Because several filamin-A interaction partners are implicated in signaling of cell mobility regulation , we tested the hypothesis that filamin-A plays a role in cancer metastasis . Using four pairs of filamin-A proficient and deficient isogenic cell lines , we found that filamin-A deficiency in cancer cells significantly reduces their migration and invasion . Using a xenograft tumor model with subcutaneous and intracardiac injections of tumor cells , we found that the filamin-A deficiency causes significant reduction of lung , splenic and systemic metastasis in nude mice . We evaluated the expression of filamin-A in breast cancer tissues by immunohistochemical staining , and found that low levels of filamin-A expression in cancer cells of the tumor tissues are associated with a better distant metastasis-free survival than those with normal levels of filamin-A . These data not only validate filamin-A as a prognostic marker for cancer metastasis , but also suggest that inhibition of filamin-A in cancer cells may reduce metastasis and that filamin-A can be used as a therapeutic target for filamin-A positive cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

Steps of angiogenesis are energy consuming , while vascular endothelial cells are highly glycolytic . Glioblastoma multiforme ( GBM ) is a highly vascular tumor and this enhances its aggressiveness . D-amino acid oxidase ( DAO ) is a promising therapeutic protein that induces oxidative stress upon acting on its substrates . Oxidative stress-energy depletion ( OSED ) therapy was recently reported ( El Sayed et al. , Cancer Gene Ther , 19 , 1-18 , 2012 ) . OSED combines DAO-induced oxidative stress with energy depletion caused by glycolytic inhibitors such as 3-bromopyruvate ( 3BP ) , a hexokinase II inhibitor that depleted ATP in cancer cells and induced production of hydrogen peroxide. 3BP disturbs the Warburg effect and antagonizes effects of lactate and pyruvate ( El Sayed et al. , J Bioenerg Biomembr , 44 , 61-79 , 2012 ) . Citrate is a natural organic acid capable of inhibiting glycolysis by targeting phosphofructokinase . Here , we report that DAO , 3BP and citrate significantly inhibited angiogenesis , decreased the number of vascular branching points and shortened the length of vascular tubules . OSED delayed the growth of C6/DAO glioma cells. 3BP combined with citrate delayed the growth of C6 glioma cells and decreased significantly the number and size of C6 glioma colonies in soft agar . Human GBM cells ( U373MG ) were resistant to chemotherapy e.g. cisplatin and cytosine arabinoside , while 3BP was effective in decreasing the viability and disturbing the morphology of U373MG cells .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

Prostate cancer is the most frequently diagnosed malignancy and the second-leading cause of cancer death in men . In spite of the current therapeutic options for this cancer entity , many patients die due to metastases in distant organs and acquired chemotherapy resistance . Thus , approaches to provide improvements in outcome and quality of life for such patients are urgently needed . Recently , the polyisoprenylated benzophenone 7-epi-nemorosone , originally collected by honeybees from Clusia rosea and Clusia grandiflora ( Clusiaceae ) , has been described to be a potent antitumoral agent . Here , its activity in prostate carcinoma is reported. 7-epi-nemorosone was isolated from Caribbean propolis employing RP-HPLC techniques . Its cytotoxicity was assessed using the MTT proliferation assay in human androgen-dependent prostate carcinoma LNCaP cells including an MDR1(+) sub-line . No cross-resistance was detected . FACS-based cell cycle analysis revealed a significant increase in the sub-G0/G1 , G1 , and depletion in the S phase populations . A concomitant down-regulation of cyclins D1/D3 and CDK 4/6 in LNCaP cells was detected by Western blot . Annexin-V-FITC labeling and caspase-3 cleavage assays showed that 7-epi-nemorosone induced apoptotic events . Major signal transduction elements such as p38 MAPK and Akt/PKB as well as androgen receptor AR and PSA production were found to be down-regulated after exposure to the drug . ERK1/2 protein levels and phosphorylation status were down-regulated accompanied by up-regulation but inhibition of the activity of their immediate upstream kinases MEK1/2 . Additionally , Akt/PKB enzymatic activity was effectively inhibited at a similar concentration as for MEK1/2 . Here , we demonstrate for the first time that 7-epi-nemorosone exerts cytotoxicity in an androgen-dependent prostate carcinoma entity by targeting the MEK1/2 signal transducer .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

We conducted this study to advance our understanding of the causes of genomic complexity in CLL . EXPERIMENTAL DESIGN We have obtained quantitative measurements of radiation-induced apoptosis and radiation-induced ATM autophosphorylation in purified CLL cells from 158 and 140 patients , respectively , and have used multivariate analysis to identify independent contributions of various biological variables on genomic complexity in CLL . RESULTS Here , we identify a strong independent effect of radiation resistance on elevated genomic complexity in CLL and describe radiation resistance as a predictor for shortened CLL survival . Furthermore , using multivariate analysis , we identify del17p/p53 aberrations , del11q , del13q14 type II ( invariably resulting in Rb loss ) , and CD38 expression as independent predictors of genomic complexity in CLL , with aberrant p53 as a predictor of approximately 50% of genomic complexity in CLL . Focusing on del11q , we determined that normalized ATM activity was a modest predictor of genomic complexity but was not independent of del11q . Through single nucleotide polymorphism array-based fine mapping of del11q , we identified frequent monoallelic loss of Mre11 and H2AFX in addition to ATM , indicative of compound del11q-resident gene defects in the DNA double-strand break response . CONCLUSIONS Our quantitative analysis links multiple molecular defects , including for the first time del11q and large 13q14 deletions ( type II ) , to elevated genomic complexity in CLL , thereby suggesting mechanisms for the observed clinical aggressiveness of CLL in patients with unstable genomes .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Previous studies have shown that DU has both chemical and radiological toxicity and that the primary route of exposure of DU to humans is through inhalation and ingestion . However , there is limited research information on the potential carcinogenicity of DU in human bronchial cells . Accordingly , we determined the neoplastic transforming ability of particulate DU to human bronchial epithelial cells ( BEP2D ) . We observed the loss of contact inhibition and anchorage independent growth in cells exposed to DU after 24 h . We also characterized these DU-induced transformed cell lines and found that 40% of the cell lines exhibit alterations in plating efficiency and no significant changes in the cytotoxic response to DU . Cytogenetic analyses showed that 53% of the DU-transformed cell lines possess a hypodiploid phenotype . These data indicate that human bronchial cells are transformed by DU and exhibit significant chromosome instability consistent with a neoplastic phenotype .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

SU5416 is a small molecule which inhibits angiogenesis by acting as an inhibitor of VEGF receptor-2 tyrosine kinase . We have developed a reproducible murine model for neuroblastoma , a childhood cancer , based on s.c. xenotransplantation of SH-SY5Y neuroblastoma cells . We found that SH-SY5Y cells expressed VEGF-A on both the mRNA and protein levels , that plasma concentrations of VEGF-A were significantly elevated in animals with neuroblastoma with a volume &gt ; 1.4 ml , and that there was a correlation between VEGF-A levels in plasma and tumor size in untreated tumor-bearing animals . Treatment with SU5416 reduced the growth of neuroblastoma tumors by 65% without apparent toxicity . SU5416 treatment also suppressed tumor angiogenesis , despite an increase in plasma VEGF-A levels per ml tumor volume during therapy .

Thus far , only 11 reports have documented the characteristics of ovarian endometrioid adenocarcinoma cell lines in the literature . Due to the scarcity of information , the establishment of an ovarian malignant tumor cell line with distinctive characteristics is particularly important to study this disease . Thus , this study was undertaken to establish and characterize a new human endometrioid adenocarcinoma cell line of the ovary . METHODS The cell line NOMH-1 was established from an ovarian tumor of a 44-year-old woman . Features of the cell line studied included morphology , chromosome analysis , heterotransplantation , tumor markers , and chemosensitivity . RESULTS This cell line has been growing well for 232 months and subcultured more than 50 times . Monolayer cultured cells were polygonal in shape , showing a pavement-like arrangement and a tendency to stack without contact inhibition . They exhibited a human karyotype with a modal chromosomal number in the hypertriploid range . The cells could be transplanted into the subcutis of nude mice and produced tumors resembling the original tumor . NOMH-1 cells expressed both CEA and CA19-9 which were identified immunohistochemically in the original tumor and the heterotransplanted tumor . The cells were sensitive to paclitaxel , an agent commonly used in the treatment of gynecological cancers . CONCLUSIONS NOMH-1 is the first ovarian endometrioid adenocarcinoma cell line in which CEA and CA19-9 expression have been defined . This newly established cell line should be useful for investigating the characteristics of ovarian endometrioid adenocarcinoma .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

The HPV16 variant was able to extend the lifespan of , but failed to immortalize , human keratinocytes . It could however cooperate with an activated ras oncogene to transform primary rodent cells . Radioimmunoprecipitation assays of the rodent cells showed that they expressed the E7 protein . DNA sequence analysis of the URR/E6/E7 and E5 regions of the HPV16 showed them to be fully functional , but a deletion in the viral E2 open reading frame was detected . This truncated E2 only weakly stimulated transcription of the viral regulatory region . Complementation assays using the HPV16 variant and a full-length E2 enabled the cloned variant to immortalize human cervical keratinocytes with wild-type efficiency . These results suggest that other viral gene products in addition to E6/E7 may play an important role in the in vitro immortalization of cervical keratinocytes in HPV16 and the development of cervical cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

In previous studies , the reported association was based on the estimated average TSP-1 value per tumour , with a sufficient number of specimens collectively analysed per tumour type . Given the extent of intra-tumour heterogeneity , we determined the association between TSP-1 and vascularity within individual specimens , based on the average values of TSP-1 and vascularity in 10-20 pre-selected areas per tumour . Cells expressing TSP-1 mRNA were visualised by in situ hybridisation and quantified by point counting . Vascularity was quantified by point counting and vessel density of von Willebrand Factor-positive vessels . In 10 ductal breast carcinomas , a direct correlation between TSP-1 and vascularity was found in 4 tumours , no correlation in 3 and an inverse correlation in 3 . The effect of TSP-1 on endothelial cell migration in vitro was assessed in the Boyden chamber assay . TSP-1 stimulated cell migration at low concentrations ( 0.1-10 microg/ml ) and was inhibitory at high concentrations ( 25-100 microg/ml ) .

Targeting epidermal growth factor receptor ( EGFR ) is attractive in that it is an early critical event in HNSCC pathogenesis . However , current agents lack efficacy or have unacceptable toxicity . Several groups have demonstrated that the over-the-counter medication , polyethylene glycol ( PEG ) has remarkable chemopreventive efficacy against colon carcinogenesis . Importantly , we reported that this effect is mediated through EGFR internalization/degradation . In the current study , we investigated the chemopreventive efficacy of this agent against HNSCC , using both the well validated animal model 4-NQO ( 4-nitroquinoline 1-oxide ) rat model and cell culture with the human HNSCC cell line SCC-25 . We demonstrated that daily topical application of 10% PEG-8000 in the oral cavity ( tongue and cavity wall ) post 4NQO initiation resulted in a significant reduction in tumor burden ( both , tumor size and tumors/tumor bearing rat ) without any evidence of toxicity . Immunohistochemical studies depicted decreased proliferation ( number of Ki67-positive cells ) and reduced expression of EGFR and its downstream effectors cyclin D1 in the tongue mucosa of 4NQO-rats treated with PEG . We showed that EGFR was also markedly downregulated in SCC-25 cells by PEG-8000 with a concomitant induction of G1-S phase cell-cycle arrest , which was potentially mediated through upregulated p21(cip1/waf1) . In conclusion , we demonstrate , for the first time , that PEG has promising efficacy and safety as a chemopreventive efficacy against oral carcinogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors" } ]

Based on high throughput technologies data , this disease is currently classified according to the molecular expression of estrogen ( ER ) , progesterone ( PR ) and human epidermal growth factor ( HER-2 ) receptors . In this study , we defined the inflammatory profile of the main molecular subtypes of breast cancer patients : luminal ( ER and PR positive , HER-2 negative ) , HER-2 enriched ( HER-2 positive ) and triple negative ( ER , PR and HER-2 negative ) . Cytokines panel was assessed by measurement of TNF-α , TGF-β , IL-1 , IL-10 and IL-12 plasmatic levels . Oxidative profile was assessed by determination of lipid peroxidation , total antioxidant capacity of plasma , malondialdehyde levels , carbonyl content and nitric oxide ( NO ) . Clinical data were correlated with inflammatory findings . Our findings demonstrated that patients bearing the luminal subtype displayed high TNF-α , TGF-β and enhanced oxidative stress levels associated with reduced IL-12 .

Enhanced levels of activated p38 isoforms have been linked with poor prognosis in breast cancer , although the mechanistic basis for this association is poorly understood . In this study , we report that p38 activation in cervical cancer cells is driven by osteopontin ( OPN ) , an extracellular matrix-associated cytokine that drives invasive progression . OPN regulates CD44-mediated p38 phosphorylation that induces NF-κB activation and NF-κB-dependent expression of furin , an extracellular protease implicated in human papilloma virus ( HPV ) processing that enhances cervical cancer cell motility . OPN induces CD44-mediated MKK3/6 phosphorylation which in turn phosphorylates p38 in these cells . OPN-induced furin expression and cell motility was impeded by blockades to MKK3/6 , p38α/β or NF-κB signaling . In a mouse xenograft model of human cervical cancer , tumor growth was enhanced by OPN overexpression and blocked by short hairpin RNA ( shRNA)-mediated OPN silencing . Furin overexpression similarly augmented tumor growth in the model , whereas blocking MKK3/6 , p38 , or furin reduced OPN-induced cervical tumor growth . Analysis of clinical specimens revealed that enhanced expression of OPN , phosphorylated NF-κB , p65 , and furin correlated with cervical cancer progression , further strengthening the in vitro and in vivo results . In summary , our findings offer a proof of concept for targeting OPN and its downstream p38 signaling as a novel therapeutic strategy to manage cervical cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Cytotoxic T lymphocyte-associated antigen 4 ( CTLA-4 ) serves as a negative regulator of immunity . Recent trials administering fully human anti-CTLA-4 monoclonal antibodies to melanoma patients have demonstrated clinically meaningful responses . Treatment with CTLA-4 blocking antibodies , however , is not without potential toxicities . Autoimmune side-effects , the most common being colitis-associated diarrhea , are frequently associated with clinical responses . In efforts to build upon prior vaccination efforts as well as attempt to offer patients clinically meaningful immune responses with a CTLA-4 blockade but without significant toxicities , we conducted a clinical trial in patients who previously received autologous tumor cells engineered to secrete granulocyte-macrophage colony stimulating factor ( GVAX ; Cell Genesys , South San Francisco , CA , USA ) with periodic infusions of CTLA-4 blocking antibodies . This sequential treatment resulted in clinically significant anti-tumor immunity without grade 3 or 4 toxicity in most patients . Pathological analyses following treatment of pre-existing tumors revealed a linear correlation between tumor necrosis and the ratio of intra-tumoral CD8+ effector cells to FoxP3+ regulatory cells ( T(regs) ) . Effective anti-tumor immunity and serious autoimmunity can be disassociated . Further targeting of anti-tumor T(regs)in combinatorial therapy approaches may be a rich avenue of future investigation .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction;resisting cell death" } ]

Phospho-H2A/X ( gammaH2A/X)-binding proteins at double-strand breaks ( DSBs ) have been characterized , but those required for replication stress responses are unknown . Here , we present genetic , biochemical , small angle X-ray scattering ( SAXS ) , and X-ray structural studies of the Schizosaccharomyces pombe Brc1 , a 6-BRCT-domain protein that is structurally related to Saccharomyces cerevisiae Rtt107 and mammalian PTIP . Brc1 binds gammaH2A to form spontaneous and DNA damage-induced nuclear foci . Spontaneous Brc1 foci colocalize with ribosomal DNA repeats , a region prone to fork pausing and genomic instability , whereas DNA damage-induced Brc1 foci colocalize with DSB response factors. gammaH2A binding is critical for Brc1 function . The 1.45 A resolution crystal structure of Brc1-gammaH2A complex shows how variable BRCT insertion loops sculpt tandem-BRCT phosphoprotein-binding pockets to facilitate unique phosphoprotein-interaction specificities , and unveils an acidic DNA-mimicking Brc1 surface . From these results , Brc1 docking to gammaH2A emerges as a critical chromatin-specific response to replication-associated DNA damage .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Less is known about the function of CD8+ Treg cells than about the function of CD4+ Treg cells generated during allergen-specific immunotherapy ( IT ) . This study investigated whether Dermatophagoides pteronyssinus-specific IT could expand the CD8+CD25+Foxp3+ Treg population and whether Pam3CSK4 could enhance the Treg population . PBMCs were isolated from healthy control subjects and from mite-sensitive asthmatic patients during IT at three specific times : before IT and 6 mo and 1 y after the maximum-tolerated dose . This study was performed without a placebo-controlled group . D. pteronyssinus-specific IT induced a significant increase in CD8+Foxp3+ Treg cells expressing intracellular IL-10 and granzyme B. Costimulation of PBMCs with Pam3CSK4 and D. pteronyssinus 2 expanded the CD8+CD25+Foxp3+ Treg population and inhibited D. pteronyssinus 2-induced IL-4 production . Pam3CSK4-treated CD8+CD25+ Treg cells directly suppressed CD4+ T cell proliferation by cell-contact inhibition . TUNEL revealed that CD8+CD25+ Treg cells , but not CD4+CD25+ Treg cells , directly induced CD4+CD45ROhi+ apoptosis . Our results provide direct evidence that Pam3CSK4 induces an immunomodulatory effect by inducing CD8+ Treg cells ; therefore , it may be a good adjuvant for the treatment of mite allergies .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;resisting cell death" } ]

EXPERIMENTAL DESIGN Primary lung tumors and normal lung tissue were analyzed for expression and localization of estrogen receptor α and β-1 ( ERα and ERβ ) , aromatase , progesterone receptor ( PR ) , and epidermal growth factor receptor ( EGFR ) . RESULTS Tumors expressed higher levels of ERβ compared to matched normal lung , whereas the reverse was true of PR . High cytoplasmic ERβ expression was identified as an independent negative prognostic predictor of overall survival ( OS ; HR = 1.67 ) , and low total PR was identified as an independent negative predictor of time to progression ( TTP ; HR = 1.59 ) . After adjusting for stage , age , sex , and smoking , combined high cytoplasmic ERβ and low total PR showed enhanced effects on OS ( HR = 2.64 ) and on TTP ( HR = 6.02 ) . Further effects on OS were observed when EGFR expression was included ( HR = 5.32 ) . Patients with low cytoplasmic ERβ , low aromatase , low EGFR , and high total PR had shorter OS than patients with the opposite pattern ( HR = 6.60 ) . Contribution of these markers to survival showed no significant sex differences in a multivariable model . ERα was elevated in tumors but was not predictive of survival , and appears to represent a variant ERα protein that is only recognized by a C-terminal antibody . CONCLUSIONS Hormonal and EGFR pathways together may contribute to lung cancer prognosis . Lung tumors with high ERβ-1/low PR may define patients with aggressive biology . A validation study is necessary to fully assess the predictive value of these markers .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

The expression of peroxisome proliferator-activated receptor-gamma mRNA and protein in human chondrosarcoma cell line OUMS-27 was also determined by reverse transcription-polymerase chain reaction and immunocytochemistry , respectively . Furthermore , the effects of peroxisome proliferator-activated receptor-gamma ligands on cell proliferation and survival were investigated in OUMS-27 cells . Pioglitazone , a selective ligand for peroxisome proliferator-activated receptor-gamma , and 15-deoxy-Delta(12,14)-prostaglandin J(2) ( 15d-PGJ(2) ) , a putative endogenous ligand for peroxisome proliferator-activated receptor-gamma , inhibited the proliferation of OUMS-27 cells in a dose-dependent manner . The mechanism of cytotoxic effects of 15d-PGJ(2) was via apoptosis as shown by DNA fragmentation using TUNEL stain and DNA ladder formation , and by ultrastructural analysis using transmission electron microscopy . Flow-cytometric analysis using annexin-V-fluorescein and propidium iodide detected the early change of apoptosis , as well as necrosis of OUMS-27 cells at 4 h after co-incubation with 15d-PGJ(2) . These results suggest that peroxisome proliferator-activated receptor-gamma may play a significant role in the pathogenesis of chondrosarcoma , and peroxisome proliferator-activated receptor-gamma ligands , especially 15d-PGJ(2) , may be of therapeutic value in the treatment of human chondrosarcoma .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

In this study , we report that the latest member of the C-X-C-type chemokines , CXCL17 ( DMC/VCC-1 ) , recruits immature myeloid-derived cells and enhances early tumor progression . METHODOLOGY/PRINCIPAL FINDINGS CXCL17 was preferentially expressed in some aggressive types of gastrointestinal , breast , and lung cancer cells . CXCL17 expression did not impart NIH3T3 cells with oncogenic potential in vitro , but CXCL17-expressing NIH3T3 cells could form vasculature-rich tumors in immunodeficient mice . Our data showed that CXCL17-expressing tumor cells increased immature CD11b(+)Gr1(+) myeloid-derived cells at tumor sites in mice and promoted CD31(+) tumor angiogenesis . Extensive chemotactic assays proved that CXCL17-responding cells were CD11b(+)Gr1(high)F4/80(-) cells ( ≈ 90% ) with a neutrophil-like morphology in vitro . Although CXCL17 expression could not increase the number of CD11b(+)Gr1(+) cells in tumor-burdened SCID mice or promote metastases of low metastatic colon cancer cells , the existence of CXCL17-responding myeloid-derived cells caused a striking enhancement of xenograft tumor formation . CONCLUSIONS/SIGNIFICANCE These results suggest that aberrant expression of CXCL17 in tumor cells recruits immature myeloid-derived cells and promotes tumor progression through angiogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis;activating invasion and metastasis" } ]

Plk3 physically interacts with p53 and phosphorylates this tumor suppressor protein on serine-20 , suggesting that the role of Plk3 in cell cycle progression is mediated , at least in part , through direct regulation of p53 . Here we show that Plk3 is rapidly activated by reactive oxygen species in normal diploid fibroblast cells ( WI-38 ) , correlating with a subsequent increase in p53 protein level . Plk3 physically interacts with Chk2 and the interaction is enhanced upon DNA damage . In addition , Chk2 immunoprecipitated from cell lysates of Daudi ( which expressed little Plk3 ) is capable of stimulating the kinase activity of purified recombinant Plk3 in vitro , and this stimulation is more pronounced when Plk3 is supplemented with Chk2 immunoprecipitated from Daudi after DNA damage .

The purpose of this study was to analyze whether blocking this receptor with the anti-EGFR chimeric monoclonal antibody C225 would decrease proliferation and increase apoptosis in GBM cells . METHODS EGFR expression and amplification were analyzed for seven human GBM cell lines . These lines were then exposed to different concentrations of C225 for 48 hours , 72 hours , and 7 days , after which time cytotoxicity , apoptosis , and vascular endothelial growth factor expression were assessed in vitro . Two EGFR-amplified human GBM were implanted in the flanks of nude mice , and the animals received C225 twice per week intraperitoneally for 5 weeks . Tumor volumes and survival times were compared with those of sham-treated mice . RESULTS EGFR gene amplification was demonstrated in three of the primary GBM lines . C225 treatment produced significant cytotoxicity in all three EGFR-amplified GBM lines , but not in unamplified lines . Flow cytometry demonstrated increased apoptosis in C225-treated , EGFR-amplified GBM lines , but not in unamplified lines . There was a decrease in vascular endothelial growth factor expression in all GBM lines with exposure to C225 . Tumor-bearing mice treated with C225 experienced significant inhibition of tumor growth as well as a 200% increase in median survival . CONCLUSION Blocking EGFR in GBM cells that overexpress this receptor significantly changes tumor cell biology by promoting apoptosis while decreasing proliferation and vascular endothelial growth factor expression . This approach holds great promise for the treatment of patients with GBMs .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death;inducing angiogenesis" } ]

Genetic polymorphisms and differences at the level of transcription in genes involved in biological processes of drug metabolism , DNA repair and drug resistance can explain the observed individual differences in response to drugs , in survival and in different susceptibility to the toxic effects of CT . The possibility to classify patients on the basis of genetic signatures could help in choosing the CT regimen . We present herein an analysis of genetic and expression profiling of three patients affected by metastatic gastric cancer , treated with CT and alive , disease-free , at 66-82 months . Four patients with typical clinical outcome represented the control group . Expression profiling from paraffin-embedded tumor tissues was performed on an ad hoc set of genes involved in drug metabolism and resistance , DNA repair , cell cycle regulation and growth factors signalling . Genetic polymorphism analysis on DNA extracted from peripheral blood was done by pyrosequencing of genetic markers predictive of drug response . Expression analysis in long-term survivors revealed a significant upregulation of PTEN , TP63 , GADD45a and MAPK1 genes . We found also an upregulation of CYP1A1 , CYP3A4 and ERBB4 genes . EGF was found to be down-regulated in long-term survivors . ERCC1 C8092A polymorphism seems to be associated with survival in our set of patients .

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

Our previous studies have suggested that increased angiotensin II ( Ang II)-forming chymase may be involved in the development of atherosclerosis . However , the regulatory mechanism of chymase expression has not yet been clarified . In this study , we tested whether oxidative stress upregulates mouse mast cell proteinase chymase , mouse mast cell proteinase ( MMCP)-5 or MMCP-4 . We also examined the expression and activity of these proteins after treatment . Cultured mouse mastocytoma cells ( MMC ) displaying chymase-dependent Ang II-forming activity were treated with H(2)O(2) and several aminothiols with or without anti-oxidants . The levels of MMCP-5 and MMCP-4 expression were determined by quantitative RT-PCR ; the level of chymase-dependent Ang II-forming activity was measured by high performance liquid chromatography using Ang I as a substrate . Treatment of MMC with homocysteine ( 0.1-3 mmol l(-1) ) significantly increased MMCP-5 and MMCP-4 expression , as well as Ang II-forming activity . These effects were significantly inhibited by the addition of catalase and further suppressed by the combination of catalase and superoxide dismutase . Incubation with hydrogen peroxide alone caused a significant increase in Ang II-forming activity , which was completely suppressed by co-treatment with catalase . Furthermore , MMCP-5 and MMCP-4 expression levels were drastically suppressed and chymase induction by homocysteine was diminished under the GATA-inhibited condition . Homocysteine increased mast cell chymase expression and activity through the mechanism of oxidative stress . Our results suggest that there is a biochemical link between oxidative stress and the local Ang II-forming system .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

They are particularly aggressive , are frequently chemo-resistant , with p53 mutation , up-regulation of IL-6 and Stat3 . Because TN cells are particularly sensitive to the anti-diabetic agent metformin , we hypothesized that it may target JAK2/Stat3 signaling . The effects of metformin upon Stat3 expression and activation were examined in four human TN cell lines . Metformin's effects were also studied in sublines with forced over-expression of constitutively active ( CA ) Stat3 , as well as lines with stable knockdown of Stat3 . Metformin inhibited Stat3 activation ( P-Stat3 ) at Tyr705 and Ser727 and downstream signaling in each of the four parental cell lines . CA-Stat3 transfection attenuated , whereas Stat3 knockdown enhanced , the effects of metformin upon growth inhibition and apoptosis induction . A Stat3 specific inhibitor acted synergistically with metformin in reducing cell growth and inducing apoptosis . An mTOR inhibitor showed no significant interaction with metformin .

The EGF gene presents a polymorphism at position 61 ( A/G ) , associated with higher EGF production . We examined the association between this polymorphism and cervical cancer through a case-control study . METHODS This study used the PCR-restriction fragment length polymorphism method on a sample of 384 women with cervical lesions and 500 controls of white ethnicity . RESULTS In cases of cervical cancer , we found an increased risk of progression to advanced disease ( The International Federation of Gynecology and Obstetrics stage IIb/IV ) ( odds ratios=2.05 ; 95% confidence intervals=1.11 to 3.79 ; P=0.021 ) , and this risk was particularly evident in G carriers for younger women ( odds ratios=2.96 ; 95% confidence intervals=1.41-6.20 , P=0.003 ) . CONCLUSIONS We hypothesize the onset of an advanced disease-driven selective pressure due to the effect of oncogenic human papillomavirus types in a favorable genetic background observed in G carrier women . These results suggest that EGF functional polymorphism may influence cervical cancer prognosis through an EGF/epidermal growth factor receptor pathway .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Under the OXPHOS suppression , AMP-activated protein kinase ( AMPK ) regulates global metabolism adjustments , but its activation has been found to be transient . Whether cells can maintain cellular ATP homeostasis and survive beyond the transient AMPK activation is not known . Here , we study the bioenergetic adaptation to the OXPHOS inhibitor oligomycin in a group of cancer cells . We found that oligomycin at 100 ng/ml completely inhibits OXPHOS activity in 1 h and induces various levels of glycolysis gains by 6 h , from which we calculate the bioenergetic organizations of cancer cells . In glycolysis-dominant cells , oligomycin does not induce much energy stress as measured by glycolysis acceleration , ATP imbalance , AMPK activation , AMPK substrate acetyl-CoA carboxylase phosphorylation at Ser(79) , and cell growth inhibition . In OXPHOS-dependent LKB1 wild type cells , oligomycin induces 5-8% ATP drops and transient AMPK activation during the initial 1-2 h . After AMPK activation is completed , oligomycin-induced increase of acetyl-CoA carboxylase phosphorylation at Ser(79) is still detected , and cellular ATP is back at preoligomycin treatment levels by sustained elevation of glycolysis . Cell growth , however , is inhibited without an increase in cell death and alteration in cell cycle distribution . In OXPHOS-dependent LKB1-null cells , no AMPK activation by oligomycin is detected , yet cells still show a similar adaptation . We also demonstrate that the adaptation to oligomycin does not invoke activation of hypoxia-induced factor . Our data suggest that cancer cells may grow and survive persistent OXPHOS suppression through an as yet unidentified regulatory mechanism .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

CSR is completed by joining a DSB in the donor S mu to a DSB in a downstream acceptor S region ( e.g. , S gamma1 ) by end-joining . In normal cells , many CSR junctions are mediated by classical nonhomologous end-joining ( C-NHEJ ) , which employs the Ku70/80 complex for DSB recognition and XRCC4/DNA ligase 4 for ligation . Alternative end-joining ( A-EJ ) mediates CSR , at reduced levels , in the absence of C-NHEJ , even in combined absence of Ku70 and ligase 4 , demonstrating an A-EJ pathway totally distinct from C-NHEJ . Multiple DSBs are introduced into S mu during CSR , with some being rejoined or joined to each other to generate internal switch deletions ( ISDs ) . In addition , S-region DSBs can be joined to other chromosomes to generate translocations , the level of which is increased by absence of a single C-NHEJ component ( e.g. , XRCC4 ) . We asked whether ISD and S-region translocations occur in the complete absence of C-NHEJ ( e.g. , in Ku70/ligase 4 double-deficient B cells ) . We found , unexpectedly , that B-cell activation for CSR generates substantial ISD in both S mu and S gamma1 and that ISD in both is greatly increased by the absence of C-NHEJ . IgH chromosomal translocations to the c-myc oncogene also are augmented in the combined absence of Ku70 and ligase 4 .

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

Here , we investigate the molecular mechanism underlying the extreme response of a head and neck tumor case ( SKX ) to standard radiotherapy . METHODS Immunofluorescence ( IF ) was used for the assessment of DSB repair , Western blot and real-time PCR for protein and mRNA expression , respectively . RESULTS SKX cells exhibited a pronounced radiosensitivity associated with numerous residual γ-H2AX foci after IR . This was not associated with lacking canonical repair proteins . SKX cells did not express any ATM protein . Accordingly , immunoblotting revealed no ATM kinase activity toward substrates such as p-SMC1 , p-CHK2 and p-KAP1 . Sequencing of all 66 exons of ATM showed no mutation . ATM mRNA level was moderately reduced , which could be reverted by 5'-Aza-C treatment but without restoring protein levels . Importantly , we demonstrated a post-transcriptional regulation in SKX cells via 6-fold enhanced levels of miR-421 , which targets the 3'-UTR of ATM mRNA . Transfection of SKX cells with either anti-miR-421 inhibitor or a microRNA-insensitive ATM vector recovered ATM expression and abrogated the hyper-radiosensitivity . CONCLUSION This is the first report describing microRNA-mediated down-regulation of ATM leading to clinically manifest tumor radiosensitivity .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Carbon monoxide ( CO ) , one of the products of the cytoprotective molecule heme oxygenase-1 ( HO-1 ) in cancer cells , has been implicated in carcinogenesis and therapeutic resistance . However , the functional contributions of CO and HO-1 to these processes are poorly defined . In human prostate cancers , we found that HO-1 was nuclear localized in malignant cells , with low enzymatic activity in moderately differentiated tumors correlating with relatively worse clinical outcomes . Exposure to CO sensitized prostate cancer cells but not normal cells to chemotherapy , with growth arrest and apoptosis induced in vivo in part through mitotic catastrophe . CO targeted mitochondria activity in cancer cells as evidenced by higher oxygen consumption , free radical generation , and mitochondrial collapse . Collectively , our findings indicated that CO transiently induces an anti-Warburg effect by rapidly fueling cancer cell bioenergetics , ultimately resulting in metabolic exhaustion .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;cellular energetics" } ]

A high affinity laminin receptor in tumor cells is thought to be blocked by the carboxyl-terminal YIGSR , and conformational energy calculations suggest that the glycine in YIGSR allows an important conformational bend . We replaced the YIGSR glycine residue in peptide 11 with either D-alanine or L-alanine to allow or disfavor the proposed glycine bend . We found the Gly7-->D-Ala7 analog to be equal to peptide 11 in inhibiting tumor cell invasion of basement membrane matrix . The Gly7-->L-Ala7 analog was much less capable of invasion inhibition . Two-dimensional 1H-1H NMR was used to study the solution conformations of the peptide 11 analogs . NOESY experiments revealed close NH-NH contacts in peptide 11 and the D-Ala7 analog , but not in the L-Ala7 analog . Molecular dynamics generated low energy structures with excellent NOE agreement for peptide 11 and its analogs . Both peptide 11 and the D-Ala7 analog , but not the less active L-Ala7 analog , were predicted to have similar bends around Gly7 or D-Ala7 . These results suggest that a bend in the YIGSR region of peptide 11 may be important for the binding of laminin to its metastasis-associated receptor .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

Here we report the establishment of a functional hepatocyte cell line , SDRL-1 , from the liver of young male spontaneous dwarf rats ( SDR ) , with isolated GH deficiency . This line has been maintained in Dulbecco's Modified Eagle Medium ( DMEM)/F12 medium supplemented with 10% fetal bovine serum ( FBS ) with retention of a near diploid karyotype for extended periods of time . When grown as a monolayer sheet , it displayed a pavement-like appearance and contact inhibition . These cells have a poorly developed rough endoplasmic reticulum ( r-ER ) , few mitochondria and glycogen granules , and produce a small amount of albumin and α-fetoprotein , that is enhanced when grown on a collagen gel sponge . Human recombinant GH stimulated JAK2 and STAT5b tyrosine phosphorylation and IGF-I production in a concentration-dependent manner . When the cells were cultured with GH-supplemented medium , the number of mitochondria and glycogen granules increased together with the r-ER and Golgi apparatus . A number of microvilli were observed on the surface of the cultured cells , further suggesting that this cell line is composed of normally functioning hepatocytes . In summary , we established a novel hepatocyte cell line ( SDRL-1 ) , that appears to display normal function , which we propose can serve as a good in vitro model for studying GH-target organ interactions .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

The prototype anti-estrogen binding site/intracellular histamine receptor ligand , N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine HCl , inhibits normal cell proliferation in vitro but stimulates tumor growth in vivo . Because of their structural similarity to N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine HCl , we carried out studies to determine whether amitriptyline and fluoxetine stimulate tumor growth and/or development in rodents at concentrations relevant to the treatment of human depression ( equivalent human dose range , approximately 100-150 mg/day for amitriptyline and approximately 20-80 mg/day for fluoxetine ) . All experiments were performed blinded . In studies of growth stimulation of transplantable syngeneic tumors , groups of mice were inoculated s.c. with C-3 fibrosarcoma cells or given i.v. or s.c. injections of B16f10 melanoma cells , followed 24 h later by daily i.p. injections of saline , amitriptyline , or fluoxetine . Tumor latency ( fibrosarcoma ) , aggregate tumor weight ( s.c. injected melanoma ) , or time to death from pulmonary metastasis ( i.v. injected melanoma ) was determined ; drug-induced stimulation of DNA synthesis in C-3 fibrosarcoma cells in vitro was correlated with tumor growth acceleration in vivo . In a mammary carcinogenesis model , the effects of chronic saline , amitriptyline , or fluoxetine administration on the rate and frequency of development of mammary tumors in rats fed dimethylbenzanthracene ( DMBA ) were compared . Eight of 20 amitriptyline- or fluoxetine-treated mice developed fibrosarcoma tumors by day 5 , as compared to none of 20 saline controls ( P less than 0.002 ) . Similarly , 20 of 21 DMBA-treated rats receiving the antidepressant drugs developed 33 mammary tumors by week 15 as compared to 5 tumors in 4 of 7 DMBA-treated rats receiving saline ( P less than 0.001 ) . For both models , tumor latency decreased 30-40% and , in the DMBA model , tumor frequency increased greater than 2-fold in the antidepressant-treated rats as compared to controls . Stimulation of fibrosarcoma growth in vivo correlated with a corresponding bell-shaped drug-induced increase in DNA synthesis in vitro . While the median time to death from pulmonary metastases did not differ among groups given i.v. injections of melanoma cells , a significant ( P less than 0.01 ) stimulation of growth of s.c. injected melanoma was observed in mice receiving the antidepressants.(ABSTRACT TRUNCATED AT 400 WORDS )\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;activating invasion and metastasis" } ]

In this study we describe the effect of PDA-66 , a newly synthesised indolylmaleimide , showing a strong dose dependent anti-proliferative effect on immortalised human progenitor and cancer cells . We demonstrated a highly depolymerizing effect on in vitro tubulin assembly and conclude that PDA-66 acts as microtubule destabilising agent . In addition we found that PDA-66 induces mitotic arrest of cells in the G(2)/M phase of the cell cycle . Subsequently cells undergo apoptosis , indicating the major mechanism of the anti-proliferative effect . To prove a potential anti-cancer activity of PDA-66 we examined the effect of PDA-66 on human SH-SY5Y neuroblastoma and A-459 lung cancer cells , showing a significant reduction in cancer cell proliferation in a dose dependent manner .

The selection was based on their ability to form confluent monolayers on porous supports and to maintain receptor-mediated signal transduction and ion transport , characteristic of the proximal tubule . The isolation method consisted of several steps : ( 1 ) superficial cortical proximal tubule segments were microdissected and cultured on a matrix-coated porous support until cells formed a confluent monolayer ; ( 2 ) primary cultures showing hormone-regulated ion transport typical for the proximal tubule were selected and co-cultured with irradiated fibroblasts ; and ( 3 ) the epithelial cells surviving after several passages were expanded and passaged on porous substrates . Most of the cell lines developed in this manner were obtained by co-culture with irradiated fibroblasts producing a recombinant retrovirus encoding SV40 large T antigen and G418 resistance . However , SV40 T antigen expression was not essential for immortalization , since neither T antigen nor G418 resistance was detected in the isolated cell lines and co-culture with non-producing 3T3 cells gave similar results . One cell line ( vEPT ) has been characterized in some detail with respect to morphological , biochemical , and ion transport properties . This line forms confluent monolayers with apical microvilli , tight junctions , and convolutions of the basolateral plasma membrane . Once confluent , monolayers maintain conductances of 25 to 32 mS/cm2 for several weeks in culture and possess phlorizin-sensitive short-circuit current ( Isc ) in glucose containing media , indicative of apical Na(+)-glucose co-transport. vEPT cells also retain receptor and signaling mechanisms for angiotensin II ( Ang II ) . Apical and basal Ang II and 5,6-epoxy-eicosatrienoic acid ( 5,6-EET ) modulate the Isc in a manner similar to primary cultures . The cell lines share with primary cultures expression of the cytokeratins K8 , K10/K11 , and K19 ( \"nomenclature \" [ 21] ) . They also retain several receptor and signal transduction mechanisms .

Cancer hyperthermia therapy results in shrinkage of tumors by various mechanisms , including induction of adaptive immune response . However , the physiological meaning of systemic fever and mechanisms of tumor shrinkage by hyperthermia have not been completely understood . In this study , we investigated how heat shock influences the adaptive immune system . We established a cytotoxic T lymphocyte ( CTL ) clone ( #IM29 ) specific for survivin , one of the tumor-associated antigens ( TAAs ) , from survivin peptide-immunized cancer patients ' peripheral blood , and the CTL activities were investigated in several temperature conditions ( 37-41�C ) . Cytotoxicity and IFN-γ secretion of CTL were greatest under 39�C condition , whereas they were minimum under 41�C . To address the molecular mechanisms of this phenomenon , we investigated the apoptosis status of CTLs , expression of CD3 , CD8 , and TCRαβ by flow cytometry , and expression of perforin , granzyme B , and Fas ligand by western blot analysis . The expression of perforin and granzyme B were upregulated under temperature conditions of 39 and 41�C . On the other hand , CTL cell death was induced under 41�C condition with highest Caspase-3 activity . Therefore , the greatest cytotoxicity activity at 39�C might depend on upregulation of cytotoxic granule proteins including perforin and granzyme B. These results suggest that heat shock enhances effector phase of the adaptive immune system and promotes eradication of microbe and tumor cells .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

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 .

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

However , whether or not OP-B has any potential antitumor activity has not been reported . Here , we show that the non-small cell lung cancer ( NSCLC ) cell lines NCI-H157 and NCI-H460 treated with OP-B grow more slowly and accumulate vacuoles in their cytoplasm compared to untreated control cells . Flow cytometric analysis showed that the cells were arrested in G0/G1 phase . Nuclear morphology , Annexin-V/PI staining , and expression of cleaved caspase-3 all confirm that OP-B does not induce apoptosis . Instead , based on results from both transmission electron microscopy ( TEM ) and the expression of microtubule-associated protein 1 light chain 3-II ( LC3-II ) , we determined that OP-B treatment induced autophagy in both cell lines . Next , we examined the PI3K/Akt/mTOR signaling pathway and found that OP-B inhibited phosphorylation of Akt(Ser473 , Thr308 ) in NCI-H157 cells and also inhibited several key components of the pathway in NCI-H460 cells , such as p-Akt(Ser473 , Thr308 ) , p-p70S6K ( Thr389 ) . Additionally , insulin-mediated activation of the PI3K/Akt/mTOR pathway provides evidence that activation of this pathway may correlate with induction of autophagy in H460 cells . Therefore , OP-B is a prospective inhibitor of PI3K/Akt and may be used as an alternative compound to treat NSCLC .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

In addition to being terminally arrested in the cell cycle , senescent fibroblasts express genes that are normally induced upon wounding , including genes that remodel the extracellular matrix . We have identified the novel zinc finger protein APA-1 , whose expression increased in senescent human fibroblasts independent of telomere shortening . Extended passage , telomerase-immortalized fibroblasts had increased levels of APA-1 as well as the cyclin-dependent kinase inhibitor p16 . In fibroblasts , APA-1 was modified by the ubiquitin-like protein SUMO-1 , which increased APA-1 half-life , possibly by blocking ubiquitin-mediated degradation . Overexpression of APA-1 did not cause cell cycle arrest ; but , it induced transcription of the extracellular matrix-remodeling genes MMP1 and PAI2 , which are associated with fibroblast senescence . MMP1 and PAI2 transcript levels also increased in telomerase-immortalized fibroblasts that had high levels of APA-1 , demonstrating that the matrix-remodeling phenotype of senescent fibroblasts was not induced by telomere attrition alone . APA-1 was able to transactivate and bind to the MMP1 promoter , suggesting that APA-1 is a transcription factor that regulates expression of matrix-remodeling genes during fibroblast senescence .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;sustaining proliferative signaling" } ]

The disease follows autosomal dominant inheritance pattern with high penetrance ( 85% ) and younger age of onset when compared to patients with sporadic tumours . HNPCC is associated with germ-line mutations in the DNA mismatch repair ( MMR ) genes namely MLH1 , MSH2 , MSH6 , and PMS2 . The present study was aimed at analyzing mismatch repair gene(s) in an extended Indian family satisfying the Amsterdam criteria , and extending the analysis to general population to estimate frequency of the mutations/polymorphisms observed . METHODS A total 12 members of the HNPCC family were studied for genetic investigation . Ethnically matched 250 normal individuals were also included as controls to study the observed mutations/polymorphisms at population level . RESULTS The analysis resulted in identification of a 1975C>T mutation in exon 17 , resulting in substitution of arginine residue with stop codon at codon 659. 655A>G substitution was also observed , resulting in replacement of isoleucine with valine at codon 219 . Similar analysis on 250 ethnically matched control subjects revealed complete absence of R659X mutation , while I219V variant was found in 9.8 per cent of the controls . INTERPRETATION &amp ; CONCLUSION R659X mutation correlates with disease phenotype , and 655A>G locus is highly polymorphic . Our study suggested that R659X substitution was prime cause for the disease phenotype in this family . I219V substitution is a polymorphism having no association with the disease onset or segregation . The family members harbouring this mutation were advised to be under regular medical surveillance .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

ECM detachment induces metabolic stress and programmed cell death via anoikis . ECM-detached mammary epithelial cells are able to rapidly activate autophagy allowing for survival and an opportunity for re-attachment . However , the mechanisms controlling detachment-induced autophagy remain unclear . Here we uncover that the kinase PERK rapidly promotes autophagy in ECM-detached cells by activating AMP-activated protein kinase ( AMPK ) , resulting in downstream inhibition of mTORC1-p70(S6K) signaling . LKB1 and TSC2 , but not TSC1 , are required for PERK-mediated inhibition of mammalian target of rapamycinin MCF10A cells and mouse embryo fibroblast cells . Importantly , this pathway shows fast kinetics , is transcription-independent and is exclusively activated during ECM detachment , but not by canonical endoplasmic reticulum stressors . Moreover , enforced PERK or AMPK activation upregulates autophagy and causes luminal filling during acinar morphogenesis by perpetuating a population of surviving autophagic luminal cells that resist anoikis . Hence , we identify a novel pathway in which suspension-activated PERK promotes the activation of LKB1 , AMPK and TSC2 , leading to the rapid induction of detachment-induced autophagy . We propose that increased autophagy , secondary to persistent PERK and LKB1-AMPK signaling , can robustly protect cells from anoikis and promote luminal filling during early carcinoma progression.Oncogene advance online publication , 19 November 2012 ; doi:10.1038/onc.2012.512 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

The Ras oncogene is frequently activated or mutated in human cancers , but Ras activation is insufficient to transform primary cells . Ina search for cooperating oncogenes , we identify the lysine demethylase JMJD2A/KDM4A . We show that JMJD2A functions as a negative regulator of Ras-induced senescence and collaborates with oncogenic Ras to promote cellular transformation by negatively regulating the p53 pathway . We find CHD5 , a known tumor suppressor regulating p53 activity , as a target of JMJD2A . The expression of JMJD2A inhibits Ras-mediated CHD5 induction leading to a reduced activity of the p53 pathway . In addition , we show that JMJD2A is overexpressed inmouse and human lung cancers .

Since previous reports demonstrated over-expression of PrxIII in cervical cancer , we conducted the present study to investigate the significance of PrxIII in cervical cancer development and/or progression . Cervical cancer cells were cultured from tissues derived from cervical cancer patients . After successful knockdown of PrxIII expression by small interfering RNA , we evaluated ROS level , viable cell number , and apoptosis of cervical cancer cells along with the culture time . The production of ROS was increased in cervical cancer cells as compared with normal cervical epithelia . Knockdown of PrxIII expression induced up-regulation of other Prx members including PrxI , PrxII , and PrxV . ROS level was higher in down-regulated cervical cancer cells than in controls and the difference was increasing with culture time . We also observed increased apoptosis and decreased viable cell number in down-regulated cervical cancer cells .

However , its role in cholangiocarcinoma ( CCA ) , a chemoresistant bile duct carcinoma with a poor prognosis , remains unclear . In this study we found that AIB1 protein was frequently overexpressed in human CCA specimens and CCA cell lines . Down-regulation of AIB1 induced the G2/M arrest and decreased the expression of mitosis-promoting factors including Cyclin A , Cyclin B , and Cdk1 through suppressing the Akt pathway , which resulted in inhibiting CCA cell proliferation . In addition , AIB1 enhanced the chemoresistance of CCA cells at least in part through up-regulating the expression of antiapoptotic protein Bcl-2 . AIB1 regulated the expression of Bcl-2 in CCA cells through activating the Akt pathway as well as suppressing intracellular reactive oxygen species ( ROS ) . AIB1 suppressed ROS by up-regulating antioxidants such as glutathione synthetase and glutathione peroxidase , which are targets of the NF-E2-related factor 2 ( Nrf2 ) , a critical transcription factor that regulates antioxidants , detoxification enzymes , and drug efflux proteins . AIB1 also increased the expression of another two Nrf2 targets , ABCC2 and ABCG2 , to enhance drug efflux . AIB1 served as an essential coactivator for Nrf2 activation by physically interacting with Nrf2 to enhance its transcriptional activity . Conclusion : AIB1 plays an important role in proliferation and chemoresistance of CCA through simultaneous activation of Akt and Nrf2 pathways , suggesting that AIB1 is a potential molecular target for CCA treatment .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;resisting cell death;tumor promoting inflammation" } ]

METHODS The tumor tissues of 115 patients with gastric cancer were immunohistochemically evaluated using monoclonal antibodies against NF-κB RelA . Preoperative serum levels of vascular endothelial growth factor ( VEGF ) , interleukin-6 ( IL-6 ) were assessed via enzyme-linked immuno-sorbent assay . C-reactive protein ( CRP ) and serum amyloid A ( SAA ) were measured via immunotrubidimetry . RESULTS Positive rate of NF-κB RelA was 42.6% . NF-κB RelA expression in tumor tissues was also related to serum levels of IL-6 ( P = 0.044 ) and CRP ( P = 0.010 ) . IL-6 , SAA , CRP were related to depth of invasion , VEGF and SAA were correlated with lymph node metastasis . IL-6 , VEGF , SAA and CRP were related to the stage . Univariate analysis demonstrated that immunostaining of NF-κB RelA , levels of IL-6 , VEGF , SAA were significantly related with both disease free survival and overall survival ( OS ) . Multivariate analysis verified that NF-κB RelA [ hazard ratio ( HR ) : 3.40 , P = 0.024 ] and SAA ( HR : 3.39 , P = 0.045 ) were independently associated with OS . CONCLUSION Increased expression of NF-κB RelA and high levels of serum SAA were associated with poor OS in gastric cancer patients .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

In general , it is thought that GFP is nontoxic to cells , although there are some reports on the side effect of GFP . Further , details of the molecular mechanism concerning the side effect of GFP remain unclear . Here we show that Ku80 , but not XRCC4 , plays an important role in the mechanism of the resistance to cytotoxicity induced by enhanced GFP ( EGFP ) . EGFP inhibited both cell proliferation and colony formation , and induced cell death in Ku80-deficient hamster cells , i.e. , xrs-6 cells . In addition , Ku80 attenuated EGFP-induced cytotoxicity in the xrs-6 cells . No EGFP-induced cytotoxicity was observed in the NHEJ core protein XRCC4-deficient hamster cells , i.e. , XR-1 cells . Furthermore , EGFP markedly enhanced X-ray-induced cytotoxicity in the xrs-6 cells . These results suggest that Ku80 plays a key role in the novel NHEJ-independent defense mechanism against EGFP-induced cytotoxicity . Caution should be taken in considering of the potential influence by the stress response mechanism , namely , the Ku80-dependent elimination mechanism of EGFP-induced cytotoxicity , being activated , even when using EGFP-expressing cells in which Ku80 functions normally .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Stimulatory immunoreceptors are usually composed of a ligand-binding transmembrane protein and noncovalently associated signal-transducing subunits . Here , we report that alternative splicing leads to two distinct NKG2D polypeptides that associate differentially with the DAP10 and KARAP ( also known as DAP12 ) signaling subunits . We found that differential expression of these isoforms and of signaling proteins determined whether NKG2D functioned as a costimulatory receptor in the adaptive immune system ( CD8+ T cells ) or as both a primary recognition structure and a costimulatory receptor in the innate immune system ( natural killer cells and macrophages ) . This strategy suggests a rationale for the multisubunit structure of stimulatory immunoreceptors .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

Analyses were performed using array CGH ( Agilent platform ) and PIK3CA ( exon 10 and 21 ) and AKT1 mutations were explored by standard Sanger sequencing . One hundred and eight patients were included . Good quality CGH was obtained in 79% cases and was better for frozen samples . Genomic alterations were identified in 50% of patients including 11 PIK3CA and 8 AKT1 mutations . Eighteen treatments ( 17 patients ) were administered according to their molecular profile with evidence of activity in nine . Reasons for not providing a genomic-driven treatment included absence of progressive disease ( 38% ) , investigator's choice ( 9% ) , rapid PD ( 19% ) , and no drug access ( 21% ) .

In the present study , we examine the function and regulation of GREB1 in breast cancer , with the goal to develop GREB1 as a biomarker in breast cancer with de novo and acquired tamoxifen resistance . METHODS We overexpressed GREB1 using adenovirus containing the full length GREB1 cDNA ( Ad-GREB1 ) in breast cancer cell lines . The soft agar assay was used as a measure of anchorage independent growth . The effects of GREB1 on cell proliferation in MCF-7 cells transduced with Ad-GREB1 were also measured by the me olic activity using AlamarBlue assay . We tested whether there was interaction between STAT3 and ER , which could repress GREB1 expression by immunoprecipitation assay . The effects of IL-6/JAK/STAT3 cascade activation on estrogen-induced GREB1 promoter activity were determined by luciferase assay and those on gene expression were measured by real time reverse transcription polymerase chain reaction ( qRT-PCR ) . RESULTS We found that the ability of breast cancer cells to grow in soft agar is enhanced following GREB1 transfection . In MCF-7 cells transduced with Ad-GREB1 or transfected with siRNA GREB1 , the metabolic activity was increased or completely abolished , suggesting that GREB1 may function as a growth promoter in breast cancer . E2 treatment increased GREB1 promoter luciferase activity . IL-6 inhibited E2-induced GREB1 transcription activity and GREB1 mRNA expression . Constitutively expressing active STAT3 construct ( STAT3-C ) dramatically decreased GREB1 transcription . CONCLUSIONS These data indicate that overexpression of GREB1 promotes cell proliferation and increases the clonogenic ability in breast cancer cells . Moreover , Il6/STAT3 modulates estrogen-induced GREB1 transcriptional activity in breast cancer cells .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Type 1 ( T1 ) T-cell cytokines play a major role in this antileukemic immune effect . Studies in cancer patients have demonstrated a decreased T1 cytokine production , measured by enzyme-linked immunosorbent assay ( ELISA ) , in cultures of peripheral blood mononuclear cells . This observation of malignancy-related suppressed T1 cytokines also occurs in untreated chronic-phase ( CP ) CML , raising the question of the influence of different CML treatment regimens on this immunosuppression . Intracellular flow cytometry ( ICF ) has facilitated the evaluation of cytokines on a single-cell level . This study analyzed T1 ( interferon-gamma ) cytokine production in purified peripheral blood T cells by ICF , comparing different therapy approaches for CML . Twenty-one newly diagnosed CP CML patients were compared with 24 patients treated with interferon-alpha ( IFN-alpha ) and to 30 allogeneic bone marrow transplant ( BMT ) recipients ( BCR-ABL negative by reverse-transcriptase polymerase chain reaction , and free of , or having only limited graft-versus-host disease at the time of study ) . Thirty-seven healthy controls were included . Our results showed a significantly decreased T-cell IFN-gamma synthesis in CP CML patients in relation to healthy controls ( P = 0.0007 ) . Treatment with IFN-alpha resulted in a shift from immunosuppression--documented for the group of untreated patients--to immunopotentiation , with an increase of T-cell IFN-gamma production ( P = 0.0266 ) . Notably , BMT enhanced IFN-gamma production of T cells to a level not only exceeding untreated patients ( P &lt ; 0.0001 ) but also healthy volunteers ( P &lt ; 0.0001 ) . The observation of T1 cytokine up-regulation with IFN-alpha therapy indicates that enhanced T-cell function may be achievable in patients with CML , even in the absence of an allo-response .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

Downregulation of Par3 cooperated with ErbB2 to induce cell invasion and metastasis in vivo . Interestingly , the metastatic behaviour was not associated with an overt mesenchymal phenotype . However , loss of Par3 inhibited E-cadherin junction stability , disrupted membrane and actin dynamics at cell-cell junctions and decreased cell-cell cohesion in a manner dependent on the Tiam1/Rac-GTP pathway . Inhibition of this pathway restored E-cadherin junction stability and blocked invasive behaviour of cells lacking Par3 , suggesting that loss of Par3 promotes metastatic behaviour of ErbB2-induced tumour epithelial cells by decreasing cell-cell cohesion .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

We hypothesize that , in the tumor microenvironment , tumor cells and resident tissue cells ( e.g. , fibroblasts ) also produce cytokines that may regulate the local immune response to tumors . Initially , homogenates of eight head and neck squamous cell carcinomas ( HNSCC ) were assayed for the presence of interleukin-1 ( IL-1 ) , interleukin-4 ( IL-4 ) , interleukin-6 ( IL-6 ) , and granulocyte-macrophage colony-stimulating factor ( GM-CSF ) to establish the presence of these cytokines in the tumors in vivo . We detected IL-1 in all tumor homogenates and IL-4 , IL-6 , and GM-CSF in some homogenates . To assess the ability of HNSCC to produce these cytokines , supernatants of short-term primary cultures of HNSCC were assayed for the same cytokines . No IL-1 was detected , although baseline levels of IL-4 , IL-6 , and GM-CSF were present . However , the stimulation of primary tumor cultures with exogenous IL-1 induced or significantly enhanced production of IL-4 ( p &lt ; 0.01 ) , IL-6 ( p &lt ; 0.001 ) , and GM-CSF ( p &lt ; 0.02 ) . These results support our hypothesis that HNSCC secrete cytokines that may influence the response of local immune cells .

Little is known about the tumor-suppressive function of RASSF1A in breast tissue and whether its inactivation is mechanistically involved in the initiation and progression of breast tumors . Here , we show that RASSF1A inhibits breast cancer growth in vivo , and suppresses estrogen receptor ( ERα ) expression and function . Reconstitution of RASSF1A in MCF7 cells led to decreased ERα levels and reduced sensitivity to estrogen ( E2 ) . Concomitantly , we observed decreased expression of Id1 as well as the E2-responsive genes Bcl-2 and c-Myc that cooperatively contribute to the immortalization and transformation of breast epithelial cells . This downregulation was associated with induction of cell-cycle arrest and senescence that constitute early barriers to cancer initiation and progression . Knockdown of ERα showed that downregulation of ERα suffices to increase senescence and inhibit expression of Bcl-2 , c-Myc and Id1 . However , enforced expression of ERα only partially rescued RASSF1A-mediated growth inhibition and senescence , suggesting that suppression of ERα expression and activity is not the only mechanism by which RASSF1A inhibits growth and survival of breast cancer cells . Ectopic expression of Bcl-2 , c-Myc and Id1 had little or no effect on RASSF1A-mediated growth arrest , indicating that RASSF1A acts dominantly over these oncogenes . Mechanistically , RASSF1A was found to suppress ERα expression through Akt1 . It also transiently inhibited ERα-induced Ras-MAPK activity after exposure of cells to E2 . Together , our data show that RASSF1A acts as a tumor suppressor in ERα+ mammary epithelial cells , in part through inhibiting ERα expression and activity . These findings suggest that RASSF1A has a key role in suppressing the transformation of human breast epithelial cells and ERα+ breast cancer initiation .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;enabling replicative immortality" } ]

We compared their frequencies in groups of colon , head and neck , and breast cancer patients , and 2 healthy control groups : ( 1 ) matched healthy Polish individuals and ( 2 ) a NCBI database control group . Highly significant differences in the distribution of genotypes of the APE1 , XRCC1 and CCND1 genes were found between colon cancer patients and healthy individuals . The 148Asp APE1 allele and the 399Gln XRCC1 allele apparently increased the risk of colon cancer ( OR = 1.9-2.3 and OR = 1.5-2.1 , respectively ) .

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 .

The aim of this study was to investigate whether the combined use of epirubicin and progesterone has a synergistic effect on cell proliferation and apoptosis in HepG2 cells . METHODOLOGY Different concentrations of epirubicin ( 0.1 microg/ml , 0.25 microg/ml and 0.5microg/ml ) or progesterone ( 12.5 microM , 25 microM and 50 microM ) were added to HepG2 cells either alone or in combinations consisting of different concentrations of the two . Their effects on HepG2 cells were studied by ( 1 ) XTT assay for analysis of cell proliferation , ( 2 ) 3H-Thymidine incorporation for DNA synthesis , ( 3 ) annexin V-FITC/ propidium iodide ( PI ) flowcytometery for cell apoptosis , ( 4 ) flowcytometry for cell cycle distributions , and ( 5 ) reverse transcription-polymerase chain reaction for expression of cell cycle modulator , cyclin D1 . RESULTS 50 microM progesterone increased both the cytotoxic and apoptotic effects of 0.1 microg/ml epirubicin on HepG2 cells at 48 hr culture due to 50 microM progesterone accumulated cells in S phase of the cell cycle and subsequently reduced cyclin D1 expression . These effects on HepG2 cells induced by this combination were comparable to those induced by 0.5 microg/ml epirubicin alone . CONCLUSIONS In vitro , progesterone can increase the cytotoxicity and apoptosis induced by epirubicin on HepG2 cells .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling" } ]

Like other cyclin-dependent kinases ( CDKs ) , assembly with cyclins is the most critical step for activation of CDK4/6 . As previously reported elsewhere , we observed that the level of cyclinD1-CDK4 complex and its associated kinase activity were significantly low in asynchronously proliferating mouse embryo fibroblasts lacking both p21(Cip1) and p27(Kip1) ( p21/p27-null MEFs ) . These evidences imply that p21(Cip1) and p27(Kip1) CDK inhibitors are ' essential activators ' of cyclin D-kinases . We , however , discovered here that both the assembly and activation of cyclin D1-CDK4 complex occur when quiescent p21/p27-null MEFs were stimulated to re-enter the cell cycle . This mitogen-induced cyclin D1-kinase activity was blocked by overexpression of p16(INK4a) and resulted in the inhibition of S phase entry in p21/p27-null MEFs . Furthermore , ectopic expression of p34(SEI-1) , a mitogen-induced CDK4 binding protein , increased the levels of active cyclinD1-CDK4 complex in asynchronously proliferating p21/p27-null MEFs . Together , our results suggest that there are several independent ways to stimulate the assembly of cyclin D1-CDK4 kinases . Although p21(Cip1) and p27(Kip1) play a role in this process , our results demonstrate that additional mechanisms must occur in G0 to S phase transition .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

Antidepressant desipramine ( DMI ) is clinically prescribed in the auxiliary treatment of cancer patients . Increasing evidences suggest that DMI has a broad spectrum of target-off biological effects , such as anticancer properties . Our previous study revealed that DMI at the clinical relevant concentrations could induce CHOP-dependent apoptotic death in C6 glioma cells . In this study , we further explored the pro-autophagic effect of DMI in C6 glioma cells and its underlying mechanism . Treatment with DMI could induce autophagic cell death characterized by the formation of autophagosome and the elevated level of autophagic protein Beclin-1 and cellular redistribution of marker LC3 . Meanwhile , DMI inhibited the activation of PI3K-AKT-mTOR pathway which is considered as a negative regulator of autophagy . Furthermore , DMI activated PERK-eIF2α and ATF6 of endoplasmic reticulum ( ER ) stress pathway , while knockdown of PERK with the PERK-specific short interfering RNA ( siRNA ) could obviously attenuate the autophagy . The results strongly suggested that DMI could induce autophagy through the PERK-ER stress pathway in C6 glioma cells .

Transduction of human endothelial cells with PEX virus suppressed endothelial invasion and formation of capillary-like structures without affecting chemotaxis in vitro . Lentiviral delivery of PEX blocked basic fibroblast growth factor-induced matrix metalloproteinase 2 activation and angiogenesis on chicken chorioallantoic membranes . PEX expression also inhibited tumor-induced angiogenesis and tumor growth in a nude mouse model .

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

The plant kingdom is a relatively underexploited cache of novel drugs , and crude extracts of plants are known for their synergistic activity . The present study assessed the anti-proliferative activity of the medicinal plant Centrosema pubescens Benth . Centrosema pubescens dichloromethane extract ( CPDE ) inhibited the proliferation of HL-60 ( promyelocytic acute leukaemia ) cells with an IC₅₀ value of 5 μg/ml . Further studies also showed that CPDE induces growth arrest at the G1 phase and specifically down-regulates the expressions of cyclin E and CDK2 and up-regulates p27(CKI) levels . These events apparently lead to the induction of apoptosis , which was demonstrated qualitatively by a DNA fragmentation assay and propidium iodide staining . Quantitative assessment of the effective arrest of the cell cycle and of apoptosis was confirmed by flow cytometry . CPDE exhibited negligible cytotoxicity even at the highest dose tested ( 100 μg/ml ) in both normal peripheral blood mononuclear cells and in an in vitro model ( HL-60 ) . Our results strongly suggest that CPDE arrests the cell cycle at the G1 phase and triggers apoptosis by caspase activation .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;resisting cell death" } ]

We recently showed that DMSO induces a G(1) phase arrest in Chinese hamster ovary ( CHO ) cells , by restoring contact inhibition and preventing high density-dependent apoptosis . CHO cells are frequently used in cell biology and mutagenesis studies due to their good growth capacity and ease of manipulation but are very difficult to synchronize by serum starvation since they detach from monolayers when they reach confluence . In this study we investigated the possibility of using DMSO to reversibly synchronize CHO cells in the G(1) phase of the cell cycle and analysed whether toxic effects follow the arrest using growth curve , sister chromatid exchange and micronuclei assays . We carried out a kinetic analysis of the arrest by DMSO and re-entry into the cell cycle after drug release by cytofluorimetric analysis of DNA content and bromodeoxyuridine incorporation . We show that CHO cells are efficiently and reversibly arrested in G(1) by DMSO in concentrations ranging between 1 and 2% . In our experiments , >90% of cells grown for 96 h in presence of the drug were arrested in G(1) and synchronously re-entered S phase approximately 8-12 h after release . Furthermore , expression levels of p27 were down-regulated during G(1) progression and cyclin D3 and E expression patterns were similar to those observed after serum starvation . No detectable cytotoxicity or genetic damage were induced in G(1) released cells as revealed by the tests employed . Our results show that DMSO is a very powerful inducer of G(1) synchronization in CHO cells without detectable cytotoxic or genetic effects in cell populations released from G(1) arrest . DMSO synchronization represents a model system in which to analyse protein activities regulating G(1) progression and investigate the response of G(1) cells to mutagen treatments .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors;genomic instability and mutation" } ]

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

Frequent cytogenetic abnormalities that occur in HCC suggest that tumor-modifying genes ( oncogenes or tumor suppressors ) may be driving selection for amplification or deletion of these particular genetic regions . In many cases , however , the gene(s) that drive the selection are unknown . Although techniques such as comparative genomic hybridization ( CGH ) have traditionally been used to identify cytogenetic aberrations , it might also be possible to identify them indirectly from gene-expression studies . A technique we have called comparative genomic microarray analysis ( CGMA ) predicts regions of cytogenetic change by searching for regional gene-expression biases . CGMA was applied to HCC gene-expression profiles to identify regions of frequent cytogenetic change and to identify genes whose expression is misregulated within these regions . RESULTS Using CGMA , 104 HCC gene-expression microarray profiles were analyzed . CGMA identified 13 regions of frequent cytogenetic change in the HCC samples . Ten of these regions have been detected in previous CGH studies ( +lq , -4q , +6p , -8p , +8q , -13q , -16q , -17p , +17q , +20q ) . CGMA identified three additional regions that have not been previously identified by CGH ( +5q , +12q , +19p ) . Genes located in regions of frequent cytogenetic change were examined for changed expression in the HCC samples . CONCLUSIONS Our results suggest that CGMA predictions using gene-expression microarray datasets are a practical alternative to CGH profiling . In addition , CGMA might be useful for identifying candidate genes within cytogenetically abnormal regions .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

An appreciation of associated pathology with IPC may be critical in surgical decision-making . METHODS The medical records of all patients with IPC treated between 1985 and 2001 were retrospectively reviewed . Three patient groups were identified according to the pathologic features of the primary tumor : IPC alone , IPC with associated ductal carcinoma in situ ( DCIS ) , and IPC with associated invasion with or without DCIS . Types of treatment and outcomes were compared between groups . RESULTS Forty patients were treated for IPC during the study period . Fourteen had pure IPC , 13 had IPC with DCIS , and 13 had IPC with invasion . The incidence of recurrence and the likelihood of dying of IPC did not differ between the three groups regardless of the type of surgery ( mastectomy or segmental mastectomy ) performed and whether radiation therapy was administered . The disease-specific survival rate was 100% . CONCLUSIONS When IPC is identified , it is frequently associated with DCIS and or invasion . Standard therapy should be based on associated pathology . The role of radiation therapy in pure IPC remains to be determined .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

We examined the association between candidate disease-susceptibility polymorphisms in the single nucleotide polymorphism ( SNPs ) like TLR2 ( -196 to-174del ) , TLR3 ( C1377T ) , TLR4 ( Thr399Ile ) and TLR9 ( G2848A ) genes in patients with bladder cancer in a North Indian population . METHODS : SNPs were comprised of TLR2 ( -196 to -174 Del ) , TLR3(C1377T) , TLR4 ( Thr399Ile ) and TLR9 ( G2848A ) genes . Allelic and genotypic frequencies of these TLRs SNP from histopathologically confirmed patients of bladder cancer ( n=200 ) and unrelated healthy controls of similar ethnicity ( n=200 ) were genotyped by polymerase chain reaction restriction fragment length polymorphism ( PCR-RFLP ) analysis . RESULTS : In TLR2 I/D gene polymorphism , the combination of ID+DD showed a significant 3-fold increased risk ( p=0.001 ) . TLR2 with heterozygous genotype ID showed a 3-fold risk and combination of heterozygous and variant genotype ( ID+DD ) also showed a 5-fold risk with tumor stage/grade of patients with bladder cancer . The other genotypes of TLR3 , 4 and 9 did not exhibit any significant association with bladder cancer risk . CONCLUSIONS : Our results suggested the involvement of TLR2 ( -196 to-174 del ) in bladder cancer susceptibility ; however , TLR3 , 4 and 9 genes were not associated with risk of bladder cancer , implicating that polymorphisms in these tested TLRs genes are not likely to be associated with increased risk for developing bladder cancer . Functional studies in ethnically diverse populations may provide a more comprehensive involvement of innate immunity in identifying the disease-associated variants for the etiology of bladder cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

Halofuginone is a plant alkaloid derivative that blocks TGF-β signaling with antiangiogenic and antiproliferative properties . Here , we show for the first time that halofuginone therapy decreases development and progression of bone metastasis caused by melanoma cells through the inhibition of TGF-β signaling . Halofuginone treatment of human melanoma cells inhibited cell proliferation , phosphorylation of SMAD proteins in response to TGF-β , and TGF-β-induced SMAD-driven transcription . In addition , halofuginone reduced expression of TGF-β target genes that enhance bone metastases , including PTHrP , CTGF , CXCR4 , and IL11 . Also , cell apoptosis was increased in response to halofuginone . In nude mice inoculated with 1205Lu melanoma cells , a preventive protocol with halofuginone inhibited bone metastasis . The beneficial effects of halofuginone treatment were comparable with those observed with other anti-TGF-β strategies , including systemic administration of SD208 , a small-molecule inhibitor of TGF-β receptor I kinase , or forced overexpression of Smad7 , a negative regulator of TGF-β signaling . Furthermore , mice with established bone metastases treated with halofuginone had significantly less osteolysis than mice receiving placebo assessed by radiography . Thus , halofuginone is also effective in reducing the progression of melanoma bone metastases .

Many growth factors are involved in the development of the tumor-associated vasculature , and from these , endocrine gland-derived vascular endothelial growth factor ( EG-VEGF ) seems to play a crucial role . EG-VEGF is the first organ-specific angiogenic factor and its effects are restricted to the endothelial cells of the endocrine glands . Although EG-VEGF was detected in both normal and neoplastic ovaries , its clinical significance remains controversial . In the present study , we analyzed 30 patients with epithelial ovarian cancer , and the immunohistochemical expression of EG-VEGF was compared with the conventional clinico-pathological parameters of prognosis . Neoplastic cells of the ovarian carcinoma expressed EG-VEGF in 73.33% of the cases , as a cytoplasmic granular product of reaction . We found a strong correlation between the expression of EG-VEGF at protein level and tumor stage , grade , and microscopic type . The expression of EG-VEGF was found in patients with stage III and IV , but not in stage II . The majority of serous adenocarcinoma , half of the cases with clear cell carcinoma and two cases with endometrioid carcinoma showed definite expression in tumor cells . No positive reaction was found in the cases with mucinous carcinoma . Our results showed that EG-VEGF expression is an indicator not only of the advanced stage , but also of ovarian cancer progression . Based on these data , we concluded that EG-VEGF expression in tumor cells of the epithelial ovarian cancer is a good marker of unfavorable prognosis and could be an attractive therapeutic target in patients with advanced-stage tumors , refractory conventional chemotherapy .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

A mildly raised temperature ( i.e.39�C ) was imposed on the skin surface of the implanted tumor using a thermal heating pad . Periodic heating ( 12 hours per day ) was carried out for 3 days , 7 days , 14 days , and 21 days , respectively . The tumor growth rate was found significantly decreased in comparison to the control without hyperthermia . Biological evidences associated with tumor angiogenesis and metastasis were examined using histological analyses . Accordingly , the effect of mild hyperthermia on immune cell infiltration into tumors was also investigated . It was demonstrated that a delayed tumor growth and malignancy progression was achieved by mediating tumor cell apoptosis , vascular injury , degrading metastasis potential and as well as inhibiting the immunosuppressive cell myeloid derived suppressor cells ( MDSCs ) recruitment .

Mechanisms for furan carcinogenicity were investigated in male F344 rats using the in vivo Comet and micronucleus assays , combined with analysis of histopathological and gene expression changes . In addition , formamidopyrimidine DNA glycosylase ( Fpg ) and endonuclease III ( EndoIII)-sensitive DNA damage was monitored as a measure of oxidative DNA damage . Rats were treated by gavage on four consecutive days with 2 , 4 , and 8mg/kg bw furan , doses that were tumorigenic in 2-year cancer bioassays , and with two higher doses , 12 and 16mg/kg . Rats were killed 3h after the last dose , a time established as producing maximum levels of DNA damage in livers of furan-treated rats . Liver Comet assays indicated that both DNA strand breaks and oxidized purines and pyrimidines increased in a near-linear dose-responsive fashion , with statistically significant increases detected at cancer bioassay doses . No DNA damage was detected in bone marrow , a non-target tissue for cancer , and peripheral blood micronucleus assays were negative . Histopathological evaluation of liver from furan-exposed animals produced evidence of inflammation , single-cell necrosis , apoptosis , and cell proliferation . In addition , genes related to apoptosis , cell-cycle checkpoints , and DNA-repair were expressed at a slightly lower level in the furan-treated livers . Although a mixed mode of action involving direct DNA binding cannot be ruled out , the data suggest that furan induces cancer in rat livers mainly through a secondary genotoxic mechanism involving oxidative stress , accompanied by inflammation , cell proliferation , and toxicity .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;resisting cell death;tumor promoting inflammation;evading growth suppressors" } ]

We hypothesized that zinc induces A20 in premonocytic , endothelial , and cancer cells , and A20 binds to tumor necrosis factor ( TNF)-receptor associated factor , and inhibits Iκ kinase-α ( IKK-α)/nuclear factor-κB ( NF-κB ) , resulting in downregulation of TNF-α and interleukin-1β ( IL-1β ) . METHODS To test this hypothesis , we used HL-60 , human umbilical vein endothelial cells , and SW480 cell lines under zinc-deficient and zinc-sufficient conditions in this study . We measured oxidative stress markers , inflammatory cytokines , A20 protein and mRNA , A20-FRAF-1 complex , and IKK-α/NF-κB signaling in stimulated zinc-deficient and zinc sufficient cells . We also conducted antisense A20 and siRNA studies to investigate the regulatory role of zinc in TNF-α and IL-1β via A20 . RESULTS We found that zinc increased A20 and A20-tumor necrosis factor-receptor associated factor-1 complex , decreased the IKK-α/NF-κB signaling pathway , oxidative stress markers , and inflammatory cytokines in these cells compared with zinc-deficient cells . We confirmed that zinc-induced A20 contributes to downregulation of TNF-α and IL-1β by antisense and short interfering RNA A20 studies . CONCLUSION Our studies suggest that zinc suppresses generation of NF-κB-regulated inflammatory cytokines by induction of A20 .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

In this study , we examined a role for the DNA methyltransferase DNMT3B , in particular , the truncated isoform DNMT3B7 , which is generated frequently in cancer . To investigate if aberrant DNMT3B transcripts alter DNA methylation , gene expression , and phenotypic character in neuroblastoma , we measured DNMT3B expression in primary tumors . Higher levels of DNMT3B7 were detected in differentiated ganglioneuroblastomas compared to undifferentiated neuroblastomas , suggesting that expression of DNMT3B7 may induce a less aggressive clinical phenotype . To test this hypothesis , we investigated the effects of enforced DNMT3B7 expression in neuroblastoma cells , finding a significant inhibition of cell proliferation in vitro and angiogenesis and tumor growth in vivo . DNMT3B7-positive cells had higher levels of total genomic methylation and a dramatic decrease in expression of the FOS and JUN family members that comprise AP1 transcription factors . Consistent with an established antagonistic relationship between AP1 expression and retinoic acid receptor activity , increased differentiation was seen in the DNMT3B7-expressing neuroblastoma cells following treatment with all-trans retinoic acid ( ATRA ) compared to controls . Our results indicate that DNMT3B7 modifies the epigenome in neuroblastoma cells to induce changes in gene expression , inhibit tumor growth , and increase sensitivity to ATRA .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis;sustaining proliferative signaling" } ]

However , the clinical implications of Msx2 expression in breast cancer are unclear . The aims of this study were to investigate the potential clinical value of Msx2 as a breast cancer biomarker and to clarify its functional role in vitro . METHODS Msx2 gene expression was first examined in a well-validated breast cancer transcriptomic dataset of 295 patients . Msx2 protein expression was then evaluated by immunohistochemistry in a tissue microarray ( TMA ) containing 281 invasive breast tumours . Finally , to assess the functional role of Msx2 in vitro , Msx2 was ectopically expressed in a highly invasive breast tumour cell line ( MDA-MB-231 ) and an immortalised breast cell line ( MCF10a ) , and these cell lines were examined for changes in growth rate , cell death and cell signalling . RESULTS Examination of Msx2 mRNA expression in a breast cancer transcriptomic dataset demonstrated that increased levels of Msx2 were associated with good prognosis ( P = 0.011 ) . Evaluation of Msx2 protein expression on a TMA revealed that Msx2 was detectable in both tumour cell nuclei and cytoplasm . Cytoplasmic Msx2 expression was associated with low grade tumours ( P = 0.012 ) and Ki67 negativity ( P = 0.018 ) . Nuclear Msx2 correlated with low-grade tumours ( P = 0.015 ) , estrogen receptor positivity ( P = 0.038 ) , low Ki67 ( P = 0.005 ) and high cyclin D1 expression ( P = 0.037 ) . Increased cytoplasmic Msx2 expression was associated with a prolonged breast cancer-specific survival ( P = 0.049 ) , recurrence-free survival ( P = 0.029 ) and overall survival ( P = 0.019 ) . Ectopic expression of Msx2 in breast cell lines resulted in radically decreased cell viability mediated by induction of cell death via apoptosis . Further analysis of Msx2-expressing cells revealed increased levels of p21 and phosphorylated extracellular signal-regulated kinase ( ERK ) and decreased levels of Survivin and the ' split ends ' ( SPEN ) protein family member RBM15 . CONCLUSIONS We conclude that increased Msx2 expression results in improved outcome for breast cancer patients , possibly by increasing the likelihood of tumour cell death by apoptosis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death;evading growth suppressors" } ]

A common genetic mutation found in ccRCC is the loss of the von Hippel-Lindau ( VHL ) gene , which contributes to cancer progression and metastasis . We investigated VIP effects on metastatic and angiogenic factors in human VHL-null A498 ccRCC and HK2 renal cells . VIP increased adhesion but decreased expression of metalloproteinases , MMP2 and MMP9 , as well as cell migration and VEGF expression and secretion in A498 but not in HK2 cells . VIP enhanced ROS levels and decreased nuclear levels of β-catenin and NFκB p50-subunit in A498 cells , suggesting neuropeptide involvement in the observed decrease of metastatic ability in clear-cell carcinoma . VIP effects in A498 cells were blocked by the VPAC(1/2)-receptor antagonist JV-1-53 . In conclusion , present data point to a role of VIP in preventing invasion and metastasis in ccRCCs and support its potential therapeutic usefulness in this disease .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;inducing angiogenesis;tumor promoting inflammation" } ]

The erythrocytes with these surface modifications undergo macrophage-mediated phagocytosis . In this study , the role of protein kinase C ( PKC ) isoforms in the expression of these surface modifications was investigated . Inhibition of PKC α by 30 μM rottlerin ( R30 ) and 2.3 nM G� 6976 caused expression of both the senescent cell marker-externalized PS measured by FACS analysis and aggregated band 3 detected by western blotting . In contrast to this observation , but in keeping with literature , PKC activation by phorbol-12-myristate-13-acetate ( PMA ) also led to the expression of senescence markers . We explain this antithesis by demonstrating that PMA-treated cells show reduction in the activity of PKC α , thereby simulating inhibition . The reduction in PKC α activity may be attributed to the known downregulation of PMA-activated PKC α , caused by its membrane translocation and proteolysis . We demonstrate membrane translocation of PKC α in PMA-treated cells to substantiate this inference . Thus loss of PKC α activity either by inhibition or downregulation can cause surface modifications which can trigger erythrophagocytosis .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

The neutrophil-to-lymphocyte ratio ( NLR ) in blood is an easily assessable parameter of systemic inflammatory response . The aim of this study was to determine whether the NLR is prognostic in GIST . METHODS : A total of 339 previously untreated patients with primary , localized GIST operated at our institution between 1995 and 2010 were identified from a prospectively collected sarcoma database . NLR was assessed preoperatively . Patients who received adjuvant imatinib treatment were excluded from the analysis ( n=64 ) . Cox regression models were calculated and correlation analyses were performed . RESULTS : On univariate analysis , NLR was associated with recurrence-free survival ( RFS ) ( P=0.003 , hazard ratio 3.3 , 95% confidence interval 1.5-7.4 ) . Patients with a low NLR had a 1- and 5-year RFS of 98 and 91% , compared with 89 and 76% in those with a high NLR . The median RFS was not reached . Positive correlations were found between NLR and mitotic rate ( Pearson correlation coefficient [ r]=0.15 , P=0.03 ) , and NLR and tumor size ( r=0.36 , P=0.0001 ) . RFS in patients with a GIST>5cm with low NLR was significantly longer compared to patients with high NLR ( P=0.002 ) . Flow cytometry analysis of freshly obtained GISTs revealed that neutrophils constituted a minimal percentage of intratumoral immune cells . CONCLUSIONS : NLR is a surrogate for high-risk tumor features . Elevated blood NLR appears to represent systemic inflammation in patients with high-risk GIST .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction;tumor promoting inflammation" } ]

Gene therapy could be a potentially effective therapy for ACC and its metastasis . The aims of the study were : To transduce interleukin-2 ( IL-2 ) gene into an ACC cell line with predisposition for lung metastasis ( ACC-M ) ; to compare the bioactivity of the gene-transduced cells and the parent cell line in vitro and in vivo . The IL-2 gene was transduced via a bicistronic retroviral vector into the ACC-M cells . The growth rate and DNA cell cycles of the parent ACC-M , the control viral vector AmGCEN , and the gene transduced AmIL-2 cell cultures were compared quantitatively and by flow cytometry , respectively . The tumourigenic ability of the three cell lines was verified by inoculation in athymic nude mice . The tumours developed were extracted and compared quantitatively and histologically . There was no difference in the growth rate and the DNA count between the ACC-M , AmGCEN , and AmIL-2 cell cultures . In the animal experiment , both the ACC-M and AmGCEN cells stimulated lung metastasis in all the mice , whereas there was no tumour found in the 1 x 10(6) AmIL-2 cells inoculation . On 3 x 10(6) AmIL-2 cells stimulation , three out of six mice developed tumours but the mass and volume of the tumours were smaller than the other two groups . Under light microscopy , the ACC-M tumours were mainly poorly differentiated with minimal cellular matrix , whereas the AmIL-2 tumours were well differentiated with ample matrix . The transduction of IL-2 gene can reduce the tumourigenicity of ACC-M cells and induces tumour cell differentiation in mice .

In mouse models , enforced retroviral expression of Hoxa9 alone in marrow is not sufficient to cause rapid AML , while co-expression of Meis1 and Hoxa9 induces rapid AML . In contrast , retroviral expression of Nup98-HoxA9 is sufficient to cause rapid AML in the absence of enforced Meis1 expression . Previously , we demonstrated that Hoxa9 could block the differentiation of murine marrow progenitors cultured in granulocyte-macrophage colony-simulating factor ( GM-CSF ) . These progenitors lacked Meis1 expression , could not proliferate in stem cell factor ( SCF ) , but could differentiate into neutrophils when switched into granulocyte colony-simulating factor ( G-CSF ) . Ectopic expression of Meis1 in these Hoxa9 cells suppressed their G-CSF-induced differentiation , permitted proliferation in SCF , and therein offered a potential explanation of cooperative function . Because Meis1 binds N-terminal Hoxa9 sequences that are replaced by Nup98 , we hypothesized that Nup98-HoxA9 might consolidate the biochemical functions of both Hoxa9 and Meis1 on target gene promoters and might evoke their same lymphokine-responsive profile in immortalized progenitors . Here we report that Nup98-HoxA9 , indeed mimicks Hoxa9 plus Meis1 coexpression - it immortalizes myeloid progenitors , prevents differentiation in response to GM-CSF , IL-3 , G-CSF , and permits proliferation in SCF . Unexpectedly , however , Nup98-Hoxa9 also enforced strong transcription of the cellular Hoxa9 , Hoxa7 and Meis1 genes at levels similar to those found in mouse AML's generated by proviral activation of Hoxa9 and Meis1 . Using Hoxa9(-/-) marrow , we demonstrate that expression of Hoxa9 is not required for myeloid immortalization by Nup98-HoxA9 . Rapid leukaemogenesis by Nup98-HoxA9 may therefore result from both the intrinsic functions of Nup98-HoxA9 , as well as of those of coexpressed HOX and MEIS1 genes .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

Breast tumor cells that overexpress MAP17 show an increased tumoral phenotype with enhanced proliferative capabilities both in the presence or the absence of contact inhibition , decreased apoptotic sensitivity , and increased migration . MAP17-expressing clones also grow better in nude mice . The increased malignant cell behavior induced by MAP17 is associated with an increase in reactive oxygen species ( ROS ) production , and the treatment of MAP17-expressing cells with antioxidants results in a reduction in the tumorigenic properties of these cells . The MAP17-dependent increase in ROS and tumorigenesis relies on its PDZ-binding domain because disruption of this sequence by point mutations abolishes the ability of MAP17 to enhance ROS production and tumorigenesis . MAP17 is overexpressed in a great variety of human carcinomas , including breast tumors . Immunohistochemical analysis of MAP17 during cancer progression demonstrates that overexpression of the protein strongly correlates with tumoral progression . Generalized MAP17 overexpression in human carcinomas indicates that MAP17 can be a good marker for tumorigenesis and , especially , for malignant progression .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;genomic instability and mutation" } ]

The pattern and spectra of TP53 mutations often differ between cancer types , perhaps due to different etiological factors . The Hupki ( human TP53 knock-in ) mouse embryo fibroblast ( HUF ) immortalization assay is useful for studying mutagenesis in the human TP53 gene by environmental carcinogens . Prior to initiating an immortalization assay , carcinogen treatment conditions must be optimized , which can require a large number of cells . As primary HUF cultures senesce within 2 weeks , restricting their use , we investigated whether immortalized HUFs retaining wild-type TP53 can be surrogates for primary HUFs in initial treatment optimization . DNA damage by eight compounds found in diesel exhaust , benzo[a]pyrene , 3-nitrobenzanthrone , 1-nitropyrene , 1,3-dinitropyrene , 1,6-dinitropyrene , 1,8-dinitropyrene , 6-nitrochrysene , and 3-nitrofluorene , was assessed by ( 32 ) P-postlabeling and the alkaline comet assay in primary HUFs and in an immortal HUF cell line J201 . For most compounds , higher levels of DNA adducts accumulated in J201 cells than in primary HUFs . This difference was not reflected in the comet assay or by cell viability changes . Experiments in three additional immortal HUF cell lines ( AAI49 , U56 , and E2-143 ) confirmed strong differences in DNA adduct levels compared with primary HUFs . However , these did not correlate with the protein expression of Nqo1 or Nat1/2 , or with gene expression of Cyp1a1 or Cyp1b1 . Our results show that using immortal HUFs as surrogates for primary HUFs in genotoxicity screening has limitations and that DNA adduct formation is the best measure of genotoxicity of the nitro-polycyclic aromatic hydrocarbons tested in HUFs .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]
