a published mathematical model of G1/S transition involving the DNA-damage signal transduction pathway to conduct carefully constructed computational experiments to highlight the effectiveness of manipulating cellular senescence in inhibiting damaged cell proliferation . We first demonstrate the suitability of the mathematical model to explore senescence by highlighting the overlap between senescence pathways and those involved in G1/S transition and DNA damage signal transduction . We then investigate the effect of CDK2 deficiency on senescence in healthy cells , followed by effectiveness of CDK2 deficiency in triggering senescence in DNA damaged cells . For this , we focus on the behaviour of CycE , whose peak response indicates G1/S transition , for several reduced CDK2 levels in healthy as well as two DNA-damage conditions to calculate the probability ( β ) or the percentage of CDK2 deficient cells passing G1/S checkpoint ( (1-β) indicates level of senescence ) . Results show that 50% CDK2 deficiency can cause senescence in all healthy cells in a fairly uniform cell population ; whereas , most healthy cells ( ≈67% ) in a heterogeneous population escape senescence . This finding is novel to our study . Under both low- and high-DNA damaged conditions , 50% CDK deficiency can cause 65% increase in senescence in a heterogeneous cell population . Furthermore , the model analyses the relationship between CDK2 and its CKIs ( p21 , p27 ) to help search for other effective ways to bring forward cellular senescence . Results show that the degradation rate of p21 and initial concentration of p27 are effective in lowering CDK2 levels to lower the senescence threshold . Specifically , CDK2 and p27 are the most effective in triggering senescence while p21 having a smaller influence . While receiving experimental support , these findings specify in detail the inhibitory effects of CKIs . However , simultaneous variation of CDK2 and CKIs produces a dramatic reduction of damage cells passing the G1/S with CDK2&p27 combination causing senescence in almost all damaged cells . This combined effect of CDK2&CKIs on senescence is a novel contribution in this study . A review of the crucial protein complexes revealed that the concentration of active CycE/CDK2-p that controls cell cycle arrest provides support for the above findings with CycE/CDK2-p undergoing the largest reduction ( over 100% ) under the combined CDK2&CKI conditions leading to the arrest of most of the damaged cells . Our study thus provides quantitative assessments for the previously published qualitative findings on senescence and highlights new avenues for bringing forward senescence bar . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Aurora A kinase has drawn considerable attention as a therapeutic target for cancer therapy . However , the underlying molecular and cellular mechanisms of the anticancer effects of Aurora A kinase inhibition are still not fully understood . Herein , we show that depletion of Aurora A kinase by RNA interference ( RNAi ) in hepatocellular carcinoma ( HCC ) cells upregulated FoxO1 in a p53-dependent manner , which induces cell cycle arrest . Introduction of an RNAi-resistant Aurora A kinase into Aurora A-knockdown cells resulted in downregulation of FoxO1 expression and rescued proliferation . In addition , silencing of FoxO1 in Aurora A-knockdown cells allowed the cells to exit cytostatic arrest , which , in turn , led to massive cell death . Our results suggest that FoxO1 is responsible for growth arrest at the G 2/M phase that is induced by Aurora A kinase inhibition . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Environmental or occupational exposure to low doses of arsenic induces a series of health problems including cancer . The molecular events in arsenic-induced carcinogenicity remain to be defined . In the NuLi-1 immortalized human lung epithelial cell line with p53 and pRb deficiency , exposure to low doses of arsenic trioxide for 72 h promoted cell proliferation and upregulated the gene transcription levels of FOXM1 , CDC6 , CDC25A , and cyclin D1 , which are both critical cell cycle regulatory genes and proto-oncogenes . Continuous in vitro exposure to 1 �M arsenic trioxide for 34 wks induced malignant cell transformation , as evidenced by enhanced anchorage-independent cell growth . The expression of FOXM1 , CDC6 , CDC25A , and Cyclin D1 was dynamically elevated at the gene transcription and protein levels in the process of cell transformation . The carcinogenic ability of transformed cell colonies coincides with the expression levels of FOXM1 in in vitro anchorage-independent growth assays and in vivo tumor xenograft formation assays . In reverse , the knockdown of FOXM1 in lung adenocarcinoma A549 cells or arsenic-transformed NuLi-1 cells significantly decreased anchorage-independent cell growth and tumor xenograft formation . The transformed NuLi-1 cells showed genomic instability in the form of copy number variation ( CNV ) at chromosome 1 , 5 , 6 , 18 , and 20 , but not loss of heterozygosity ( LOH ) . These results showed for the first time that chronic exposure to low doses of arsenic trioxide promoted lung carcinogenicity , in part by aberrantly upregulating FOXM1 and its associated oncogenes , when the tumor suppressor genes p53 and pRb were inactivated. � 2012 Wiley Periodicals , Inc .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Capsaicin , one of the major pungent ingredients found in red peppers , has been recently demonstrated to induce apoptosis in various malignant cell lines through an unclear mechanism . In this study , the effect of capsaicin on proliferation and apoptosis in the human pancreatic cancer cell line PANC-1 and its possible mechanism(s) of action were investigated . The results of a Cell Counting Kit-8 ( CCK-8 ) assay revealed that capsaicin significantly decreased the viability of PANC-1 cells in a dose-dependent manner . Capsaicin induced G0/G1 phase cell cycle arrest and apoptosis in PANC-1 cells as demonstrated by a flow cytometric assessment . Caspase-3 expression at both the protein and mRNA level was promoted following capsaicin treatment . Furthermore , we revealed that phospho-PI3 Kinase p85 ( Tyr458 ) and phospho-Akt ( Ser473 ) in PANC-1 cells were downregulated in response to capsaicin . Moreover , capsaicin gavage significantly inhibited the growth of pancreatic cancer PANC-1 cell xenografts in athymic nude mice . An increased number of TUNEL-positive cells and cleaved caspase-3 were observed in capsaicin-treated mice . In vivo , capsaicin downregulated the expression of phospho-PI3 Kinase p85 ( Tyr458 ) and phospho-Akt ( Ser473 ) . In conclusion , we have demonstrated that capsaicin is an inhibitor of growth of PANC-1 cells , and downregulation of the phosphoinositide 3-kinase/Akt pathway may be involved in capsaicin-induced apoptosis in vitro and in vivo .

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Sorafenib is a multi-targeted agent and has been reported to have potent antitumor effects against various types of tumors , including human non-small cell lung cancer ( NSCLC ) . In this study , we explored in vitro the antitumor effects of sorafenib alone and in combination with gemcitabine in epidermal growth factor receptor-tyrosine kinase inhibitor ( EGFR-TKI)-resistant human lung cancer cell lines and the related molecular mechanisms . The NSCLC cell lines A549 ( mutant KRAS ) , H1666 ( mutant BRAF ) and H1975 ( mutant EGFR-T790M ) were treated with sorafenib and gemcitabine alone and in combination . The cytotoxicity was assessed by MTT assay , cell cycle distribution was analyzed by flow cytometry , and alterations in signaling pathways were analyzed by western blotting . We found that sorafenib exhibited dose-dependent growth inhibition in all three EGFR-TKI-resistant NSCLC cell lines . When sorafenib was combined with gemcitabine , synergistic activity was observed in the A549 and H1666 cells and antagonistic activity was observed in the H1975 cells . Sorafenib arrested the cell cycle at the G1 phase , whereas gemcitabine arrested the cell cycle at the S phase . Sorafenib inhibited C-RAF and p-ERK in the A549 cells and B-RAF and p-ERK in the H1666 and H1975 cells . The molecular mechanism of this synergism is that RAF/MEK/ERK which are activated by gemcitabine are efficiently suppressed by simultaneously administered sorafenib . By contrast , the mechanism of antagonism may be due to mutual interference with the cell cycle in the H1975 cells . In conclusion , we found that sorafenib exhibits antiproliferative effects in EGFR-TKI-resistant NSCLC cell lines and when combined with gemcitabine demonstrates synergistic activity in A549 and H1666 cells but antagonistic activity in H1975 cells .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Radix of Asiasarum heterotropoides var. mandshuricum F. Maekawa ( A. radix ) has been prescribed for treating pain , allergies and inflammatory disorders in traditional oriental medicine . However , only limited information on the anticancer effects of A. radix is currently available . The aim of this study was to determine the anticancer effect of the ethanol extract of A. radix ( EEAR ) on HCT-116 human colon cancer cells and to investigate its underlying mechanisms of action . EEAR significantly induced G2/M cell cycle arrest and apoptosis in HCT-116 cells . EEAR-induced apoptosis was observed in parallel with activation of caspases and an increased ratio of Bax ( pro-apoptotic)/Bcl2 ( anti-apoptotic ) . Western blot analyses revealed that EEAR elevated the expression of p53 and p21(Waf/Cip1) and decreased the expression of the regulator proteins of G2/M phase progression , such as cdc2 and cyclin B. The upregulation of p53 by EEAR was due to the increased levels of p53 mRNA without a similar increase in proteasome-mediated p53 degradation . EEAR-induced apoptosis in HCT-116 cells was dependent on p53 expression , as determined by siRNA-mediated p53 knockdown . Taken together , these results suggest that EEAR inhibits the growth of the HCT-116 cells through induction of G2/M cell cycle arrest and apoptosis , which are mediated by p53 expression . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Piceatannol has potent anti-inflammatory , immunomodulatory , anticancer and antiproliferative effects . However , little is known about the mechanism by which piceatannol inhibits invasion and metastasis . The aim of the current study was to investigate the effects of piceatannol on the expression of matrix metalloproteinase-9 ( MMP-9 ) in DU145 human prostate cancer cells . The results revealed that MMP-9 activity was significantly increased in response to tumor necrosis factor-α ( TNF-α ) . However , treatment with piceatannol reversed TNF-α- and MMP-9-induced gelatin zymography and its gene expression . In addition , a Matrigel invasion assay determined that piceatannol reduces the TNF-α-induced invasion of DU145 cells . Nuclear factor-κ B ( NF-κB ) is a significant transcription factor that regulates numerous genes involved in tumor cell invasion and metastasis . Therefore , whether piceatannol acts on NF-κB to regulate MMP-9 gene expression was analyzed . The results revealed that piceatannol attenuates MMP-9 gene expression via the suppression of NF-κB activity . Using a specific NF-κB inhibitor , pyrrolidine dithiocarbamate , it was confirmed that TNF-α-induced MMP-9 gene expression is primarily regulated by NF-κB activation . Piceatannol inhibited NF-κB activity by suppressing nuclear translocation of the NF-κB p65 and p50 subunits . Furthermore , TNF-α-induced Akt phosphorylation was significantly downregulated in the presence of piceatannol . The Akt inhibitor LY294002 caused a significant decrease in TNF-α-induced NF-κB activity and MMP-9 gene expression . Overall , these data suggest that piceatannol inhibits TNF-α-induced invasion by suppression of MMP-9 activation via the Akt-mediated NF-κB pathway in DU145 prostate cancer cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Gefitinib , the specific inhibitor of the epidermal growth factor receptor ( EGFR ) , may cause growth delay in cancer cell lines . Thorough understanding of the downstream cellular signaling of gefitinib will facilitate the discovery of biomarkers for predicting outcomes and monitoring anti-EGFR therapies , and provide information for key targets for therapeutic intervention . In this study , we investigated the role of transducer of erbB2.1 ( TOB1 ) in gefitinib therapy . Using the lung carcinoma cell lines A549 and NCI-H1975 , the results suggested that gefitinib might mediate cell cycle arrest in lung cancer cells at least by targeting TOB1 expression . Gefitinib treatment caused cell cycle arrest predominantly at the G1 phase , which is associated with TOB1 nuclear translocation and its interaction with cyclin D1 . We also showed that knockdown of TOB1 expression by RNAi rescued lung cancer cells from gefitinib-induced cell-proliferative arrest . These results suggest that TOB1 interaction with cyclin D1 and nuclear translocation is directly involved in the gefitinib-induced anti-proliferative cell cycle arrest . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Acute leukemia is a disorder of the hematopoietic system characterized by the expansion of a clonal population of cells blocked from differentiating into mature cells . Recent studies have shown that chalcones and their derivatives induce apoptosis in different cell lines . Since new compounds with biological activity are needed , the aim of this study was to evaluate the cytotoxic effect of three synthetic chalcones , derived from 1-naphthaldehyde and 2-naphthaldehyde , on human acute myeloid leukemia K562 cells and on human acute lymphoblastic leukemia Jurkat cells . Based on the results , the most cytotoxic compound ( A1 ) was chosen for further analysis in six human acute leukemia cells and in a human colon adenocarcinoma cell line ( HT-29 ) . Chalcone A1 significantly reduced the cell viability of K562 , Jurkat , Kasumi , U937 , CEM and NB4 cells in a concentration and time-dependent manner when compared with the control group ( IC(50) values between ∼1.5μM and 40μM ) . It was also cytotoxic to HL-29 cells . To further examine its effect on normal cells , peripheral blood lymphocytes collected from healthy volunteers were incubated with the compound . It has also been incubated with human fibroblasts cultured from bone marrow ( JMA ) . Chalcone A1 is non-cytotoxic to PBL cells and to JMA cells . A1 caused significant cell cycle arrest in all phases according to the cell line , and increased the proportion of cells in the sub G0/G1 phase . To evaluate whether this chalcone induced cell death via an apoptotic or necrotic pathway , cell morphology was examined using fluorescence microscopy . Cells treated with A1 at IC(50) demonstrated the morphological characteristic of apoptosis , such as chromatin condensation and formation of apoptotic bodies . Apoptosis was confirmed by externalization of phosphatidylserine , which was detected by the Annexin V-FITC method , and by DNA fragmentation . The results suggest that chalcone A1 has potential as a new lead compound for cancer therapy . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Metformin is a well-established diabetes drug that prevents the onset of most types of human cancers in diabetic patients , especially by targeting cancer stem cells . Metformin exerts its protective effects by functioning as a weak " mitochondrial poison, " as it acts as a complex I inhibitor and prevents oxidative mitochondrial metabolism ( OXPHOS ) . Thus , mitochondrial metabolism must play an essential role in promoting tumor growth . To determine the functional role of " mitochondrial health " in breast cancer pathogenesis , here we used mitochondrial uncoupling proteins ( UCPs ) to genetically induce mitochondrial dysfunction in either human breast cancer cells ( MDA-MB-231 ) or cancer-associated fibroblasts ( hTERT-BJ1 cells ) . Our results directly show that all three UCP family members ( UCP-1/2/3 ) induce autophagy and mitochondrial dysfunction in human breast cancer cells , which results in significant reductions in tumor growth . Conversely , induction of mitochondrial dysfunction in cancer-associated fibroblasts has just the opposite effect . More specifically , overexpression of UCP-1 in stromal fibroblasts increases β-oxidation , ketone body production and the release of ATP-rich vesicles , which " fuels " tumor growth by providing high-energy nutrients in a paracrine fashion to epithelial cancer cells . Hence , the effects of mitochondrial dysfunction are truly compartment-specific . Thus , we conclude that the beneficial anticancer effects of mitochondrial inhibitors ( such as metformin ) may be attributed to the induction of mitochondrial dysfunction in the epithelial cancer cell compartment . Our studies identify cancer cell mitochondria as a clear target for drug discovery and for novel therapeutic interventions . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Background:Sorafenib is the only drug approved for the treatment of hepatocellular carcinoma ( HCC ) . The bioenergetic propensity of cancer cells has been correlated to anticancer drug resistance , but such correlation is unclear in sorafenib resistance of HCC.Methods:Six sorafenib-naive HCC cell lines and one sorafenib-resistant HCC cell line ( Huh-7R ; derived from sorafenib-sensitive Huh-7 ) were used . The bioenergetic propensity was calculated by measurement of lactate in the presence or absence of oligomycin . Dichloroacetate ( DCA ) , a pyruvate dehydrogenase kinase ( PDK ) inhibitor , and siRNA of hexokinase 2 ( HK2 ) were used to target relevant pathways of cancer metabolism . Cell viability , mitochondrial membrane potential , and sub-G1 fraction were measured for in vitro efficacy . Reactive oxygen species ( ROS ) , adenosine triphosphate ( ATP ) and glucose uptake were also measured . A subcutaneous xenograft mouse model was used for in vivo efficacy.Results:The bioenergetic propensity for using glycolysis correlated with decreased sorafenib sensitivity ( R(2)=0.9067 , among sorafenib-naive cell lines ; P=0.003 , compared between Huh-7 and Huh-7 R ) . DCA reduced lactate production and increased ROS and ATP , indicating activation of oxidative phosphorylation ( OXPHOS ) . DCA markedly sensitised sorafenib-resistant HCC cells to sorafenib-induced apoptosis ( sub-G1 ( combination vs sorafenib ) : Hep3B , 65.4±8.4% vs 13±2.9% ; Huh-7 R , 25.3± 5.7% vs 4.3±1.5% ; each P<0.0001 ) , whereas siRNA of HK2 did not . Sorafenib ( 10 mg kg(-1) per day ) plus DCA ( 100 mg kg(-1) per day ) also resulted in superior tumour regression than sorafenib alone in mice ( tumour size : -87% vs -36% , P<0.001).Conclusion:The bioenergetic propensity is a potentially useful predictive biomarker of sorafenib sensitivity , and activation of OXPHOS by PDK inhibitors may overcome sorafenib resistance of HCC.British Journal of Cancer advance online publication , 20 December 2012 ; doi:10.1038/bjc.2012.559 www.bjcancer.com .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Trinucleotide repeat ( TNR ) expansions and deletions are associated with human neurodegenerative diseases and prostate cancer . Recent studies have pointed to a linkage between oxidative DNA damage , base excision repair ( BER ) and TNR expansion , which is demonstrated by the observation that DNA polymerase β ( pol β ) gap-filling synthesis acts in concert with alternate flap cleavage by flap endonuclease 1 ( FEN1 ) to mediate CAG repeat expansions . In this study , we provide the first evidence that the repair of a DNA base lesion can also contribute to CAG repeat deletions that were initiated by the formation of hairpins on both the template and the damaged strand of a continuous run of ( CAG)(20 ) or ( CAG)(25 ) repeats . Most important , we found that pol β not only bypassed one part of the large template hairpin but also managed to pass through almost the entire length of small hairpin . The unique hairpin bypass of pol β resulted in large and small deletions in coordination with FEN1 alternate flap cleavage . Our results provide new insight into the role of BER in modulating genome stability that is associated with human diseases . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: PURPOSE : Prostate cancer ( PCa ) development is often associated with deletion or silencing of tumor suppressor PTEN , a negative regulator of the PI3K-Akt pathway , leading to resistance to various therapies . Therefore , the PI3K/Akt pathway plays a central role in various cellular processes leading to malignant phenotype , and , consequently is an attractive target . However , the efficacy of AKT inhibitors is limited by resistance mechanisms that result in minimal tumor cell death . Methods:Effects of Akt inhibitor AZD5363 were investigated on cell proliferation , apoptosis , Akt pathway and survival mechanisms . We then examined the impacts of inhibition of autophagy combined with AZD5363 on cell proliferation and apoptosis . Furthermore , the anti-cancer activity of combination treatment of the lysosomotropic inhibitor of autophagy ( chloroquine ) with Akt inhibitor AZD5363 was evaluated in PC-3 prostate cancer xenografts . RESULTS : we show that AZD5363 affected Akt downstream pathway by reducing p-mTOR , p-P70S6K and p-S6K . While AZD5363 monotherapy induced G2 growth arrest and autophagy , it failed to induce significant apoptosis in PC-3 and DU145 PCa cells . Blocking autophagy using pharmacological inhibitors or genetic inhibitors enhanced cell death induced by AZD5363 in these PCa cells . Importantly , the combination of AZD5363 with chloroquine significantly reduced tumor volume by 84.9% compared with the control group and by 77.5% compared with either drug alone in PC3 xenografts . CONCLUSIONS : These data demonstrate that Akt inhibitor AZD5363 , synergizes with the lysosomotropic inhibitor of autophagy , chloroquine , to induce apoptosis and delay tumor progression in PCa models that are resistant to monotherapy AZD5363 , providing a new therapeutic approach potentially translatable to patients .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: BACKGROUND : Although quiescence ( reversible cell cycle arrest ) is a key part in the life history and fate of many mammalian cell types , the mechanisms of gene regulation in quiescent cells are poorly understood . We sought to clarify the role of microRNAs as regulators of the cellular functions of quiescent human fibroblasts . RESULTS : Using microarrays , we discovered that the expression of the majority of profiled microRNAs differed between proliferating and quiescent fibroblasts . Fibroblasts induced into quiescence by contact inhibition or serum starvation had similar microRNA profiles , indicating common changes induced by distinct quiescence signals . By analyzing the gene expression patterns of microRNA target genes with quiescence , we discovered a strong regulatory function for miR-29 , which is downregulated with quiescence . Using microarrays and immunoblotting , we confirmed that miR-29 targets genes encoding collagen and other extracellular matrix proteins and that those target genes are induced in quiescence . In addition , overexpression of miR-29 resulted in more rapid cell cycle re-entry from quiescence . We also found that let-7 and miR-125 were upregulated in quiescent cells . Overexpression of either one alone resulted in slower cell cycle re-entry from quiescence , while the combination of both together slowed cell cycle re-entry even further . CONCLUSIONS : microRNAs regulate key aspects of fibroblast quiescence including the proliferative state of the cells as well as their gene expression profiles , in particular , the induction of extracellular matrix proteins in quiescent fibroblasts .

However , the tumor cell lines commonly employed for prostate cancer research express only small amounts of MMPs when cultivated as monolayer cultures , in common culture media . The present study was conducted to ascertain whether culture conditions that include fibronectin can alter MMP2 and MMP9 expression by the human prostatic epithelial cell lines RWPE-1 , LNCaP and PC-3 . These cells were individually seeded at 2×10(4) cells/cm(2) , cultivated until they reached 80% confluence , and then exposed for 4h to fibronectin , after which the conditioned medium was analyzed by gelatin zymography . Untreated cells were given common medium . Only RWPE-1 cells express detectable amounts of MMP9 when cultivated in common medium , whereas the addition of fibronectin induced high expression levels of pro and active forms of MMP2 in all tested cell lines . Our findings demonstrate that normal and tumor prostate cell lines express MMP2 activity when in contact with extracellular matrix components or blood plasma proteins such as fibronectin . Future studies of transcriptomes and proteomes in prostate cancer research using these cell lines should not neglect these important conclusions . OUTPUT:

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: p53 plays an important role in regulating a wide variety of cellular processes , such as cell cycle arrest and/or apoptosis . Dysfunction of p53 is frequently associated with several pathologies , such as cancer and neurodegenerative diseases . In recent years substantial progress has been made in developing novel p53-activating molecules . Importantly , modulation of p53 interaction with its main inhibitor , Mdm2 , has been highlighted as a promising therapy target . In this regard , bimolecular fluorescence complementation ( BiFC ) analysis , by providing direct visualization of protein interactions in living cells , offers a straightforward method to identify potential modulators of protein interactions . In this study , we developed a simple and robust Venus-based BiFC system to screen for modulators of p53-p53 and p53-Mdm2 interactions in live mammalian cells . We used nutlin-3 , a well-known disruptor of p53-Mdm2 interaction , to validate the specificity of the assay . The reduction of BiFC signal mediated by nutlin-3 was correlated with an increase in Puma transactivation , PARP cleavage , and cell death . Finally , this novel BiFC approach was exploited to identify potential modulators of p53-Mdm2 complex formation among a commercially available chemical library of 33 protein phosphatase inhibitors . Our results constitute " proof-of-concept " that this model has strong potential as an alternative to traditional target-based drug discovery strategies . Identification of new modulators of p53-p53 and p53-Mdm2 interactions will be useful to achieve synergistic drug efficacy with currently used anti-tumor therapies . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Breast cancer constitutes a major health problem for women worldwide . However , its incidence varies between populations and geographical locations . These variations could be diet-related , since there are several carcinogenic compounds in the modern diet , while natural products contain various anti-cancer elements . Several lines of evidence indicate that , in addition to their clear preventive effect , these compounds could also be used as therapeutic agents . In the present report we have shown that oleuropein , a pharmacologically safe natural product of olive leaf , has potent anti-breast cancer properties . Indeed , oleuropein exhibits specific cytotoxicity against breast cancer cells , with higher effect on the basal-like MDA-MB-231 cells than on the luminal MCF-7 cells . This effect is mediated through the induction of apoptosis via the mitochondrial pathway . Moreover , oleuropein inhibits cell proliferation by delaying the cell cycle at S phase and up-regulated the cyclin-dependent inhibitor p21 . Furthermore , oleuropein inhibited the anti-apoptosis and pro-proliferation protein NF-κB and its main oncogenic target cyclin D1 . This inhibition could explain the great effect of oleuropein on cell proliferation and cell death of breast cancer cells . Therefore , oleuropein warrants further investigations to prove its utility in preventing/treating breast cancer , especially the less-responsive basal-like type . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: PURPOSE : Acid ceramidase ( AC ) occupies an important place in the control of cancer cell proliferation . We tested the influence of AC inhibition on the effects of PSC 833 , a P-glycoprotein antagonist with potent ceramide-generating capacity , to determine whether AC could be a therapeutic target in pancreatic cancer . METHODS : Ceramide metabolism was followed using ( 3)H-palmitate , and molecular species were determined by mass spectroscopy . Apoptosis was measured by DNA fragmentation , autophagy by acridine orange staining , and cell cycle was assessed by flow cytometry and RB phosphorylation . AC was measured in intact cells using fluorescent substrate . RESULTS : Exposure of human PANC-1 or MIA-PaCa-2 cells to PSC 833 promoted increases in de novo ( dihydro)ceramides , ( dihydro)glucosylceramides , and ( dihydro)sphingomyelins , demarking ceramide generation and robust metabolism . Despite the multifold increases in ( dihydro)ceramide levels , cells were refractory to PSC 833 . However , PSC 833 produced a dose-dependent decrease in DNA synthesis and dose- and time-dependent decreases in RB phosphorylation , consistent with cell cycle arrest as demonstrated at G1 . Cytostatic effects of PSC 833 were converted to cytotoxic end-point by acid ceramidase inhibition . Cytotoxicity was accompanied by formation of acridine orange-stained acidic vesicles and an increase in LC3 expression , indicative of autophagic response . Cell death was not reversed by preexposure to myriocin , which blocks PSC 833-induced ceramide generation . CONCLUSION : Although the role of ceramide in end-point cytotoxicity is unclear , our results suggest that acid ceramidase is a viable target in pancreatic cancer . We propose that AC inhibition will be effective in concert with other anticancer therapies . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Epirubicin was developed as a semi-synthetic anthracycline derivative to circumvent the cardiotoxic limitations associated with the use of doxorubicin in the clinic . Anthracycline compounds have been demonstrated to form covalent drug-DNA adducts utilising endogenous and exogenous sources of formaldehyde ; however , previous investigations of the formation of epirubicin-DNA adducts provide conflicting evidence for adduct formation . This work provides evidence that epirubicin acts to form drug-DNA adducts at physiologically relevant concentrations and demonstrates that the rate of formation of epirubicin-DNA adducts is slower than that observed for other anthracycline compounds , explaining why they are only detectable under defined experimental conditions . Formation of covalent epirubicin-DNA adducts improves the apoptotic profile of epirubicin and provides opportunities to overcome drug resistance and cardiotoxic limitations . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The mechanisms by which tumour cells metastasize and the role that cell polarity proteins play in this process are not well understood . We report that partitioning defective protein 3 ( Par3 ) is dysregulated in metastasis in human breast cancer , and is associated with a higher tumour grade and ErbB2-positive status . Downregulation of Par3 cooperated with ErbB2 to induce cell invasion and metastasis in vivo . Interestingly , the metastatic behaviour was not associated with an overt mesenchymal phenotype . However , loss of Par3 inhibited E-cadherin junction stability , disrupted membrane and actin dynamics at cell-cell junctions and decreased cell-cell cohesion in a manner dependent on the Tiam1/Rac-GTP pathway . Inhibition of this pathway restored E-cadherin junction stability and blocked invasive behaviour of cells lacking Par3 , suggesting that loss of Par3 promotes metastatic behaviour of ErbB2-induced tumour epithelial cells by decreasing cell-cell cohesion .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: BACKGROUND : CD81 is a transmembrane protein that serves as a putative receptor for hepatitis C virus . In addition , CD81 has been suggested to be involved in a broad range of other cellular functions . Its putative implication in tumorigenesis has so far , however , remained largely unexplored . To assess the candidacy of CD81 as a tumor suppressor in gastric cancer development , we investigated its expression and function in a series of primary gastric tumors and gastric tumor-derived cell lines . METHODS : The expression and concomitant methylation status of the CD81 gene and its effect on tumor development and cellular signaling were evaluated . RESULTS : CD81 mRNA levels were found to be low in 16 of 40 ( 40% ) primary tumors and 9 of 14 ( 64.2% ) cell lines , and these low expression levels were found to correlate with the stage and grade of the tumors . Genomic alterations of CD81 were not encountered , whereas its expression could be re-activated in low expressing cells upon 5-aza-dC treatment . Bisulfite DNA sequencing analysis of 10 CpG sites within the 5 ' proximal region of the CD81 gene promoter revealed that the observed transcriptional silencing was tightly associated with aberrant hypermethylation . Subsequent restoration of CD81 expression induced a G(1) cell cycle arrest and apoptosis , whereas siRNA-mediated CD81 down-regulation promoted cell proliferation and attenuated cellular responses to various apoptotic stress stimuli . Also the colony-forming ability of the tumor cells could be inhibited and enhanced through CD81 up- and down-regulation , respectively . CD81 was found to inhibit p38 ( but not ERK , JNK and AKT ) phosphorylation and its growth suppressive effect could be abolished through p38 up- and down-regulation . CONCLUSION : From our data we conclude that epigenetic inactivation of CD81 is a common feature of gastric tumors and that this inactivation may render growth and survival advantages to the tumor cells , at least partially through p38 signaling .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Pterostilbene , a polyphenolic compound present in grapes and other fruits , has been demonstrated to inhibit growth and induce apoptosis and autophagy in some cancer cell types . We found that pterostilbene at the IC90 concentration of 44 �M inhibited proliferation and induced apoptosis in MOLT4 human leukemia cells . Treatment with pterostilbene resulted in a transient accumulation of cells in the G0/G1-cell cycle phase followed by the S-phase arrest . Pterostilbene-induced apoptotic death of MOLT4 cells was mediated by caspase-3 activation and was accompanied by the disruption of mitochondrial membrane potential , phosphatidylserine externalization and internucleosomal DNA fragmentation . Our results suggest that pterostilbene could serve as a potential additional chemotherapeutic agent for the treatment of leukemia . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Context:The ubiquitin-proteasome system and macroautophagy are two major pathways for intracellular protein degradation . Emerging lines of evidence have shown that blockade of ubiquitin-proteasome system by proteasome inhibitors activates macroautophagy.Objective:The purpose of this study was to determine the involvement of autophagy essential gene Beclin 1 in cytotoxicity of thyroid cancer cells mediated by proteasome inhibitors.Design:Autophagy was measured by acidic-trophic dye staining and EGF-LC3 distribution using fluorescence microscopy , as well as LC3-II transition using Western blot . To ascertain the effect of Beclin 1 , cells were transfected with Beclin 1 plasmid or shRNA against Beclin 1 . Cell viability and apoptotic cells were measured using MTT assay and flow cytometry , respectively.Results:Proteasome inhibitors decreased Beclin 1 expression . In addition , treatment with PI3K inhibitors 3-MA or wortmannin , as well as knockdown of Beclin 1 expression , was unable to affect autophagic responses mediated by proteasome inhibitors . Overexpression of Beclin 1 enhanced proteasome inhibitor-mediated cytotoxicity of thyroid cancer cells via suppression of survivin.Conclusions:Proteasome inhibitors cause Beclin 1-independent macroautophagic responses of thyroid cancer cells in a Beclin 1-independent manner . Beclin 1 possesses autophagy-independent antitumoral effects upon exposure of thyroid cancer cells to proteasome inhibitors . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Kaposi sarcoma is the most common neoplasm caused by Kaposi sarcoma-associated herpesvirus ( KSHV ) . It is prevalent among the elderly in the Mediterranean , inhabitants of sub-Saharan Africa , and immunocompromised individuals such as organ transplant recipients and AIDS patients . Current treatments for Kaposi sarcoma can inhibit tumor growth but are not able to eliminate KSHV from the host . When the host's immune system weakens , KSHV begins to replicate again , and active tumor growth ensues . New therapeutic approaches are needed . Cannabidiol ( CBD ) , a plant-derived cannabinoid , exhibits promising antitumor effects without inducing psychoactive side effects . CBD is emerging as a novel therapeutic for various disorders , including cancer . In this study , we investigated the effects of CBD both on the infection of endothelial cells ( ECs ) by KSHV and on the growth and apoptosis of KSHV-infected ECs , an in vitro model for the transformation of normal endothelium to Kaposi sarcoma . While CBD did not affect the efficiency with which KSHV infected ECs , it reduced proliferation and induced apoptosis in those infected by the virus . CBD inhibited the expression of KSHV viral G protein-coupled receptor ( vGPCR ) , its agonist , the chemokine growth-regulated protein α ( GRO-α ) , vascular endothelial growth factor receptor 3 ( VEGFR-3 ) , and the VEGFR-3 ligand , vascular endothelial growth factor C ( VEGF-C ) . This suggests a potential mechanism by which CBD exerts its effects on KSHV-infected endothelium and supports the further examination of CBD as a novel targeted agent for the treatment of Kaposi sarcoma .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: A predictive mathematical model of the transition from the G2 phase in the cell cycle to mitosis ( M ) was constructed from the known interactions of the proteins that are thought to play significant roles in the G2 to M transition as well as the DNA damage- induced G2 checkpoint . The model simulates the accumulation of active cyclin B1/Cdk1 ( MPF ) complexes in the nucleus to activate mitosis , the inhibition of this process by DNA damage , and transport of component proteins between cytoplasm and nucleus . Interactions in the model are based on activities of individual phospho-epitopes and binding sites of proteins involved in G2/M . Because tracking phosphoforms leads to combinatorial explosion , we employ a rule-based approach using the BioNetGen software . The model was used to determine the effects of depletion or over-expression of selected proteins involved in the regulation of the G2 to M transition in the presence and absence of DNA damage . Depletion of Plk1 delayed mitotic entry and recovery from the DNA damage-induced G2 arrest and over-expression of MPF attenuated the DNA damage-induced G2 delay . The model recapitulates the G2 delay observed in the biological response to varying levels of a DNA damage signal . The model produced the novel prediction that depletion of pkMyt1 results in an abnormal biological state in which G2 cells with DNA damage accumulate inactive nuclear MPF . Such a detailed model may prove useful for predicting DNA damage G2 checkpoint function in cancer and , therefore , sensitivity to cancer therapy . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: γ-Tocotrienol and sesamin are phytochemicals that display potent anticancer activity . Since sesamin inhibits the metabolic degradation of tocotrienols , studies were conducted to determine if combined treatment with sesamin potentiates the antiproliferative effects of γ-tocotrienol on neoplastic mouse ( +SA ) and human ( MCF-7 and MDA-MB-231 ) mammary cancer cells . Results showed that treatment with γ-tocotrienol or sesamin alone induced a significant dose-responsive growth inhibition , whereas combination treatment with these agents synergistically inhibited the growth of +SA , MCF-7 and MDA-MB-231 mammary cancer cells , while similar treatment doses were found to have little or no effect on normal ( mouse CL-S1 and human MCF-10A ) mammary epithelial cell growth or viability . However , sesamin synergistic enhancement of γ-tocotrienol-induced anticancer effects was not found to be mediated from a reduction in γ-tocotrienol metabolism . Rather , combined treatment with subeffective doses of γ-tocotrienol and sesamin was found to induce G1 cell cycle arrest , and a corresponding decrease in cyclin D1 , CDK2 , CDK4 , CDK6 , phospho-Rb , and E2F1 levels , and increase in p27 and p16 levels . Additional studies showed that the antiproliferative effect of combination treatment did not initiate apoptosis or result in a decrease in mammary cancer cell viability . Taken together , these findings indicate that the synergistic antiproliferative action of combined γ-tocotrienol and sesamin treatment in mouse and human mammary cancer cells is cytostatic , not cytotoxic , and results from G1 cell cycle arrest .

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Bone marrow transplantation ( BMT ) , used to treat severe hematological malignancies , often leads to potentially fatal acute graft-versus-host disease ( GVHD ) , despite attempts for better matching and/or use of immune suppressive agents . We reported that embryo-derived PreImplantation-Factor plays a determining role in developing maternal/host tolerance towards the semi/allogenic embryo and regulating systemic immune response . Synthetic PIF ( PIF ) treatment is effective preventing immune attack in non-pregnant models of autoimmunity . Herein , we test PIF ability to prevent acute GVHD development in semi or totally allogenic murine models . We examine PIF's regulatory effect in vivo and in vitro , to control deleterious GVHD while maintaining its ability to preserve beneficial graft vs. leukemia ( GVL effect ) . Bone marrow and spleen cells from C57BL/6 donors were transplanted to semi-allogenic ( C57BL/6�BALB/c ) F1 or allogenic ( BALB/c ) recipients , and then treated with PIF1mg/kg/day/2weeks . Short-term PIF administration reduced acute GVHD in both models and increased survival for up to four months after semi-(or totally ) allogenic BMT . The obtained effect was coupled with lessened skin ( semi-allogenic ) and decreased liver inflammation ( both models ) as well as reduced colon ulceration ( allogenic ) . Both GVHD associated cytokines and chemokines gene expression were decreased in the liver . PIF further lowered circulating interleukin-17 , but not interferon-γ levels . PIF treatment was demonstrated in vivo and in vitro to lead to decreased iNOS expression and in LPS-activated macrophages to lower nitric oxide secretion . Significantly , PIF did not impair the beneficial GVL effect in the B-cell leukemia model . PIF primarily acts by inducing regulatory phenotype on monocytes/APC , which controls T-cell proliferation . Overall our data demonstrates that PIF protects against semi/allogenic GVHD long-term by reducing both target organ and systemic inflammation and by lowering oxidative stress , all while preserving the beneficial GVL effect .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: There are many growth factors influencing the expansion of multiple myeloma ( MM ) . Angiogenesis is a process that may enhance MM growth , in various manners . Among them , insulin-like growth factor-1 ( IGF-1 ) is a major factor , acting in many levels . The aim of the study was to measure serum levels of IGF-1 in newly diagnosed MM patients and to correlate them with clinical stage of the disease and with markers of angiogenesis , such as vascular endothelial growth factor ( VEGF ) , hepatocyte growth factor ( HGF ) , and interleukin-6 and 15 ( IL-6 and IL-15 ) . Serum levels of the above factors were measured , by ELISA , in 57 newly diagnosed MM patients and in 20 healthy controls . There was no difference in serum levels of IGF-1 in MM patients and in controls , contrary to angiogenic factors , which were higher in MM patients ( p &lt ; 0.001 ) . Similarly , IGF-1 did not correlate with clinical stage of the disease nor the other angiogenic factors , which also correlated with each other ( p &lt ; 0.001 ) . Serum IGF-1 concentrations are not influenced in MM patients . Therefore , although it is a proliferation cytokine , it cannot be used as marker of disease activity . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: DNA damage signaling and repair take place in a chromatin context . Consequently , chromatin-modifying enzymes , including adenosine triphosphate-dependent chromatin remodeling enzymes , play an important role in the management of DNA double-strand breaks ( DSBs ) . Here , we show that the p400 ATPase is required for DNA repair by homologous recombination ( HR ) . Indeed , although p400 is not required for DNA damage signaling , DNA DSB repair is defective in the absence of p400 . We demonstrate that p400 is important for HR-dependent processes , such as recruitment of Rad51 to DSB ( a key component of HR ) , homology-directed repair , and survival after DNA damage . Strikingly , p400 and Rad51 are present in the same complex and both favor chromatin remodeling around DSBs . Altogether , our data provide a direct molecular link between Rad51 and a chromatin remodeling enzyme involved in chromatin decompaction around DNA DSBs . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: ABSTRACT : BACKGROUND : Survivin , a member of the family of inhibitor of apoptosis proteins , functions as a key regulator of mitosis and programmed cell death . YM155 , a novel molecular targeted agent , suppresses survivin , which is overexpressed in many tumor types . The aim of this study was to determine the antitumor activity of YM155 in SK-NEP-1 cells . METHODS : SK-NEP-1 cell growth in vitro and in vivo was assessed by MTT and nude mice experiments . Annexin V/propidium iodide staining followed by flow cytometric analysis was used to detect apoptosis in cell culture . Then gene expression profile of tumor cells treated with YM155 was analyzed with real-time PCR arrays . We then analyzed the expression data with MEV ( Multi Experiment View ) cluster software . Datasets representing genes with altered expression profile derived from cluster analyses were imported into the Ingenuity Pathway Analysis tool . RESULTS : YM155 treatment resulted in inhibition of cell proliferation of SK-NEP-1cells in a dose-dependent manner . Annexin V assay , cell cycle , and activation of caspase-3 demonstrates that YM155 induced apoptosis in SK-NEP-1 cells . YM155 significantly inhibited growth of SK-NEP-1 xenografts ( YM155 5 mg/kg : 1.45 +/- 0.77 cm3 ; YM155 10 mg/kg : 0.95 +/- 0.55 cm3 ) compared to DMSO group ( DMSO : 3.70 +/- 2.4 cm3 ) or PBS group cells ( PBS : 3.78 +/- 2.20 cm3 , ANOVA P &lt ; 0.01 ) . YM155 treatment decreased weight of tumors ( YM155 5 mg/kg : 1.05 +/- 0.24 g ; YM155 10 mg/kg : 0.72 +/- 0.17 g ) compared to DMSO group ( DMSO : 2.06 +/- 0.38 g ) or PBS group cells ( PBS : 2.36 +/- 0.43 g , ANOVA P &lt ; 0.01 ) . Real-time PCR array analysis showed between Test group and control group there are 32 genes significantly up-regulated and 54 genes were significantly down-regulated after YM155 treatment . Ingenuity pathway analysis ( IPA ) showed cell death was the highest rated network with 65 focus molecules and the significance score of 44 . The IPA analysis also groups the differentially expressed genes into biological mechanisms that are related to cell death , cellular function maintenance , cell morphology , carbohydrate metabolism and cellular growth and proliferation . Death receptor signaling ( 3.87E-19 ) , TNFR1 signaling , induction of apoptosis by HIV1 , apoptosis signaling and molecular mechanisms of cancer came out to be the top four most significant pathways . IPA analysis also showed top molecules up-regulated were BBC3 , BIRC3 , BIRC8 , BNIP1 , CASP7 , CASP9 , CD5 , CDKN1A , CEBPG and COL4A3 , top molecules down-regulated were ZNF443 , UTP11L , TP73 , TNFSF10 , TNFRSF1B , TNFRSF25 , TIAF1 , STK17A , SST and SPP1 , upstream regulator were NR3C1 , TP53 , dexamethasone , TNF and Akt . CONCLUSIONS : The present study demonstrates that YM155 treatment resulted in apoptosis and inhibition of cell proliferation of SK-NEP-1cells . YM155 had significant role and little side effect in the treatment of SK-NEP-1 xenograft tumors . Real-time PCR array analysis firstly showed expression profile of genes dyes-regulated after YM155 treatment . IPA analysis also represents new molecule mechanism of YM155 treatment , such as NR3C1 and dexamethasone may be new target of YM155 . And our results may provide new clues of molecular mechanism of apoptosis induced by YM155 . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: We report a case of recurrent gastric cancer successfully treated by a combination of CPT-11 and CDDP as the third- line chemotherapy . A 78-year-old man with advanced gastric cancer underwent a curative distal gastrectomy . Three years later , the tumor marker level began to rise and computed tomography ( CT ) revealed lymph node metastasis invading the pancreas resulting in pancreatic duct dilatation . S-1 treatment was initiated but was discontinued because of a systemic exanthem . Paclitaxel was administrated as secondary chemotherapy . But , after 2 courses , a further increase in the tumor marker level and portal vein invasion were observed . Combination therapy of CPT-11 and CDDP was administered as the third-line chemotherapy . After 3 courses , the tumor marker level normalized , tumor size decreased , and the invasion was eliminated . Third-line chemotherapy against recurrent gastric cancer should be considered if patient performance status ( PS ) is maintained . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Vaccination is , in theory , a safe and effective approach for controlling disseminated or metastatic cancer due to the specificity of the mammalian immune system , yet its success in the clinic has been hampered thus far by the problem of immune tolerance to tumor self-antigen . Here we describe a DNA vaccination strategy that is able to control cancer by overcoming immune tolerance to tumor self-antigen . We engineered a DNA construct encoding a dimeric form of a secreted single chain trimer of major histocompatibility complex class I heavy chain , β2-microglobulin , and peptide antigen linked to immunoglobulin G ( SCT-Ag/IgG ) . The chimeric protein was able to bind to antigen-specific CD8+ T cells with nearly 100% efficiency and strongly induce their activation and proliferation . In addition , the chimeric protein was able to coat professional antigen-presenting cells through the Fc receptor to activate antigen-specific CD8+ T cells . Furthermore , intradermal vaccination with DNA encoding SCT-Ag/IgG could generate significant numbers of cytotoxic effector T cells against tumor self-antigen and leads to successful therapeutic outcomes in a preclinical model of metastatic melanoma . Our data suggest that the DNA vaccine strategy described in the current study is able to break immune tolerance against endogenous antigen and result in potent therapeutic antitumor effects . Such strategy may be used in other antigenic systems for the control of infections and/or cancers . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Abstract Purpose : Cell death is one of the most important endpoints of radiosensitivity . The tumor suppressor p53 participates not only in regulation of apoptosis , but also in autophagy mechanism . In this study , H1299-P53 ( with wild-type p53 ) and H1299-175H ( with mutant 175H ) were used , and the effects of p53 on radiosensitivity were analyzed . Methods : Cell models with different p53 status were established by gene engineering , and cell viability was examined by colony formation assay , and cell counting kit-8 ( CCK-8 ) , 3-Methyladenine , and Z-VAD were used to block autophagy and apoptosis , respectively . Western blot was used to detect protein expression ; monodansylcadaverine ( MDC ) staining was used to analyze autophagy rate ; DAPI/Propidium Iodide ( PI ) staining and flow cytometry were used to assess apoptosis and necrosis . Results : In parental H1299 , H1299-P53 , and H1299-175H cells , radiosensitivity exhibited different by colony formation and CCK-8 assay ( D0 : 1.764 Gy , 1.407 Gy and 1.695 Gy ; Dq : 2.977 Gy , 1.199 Gy and 2.312 Gy in turn ) . The radiosensitization of p53 was associated with the increase of MDM2 and P21 expression . The ionizing radiation ( IR)-induced apoptosis was significant in H1299-P53 compared with in H1299 and H199-175H ( p<0.05 ) by flow cytometry , and the expression of cleaved-caspase3 was increased in H1299-P53 cells . While the IR-induced autophagy was significant in H1299 cells ( p<0.01 ) and decreased in H1299-P53 and H1299-175H cells ( p<0.01 ) by MDC staining , the expression of MAPLC3II and Beclin-1 increased in H1299 , but not in H1299-p53 and H199-175H cells . The IR-induced cell survival was significantly increased by Z-VAD-FMK and decreased by 3MA in H1299-P53 cells ; IR- induced autophagy was significantly increased by Z-VAD-FMK in H1299-P53 cells ( p<0.01 ) , but not changed in H1299 cells . Conclusion : p53 could regulate radiosensitivity by inhibiting autophagy and activating apoptosis ; autophagy provides a prosurvival mechanism , and p53 potently abrogated the IR-induced autophagy , while mutant 175H shown no effect on radiosensitivity , suggesting that individual treatment strategies should be based on p53 status in patients .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Sunitinib is an oral multitargeted receptor tyrosine kinase inhibitor with antiangiogenic and antitumor activity that mainly targets vascular endothelial growth factor receptors , and recently , it has been shown to be an active agent for the treatment of malignant pheochromocytomas . Previously , we demonstrated that sunitinib directly inhibited mTORC1 signaling in rat pheochromocytoma PC12 cells . Although autophagy is a highly regulated cellular process , its relevance to cancer seems to be complicated . It is of note that inhibition of mTORC1 is a prerequisite for autophagy induction . Indeed , direct mTORC1 inhibition initiates ULK1/2 autophosphorylation and subsequent Atg13 and FIP200 phosphorylation , inducing autophagy . Here , we demonstrated that sunitinib significantly increased the levels of LC3-II , concomitant with a decrease of p62 in PC12 cells . Following sunitinib treatment , immunofluorescent imaging revealed a marked increased punctate LC3-II distribution . Furthermore , Atg13 knockdown significantly reduced its protein level , which in turn abolished sunitinib-induced autophagy . Moreover , inhibition of autophagy by siRNAs targeting Atg13 or by pharmacological inhibition with ammonium chloride , enhanced both sunitinib-induced apoptosis and anti-proliferation . Thus , sunitinib-induced autophagy is dependent on the suppression of mTORC1 signaling and the formation of ULK1/2-Atg13-FIP200 complexes . Inhibition of autophagy may be a promising therapeutic option for improving the anti-tumor effect of sunitinib . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: ABSTRACT : BACKGROUND : The ubiquitin-proteasome system and macroautophagy ( hereafter referred to autophagy ) are two complementary pathways for protein degradation . Emerging evidence suggests that proteasome inhibition might be a promising approach for tumor therapy . Accumulating data suggest that autophagy is activated as a compensatory mechanism upon proteasome activity is impaired . METHOD : Autophagy activation was measured using acridine orange staining and LC3 transition . Cell viability and apoptosis were measured using MTT assay and flow cytometry , respectively . Beclin 1 expression vectors or shRNA against Beclin 1 ( shBeclin 1 ) were transfected to investigate the role of Beclin 1 in autophagy activation and cytotoxicity of ovarian cancer cells induced by proteasome inhibitors . RESULTS : Proteasome inhibitors suppressed proliferation and induced autophagy in ovarian cancer cells . Neither phosphoinositide 3-kinase ( PI3K ) inhibitors nor shRNA against Beclin 1 could abolish the formation of acidic vacuoles and the processing of LC3 induced by proteasome inhibitors . Moreover , Beclin 1 overexpression enhanced anti-proliferative effects of proteasome inhibitors in ovarian cancer cells . CONCLUSIONS : For the first time , the current study demonstrated that proteasome inhibitors induced PI3K and Beclin 1-independent autophagy in ovarian cancer cells . In addition , this study revealed autophagy-independent tumor suppressive effects of Beclin 1 in ovarian cancer cells . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Recently , our group reported the discovery of three new withanolides , physangulidines A-C , from Physalis angulata . In this study , the biological effects of physangulidine A ( 1 ) , which was the most active and abundant of the three new constituents , are described . It was found that 1 significantly reduces survival in clonogenic assays for two hormone-independent prostate cancer cell lines . Flow cytometry and confocal microscopy studies in DU145 human prostate cancer cells indicated that 1 induces cell cycle arrest in the G(2)/M phase and causes defective mitosis . It was determined also that 1 produces programed cell death by apoptosis , as evidenced by biochemical markers and distinct changes in cell morphology . These results imply that the antimitotic and proapoptotic effects of 1 may contribute significantly to the biological activities and potential medicinal properties of its plant of origin . OUTPUT:

Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The evidence that androgen blockade-resistant prostate cancer , termed castration resistant , remains androgen receptor ( AR ) dependent is compelling . AR is re-activated through multiple mechanisms including expression of constitutively active splice variants that lack hormone binding domains ( HBDs ) . This highlights need to develop therapies that target regions other than the HBD . Because the p160 coactivators interact most strongly with the amino-terminus of AR , we examined the consequences of disrupting this interaction . We identified two overlapping SRC-1 peptides that interact with AR , but not with progesterone receptor . These peptides reduce AR and AR variant AR-V7 dependent induction of an AR responsive reporter . Using mammalian two hybrid assays , we found that the peptides interrupt the AR/SRC-1 , AR/SRC-2 and AR N/C interactions , but not SRC-1/CARM-1 interactions . Consistent with the SRC-1 dependence of induced , but not repressed genes , in LNCaP cells , the peptides inhibited hormone dependent induction of endogenous target genes including PSA and TMPRSS2 , but did not block AR dependent repression of UGT2B17 or inhibit vitamin D receptor activity . Simultaneous detection of SRC-1 peptides and PSA by double immunofluorescence in transfected LNCaP cells clearly demonstrated a strong reduction in PSA levels in cells expressing the peptides . The peptides also inhibited the AR dependent expression of PSA in castration resistant C4-2 cells . Moreover they inhibited androgen dependent proliferation of LNCaP cells and proliferation of C4-2 cells in androgen depleted medium without affecting AR negative PC-3 cells . Thus , the p160 coactivator binding site is a novel potential therapeutic target to inhibit AR activity . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: AIM : To explore the inhibitory effect of sulfated polysaccharide from Masson pine ( Pinus massoniana ) pollen ( SPPM60 ) on G(2)/M phase of human liver cancer HepG2 cells and its mechanism . METHODS : The proliferation rate of HepG2 cells was evaluated by methyl thiazolyl tetrazolium ( MTT ) colorimetric assay . The cycles of HepG2 cells were measured by flow cytometry when 200μg/ml concentration of SPPM60 was adopted , the expression of the genes related to cell cycle was detected by real-time PCR . RESULTS : SPPM60 inhibited the proliferation of HepG2 cells and the inhibition rate was elevated with increase of SPPM60 concentration . After treatment with 200μg/ml of SPPM60 , the percentage of S phase cells was decreased , but that of G(2)/M phase was significantly increased ( 72h vs control : 32.96�0.33% vs 18.59�0.04% , 3.44�0.05% vs 18.30�0.08% , P<0.01 ) . The results of real-time PCR showed that SPPM60 could down-regulate the mRNA levels of CDK1 and CyclinB ( P<0.01 ) , and up-regulate the expression of p53 and p21 ( P<0.05 ) . CONCLUSION : SPPM60 causes arrest of HepG2 cells at G(2)/M phase , and the mechanism is related to the down-regulation of CDK1 and CyclinB and up-regulation of p53 and p21 expression . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: MicroRNAs ( miRNAs ) are involved in cancer development and progression , acting as tumor suppressors or oncogenes . In this study , miRNA profiling was performed on 10 paired bladder cancer ( BC ) tissues using 20 GeneChipTM miRNA Array , and 10 differentially expressed miRNAs were identified in BC and adjacent noncancerous tissues of any disease stage/grade . After validated on expanded cohort of 67 paired BC tissues and 10 human BC cell lines by qRT-PCR , it was found that miR-100 was down-regulated most significantly in cancer tissues . Ectopic restoration of miR-100 expression in BC cells suppressed cell proliferation and motility , induced cell-cycle arrest in vitro , and inhibited tumorigenesis in vivo both in subcutaneous and intravesical passage . Bioinformatic analysis showed that mTOR gene was a direct target of miR-100. siRNA-mediated mTOR knockdown phenocopied the effect of miR-100 in BC cell lines . In addition , the cancerous metastatic nude mouse model established on the basis of primary BC cell lines suggested that miR-100/mTOR regulated cell motility and was associated with tumor metastasis . Both mTOR and p70S6K ( downstream messenger ) presented higher expression levels in distant metastatic foci such as in liver and kidney metastases than in primary tumor . Taken together , miR-100 may act as a tumor suppressor in BC , and reintroduction of this mature miRNA into tumor tissue may prove to be a therapeutic strategy by reducing the expression of target genes .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Diffuse intrinsic pontine glioma ( DIPG ) is a fatal pediatric disease . Thus far no therapeutic agent has proven beneficial in the treatment of this malignancy . Hence , conventional DNA-damaging radiotherapy ( RT ) remains the standard treatment , providing transient neurological improvement without improving probability of overall survival . During RT , WEE1 kinase controls the G2 cell cycle checkpoint allowing for repair of irradiation ( IR)-induced DNA damage . Here we show that WEE1 kinase is one of the highest overexpressed kinases in primary DIPG tissues as compared to matching non-neoplastic brain tissues . Inhibition of WEE1 by MK-1775 treatment of DIPG cells inhibited the IR-induced WEE1-mediated phosphorylation of CDC2 , resulting in reduced G2/M arrest and decreased cell viability . Finally , we demonstrate that MK-1775 enhances the radiation response of E98-Fluc-mCherry DIPG mouse xenografts . Altogether , these results show that inhibition of WEE1 kinase in conjunction with RT holds potential as a therapeutic approach for the treatment of DIPG . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: OBJECTIVES : Cigarette smoking is a major risk factor for pancreatic cancer ( PaCa ) . However , the mechanisms of smoking-induced PaCa remain unknown . Here we investigated the effect of smoking compounds on cell death pathways in pancreatic ductal cells , precursors of PaCa . METHODS : Human pancreatic ductal cells ( HPDE6-c7 ) were cultured with cigarette smoke extract ( CSE ) or smoking compound 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone ( NNK ) . Apoptosis and autophagy were assessed by DNA fragmentation and immunofluorescence , respectively . RESULTS : Exposure to CSE or NNK decreased DNA fragmentation and up-regulated BclXL . Akt kinase was activated by smoking compounds through reactive oxygen species-dependent mechanism . Specifically , Akt activation was prevented by inhibition of nicotinamide adenine dinucleotide oxidase . Molecular or pharmacologic inhibitions of Akt prevented the antiapoptotic effect of smoking compounds . Smoking compounds stimulated rapid ( 1 hour ) and transient activation of 5'-adenosine monophosphate-activated protein kinase and formation of autophagic vacuoles , indicating stimulation of autophagy . Repeated exposure to CSE/NNK ( 48 hours or longer ) abolished the early activation of autophagic markers . Inhibition of Akt prevented the antiautophagic effect of long exposure to smoking compounds , indicating that smoking-induced late activation of Akt prevents autophagy . CONCLUSIONS : Long exposure of pancreatic ductal cells to smoking compounds inhibited apoptosis and autophagy . The results revealed a central role for Akt kinase in mediating key procarcinogenic effects of smoking compounds . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Most hepatocellular carcinomas ( HCC ) develop in the context of severe liver fibrosis and cirrhosis caused by chronic liver inflammation , which also results in accumulation of reactive oxygen species ( ROS ) . In this study , we examined whether the stress-activated protein kinase p38α ( Mapk14 ) controls ROS metabolism and development of fibrosis and cancer in mice given thioacetamide to induce chronic liver injury . Liver-specific p38α ablation was found to enhance ROS accumulation , which appears to be exerted through the reduced expression of antioxidant protein HSP25 ( Hspb1 ) , a mouse homolog of HSP27 . Its reexpression in p38α-deficient liver prevents ROS accumulation and thioacetamide-induced fibrosis. p38α deficiency increased expression of SOX2 , a marker for cancer stem cells and the liver oncoproteins c-Jun ( Jun ) and Gankyrin ( Psmd10 ) and led to enhanced thioacetamide-induced hepatocarcinogenesis . The upregulation of SOX2 and c-Jun was prevented by administration of the antioxidant butylated hydroxyanisole . Intriguingly , the risk of human HCC recurrence is positively correlated with ROS accumulation in liver . Thus , p38α and its target HSP25/HSP27 appear to play a conserved and critical hepatoprotective function by curtailing ROS accumulation in liver parenchymal cells engaged in oxidative metabolism of exogenous chemicals . Augmented oxidative stress of liver parenchymal cells may explain the close relationship between liver fibrosis and hepatocarcinogenesis . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Each year , more than 700,000 people undergo cancer surgery in the United States . However , more than 40% of those patients develop recurrences and have a poor outcome . Traditionally , the medical community has assumed that recurrent tumors arise from selected tumor clones that are refractory to therapy . However , we found that tumor cells have few phenotypical differences after surgery . Thus , we propose an alternative explanation for the resistance of recurrent tumors . Surgery promotes inhibitory factors that allow lingering immunosuppressive cells to repopulate small pockets of residual disease quickly . Recurrent tumors and draining lymph nodes are infiltrated with M2 ( CD11b(+)F4/80(hi)CD206(hi) and CD11b(+)F4/80(hi)CD124(hi) ) macrophages and CD4(+)Foxp3(+) regulatory T cells . This complex network of immunosuppression in the surrounding tumor microenvironment explains the resistance of tumor recurrences to conventional cancer vaccines despite small tumor size , an intact antitumor immune response , and unaltered cancer cells . Therapeutic strategies coupling antitumor agents with inhibition of immunosuppressive cells potentially could impact the outcomes of more than 250,000 people each year . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Chromosomal DNA must be in single-strand form for important transactions such as replication , transcription , and recombination to occur . The single-strand DNA ( ssDNA ) is more prone to damage than double-strand DNA ( dsDNA ) , due to greater exposure of chemically reactive moieties in the nitrogenous bases . Thus , there can be agents that damage regions of ssDNA in vivo while being inert toward dsDNA . To assess the potential hazard posed by such agents , we devised an ssDNA-specific mutagenesis reporter system in budding yeast . The reporter strains bear the cdc13-1 temperature-sensitive mutation , such that shifting to 37°C results in telomere uncapping and ensuing 5 ' to 3 ' enzymatic resection . This exposes the reporter region , containing three closely-spaced reporter genes , as a long 3 ' ssDNA overhang . We validated the ability of the system to detect mutagenic damage within ssDNA by expressing a modified human single-strand specific cytosine deaminase , APOBEC3G . APOBEC3G induced a high density of substitutions at cytosines in the ssDNA overhang strand , resulting in frequent , simultaneous inactivation of two reporter genes . We then examined the mutagenicity of sulfites , a class of reactive sulfur oxides to which humans are exposed frequently via respiration and food intake . Sulfites , at a concentration similar to that found in some foods , induced a high density of mutations , almost always as substitutions at cytosines in the ssDNA overhang strand , resulting in simultaneous inactivation of at least two reporter genes . Furthermore , sulfites formed a long-lived adducted 2'-deoxyuracil intermediate in DNA that was resistant to excision by uracil-DNA N-glycosylase . This intermediate was bypassed by error-prone translesion DNA synthesis , frequently involving Pol ζ , during repair synthesis . Our results suggest that sulfite-induced lesions in DNA can be particularly deleterious , since cells might not possess the means to repair or bypass such lesions accurately . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: The ATM/ATR DNA damage checkpoint functions in the maintenance of genetic stability and some missense variants of the ATM gene have been shown to confer a moderate increased risk of prostate cancer . However , whether inactivation of this checkpoint contributes directly to prostate specific cancer predisposition is still unknown . Here , we show that exposure of non-malignant prostate epithelial cells ( HPr-1AR ) to androgen led to activation of the ATM/ATR DNA damage response and induction of cellular senescence . Notably , knockdown of the ATM gene expression in HPr-1AR cells can promote androgen-induced TMPRSS2 : ERG rearrangement , a prostate-specific chromosome translocation frequently found in prostate cancer cells . Intriguingly , unlike the non-malignant prostate epithelial cells , the ATM/ATR DNA damage checkpoint appears to be defective in prostate cancer cells , since androgen treatment only induced a partial activation of the DNA damage response . This mechanism appears to preserve androgen induced autophosphorylation of ATM and phosphorylation of H2AX , lesion processing and repair pathway yet restrain ATM/CHK1/CHK2 and p53 signaling pathway . Our findings demonstrate that ATM/ATR inactivation is a crucial step in promoting androgen-induced genomic instability and prostate carcinogenesis . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Prostate cancer is the most frequent and second most lethal cancer in men in the United States . Innate immunity and inflammation may increase the risk of prostate cancer . To determine the role of innate immunity and inflammation in advanced prostate cancer , we investigated the association of 320 single nucleotide polymorphisms , located in 46 genes involved in this pathway , with disease risk using 494 cases with advanced disease and 536 controls from Cleveland , Ohio . Taken together , the whole pathway was associated with advanced prostate cancer risk ( P = 0.02 ) . Two sub-pathways ( intracellular antiviral molecules and extracellular pattern recognition ) and four genes in these sub-pathways ( TLR1 , TLR6 , OAS1 , and OAS2 ) were nominally associated with advanced prostate cancer risk and harbor several SNPs nominally associated with advanced prostate cancer risk . Our results suggest that the innate immunity and inflammation pathway may play a modest role in the etiology of advanced prostate cancer through multiple small effects . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Ulcerative colitis ( UC ) is a major form of chronic inflammation that can frequently progress to colon cancer . Several studies have demonstrated massive infiltration of neutrophils and macrophages into the lamina propria and submucosa in the progression of UC-associated colon carcinogenesis . Macrophages contribute to the development of colitis-associated colon cancer ( CAC ) . However , the role of neutrophils is not well understood . To better understand the involvement of tumor-associated neutrophils ( TANs ) in the regulation of CAC , we used a mouse CAC model produced by administering azoxymethane ( AOM ) , followed by repeated dextran sulfate sodium ( DSS ) ingestion . This causes severe colonic inflammation and subsequent development of multiple tumors in mice colon . We observed that colorectal mucosal inflammation became increasingly severe with AOM and DSS treatment . Macrophages infiltrated the lamina propria and submucosa , together with a marked increase in neutrophil infiltration . The chemokine CXCL2 increased in the lamina propria and submucosal regions of the colons of the treated mice , together with the infiltration of neutrophils expressing CXCR2 , a specific receptor for CXCL2 . This process was followed by neoplastic transformation . After AOM and DSS treatment , the mice showed enhanced production of metalloproteinase ( MMP)-9 and neutrophil elastase ( NE ) , accompanied by excessive vessel generation and cell proliferation . Moreover , CXCL2 promoted neutrophil recruitment and induced neutrophils to express MMP-9 and NE in vitro . Furthermore , administration of neutrophil-neutralizing antibodies after the last DSS cycle markedly reduced the number and size of tumors and decreased the expression of CXCR2 , CXCL2 , MMP-9 , and NE . These observations indicate a crucial role for TANs in the initiation and progression of CAC and suggest that the CXCL2-CXCR2 axis might be useful in reducing the risk of UC-associated colon cancer .

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Cellular senescence is considered as a tumor suppressive mechanism . Recent evidence indicates however that senescent cells secrete various growth factors and cytokines , some of which may paradoxically promote cancer progression . This phenomenon termed senescence-associated secretory phenotype ( SASP ) must be inhibited in order for anti-proliferative agents to be effective . The present study was designed to determine whether the β-catenin destruction complex ( BCDC ) , known to integrate the action of various growth factors and cytokines , would represent a suitable target to inhibit the activity of SASP components . For this , we carried out experiments to determine the effect of drug-induced senescence on secretion of SASP , β-catenin transactivation , and the relationship between these processes . Moreover , genetic and pharmacological approaches were used to define the implication of BCDC in mediating the effects of SASP components on cell migration and resistance to drugs . The findings indicate that drug-induced senescence was associated with expression of various Wnt ligands in addition to previously known SASP components . Beta catenin transactivation and expression of genes implicated in epithelial-mesenchymal transition ( EMT ) also increased in response to drug-induced SASP . These effects were prevented by Pyrvinium , a recently described activator of BCDC . Pyrvinium also suppressed the effects of SASP on cell migration and resistance to doxorubicin . Together , these findings provide insights on the potential role of BCDC in mediating the effects of drug-induced SASP on cancer cell invasion and resistance to therapy , and suggest that targeting this pathway may represent an effective approach to enhance the activity of current and prospective anti-cancer therapeutics .

The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics. ### INPUT: Breast cancer is the most commonly diagnosed cancer in women in the world and is one of the leading causes of death due to cancer . Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis. OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Binding within or nearby target genes involved in cell proliferation and survival enables the p53 tumor suppressor gene to regulate their transcription and cell-cycle progression . Using genome-wide chromatin-binding profiles , we describe binding of p53 also to regions located distantly from any known p53 target gene . Interestingly , many of these regions possess conserved p53-binding sites and all known hallmarks of enhancer regions . We demonstrate that these p53-bound enhancer regions ( p53BERs ) indeed contain enhancer activity and interact intrachromosomally with multiple neighboring genes to convey long-distance p53-dependent transcription regulation . Furthermore , p53BERs produce , ina p53-dependent manner , enhancer RNAs ( eRNAs ) that are required for efficient transcriptional enhancement of interacting target genes and induction of a p53-dependent cell-cycle arrest . Thus , our results ascribe transcription enhancement activity to p53 with the capacity to regulate multiple genes from a single genomic binding site . Moreover , eRNA production from p53BERs is required for efficient p53 transcription enhancement . OUTPUT:

OUTPUT: sustaining proliferative signaling;resisting cell death INPUT: Jaceosidin , a flavonoid derived from Artemisia princeps ( Japanese mugwort ) , has been shown to inhibit the growth of several human cancer cells , However , the exact mechanism for the cytotoxic effect of jaceosidin is not completely understood . In this study , we investigated the molecular mechanism involved in the antiproliferative effect of jaceosidin in human endometrial cancer cells . We demonstrated that jaceosidin is a more potent inhibitor of cell growth than cisplatin in human endometrial cancer cells . In contrast , jaceosidin-induced cytotoxicity in normal endometrial cells was lower than that observed for cisplatin . Jaceosidin induced G2/M phase cell cycle arrest and modulated the levels of cyclin B and p-Cdc2 in Hec1A cells . Knockdown of p21 using specific siRNAs partially abrogated jaceosidin-induced cell growth inhibition . Additional mechanistic studies revealed that jaceosidin treatment resulted in an increase in phosphorylation of Cdc25C and ATM-Chk1/2 . Ku55933 , an ATM inhibitor , reversed jaceosidin-induced cell growth inhibition , in part . Moreover , jaceosidin treatment resulted in phosphorylation of ERK , and pretreatment with the ERK inhibitor , PD98059 , attenuated cell growth inhibition by jaceosidin . These data suggest that jaceosidin , isolated from Japanese mugwort , modulates the ERK/ATM/Chk1/2 pathway , leading to inactivation of the Cdc2-cyclin B1 complex , followed by G2/M cell cycle arrest in endometrial cancer cells .
