The phosphorylated STAT1 translocates to the nucleus , where it turns on specific sets of IFN-gamma-inducible genes , such as the interferon regulatory factor ( IRF)-1 . We show here that gamma irradiation reduces the IFN-gamma mRNA expression . The inhibition of the STAT1 phosphorylation and the IRF-1 expression by gamma irradiation was also observed . In contrast , the mRNA levels of IL-5 and transcription factor GATA-3 were slightly induced by gamma irradiation when compared to the non-irradiated sample . Furthermore , we detected the inhibition of cell-mediated immunity by gamma irradiation in the allogenic-mixed lymphocytes ' reaction ( MLR ) . These results postulate that gamma irradiation induces the polarized-Th2 response and interferes with STAT1 signals , thereby causing the immunosuppression of the Th1 response .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

Ages ranged from 10 months to 17 years and there were 15 girls . Pathology was centrally reviewed and showed polymorphic features in 5 cases , monomorphic in 23 , mixed pattern in 5 patients and 9 other types . Using the Revised European-American Classification of Lymphoid Neoplasms , 5 were B lymphoblastoid , 24 were high-grade B and 14 were other subtypes . Using the Pittsburgh classification , 9 were lymphadenopathic , 10 were systemic , 25 were lymphomatous and , with the Murphy grouping for non-Hodgkin's lymphoma ( NHL ) , 10 were localized and 32 non-localized . Twenty-four out of 38 evaluable cases were Epstein-Barr virus positive . Thirty-five patients were evaluable for clonality ; 24 were monoclonal and 11 were polyclonal . Reduced immunosuppression in solid organ transplant patients resulted in resolution of disease in 14/24 , which was sustained in 11 . Nineteen patients received chemotherapy , 14/18 evaluable responded , which was sustained in 8 cases . Seven out of 29 solid organ transplant and 10/13 other immune-deficient patients died . In the largest group of patients , solid organ transplants , no significant clinical or biological characteristics that predicted outcome were identified .

We have previously shown that this mutant receptor , called DeltaEGFR , confers enhanced tumorigenicity to glioblastoma cells through elevated proliferation and reduced apoptotic rates of the tumor cells in vivo . To understand the molecular mechanisms that underlie DeltaEGFR-enhanced proliferation , we examined the gene products that control cell cycle progression . We found that levels of the cyclin-dependent kinase ( CDK ) inhibitor , p27 , were lower in U87MG.DeltaEGFR tumors than in parental U87MG or control U87MG.DK tumors . Consequently , CDK2-cyclin A activity was also elevated , concomitant with the RB protein hyperphosphorylation . In addition , activated phosphatidylinositol 3-kinase ( PI3-K ) and phosphorylated Akt levels were also elevated in the U87MG.DeltaEGFR tumors . U87MG.DeltaEGFR cells failed to arrest in G(1) in response to serum starvation in vitro and while maintaining high levels of PI3-K activity and hyperphosphorylated RB . Treatment of U87MG.DeltaEGFR cells with LY294002 , a PI3-K inhibitor , caused reduced levels of phosphorylated Akt and concomitantly up-regulated levels of p27 . Expression of a kinase dead dominant-negative Akt mutant in the U87MG.DeltaEGFR cells similarly resulted in up-regulation of p27 and down-regulation of tumorigenicity in vivo . These results suggest that the constitutively active DeltaEGFR can enhance cell proliferation in part by down-regulation of p27 through activation of the PI3-K/Akt pathway . This pathway may represent another therapeutic target for treatment of those aggressive glioblastomas expressing DeltaEGFR .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

This invasiveness is in contrast to normal mesenchymal cells that retract on contact with another cell . Why cancer cells are defective in contact inhibition of locomotion is not understood . Here , we analyse the dynamics of prostate cancer cell lines co-cultured with fibroblasts , and demonstrate that a combinatorial code of Eph receptor activation dictates whether cell migration will be contact inhibited . The unimpeded migration of metastatic PC-3 cells towards fibroblasts is dependent on activation of EphB3 and EphB4 by ephrin-B2 , which we show activates Cdc42 and cell migration . Knockdown of EphB3 and EphB4 restores contact inhibition of locomotion to PC-3 cells . Conversely , homotypic collisions between two cancer cells results in contact inhibition of locomotion , mediated by EphA-Rho-Rho kinase ( ROCK ) signalling . Thus , the migration of cancer cells can switch from restrained to invasive , depending on the Eph-receptor profile of the cancer cell and the reciprocal ephrin ligands expressed by neighbouring cells .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;activating invasion and metastasis" } ]

Several reports have shown that the AhR plays an important role in the control of cell-cycle progression , and this function is thought to be partly associated with the tumor promotion activity of dioxin . However , the underling mechanisms are not fully understood . We have previously shown that overexpression of AhR , as well as AhR ligand treatment , stimulates cell proliferation of human lung cancer A549 cells . In AhR-activated cells , the expression levels of DNA synthesis-related genes such as proliferating cell nuclear antigen ( PCNA ) and RFC38 are notably increased . Expression of these genes is mainly regulated by E2F1 , a transcription factor that is crucial for transition of the cell cycle from G1 to S phase . We show here that the transcriptional activity of E2F1 is increased by the AhR agonist treatment and that this effect depends on the presence of AhR . Functional mapping of AhR showed that the Per-Arnt-Sim ( PAS ) B domain is required for promotion of E2F1 activity . The mechanism involves formation of a complex of AhR and E2F1 on the regulatory region in the E2F1 target gene , followed by recruitment of coactivator activator for thyroid hormone and retinoid receptors ( ACTR ) . Consequently , the results in this study indicate the physiological function of AhR as a potent transcriptional coactivator of E2F1-dependent transcription and implicate the AhR-E2F1 interaction as a part of the mechanism by which AhR/Arnt promotes cell proliferation .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

METHODS The SHEE cell series consisted of immortalized embryonic esophageal epithelium which was in malignant transformation when cultivated over sixty passages without co-carcinogens . Cells of the 10th , 31st , 60th and 85th passages were present in progressive development after being transfected with HPV . Cells were cultivated in a culture flask and 24-hole cultural plates . Progressive changes of morphology , cell growth , contact-inhibition , and anchorage-dependent growth characteristics were examined by phase contrast microscopy . The cell proliferation rate was assayed by flow cytometry . The modal number of chromosomes was analyzed . HPV18E(6)E(7) was detected by Western blot methods and activities of telomerase were analyzed by TRAP . Tumorigenicity of cells was detected with soft agar plates cultivated and with tumor formation in SCID mice . RESULTS In morphological examination the 10th passage cells were in good differentiation , the 60th and 85th passages cells were in relatively poor differentiation , and the 31st passage cells had two distinct differentiations . The characteristics of the 85th and 60th passage cells were weakened at contact-inhibition and anchorage-dependent growth . Karyotypes of four stages of cells belonged to hyperdiploid or hypotriploid , and bimodal distribution of chromosomes appeared in the 31st and 60th passage cells . All of these characteristics combined with a increasing trend . The activities of telomerase were expressed in the latter three passages . Four fourths of SCID mice in the 85th passage cells and one fourth of SCID mice in the 60th passage cells developed tumors , but the cells in the 10th and 31st passage displayed no tumor formation . CONCLUSION In continual cultivation of fetal esophageal epithelial cells with transduction of HPV18E(6)E(7) , cells from the 10th to the 85th passage were changed gradually from preimmortal , immortal , precancerous to malignantly transformed stages . All of these changes were in a dynamic progressive process . The establishment of a continuous line of esophageal epithelium may provide a in vitro model of carcinogenesis induced by HPV .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;enabling replicative immortality" } ]

Our results show that SKI-606 and Iressa inhibit cell proliferation and provoke G(0)-G(1) cell cycle arrest and reduction of S and G(2)-M phase using 2 and 5 μM concentrations of these inhibitors . In contrast , SKI-606 induces differentiation to an epithelial phenotype \" mesenchymal-epithelial transition \" ; thus SKI-606 causes a dramatic decrease in cell motility and invasion abilities of HeLa and SiHa cancer cells , in comparison to untreated cells and Iressa-treated cells in which these parameters are only slightly affected . These changes are accompanied by a regulation of the expression patterns of E-cadherin and catenins . The molecular pathway analysis of Src/Abl inhibitor revealed that SKI-606 blocks the phosphorylation of β-catenin and consequently converts its role from a transcriptional regulator to a cell-cell adhesion molecule . Our findings indicate that SKI-606 inhibits signaling pathways involved in regulating tumor cell migration and invasion genes via β-catenin alteration , suggesting that Src inhibitor , in comparison to EGF-R , is a promising therapeutic agent for human cervical cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;activating invasion and metastasis" } ]

We developed a novel genetically engineered fibroblast cell line that completely prevents tumor formation in mice , with a 100% protection rate . No host side effects were apparent.This could represent a viable cellular strategy for preventing and treating a variety of human cancers . More specifically , we examined the autocrine and paracrine effects of the cellular delivery of TNF-alpha on breast cancer tumor growth and cancer metabolism . For this purpose , we recombinantly overexpressed TNF-alpha in human breast cancer cells ( MDA-MB-231 ) or human immortalized fibroblasts ( hTERT-BJ1 ) . Our results directly show that TNF-alpha functions as a potent tumor suppressor . Remarkably , TNF-alpha-expressing breast cancer cells were viable , without any significant increases in their basal apoptotic rate . However , after 4 weeks post-implantation , TNF-alpha-expressing breast cancer cells failed to form any tumors in xenografted mice ( 0 tumors/10 injections ) , ultimately conferring 100% protection against tumorigenesis . Similarly , TNF-alpha-overexpressing fibroblasts were also viable , without any increases in apoptosis . Significantly , complete tumor suppression was obtained by co-injecting TNF-alpha expressing stromal fibroblasts with human breast cancer cells , indicating that paracrine cell-mediated delivery of TNF-alpha can also prevent tumor engraftment and growth ( 0 tumors/10 injections ) . Mechanistically , TNF-alpha induced autophagy and mitochondrial dysfunction in both epithelial cancer cells and stromal fibroblasts , preventing energy transfer from the tumor microenvironment , likely \" starving \" the cancer cells to death . In addition , via qRT-PCR analysis of MDA-MB-231 cells , we observed that TNF-alpha mediated the up-regulation of gene transcripts associated with inflammation and senescence [ IL-1-beta , IL-6 , IL-8 , MCP-1 , COX-2 , p21(WAF1/CIP1) ] and downregulated known tumor-promoting genes ( collagen VI and MMP2 ) . Recombinant overexpression of TNF-alpha receptor(s) in MDA-MB-231 cells also significantly reduced tumor growth , but was not as effective as the TNF-alpha ligand itself in preventing tumor growth . Thus , we propose that stromal cell-mediated delivery of TNF-alpha to human tumors [ using transfected fibroblasts or mesenchymal stem cells ( hMSCs) ] may be a novel and effective strategy for the prevention and treatment of human cancers .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;enabling replicative immortality;tumor promoting inflammation" } ]

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

We report here that eukaryotic elongation factor-2 kinase ( EEF2K ) is a critical controller of the ER stress-induced autophagy and apoptosis in tumor cells . DDIT4 , a stress-induced protein , was required for transducing the signal for activation of EEF2K under ER stress . We further showed that phosphorylation of EEF2K at Ser398 was essential for induction of autophagy , while phosphorylation of the kinase at Ser366 and Ser78 exerted an inhibitory effect on autophagy . Suppression of the ER stress-activated autophagy via silencing of EEF2K aggravated ER stress and promoted apoptotic cell death in tumor cells . Moreover , inhibiting EEF2K by either RNAi or NH125 , a small molecule inhibitor of the enzyme , rendered tumor cells more sensitive to curcumin and velcade , two anticancer agents that possess ER stress-inducing action . Our study indicated that the DDIT4-EEF2K pathway was essential for inducing autophagy and for determining the fate of tumor cells under ER stress , and suggested that inhibiting the EEF2K-mediated autophagy can deteriorate ER stress and lead to a greater apoptotic response , thereby potentiating the efficacy of the ER stress-inducing agents against cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

They were hairpin-shaped oligonucleotides , each containing an isomer of thymine glycol or 5,6-dihydrothymine as a damaged base in the center , with a fluorophore and a quencher at the 5'- and 3'-ends , respectively . Fluorescence was detected when the phosphodiester linkage at the damage site was cleaved by the enzyme , because the short fragment bearing the fluorophore could not remain in a duplex form hybridized to the rest of the molecule at the incubation temperature . The substrate specificities of Escherichia coli endonuclease III and its human homolog , NTH1 , determined by using these probes agreed with those determined previously by gel electrophoresis using ( 32)P-labeled substrates . Kinetic parameters have also been determined by this method . Since different fluorophores were attached to the oligonucleotides containing each lesion , reactions with two types of substrates were analyzed separately in a single tube , by changing the excitation and detection wavelengths . These probes were degraded during an incubation with a cell extract . Therefore , phosphorothioate linkages were incorporated to protect the probes from nonspecific nucleases , and the base excision repair activity was successfully detected in HeLa cells .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Evidence gained from studies on several in vivo animal models has firmly established a causal connection between aberrant PDGF signaling and the formation of some gliomas . However , only recently has significant knowledge been gained regarding crucial issues such as the glioma cell of origin and the relationship between the transforming stimulus and the cellular characteristics of the resulting tumor . Based on recent evidence , we propose that PDGF can bias cell-fate decisions , driving the acquisition of cell type-specific features by the progeny of multipotent neural progenitors , thus determining the shape and direction of the transformation path . Furthermore , recent data about the cellular mechanisms of PDGF-driven glioma progression and maintenance indicate that PDGF may be required , unexpectedly , to override cell contact inhibition and promote glioma cell infiltration rather than to stimulate cell proliferation .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

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

To determine if RARbeta2 suppresses proliferation of mammary-derived cancer cells in vivo , we transduced MDA-MB-435 breast cancer cells with the LXSN retroviral vector containing RARbeta2 and implanted LXSN vector- or RARbeta2-transduced cells into the mammary fat pads of nude and severe combined immune deficiency ( SCID ) mice . We analyzed the xenografts for several tumor parameters , including tumor size , inflammation , vascularity , mitoses , tumor recurrence at the primary site following resection , and metastases . We found that 19 of 52 mice inoculated with vector-transduced cells developed metastases in multiple organs while only one of 55 mice receiving RARbeta2-transduced cells displayed evidence of metastases ( p &lt ; 0.000001 , combined experiments , two-tailed Fisher's exact test ) . Moreover , RARbeta2-tumor cell recipient mice had a lower incidence of post-resection tumor recurrence ( 8/55 vs. 25/52 , p = 0.0004 ) , 34% less necrosis ( in three of four experiments , p = 0.001 ) , and 39% fewer mitoses in tumor tissue ( p &lt ; 0.000001 ) .

METHODS Localization of the fatty acid hydrolytic enzyme ( FAAH ) , cannabinoid receptors 1(CB1) and cannabinoid receptors 2 ( CB2 ) proteins was detected in L02 and HepG2 cells using immunofluorescence . L02 and HepG2 cells were treated with different concentrations of AEA and methyl-beta-cyclodextrin , and the rates of cells necrosis were examined by PI stain . Meanwhile , the expression levels of FAAH , CB1 and CB2 receptor proteins , as well as P38 mitogen-activated protein kinase ( p-P38 MAPK ) and c-Jun-NH2-terminal kinase ( p-JNK ) proteins , were analyzed by Western blot . RESULTS The FAAH , CB1 and CB2 receptor proteins were observed both in cytoplasm and on membrane in L02 and HepG2 cells . The expression level of FAAH protein was higher in HepG2 than in L02 cells . The expression level of CB1 receptor protein was very low in both L02 and HepG2 cells . The expression level of CB2 receptor protein was high in both L02 and HepG2 cells . AEA treatment induced necrosis in HepG2 cells but not in L02 cells . Methyl-beta-cyclodextrin treatment prevented necrosis in HepG2 cells ( t = 3.702 ; 5.274 ; 3.503 , P less than 0.05 ) . The expression patterns of FAAH , CB1 and CB2 receptor protein in L02 and HepG2 cells were confirmed by western blot , which were consistent with the immunofluorescence results . AEA treatment increased the levels of p-P38MAPK and p-JNK proteins in a dose-dependent manner in HepG2 cells ( F = 11.908 ; 26.054 , P less than 0.05 ) and the increase can be partially by prevented by MCD ( t = 2.801 ; t = 12.829 , P less than 0.05 ) .

EMT plays a major role in cancer metastasis , allowing individual cells to detach from the primary tumor , invade local tissue , and colonize distant tissues with new tumors . While invasion of vascular and lymphatic networks is the predominant route of metastasis , nerves also can act as networks for dissemination of cancer cell to distant sites in a process termed perineual invasion ( PNI ) . Signaling between nerves and invasive cancer cells remains poorly understood , as does cellular decision making that selects the specific route of invasion . Here we examine how HGF signaling contributes to PNI using reductionist culture model systems . We find that TGFβ , produced by PC12 cells , enhances scattering in response to HGF stimulation , increasing both cell-cell junction disassembly and cell migration . Further , gradients of TGFβ induce migratory mesenchymal cells to undergo chemotaxis towards the source of TGFβ . Interestingly , VEGF suppresses TGFβ-induced enhancement of scattering . These results have broad implications for how combinatorial growth factor signaling contributes to cancer metastasis , suggesting that VEGF and TGFβ might modulate HGF signaling to influence route selection during cancer progression .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;activating invasion and metastasis" } ]

We therefore examined the role of cyclin E2 in antiestrogen resistance in vitro and its potential for therapeutic targeting through cyclin-dependent kinase ( CDK ) inhibition . High expression of CCNE2 , but not CCNE1 , was characteristic of the luminal B and HER2 subtypes of breast cancer and was strongly predictive of shorter distant metastasis-free survival following endocrine therapy . After antiestrogen treatment of MCF-7 breast cancer cells , cyclin E2 mRNA and protein were downregulated and cyclin E2-CDK2 activity decreased . However , this regulation was lost in tamoxifen-resistant ( MCF-7 TAMR ) cells , which overexpressed cyclin E2 . Expression of either cyclin E1 or E2 in T-47D breast cancer cells conferred acute antiestrogen resistance , suggesting that cyclin E overexpression contributes to the antiestrogen resistance of tamoxifen-resistant cells . Ectopic expression of cyclin E1 or E2 also reduced sensitivity to CDK4 , but not CDK2 , inhibition . Proliferation of tamoxifen-resistant cells was inhibited by RNAi-mediated knockdown of cyclin E1 , cyclin E2 , or CDK2 . Furthermore , CDK2 inhibition of E-cyclin overexpressing cells and tamoxifen-resistant cells restored sensitivity to tamoxifen or CDK4 inhibition . Cyclin E2 overexpression is therefore a potential mechanism of resistance to both endocrine therapy and CDK4 inhibition .

In order to identify their molecular targets in such cells , we have analyzed gene expression profile of primary human macrophages treated by the prototypical PAH benzo(a)pyrene ( BaP ) , using pangenomic oligonucleotides microarrays . Exposure of macrophages to BaP for 8 and 24 h resulted in 96 and 1100 genes , differentially expressed by at least a twofold change factor , respectively . Some of these targets , including the chemokine receptor CXCR5 , the G protein-coupled receptor 35 ( GPR35 ) , and the Ras regulator RASAL1 , have not been previously shown to be affected by PAHs , in contrast to others , such as interleukin-1beta and the aryl hydrocarbon receptor ( AhR ) repressor . These BaP-mediated gene regulations were fully validated by reverse transcription-quantitative polymerase chain reaction assays for some selected genes . Their bioinformatic analysis indicated that biological functions linked to immunity , inflammation , and cell death were among the most affected by BaP in human macrophages and that the AhR and p53 signaling pathways were the most significant canonical pathways activated by the PAH . AhR and p53 implications were moreover fully confirmed by the prevention of BaP-related upregulation of some selected target genes by AhR silencing or the use of pifithrin-alpha , an inhibitor of PAH bioactivation-related DNA damage/p53 pathways . Overall , these data , through identifying genes and signaling pathways targeted by PAHs in human macrophages , may contribute to better understand the molecular basis of the immunotoxicity of these environmental contaminants .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;genomic instability and mutation;avoiding immune destruction" } ]

METHODS The effects of TMZ and BG on apoptosis , cell growth , the mitotic index , cell cycle distribution , and protein expression were studied by TUNEL , cell counting , flow cytometry , and Western blot analysis , respectively . RESULTS The wt-p53 human pancreatic tumor cell line Capan-2 and p53-efficient mouse embryonic fibroblasts ( MEFs ) were more responsive to treatment with TMZ + BG than mutant p53 Capan-1 and p53-null MEFs . S phase delay with a subsequent G2/M arrest was observed in Capans in response to BG + TMZ . The G1-to-S transition delay in Capan-2 was associated with p53-dependent apoptosis and was distinctly different from the presumed mismatch repair ( MMR ) killing operative during the G2/M arrest . The effect of p53 on BG + TMZ toxicity was supported by a marked change in apoptosis when p53 function was restored/inactivated . There was an early induction of MMR proteins in p53-efficient lines . CONCLUSION p53 provokes a classic proapoptotic response by delaying G1-to-S progression , but it may also facilitate cell killing by enhancing MMR-related cell cycle arrest and cell death .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;genomic instability and mutation;resisting cell death" } ]

RAD51 mRNA expression levels are significantly increased in laser-microdissected mammary simple carcinomas and their lymph node metastases when compared to adenomas or nonneoplastic mammary gland of the same dog . Here , RAD51 protein expression was analyzed by immunohistochemistry in paraffin-embedded mammary carcinomas and their lymph node metastases of 40 dogs , adenomas of 48 dogs , and nonneoplastic mammary gland of 88 dogs . Number of cells with nuclear RAD51 expression was significantly ( P &lt ; or = .05 ) increased in carcinomas when compared to adenomas and metastases . In contrast , no significant differences in the number of RAD51-expressing cells were detected when metastases were compared with adenomas and nonneoplastic gland . RAD51 expression in carcinomas was correlated with expression in metastases but not with histologic grade .

Although the role of Hsp27 in protection from stress-induced intrinsic cell death has been relatively well studied , its role in Fas ( death domain containing member of the tumor necrosis factor receptor superfamily)-induced apoptosis and cell proliferation remains underappreciated . Here , we show that Hsp27 silencing induces dual coordinated effects , resulting in inhibition of cell proliferation and sensitization of cells to Fas-induced apoptosis through regulation of PEA-15 ( 15-kDa phospho-enriched protein in astrocytes ) . We demonstrate that Hsp27 silencing suppresses proliferation by causing PEA-15 to bind and sequester extracellular signal-regulated kinase ( ERK ) , resulting in reduced translocation of ERK to the nucleus . Concurrently , Hsp27 silencing promotes Fas-induced apoptosis by inducing PEA-15 to release Fas-associating protein with a novel death domain ( FADD ) , thus allowing FADD to participate in death receptor signaling . Conversely , Hsp27 overexpression promotes cell proliferation and suppresses Fas-induced apoptosis . Furthermore , we show that Hsp27 regulation of PEA-15 activity occurs in an Akt-dependent manner . Significantly , Hsp27 silencing in a panel of phosphatase and tensin homolog on chromosome 10 ( PTEN ) wild-type or null cell lines , and in LNCaP cells that inducibly express PTEN , resulted in selective growth inhibition of PTEN-deficient cancer cells . These data identify a dual coordinated role of Hsp27 in cell proliferation and Fas-induced apoptosis via Akt and PEA-15 , and indicate that improved clinical responses to Hsp27-targeted therapy may be achieved by stratifying patient populations based on tumor PTEN expression .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling" } ]

Hyperactivation of PAR synthesis by poly(ADP-ribose) polymerase-1 ( PARP-1 ) occurs when cells deficient in DNA repair are exposed to genotoxic agents ; however , the function of this hyperactivation has not been adequately explained . Here , we examine PAR synthesis in mouse fibroblasts deficient in the base excision repair enzyme DNA polymerase β ( pol β ) . The extent and duration of PARP-1 activation was measured after exposure to either the DNA alkylating agent , methyl methanesulfonate ( MMS ) , or to low energy laser-induced DNA damage . There was strong DNA damage-induced hyperactivation of PARP-1 in pol β nullcells , but not in wild-type cells . In the case of MMS treatment , PAR synthesis did not lead to cell death in the pol β null cells , but instead resulted in increased PARylation of the nonhomologous end-joining ( NHEJ ) protein Ku70 and increased association of Ku70 with PARP-1 . Inhibition of the NHEJ factor DNA-PK , under conditions of MMS-induced PARP-1 hyperactivation , enhanced necrotic cell death . These data suggest that PARP-1 hyperactivation is a protective mechanism triggering the classical-NHEJ DNA repair pathway when the primary alkylated base damage repair pathway is compromised .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;resisting cell death" } ]

The present study aimed to investigate the role of exogenously added glutathione ( GSH ) on ( 12)C-beam ( 287keV/mum ) and ( 7)Li-beam ( 60keV/mum ) induced chromosome aberration ( CA ) formation , particularly on exchange aberration formation . In order to characterize the role of GSH in the joining of DNA DSBs , we induced DNA lesions with bleomycin ( Blem ) in conjunction with either high- or low-LET radiation ( X-rays ) since the chemistry of the free DNA ends created by Blem and X-rays is similar . CHO cells were exposed to reduced GSH at a concentration of 2mM for 3h before radiation . Treatment with Blem ( 20mug/ml ) was carried out for 2h before the cells were exposed to radiation . Our results show that the frequency of chromosomal aberration increases with increased LET . Heavy ion exposed cells show a higher frequency of CA over time than do X-irradiated cells . An analysis of the first post-irradiation mitosis of exposed CHO cells shows that high-LET radiation induces more breaks than exchange-type aberrations and exogenous GSH has no influence on high-LET radiation-induced DNA damage . The DNA lesions induced by low-LET radiation interact relatively strongly with Blem-induced lesions whereas interaction between Blem and high-LET radiations was poor . This could be attributed to differences in repair kinetics and qualitative differences in the DNA lesions induced by Blem and high-LET radiation .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

So far , the mechanisms leading to upregulation of TEM5 and its function during angiogenesis have not been identified . Here , we report that TEM5 expression in endothelial cells is induced during capillary-like network formation on Matrigel , during capillary morphogenesis in a three-dimensional collagen I matrix , and upon confluence on a two-dimensional matrix . TEM5 expression was not induced by a variety of soluble angiogenic factors , including VEGF and bFGF , in subconfluent endothelial cells . TEM5 upregulation was blocked by toxin B from Clostridium difficile , an inhibitor of the small GTPases Rho , Rac , and Cdc42 . The Rho inhibitor C3 transferase from Clostridium botulinum did not affect TEM5 expression , whereas the Rac inhibitor NSC23766 suppressed TEM5 upregulation . An excess of the soluble TEM5 extracellular domain or an inhibitory monoclonal TEM5 antibody blocked contact inhibition of endothelial cell proliferation resulting in multilayered islands within the endothelial monolayer and increased vessel density during capillary formation . Based on our results we conclude that TEM5 expression during capillary morphogenesis is induced by the small GTPase Rac and mediates contact inhibition of proliferation in endothelial cells .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis;evading growth suppressors" } ]

There are no robust data on prognostic factors for overall survival ( OS ) in patients with metastatic colorectal cancer treated with vascular endothelial growth factor ( VEGF)-targeted therapy . The present study was conducted to establish a prognostic model for patients using an oxaliplatin-based or irinotecan-based chemotherapy plus bevacizumab in metastatic colorectal cancer . METHODS Baseline characteristics and outcomes on 170 patients treated with FOLFIRI or XELOX plus anti-VEGF therapy-naive metastatic colorectal cancer were collected from three Turkey cancer centers . Cox proportional hazards regression was used to identify independent prognostic factors for OS . RESULTS The median OS for the whole cohort was 19 months ( 95% CI , 14.3 to 23.6 months ) . Three of the seven adverse prognostic factors according to the Anatolian Society of Medical Oncology ( ASMO ) were independent predictors of short survival : serum lactate dehydrogenase ( LDH ) greater than the upper limit of normal ( ULN ; p<0.001 ) ; neutrophils greater than the ULN ( p<0.0014 ) ; and progression free survival ( PFS ) less than 6 months ( p =0.001 ) . CONCLUSION Serum LDH and neutrophil levels were the main prognostic factors in predicting survival , followed by PFS .

However , it is not clear that emodin can induce growth inhibition of hepatoma cells . We have found that emodin induces apoptotic responses in the human hepatocellular carcinoma cell lines ( HCC ) Mahlavu , PLC/PRF/5 and HepG2 . The addition of emodin to these three cell lines led to inhibition of growth in a time- and dose-dependent manner . Emodin generated reactive oxygen species ( ROS ) in these cells which brought about a reduction of the intracellular mitochondrial transmembrane potential ( DeltaPsim ) , followed by the activation of caspase-9 and caspase-3 , leading to DNA fragmentation and apoptosis . Our findings demonstrate that ROS and the resulting oxidative stress play a pivotal role in apoptosis . Preincubation of hepatoma cell lines with the hydrogen peroxide-scavenging enzyme , catalase ( CAT ) and cyclosporin A ( CsA ) , partially inhibited apoptosis .

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

But several tumor cells , including leukemic cells , also increase glutamine metabolism , which is initiated by glutaminase ( GLS ) . The microRNA ( miRNA ) miR-23 targets GLS mRNA and inhibits expression of GLS protein . Here we show that in human leukemic Jurkat cells the NF-κB p65 subunit binds to miR-23a promoter and inhibits miR-23a expression . Histone deacetylase ( HDAC ) inhibitors release p65-induced inhibition . Jurkat cells growing in glutamine decrease proliferation due to cell accumulation in G0/G1 phase . Nevertheless , cells get used to this new source of energy by increasing GLS expression , which correlates with an increase in p65 expression and its translocation to the nucleus , leading to a higher basal NF-κB activity . Jurkat cells overexpressing p65 show increase basal GLS expression and proliferate faster than control cells in glutamine medium . Overexpressing miR-23a in leukemic cells impaired glutamine use and induces mitochondrial dysfunction leading to cell death . Therefore , p65 activation decreases miR-23a expression , which facilitates glutamine consumption allowing leukemic cells to use this alternative source of carbon and favoring their adaptation to the metabolic environment .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;cellular energetics" } ]

We recently reported the identification of a group of novel small compounds that inhibit basal glucose transport and reduce cancer cell growth by a glucose deprivation-like mechanism . We hypothesized that the compounds target Glut1 and are efficacious in vivo as anticancer agents . Here , we report that a novel representative compound WZB117 not only inhibited cell growth in cancer cell lines but also inhibited cancer growth in a nude mouse model . Daily intraperitoneal injection of WZB117 at 10 mg/kg resulted in a more than 70% reduction in the size of human lung cancer of A549 cell origin . Mechanism studies showed that WZB117 inhibited glucose transport in human red blood cells ( RBC ) , which express Glut1 as their sole glucose transporter . Cancer cell treatment with WZB117 led to decreases in levels of Glut1 protein , intracellular ATP , and glycolytic enzymes . All these changes were followed by increase in ATP-sensing enzyme AMP-activated protein kinase ( AMPK ) and declines in cyclin E2 as well as phosphorylated retinoblastoma , resulting in cell-cycle arrest , senescence , and necrosis . Addition of extracellular ATP rescued compound-treated cancer cells , suggesting that the reduction of intracellular ATP plays an important role in the anticancer mechanism of the molecule . Senescence induction and the essential role of ATP were reported for the first time in Glut1 inhibitor-treated cancer cells . Thus , WZB117 is a prototype for further development of anticancer therapeutics targeting Glut1-mediated glucose transport and glucose metabolism .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;enabling replicative immortality;resisting cell death;sustaining proliferative signaling" } ]

We find that incubating INS-1 cells with IL-1β and IFN-γ , with STZ , or with TBHP causes increased expression of iPLA(2)γ mRNA and protein . We prepared INS-1 knockdown ( KD ) cell lines with reduced iPLA(2)γ expression , and they proliferate more slowly than control INS-1 cells and undergo increased membrane peroxidation in response to cytokines or oxidants . Accumulation of oxidized phospholipid molecular species in STZ-treated INS-1 cells was demonstrated by LC/MS/MS scanning , and the levels in iPLA(2)γ-KD cells exceeded those in control cells. iPLA(2)γ-KD INS-1 cells also exhibited higher levels of apoptosis than control cells when incubated with STZ or with IL-1β and IFN-γ . These findings suggest that iPLA(2)γ promotes β-cell proliferation and that its expression is increased during inflammation or oxidative stress as a mechanism to mitigate membrane injury that may enhance β-cell survival .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

The development of BRCA1 tumors is likely to depend on additional genetic alterations and gene expression changes which follow growth and DNA repair defects associated with BRCA1 deficiency . The identification of these modifications offers an opportunity to find surrogate markers of BRCA1 tumors . Here , we sought to identify differentially expressed proteins related to BRCA1 depletion . EXPERIMENTAL DESIGN We used isogenic HeLa cells either stably knocked-down or not for BRCA1 ( BRCA1(KD) ) and compared protein profiles of these cells by DIGE . RESULTS We detected increased levels of Replication protein A2 ( RPA2 ) in BRCA1(KD) cells as compared to control cells . RPA2 is an essential protein required for DNA replication and repair . We further demonstrated that depletion of RPA2 subunit delays growth of BRCA1(KD) respect to isogenic control cells . Strikingly , elevated levels of RPA2 were more frequently observed in BRCA1 tumors when triple-negative tumors from BRCA1 mutation carriers ( n=13 ) and non-carriers ( n=36 ) were stained in situ for RPA2 . CONCLUSIONS AND CLINICAL RELEVANCE RPA2 up-regulation may thus be involved in the growth and/or survival of BRCA1 tumor cells and useful in immunohistochemical discrimination of triple-negative BRCA1 tumors .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

We have previously demonstrated that myeloma cells exhibit constitutive plasma membrane ( PM ) localization of GLUT4 , consistent with the dependence of MM cells on this transporter for maintenance of glucose consumption rates , proliferative capacity , and viability . The purpose of this study was to investigate the molecular basis of constitutive GLUT4 plasma membrane localization in MM cells . FINDINGS We have elucidated a novel mechanism through which myeloma cells achieve constitutive GLUT4 activation involving elevated expression of the Rab-GTPase activating protein AS160_v2 splice variant to promote the Warburg effect . AS160_v2-positive MM cell lines display constitutive Thr642 phosphorylation , known to be required for inactivation of AS160 Rab-GAP activity . Importantly , we show that enforced expression of AS160_v2 is required for GLUT4 PM translocation and activation in these select MM lines . Furthermore , we demonstrate that ectopic expression of a full-length , phospho-deficient AS160 mutant is sufficient to impair constitutive GLUT4 cell surface residence , which is characteristic of MM cells . CONCLUSIONS This is the first study to tie AS160 de-regulation to increased glucose consumption rates and the Warburg effect in cancer . Future studies investigating connections between the insulin/IGF-1/AS160_v2/GLUT4 axis and FDG-PET positivity in myeloma patients are warranted and could provide rationale for therapeutically targeting this pathway in MM patients with advanced disease .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

The present study was undertaken to establish the possibility of using a combination of specific oncogenic products , including epidermal growth factor receptor ( EGFR ) , pAkt , nuclear factor-kappaB ( NF-κB ) and macrophage inhibitory cytokine-1 ( MIC-1 ) as biomarkers and therapeutic targets for optimizing the management of patients with localized PC at earlier disease stages . The immunohistochemical and immunofluorescence data have revealed that the expression levels of EGFR , Ser(473)-pAkt , NF-κB p65 and MIC-1 proteins were significantly enhanced in the same subset of 76 cases of prostatic adenocarcinoma specimens during the disease progression and these biomarkers were expressed in a small subpopulation of CD133(+) PC cells and the bulk tumor mass of CD133(-) PC cells . Importantly , all of these biomarkers were also overexpressed in 80-100% of 30 PC metastasis bone tissue specimens . Moreover , the results have indicated that the EGF-EGFR signaling pathway can provide critical functions for the self-renewal of side population ( SP ) cells endowed with stem cell-like features from highly invasive WPE1-NB26 cells . Of therapeutic interest , the targeting of EGFR , pAkt , NF-κB or MIC-1 was also effective at suppressing the basal and EGF-promoted prostasphere formation by SP WPE1-NB26 cells , inducing disintegration of SP cell-derived prostaspheres and decreasing the viability of SP and non-SP WPE1-NB26 cell fractions . Also , the targeting of these oncogenic products induced the caspase-dependent apoptosis in chemoresistant SP WPE1-NB26 cells and enhanced their sensibility to the cytotoxic effects induced by docetaxel . These findings suggest that the combined use of EGFR , pAkt , NF-κB and/or MIC-1 may represent promising strategies for improving the accuracy of current diagnostic and prognostic methods and efficacy of treatments of PC patients in considering the disease heterogeneity , thereby preventing PC progression to metastatic and lethal disease states .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;sustaining proliferative signaling;resisting cell death" } ]

In this work , intratumoral perineural invasion , lymphatic and blood vessel invasion together with the necrosis content of the tumor exclusive of the non-small cell cancer staging system were studied . METHODS During a 4-year period , 152 patients operated for non-small cell lung cancer ( NSCLC ) at our hospital were analyzed . Mean age of patients was 55.7 +/- 10.1 years . RESULTS Overall 5-year survival was 42.2 % . Mediastinal lymph node involvement , tumor size , incomplete resection , pneumonectomy , presence of necrosis and perineural invasion were significant prognosticators ( P = 0.03 , 0.04 , 0.0001 , 0.046 , 0.0246 , &lt ; 0.0001 , respectively ) . Multivariate analysis revealed that N status , perineural invasion , and the presence of necrosis were independent prognostic factors ( P = 0.006 , P = 0.001 , P = 0.001 , respectively ) . Patients who had stage I tumor with necrosis and perineural invasion had a lower survival rate than those with stage IIIA tumor without these histopathological features ( P = 0.04 ) . The presence of these histopathological characteristics in stage IIIA patients was a sign of a poorer prognosis ( P = 0.0001 ) . CONCLUSIONS Perineural invasion and the presence of necrosis independently indicated a dismal prognosis and their prognostic power is comparable to those of the TNM classification . These factors could be candidates for better survival stratification and the indicators of the need for adjuvant therapy in early stage lung cancer patients .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;resisting cell death" } ]

In this study , we investigated the effects of overexpression of the MDA-7/IL-24 gene in human hepatocellular carcinoma ( HCC ) cells in vitro and in vivo . Adenovirus-mediated overexpression of MDA-7 facilitated the MDA-7/IL-24-induced apoptosis and G2/M arrest in HCC cells , but not in the normal liver cell line L02 , and the effect was independent of the p53 status . Inhibition of metastasis and angiogenesis was correlated with decreasing expression of STAT3 , P-STAT3 , MMP-2 , VEGF , and TGF-beta genes , regulated by STAT3 in MHCCLM6 cells . We also showed that Ad.mda-7 combined with doxorubicin ( ADM ) had significantly enhanced antitumor and antimetastatic effects in vivo , accompanied by the downregulation of VEGF , MMP-2 , and TGF-beta genes and the upregulation of E-cadherin genes . These data suggested that MDA-7/IL-24 induces its selective antitumor properties in HCC cells by promoting apoptosis independent of p53 status , inhibiting subcutaneous tumor growth and metastasis , and increasing the effect of chemotherapeutic agents .

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

We aimed at evaluating markers that reflect instability in esophageal malignancies , examine the prevalence of MSI in cancers and other pathologies of the esophagus , and determine the methylation status of hMLH1 gene in relation to MSI. 42% ( 21/50 ) cancers and 15.4%(2/13) precancers exhibited MSI where 85.7% cancers and 50% precancers with MSI , showed a hypermethylated hMLH1 promoter . Increased number of cases with repair gene methylation were seen with increasing severity of the esophageal pathology suggesting epigenetic progression parallels histologic changes . BAT25 and D3S1313 markers exhibited instability frequently and cases with MSI using these markers showed an abnormal hMLH1 promoter .

The aim of this study was to determine whether there was a correlation between the persistence of O6-methylguanine ( O6-mGua ) adducts and the rate of recovery of O6-methylguanine-DNA methyltransferase ( O6-mGuaT ) after depletion in the liver and susceptibility to NNK in F344 rat and Syrian golden hamster injected s.c. with NNK ( 80 mg/kg ) . The levels of both 7-methylguanine and O6-mGua reached a maximum 24 h after NNK treatment . O6-mGua in NNK-treated rat liver was undetectable after 48 h . In the rat , the depletion of O6-mGuaT activity occurred within 4 h following NNK treatment . A subsequent rapid recovery of enzyme activity was observed 36 h after NNK exposure . In contrast , high levels of O6-mGua persisted in hamster liver DNA and no O6-mGuaT activity was detected up to 336 h after NNK injection . Thus , the persistence of O6-mGua in hamster liver is most likely related to a lack of recovery of the O6-mGuaT . These results suggested that factors other than O6-mGua may be determining NNK-induced hepatocarcinogenesis in rats . An aldehyde generated by alpha-hydroxylation of NNK , 4-oxo-4-(3-pyridyl)butanal , inhibited O6-mGuaT activity in rat hepatocytes , suggesting that this aldehyde contributes to the carcinogenicity of NNK by inhibiting this repair enzyme .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Herein , we report the efficacy of a mixed-tocotrienol diet against prostate tumorigenesis in the transgenic adenocarcinoma mouse prostate ( TRAMP ) mouse model . Male TRAMP mice , 8 wk old , were fed 0.1% , 0.3% , or 1% mixed tocotrienols in AIN-76A diet up to 24 wk old . Likewise , a positive control group consisting of male TRAMP mice and a negative control group consisting of wild-type nontransgenic mice were fed regular AIN-76A diet up to 24 wk old . Our results show that mixed-tocotrienol-fed groups had a lower incidence of tumor formation along with a significant reduction in the average wet weight of genitourinary apparatus . Furthermore , mixed tocotrienols significantly reduced the levels of high-grade neoplastic lesions as compared to the positive controls . This decrease in levels of high-grade neoplastic lesions was found to be associated with increased expression of proapoptotic proteins BAD ( Bcl(2) antagonist of cell death ) and cleaved caspase-3 and cell cycle regulatory proteins cyclin dependent kinase inhibitors p21 and p27 . In contrast , the expression of cyclins A and E were found to be decreased in mixed-tocotrienol groups .

Evidences indicated that areca quid chewing may increase the risk of oral squamous cell carcinoma ( OSCC ) . This study was to investigate the role of MGMT expression in OSCCs and the normal oral tissues . METHODS Thirty-two OSCCs from areca quid chewers and ten normal oral tissue biopsy samples without areca quid chewing were analyzed by the immunohistochemistry for MGMT . Primary human oral keratinocytes ( HOKs ) were challenged with arecoline , the major alkaloid of areca nut , by Western blot . Nicotine , an important component of cigarette smoke , was added to find the possible regulatory mechanisms . RESULTS Significant association was observed between low MGMT expression and advanced clinical stage of OSCCs and lymph node metastasis ( P=0.03 ) . MGMT expression was significantly higher in patients only chewing areca quid than patients both chewing areca quid and smoking ( P=0.028 ) . Arecoline was found to elevate MGMT expression in a dose- and time-dependent manner . The addition of nicotine was found to enhance arecoline-induced MGMT expression . CONCLUSION Our results indicate that MGMT could be used clinically as a predictive marker for tumor processing , the potential for lymph node metastasis as well as advanced clinical stage . MGMT expression was significantly upregulated by arecoline in HOKs . Nicotine has a synergistic effect of arecoline-induced MGMT expression .

In this communication we compare the effect of iodide , molecular iodine and delta-iodolactone on growth inhibition and apoptosis on three human thyroid carcinoma cell lines ( B-CPAP cells , FTC-133 cells and 8505C cells ) as well as on human breast cancer cells ( MCF 7 ) . METHODS Thyroid carcinoma cells were cultured in Dulbecco's modified Eagle's medium ( DMEM ) and MCF 7 cells in Rowswell Park Memorial Institute ( RPMI ) culture medium , both containing 10% ( v/v ) Fetal Calf Serum ( FCS ) , until they were confluent . Around 2000 cells were then distributed in 12-well plates and grown for 48 h in either DMEM ( thyroid cancer cells ) or in RPMI medium ( MCF 7 cells ) both containing 5% FCS . Thereafter , different concentrations of iodide , iodine or delta-iodolactone were added for 24 h . Growth rate was estimated by cell counting in a Coulter Counter adapted for epithelial cells . Apoptosis was determined by a mitochondrial potential assay . RESULTS The growth rate of B-CPAP cells was unaffected by iodide , but was reduced by high concentreations of molecular iodine ( 100 and 500 microM ) . However , delta-iodolactone significantly reduced cell proliferation already with low concentrations ( 5 microM and 10 microM ) and further in a dose-dependent manner up to 82% . FTC-133 and 8505C cells were unaffected by iodide , iodine or delta-iodolactone . In contrast , in MCF 7 cells , molecular iodine ( 100 microM ) inhibited growth from 100% to 83% but delta-iodolactone ( 1 , 5 and 10 microM ) dose-dependently decreased growth rate from 100% to 82% and 62% , respectively . The inhibition of growth was through apoptosis , and not necrosis , as the amount of apoptotic cells corresponded to the growth inhibition . CONCLUSION delta-Iotaodolactone seems to be the main iodocompound which can inhibit growth and induce apoptosis in B-CPAP cells as well as in MCF 7 breast cancer cells .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

Cell-cycle re-entry , however , is known to contribute to neuronal apoptosis . Moreover , recent evidence demonstrates the expression of cell-cycle proteins in differentiated neurons under physiological conditions . The functional roles of such expression remain unclear . Since DNA repair is generally attenuated by differentiation in most cell types , the cell-cycle-associated events in postmitotic cells may reflect the need to re-enter the cell cycle to activate DNA repair . We show that cyclin-C-directed , pRb-dependent G(0) exit activates the non-homologous end joining pathway of DNA repair ( NHEJ ) in postmitotic neurons . Using RNA interference , we found that abrogation of cyclin-C-mediated exit from G(0) compromised DNA repair but did not initiate apoptosis . Forced G(1) entry combined with prevention of G(1) --&gt ; S progression triggered NHEJ activation even in the absence of DNA lesions , but did not induce apoptosis in contrast to unrestricted progression through G(1) --&gt ; S. We conclude that G(0) --&gt ; G(1) transition is functionally significant for NHEJ repair in postmitotic neurons . These findings reveal the importance of cell-cycle activation for controlling both DNA repair and apoptosis in postmitotic neurons , and underline the particular role of G(1) --&gt ; S progression in apoptotic signaling , providing new insights into the mechanisms of DNA damage response ( DDR ) in postmitotic neurons .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

The present study was undertaken to explore protective effect of silymarin , a flavonolignan from milk thistle ( Silybum marianum ) , against Fe-NTA mediated renal oxidative stress , inflammation and tumor promotion response along with elucidation of the implicated mechanism(s) . Administration of Fe-NTA ( 10 mg/kg bd wt , i.p. ) to Swiss albino mice induced marked oxidative stress in kidney , evident from augmentation in renal metallothionein ( MT ) expression , depletion of glutathione content and activities of antioxidant and phase II metabolizing enzymes , and enhancement in production of aldehyde products such as 4-hydroxy-2-nonenal . Fe-NTA also significantly activated nuclear factor kappa B ( NFkappaB ) and upregulated the expression of downstream genes : cyclooxygenase 2 and inducible nitric oxide synthase and enhancing the production of proinflammatory cytokines : tumor necrosis factor alpha ( TNF-alpha ) and interleukin-6 ( IL-6 ) . However , feeding of 0.5% and 1% silymarin diet conferred a significant protection against Fe-NTA induced oxidative stress and inflammation . It further augmented MT expression , restored the antioxidant armory , ameliorated NFkappaB activation and decreased the expression of proinflammatory mediators . Silymarin also suppressed Fe-NTA induced hyperproliferation in kidney , ameliorating renal ornithine decarboxylase activity and DNA synthesis .

Both ATX and LPA have been shown to be involved in many cancers . However , the functional role of ATX and the regulation of ATX expression in human hepatocellular carcinoma ( HCC ) remain elusive . RESULTS In this study , ATX expression was evaluated in tissues from 38 human HCC and 10 normal control subjects . ATX was detected mainly in tumor cells within tissue sections and its over-expression in HCC was specifically correlated with inflammation and liver cirrhosis . In addition , ATX expression was examined in normal human hepatocytes and liver cancer cell lines . Hepatoma Hep3B and Huh7 cells displayed stronger ATX expression than hepatoblastoma HepG2 cells and normal hepatocytes did . Proinflammtory cytokine tumor necrosis factor alpha ( TNF-alpha ) promoted ATX expression and secretion selectively in Hep3B and Huh7 cells , which led to a corresponding increase in lysophospholipase-D activity . Moreover , we explored the mechanism governing the expression of ATX in hepatoma cells and established a critical role of nuclear factor-kappa B ( NF-kappaB ) in basal and TNF-alpha induced ATX expression . Further study showed that secreted enzymatically active ATX stimulated Hep3B cell invasion . CONCLUSIONS This report highlights for the first time the clinical and biological evidence for the involvement of ATX in human HCC . Our observation that links the TNF-alpha/NF-kappaB axis and the ATX-LPA signaling pathway suggests that ATX is likely playing an important role in inflammation related liver tumorigenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;activating invasion and metastasis" } ]

The cytotoxicity of cisplatin is mainly mediated through the formation of DNA adducts , which are also believed to be responsible for the secondary malignancies produced by the drug . The aim of this study was to determine the in vivo mutagenic activity of cisplatin in the lacZ plasmid-based transgenic mouse model . The mutant frequency ( MF ) and the spectrum of mutations induced by cisplatin in the mouse liver were analyzed and compared to controls . The mean MF in the lacZ gene was increased 2-fold in mice treated with a single 6 mg/kg body weight dose of cisplatin and sacrificed after 17 and 28 days ( P = 0.001 and P &lt ; 0.0001 ) . Restriction analysis and sequencing of mutant DNA showed that cisplatin was able to induce both large deletions and point mutations . A specific profile of base substitution and frameshift mutations was identified in treated mice , consisting primarily of G:C-->A:T transitions at GpG and ApG sites , the preferential DNA binding sites of cisplatin , and single basepair deletions/insertions . The present results provide the first evidence that cisplatin has mutagenic activity in vivo and induces a characteristic pattern of mutations in the mouse liver . This mutagenicity may be responsible for its tumorigenic activity .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

However , the molecular mechanisms underlying these antineoplastic effects are not well understood . We described previously that expression levels of the chemokine receptor , CCR5 , and the beta2-integrin , Mac-1 , were down-regulated on primary monocytes after incubation in supernatants from human carcinoma cell lines , and that this down-regulation resulted in impaired monocyte function with respect to migration and adhesion . We now demonstrate that these impairments are also present in vivo . Monocytes from cancer patients displayed significantly reduced CCR5 levels and migration capacities in comparison to cells from healthy donors . Because migration is necessary for the antitumor activity of monocytes/macrophages , these deficits may contribute to the suppressed immune system seen in cancer patients . In a clinical study , we analyzed the effect of a selective COX-2 inhibitor , Rofecoxib , on the migration of monocytes derived from cancer patients . The results revealed significant improvement in migration equal to those levels seen in healthy donors . We conclude that in patients with cancer , the intake of Rofecoxib for 3 wk leads to significant restoration of monocyte function . These data may , at least in part , help explain the anticancer effects of NSAIDs .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

( L.E.M. ethanol precipitate ; LEP ) on HepG2 human hepatocellular carcinoma ( HCC ) cells were investigated . LEP directly killed the HepG2 cells efficaciously , but had only minor effects on normal rat hepatocytes and normal mouse dermal cells under the same conditions . Characteristic morphological changes associated with apoptosis such as shrinkage , rounding , and floating as well as chromatin condensation were confirmed ; terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling ( TUNEL ) staining was positive as determined by fluorescence microscopy analyses . The caspase-3 and -8 death receptor pathway was found largely responsible for the apoptotic death of HepG2 cells treated with LEP .

The objective of the present study was to determine the frequency of lymphatic metastases and to study the pattern of lymph node metastasis in a large study population . METHODS The data from 1361 patients with thoracic esophageal squamous cell carcinoma who underwent curative R0 esophagectomy were retrospectively examined . Logistic regression analysis was used to identify the factors associated with lymph node metastasis . RESULTS Of the 1361 patients , 714 ( 52.5% ) were found to have lymph node metastasis . The frequency of lymph node metastasis increased as the tumor invasion increased . Paratracheal nodes were the most frequent metastasis nodes ( 15.9% ) . The frequency of lymph node metastasis was 9.8% in the neck , 18.0% in the upper mediastinum , 18.9% in the middle mediastinum , 11.8% in the lower mediastinum , and 28.4% in the abdomen . Of these 714 patients , 424 ( 31.2% ) presented with 1 field involvement , 255 ( 18.7% ) with 2 fields , and 35 ( 2.6% ) with 3 fields involvement . Logistic regression analysis revealed tumor length ( P<.001 ) , tumor invasion ( P<.001 ) , tumor differentiation ( P=.003 ) , and lymphovascular invasion ( P<.001 ) were risk factors for lymph node metastasis . Tumor location ( P<.001 ) , tumor invasion ( P=.003 ) , lymphovascular invasion ( P=.004 ) , and paratracheal lymph node involvement ( P=.002 ) were identified as risk factors for cervical lymph node metastasis . CONCLUSIONS Metastases were more frequent in the abdomen than in the neck . Total mediastinal and upper abdominal lymphadenectomy should be carefully conducted . Certain factors , such as tumor location , depth of tumor invasion , lymphovascular invasion , and paratracheal lymph node involvement , might be helpful in determining the need to perform cervical lymphadenectomy in individual patients .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

Coexpression of the growth factor and receptor suggests their role in autocrine or paracrine growth mechanisms . It has been reported previously that STI571 has specific activity in inhibiting select tyrosine kinase receptors , including PDGF and c-Kit . Osteosarcomas express low levels of c-Kit but abundant levels of PDGF receptor ( PDGFR ) . EXPERIMENTAL DESIGN To investigate the potential of STI571 as therapy for osteosarcoma , we studied its effects on PDGF-mediated cell growth in vitro and in an in vivo mouse model . RESULTS PDGF acted as a potent mitogen in a dose-dependent manner in two osteosarcoma cell lines . STI571 ( 1.0 micro M ) inhibited both PDGFR-alpha and PDGFR-beta phosphorylation and the downstream phosphorylation targets extracellular signal-regulated kinase and Akt . STI571 also inhibited PDGF-mediated growth and induced apoptosis in vitro as determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and terminal deoxynucleotidyl transferase-mediated nick end labeling staining . To study the effect of STI571 alone or in combination with Taxol in an in vivo model , an osteosarcoma cell line ( KRIB ) was transplanted into the tibia of athymic nude mice . Mice were treated with STI571 ( 50 mg/kg p.o. q M-F ) , Taxol ( 8 mg/kg i.p. weekly ) , or STI571 plus Taxol for 6 weeks . There was no significant difference in tumor size between treatment and control mice . Aberrant signaling pathways downstream of the PDGFR in the v-Ki-ras oncogene-transformed KRIB cell line may in part explain this finding . CONCLUSIONS Our data demonstrate that STI571 inhibits PDGF-mediated growth and leads to apoptosis of osteosarcoma cells in vitro by selective inhibition of the PDGFR tyrosine kinase . The effectiveness of STI571 in our studies suggests targeting of PDGFRs as a novel treatment for osteosarcoma .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

MHC-I and-II , ICAM-1 ( CD54 ) , NCAM ( CD56 ) , and Thy-1 ( CDw90 ) immunoreactivity was studied in eight primary Rb biopsy specimens using immunohistochemistry , three using immunoelectron microscopy , and six Rb cell lines using flow cytometry ( FCM ) . Parenchymal and vascular-associated cells , phenotypically similar to retinal microglia , strongly expressed MHC-II immunoreactivity and were distributed throughout primary Rb specimens . However , MHC-II expression on Rb cell lines was similar to nonspecific control levels . Tumor cells in primary Rb specimens displayed high NCAM , moderate Thy-1 , and low MHC-I and ICAM-1 immunolabeling . Tumor vasculature expressed low to moderate MHC-I and ICAM-1 immunoreactivity and moderate Thy-1 immunoreactivity . NCAM was not detected on the vasculature of primary Rb specimens . Rb cell lines displayed variable expression of Thy-1 , ICAM-1 , and MHC-I . NCAM was highly expressed on five of six Rb cell lines . The high levels of constitutive NCAM immunoreactivity on Rb tumor cells confirm the neuroectodermal origins of this tumor .

The ZEB1 transcriptional repressor promotes metastasis through downregulation of microRNAs ( miRs ) that are strong inducers of epithelial differentiation and inhibitors of stem cell factors . Given that each miR can target multiple genes with diverse functions , we posited that the prometastatic network controlled by ZEB1 extends beyond these processes . We tested this hypothesis using a mouse model of human lung adenocarcinoma metastasis driven by ZEB1 , human lung carcinoma cells , and human breast carcinoma cells . Transcriptional profiling studies revealed that ZEB1 controls the expression of numerous oncogenic and tumor-suppressive miRs , including miR-34a . Ectopic expression of miR-34a decreased tumor cell invasion and metastasis , inhibited the formation of promigratory cytoskeletal structures , suppressed activation of the RHO GTPase family , and regulated a gene expression signature enriched in cytoskeletal functions and predictive of outcome in human lung adenocarcinomas . We identified several miR-34a target genes , including Arhgap1 , which encodes a RHO GTPase activating protein that was required for tumor cell invasion . These findings demonstrate that ZEB1 drives prometastatic actin cytoskeletal remodeling by downregulating miR-34a expression and provide a compelling rationale to develop miR-34a as a therapeutic agent in lung cancer patients .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

GH3 cells were grown at increasing densities in the presence or absence of antirat PRL ( polyclonal and monoclonal ) or nonspecific antibodies . Cell proliferation increased with increasing cell density , as did the concentration of PRL in the medium . Antirat PRL , but not control antibody , markedly inhibited but did not eliminate cell proliferation , and this effect was diminished with increasing PRL concentration in the medium . PRL receptors were demonstrated on 40-50% of the cells by indirect immunofluorescence using a specific antirat PRL receptor monoclonal antibody . Cell surface PRL was colocalized to the same 40-50% of the cells and copatched or cocapped along with the receptors . Absence or presence of PRL receptors did not correlate with stage of the cell cycle , as judged by ethidium bromide dual labeling . Cell surface PRL was found to be on PRL-containing cells . These data have fulfilled four criteria necessary for establishment of a substance as a secreted autocrine growth factor : 1 ) the factor must be secreted ; 2 ) in log growth phase , increased cell proliferation should occur at increased cell densities ; 3 ) the cells must display a receptor for the factor ; and 4 ) there must be a growth response to the factor . Thus we have established that PRL is an autocrine growth factor for at least 40-50% of the GH3 cell population .

In some cases , the later aberrations have been reported to be reversible telomeric associations . We report here aberration and chromosome number studies of twenty-nine T antigen positive lineages , studied from their initiation by transfection of T antigen sequences into human diploid fibroblasts , until crisis or immortalization occurred or , in some cases until the lines became tumorigenic in nude mice . The data show that T antigen consistently produced chromosomal instability of both number and structure by an active process that began before transformation indicators were positive and continued throughout neoplastic progression . The most frequently observed aberrations were dicentric chromosomes , which were shown to be true dicentrics by examination by in situ hybridization with telomeric sequences . These data are consistent with the hypothesis that T antigen causes human fibroblasts to become neoplastically transformed by successive rounds of chromosomal mutation and lineage evolution .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;genomic instability and mutation" } ]

Therefore , there remains an urgent and unmet clinical need for the development of predictive biomarkers for trastuzumab response . Recently , several lines of evidence have demonstrated that the inflammatory tumor microenvironment is a major contributor to therapy resistance in breast cancer . In order to explore the predictive value of inflammation in breast cancer patients , we measured the inflammatory biomarkers serum ferritin and C-reactive protein ( CRP ) in 66 patients immediately before undergoing trastuzumab-containing therapy and evaluated their progression-free and overall survival . The elevation in pre-treatment serum ferritin ( >250 ng/ml ) or CRP ( >7.25 mg/l ) was a significant predictor of reduced progression-free survival and shorter overall survival . When patients were stratified based on their serum ferritin and CRP levels , patients with elevation in both inflammatory biomarkers had a markedly poorer response to trastuzumab-containing therapy . Therefore , the elevation in inflammatory serum biomarkers may reflect a pathological state that decreases the clinical efficacy of this therapy . Anti-inflammatory drugs and life-style changes to decrease inflammation in cancer patients should be explored as possible strategies to sensitize patients to anti-cancer therapeutics .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

Innate immunity and inflammation may increase the risk of prostate cancer . To determine the role of innate immunity and inflammation in advanced prostate cancer , we investigated the association of 320 single nucleotide polymorphisms , located in 46 genes involved in this pathway , with disease risk using 494 cases with advanced disease and 536 controls from Cleveland , Ohio . Taken together , the whole pathway was associated with advanced prostate cancer risk ( P = 0.02 ) . Two sub-pathways ( intracellular antiviral molecules and extracellular pattern recognition ) and four genes in these sub-pathways ( TLR1 , TLR6 , OAS1 , and OAS2 ) were nominally associated with advanced prostate cancer risk and harbor several SNPs nominally associated with advanced prostate cancer risk . Our results suggest that the innate immunity and inflammation pathway may play a modest role in the etiology of advanced prostate cancer through multiple small effects .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

Multiple myeloma ( MM ) , an almost incurable disease , is the second most common blood cancer . Initial chemotherapeutic treatment could be successful ; however , resistance development urges the use of higher toxic doses accompanied by hematopoietic stem cell transplantation . The establishment of more effective treatments that can overcome or circumvent chemoresistance has become a priority . We recently demonstrated that venom extracted from Walterinnesia aegyptia ( WEV ) either alone or in combination with silica nanoparticles ( WEV+NPs ) mediated the growth arrest and apoptosis of prostate cancer cells . In the present study , we evaluated the impact of WEV alone and WEV+NP on proliferation and apoptosis of MM cells . Methods . The impacts of WEV alone and WEV+NP were monitored in MM cells from 70 diagnosed patients . The influences of WEV and WEV+NP were assessed with flow cytometry analysis . Results . WEV alone and WEV+NP decreased the viability of MM cells . Using a CFSE proliferation assay , we found that WEV+NP strongly inhibited MM cell proliferation . Furthermore , analysis of the cell cycle using the propidium iodide ( PI ) staining method indicated that WEV+NP strongly altered the cell cycle of MM cells and enhanced the induction of apoptosis . Conclusions . Our data reveal the biological effects of WEV and WEV+NP on MM cells that enable these compounds to function as effective treatments for MM .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

It is an endocrine disruptor with a variety of other effects , including genotoxicity . Oxidative metabolism of bisphenol A yields electophilic bisphenol A-3,4-quinone ( BPAQ ) , which may cause genotoxicity . To determine the genotoxic potential of bisphenol A , the mechanism of the reaction between the BPAQ and deoxyadenosine ( dA ) was studied in detail . The most probable reaction pathway was determined using quantum chemical methods . Our results demonstrate that the rate limiting step is Michael addition between BPAQ and dA , the main product being the unstable N7-modified adduct that rapidly undergoes depurination . In addition , our calculations provide strong evidence for protonation of the adducts prior to depurination , which indicates pH dependence of the reaction . The calculated activation barrier for Michael addition is 28.7 kcal/mol , indicating that the reaction with dA is very slow . Comparison with the activation energy of 23.1 kcal/mol for the corresponding deoxyguanosine reaction indicates that most of the DNA damage by BPAQ will occur at the guanine site . The detoxification reactions with glutathione compete with reactions between BPAQ and DNA . The calculated free energy of activation for the reaction with glutathione is significantly lower than that for the corresponding reaction with dA . This indicates that BPAQ will preferably react with glutathione and will only react with DNA when the level of glutathione in the cell is low .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Although the mechanisms of RAD-51-DNA filament assembly and strand exchange are well characterized , the subsequent steps of HR are less well defined . Here , we describe a synthetic lethal interaction between the C. elegans helicase helq-1 and RAD-51 paralog rfs-1 , which results in a block to meiotic DSB repair after strand invasion . Whereas RAD-51-ssDNA filaments assemble at meiotic DSBs with normal kinetics in helq-1 , rfs-1 double mutants , persistence of RAD-51 foci and genetic interactions with rtel-1 suggest a failure to disassemble RAD-51 from strand invasion intermediates . Indeed , purified HELQ-1 and RFS-1 independently bind to and promote the disassembly of RAD-51 from double-stranded , but not single-stranded , DNA filaments via distinct mechanisms in vitro . These results indicate that two compensating activities are required to promote postsynaptic RAD-51 filament disassembly , which are collectively essential for completion of meiotic DSB repair .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

According to the mutation hypothesis immortalization is hardly to be expected under these conditions . However , immortalization was frequently observed . Therefore the induction of immortalization appears indirect . The progeny of benzo(a)pyrene treated cells immortalized with a rate of 3.9 x 10(-8)/cell/generation , which is 64 times higher than the spontaneous rate . The results are in line with the probabilistic theory developed in 1980 by both Fernandez et al . ( Proc . Natl . Acad . Sci . USA , 77 : 7272-7276 , 1980 ) and Kennedy et al . ( Proc . Natl . Acad .

Such mice showed a robust proliferative response in the skin , but did not manifest evidence of dysplasia or neoplasia .

BMR is distinguished by its adaptations to life underground , remarkable longevity ( with a maximum documented lifespan of 21 y ) , and resistance to cancer . Spontaneous tumors have never been observed in spalacids . To understand the mechanisms responsible for this resistance , we examined the growth of BMR fibroblasts in vitro of the species Spalax judaei and Spalax golani . BMR cells proliferated actively for 7-20 population doublings , after which the cells began secreting IFN-β , and the cultures underwent massive necrotic cell death within 3 d . The necrotic cell death phenomenon was independent of culture conditions or telomere shortening . Interestingly , this cell behavior was distinct from that observed in another long-lived and cancer-resistant African mole rat , Heterocephalus glaber , the naked mole rat in which cells display hypersensitivity to contact inhibition . Sequestration of p53 and Rb proteins using SV40 large T antigen completely rescued necrotic cell death . Our results suggest that cancer resistance of BMR is conferred by massive necrotic response to overproliferation mediated by p53 and Rb pathways , and triggered by the release of IFN-β . Thus , we have identified a unique mechanism that contributes to cancer resistance of this subterranean mammal extremely adapted to life underground .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;enabling replicative immortality;evading growth suppressors" } ]

However , the significance of ANXA2 expression in gastric carcinoma has not been clarified.To elucidate its roles in growth of gastric cancer , ANXA2 expression in SGC-7901 cells was inhibited with a designated siRNA , then cell proliferation , cell cycling , apoptosis and motility were determined by MTT assay , flow cytometry , Hoechst 33342 staining and wound healing assay , respectively . To further assess the behavior of ANXA2 deleted SGC- 7901 cells , changes of microstructures were observed under fluorescence microscopy , laser scanning confocal microscopy and electron microscopy . We found that inhibition of ANXA2 expression caused cell proliferation to decrease significantly with G1 arrest , motility to be reduced with changes in pseudopodia/filopodia structure and F-actin and β-tubulin expression , and apoptosis to be enhanced albeit without significance . At the same time , ANXA2 deletion resulted in fewer pseudopodia/filopodia , non-stained areas were increased , contact inhibition among cells reappeared , and expression of F-actin and β-tubulin was decreased , with induction of polymerized disassembled forms .

While treatment with selective BRAF(V600E) inhibitors ( like vemurafenib or dabrafenib ) leads to high response rates but short response duration , CTLA-4 blocking therapies induce sustained responses , but only in a limited number of patients . The combination of these diametric treatment approaches may further improve survival , but pre-clinical data concerning this approach is limited . We investigated , using Tyr::CreER(T2)PTEN(F-/-)BRAF(F-V600E/+) inducible melanoma mice , whether BRAF(V600E) inhibition can synergize with anti-CTLA-4 mAb treatment , focusing on the interaction between the BRAF(V600E) inhibitor PLX4720 and the immune system . While PLX4720 treatment strongly decreased tumor growth , it did not induce cell death in BRAF(V600E)/PTEN(-/-) melanomas . More strikingly , PLX4720 treatment led to a decreased frequency of tumor-resident T cells , NK-cells , MDSCs and macrophages , which could not be restored by the addition of anti-CTLA-4 mAb . As this effect was not observed upon treatment of BRAF wild-type B16F10 tumors , we conclude that the decreased frequency of immune cells correlates to BRAF(V600E) inhibition in tumor cells and is not due to an off-target effect of PLX4720 on immune cells . Furthermore , anti-CTLA-4 mAb treatment of inducible melanoma mice treated with PLX4720 did not result in enhanced tumor control , while anti-CTLA-4 mAb treatment did improve the effect of tumor-vaccination in B16F10-inoculated mice . Our data suggest that vemurafenib may negatively affect the immune activity within the tumor .

One of the most efficient subpopulations of cytotoxic cells in the destruction of tumors are NK cells . NK cells are activated and increase their cytotoxic potential and modulate their cytokine production after treatment with IFNgamma , IL-12 , TNFalpha and IL-2 . The investigation of the activity of NK cells was performed on peripheral blood lymphocytes ( PBL ) of 16 healthy controls and of 40 patients with metastatic breast carcinoma . Modulation of NK cells was performed with IL-2 , IL-7 , IL-12 , TNFalpha , monoclonal antibodies ( mAb ) for TNFalpha and TNFalpha receptors type I and II , as well as with sera of healthy controls and patients with breast cancer in different clinical stages . Modulating effect of the applied factors after in vitro treatment of PBL was evaluated by the cytotoxic assay using 51chromium . Our results indicate that IL-2 significantly increased the activity of NK cells of controls and breast cancer patients . The sera of patients with advanced breast cancer significantly reduced NK cell activity . IL-7 , IL-12 and mAb for TNFalpha do not significantly change the activity of NK cells . The presence of anti-TNFalpha mAb did not change the inhibitory effect of the sera of breast cancer patients with advanced disease on the activity of NK cells of controls and patients with breast cancer . Blocking of TNFalpha Rcs with mAbs decrease the reactivity of NK cells for IL-2 . The treatment of breast cancer patients with advanced clinical stage of breast cancer with IL-2 , as an additional therapy , could be advantageous , as NK cells after this treatment increase their cytotoxic activity against tumor cells and can improve therapeutical results .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

Acquisition of anti-apoptotic properties by cancer cells is important for metastasis , and recent studies suggest that transforming growth factor ( TGF)-β promotes the survival of certain types of cancer cells . Here , we found that in highly metastatic breast cancer cells , JygMC(A) , JygMC(B) and 4T1 , TGF-β ligands were produced in autocrine fashion . Pharmacological inhibition of endogenous TGF-β signalling by a TGF-β type I receptor kinase inhibitor in serum-free conditions increased the expression of BH3-only protein , Bim ( also known as Bcl2-like 11 ) in JygMC(A) and JygMC(B) cells , and caused apoptotic cell death . We also found that induction of Bim by TGF-β was not observed in Foxc1 knocked-down cancer cells . These findings suggest that TGF-β plays a crucial role in the regulation of survival of certain types of cancer cells through the TGF-β-Foxc1-Bim pathway , and that specific inhibitors of TGF-β signalling might be useful as apoptosis inducers in breast cancer cells .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

Overexpression of cyclin D1 was detected in 60% ( 263/440 ) and amplification of cyclin D1 was noted in 27% ( 119/440 ) of the primary breast carcinomas . Molecular analysis demonstrated that cyclin D1 was amplified in 30% ( 7/23 ) of the comedo DCIS , 22% ( 9/41 ) of the comedo DCIS and 32% ( 13/41 ) of the adjacent invasive ductal carcinomas , 30% ( 82/270 ) of the invasive ductal carcinomas , 27% ( 9/33 ) of the invasive lobular carcinomas , 19% ( 4/21 ) of the colloid carcinomas and 13% ( 2/15 ) of the medullary carcinomas . Cyclin D1 was amplified in 11% ( 2/19 ) of the invasive ductal carcinomas but not in the adjacent non-comedo DCIS lesions . Our observation showed that cyclin D1 was strongly positive in 61% ( 14/23 ) of the comedo subtype , 61% ( 11/18 ) of the non-comedo subtype , 59% ( 24/41 ) of the comedo DCIS and 63% ( 26/41 ) of the adjacent invasive ductal carcinomas , 53% ( 10/19 ) of the non-comedo DCIS and 58% ( 11/19 ) of the adjacent invasive lesions , 58% ( 157/270 ) of the invasive ductal carcinomas , 73% ( 24/33 ) of the invasive lobular carcinomas , 52% ( 11/21 ) of the colloid carcinomas and 27% ( 4/15 ) of the medullary carcinomas . A significant association was observed between in situ components and adjacent invasive lesions for cyclin D1 expression ( p<0.05 ) and amplification ( p<0.05 ) . A significant relationship was noted between amplification of cyclin D1 and lymph node metastases ( p<0.05 ) but not with histological grade ( p>0.05 ) , estrogen receptor status ( p>0.05 ) and proliferation index ( Ki-67 and PCNA ) ( p>0.05 ) . However , overexpression of cyclin D1 was statistically associated with well differentiated tumors ( p<0.05 ) and estrogen receptor positivity ( p<0.05 ) . No relationship was seen with nodal status ( p>0.05 ) and proliferation index ( Ki-67 and PCNA ) ( p>0.05 ) . These observations suggest that tumors positive for cyclin D1 protein may have features of good prognosis but amplification of cyclin D1 gene could be an indicator of tumors with poor prognostic features . Although majority of the Malaysian patients belong to younger age group ( <50 years old ) , amplification and expression of cyclin D1 was not statistically associated with patient age ( p>0.05 ) . These observations indicate that amplification and up-regulation of cyclin D1 may be independent of patient age . Moreover , overexpression and amplification of cyclin D1 in preinvasive , preinvasive and adjacent invasive lesions , and invasive carcinomas suggest that the gene may play an important role in early and late stages of breast carcinogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;activating invasion and metastasis" } ]

Mortality due to metastatic melanoma , one of the most aggressive and deadly cancers , has increased steadily over the last several decades . Unfortunately , the arsenal of chemotherapeutic agents available today is most often unsuccessful at extending and improving the life expectancy of afflicted individuals . We sought to identify an effective and nontoxic agent against metastatic melanoma . METHODOLOGY/PRINCIPAL FINDINGS We chose to study Cloudman S-91 mouse melanoma cells ( sub-clone M3 , CCL53.1 ) because these cells are highly aggressive and metastatic , representing one of the deadliest types of cancer . Melanoma cells also had an experimental advantage because their morphology , which is easily monitored , relates to the physiology of metastatic cells and normal melanocytes . We chose to test methyl sulfone as a chemotherapeutic agent for two reasons . Because of its chemical structure , we speculated a potential anti-cancer activity by targeting microtubules . Equally important , methyl sulfone has a well-established safety profile in humans . Surprisingly , we found that malignant melanoma cells exposed to methyl sulfone demonstrated the loss of phenotypes characteristic of malignant cells , and the reemergence of phenotypes characteristic of healthy melanocytes . Briefly , over time methyl sulfone induced contact inhibition , loss of ability to migrate through an extracellular matrix , loss of anchorage-independent growth , proper wound healing followed by contact inhibition , irreversible senescence followed by arborization with melanosomes in arbors as seen in normal melanocytes . CONCLUSIONS/SIGNIFICANCE Methyl sulfone may have clinical potential as a non-toxic agent effective against metastatic melanoma . Additionally , methyl sulfone has promise as a tool to explore molecular mechanisms of metastatic transformation as well as fundamental processes such as cell migration , contact inhibition , wound healing and cellular senescence .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;evading growth suppressors;activating invasion and metastasis" } ]

Evidence suggests that these aggressive cancer cells , often termed \" cancer stem cells \" or \" cancer stem-like cells \" ( CSCs ) , rely upon developmental signaling pathways that are important for survival and expansion of normal stem cells . Here we report that , in analogy to embryonic mammary epithelial biology , estrogen signaling expands the pool of functional breast CSCs through a paracrine FGF/FGFR/Tbx3 signaling pathway . Estrogen or FGF9 pretreatment induced CSC properties of breast cancer cell lines and freshly isolated breast cancer cells , whereas cotreatment of cells with tamoxifen or a small molecule inhibitor of FGFR signaling was sufficient to prevent the estrogen-induced expansion of CSCs . Furthermore , reduction of FGFR or Tbx3 gene expression was able to abrogate tumorsphere formation , whereas ectopic Tbx3 expression increased tumor seeding potential by 100-fold . These findings demonstrate that breast CSCs are stimulated by estrogen through a signaling pathway that similarly controls normal mammary epithelial stem cell biology .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Slow progressor melanomas contained no activated T lymphocytes ( TL ) . In contrast , \" aggressive \" melanomas were infiltrated by activated TLs lacking effector molecules and expressing high levels of PD-1 , indicating an exhausted phenotype . Aggressive melanomas were also infiltrated by immature myeloid cells ( IMC ) . Infiltration was associated with local inflammation and systemic Th2/Th17-oriented chronic inflammation that seemed to impair further activation of TLs , as tumor-specific T cells adoptively transferred into mice bearing aggressive melanomas were poorly activated and failed to infiltrate the melanoma . This immunosuppression also led to the incapacity of these mice to reject inoculated TA-positive tumors , in contrast to slow-progressing melanoma-bearing mice , which were responsive . To test the role of adaptive immunity in tumor progression , we induced melanomas in immunodeficient RagKO compound mice . These mice developed aggressive but not slow-progressing melanomas at a higher frequency and with a shorter latency than immunocompetent mice . Immunodeficient mice also developed abnormal inflammation and infiltration of IMCs in a manner similar to immunocompetent mice , indicating that this phenotype was not dependent on adaptive immunity . Therefore , tumor-intrinsic factors distinguishing the two melanoma types control the initiation of inflammation , which was independent of adaptive immunity . The latter delayed development of aggressive melanomas but was overridden by inflammation .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;avoiding immune destruction" } ]

Resveratrol has also been shown to induce antiproliferation and apoptosis of several leukemia cell lines . In the present study , we investigated the effect of resveratrol in adult T cell leukemia . Our present observations showed that resveratrol induced growth inhibition in all five human T cell lymphotrophic virus-1-infected cell lines examined , with 50% effective dose of 10.4-85.6 mM . In the resveratrol-treated cells , induction of apoptosis was confirmed by annexin V-based analyses and morphological changes . The most surprising observation was that resveratrol treatment resulted in a gradual decrease in the expression of survivin , an antiapoptotic protein , during cell apoptosis . These findings indicate that resveratrol inhibits the growth of human T cell lymphotrophic virus-1-infected cell lines , at least in part , by inducing apoptosis mediated by downregulation in survivin expression . In view of the accumulating evidence that survivin may be an important determinant of a clinical response in adult T cell leukemia , our present findings have led to the suggestion that resveratrol , a common constituent of the human diet , merits further investigation as a potential therapeutic agent for this incurable disease .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

The toxins induced DNA degradation , and light and electron microscopical studies revealed that lysis was preceded by reorganization of intracellular vacuoles , cell blebbing , and chromatin condensation both in Vero and in MDCK cells . Cell lysis was efficiently inhibited by cycloheximide and 3-methyladenine ( 3MA ) , a specific inhibitor of autophagy . Cycloheximide , which like 3MA inhibits autophagy , protected even when added at a time when the protein synthesis had been blocked by ricin , suggesting that the effect of cycloheximide on cell lysis is independent of its ability to inhibit protein synthesis . Also theophylline and dibutyryl-cGMP had some protective effect , whereas a number of compounds reported to protect against apoptosis in other systems were without protective effects .

Therefore , new therapeutic approaches for renal cancer are essential . Englerin A is a natural product with a very potent and selective cytotoxicity against renal cancer cells . This makes it a promising drug candidate that may improve current treatment standards for patients with renal cancers in all stages . However , little is known about englerin A's mode of action in targeting specifically renal cancer cells . Our study is the first to investigate the biological mechanism of englerin A action in detail . We report that englerin A is specific for renal tumor cells and does not affect normal kidney cells . We find that englerin A treatment induces necrotic cell death in renal cancer cells but not in normal kidney cells . We further show that autophagic and pyroptotic proteins are unaffected by the compound and that necrotic signaling in these cells coincided with production of reactive oxygen species and calcium influx into the cytoplasm . As the first study to analyze the biological effects of englerin A , our work provides an important basis for the evaluation and validation of the compound's use as an anti-tumor drug .

Matrix metalloproteinase-9 ( MMP-9 ) , which degrades the extracellular matrix , is a major component in the process of cancer cell invasion . Sulfuretin is one of the major flavonoids isolated from Rhus verniciflua . Sulfuretin has been used to reduce oxidative stress , platelet aggregation , the inflammatory response and mutagenesis . However , the effect of sulfuretin on breast cancer metastasis is unknown . In this study , we investigated the inhibitory effect of sulfuretin on 12-O-tetradecanoylphorbol-13-acetate ( TPA)-induced MMP-9 expression and cell invasion in MCF-7 cells . Sulfuretin inhibited TPA-induced transcriptional activation of nuclear factor-κB ( NF-κB ) . We demonstrated that sulfuretin mediated the inhibition of TPA-induced MMP-9 expression and that cell invasion in MCF-7 cells involved suppression of the NF-κB pathway . Therefore , inhibiting MMP-9 expression by sulfuretin may have therapeutic potential for controlling breast cancer invasiveness .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

In the present study , we studied the metabolomic profiles using high analyte specific gas chromatography/mass spectrometry ( GC/MS ) and liquid chromatography tandem mass spectrometry ( LC/MS/MS ) to attain a systems-level view of the shift in metabolism in cells progressing along the path to CRC . Colonic tissues including tumor , polyps and adjacent matched normal mucosa from 26 patients with sporadic CRC from freshly isolated resections were used for this study . The metabolic profiles were obtained using GC/MS and LC/MS/MS . Our data suggest there was a distinct profile change of a wide range of metabolites from mucosa to tumor tissues . Various amino acids and lipids in the polyps and tumors were elevated , suggesting higher energy needs for increased cellular proliferation . In contrast , significant depletion of glucose and inositol in polyps revealed that glycolysis may be critical in early tumorigenesis . In addition , the accumulation of hypoxanthine and xanthine , and the decrease of uric acid concentration , suggest that the purine biosynthesis pathway could have been substituted by the salvage pathway in CRC . Further , there was a step-wise reduction of deoxycholic acid concentration from mucosa to tumors . It appears that to gain a growth advantage , cancer cells may adopt alternate metabolic pathways in tumorigenesis and this flexibility allows them to adapt and thrive in harsh environment .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

Rhabdoid tumor in the prostate has been described only once in the prostatic region as a possible epithelial origin . Rhabdoid features in prostatic stromal sarcomas ( PSSs ) have never been described in the literature . Here , we report a case of a PSS with rhabdoid features . A 31-year-old man presented with a 4-month history of voiding difficulty and anal pain . Computed tomography of the abdomen revealed an ovoid mass in the prostate invading rectum and urinary bladder . A needle biopsy was diagnosed as an unclassified spindle cell sarcoma , and 2 cycles of adriamycin-based neoadjuvant chemotherapy were given , followed by radical prostatectomy . The prostatectomy specimen revealed a high-grade sarcoma with fascicles of highly cellular spindle cells and numerous mitoses with hemorrhage and necrosis . In areas , the tumor also contained sheets of loosely cohesive epithelioid cells with rhabdoid tumor component . Both spindle and rhabdoid tumor cells were positive for vimentin , CD34 , and progesterone receptor and negative for desmin and cytokeratin immunostainings . The rhabdoid tumor cells retained INI1 expression . The tumor recurred in the bladder , and the patient died of sepsis . To the best of our knowledge , this is the first case of PSS with rhabdoid features .

HER2 probably plays a critical role in many types of cancer , including urothelial carcinoma of the bladder ( UCB ) . Stage T1 UCB exhibits heterogeneous clinical behaviour , and the frequency of HER2 expression in such disease has not been thoroughly examined . The aim of this study was to use an immunohistochemical technique to evaluate the frequency of HER2 expression in a defined population-based cohort of patients registered as having primary stage T1 UCB . MATERIAL AND METHODS The initial study population comprised 285 patients registered as having primary stage T1 UCB . The original histological specimens were re-evaluated with regard to T stage and World Health Organization grade . Hospital records provided information on tumour size , multiplicity , possible presence of histologically proven recurrence and progression . The patients were followed for at least 5 years or until death . In tumours still considered stage T1 after re-evaluation , HER2 was investigated by immunohistochemistry of paraffin-embedded material and scored according to the guidelines used in breast cancer . RESULTS After histopathological re-evaluation , 201 patients were still T1 UCB and could be investigated regarding HER2 expression . HER2 overexpression was observed in 25 of those patients ( 12.4% ) . HER2 status was not significantly associated with recurrence or progression . CONCLUSIONS HER2 was overexpressed in 12.4% of the present cohort of patients with primary stage T1 UCB . There was no significant association between tumour HER2 status and prognosis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

To combat this situation , lycopodine , a pharmacologically important bioactive component derived from Lycopodium clavatum spores , was tested against hormone sensitive ( LnCaP ) and refractory ( PC3 ) prostate cancer cells in vitro . This study aims to check if lycopodine has demonstrable anti-cancer effects and if it has , to find out the possible mechanism of its action . The MTT assay was performed to evaluate the cytotoxic effect . Depolarization of mitochondrial membrane potential , cell cycle , EGF receptor activity and apoptosis were recorded by FACS ; profiles of different anti- and pro-apoptotic genes and their products were studied by semi-quantitative RT-PCR , indirect-ELISA , western blotting . Drug-DNA interaction was determined by CD spectroscopy . Administration of lycopodine down-regulated the expression of 5-lipoxygenase and the 5-oxo-ETE receptor ( OXE receptor1 ) and EGF receptor , and caused up-regulation of cytochrome c with depolarization of mitochondrial inner membrane potential , without palpable change in p53 activity , resulting in apoptosis , cell arrest at G0/G1 stage and ultimately reduced proliferation of cancer cells ; concomitantly , there was externalization of phosphotidyl serine residues .

If these cells are mixed with an extract of basement-membrane proteins ( matrigel ) and injected s.c. , they form locally invasive and highly vascularized tumors .

When cultured in a gel of matrigel , they proliferated and formed branched and invasive colonies . In contrast , the parental NIH-3T3 cells cultured on matrigel remained as cell aggregates and were not invasive . I.V. injections of the tumor-derived NIH-3T3 cells produced many colonies on the surface of the lungs , whereas the parental NIH-3T3 cells were not metastatic . Zymographic analysis of the conditioned media obtained from both the tumor-derived and parental NIH-3T3 cells demonstrated higher amounts of the 72-kDa gelatinase ( type-IV collagenase ) enzyme in the tumor-derived cells . Also , tumor-derived NIH-3T3 cells , but not parental NIH-3T3 cells , secreted the 92-kDa type-IV collagenase .

PCH4 , a derivative of n-butylidenephthalide , has been investigated for its anti-tumor effects on oral squamous cell carcinoma ( OSCC ) . The aim of this study was to investigate the anti-tumor mechanism of a potential target gene , Nur77 , in OSCC cells , which can be induced by PCH4 treatment . Data show that PCH4 promoted Nur77 translocation from the nucleus to the cytoplasm and induced cell apoptosis in OSCC cells . When Nur77 translocation was blocked , the degree of tumor apoptosis caused by PCH4 was significantly inhibited ( p < 0.05 ) . Within the MAPK pathway , PCH4 only induced JNK phosphorylation . Furthermore , treatment with a JNK inhibitor significantly reduced PCH4-induced apoptosis ( p < 0.05 ) and decreased PCH4-induced Nur77 expression ( p < 0.05 ) . In a xenograft animal model , administration of PCH4 also showed anti-tumor effects . We have demonstrated that OSCC cells are sensitive to PCH4 and that Nur77 protein translocation from the nucleus to the cytoplasm might be associated with the induction of apoptosis by PCH4 .

The antitumor effect of imiquimod is multifactorial , although its ability to modulate immune responses by triggering TLR7/8 is thought to be key . Among the immune cells suggested to be involved are plasmacytoid DCs ( pDCs ) . However , a direct contribution of pDCs to tumor killing in vivo and the mechanism of their recruitment to imiquimod-treated sites have never been demonstrated . Using a mouse model of melanoma , we have now demonstrated that pDCs can directly clear tumors without the need for the adaptive immune system . Topical imiquimod treatment led to TLR7-dependent and IFN-α/β receptor 1-dependent ( IFNAR1-dependent ) upregulation of expression of the chemokine CCL2 in mast cells . This was essential to induce skin inflammation and for the recruitment of pDCs to the skin . The recruited pDCs were CD8α+ and induced tumor regression in a TLR7/MyD88- and IFNAR1-dependent manner . Lack of TLR7 and IFNAR1 or depletion of pDCs or CD8α+ cells from tumor-bearing mice completely abolished the effect of imiquimod . TLR7 was essential for imiquimod-stimulated pDCs to produce IFN-α/β , which led to TRAIL and granzyme B secretion by pDCs via IFNAR1 signaling . Blocking these cytolytic molecules impaired pDC-mediated tumor killing . Our results demonstrate that imiquimod treatment leads to CCL2-dependent recruitment of pDCs and their transformation into a subset of killer DCs able to directly eliminate tumor cells .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

CRPC remains dependent on androgen receptor ( AR ) signaling , which may include constitutive , ligand-independent action of naturally occurring AR splice variants . For example , the AR splice variant AR3 ( also termed AR-V7 ) is expressed in CRPC and is linked to poor prognosis . Vav3 , a Rho GTPase guanine nucleotide exchange factor , is an AR coactivator that is up-regulated in human prostate cancer compared with benign tissue and in preclinical models of CRPC . Vav3 confers castration-resistant growth to androgen-dependent human prostate cancer cells . Despite the importance of AR coactivators in promoting CRPC , the potential role of these regulatory proteins in modulating AR splice variant activity is unknown . We examined the contributions of Vav3 to AR activity in two CRPC cell lines that naturally express relatively high levels of Vav3 and AR3 . Vav3 or AR3 knockdown greatly attenuated cell proliferation , soft agar growth , and ligand-independent AR activity . Vav3 potently enhanced the transcriptional activity of AR3 and another clinically relevant AR splice variant , ARv567es . Vav3 knockdown resulted in lowered nuclear AR3 levels , whereas total AR3 levels remained similar . Conversely , overexpression of Vav3 resulted in increased nuclear AR3 . Coimmunoprecipitation revealed that AR3 and Vav3 interact . These novel data demonstrating physical and functional interactions between Vav3 , a unique AR coactivator , and an AR splice variant provide insights into the mechanisms by which Vav3 exploits and enhances AR signaling in the progression to CRPC .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

However , the high incidence of tumor recurrence and metastasis after liver surgery remains a major problem . Recent studies have shown that hepatic ischemia-reperfusion ( I/R ) injury and endothelial progenitor cells ( EPCs ) contribute to tumor growth and metastasis . We aim to investigate the mechanism of FTY720 , which was originally applied as an immunomodulator , on suppression of liver tumor metastasis after liver resection and partial hepatic I/R injury . METHODOLOGY/PRINCIPAL FINDINGS An orthotopic liver tumor model in Buffalo rat was established using the hepatocellular carcinoma cell line McA-RH7777 . Two weeks after orthotopic liver tumor implantation , the rats underwent liver resection for tumor-bearing lobe and partial hepatic I/R injury . FTY720 ( 2 mg/kg ) was administered through the inferior caval vein before and after I/R injury . Blood samples were taken at days 0 , 1 , 3 , 7 , 14 , 21 and 28 for detection of circulating EPCs ( CD133+CD34+ ) . Our results showed that intrahepatic and lung metastases were significantly inhibited together with less tumor angiogenesis by FTY720 treatment . The number of circulating EPCs was also significantly decreased by FTY720 treatment from day 7 to day 28 . Hepatic gene expressions of CXCL10 , VEGF , CXCR3 , CXCR4 induced by hepatic I/R injury were down-regulated in the treatment group . CONCLUSIONS/SIGNIFICANCE FTY720 suppressed liver tumor metastasis after liver resection marred by hepatic I/R injury in a rat liver tumor model by attenuating hepatic I/R injury and reducing circulating EPCs .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;inducing angiogenesis" } ]

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h . Real time PCR and flow cytometry analyses suggested that Nigella sativa extracts possess the ability to suppress the proliferation of human breast cancer cells through induction of apoptosis.\n OUTPUT: sustaining proliferative signaling;resisting cell death\n\n INPUT: Cancer vaccines based on human tumor-associated antigens ( TAA ) have been tested in patients with advanced or recurrent cancer , in combination with or following standard therapy . Their immunogenicity and therapeutic efficacy has been difficult to properly evaluate in that setting characterized by multiple highly suppressive effects of the tumor and the standard therapy on the patient's immune system . In animal models of human cancer , vaccines administered in the prophylactic setting are most immunogenic and effectively prevent cancer development and progression . We report results of a clinical study that show that in patients without cancer but with a history of premalignant lesions ( advanced colonic adenomas , precursors to colon cancer ) , a vaccine based on the TAA MUC1 was highly immunogenic in 17 of 39 ( 43.6% ) of vaccinated individuals , eliciting high levels of anti-MUC1 immunoglobulin G ( IgG ) and long-lasting immune memory . Lack of response in 22 of 39 individuals was correlated with high levels of circulating myeloid-derived suppressor cells ( MDSC ) prevaccination . Vaccine-elicited MUC1-specific immune response and immune memory were not associated with significant toxicity . Our study shows that vaccines based on human TAAs are immunogenic and safe and capable of eliciting long-term memory that is important for cancer prevention . We also show that in the premalignant setting , immunosuppressive environment ( e.g. , high levels of MDSC ) might already exist in some individuals , suggesting an even earlier premalignant stage or preselection of nonimmunosuppressed patients for prophylactic vaccination .

Several cancer-preventive mechanisms have been proposed , such as antioxidant properties and modulation of biotransformation enzyme activities ; both may be associated with reducing DNA damage and hence the mutation rate . We investigated , in a randomized , controlled , crossover feeding trial , the effect of 10 servings/day of botanically defined F&V for 2 wk on endogenous DNA damage ; resistance to gamma -irradiation damage ; and DNA repair capacity in lymphocytes , measured by the Comet assay . We also explored the association between the UGT1A1*28 polymorphism and serum bilirubin concentrations and DNA damage and repair measures . Healthy men ( n = 11 ) and women ( n = 17 ) , age 20 to 40 yr , provided blood samples at the end of each feeding period . Overall , F&V did not affect DNA damage and repair measures in lymphocytes . The number of UGT1A1*28 alleles was inversely associated with sensitivity to gamma -irradiation exposure and DNA repair capacity , but a biological mechanism to explain this association is unclear . A larger sample size is needed to investigate the association between bilirubin concentrations and endogenous DNA damage . With inconsistent findings in the literature , additional dietary intervention studies on the effect of F&V on DNA damage and repair are needed .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

In this study , this growth inhibitor was purified by affinity chromatography and identified as the heat shock cognate 70 protein ( hsc70 ) based on its peptide microsequencing and specific antibody recognition . Among intracellular proteins , including other heat shock proteins , only constitutive hsc70 was secreted in response to the high-cell density . Moreover , hsc70 secretion from cancer cells was generated by serum deprivation , whereas its cellular concentration did not change . Prevention of Hsc70 secretion by cath D overexpression was associated with the formation of multilayer cell cultures , thus indicating a loss of contact inhibition . In addition , we showed that supplementing the culture medium with purified hsc70 inhibited cell proliferation in the nanomolar range . Conversely , removal of this extracellular hsc70 from the medium by either retention on ADP-agarose or competition at the Hsc70 binding site restored cell proliferation . Hsc70 appears active in human breast cancer cells and hypersecreted by direct cath D inhibition . These results suggest a new role of this secreted hsc70 chaperone in cell proliferation that might account for the higher tumor growth of cancer cells overexpressing cath D .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]
