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.\n OUTPUT: sustaining proliferative signaling;resisting cell death\n\n INPUT: The main feedback loop driving circadian rhythm in mice is controlled , in part , by the genes encoding the cryptochromes Cry1 and Cry2 . Targeted mutation of both Cry1 and Cry2 delay the early onset of tumor formation in p53-null mutant mice . Furthermore , Ras-transformed p53- and Cry-null mouse skin fibroblasts are more sensitive than p53 mutants to apoptotic cell death initiated by agents that activate either the intrinsic or the extrinsic apoptosis pathways . Here , we investigated the effect of Cry1 and Cry2 mutations on cell death by other genotoxic agents that generate alkylated bases , interstrand crosslinks , DNA-protein crosslinks , and double-strand breaks . Both ultraviolet ( UV ) and the UV mimetic compound oxaliplatin and the radiomimetic compound doxorubicin promoted apoptosis by upregulating the tumor suppressor p73 . However , only the UV and oxaliplatin-induced upregulation of p73 mediated by the transcription factor Egr1 , but not the doxorubicin-induced upregulation mediated by the transcription factor E2F1 , was enhanced by Cry1/Cry2 double mutation . Accordingly , Egr1 downregulation reduced oxaliplatin-induced apoptosis , whereas E2F1 downregulation reduced doxorubicin-induced apoptosis . Our findings establish distinct roles for cryptochromes in intrinsic apoptosis induced by UV mimetic and radiomimetic agents .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;genomic instability and mutation" } ]

It is a long lasting question how DNA repair is spatially and temporarily organized in the highly compartmentalized nucleus and whether the diverse nuclear compartments regulate differently the efficiency of repair . Increasing evidence suggest the involvement of nuclear pore complexes in repair of double-strand breaks ( DSBs ) in yeast . Here , we show that the human nucleoporin 153 ( NUP153 ) has a role in repair of DSBs and in the activation of DNA damage checkpoints . We explore the mechanism of action of NUP153 and we propose its potential as a novel therapeutic target in cancers .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

It is non-endocrine neoplasm of the anterior pituitary that occurs in adults and usually follows a benign clinical course , corresponding to WHO grade I. Up to now , pituitary SCO have been reported occasionally and only 14 cases of SCO have been documented in the literature . Because of their rarity , the pathogenesis and natural history of these tumours have not been fully characterized . We report two additional cases of SCO occurring in females aged 63 years ( Case 1 ) and 65 years ( Case 2 ) , who presented with pan-hypopituitarism , headache and visual field defect . In both cases , the magnetic resonance imaging showed solid sellar mass of moderate size with suprasellar extension . The clinical and radiological features suggested non-functioning pituitary macroadenomas without evidence of invasive growth . One patient presented with tumour recurrence 3 years after undergoing the previous surgical removal of tumour , which was initially misdiagnosed as schwannoma . The first tumour was removed by transsphenoidal surgery and the second one by frontal craniotomy . Histologically and immunohistochemically , both tumours displayed the features typical for SCO of the pituitary . They were composed of interwoven fascicles of spindle cells exhibiting abundant eosinophilic cytoplasm of oncocytic or granular appearance . Mitoses were rarely observed and necrosis was absent . In one case , the advanced lymphocytic infliltration was observed within neoplastic tissue . The tumour cells exhibited immunoreactivity for S-100 protein , galectin-3 , vimentin and epithelial membrane antigen but they were negative for GFAP , anterior pituitary neuroendocrine markers ( prolactin , growth hormone , TSH , ACTH , FSH , LH ) , chromogranin , synaptophysin , cytokeratin CK ( AE1/AE3 ) , smooth muscle actin , desmin , CD34 and CD68 . MIB1 labeling index did not exceed 10% . Ultrastructurally , the tumour cells were rich in mitochondria with lamellar cristae . Moreover , in Case 2 some tumour cells showed a number of giant mitochondria with severely destructed internal matrix . Spindle cell oncocytoma of the anterior pituitary is often misdiagnosed entity of uncertain histogenesis . It should be considered in the differential diagnosis of various sellar-region lesions of oncocytic morphology .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

We observed promoter methylation and loss of expression in neurofilament heavy polypeptide ( NEFH ) in a significant proportion of primary esophageal squamous cell carcinoma ( ESCC ) samples that were of a high tumor grade and advanced stage . RNA interference-mediated knockdown of NEFH accelerated ESCC cell growth in culture and increased tumorigenicity in vivo , whereas forced expression of NEFH significantly inhibited cell growth and colony formation . Loss of NEFH caused up-regulation of pyruvate kinase-M2 type and down-regulation of pyruvate dehydrogenase , via activation of the Akt/beta-catenin pathway , resulting in enhanced aerobic glycolysis and mitochondrial dysfunction . The acceleration of glycolysis and mitochondrial dysfunction in NEFH-knockdown cells was suppressed in the absence of beta-catenin expression , and was decreased by the treatment of 2-Deoxyglucose , a glycolytic inhibitor , or API-2 , an Akt inhibitor . Loss of NEFH activates the Akt/beta-catenin pathway and increases glycolysis and mitochondrial dysfunction . Cancer cells with methylated NEFH can be targeted for destruction with specific inhibitors of deregulated downstream pathways .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

In 23 patients , the predominant operative finding was hemorrhage with or without necrosis . However , there were 15 ( 37.7% ) cases where pale , necrotic tissue with no evidence of hemorrhage was found at surgery . Pale , necrotic material was particularly found when there was a long interval between the acute clinical event and surgery . It is concluded that the pale , necrotic debris represents one stage in the resorption process of blood after hemorrhagic necrosis of pituitary adenomas .

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;genomic instability and mutation" } ]

There is an urgent need to identify new molecular targets for the development of novel therapeutic approaches . Herein , we review the structure , function and biology of glypican-3 ( GPC3 ) and its role in human cancer with a focus on its potential as a therapeutic target for immunotherapy . GPC3 is a cell-surface protein that is over-expressed in HCC . Loss-of-function mutations of GPC3 cause Simpson-Golabi-Behmel syndrome ( SGBS ) , a rare X-linked overgrowth condition . GPC3 binds Wnt and Hedgehog ( Hh ) signalling proteins . GPC3 is also able to bind basic growth factors such as fibroblast growth factor 2 through its heparan sulphate glycan chains . GPC3 is a promising candidate for liver cancer therapy given that it shows high expression in HCC . An anti-GPC3 monoclonal antibody has shown anti-cancer activity in mice and its humanised IgG molecule is currently undergoing clinical evaluation in patients with HCC .

The purpose of this study was to determine the effects of adenovirus-mediated MMAC/PTEN expression on the growth and survival of human esophageal cancer cells in vitro and in vivo . We found that compared to control cells , overexpression of PTEN significantly suppressed growth and induced apoptosis in esophageal cancer cell lines Eca-109 and TE-1 via downregulation of Bcl-2 expression and changes in cell-cycle progression . Adenovirus PTEN also inhibited the growth of subcutaneous tumor xenografts by significantly reducing tumor size in vivo . Thus our results confirm the proposed functional role of MMAC/PTEN as a regulator of esophageal cancer progression in vivo and in vitro .

INK4a and ARF are distinct proteins encoded by transcripts in which a shared exon is decoded in alternative reading frames . Here we analyze dermal fibroblasts ( designated Q34 ) from an individual carrying independent missense mutations in each copy of the common exon . Both mutations alter the amino acid sequence of INK4a and functionally impair the protein , although they do so to different degrees . Only one of the mutations affects the sequence of ARF , causing an apparently innocuous change near its carboxy terminus . Unlike normal human fibroblasts , Q34 cells are not permanently arrested by Ras or its downstream effectors Ets1 and Ets2 . Moreover , ectopic Ras enables the cells to grow as anchorage-independent colonies , and in relatively young Q34 cells anchorage independence can be achieved without addition of telomerase or perturbation of the p53 pathway . Whereas ARF plays the principal role in Ras-induced arrest of mouse fibroblasts , our data imply that INK4a assumes this role in human fibroblasts .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Angiogenesis and the PDGFR pathway could be potential therapeutic targets . This study aimed to screen ependymomas for the expression and clinicopathological correlates of angiogenic factors and potential therapeutic targets including VEGFR , endoglin ( CD105 ) , CD34 , CD31 , c-Kit , PDGFR-α and PDGFR-β . Immunohistochemistry for angiogenesis factors and PDGFR-α and β was performed in 24 archival tumor samples from children and adults treated for ependymoma at our institution . CD31 density , CD105 density and pericyte coverage index ( PCI ) were calculated . These findings were correlated with clinical outcome . VEGFR2 was overexpressed in tumor cells in only one out of 24 cases , but was found overexpressed in the vessels in 6 cases . PDGFR-α and β were found to be over-expressed in the ependymoma tumor cells in seven out of 24 cases ( 29.2 % ) . CD31 density , CD105 density and PCI did not correlate with expression of PDGFRs . Overexpression of PDGFR-α and β in tumor cells and overexpression of PDGFR-α in tumor endothelium had prognostic significance and this was maintained in multivariate analysis for overexpression of PDGFR-α in tumor cells ( 2 year progression free survival was 16.7 ± 15.2 for cases with overexpression of PDGFR-α in the tumor vs. 74.5 ± 15.2 for those with low/no expression , hazard ratio = 5.78 , p = 0.04 ) . A number of angiogenic factors are expressed in ependymoma tumor cells and tumor endothelium . Preliminary evidence suggests that the expression of PDGFRs could have a prognostic significance in ependymoma . This data suggests that PDGFRs should be further evaluated as targets using novel PDGFR inhibitors .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

In this context , heparan sulfate proteoglycans ( HSPGs ) emerge as interesting targets , owing to their function as co-receptors of major , pro-angiogenic factors . Accordingly , previous studies have suggested anti-tumor effects of heparin , i.e. over-sulfated HS , and various heparin mimetics ; however , a significant drawback is their unspecific mechanism of action and potentially serious side-effects related to their anticoagulant properties . Here , we have explored the use of human ScFv anti-HS antibodies ( αHS ) as a more rational approach to target HSPG function in endothelial cells ( ECs). αHS were initially selected for their recognition of HS epitopes localized preferentially to the vasculature of patient glioblastoma tumors , i.e. highly angiogenic brain tumors . Unexpectedly , we found that these αHS exhibited potent pro-angiogenic effects in primary human ECs. αHS were shown to stimulate EC differentiation , which was associated with increased EC tube formation and proliferation . Moreover , αHS supported EC survival under hypoxia and starvation , i.e. conditions typical of the tumor microenvironment . Importantly , αHS-mediated proliferation was efficiently counter-acted by heparin and was absent in HSPG-deficient mutant cells , confirming HS-specific effects . On a mechanistic level , binding of αHS to HSPGs of ECs as well as glioblastoma cells was found to trigger p38 MAPK-dependent signaling resulting in increased proliferation . We conclude that several αHS that recognize HS epitopes abundant in the tumor vasculature may elicit a pro-angiogenic response , which has implications for the development of antibody-based targeting of HSPGs in cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;inducing angiogenesis" } ]

Starting at 6 weeks of age , a total of 37 male ACI/N rats were divided into two groups and treated as follows : group I ( 18 rats ) received diet containing 1% 1-HA for 12 months ; group II ( 19 rats ) was given the basal diet alone . Sub-groups of 5-7 rats were sequentially killed at 4 , 8 and 12 months for evaluation of the length , cell numbers and 5-bromo-2'-deoxyuridine ( BrDU ) labeling indices of large bowel crypts together with ODC activity . All kinetic and ODC data indicated increased DNA synthesis and proliferation at all time points . Morphological observation of the intestines also revealed melanosis , crypt abscesses and erosion , becoming more pronounced with length of exposure to the anthraquinone . The data thus suggest that cell proliferation in the crypts of the cecum or colon is important for 1-HA-induced intestinal carcinogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

The toxic environmental pollutant , 1 , 2-dimethylhydrazine ( DMH ) , is also a colon-specific carcinogen . Tannic acid ( TA ) is reported to be effective against various types of chemically induced toxicity and also carcinogenesis . In the present study , we evaluated the chemopreventive efficacy of TA against DMH induced colon toxicity in a rat model . Efficacy of TA against the colon toxicity was evaluated in terms of biochemical estimation of antioxidant enzyme activities , lipid peroxidation , histopathological changes and expression of early molecular markers of inflammation and tumor promotion . DMH treatment induced oxidative stress enzymes ( p<0.001 ) and an early inflammatory and tumor promotion response in the colons of Wistar rats . TA treatment prevented deteriorative effects induced by DMH through a protective mechanism that involved reduction of oxidative stress as well as COX-2 , i-NOS , PCNA protein expression levels and TNF-α(p<0.001) release . It could be concluded from our results that TA markedly protects against chemically induced colon toxicity and acts plausibly by virtue of its antioxidant , anti-inflammatory and antiproliferative activities .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

VIP has previously been shown in our laboratory to cause the in vitro growth inhibition and morphological differentiation of the human neuroblastoma cell line , LA-N-5 . It is now shown that LA-N-5 cells express immunoreactive VIP and bear specific VIP receptors . Antagonism of endogenous VIP , either by competitive inhibition or receptor blockade , increased cell proliferation , suggesting that VIP is operative in normal growth regulation . Intracellular and extracellular levels of VIP were also shown to increase significantly during the retinoic acid-induced differentiation of these cells . Furthermore , a concomitant marked increase in VIP receptor expression was demonstrated with cellular differentiation . These receptors remain functional as evidenced by a matching increase in the level of detectable cAMP generated in response to exogenous VIP . It is concluded that VIP is a normal autoregulator of neuroblastoma cell growth and differentiation , and that retinoic acid-mediated differentiation may be , in part , due to endogenous VIP .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;resisting cell death" } ]

Telomerase can repetitively reverse transcribe its short RNA template , acting processively to add multiple telomeric repeats onto the same DNA substrate . The contribution of enzyme processivity to telomere length regulation in human cells is not well characterized . In cancer cells , under homeostatic telomere length-maintenance conditions , telomerase acts processively , while under nonequilibrium conditions , telomerase acts distributively on the shortest telomeres . To investigate the role of increased telomerase processivity on telomere length regulation in human cells with limited lifespan that are dependent on human TERT ( hTERT ) for lifespan extension and immortalization , we mutated the leucine at position 866 in the reverse transcriptase C motif of hTERT to a tyrosine ( L866Y ) , which is the amino acid found at a similar position in HIV-1 reverse transcriptase . We report that , similar to the previously reported ' gain of function ' Tetrahymena telomerase mutant ( L813Y ) , the human telomerase variant displays increased processivity. hTERT-L866Y , like wild-type hTERT can immortalize and extend the lifespan of limited lifespan cells . Moreover , hTERT-L866Y expressing cells display heterogenous telomere lengths , telomere elongation , multiple telomeric signals indicative of fragile sites and replicative stress , and an increase in short telomeres , which is accompanied by telomere trimming events .

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

We here present a novel angiogenesis marker , microvessel proliferation ( MVP ) , based on dual immunohistochemical staining of nestin and Ki-67 . Immature endothelial cells express nestin , and when co-expressed with the proliferation marker Ki-67 , the number of proliferating immature blood vessels can be measured . MATERIALS AND METHODS : Microvessel proliferation was evaluated in 178 breast cancer samples and estimated by vascular proliferation index ( VPI ) , the ratio between the number of vessels containing proliferating endothelial cells and the total number of immature vessels . RESULTS : High VPI was strongly associated with several markers of aggressive breast cancer , such as negative oestrogen receptor ( ER ) status ( p=0.003 ) , high tumour cell proliferation by Ki-67 ( p=0.004 ) , high p53 expression ( p=0.001 ) , and five profiles for the basal-like phenotype ( odds ratios ( OR ) ; range 3.4-6.3 ) . Also , high VPI was significantly associated with interval detected breast cancer compared with screening detected lesions ( p<0.0005 ) , and adverse outcome in univariate and multivariate survival analysis ( p=0.034 and p=0.022 , respectively ) .

Here we show that treatment of rhabdoid tumor derived G401 cells with a nucleolin antagonist , the HB-19 pseudopeptide , could restore contact inhibition , impair anchorage-independent growth , and suppress tumor development in nude mice . G401 cells grow without contact inhibition , which is an in vitro characteristic property of malignant tumor cells . At concentrations of HB-19 that does not affect cell viability and multiplication index , there is restoration of contact inhibition thus suggesting that HB-19 treatment causes reversion of the malignant phenotype . Accordingly , HB-19 pretreated G401 cells lose the capacity to form colonies in soft agar . When assayed for tumorigenicity in nude mice , only 50% of mice injected with HB-19 pretreated G401 cells developed tumors with the mean tumor weight of 0.32 g , compared to 100% of mice injected with control G401 cells with the mean tumor weight of 2.36 g . Interestingly , the restoration of contact inhibition in HB-19 treated G401 cells is concomitant with marked reduction of transcripts coding the Wilms ' tumor 1 gene , matrix metalloproteinase-2 , epithelial isoform of CD44 , and vascular endothelial growth factor , whereas no apparent modification is detected for transcripts coding the proto-oncogene c-Myc , anti-apoptotic Bcl-2 , pro-apoptotic Bax , tissue inhibitor of metalloproteinase TIMP-1 , angiogenesis inhibitor TSP-1 , and growth factor Midkine . These findings indicate that the molecular mechanism of action of HB-19 on such highly malignant rhabdoid tumor cells is associated with a selective inhibitory effect on the expression of genes implicated in tumorigenesis and angiogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

In this model , glycolytic stromal cells produce mitochondrial fuels ( L-lactate and ketone bodies ) that are then transferred to oxidative epithelial cancer cells , driving OXPHOS and mitochondrial metabolism . Thus , stromal catabolism fuels anabolic tumor growth via energy transfer . We have termed this new cancer paradigm the \" reverse Warburg effect, \" because stromal cells undergo aerobic glycolysis , rather than tumor cells . To assess whether this mechanism also applies during cancer cell metastasis , we analyzed the bioenergetic status of breast cancer lymph node metastases , by employing a series of metabolic protein markers . For this purpose , we used MCT4 to identify glycolytic cells . Similarly , we used TO MM20 and COX staining as markers of mitochondrial mass and OXPHOS activity , respectively . Consistent with the \" reverse Warburg effect, \" our results indicate that metastatic breast cancer cells amplify oxidative mitochondrial metabolism ( OXPHOS ) and that adjacent stromal cells are glycolytic and lack detectable mitochondria . Glycolytic stromal cells included cancer-associated fibroblasts , adipocytes and inflammatory cells . Double labeling experiments with glycolytic ( MCT4 ) and oxidative ( TO MM20 or COX ) markers directly shows that at least two different metabolic compartments co-exist , side-by-side , within primary tumors and their metastases .

We have recently shown that penta-1,2,3,4,6-O-galloyl-β-D-glucose ( PGG ) induced S-phase arrest in prostate cancer ( PCa ) cells through inhibiting DNA replicative synthesis and G(1) arrest , in addition to inducing cell death at higher levels of exposure . We and others have shown that PGG through intraperitoneal ( i.p. ) injection exerts a strong in vivo growth suppression of human PCa xenograft models in athymic nude mice . This study aims to test the hypothesis that the novel targeting actions of PGG are applicable to BCa cells , especially those lacking proven druggable targets . METHODS Mono-layer cell culture models of p53-wild type estrogen receptor ( ER)-dependent MCF-7 BCa cells and p53-mutant ER-/progesterone receptor ( PR)- and Her2-regular ( triple-negative ) MDA-MB-231 BCa were exposed to PGG for a comprehensive investigation of cellular consequences and molecular targets/mediators . To test the in vivo efficacy , female athymic mice inoculated with MDA-MB-231 xenograft were treated with 20mg PGG/kg body weight by daily gavage starting 4 days after cancer cell inoculation . RESULTS Exposure to PGG induced S-phase arrest in both cell lines as indicated by the lack of 5-bromo2'-deoxy-uridine ( BrdU ) incorporation into S-phase cells as well as G(1) arrest . Higher levels of PGG induced more caspase-mediated apoptosis in MCF-7 , in strong association with induction of P53 Ser(15) phosphorylation , than in MDA-MB-231 cells . The cell cycle arrests were achieved without an induction of cyclin dependent kinase ( CDK ) inhibitory proteins P21(Cip1) and P27(Kip1) . PGG treatment led to decreased cyclin D1 in both cell lines and over-expressing cyclin D1 attenuated G(1) arrest and hastened S arrest . In serum-starvation synchronized MCF-7 cells , down-regulation of cyclin D1 was associated with de-phosphorylation of retinoblastoma ( Rb ) protein by PGG shortly before G(1)-S transition . In vivo , oral administration of PGG led to a greater than 60% inhibition of MDA-MB231 xenograft growth without adverse effect on host body weight . CONCLUSIONS Our in vitro and in vivo data support PGG as a potential drug candidate for breast cancer with novel targeting actions , especially for a triple negative BCa xenograft model .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;resisting cell death" } ]

Here we show that 4E-BP1 , one major repressor of cap-dependent translation , plays a critical role in density-mediated cell cycle arrest. 4E-BP1 promoter is activated and 4E-BP1 protein amount increases as cells reach confluence . Conversely , a much less marked density-dependent inhibition of cell proliferation is observed upon 4E-BP1 silencing . We further show that at high density , progression through the G₁ phase of the cell cycle is faster and Cyclin D1 protein is induced in different cell types where 4E-BP1 has been either downregulated ( stable shRNA expression or transient siRNA transfection ) or removed ( knock-out ) . Thus 4E-BP1 appears as an important mediator of contact inhibition .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors" } ]

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 .

Several lines of biochemical evidence support these observations . A possible role of circulating steroid hormones in the etiology of lung cancer has been hypothesized . In the present paper , we have studied the expression of the estrogen receptors ( ER)-alpha and ER beta in histologically normal human lung tissue and lung tumor cell lines . Relative ER mRNA levels were measured by reverse transcriptase-PCR and normalized to the level of expression of the glyceraldehyde 3-phosphate dehydrogenase gene ( GAPDH ) . In lung tissue , an ER alpha transcript was found at various levels in 38 out of 46 cases ( 83% ) . ER beta was expressed in all cases . The ERs were expressed at similar levels in females and males , and the levels of ER alpha and ER beta mRNA were significantly related ( P<0.0001 ) . Compared with the lung tissue , ER expression levels were lower in 16 human lung tumor cell lines and two immortalized human bronchial epithelial cell lines . Five of the tumor cell lines ( 31% ) expressed detectable levels of ER alpha and both of the immortalized cell lines showed a weak ER alpha expression level . All cell lines expressed the ER beta . The lung cell lines BEAS-2B and DB354 showed significantly reduced cell proliferation in response to tamoxifen and a minor increased growth in response to 17 beta-estradiol . In conclusion , ER genes are abundantly expressed in both histologically normal human lung and lung tumor cell lines . This indicates a possible role of ERs in lung carcinogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

For this purpose , molecules that inhibit matrix metalloproteinases activity or induce the expression of their natural inhibitor , the tissue inhibitor of metalloproteinases ( TIMPs ) , are potentially interesting . In a previous study , we have shown that synthetic ligands binding to cell surface nucleolin/nucleophosmin and known as HB 19 for the lead compound and NucAnt 6L ( N6L ) for the most potent analog , inhibit both tumor growth and angiogenesis . Furthermore , they prevent metastasis in a RET transgenic mice model which develops melanoma . Here , we investigated the effect of N6L on the invasion capacity of MDA-MB-435 melanoma cells . Our results show that the multivalent pseudopeptide N6L inhibited Matrigel invasion of MDA-MB-435 cells in a modified Boyden chamber model . This was associated with an increase in TIMP-3 in the cell culture medium without a change in TIMP-3 mRNA expression suggesting its release from cell surface and/or extracellular matrix . This may be explained by our demonstrated N6L interaction with sulfated glycosaminoglycans and consequently the controlled bioavailability of glycosaminoglycan-bound TIMP-3 . The implication of TIMP-3 in N6L-induced inhibition of cell invasion was evidenced by siRNA silencing experiments showing that the loss of TIMP-3 expression abrogated the effect of N6L . The inhibition of tumor cell invasion by N6L demonstrated in this study , in addition to its previously established inhibitory effect on tumor growth and angiogenesis , suggests that N6L represents a promising anticancer drug candidate warranting further investigation .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;inducing angiogenesis" } ]

MSCs are also employed as drug carriers for tumor therapy due to their ability to migrate to tumor tissue . However , due to the immunosuppressive function of MSCs , the application of MSCs in prostate cancer therapy remains limited . In this study , we investigated the underlying mechanism by which MSCs enable prostate cancer cells to escape from immune surveillance in the inflammatory microenvironment . Firstly , we demonstrated that compared with the control groups , MSCs pretreated with IL-1α effectively promoted the growth of the mouse prostate cancer cell line RM-1 invivo . Furthermore , when RM-1 prostate cancer cells were co-injected with MSCs pretreated with IL-1α , tumor incidence significantly increased in allogeneic recipients . In addition , we investigated the mechanism through which MSCs promote the ability of RM-1 cells to escape from immune injury . The results revealed that IL-1α led to the upregulation of TGF-β in MSCs . The inflammatory cytokine-induced promotive effect of MSCs on RM-1 cells in vivo was inhibited by TGF-β siRNA . The results of our study suggest that inflammatory cytokines induce the immunosuppressive function of MSCs which enables prostate cancer cells to escape from immune injury .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;tumor promoting inflammation;avoiding immune destruction" } ]

Chronic inflammation is a recognized risk factor for carcinogenesis . Cyclooxygenase-2 ( COX-2 ) is a mediator of inflammatory pathway and may , therefore , contribute to carcinogenesis . There are several reports that suggest the association between CS and COX-2 associated risk to cancer . In the present study , we examined the role of celecoxib ( a selective COX-2 inhibitor ) in modulating the oxidative stress caused by CS inhalation in mice . CS exposure for a period of 10 weeks caused oxidative stress in the pulmonary and hepatic tissues , as evident from the increase in lipid peroxidation levels ( LPO ) and decrease in reduced glutathione ( GSH ) levels . Celecoxib ( 125 mg/kg body weight for 8 weeks ) administration to CS inhaling mice reduced the oxidative stress by decreasing the LPO levels and enhancing the GSH levels in comparison to the CS-exposed group . CS exposure repressed the enzymatic antioxidant defense system , as evident from the decrease in catalase ( CAT ) and superoxide dismutase ( SOD ) activities . Co-adminstration of celecoxib considerably reversed the changes in the enzymatic antioxidant defense system . Histopathological studies of lungs showed that CS exposure induced alveolar wall destruction and air space enlargement . In co-treated group , the alveolar septa were thicker than normal with apparent infiltration of inflammatory cells . In CS-exposed group , hepatic tissue exhibited vacuolization and macrophage infiltration . Co-treatment with celecoxib restored the normal histoarchitechture in hepatic tissues of CS inhaling mice . Thus , the present study demonstrated that celecoxib adminstration reduced the oxidative stress-mediated risk to carcinogenesis , due to its ability to boost the antioxidant defense system .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

This study aimed to examine whether dendritic cell ( DC ) immunization could reverse TGF-beta-induced immunosuppression by simulating the in vivo interaction among infused DCs , host T cells , and tumor-secreted TGF-beta in an in vitro study . We found that both immature and mature DCs were relatively resistant to TGF-beta . The addition of TGF-beta to naive human CD4+ T cells , which are required by genetically modified DC to elicit antitumor immunity , resulted in their hyporesponsiveness to DC stimulation in a dose-dependent manner . When activated by allogeneic DCs in the presence of TGF-beta , CD4+ T cells displayed a reduced capacity to proliferate . More importantly , activated CD4+ T cells induced by DC stimulation were very sensitive to TGF-beta , and this susceptibility was enhanced by their previous exposure to TGF-beta . The underlying mechanism was linked to TGF-beta-induced apoptosis of activated T cells . However , the presence of stimulation from DC or antibodies to CD3 plus CD28 could partly reverse the immunosuppressive effect of TGF-beta on activated CD4+ T cells . Taken together , our results indicate that the efficacy of DC immunization may be impaired by tumor-derived TGF-beta .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;avoiding immune destruction;resisting cell death" } ]

However , the genetic alterations that transform NSCs into glioma-initiating cells remain elusive . Using a unique transposon mutagenesis strategy that mutagenizes NSCs in culture , followed by additional rounds of mutagenesis to generate tumors in vivo , we have identified genes and signaling pathways that can transform NSCs into glioma-initiating cells . Mobilization of Sleeping Beauty transposons in NSCs induced the immortalization of astroglial-like cells , which were then able to generate tumors with characteristics of the mesenchymal subtype of GBM on transplantation , consistent with a potential astroglial origin for mesenchymal GBM . Sequence analysis of transposon insertion sites from tumors and immortalized cells identified more than 200 frequently mutated genes , including human GBM-associated genes , such as Met and Nf1 , and made it possible to discriminate between genes that function during astroglial immortalization vs. later stages of tumor development . We also functionally validated five GBM candidate genes using a previously undescribed high-throughput method . Finally , we show that even clonally related tumors derived from the same immortalized line have acquired distinct combinations of genetic alterations during tumor development , suggesting that tumor formation in this model system involves competition among genetically variant cells , which is similar to the Darwinian evolutionary processes now thought to generate many human cancers . This mutagenesis strategy is faster and simpler than conventional transposon screens and can potentially be applied to any tissue stem/progenitor cells that can be grown and differentiated in vitro .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;genomic instability and mutation" } ]

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 .

We previously reported that ataxia-telangiectasia mutated deficiency resets the primary radiation lethal pathway , allowing CS-mediated apoptosis at the low-dose range of radiation . The mechanism for this event , termed target reordering , remains unknown . Here , we show that inactivation of DNA damage repair pathways signals CS-mediated apoptosis in crypt SCCs , presumably via persistent unrepaired DNA double-strand breaks ( DSBs ) . Genetic loss of function of sensors and transducers of DNA DSB repair confers the CS-mediated lethal pathway in intestines of sv129/B6Mre11(ATLD1/ATLD1) and C57BL/6(Prkdc/SCID) ( severe combined immunodeficient ) mice exposed to low-dose radiation . In contrast , CS-mediated SCC lethality was mitigated in irradiated gain-of-function Rad50(s/s) mice , and epistasis studies order Rad50 upstream of Mre11 . These studies suggest unrepaired DNA DSBs as causative in target reordering in intestinal SCCs . As such , we provide an in vivo model of DNA damage repair that is standardized , can be exploited to understand allele-specific regulation in intact tissue , and is pharmacologically tractable .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;genomic instability and mutation;evading growth suppressors" } ]

VA-13 is a line of immortalized cells established by transformation of WI-38 cells by SV40 virus . To determine whether SV40 large T ( SV40-T ) antigen is essential for this immortalization of WI-38 cells we introduced an antisense gene for T antigen into VA-13 . Two morphologically different types of antisense transformant ( VA-AS5-8 and VA-AS37-8 ) were obtained . In both antisense transformants the expression of T antigen was reduced by more than 70% as compared to that in the parent cells . The morphology of the antisense transformants indicated a partial conversion to the senescent phenotype of WI-38 . The relative number of cells in the S phase of the antisense transformants was decreased as compared to that in cultures of VA-13 and about 50% of cells were at G1/0 . The doubling time of the transformants was prolonged to close to the doubling time of WI-38 . The level of expression of retinoblastoma protein ( pRB ) complexed with SV40-T antigen of the antisense transformants was significantly decreased although the level of total pRB was much higher than that in VA-13 . The pRB was present exclusively in the underphosphorylated form . Thus , the decreased level of formation of the complex between SV40-T and pRB or the underphosphorylation of pRB may explain the suppression of growth of antisense transformants . Together , these results show that an antisense gene for SV40-T antigen can efficiently block the cell proliferation and the cell immortalization of VA-13 cells .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;sustaining proliferative signaling" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;inducing angiogenesis" } ]

Although oriental and Ayurvedic medicines have traditionally used CUR in the treatment of diseases , conventional medicine has just begun to recognize its potential therapeutic value . Numerous recent studies have demonstrated the ability of CUR to halt or prevent certain types of cancer , decrease inflammation , and improve cardiovascular health . However , very few studies have examined its ability to protect against drug-induced organ injury . This study explored whether CUR pre-exposure has the potential to prevent acetaminophen ( APAP)-induced : ( i ) hepatotoxicity , ( ii ) genomic injury , ( iii ) oxidative stress in the liver , and ( iv ) apoptotic and necrotic cell deaths in the liver in vivo . Additional goals were to investigate the interplay of pro- and anti-apoptotic genes and their ultimate impact on various forms of cell death . In order to study the CUR-APAP interaction , male B6C3F1 mice were gavaged with CUR ( 17 mg/kg/day , p.o. ) for 12 days followed by a single APAP exposure ( 400 mg/kg , ip ) . Four groups of animals ( control , CUR , APAP , CUR+APAP ) were sacrificed 24 h after APAP exposure . The results indicated that APAP-induced liver injury associated events as serum ALT ( 80-fold ) , lipid peroxidation ( 357% ) and DNA fragmentation ( 469% ) were markedly reduced to 3-fold , 134% and 162% , respectively , in the CUR+APAP group . The APAP-induced increase in expression of pro-apoptotic genes ( Bax , caspase-3 ) decreased while expression of anti-apoptotic genes ( Bcl-XL ) increased in CUR preexposed mouse livers , and these changes were mirrored in the pattern of apoptotic and necrotic cell deaths . Levels of DNA damage sensor P⁵³ and its counterpart Mdm2 were also analyzed during this interaction . Based on the available literature , and these results , it seems likely that CUR may impart global protection in vivo against drug-induced liver injury by opposing several crucial events instrumental to both apoptosis and necrosis .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;tumor promoting inflammation" } ]

We report our experience with the diagnosis , evaluation and treatment of this novel form of hereditary kidney cancer . MATERIALS AND METHODS Patients with suspected hereditary kidney cancer were enrolled on a National Cancer Institute institutional review board approved protocol to study inherited forms of kidney cancer . Individuals from families with germline SDHB , SDHC and SDHD mutations , and kidney cancer underwent comprehensive clinical and genetic evaluation . RESULTS A total of 14 patients from 12 SDHB mutation families were evaluated . Patients presented with renal cell cancer at an early age ( 33 years , range 15 to 62 ) , metastatic kidney cancer developed in 4 and some families had no manifestation other than kidney tumors . An additional family with 6 individuals found to have clear cell renal cell cancer that presented at a young average age ( 47 years , range 40 to 53 ) was identified with a germline SDHC mutation ( R133X ) Metastatic disease developed in 2 of these family members . A patient with a history of carotid body paragangliomas and an aggressive form of kidney cancer was evaluated from a family with a germline SDHD mutation . CONCLUSIONS SDH mutation associated renal cell carcinoma can be an aggressive type of kidney cancer , especially in younger individuals . Although detection and management of early tumors is most often associated with a good outcome , based on our initial experience with these patients and our long-term experience with hereditary leiomyomatosis and renal cell carcinoma , we recommend careful surveillance of patients at risk for SDH mutation associated renal cell carcinoma and wide surgical excision of renal tumors .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;genomic instability and mutation" } ]

The effective activation and resolution of innate immune responses relies on the production and posttranscriptional regulation of mRNAs encoding inflammatory effector proteins . The RNA-binding protein HuR binds to and regulates such mRNAs , but its exact role in inflammation remains unclear . Here we show that HuR maintains inflammatory homeostasis by controlling macrophage plasticity and migration . Mice lacking HuR in myeloid-lineage cells , which include many of the cells of the innate immune system , displayed enhanced sensitivity to endotoxemia , rapid progression of chemical-induced colitis , and severe susceptibility to colitis-associated cancer . The myeloid cell-specific HuR-deficient mice had an exacerbated inflammatory cytokine profile and showed enhanced CCR2-mediated macrophage chemotaxis . At the molecular level , activated macrophages from these mice showed enhancements in the use of inflammatory mRNAs ( including Tnf , Tgfb , Il10 , Ccr2 , and Ccl2 ) due to a lack of inhibitory effects on their inducible translation and/or stability . Conversely , myeloid overexpression of HuR induced posttranscriptional silencing , reduced inflammatory profiles , and protected mice from colitis and cancer . Our results highlight the role of HuR as a homeostatic coordinator of mRNAs that encode molecules that guide innate inflammatory effects and demonstrate the potential of harnessing the effects of HuR for clinical benefit against pathologic inflammation and cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

To investigate the role of microRNAs ( miRNAs ) in CKII downregulation during senescence , we employed computational algorithms . Four miRNAs ( miR-186 , miR-216b , miR-337-3p , and miR-760 ) were predicted to be miRNAs against CKIIα mRNA . Mimics of all four miRNAs jointly downregulated CKIIα expression in HCT116 cells . Reporter analysis and RT-PCR have suggested that these four miRNAs may stimulate degradation of CKIIα mRNA by targeting its 3 ' untranslated regions ( UTRs ) . The four miRNA mimics increased senescent-associated β-galactosidase ( SA-β-gal ) staining , p53 and p21(Cip1/WAF1) expression , and reactive oxygen species ( ROS ) production . In contrast , concomitant knockdown of the four miRNAs by antisense inhibitors increased the CKIIα protein level and suppressed CKII inhibition-mediated senescence . Finally , CKIIα overexpression antagonized senescence induced by the four miRNA mimics . Therefore , the present results show that miR-186 , miR-216b , miR-337-3p , and miR-760 cooperatively promote cellular senescence through the p53-p21(Cip1/WAF1) pathway by CKII downregulation-mediated ROS production in HCT116 cells .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;tumor promoting inflammation" } ]

Highly invasive malignant cells exhibit diminished CIL when they contact stromal cells , which allows invasion of the tissue by tumors . We show that Nm23-H1 is essential for the suppression of Rac1 through inactivation of Tiam1 at the sites of cell-cell contact , which plays a pivotal role in CIL . U87MG cells show CIL when they contact normal glia . In spheroid confrontation assays U87MG cells showed only limited invasion of the glial population , but reduction of Nm23-H1 expression in U87MG cells abrogated CIL resulting in invasion . In U87MG cells , Nm23-H1 is translocated to the sites of contact with glia through association with α-catenin and N-cadherin . Mutants of Nm23-H1 , which lacked the binding ability with Tiam1 , or α-catenin did not restore CIL . Moreover , the expression of ephrin-B1 in tumor cells disrupted CIL and promoted invasion . As one mechanism , ephrin-B1 inhibits the association of Nm23-H1 with Tiam1 , which contributes for activation of Rac1 . These results indicate a novel function of Nm23-H1 to control CIL , and its negative regulation by ephrin-B1 .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;activating invasion and metastasis" } ]

MATERIALS AND METHODS A retrospective , analytical study was conducted of surgical specimens from 139 patients with localized renal cell carcinoma who underwent nephrectomy from 1993 to 2005 . Tumor necrosis , microscopic vascular invasion , and sinus fat invasion were analyzed and compared to the classical factors : TNM classification , Fuhrman grade , and tumor size . For statistical analysis , variables analyzed were categorized as pT1 , 2 vs pT3 , 4 ; Fuhrman grade 1 , 2 vs 3 , 4 ; tumor size &lt ; 7 cm vs >or= 7cm ; tumor necrosis vs no tumor necrosis ; microvascular invasion of sinus fat vs no invasion . Cancer-specific survival probability and disease-free survival were calculated . A descriptive and analytical statistical analysis was performed using logistic regression for univariate and multivariate analyses . Dependent variables were used to analyze cancer-specific survival rates . Disease-free survival was estimated using a Cox regression model and Kaplan-Meier curves . RESULTS In the univariate analysis , all variables analyzed had a significant influence on death for renal cell carcinoma . In the multivariate analysis , the variable having the greatest influence was Fuhrman grade ( p = 0,032 ) . The variables significantly influencing disease-free survival , estimated by the Cox method , were the pT stage ( p = 0.038 ) and Fuhrman grade ( p = 0.048 ) . CONCLUSIONS In patients with clinically localized renal cell carcinoma undergoing nephrectomy , pT stage and Fuhrman grade are the most important prognostic factors for survival and disease-free survival . Tumor necrosis , microscopic vascular invasion , and sinus fat invasion are prognostic factors for death from renal carcinoma which are associated to TNM classification , Fuhrman grade , and tumor size .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;resisting cell death" } ]

Osteolytic bone lesions are detected in 80% of patients because of increased osteoclastic bone resorption and reduced osteoblastic bone formation . MMCs are found closely associated with sites of increased bone resorption . Osteoclasts strongly support MMC survival in vitro . To further elucidate the mechanisms involved in osteoclast/MMC interaction , we have identified 552 genes overexpressed in osteoclasts compared with other bone marrow cell subpopulations . Osteoclasts express specifically genes coding for 4 CCR2-targeting chemokines and genes coding for MMC growth factors . An anti-CCR2 monoclonal antibody blocked osteoclast chemoattractant activity for MMC , and CCR2 chemokines are also MMC growth factors , promoting mitogen-activated protein kinase activation in MMC . An anti-insulin growth factor-1 receptor monoclonal antibody completely blocked the osteoclast-induced survival of MMC suppressing both osteoclast and MMC survival . Specific a proliferation-inducing ligand or IL-6 inhibitors partially blocked osteoclast-induced MMC survival . These data may explain why newly diagnosed patients whose MMC express high levels of CCR2 present numerous bone lesions . This study displays additional mechanisms involved in osteoclast/MMC interaction and suggests using CCR2 and/or insulin growth factor-1 targeting strategies to block this interaction and prevent drug resistance .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Together with anaerobic glycolysis , the Warburg effect , formally corresponding to uncoupling glycolysis from oxidative phosphorylation , directly participates in cancer aggressiveness , supporting both tumor progression and dissemination . The transcription factor hypoxia-inducible factor-1 ( HIF-1 ) is a key contributor to glycolysis . It stimulates the expression of glycolytic transporters and enzymes supporting high rate of glycolysis . In this study , we addressed the reverse possibility of a metabolic control of HIF-1 in tumor cells . We report that lactate , the end-product of glycolysis , inhibits prolylhydroxylase 2 activity and activates HIF-1 in normoxic oxidative tumor cells but not in Warburg-phenotype tumor cells which also expressed lower basal levels of HIF-1α . These data were confirmed using genotypically matched oxidative and mitochondria-depleted glycolytic tumor cells as well as several different wild-type human tumor cell lines of either metabolic phenotype . Lactate activates HIF-1 and triggers tumor angiogenesis and tumor growth in vivo , an activity that we found to be under the specific upstream control of the lactate transporter monocarboxylate transporter 1 ( MCT1 ) expressed in tumor cells . Because MCT1 also gates lactate-fueled tumor cell respiration and mediates pro-angiogenic lactate signaling in endothelial cells , MCT1 inhibition is confirmed as an attractive anticancer strategy in which a single drug may target multiple tumor-promoting pathways .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;inducing angiogenesis" } ]

From antiquity Verbascum thapsus has been used as a medicinal herb , it contains diverse polysaccharides , iroid glycosides , flavonoids , saponins , volatile oils and phenylentanoids . Inducible nitric oxide synthase ( iNOS ) represents one of the three isoforms that produce nitric oxide using L-arginine as a substrate in response to an increase in superoxide anion activated by NF-kB . It is implicated in different pathophysiological events and its expression increases greatly during an inflammatory process , due to oxidative stress and the activation of the enzymes of the antioxidant network such as SOD , CAT and GPx.In this study an inflammatory state was reproduced by treating THP-1 cells ( human myelomonocytic leukaemia ) with pro-inflammatory stimuli , such as LPS and IFN-gamma , obtaining an up-regulation both in the expression and in the activity of iNOS . The aim of the work was to investigate the antiinflammatory action of verbascoside using a concentration of 100 mum . The results show a significant decrease of the expression and activity of iNOS , extracellular O(2) ( - ) production , SOD , CAT and GPx activity when the cells were treated with verbascoside . Based on these results it is hypothesized that verbascoside has antiinflammatory properties since it reduces the production of superoxide radicals and consequently reduces the activity of iNOS .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

METHODS A recombinant plasmid containing a constitutively driven NIS gene ( pcDNA3-NIS ) was transfected into the human colon cancer cell line HCT116 , and stable cell lines were established . The stable cells were subcutaneously injected into the nude mice . When the diameter reached 10 mm , the xenografts were excised , cut into small fragments , and orthotopically implanted into the cecal walls of another nude mice. 99mTcO4- SPECT/CT imaging was initiated 8 weeks later and repeated every 1 to 2 weeks . RESULTS The production and function of NIS protein was confirmed in vitro by Western blotting and 99mTcO4- uptake assay . On SPECT/CT imaging , focal 99mTcO4- uptake was detected in the liver . Necropsy revealed local growth of the orthotopic colon xenografts with extensive invasion , microscopic serosal metastasis , and metastatic foci in the corresponding hepatic regions showing focal 99mTcO4- uptake . Immunohistochemistry revealed high levels of NIS expression in cells forming liver tumor , indicating that the liver tumor cells originated from the orthotopic colon xenografts . CONCLUSIONS The present proof-of-concept study provided a rationale for employing a radionuclide reporter gene for the specific visualization of spontaneous liver metastasis in living mice .

Although Nur77 affects cell proliferation and apoptosis through its capability of binding to a variety of response elements and regulating their transactivation activities , the intrinsic function of Nur77 is not yet fully understood ; in particular , its regulation of apoptosis and proliferation has been characterized as cell type-dependent and agent context-dependent . In this study , Nur77 can be seen to regulate apoptosis via its expression and translocation , rather than its transactivation activity in gastric cancer cells . Nur77 was constitutively expressed in BGC-823 cells . The tetradecanoylphorbol-1,3-acetate ( TPA ) treatment not only resulted in up-regulation of the Nur77 mRNA level , but also led to translocation of Nur77 protein from the nucleus to the mitochondria , and caused the release of cytochrome c . This TPA-induced translocation of Nur77 was in association with the initiation of apoptosis in gastric cancer cells . Although all-trans retinoic acid ( ATRA ) could not induce apoptosis in BGC-823 cells due to failure of stimulating Nur77 translocation , expression of Nur77 in the nucleus was required for cell growth inhibition by ATRA . Transfection of antisense Nur77 receptor into BGC-823 cells resulted in resistance of cell growth against ATRA inhibition , and the cells were still arrested in the S phase .

Diminished NKX3.1 expression is associated with prostate epithelial cell proliferation in vitro and with increasing Gleason grade in patient samples . Mouse Nkx3.1 also functions as a negative regulator of prostate cell growth in prostate cancer models . Identifying biological and environmental factors that modulate NKX3.1 accumulation is therefore central to efforts aimed at elucidating prostate growth control mechanisms . To determine the effect of inflammation on Nxk3.1 accumulation , bacterial prostatitis was induced by intraurethral inoculation of a uropathogenic E. coli strain in mice . Nkx3.1 expression was profoundly reduced in infected prostate lobes and correlated with increased expression of a proliferation marker . Androgen receptor levels were also reduced in concert with Nkx3.1 , and a marked increase in the basal cell marker p63 was observed . Analyses of the inflammatory infiltrate revealed a classic acute inflammatory response that attained characteristics of a chronic state within fourteen days postinoculation . Comparison of the four prostate lobes revealed clear differences in the extent of inflammation . These data demonstrate that acute inflammation in response to a bacterial agent in the prostate is associated with a significant diminution in the level of a key regulator of prostate cell proliferation . These observations provide a plausible mechanism whereby prostate inflammation may establish a local environment conducive to epithelial cell growth .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;tumor promoting inflammation" } ]

In the present study , we used surface-shielded Tf-PEI/DNA complexes for delivering the gene for a highly potent cytokine , tumor necrosis factor-alpha ( TNFalpha ) . TNFalpha is known for its ability to induce hemorrhagic tumor necrosis and tumor regression . However , the therapeutic application of TNFalpha is hampered by its high systemic toxicity dictating the need to target TNFalpha activity to the tumor . Systemic application of surface-shielded Tf-PEI complexes with the TNFalpha gene resulted in preferential expression of TNFalpha in the tumor without detectable TNFalpha serum levels , in contrast to the application of nontargeted complexes . Tumor-targeted TNFalpha gene delivery induced pronounced hemorrhagic tumor necrosis and inhibition of tumor growth in three murine tumor models of different tissue origins , Neuro2a neuroblastoma , MethA fibrosarcoma , and M-3 melanoma , with complete tumor regressions observed in the MethA model . No systemic TNF-related toxicity was observed due to the localization of the TNFalpha activity to the tumor .

METHODS The cells were incubated for 24h with 70μM c9,t11-CLA and then X-irradiated . The following methods were used : gas chromatography ( incorporation of the CLA isomer ) , flow cytometry ( cell cycle ) , cloning ( survival ) , Western blotting ( protein distribution in membrane fractions ) , and pulse-field gel electrophoresis ( rejoining of DNA double-strand breaks ) . In parallel , DNA-PK activity , γ-H2AX foci numbers and chromatid fragmentation were estimated . Gene expression was analysed by RT-PCR and chromosomal aberrations by the mFISH method . Nuclear accumulation of the EGF receptor ( EGFR ) was monitored by ELISA . RESULTS AND CONCLUSIONS C9,t11-CLA sensitized HT-29 cells to X-radiation . This effect was not due to changes in cell cycle progression or DNA-repair-related gene expression . Post-irradiation DSB rejoining was delayed , corresponding with the insufficient DNA-PK activation , although chromosomal aberration frequencies did not increase . Distributions of cholesterol and caveolin-1 in cellular membrane fractions changed . The nuclear EGFR translocation , necessary to increase the DNA-PK activity in response to oxidative stress , was blocked . We suppose that c9,t11-CLA modified the membrane structure , thus disturbing the intracellular EGFR transport and the EGFR-dependent pro-survival signalling , both functionally associated with lipid raft properties . GENERAL SIGNIFICANCE The results point to the importance of the cell membrane interactions with the nucleus after injury inflicted by X -rays . Compounds like c9,t11-CLA , that specifically alter membrane properties , could be used to develop new anticancer strategies .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;sustaining proliferative signaling;tumor promoting inflammation" } ]

Even in the absence of estrogen , ERα can be activated by growth factors , including the epidermal growth factor ( EGF ) . EGF induces a transcriptional program distinct from estrogen ; however , the mechanism of the stimulus-specific response is unknown . Here we show that the EGF-induced ERα genomic targets , its cistromes , are distinct from those induced by estrogen in a process dependent on the transcription factor AP-1 . The EGF-induced ERα cistrome specifically regulates genes found overexpressed in ERBB2-positive human breast cancers . This provides a potential molecular explanation for the endocrine therapy resistance seen in ERα-positive breast cancers that overexpress ERBB2 . These results suggest a central role for ERα in hormone-refractory breast tumors dependent on growth factor pathway activation and favors the development of therapeutic strategies completely antagonizing ERα , as opposed to blocking its estrogen responsiveness alone .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Because of the close association with DNA double strand break ( DSB ) repair , phosphorylation of the histone H2AX protein ( γH2AX ) , quantified by immunodetection , has recently been used as a method to study DSB induction and repair at low and clinically relevant radiation doses . However , the lack of consistency in literature points to the need to further validate the role of H2AX phosphorylation in DSB repair and the use of this technique to determine intrinsic radiosensitivity . In the present study we used human mammary epithelial MCF10A cells , characterized by a radiosensitive phenotype due to reduced levels of the Ku70 and Ku80 repair proteins , and investigated whether this repair-deficient cell line displays differences in the phosphorylation pattern of H2AX protein compared to repair-proficient MCF10A cells . This was established by measuring formation and disappearance of γH2AX foci after irradiating synchronized cell populations with ( 60)Co γ-rays . Our results show statistically significant differences in the number of γH2AX foci between the repair-deficient and -proficient cell line , with a higher amount of γH2AX foci present at early times post-irradiation in the Ku-deficient cell line . However , the disappearance of those differences at later post-irradiation times questions the use of this assay to determine intrinsic radiosensitivity , especially in a clinical setting .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Though Mre11p has both single-stranded and double-stranded 3'-5 ' exonuclease activity in vitro , null mutants of MRE11 , RAD50 , and XRS2 exhibit reduced 5'-3 ' resection of HO-induced double-strand breaks ( DSBs ) in vivo . In this study , we analyzed four mre11 mutants harboring changes in the N-terminus of Mre11p where the four phosphoesterase motifs specify the in vitro nuclease activities of Mre11p and its homologues . We find that the 5'-3 ' resection defects in vivo do not correlate with several mitotic phenotypes : non-homologous end-joining ( NHEJ ) , telomere length maintenance , and adaptation to the DNA damage-inducible G2/M checkpoint . Overexpression of the 5'-3 ' exonuclease Exo1p in a mre11Delta strain partially increased 5'-3 ' resection and partially suppressed both methyl methanesulfonate ( MMS ) hypersensitivity and adaptation phenotypes , but did not affect telomere length or NHEJ . Surprisingly , the co-expression of two alleles , mre11-58S and mre11-N113S , each of which confers MMS hypersensitivity and short telomeres , can fully complement the MMS sensitivity and shortened telomere length of mre11Delta cells .

Although anti-carcinogenic , anti-oxidant , anti-inflammation , and anti-angiogenic properties have been reported , the effect of curcumin on breast cancer metastasis is unknown . Matrix metalloproteinase-9 ( MMP-9 ) is a major component in cancer cell invasion . In this study , we investigated the inhibitory effect of curcumin on 12-O-tetradecanoylphorbol-13-acetate ( TPA)-induced MMP-9 expression and cell invasion and the molecular mechanisms involved in MCF-7 cells . Our results showed that curcumin inhibits TPA-induced MMP-9 expression and cell invasion through suppressing NF-κB and AP-1 activation . Also , curcumin strongly repressed the TPA-induced phosphorylation of p38 and JNK and inhibited TPA-induced translocation of PKCα from the cytosol to the membrane , but did not affect the translocation of PKCδ .

Nearly 20 years after the Seveso , Italy , accident , we measured immunoglobulin and complement plasma levels in a random sample of the population in the most highly exposed zones ( n = 62 ) and in the surrounding noncontaminated area ( n = 58 ) .

The outgrowth of these keratinocyte-derived skin lesions is enhanced by the ability of UVB to impair an immune response that would otherwise eliminate them . Studies in a range of inbred mouse strains as well as mast cell-depleted mice reconstituted with mast cell precursors support a functional link between histamine-staining dermal mast cells and the extent of susceptibility to UVB-induced systemic immunomodulation . Humans , like mouse strains , display variations in dermal mast cell prevalence . In a study of Danish and South Australian BCC patients and control subjects , one 4-mm punch biopsy of non-sun-exposed buttock skin was sampled from each participant . This skin site was investigated to avoid any changes in mast cell prevalence caused by sun exposure . Two sections ( 4 microm ) per biopsy were immunohistochemically stained for detection of histamine-containing dermal mast cells . Computer-generated image analysis evaluated dermal mast cell prevalence in both sections by quantifying the total number of mast cells according to the total dermal area ( expressed as mast cells per square millimeter ) . This technique enabled us to detect heterogeneity of dermal mast cell prevalence in buttock skin between individuals and provided evidence of an association between high dermal mast cell prevalence and BCC development in two diverse populations . We hypothesize that mast cells function in humans , as in mouse strains , by initiating immunosuppression following UV irradiation and , thereby , allowing a permissive environment for the development of BCC . Thus , a high dermal mast cell prevalence as demonstrable in buttock skin is a significant predisposing factor for development of BCC in humans .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

It has been reported that emergence from this growth arrest by the abrogation of p16(INK4a) , a cyclin-dependent kinase inhibitor , and expression of the catalytic component of human telomerase ( hTERT ) are necessary for HMEC immortalization . Here we show that primary HMECs , grown on feeder layers , do not undergo this growth arrest and can be immortalized without abrogating p16 . These findings support the concept that the so-called M0 stage represents a cell culture stress-induced growth arrest and that hTERT is sufficient to immortalize HMECs when cultured under adequate conditions .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

Monitoring tumor progression in these patients is thwarted because therapy results in tumor invisibility in contrast-enhanced ( CE ) MRI . To address this problem , we examined whether tumor progression could be monitored by metabolic mapping using ( 1)H MR spectroscopic imaging ( MRSI ) . METHODS We treated groups of BALB/c nu/nu mice carrying different orthotopic diffuse-infiltrative glioblastoma xenografts with bevacizumab ( anti-vascular endothelial growth factor [ VEGF ] antibody , n = 13 ) , cabozantinib ( combined VEGF receptor 2/c-Met tyrosine kinase inhibitor , n = 11 ) , or placebo ( n = 15 ) and compared CE-MRI with MRS-derived metabolic maps before , during , and after treatment . Metabolic maps and CE-MRIs were subsequently correlated to histology and immunohistochemistry . RESULTS In vivo imaging of choline/n-acetyl aspartate ratios via multivoxel MRS is better able to evaluate response to therapy than CE-MRI . Lactate imaging revealed that diffuse infiltrative areas in glioblastoma xenografts did not present with excessive glycolysis . In contrast , glycolysis was observed in hypoxic areas in angiogenesis-dependent compact regions of glioma only , especially after anti-angiogenic treatment . CONCLUSION Our data present MRSI as a powerful and feasible approach that is superior to CE-MRI and may provide handles for optimizing treatment of glioma . Furthermore , we show that glycolysis is more prominent in hypoxic areas than in areas of diffuse infiltrative growth . The Warburg hypothesis of persisting glycolysis in tumors under normoxic conditions may thus not be valid for diffuse glioma .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;inducing angiogenesis" } ]

In this study , we sought to identify and characterize a human PAT with activity toward N-terminally myristoylated and palmitoylated proteins . NIH/3t3 cells were stably transfected with vectors containing no insert , wild type human DHHC20 , or a serine-substituted DHHS20 mutant . Compared with control cells , cells overexpressing wild-type DHHC20 displayed an increase in palmitoylation activity toward a peptide that mimics the N-terminus of myristoylated and palmitoylated proteins , but had no change in activity toward a peptide that mimics the C-terminus of farnesylated and palmitoylated proteins . Cells expressing DHHS20 had no significant change in activity toward either peptide . Overexpression of DHHC20 also caused phenotypic changes consistent with cellular transformation , including colony formation in soft agar , decreased contact inhibition of growth , and increased proliferation under low-serum conditions . Quantitative polymerase chain reaction analyses of human tissues demonstrated that DHHC20 is expressed in a tissue-specific manner , and is overexpressed in several types of human tumors , including ovarian , breast and prostate . Overall , these results demonstrate that DHHC20 is a human N-terminal-myristoyl-directed PAT involved in cellular transformation , that may play a role in cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

Detailed data on the cytogenetic effects of anti-11,12-dihydroxy-13,14-epoxy-11,12,13,14-tetrahydrodibenzo[a,l]pyrene ( DBPDE ) in mammalian cells are not available in the literature . The aim of this study is to elucidate the mechanisms involved in the induction of chromosomal aberrations and sister chromatid exchanges ( SCEs ) by DBPDE in mammalian cells . In order to achieve this a parental ( AA8 ) and different DNA repair-deficient Chinese hamster ovary cell lines such as UV4 , UV5 , UV61 ( nucleotide excision repair , NER ) , EM9 ( base excision repair , BER ) , irs1SF ( homologous recombination repair , HRR ) and V3-3 ( non-homologous end joining , NHEJ ) were used . The most sensitive cell lines for DBPDE-induced chromosome aberrations were EM9 and irs1SF , while EM9 and V3-3 cell lines were the most sensitive in terms of SCEs induction . It can be suggested that the BER pathway plays an important role in the repair of lesions induced by DBPDE , affecting both chromosomal aberrations and SCEs induction . Moreover , the HRR pathway seems to play a role in cellular resistance to DBPDE mainly in terms of chromosomal aberration induction while the NHEJ pathway takes part affecting only the induction of SCEs .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Women who had used COCs for at least 2 years and were in continued use were compared to non-users of COCs ( control group ) . It was difficult to establish the average period of contraceptive use because in most instances there was no proper documentation on the exact dates as to when the subjects started using COCs . The number of subjects with each condition was noted from each of the following age groups ; <20 years , 20-29years , 30-39years , 40-49years and >50years . It was found that the percentage of the control group with benign conditions was higher than that of COC users in all age groups . Significant differences at 95 percent confidence level were noted for the 20-29 years age group ( z= -2.21 ) and 40-49 years age group ( z= -2.53).The number of subjects in the <20 years and >50 years age groups were too small for z-score computation . No significant differences were noted for mild to moderate cervical inflammation in all age groups . There was a higher percentage of COC users with severe cervical inflammation compared to the control group in all age groups . Significant differences were noted in the 30-39 years age group ( z=3.45 ) and 40-49 years age group ( z= 1.98 ) . A higher percentage of CIN I was noted among pooled COC users compared to the control group ( z= 2.00 ) although no significant differences were obtained within different age groups . In conclusion , severe cervical inflammation and CIN I are more frequent among Zimbabwean women who use COCs as compared to non-users of COCs . Frequencies of advanced CIN are low among women who undergo routine cytological screening because this enables early detection and subsequent treatment .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

It remains unclear why patients with germ-line p53 mutations ( i.e. , Li-Fraumeni syndrome ) are not at increased risk for gastric adenocarcinoma , despite the fact that they show a high rate of many other tumors . Furthermore , the precise relationship between germ-line p53 mutations and the response to chronic bacterial infections ( such as Helicobacter spp. ) has not been investigated . To assess the role of germ-line p53 deletions in modulating the progression to gastric cancer , p53(+/-) and wild-type ( WT ) C57BL/6 mice were infected with H. felis . The gastric pathology and immune response in these two groups of mice were analyzed for up to 15 months postinfection . The gastric fundus and antrum were evaluated independently using a 0-4 scale to score inflammation , parietal and chief cell loss , mucus metaplasia , and helicobacter colonization . Nonparametric statistical analysis was performed to determine the effects of p53(+/-) , infection status , and postinoculation ( p.i. ) time on inflammation , preneoplastic changes , invasive lesions , and helicobacter colonization. mRNA expression for gammaIFN , interleukin ( IL)-1 , IL-10 , and IL-4 was quantified by PCR . Sera were also evaluated for H. felis antibody by ELISA . Antral inflammation increased significantly with time in infected mice . There was a significant , protective effect on the development of preneoplastic fundic lesions and invasive carcinoma attributable to the deletion of one p53 allele ( P &lt ; 0.05 ) . Submucosal invasive foci were observed in 9 of 11 WT-infected mice ranging from 13 to 15 months p.i. ; invasion of adjacent submucosal blood vessels by glandular epithelia also was present in 5 of these mice . None of these lesions were observed in 33 p53(+/-) mice , infected or not , at any time p.i. p53(+/-) mice had significantly higher helicobacter colonization consistent with a Th2 host response . In sera from WT mice , IgG2a , considered a proinflammatory Th1 response , continued to rise throughout the 15-month study ( P &lt ; 0.004 ) . In contrast , IgG2a levels of the p53(+/-) mice were 50-60% lower than those of the WT mice at each time point ( P range , <0.012 to 0.002 ) and did not progress in magnitude between 12 and 15 months of chronic H. felis infection ( P = 0.167). mRNA levels for gammaIFN and IL-1 were significantly up-regulated in WT mice infected with H. felis ( P &lt ; 0.05 ) but were slightly elevated or were at background levels in p53(+/-) mice . IL-10 and IL-4 mRNA expression was not significantly different from control samples . Our results support the hypothesis that germ-line deletion of one p53 allele results in a down-regulated Th1 response to gastric helicobacter infection , possibly because of T-cell senescence , which may indirectly protect against the development of gastric cancer and other epithelial-derived neoplasms associated with chronic inflammation .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;activating invasion and metastasis;enabling replicative immortality" } ]

We recently showed the expression profile of A2A and A2B receptors in normal and tumor breast tissues . In the present study , we used semiquantitative RT-PCR to measure the A1 and A3 gene expression levels in normal and tumor breast tissues . METHODS Breast tumors ( n = 18 ) and non-neoplastic mammary tissues ( n = 10 ) were collected and histologically confirmed to be neoplastic or non-neoplastic , respectively . Total RNA was extracted and reverse transcribed into cDNA , and PCR was performed under optimized condition for each receptor subtype . Amplification of beta-actin mRNA served as control for RT-PCR . The PCR products were separated on 1.7% agarose gels . The intensity of the bands was quantitated with ImageJ software after normalization against beta-actin expression . RESULTS All breast tumor and normal tissue specimens expressed A1 and A3 adenosine receptor transcripts . However , we observed that the expression level of the A3 receptor in tumor tissues was 1.27-fold that of normal tissues , whereas there was no significant difference between the expression levels of A1 in normal and tumor tissues . CONCLUSIONS Interestingly , the results of the present study indicate that breast tumors exhibit a higher level of A3 transcripts ( than normal tissues ) and support the possible key role of A3 adenosine receptor in tumor development . However , further studies based on real-time quantitative RT-PCR are needed to identify the exact gene expression levels .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

BI-1-overexpressing HT1080 and B16F10 cells produced higher lung weights and tumor volumes after injection into the tail veins of mice . Transfection of BI-1 siRNA into cells before injection blocked lung metastasis. in vitro , the overexpression of BI-1 increased cell mobility and invasiveness , with highly increased glucose consumption and cytosolic accumulation of lactate and pyruvate , but decreased mitochondrial O(2) consumption and ATP production . Glucose metabolism-associated extracellular pH also decreased as cells excreted more H(+) , and sodium hydrogen exchanger ( NHE ) activity increased , probably as a homeostatic mechanism for intracellular pH . These alterations activated MMP 2/9 and cell mobility and invasiveness , which were reversed by the NHE inhibitor , 5-(N-ethyl-N-isopropyl) amiloride ( EIPA ) , suggesting a role for NHE in cancer metastasis . In both in vitro and in vivo experiments , C-terminal deleted ( CDeltaBI-1 ) cells showed similar results to control cells , suggesting that the C-terminal motif is required for BI-1-associated alterations of glucose metabolism , NHE activation and cancer metastasis . These findings strongly suggest that BI-1 reduces extracellular pH and regulates metastasis by altering glucose metabolism and activating NHE , with the C-terminal tail having a pivotal role in these processes .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;cellular energetics" } ]

The active vitamin D metabolite 1α,25-dihydroxyvitamin D(3) ( 1,25(OH)(2)D(3) ) regulates gene transcription via its nuclear receptor ( VDR ) , and posttranscriptional regulatory mechanisms of gene expression have also been proposed . We have identified microRNA-22 ( miR-22 ) and several other miRNA species as 1,25(OH)(2)D(3) targets in human colon cancer cells . Remarkably , miR-22 is induced by 1,25(OH)(2)D(3) in a time- , dose- and VDR-dependent manner . In SW480-ADH and HCT116 cells , miR-22 loss-of-function by transfection of a miR-22 inhibitor suppresses the antiproliferative effect of 1,25(OH)(2)D(3) . Additionally , miR-22 inhibition increases cell migration per se and decreases the antimigratory effect of 1,25(OH)(2)D(3) in both cell types . In silico analysis shows a significant overlap between genes suppressed by 1,25(OH)(2)D(3) and miR-22 putative target genes .

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;tumor promoting inflammation" } ]

However , PEUs can induce tumors in subcutaneous implantation sites in rat . We have shown that the different inhibitory potential of gap junctional intercellular communication ( GJIC ) on the surface of the biomaterials , including PEUs , is a key step in determining the tumorigenic potential . Here we show that suppression of a gap junctional protein connexin 43 ( Cx43 ) plays an important role in in vivo tumorigenesis induced by PEUs for the first time and that Cx43 transfection may be an effective strategy for preventing tumorigenesis induced by biomaterials . Rat tumor cell line U41 is derived from tumors in the subcutaneous implantation of PEU films . The GJIC and the expression of Cx43 were suppressed in U41 . The restoration of normal phenotype , such as reduction of growth rate , recovery of contact inhibition and loss of colony formation ability in soft agar , was achieved by Cx43 transfection . These results strongly suggest that suppression of Cx43 expression plays an important role in the development of rat malignant fibrous histiocytoma ( MFHC ) caused by PEUs and that Cx43 transfection is effective for prevention of tumorigenesis induced by PEUs .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

The HER-2 gene encodes a cell-surface growth factor receptor with intrinsic tyrosine kinase activity . Wild-type human HER-2 has been shown to act as a potent oncogene when over-expressed in mouse fibroblasts . Recent data suggest that the mechanism by which HER-2 mediates transformation requires the interaction of the epidermal growth factor ( EGF ) receptor . To test whether overexpression of normal human HER-2 can transform cells independently of the EGF receptor , we have introduced multiple copies of HER-2 into the EGF receptor-negative cell line , NR6 , and have performed assays for both transformation and tumorigenicity . Engineered NR6 cells that overexpress the HER-2 gene product display a highly transformed and tumorigenic phenotype as compared with control cells . Additionally , a monoclonal antibody to the extracellular domain of the HER-2 receptor is able to inhibit the proliferation of the overexpressing cells in vitro as well as tumor growth in vivo . This study provides clear evidence that HER-2-mediated transformation can be achieved independently of the EGF receptor .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

However , the underlying molecular and cellular mechanisms of the anticancer effects of Aurora A kinase inhibition are still not fully understood .

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 .

Recently , it was observed that Compound C , an inhibitor of AMPK , also reduced the cell viability in human diploid fibroblasts ( HDFs ) . Compound C-induced growth arrest was associated with a decrease in the cell cycle regulatory proteins , such as proliferating cell nuclear antigen , phosphorylated pRB , cyclin-dependent protein kinases ( Cdk 2 and 4 ) , cyclins ( D and E ) , and the Cdk inhibitors ( p21 , p16 , and p27 ) . Therefore , the present study examined the molecular mechanism of the antiproliferative effects of Compound C. Although Compound C inhibited serum-induced phosphorylation of Akt and its substrate , glycogen synthase kinase-3β , it did not affect the Akt activity in vitro . Compound C significantly inhibited the receptor tyrosine phosphorylation and the activity of downstream signaling molecules , such as p85 phosphoinositide 3-kinase , phospholipase C-γ1 , and extracellular signal-regulated kinase 1/2 , induced by platelet-derived growth factor ( PDGF ) but not by epidermal growth factor- and insulin-like growth factor . In vitro growth factor receptor tyrosine kinase activity profiling revealed the IC(50) for PDGF receptor-β ( PDGFRβ ) to be 5.07 μM , whereas the IC(50) for the epidermal growth factor receptor and insulin-like growth factor receptor was ≥100 μM . The inhibitory effect of Compound C on PDGFRβ and Akt was also observed in AMPKα(1)/α(2)-knockout mouse embryonic fibroblasts , indicating that its inhibitory effect is independent of the AMPK activity . The inhibitory effect of Compound C on cell proliferation and PDGFRβ tyrosine phosphorylation was also demonstrated in various PDGFR-expressing cells , including MRC-5 , BEAS-2B , rat aortic vascular smooth muscle cells , and A172 glioblastoma cells . These results indicate that Compound C can be used as a potential antiproliferative agent for PDGF- or PDGFR-associated diseases , such as cancer , atherosclerosis , and fibrosis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

A small fraction of a cell's glucose enters the hexosamine biosynthetic pathway ( HBP ) , which regulates levels of O-linked beta-N-acetylglucosamine ( O-GlcNAc ) , a carbohydrate posttranslational modification of diverse nuclear and cytosolic proteins . We discovered that breast cancer cells upregulate the HBP , including increased O-GlcNAcation and elevated expression of O-GlcNAc transferase ( OGT ) , which is the enzyme catalyzing the addition of O-GlcNAc to proteins . Reduction of O-GlcNAcation through RNA interference of OGT in breast cancer cells leads to inhibition of tumor growth both in vitro and in vivo and is associated with decreased cell-cycle progression and increased expression of the cell-cycle inhibitor p27(Kip1) . Elevation of p27(Kip1) was associated with decreased expression and activity of the oncogenic transcription factor FoxM1 , a known regulator of p27(Kip1) stability through transcriptional control of Skp2 . Reducing O-GlcNAc levels in breast cancer cells decreased levels of FoxM1 protein and caused a decrease in multiple FoxM1-specific targets , including Skp2 . Moreover , reducing O-GlcNAcation decreased cancer cell invasion and was associated with the downregulation of matrix metalloproteinase-2 , a known FoxM1 target . Finally , pharmacological inhibition of OGT in breast cancer cells had similar anti-growth and anti-invasion effects . These findings identify O-GlcNAc as a novel mechanism through which alterations in glucose metabolism regulate cancer growth and invasion and suggest that OGT may represent novel therapeutic targets for breast cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;cellular energetics" } ]

Primary murine and murine embryonic EPCs ( eEPCs ) were analyzed for the expression of angiogenic/chemokines and components of the MIF/CXC chemokine receptor axis , focusing on the influence of hypoxic versus normoxic stimulation . Hypoxia induced an upregulation of CXCR2 and CXCR4 but not CD74 on EPCs and triggered the secretion of CXCL12 , CXCL1 , MIF , and vascular endothelial growth factor ( VEGF ) . These factors stimulated the transmigration activity and adhesive capacity of EPCs , with MIF and VEGF exhibiting the strongest effects under hypoxia . MIF- , VEGF- , CXCL12- , and CXCL1-stimulated EPCs enhanced tube formation , with MIF and VEGF exhibiting again the strongest effect following hypoxia . Tube formation following in vivo implantation utilizing angiogenic factor-loaded Matrigel plugs was only promoted by VEGF . Coloading of plugs with eEPCs led to enhanced tube formation only by CXCL12 , whereas MIF was the only factor which induced differentiation towards an endothelial and smooth muscle cell ( SMC ) phenotype , indicating an angiogenic and differentiation capacity in vivo . Surprisingly , CXCL12 , a chemoattractant for smooth muscle progenitor cells , inhibited SMC differentiation . We have identified a role for EPC-derived proangiogenic MIF , VEGF and MIF receptors in EPC recruitment following hypoxia , EPC differentiation and subsequent tube and vessel formation , whereas CXCL12 , a mediator of early EPC recruitment , does not contribute to the remodeling process . By discerning the contributions of key angiogenic chemokines and EPCs , these findings offer valuable mechanistic insight into mouse models of angiogenesis and help to define the intricate interplay between EPC-derived angiogenic cargo factors , EPCs , and the angiogenic target tissue .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

To better understand the precise molecular mechanism(s) by which genistein exerts its effects on PC3 cells , we utilized cDNA microarray to interrogate 12,558 known genes to determine the gene expression profiles altered by genistein treatment . We found a total of 832 genes that showed a greater than twofold change after genistein treatment from two independent experiments with a high degree of concordance . Among these genes , 774 genes were down-regulated and 58 genes were up-regulated with genistein treatment . Cluster analysis showed nine different types of expression alternations . These genes were also subjected to cluster analysis according to their biological functions . We found that genistein regulated the expression of genes that are critically involved in the regulation of cell growth , cell cycle , apoptosis , cell signaling transduction , angiogenesis , tumor cell invasion and metastasis . Reverse transcription-polymerase chain reaction ( RT-PCR ) analysis was used to confirm the results of cDNA microarray , and the results of RT-PCR were consistent with the microarray data . We conclude that genistein affected the expression of a large number of genes that are related to the control of cell survival and physiologic behaviors . The gene expression profiles provide comprehensive molecular mechanism(s) by which genistein exerts its pleiotropic effects on cancer cells .

However , studies elucidating the role and the mechanism(s) of action of hesperetin in cervical cancer are sparse . In this study , we investigated the mechanism of the antiproliferative and apoptotic actions exerted by hesperetin on human cervical cancer SiHa cells . The viability of SiHa cells was evaluated using the MTT assay , apoptosis by acridine orange/ethidium bromide , propidium iodide , TUNEL assay , and Annexin V-Cy3 , cell cycle distribution and mitochondrial transmembrane potential using flow cytometry , and apoptotic marker genes using quantitative real-time PCR . The treatment of SiHa cells with hesperetin ( IC(50,) 650μm ) showed a marked concentration- and time-dependent inhibition of proliferation and induced the G2/M phase in a dose-dependent manner after 24h . There was an attenuation of mitochondrial membrane potential with increased expression of caspase-3 , caspase-8 , caspase-9 , p53 , Bax , and Fas death receptor and its adaptor protein Fas-associated death domain-containing protein ( FADD ) , indicating the participation of both death receptor- and mitochondria-related mechanisms . Furthermore , hesperetin-induced apoptosis was confirmed by TUNEL and Annexin V-Cy3 .

Relevant mouse models are powerful for untangling this problem because such heterogeneity can be controlled . Inbred Chaos3 mice exhibit high levels of genomic instability leading to mammary tumors that have tumor gene expression profiles closely resembling mature human mammary luminal cell signatures . We genomically characterized mammary adenocarcinomas from these mice to identify cancer-causing genomic events that overlap common alterations in human breast cancer . Chaos3 tumors underwent recurrent copy number alterations ( CNAs ) , particularly deletion of the RAS inhibitor Neurofibromin 1 ( Nf1 ) in nearly all cases . These overlap with human CNAs including NF1 , which is deleted or mutated in 27.7% of all breast carcinomas . Chaos3 mammary tumor cells exhibit RAS hyperactivation and increased sensitivity to RAS pathway inhibitors . These results indicate that spontaneous NF1 loss can drive breast cancer . This should be informative for treatment of the significant fraction of patients whose tumors bear NF1 mutations .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Vice versa , transformed cells are characterised by a loss of contact-inhibition . Despite its generally accepted importance for cell-cycle control , little is known about the intracellular signalling pathways involved in contact-inhibition . Unravelling the molecular mechanisms of contact-inhibition and its loss during tumourigenesis will be an important step towards the identification of novel target genes in tumour diagnosis and treatment . To better understand the underlying molecular mechanisms we identified the transcriptional programme of contact-inhibition in NIH3T3 fibroblast using high-density microarrays . Setting the cut off : >or=1.5-fold , P <or= 0.05 , 853 genes and 73 cDNA sequences were differentially expressed in confluent compared to exponentially growing cultures . Importing these data into GenMAPP software revealed a comprehensive list of cell-cycle regulatory genes mediating G0/G1 arrest , which was confirmed by RT-PCR and Western blot . In a narrow analysis ( cut off : >or=2-fold , P <or= 0.002 ) , we found 110 transcripts to be differentially expressed representing 107 genes and 3 cDNA sequences involved , for example , in proliferation , signal transduction , transcriptional regulation , cell adhesion and communication . Interestingly , the majority of genes was upregulated indicating that contact-inhibition is not a passive state , but actively induced . Furthermore , we confirmed differential expression of eight genes by semi-quantitative RT-PCR and identified the potential tumour suppressor transforming growth factor-beta ( TGF-beta)-1-induced clone 22 ( TSC-22 ; tgfb1i4 ) as a novel protein to be induced in contact-inhibited cells .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

We also estimated serum cytokines as biomarkers to distinguish preoperatively between malignant or benign character of tumors . DESIGN Prospective study . SETTING Tertiary referral hospital . POPULATION 51 women with epithelial ovarian cancer , 26 with benign ovarian tumors of epithelial origin and 21 healthy controls . METHODS The levels of cytokines were measured using ELISA sets . RESULTS We did not found differences in the levels of IFN-gamma , TNF-alpha and IL-2 in all fluids isolated from patients with malignant or benign tumors . Women with advanced cancer had significantly higher serum IL-6 , IL-10 and TGF-beta1 levels than women with early stages or benign tumors . Moreover , women with very advanced cancer in whom the optimal cytoreduction was disabled had the highest serum levels of IL-10 , TGF-beta1 and IL-8 . The concentrations of IL-6 and IL-8 were higher in ascites of cancer patients than in ascites of women with benign tumors . The areas under curves constructed for the selected cutoff serum cytokines levels ( AUC-ROC ) showed good predictive values for IL-6 ( 0.87 ) , IL-10 ( 0.836 ) and IL-8 ( 0.797 ) . CONCLUSIONS Our results indicate on intensified inflammatory process in women with ovarian cancer ( accompanied by their immunosuppression ) .

EBNA3C was previously shown to target pRb for ubiquitin-proteasome mediated degradation , which facilitates G1 to S transition controlled by the major transcriptional activator E2F1 . E2F1 also plays a pivotal role in regulating DNA damage induced apoptosis through both p53-dependent and -independent pathways . In this study , we demonstrate that in response to DNA damage LCLs knocked down for EBNA3C undergo a drastic induction of apoptosis , as a possible consequence of both p53- and E2F1-mediated activities . Importantly , EBNA3C was previously shown to suppress p53-induced apoptosis . Now , we also show that EBNA3C efficiently blocks E2F1-mediated apoptosis , as well as its anti-proliferative effects in a p53-independent manner , in response to DNA damage . The N- and C-terminal domains of EBNA3C form a stable pRb independent complex with the N-terminal DNA-binding region of E2F1 responsible for inducing apoptosis . Mechanistically , we show that EBNA3C represses E2F1 transcriptional activity via blocking its DNA-binding activity at the responsive promoters of p73 and Apaf-1 apoptosis induced genes , and also facilitates E2F1 degradation in an ubiquitin-proteasome dependent fashion . Moreover , in response to DNA damage , E2F1 knockdown LCLs exhibited a significant reduction in apoptosis with higher cell-viability . In the presence of normal mitogenic stimuli the growth rate of LCLs knockdown for E2F1 was markedly impaired ; indicating that E2F1 plays a dual role in EBV positive cells and that active engagement of the EBNA3C-E2F1 complex is crucial for inhibition of DNA damage induced E2F1-mediated apoptosis . This study offers novel insights into our current understanding of EBV biology and enhances the potential for development of effective therapies against EBV associated B-cell lymphomas .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;resisting cell death" } ]

Unfortunately , hormone-independent estrogen receptor negative ( ER- ) breast cancers are aggressive , respond poorly to current treatments and have a poor prognosis . New approaches and targets are needed for the prevention and treatment of ER- breast cancer . The NF-κB signaling pathway is strongly implicated in ER- tumor genesis , constituting a possible target for treatment . Hydrogen sulfide-releasing aspirin ( HS-ASA ) , a novel and safer derivative of aspirin , has shown promise as an anti-cancer agent . We examined the growth inhibitory effect of HS-ASA via alterations in cell proliferation , cell cycle phase transitions , and apoptosis , using MDA-MB-231 cells as a model of triple negative breast cancer . Tumor xenografts in mice , representing human ER- breast cancer , were evaluated for reduction in tumor size , followed by immunohistochemical analysis for proliferation , apoptosis and expression of NF-κB . HS-ASA suppressed the growth of MDA-MB-231 cells by induction of G(0)/G(1) arrest and apoptosis , down-regulation of NF-κB , reduction of thioredoxin reductase activity , and increased levels reactive oxygen species . Tumor xenografts in mice , were significantly reduced in volume and mass by HS-ASA treatment . The decrease in tumor mass was associated with inhibition of cell proliferation , induction of apoptosis and decrease in NF-κB levels in vivo .

Such an approach may assist in the study of cancer drug resistance and in establishing parameters for assessing human populations for sensitivity to DNA damaging agents in the environment . Platinum-DNA adduct levels were measured by atomic absorbance spectrometry . DNA repair capacity was assessed in human T-lymphocytes by the ability to repair cisplatin lesions in cellular DNA or in transfected plasmid DNA . In a \" blinded \" study of 21 patients receiving combination cisplatin/carboplatin drug therapy , there was a direct relationship between DNA damage in leukocytes and disease response ( summary two-sided p = 0.00011 ) . The cohort of patients had 15 different tumor types , suggesting that blood tissue and tumor tissue of an individual may process platinum-DNA damage similarly regardless of the tissue of origin of the tumor . In leukocytes in vivo , persistence and accumulation were prominent features of the cisplatin-DNA adduct profile . Functional DNA repair capacity has been studied in eight human leukocyte cell lines in vitro ( three , T-cells ; three , B-cells ; one , monocytic ; one , promyelocytic ) , using a host cell reactivation assay with cisplatin-damaged pRSVcat . In the three T cell lines studied , host cell reactivation efficiency was directly related to the cells ' abilities to repair cisplatin-damaged cellular DNA ( correlation coefficient = 0.993).(ABSTRACT TRUNCATED AT 250 WORDS )\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

METHODS : To test the converse hypothesis that inhibition of endogenous IGFBP-6 secretion stimulates Caco-2 cell proliferation , cells were transfected with the antisense IGFBP-6 expression construct or pcDNA3 vector only , and single colonies resistant to G418 sulfate were isolated . RESULTS : Our initial studies indicated that three antisense clones grew faster and produced less IGFBP-6 than two pcDNA3 clones , so antisense IGFBP-6 #5 and pcDNA3 #8 were selected for further detailed analysis . Both the control and antisense clones grew in serum-free medium reaching a plateau density at day eight . However , the antisense clone grew at a rate faster than that of the control and reached a final density that was 31 +/- 3% higher than the control . Northern blot , ligand blot and immunoblot analyses revealed that accumulation of IGFBP-6 mRNA and concentrations of IGFBP-6 peptide produced by the antisense clone were decreased by 80-90% compared to the control . The doubling times of the antisense and control clones were 21.9 +/- 0.4 and 24.8 +/- 0.3 h ( P &lt ; 0.05 ) , respectively . Exogenous IGF-I and IGF-II ( 0.2-200 nmol/L ) stimulated proliferation of both the control and antisense clones in a dose-dependent manner , but the relative potency and efficacy of IGF-II was higher in the antisense clone compared to the control . These results indicate that suppression of IGFBP-6 secretion correlates with an increase in the basal rate of Caco-2 cell growth . CONCLUSIONS : Our findings are consistent with the hypothesis that IGFBP-6 inhibits cell growth by binding to endogenously produced IGF-II , thereby preventing IGF-II from interacting with the IGF-I receptor to stimulate cellular proliferation by an autocrine mechanism .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

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 .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;activating invasion and metastasis" } ]

Work from our laboratory demonstrated that a single treatment with N-methyl-N'-nitro-N-nitrosoguanidine ( MNNG ) enhanced spontaneous malignant transformation of the human keratinocyte cell line RHEK-1 . In contrast , chronic low-level exposure of cells to arsenic alone or in a mixture containing arsenic , cadmium , chromium , and lead inhibited malignant conversion . To identify changes in gene expression that influence these different outcomes , cDNA microarray technology was used . Analysis of multiple human arrays in MNNG-transformed RHEK-1 cells , designated OM3 , and those treated with arsenic or the arsenic-containing metal mixture showed unique patterns of gene expression . Genes that were overexpressed in OM3 included oncogenes , cell cycle regulators , and those involved in signal transduction , whereas genes for DNA repair enzymes and inhibitors of transformation and metastasis were suppressed . In arsenic-treated cells , multiple DNA repair proteins were overexpressed . Mixture-treated cells showed increased expression of a variety of genes including metallothioneins and integrin 4 . These cells showed decreased expression of oncogenes , DNA repair proteins , and genes involved in the mitogen-activated protein kinase pathway . For comparison we are currently analyzing gene expression changes in RHEK-1 cells transformed by other means . The goal of these studies is to identify common batteries of genes affected by chemical modulators of the carcinogenic process .

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.\n OUTPUT: sustaining proliferative signaling;resisting cell death\n\n 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 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

Here , we show that PRL , though it failed to activate mouse peritoneal resident macrophages ( RMs ) , acted as a second signal and activated mouse peritoneal inflammatory macrophages ( EMs ) to a tumoricidal state . The cytotoxicity of mouse tumor-associated macrophages ( TAMs ) isolated at day 1 of tumor ( Ehrlich ascites carcinoma , EAC ) growth was enhanced by PRL . However , with progression of tumor growth , TAMs became nonresponsive to the hormone . PRL-induced killing of P815 target cells by EMs and TAMs was independent of TNF but correlated with the hormone-induced augmentation of NO2(-) and O2(-) release in these macrophages . Administration of PRL in vivo inhibited EAC growth and augmented NO2(-) release by TAMs . PRL synergized with the TH1 cytokine IFN-gamma , a known activator of macrophages , in inducing tumor killing and release of NO2(-) from EMs and TAMs . The hormone might activate macrophages at least partially , through the release of IFN-gamma as anti-IFN-gamma blocked IFN-gamma- as well as PRL-induced cytotoxicity in EMs . The TH2 cytokine IL-4 suppressed PRL-induced activation of macrophages . PRL induced release of IL-12 from EMs also , which suggested that the hormone might drive the TH1 response through IL-12 . Our observations further suggest that PRL alone and in synergy with IFN-gamma , released through induction of IL-12 , may generate tumoricidal macrophages and thus regulate the antitumor immune response of tumor hosts .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

Nuclear protein 7 ( NOL7 ) , a novel tumor suppressor , acts as a master regulator of angiogenesis by downregulating pro-angiogenic factors and upregulating anti-angiogenic factors . Using cervical cancer as a model of investigation , we have previously shown that loss of NOL7 mRNA and protein expression is observed as early as the premalignant phase . Analysis of the gene failed to identify tumor-specific promoter methylation or coding region mutations , suggesting that NOL7 loss may be mediated by aberrant expression of its upstream regulators . In this study , we show that the RB tumor suppressor gene ( RB ) positively regulates NOL7 at the transcriptional level by recruiting transcription factors and transcription machinery proteins to its promoter region . Conversely , the loss of RB represses NOL7 transcription by inhibiting assembly of these proteins . This loss of NOL7 expression is also observed in RB-deficient human malignancies . Together , this work further characterizes the transcriptional activator function of RB and defines a potential role for RB in regulating angiogenesis through activation of NOL7 . Current anti-angiogenic therapies lack long-term efficacy , as they are unable to target the diverse angiogenic signals generated by tumors . Our data provide evidence to support the hypothesis that reactivation of pRB can potentially modulate the expression of the angiogenic phenotype through regulation of NOL7 . Therefore , this knowledge may be employed to design more comprehensive and effective therapies .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

The data show that trans-[PtCl2(NH(CH)2)(NHCH(CH3)2)] is able to circumvent resistance to cis-[PtCl2(NH3)2] ( cis-DDP , cisplatin ) in A2780cisR cells . In fact , trans-[PtCl2(NH(CH3)2)(NHCH(CH3)2)] shows a cytotoxic potency higher than that of cis-DDP and trans-DDP , with the mean IC50 values being 11 , 58 , and 300 microM , respectively . In addition , at equitoxic doses ( concentrations of the platinum drugs equal to their IC50 values ) and after 24 hours of drug treatment , the level of induction of apoptosis by trans-[PtCl2(NH(CH3)2)(NHCH(CH3)2)] is twice that produced by cis-DDP . Under the same experimental conditions , trans-DDP does not induce significant levels of apoptosis in A2780cisR cells . After 24 hours of incubation of A2780cisR cells at concentrations equal to the IC0o value of the platinum drugs , the level of DNA interstrand cross-links ( ICLs ) induced by trans-[PtCI2(NH(CH)2)(NHCH(CH3)] is two and three times higher , respectively , than those induced by cis-DDP and trans-DDP . We also found that trans-[PtCl2(NH(CH3)2)(NHCH(CH3)2)] formed DNA ICLs between guanine and complementary cytosine . We propose that , in A2780cisR cells , the induction of apoptosis by trans-[PtCl2(NH(CH3)2)(NHCH(CH3)2)] is related to its greater ability ( relative to cis-DDP and trans-DDP ) to form DNA ICLs .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;genomic instability and mutation" } ]
