A germline mutation in one of the genes involved in the process may be responsible for a dominantly inherited cancer syndrome , hereditary nonpolyposis colon cancer . Cancer progression in predisposed individuals results from the somatic inactivation of the normal copy of the MMR gene , leading to a mutator phenotype affecting preferentially repeat sequences ( microsatellite instability , MSI ) . Recently , we identified children with a constitutional deficiency of MMR activity attributable to a mutation in the h MLH1 gene . These children exhibited a constitutional genetic instability associated with clinical features of de novo neurofibromatosis type 1 ( NF1 ) and early onset of extracolonic cancer . Based on these observations , we hypothesized that somatic NF1 gene mutation was a frequent and possibly early event in MMR-deficient cells . To test this hypothesis , we screened for NF1 mutations in cancer cells . Genetic alterations were identified in five out of ten tumor cell lines with MSI , whereas five MMR-proficient tumor cell lines expressed a wild-type NF1 gene . Somatic NF1 mutations were also detected in two primary tumors exhibiting an MSI phenotype . Finally , a 35-bp deletion in the murine Nf1 coding region was identified in mlh1-/- mouse embryonic fibroblasts . These observations demonstrate that the NF1 gene is a mutational target of MMR deficiency and suggest that its inactivation is an important step of the malignant progression of MMR-deficient cells .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

We have shown previously that a p.o.-active , long-acting butyrate analogue , sodium phenylbutyrate ( PB ) , reduced proliferation in normal and malignant human breast cells in culture and reduced expression of ovarian hormone receptors , suggesting that PB had cellular effects consistent with decreasing breast cancer risk . The aim of this study was to determine the in vivo effects of PB in the normal mammary gland on epithelial cell proliferation , estrogen receptor alpha ( ER alpha ) expression , and cyclin D1 expression . BALB/c mice were treated with PB , delivered by mini-osmotic pumps , for 7 days . Moderate ( 250 mg/kg/day ) and high ( 500 mg/kg/day ) PB treatment resulted in a decrease in proliferation in mammary epithelial cells ( P &lt ; 0.001 ) , determined by bromodeoxyuridine incorporation . Analysis of ER alpha immunostaining revealed a significant reduction in moderate- and high-treatment groups ( P = 0.01 and P = 0.02 ) , and expression of cyclin D1 was virtually ablated ( P &lt ; 0.001 ) . Histone deacetylase inhibition is a known mechanism of butyrate action , and consistent with this , PB increased levels of acetylated histone H3 in the mammary gland . In summary , PB decreased proliferation in the mammary gland in vivo at clinically achievable doses . Decreased proliferation was accompanied by changes in the levels of ER alpha and cyclin D1 . These data show that PB modulates parameters thought to be involved in the carcinogenic process in the normal mammary gland , and compounds in this class may therefore be useful candidates for breast cancer chemoprevention .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

We therefore investigated interstitial tumour illumination as a means of selective PDT . A piece of colon carcinoma CC531 was implanted in the liver of Wag/Rij rats . Photofrin was administered ( 5 mg kg-1 i.v. ) 2 days before laser illumination . Tumours with a mean ( +/- s.e. ) diameter of 5.7 +/- 0.1 mm ( n = 106 , 20 days after implantation ) were illuminated with 625 nm light , at 200 mW cm-1 from a 0.5 cm cylindrical diffuser and either 100 , 200 , 400 , 800 or 1600 J cm-1 . Control groups received either laser illumination only , Photofrin only or diffuser insertion only . Short-term effects were studied on the second day after illumination by light microscopy and computer-assisted integration of the circumference of damaged areas . Long-term effects were studied on day 36 . To determine the biochemistry of liver damage and function , serum ASAT and ALAT levels were measured on day 1 and 2 , and antipyrine clearance on day 1 . Tumour and surrounding liver necrosis increased with light dose delivered ( P &lt ; 0.001 ) . Best long-term results were obtained at 800 J cm-1 with complete tumour remission in 4 out of 6 animals . No deterioration in liver function was found . The results of this study show the ability of interstitial PDT to cause major destruction of tumour tissue in the liver combined with minimal liver damage .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

During most of the cell cycle , Tem1 activity is antagonized by a GTPase activating complex ( GAP ) composed of Bub2 and Bfa1 . Bfa1 protein has cell cycle regulated phosphorylation depending upon the Polo-like kinase Cdc5 . This phosphorylation dissociates Bfa1 from Tem1 and thus relieves the inhibition of Tem1 by the GAP complex . Bub2 and Bfa1 are also required to prevent mitotic exit when there is DNA damage , spindle damage or spindle misorientation at G(2)/M phase . While Cdc5 inhibits Bfa1/Bub2 , mutating the Cdc5 phosphorylation sites on Bfa1 does not have a strong activating effect on Bub2/Bfa1 , suggesting there must be additional regulation in this pathway . Here we report that Bub2 protein also has cell cycle regulated phosphorylation . This phosphorylation is partially dependent upon the Polo-like kinase Cdc5 and is consistent with negative regulation of the Bub2/Bfa1 GAP complex . Spindle damage or spindle misorientation prevents Bub2 phosphorylation . The spindle damage effect is dependent upon the spindle assembly checkpoint components Mad2 and Mps1 . Thus like Bfa1 , Bub2 protein is also controlled both during mitotic exit and in response to cell cycle checkpoints . Bub2 phosphorylation is likely to be controlled by a novel kinase .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors" } ]

Therefore , we tested the effects of chronic inorganic arsenic exposure on the normal estrogen receptor ( ER)-negative breast epithelial cell line , MCF-10A . Cells were chronically exposed to a low-level arsenite ( 500nM ) for up to 24weeks . Markers of cancer cell phenotype and the expression of critical genes relevant to breast cancer or stem cells ( SCs ) were examined . After 24weeks , chronic arsenic-exposed breast epithelial ( CABE ) cells showed increases in secreted MMP activity , colony formation , invasion , and proliferation rate , indicating an acquired cancer cell phenotype . These CABE cells presented with basal-like breast cancer characteristics , including ER-α , HER-2 , and progesterone receptor negativity , and overexpression of K5 and p63 . Putative CD44(+)/CD24(-/low) breast SCs were increased to 80% over control in CABE cells . CABE cells also formed multilayer cell mounds , indicative of loss of contact inhibition . These mounds showed high levels of K5 and p63 , indicating the potential presence of cancer stem cells ( CSCs ) . Epithelial-to-mesenchymal transition occurred during arsenic exposure . Overexpression of aromatase , a key rate-limiting enzyme in estrogen synthesis , occurred with arsenic starting early on in exposure . Levels of 17β-estradiol increased in CABE cells and their conditioned medium . The aromatase inhibitor letrozole abolished arsenic-induced increases in 17β-estradiol production and reversed cancer cell phenotype . Thus , chronic arsenic exposure drives human breast epithelia into a cancer cell phenotype with an apparent overabundance of putative CSCs . Arsenic appears to transform breast epithelia through overexpression of aromatase , thereby activating oncogenic processes independent of ER .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;sustaining proliferative signaling;evading growth suppressors" } ]

As in ovarian cancer cells , increased metabolic activity and glucose concentration has been linked to aggressiveness of cancer . However , it is unclear as to whether targeting the glycolytic pathway may kill the malignant cells and likely have broad therapeutic implications against ovarian cancer metastasis . In the present research , we found that EF24 , a HIF-1α inhibitor , could significantly block glucose uptake , the rate of glycolysis , and lactate production compared with vehicle treatment in SKOV-3 , A2780 and OVCAR-3 cells . These results might possibly contribute to the further observation that EF24 could inhibit ovarian cancer cell migration and invasion from wound healing and Transwell assays . Furthermore , as an important mediator of glucose metabolism , glucose transporter 1 ( Glut1 ) was found to contribute to the function of EF24 in both energy metabolism and metastasis . To examine the effect of EF24 and the mediated role of Glut1 in vivo in a xenograph subcutaneous tumor model , intraperitoneal metastasis and lung metastasis model were introduced . Our results indicated that EF24 treatment could inhibit tumor growth , intraperitoneal metastasis and lung metastasis of SKOV-3 cells , and Glut1 is a possible mediator for the role of EF24 . In conclusion , our results highlight that an anti-cancer reagent with an inhibiting effect on energy metabolism could inhibit metastasis , and EF24 is a possible candidate for anti-metastasis therapeutic applications for ovarian cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;activating invasion and metastasis" } ]

Increased expression of glycolytic enzymes is considered as one contributing factor . The role of mitochondrial defects in acquisition of glycolytic phenotypes has been postulated but remains controversial . Here we show that functional defects in mitochondrial respiration could be induced by oncogenic H-Ras(Q61L) transformation , even though the mitochondrial contents or mass was not reduced in the transformed cells . First , mitochondrial respiration , as measured by mitochondrial oxygen consumption , was suppressed in NIH-3T3 cells transformed with H-Ras(Q61L) . Second , oligomycin or rotenone did not reduce the cellular ATP levels in the H-Ras(Q61L) transformed cells , suggesting a diminished role of mitochondrial respiration in the cellular energy metabolism . Third , inhibition of glycolysis with iodoacetic acid reduced ATP levels at a much faster rate in H-Ras(Q61L) transformed cells than in the vector control cells . The reduction of cellular ATP levels was reversed by exogenously added pyruvate in the vector control cells but not in H-Ras(Q61L) transformed cells . Finally when compared to the HRas(Q61L) transformed cells , the vector control cells had increased resistance toward glucose deprivation . The increased resistance was dependent on mitochondrial oxidative phosphorylation since rotenone or oligomycin abolished the increased survival of the vector control cells under glucose deprivation . The results also suggest an inability of the H-Ras(Q61L) transformed cells to reactivate mitochondrial respiration under glucose deprivation . Taken together , the data suggest that mitochondrial respiration can be impaired during transformation of NIH-3T3 cells by oncogeneic H-Ras(Q61L) .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

To date , however , little is known about glucose metabolism in breast cancer tissue . METHODS We analysed 55 breast cancer specimens , 26 adjacent ductal carcinomas in situ ( DCIS ) and 23 adjacent normal breast tissues for expression of glycolytic markers by immunohistochemistry . RESULTS We found expression of pAkt in 49% , GLUT1 in 25% , M2PK in 68% and TKTL1 in 31% of the tumours investigated . Expression of pAkt and Her2neu are positively correlated with borderline significance ( P = 0.055 ) . Expression of pAkt , GLUT1 and TKTL1 were higher in breast cancer and DCIS than in normal tissue . Surprisingly , M2PK expression was highest in normal breast tissue .

For example , administration of the human epidermal growth factor receptor ( EGFR ) antibody , alone or in combination with a chemotherapeutic drug , is thought to primarily inhibit tumor cell proliferation . The aim of this study was to assess the effects of a combined blockade designed to inhibit tumor growth by inhibition of proliferation rate and the proinflammatory effects of interleukin ( IL ) 8 . EXPERIMENTAL DESIGN A human breast carcinoma cell line that produces high levels of IL-8 was injected s.c. into severe combined immunodeficient mice . IL-8 has been reported to augment the progression of some human tumors ; thus , we used a human IL-8 antibody , ABXIL8 , in combination with anti-EGFR , ABXEGFR , to inhibit the metastasis of MDA231 tumors . RESULTS Whereas anti-IL-8 alone had no appreciable antimetastatic effect , the combination of ABXIL8 significantly enhanced the antitumor effects of ABXEGFR , resulting in greater survival of SCID tumor-bearing mice . This effect on survival was correlated with decreased metastatic spread and decreased tumor size in mice receiving both antibodies . Intriguingly , in vitro studies indicate that this antibody combination markedly inhibited matrix metalloproteinase activity associated with MDA-231 cells to a greater degree than either antibody alone . CONCLUSION Combined administration of these two human antibodies using growth factor blockade in conjunction with chemokine blockade may thus provide a more effective approach for treatment of metastatic human breast carcinoma .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

The authors studied tumor progression and invasion from the perspective of angiogenesis and sought to understand the features of this type of tumor . METHODS Thirty-one specimens were resected from patients with neuroblastoma and the expression of vascular endothelial growth factor ( VEGF ) , and its receptor ( Flk-1 ) was examined using immunohistochemistry . The authors looked for correlations among the expressions of VEGF and its receptor with various clinicopathologic factors . In addition , they examined the expression and location of VEGF and Flk-1 mRNA in 10 primary neuroblastoma using in situ hybridization . RESULTS Both in situ hybridization and immunohistochemistry showed the presence of VEGF expression within the neuroblastoma cells . We found VEGF mRNA in neuroblastoma cells but not vascular endothelial cells according to in situ hybridization . Further , Flk-1 mRNA was present both in neuroblastoma cells and vascular endothelial cells . The level of VEGF expression was higher in unfavorable histology , using the criteria of Shimada , than in favorable histology .

We determined B lymphocytes IgA(+) and IgG(+) , as well as CD4(+) and CD8(+) T cells in the large intestine . We measured cellular apoptosis and the cytokines TNF-alpha , IFN-gamma and IL-10 . An increase in the number of IgA(+) ( P<0.01 ) was observed , but not in IgG(+) ( P<0.01 ) , or in the CD4(+) population ( P<0.01 ) in the mice treated with DMH and yoghurt . While in the group with the carcinogen there was an enhancement in the IgG(+) B cells ( P<0.01 ) and CD8(+) T cells ( P<0.01 ) . Yoghurt increased the number of apoptotic cells and induced IFN-gamma and TNF-alpha cytokine release , their production being regulated by an increase in IL-10 ( P<0.001 ) . We demonstrated that yoghurt may exert antitumour activity by a decrease in the inflammatory immune response mediated by IgA(+) increase , apoptosis induction and IL-10 release .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;resisting cell death" } ]

BACKGROUND Preclinical evidence that targeting the IGF-IR is effective in cancer treatment has been accumulating for almost 2 decades . Early clinical trials revealed an acceptable safety profile together with pharmacodynamic evidence that the receptor can be targeted successfully . It is premature to draw conclusions regarding the therapeutic potential of this class of compounds but well-documented single-agent activity was noted during phase I evaluations , and recent evidence from a phase-II study suggests that co-administration of an anti-IGF-1R antibody with chemotherapy for non-small-cell lung cancer ( NSCLC ) improves objective response rate and progression-free survival . VIEWPOINTS These early results are a strong indication for continued research on the targeting of IGF-R , particularly in the treatment of NSCLC . CONCLUSIONS Today , IGF-1R targeting appears a promising approach , more than two dozen compounds have been developed and clinical trials are underway .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

This has been proposed to explain the epidemiological association between higher consumption of fruits and vegetables , which are rich in antioxidants , and lower incidence of cancer . However , this remains to be demonstrated conclusively . The effects of carotenoid supplementation on 1 ) baseline DNA damage , 2 ) susceptibility of cellular DNA to oxidative attack , and 3 ) DNA repair were measured in the human lymphocyte cell line Molt-17 . Baseline DNA damage , susceptibility to oxidant attack ( 100 mumol/l H2O2 for 5 min at 4 degrees C ) , and disappearance of DNA single-strand breaks ( SSB ) after oxidative challenge were monitored by single-cell gel electrophoresis . DNA repair patch synthesis activity in cell extracts was determined using assays that measure nucleotide incorporation during repair of oxidative lesions in template DNA . Unlike single-cell gel electrophoresis , the parameters measured with these assays are not dependent on strand break religation . There was no evidence that beta-carotene , lutein , or beta-cryptoxanthin supplementation protected cellular DNA from oxidation under basal conditions or after oxidative challenge . However , only carotenoid-supplemented cells exhibited a significant decrease in numbers of SSB over a 2-h period after treatment with H2O2 . Carotenoid supplementation did not provoke any detectable change in repair patch synthesis activity . We conclude that supplementation with carotenoids at 8 mumol/l does not provide significant antioxidant protection for DNA in Molt-17 lymphocytes but may enhance recovery of cells from oxidative challenge , as measured by loss of SSB . We argue that these data are most consistent with carotenoids acting to enhance DNA strand break repair .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;tumor promoting inflammation" } ]

METHODS Neural cell death model was made by 4 mmol/L Al treated neuroblastoma cells ( SH-SY5Y ) . Cell viabilities were detected at different concentrations of Al and/or Nec-1 . Hoechst 33342/PI double staining was used to observe apoptosis and ( or ) necrosis that were quantified by flow cytometry using Annexin V/PI double staining . Apoptotic pathway was tested by activities of Caspase-3 , Caspase-8 and Caspase-9 . In addition , the expression of NF-kappa B and Cyt-c was measured by immunocytochemistry . RESULTS Cell viabilities were significantly decreased with the increasing concentrations of Al ( P &lt ; 0.05 ) , which could be significantly upregulated by 60 micromol/L Nec-1 ( P &lt ; 0.05 ) and were correlated with the concentrations of Nec-1 ( P &lt ; 0.05 , P &lt ; 0.01 ) . Apoptosis and necrosis were observed under fluorescent microscope and quantified by flow cytometry , which suggested an increasing trend of apoptotic and necrotic rates ( P &lt ; 0.05 , P &lt ; 0.01 ) . Whereas , Nec-1 could not only decrease the necrotic rate but also apoptotic rate as well ( P &lt ; 0.05 , P &lt ; 0.01 ) . Data of Nec-1 on caspases activities showed that Nec-1 could not affect Caspase-9 activity ( P &gt ; 0.05 ) and Cty-c protein expression as well ( P &gt ; 0.05 ) . However , Nec-1 could reduce Caspase-8 activity significantly ( P &lt ; 0.05 , P &lt ; 0.01 ) and increase NF-kappa B protein expression ( P &lt ; 0.05 , P &lt ; 0.01 ) and finally decrease Caspase-3 activity ( P &lt ; 0.05 ) .

METHODS AND STUDY DESIGN Alternating cycles of vincristine ( 1.5 mg/m2 ) , doxorubicin ( 80 mg/m2 ) and cyclophosfamide ( 1200 mg/m2 ) ( weeks 0 , 6 , 13 , 22 and 31 ) , ifosfamide ( 9 g/m2 ) , vincristine ( 1.5 mg/m2 ) , and actinomycin D ( 1.5 mg/m2 ) ( weeks 3 , 16 , 25 and 34 ) , and ifosfamide ( 9 g/m2 ) and etoposide ( 450 mg/m2 ) ( weeks 9 , 19 , 28 and 37 ) were administered . Primary chemotherapy-induced necrosis was graded : G3 ( complete necrosis ) , G2 ( microfoci of tumor cells ) and G1 ( macrofoci of tumor cells ) . RESULTS From 1996 to 1999 , 50 patients with Ewing sarcoma were enrolled . The median age was 23.5 years ( range , 4-56 ) . Chemotherapy-induced necrosis ( in 28 patients ) was G3 in 36% , G2 in 21% and G1 in 43% . At a median follow-up of 110 months ( range , 36-129 ) , 5-year overall survival and event-free survival were 72% and 66% , respectively . According to histologic response , 5-year event-free survival was 90% in G3 , 83% in G2 , and 42% in G1 ( P = 0.02 ) . In adult and pediatric ( <18 years ) patients , the incidence of G4 leukopenia was 62% and 74% , respectively , with febrile neutropenia in 13% and 21% , respectively . G4 thrombocytopenia occurred in 3% of cycles in adults and in 7% in pediatric patients . Platelet and red blood cell transfusions were required respectively in 1% and 11% of cycles in adults and in 6% and 24% of cycles in pediatric patients . CONCLUSIONS The six-drug combination can be administered safely in adult and pediatric populations . About 40% of patients have a poor chemotherapy-induced tumor necrosis , leading to poor probability of survival . New strategies are recommended to improve survival of poor responders to the six-drug combination .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

This metabolic reprogramming referred to as the Warburg effect is essential to the survival of tumor cells and provides them with substrates required for biomass generation . Molecular mechanisms responsible for this shift in glucose metabolism remain elusive . As described herein , we found that aberrant expression of the proinflammatory protein transglutaminase 2 ( TG2 ) is an important regulator of the Warburg effect in mammary epithelial cells . Mechanistically , TG2 regulated metabolic reprogramming by constitutively activating nuclear factor ( NF)-κB , which binds to the hypoxia-inducible factor ( HIF)-1α promoter and induces its expression even under normoxic conditions . TG2/NF-κB-induced increase in HIF-1α expression was associated with increased glucose uptake , increased lactate production and decreased oxygen consumption by mitochondria . Experimental suppression of TG2 attenuated HIF-1α expression and reversed downstream events in mammary epithelial cells . Moreover , downregulation of p65/RelA or HIF-1α expression in these cells restored normal glucose uptake , lactate production , mitochondrial respiration and glycolytic protein expression . Our results suggest that aberrant expression of TG2 is a master regulator of metabolic reprogramming and facilitates metabolic alterations in epithelial cells even under normoxic conditions . A TG2-induced shift in glucose metabolism helps breast cancer cells to survive under stressful conditions and promotes their metastatic competence .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;tumor promoting inflammation;activating invasion and metastasis" } ]

However , the underlying mechanisms are not well understood . Age-associated alterations in the DNA either due to oxidative damage , defects in DNA repair or epigenetic modifications such as methylation that lead to mutations and changes in the expression of genes are thought to be partially responsible . Here we report that epigenetic modifications in aged DNA also increase its immunogenicity rendering it more reactive to innate immune system cells such as the dendritic cells . We observed increased upregulation of costimulatory molecules as well as enhanced secretion of IFN-alpha from dendritic cells in response to DNA from aged donors as compared to DNA from young donors when it was delivered intracellularly via Lipofectamine . Investigations into the mechanisms revealed that DNA from aged subjects is not degraded , neither is it more damaged compared to DNA from young subjects . However , there is significantly decreased global level of methylation suggesting that age-associated hypomethylation of the DNA may be the cause of its increased immunogenicity . Increased immunogenicity of self DNA may thus be another mechanism that may contribute to the increase in age-associated chronic inflammation , autoimmunity and cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction;tumor promoting inflammation" } ]

EGF , a mitogen for breast cells , signals via EGFR/ErbB tyrosine kinase receptors which are implicated in breast cancer pathogenesis . Here we show paradoxically that EGF enhanced the OSM-induced inhibition of proliferation and induction of cellular differentiation in both estrogen receptor positive and negative breast cancer cells . This functional synergism was also seen with heregulin but not SCF , PDGF or IGF-1 , indicating that it was specific to EGF-related growth factors . Immunoprecipitation experiments revealed that gp130 was constitutively associated with ErbB-2 and ErbB-3 . There was a similar association between the OSMRbeta and ErbB-2 . Furthermore , EGF unexpectedly induced tyrosine phosphorylation of gp130 . We show that OSM induced phosphorylation of STAT3 . Both OSM and EGF activated the p42/44 MAP kinases , but while the MEK inhibitor , PD98059 , ablated the OSM-induced inhibition , it only partially ablated the inhibitory effects of OSM plus EGF . Thus , we have demonstrated that the receptors and signalling pathways of two apparently unrelated growth factors were intimately linked , resulting in an unexpected biological effect .

DNA damage was evaluated by high-performance liquid chromatography/electrospray ionization tandem mass spectrometry ( HPLC/ES-MS/MS ) , which measures r7,t8,t9-trihydroxy-c-10-(N ( 2)-deoxyguanosyl)-7,8,9,10-tetrahydrobenzo[a]pyrene ( BPdG ) , and a chemiluminescence immunoassay ( CIA ) , using anti-r7,t8-dihydroxy-t-9,10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene ( BPDE)-DNA antiserum , which measures both BPdG and the other stable BP-DNA adducts . When mice were fed 100 ppm BP for 28 days , BP-induced DNA damage measured in esophagus , liver and lung was typically higher in Xpa(-/-)p53(+/-) mice , compared with WT mice . This result is consistent with the previously observed tumor susceptibility of Xpa(-/-)p53(+/-) mice . BPdG , the major DNA adduct associated with tumorigenicity , was the primary DNA adduct formed in esophagus ( a target tissue in the mouse ) , whereas total BP-DNA adducts predominated in higher levels in the liver ( a non-target tissue in the mouse ) . In an attempt to lower BP-induced DNA damage , we fed the WT and Xpa(-/-)p53(+/-) mice 0.3% chlorophyllin ( CHL ) in the BP-containing diet for 28 days . The addition of CHL resulted in an increase of BP-DNA adducts in esophagus , liver and lung of WT mice , a lowering of BPdG in esophagi of WT mice and livers of Xpa(-/-)p53(+/-) mice and an increase of BPdG in livers of WT mice . Therefore , the addition of CHL to a BP-containing diet showed a lack of consistent chemoprotective effect , indicating that oral CHL administration may not reduce PAH-DNA adduct levels consistently in human organs .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

The studies in our laboratory have clearly demonstrated that idarubicin can undergo reductive bioactivation by NADPH-cytochrome P450 reductase to free radicals with resulting formation of DNA strand breaks , which can potentially contribute to its genotoxic effects [ Celik , H. , Arinç , E. , Bioreduction of idarubicin and formation of ROS responsible for DNA cleavage by NADPH-cytochrome P450 reductase and its potential role in the antitumor effect . J Pharm Pharm Sci , 11(4):68-82 , 2008 ] . In the current study , our aim was to investigate the possible protective effects of several phenolic antioxidants , quercetin , rutin , naringenin , resveratrol and trolox , against the DNA-damaging effect of idarubicin originating from its P450 reductase-catalyzed bioactivation . METHODS DNA damage was measured by detecting single-strand breaks in plasmid pBR322 DNA using a cell-free agarose gel method . RESULTS Our results indicated that , among the compounds tested , quercetin was the most potent antioxidant in preventing DNA damage . Quercetin significantly decreased the extent of DNA strand breaks in a dose-dependent manner ; 100 microM of quercetin almost completely inhibited the DNA strand breakage . Unlike quercetin , its glycosidated conjugate rutin , failed to provide any significant protection against idarubicin-induced DNA strand breaks except at the highest concentration tested ( 2 mM ) . The protective effects of other antioxidants were significantly less than that of quercetin even at high concentrations . Quercetin was found to be also an effective protector against DNA damage induced by mitomycin C. CONCLUSION We conclude that quercetin , one of the most abundant flavonoids in the human diet , is highly effective in reducing the DNA damage caused by the antitumor agents , idarubicin and mitomycin C , following bioactivation by P450 reductase .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

He was of Greek descent . His medical history was remarkable for nasal polyps , which were surgically removed 15 years earlier . Initially , he had been treated with antibiotics , without improvement . Several days before admission , chest radiography revealed pulmonary infiltrates in the left lower lobe . On admission , physical examination revealed a well-orientated man in mild distress , with inspiratory rhonchi at the lower part of the left lung and scattered erythematous nodules of variable size , some of which were ulcerated . Laboratory values were notable for leukopenia , 3.3 x 10(9)/L ; total protein , 5.9 g/dL ; globulin , 2.2 g/dL ; serum glutamic oxaloacetic transaminase , 86 IU/L ; serum glutamic pyruvic transaminase , 71 IU/L ; and lactate dehydrogenase , 519 U/L . Computed tomograph ( CT ) of the chest showed multiple alveolar opacities bilaterally ( Figure 2 ) . Fiberoptic bronchoscopy did not reveal any important pathologic findings . Results of bronchial biopsy , cytology of bronchoalveolar lavage , washing , brushing , and sputum following bronchoscopy were negative . CT of the brai and sinonasal area revealed an abnormal low-density mass in the left nasal area . CT findings of the abdomen were negative , as were results of a bone marrow biopsy . There was no evidence of immunosuppression . The differential diagnosis , considering the evidence described , included granulomatous or infectious diseases , angiocentric lymphoproliferative lesions , and lymphomas . Biopsy of a skin lesion showed lymphoproliferative infiltration of the dermis with a follicular and angiocentric growth pattern and regional epidermal necrosis . Immunohistochemical stains showed that the tumor cell were positive for CD56 and CD3 ( cytoplasmic positivity ) and expressed the cytotoxic proteins T-cell intracellular antigen and granzyme B ( Figure 3 ) They lacked TdT , CD34 , CD7 , CD8 , TCL-1 , and CD123 . Findings from an in situ hybridization study for Epstein-Barr virus were negative . Give this result , molecular analysis ofT-cell receptor ( TCR ) gene rearrangements was performed using polymerase chain reaction-based TCR-gamma gene , wit negative results . The morphology and the immunophenotype were consistent with natural killer/T-cell lymphoma , nasal-type . Nasal involvement must be first excluded to proceed to the diagnosis of nasal-type natural killer-cell lymphoma . Indeed , histologic examination of the nasal mass revealed its polypoid nature . Thus , the authors were led to the diagnosis of extranodal extranasal natural killer/T-cell lymphoma , nasal-type , CD56-positive , Ep stein-Barr virus-negative , TCR-negative . The patient received combination chemotherapy and completed 4 cycles of cyclophosphamide , doxorubicin vincristine , and prednisone every 14 days for 2 months . Skin lesions improved , and there was no fever soon after the initiation of therapy . Reevaluatio after the fourth cycle , however , disclosed pulmonary infiltrations as well as leukemic infiltration of the central nervous system . The patient had receive systemic salvage chemotherapy and intrathecal infusions of methotrexate .

Chemotherapy resistance at relapse contributes heavily to treatment failure . The poor survival of patients with high-risk NBL prompted this investigation into novel treatment options with the objective of gaining a better understanding of resistance mechanisms . On the basis of previous work and on data from publicly available studies , the authors hypothesized that human epidermal growth factor receptor 4 ( Her4 ) contributes to resistance . METHODS Her4 expression was reduced with small-hairpin RNA ( shRNA ) to over express intracellular HER4 , and the authors tested its impact on tumor cell survival under various culture conditions . The resulting changes in gene expression after HER4 knockdown were measured by using a messenger RNA ( mRNA ) array . RESULTS HER4 expression was up-regulated in tumor spheres compared with the expression in monolayer culture . With HER4 knockdown , NBL cells became less resistant to anoikis and serum starvation . Moreover , HER4 knockdown increased the chemosensitivity of NBL cells to cisplatin , doxorubicin , etoposide , and activated ifosfamide . In mRNA array analysis , HER4 knockdown predominately altered genes related to cell cycle regulation . In NBL spheres compared with monolayers , cell proliferation was decreased , and cyclin D expression was reduced . HER4 knockdown reversed cyclin D suppression . Overexpressed intracellular HER4 slowed the cell cycle and induced chemoresistance . CONCLUSIONS The current results indicated that HER4 protects NBL cells from multiple exogenous apoptotic stimuli , including anoikis , nutrient deficiency , and cytotoxic chemotherapy . The intracellular fragment of HER4 was sufficient to confer this phenotype . HER4 functions as a cell cycle suppressor , maintaining resistance to cellular stress . The current findings indicate that HER4 overexpression may be associated with refractory disease , and HER4 may be an important therapeutic target .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors;resisting cell death" } ]

MATERIALS AND METHODS The cell lines used were the ovarian carcinoma A2780s and a radiation-resistant derivative A2780cp . Radiation response was measured in terms of cell survival , recovery of sublethal ( SLD ) and potentially lethal damage ( PLD ) , induction of and recovery of DNA strand breaks , and fidelity of DNA repair using a cell-free plasmid assay . RESULTS While A2780cp was more resistant to radiation than A2780s , it showed less ability for recovery of SLD and PLD . DNA strand-break induction was the same for both cell lines , while only at very high doses did A2780cp show greater DNA strand-break recovery than A2780s . Fidelity of rejoining DNA was significantly higher in the A2780cp cell line . CONCLUSION The difference in radiosensitivity between these two cell lines was not related to recovery of PLD or SLD or to the induction of DNA damage . It appears that fidelity of DNA rejoining , which was significantly higher in the resistant cell line , may be related to the difference in radiosensitivity .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Especially , lung cancer is top-ranked in cancer-associated human death . Therefore , effective strategy is strongly required for the management of lung cancer . In the present study , we found that novel daphnane diterpenoids , yuanhualine ( YL ) , yuanhuahine ( YH ) and yuanhuagine ( YG ) isolated from the flower of Daphne genkwa ( Thymelaeaceae ) , exhibited potent anti-proliferative activities against human lung A549 cells with the IC50 values of 7.0 , 15.2 and 24.7 nM , respectively . Flow cytometric analysis revealed that the daphnane diterpenoids induced cell-cycle arrest in the G0/G1 as well as G2/M phase in A549 cells . The cell-cycle arrests were well correlated with the expression of checkpoint proteins including the up-regulation of cyclin-dependent kinase inhibitor p21 and p53 and down-regulation of cyclin A , cyclin B1 , cyclin E , cyclin dependent kinase 4 , cdc2 , phosphorylation of Rb and cMyc expression . In the analysis of signal transduction molecules , the daphnane diterpenoids suppressed the activation of Akt , STAT3 and Src in human lung cancer cells . The daphnane diterpenoids also exerted the potent anti-proliferative activity against anticancer-drug resistant cancer cells including gemcitabine-resistant A549 , gefitinib- , erlotinib-resistant H292 cells . Synergistic effects in the growth inhibition were also observed when yuanhualine was combined with gemcitabine , gefitinib or erlotinib in A549 cells . Taken together , these findings suggest that the novel daphnane diterpenoids might provide lead candidates for the development of therapeutic agents for human lung cancers .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

However , current understanding of LKB1 function is largely limited to the results from cancer cells , and how LKB1 inactivation initiates malignant transformation in normal cells remains unclear . Here we ablated endogenous expression of LKB1 in two normal cell lines : human embryonic kidney 293T cells ( HEK-293T cells ) and human umbilical vein endothelial cells ( HUVECs ) by LKB1-specific short hairpin RNAs . Downregulation of endogenous LKB1 lead to a facilitated G(1)/S transition , accompanied by a concomitant increase in Rb phosphorylation ( Ser(807/811) ) . Furthermore , reduced expression of p53 and p16 was observed in LKB1 ablated cells , while no differences were detected for cyclin D1 and cyclin E. These results jointly suggest that endogenous LKB1 knockdown accelerates cell cycle progression through G(1)/S checkpoint in HEK-293T cells and HUVECs , which is at least in part , mediated by decline of p53 and p16 pathways . Our findings provided a plausible mechanism by which loss of LKB1 expression in normal cells contributes to the formation of malignancies .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors" } ]

Using confocal microscopy we have confirmed our previous observation that heat-stressed apoptotic 12B1-D1 leukemia cells ( BCR-ABL(+) ) express HSP60 and HSP72 on their surface . To explore how the immune system distinguishes stressed from nonstressed apoptotic tumor cells , we analyzed the responses of dendritic cells to these 2 types of apoptotic cells . We found that nonstressed and heat-stressed apoptotic 12B1-D1 cells were taken up by dendritic cells in a comparable fashion . However , when stressed apoptotic 12B1-D1 cells were coincubated with immature dendritic cells for 24 hours , this resulted in greater up-regulation of costimulatory molecules ( CD40 , CD80 , and CD86 ) on the surface of dendritic cells . Moreover , stressed apoptotic 12B1-D1 cells were more effective in stimulating dendritic cells to secrete interleukin-12 ( IL-12 ) and in enhancing their immunostimulatory functions in mixed leukocyte reactions . Furthermore , we demonstrated that immunization of mice with stressed apoptotic 12B1-D1 cells induced the secretion of T helper-1 ( T(H)1 ) profile of cytokines by spleen cells . Splenocytes from mice immunized with stressed apoptotic cells , but not nonstressed ones , were capable of lysing 12B1-D1 and the parental 12B1 line , but not a B-cell leukemia line , A20 . Our data indicate that stressed apoptotic tumor cells are capable of providing the necessary danger signals , likely through increased surface expression of heat shock proteins ( HSPs ) , resulting in activation/maturation of dendritic cells and , ultimately , the generation of potent antitumor T-cell responses .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction;resisting cell death" } ]

The present study investigated whether ALA disrupts the Warburg effect , which represents a shift in ATP generation from oxidative phosphorylation to glycolysis , protecting tumor cells against oxidative stress-mediated apoptosis . The human lung carcinoma cell line A549 exposed to ALA exhibited enhanced oxidative phosphorylation , which was indicated by an increase in COX protein expression and oxygen consumption . Furthermore , ALA suppressed glycolysis-mediated acidosis . This normalization of the ATP metabolic pathways significantly increased the generation of superoxide anion radical ( O2•- ) and the functional expression of active caspase-3 , leading to caspase-dependent apoptosis . These data demonstrate that ALA inhibits the Warburg effect and induces cancer cell death .

We have now obtained evidence that transforming growth factor-beta 1 ( TGF-beta 1 ) and glucocorticoids are negative regulators for HGF gene expression . When TGF-beta 1 or dexamethasone was added to cultures of MRC-5 human embryonic lung fibroblasts and HL-60 human promyelocytic leukemic cells , the amount of HGF secreted into the culture medium was inhibited to 30-40% of that of control cultures by 10 ng/ml TGF-beta 1 and to 40-50% by 10(-6) M dexamethasone . The inhibitory effect of TGF-beta 1 and dexamethasone on HGF synthesis in MRC-5 cells was additive , thereby suggesting that TGF-beta 1 and dexamethasone exert effects through distinct mechanisms . Hydrocortisone also inhibited HGF synthesis with the same potency as dexamethasone ; however , testosterone , estriol , and beta-estradiol had no effect . The rate of HGF synthesis in MRC-5 cells , as measured by pulse labeling with [ 35S]methionine and subsequent immunoprecipitation , was suppressed to 30-40% of the control with 10 ng/ml TGF-beta 1 , and to 30-45% by 10(-6) M dexamethasone . HGF mRNA levels in MRC-5 cells and HL-60 cells were dose-dependently suppressed by TGF-beta 1 and dexamethasone ; 10 ng/ml TGF-beta 1 suppressed HGF mRNA levels to 32% and 35% of control culture , respectively , in MRC-5 cells and HL-60 cells , and 10(-6) M dexamethasone suppressed to 43% and 38% , respectively . Thus , TGF-beta 1 and glucocorticoids seem to inhibit HGF synthesis by suppressing the expression of the HGF gene . We propose that a negative regulation of HGF gene expression by TGF-beta 1 or glucocorticoids may be involved in physiological or pathological processes during tissue regeneration .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

In the neutral comet assay , the rate of DNA exit was found to be dependent on the topological state of DNA , which was influenced by either ethidium bromide or a low radiation dose . The results clearly show that the comet tail is formed by extended DNA loops : the loop extension , being reversible when the DNA torsional constraint remains in the loops , is favored when the constraint is relaxed . The kinetics of the comet formation in the case of a high radiation dose points out that accumulation of the single-strand breaks causes DNA fragmentation . In contrast to the neutral comet assay , the alkaline comet assay is not related to the chromatin loops . Our results imply that the alkaline treatment induces detachment of the loops from the nuclear matrix , and the comet tail is formed by ssDNA fragments , the ends of which are pulled out from the comet head by electric force . We suggest that the kinetic approach can be considered as an important improvement of the comet assay .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

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

This glycolytic shift , called the Warburg effect , provides a mechanistic basis for targeting glycolysis to suppress carcinogenesis through the use of dietary caloric restriction and energy restriction-mimetic agents ( ERMA ) . We recently reported the development of a novel class of ERMAs that exhibits high potency in eliciting starvation-associated cellular responses and epigenetic changes in cancer cells though glucose uptake inhibition . The lead ERMA in this class , OSU-CG5 , decreases the production of ATP and NADH in LNCaP prostate cancer cells . In this study , we examined the effect of OSU-CG5 on the severity of preneoplastic lesions in male transgenic adenocarcinoma of the mouse prostate ( TRAMP ) mice . Daily oral treatment with OSU-CG5 at 100 mg/kg from 6 to 10 weeks of age resulted in a statistically significant decrease in the weight of urogenital tract and microdissected dorsal , lateral , and anterior prostatic lobes relative to vehicle controls . The suppressive effect of OSU-CG5 was evidenced by marked decreases in Ki67 immunostaining and proliferating cell nuclear antigen ( PCNA ) expression in the prostate . OSU-CG5 treatment was not associated with evidence of systemic toxicity . Microarray analysis indicated a central role for Akt , and Western blot analysis showed reduced phosphorylation and/or expression levels of Akt , Src , androgen receptor , and insulin-like growth factor-1 receptor in prostate lobes . These findings support further investigation of OSU-CG5 as a potential chemopreventive agent .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Immunomodulatory agents can interfere with the inflammation that feeds cancer , but their impact on the transformed cell is poorly understood . The calcium/calcineurin signaling pathway , through activation of NFAT , is essential for effective immune responses , and its inhibitors cyclosporin A ( CsA ) and FK506 are used in the clinics to suppress immunity . Moreover , the kinases GSK3β and mTOR , modulated by PI-3K/Akt , can inhibit NFAT activity , suggesting a cross-talk between the calcium and growth factor signaling pathways . Both NFAT and mTOR activity have been associated with tumorigenesis . We therefore investigated the impact of calcineurin and PI-3K/mTOR inhibition in growth of human colon carcinoma cells . We show that despite the efficient inhibition of NFAT1 activity , FK506 promotes tumor growth , whereas CsA inhibits it due to a delay in cell cycle progression and induction of necroptosis . We found NFκB activation and mTORC1 activity not to be altered by CsA or FK506 . Similarly , changes to mitochondrial homeostasis were equivalent upon treatment with these drugs . We further show that , in our model , NFAT1 activation is not modulated by PI3K/mTOR . We conclude that CsA slows cell cycle progression and induces necroptosis of human carcinoma cell lines in a TGFβ- , NFAT- , NFκB- and PI3K/mTOR-independent fashion . Nevertheless , our data suggest that CsA , in addition to its anti-inflammatory capacity , may target transformed colon and esophagus carcinoma cells without affecting non-transformed cells , promoting beneficial tumoristatic effects .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;tumor promoting inflammation" } ]

Methods EC9706 cells were treated with bufalin at various concentrations , and then the cell growth inhibition of EC9706 cells was examined by CCK-8 assay and the 50% inhibitory concentration ( IC(50) ) was calculated.Cell cycle analysis was performed by flow cytometry with PI staining , and nucleus morphology of apoptosis were observed by fluorescence microscopy with Hoechst 33342 staining . The apoptotic index was measured by flow cytometry with Annexin V-FITC/PI double staining. hTERT subcellular localization and protein expression were determined by Western blotting and multiple immunofluorescence labling combined with laser confocal scanning microscopy . Results The proliferation of EC 9706 cells was significantly inhibited by bufalin along with the increase of processing time and concentrations ( p<0.01 ) . After the EC9706 cells were exposed to 100 nmol/L bufalin,the number of cells gradually decreased in G(1) phase and increased in S and G(2)/M phases(p<0.05) . The typical nucleus morphological changes of apoptosis were observed and the apoptotic index was increased(p<0.01) . The expression of hTERT decreased in nucleus but increased in mitochondria(p<0.05) . Conclusions Bufalin can inhibit the proliferation of human esophageal squamous carcinoma EC9706 cells in a time- and dose-dependent manner . It can arrest cell cycle in S and G(2)/M phases and induce the apoptosis of EC 9706 cells. hTERT is localized in both nucleus and mitochondria,and can be partially translocated from nucleus to mitochondria during the bufalin-induced apoptosis .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;resisting cell death" } ]

It also shows anti-tumor activity in mouse tumor models and is currently in phase III clinical trials . In animal tests and clinical trials Onc shows lesser toxicity and fewer side effects compared to most chemotherapeutic drugs . Intriguingly , repeated infusions of this protein do not cause apparent immunological reactions in patients . The aim of the present study was to investigate sensitivity to Onc of human lymphocytes during their mitogenic stimulation in response to the polyvalent mitogen phytohemagglutinin ( PHA ) , and in mixed allogeneic lymphocyte cultures . Unexpectedly , we observed that frequency of cells undergoing activation-induced apoptosis was markedly increased in all cultures containing Onc . Apoptosis was measured by flow cytometry using markers that detect activation of caspases , the in situ presence of DNA strand breaks , and loss of fragmented DNA ( 'sub-G1 ' cell subpopulation ) . The enhancement of frequency of activation-induced apoptosis ( up to 244% ) was observed at 4.2-83 nM Onc concentration , which is at least an order magnitude lower than its minimal concentration reported to affect proliferation or induce apoptosis of leukemic and solid tumor cell lines . The cell cycle progression of lymphocytes that responded to PHA mitogenically was not affected at 8.3 or 83 nM Onc concentration . Because activation-induced apoptosis is the key mechanism regulating several in vivo immunological functions including induction of tolerance , the observed effects of Onc may explain the apparent lack of immune reactions to this protein in treated patients . The propensity of Onc to potentiate the activation-induced apoptosis suggests that this drug may have clinical utility as immunomodulating agent , e.g. , to suppress transplant rejection or treat autoimmune diseases .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;avoiding immune destruction" } ]

We investigated here the effect of clotrimazole ( 1-(alpha-2-chlorotrityl)imidazole ) , the antifungal azole derivative , which was recently recognized as calmodulin antagonist , on the levels of glucose 1,6-bisphosphate and fructose 1,6-bisphosphate , the two stimulatory signal molecules of glycolysis , and on ATP content and cell viability in LL/2 Lewis lung carcinoma cells and CT-26 colon adenocarcinoma cells . We found that clotrimazole induced a significant , dose- and time-dependent reduction in the levels of glucose 1,6-bisphosphate , fructose 1,6-bisphosphate , ATP , and cell viability . These findings suggest that clotrimazole causes a reduction in glycolysis and ATP levels , which eventually leads to cell destruction after 3 h of treatment . Since cell proliferation was also reported to be inhibited by calmodulin antagonists , this substance is most promising agent in treatment of cancer by inhibiting both cell proliferation and the glycolytic supply of ATP required for cancer cell growth .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

In this study , we identified migration inducting gene-7 ( MIG-7 ) protein as critical for COX-2/prostaglandin E2 ( PGE2)- and Akt/GSK-3β-dependent tumor invasion/metastasis . COX-2/PGE2 activated EP4 to enhance Akt and GSK-3β phosphorylation and β-catenin/T-cell factor/lymphoid enhancer factor signaling leading to MIG-7 upregulation . RNAi-mediated attenuation of MIG-7 blocked COX-2/PGE2- and Akt/GSK-3β-mediated migration/invasion effects . Furthermore , MIG-7 protein inhibited protein phosphatase 2A to sustain Akt/GSK-3β phosphorylation and cancer-cell migration/invasion . Cancer cells overexpressing MIG-7 exhibited increased expression of ZEB-1 and Twist in parallel with epithelial-mesenchymal transition , metastasis and cancer lethality .

We previously demonstrated that deregulation of epigenetic regulators is a common event in human HCC . Suppressor of variegation 3-9 homolog 1 ( SUV39H1 ) , the prototype of histone methyltransferase , is the major enzyme responsible for histone H3 lysine 9 trimethylation , which , essentially , is involved in heterochromatin formation , chromosome segregation , and mitotic progression . However , the implication of SUV39H1 in hepatocarcinogenesis remains elusive . In this study , we found that SUV39H1 was frequently up-regulated in human HCCs and was significantly associated with increased Ki67 expression ( P &lt ; 0.001 ) and the presence of venous invasion ( P = 0.017 ) . To investigate the role of SUV39H1 in HCC development , both gain- and loss-of-function models were established . SUV39H1 overexpression remarkably enhanced HCC cell clonogenicity , whereas knockdown of SUV39H1 substantially suppressed HCC cell proliferation and induced cell senescence . In addition , ectopic expression of SUV39H1 increased the migratory ability of HCC cells , whereas a reduced migration rate was observed in SUV39H1 knockdown cells . The significance of SUV39H1 in HCC was further demonstrated in a nude mice model ; SUV39H1 knockdown drastically inhibited in vivo tumorigenicity and abolished pulmonary metastasis of HCC cells . We also identified microRNA-125b ( miR-125b ) as a post-transcriptional regulator of SUV39H1 . Ectopic expression of miR-125b inhibited SUV39H1 3'-untranslated-region-coupled luciferase activity and suppressed endogenous SUV39H1 expression at both messenger RNA and protein levels . We have previously reported frequent down-regulation of miR-125b in HCC . Interestingly , miR-125b level was found to be inversely correlated with SUV39H1 expression ( P = 0.001 ) in clinical specimens . Our observations suggested that miR-125b down-regulation may account for the aberrant SUV39H1 level in HCC . CONCLUSION Our study demonstrated that SUV39H1 up-regulation contributed to HCC development and metastasis . The tumor-suppressive miR-125b served as a negative regulator of SUV39H1 .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;activating invasion and metastasis" } ]

METHODS Three cell lines ( HPAF-II , PL45 , HPAC ) were treated with UK ( 5 , 10 and 20 μM ) for 48 h , or left untreated . Secreted protein acidic and rich in cysteine ( SPARC ) mRNA levels were assessed by real-time PCR . Matrix metalloproteinases ( MMP)-2 and -9 activity was analyzed by SDS zymography ; SPARC protein levels in cell lysates and supernatants were determined by Western blot . Cell cycle was determined by flow cytometric analysis , and invasion by matrigel invasion assay . RESULTS UK down-regulated MMP-2 and MMP-9 , suggesting that UK may decrease pancreatic cancer cell invasion , as confirmed by the matrigel invasion assay . SPARC protein down-regulation in supernatants points to an inhibition by UK of extracellular matrix remodeling in the tumor microenvironment .

Its proliferation is strictly dependent on the presence of hematopoietic growth factors including erythropoietin ( Epo ) , granulocyte-macrophage colony-stimulating factor ( GM-CSF ) , and interleukin-3 ( IL-3 ) . We investigated the differentiation capacities of this cell line under the action of several growth factors , using immunomarkers , flow cytometry , and ultrastructural techniques . In the presence of GM-CSF and IL-3 , eosinophil and basophil promyelocytes were detected , as well as a few cells with erythroid and megakaryocytic ( MK ) differentiation features . In contrast , Epo induced a marked erythroid differentiation with an increase of glycophorin A expression , accompanied by a few hemoglobinized cells . Differentiation induced by the growth factors took 24 to 48 hours to begin , and increased with cell passages to a plateau at 2 weeks of culture . However , this was not only due to a cell selection because the differential effects of Epo and GM-CSF were observed from a single cell clone and the phenotype could be reversed by opposite growth factors , even after a long period of culture . We subsequently investigated the phenotype of UT-7 in the presence of combinations of Epo , IL-3 , and GM-CSF , and showed that GM-CSF and IL-3 act predominantly over Epo . This effect was mediated by a rapid downmodulation of Epo receptors by GM-CSF at messenger RNA and binding sites levels , without a change in receptor affinities . On the other hand , Epo had no effect on number and affinity of GM-CSF receptors . This study shows that UT-7 is a growth factor-dependent pluripotent cell line in which commitment may be directed by a hierarchical action of growth factors through an early and rapid transmodulation of growth factor receptors .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Linker substitution mutations were constructed across the entire Saccharomyces cerevisiae chromosomal origin , ARS1 . Functional studies of these mutants revealed one essential element ( A ) , which includes a match to the ARS consensus sequence , and three additional elements ( B1 , B2 , and B3 ) , which collectively are also essential for origin function . These four elements arranged exactly as in ARS1 , but surrounded by completely unrelated sequence , functioned as an efficient origin . Element B3 is the binding site for the transcription factor-origin binding protein ABF1 . Other transcription factor binding sites substitute for the B3 element and a trans-acting transcriptional activation domain is required . The multipartite nature of a chromosomal replication origin and the role of transcriptional activators in its function present a striking similarity to the organization of eukaryotic promoters .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

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

Consequently , chromatin-modifying enzymes , including adenosine triphosphate-dependent chromatin remodeling enzymes , play an important role in the management of DNA double-strand breaks ( DSBs ) . Here , we show that the p400 ATPase is required for DNA repair by homologous recombination ( HR ) . Indeed , although p400 is not required for DNA damage signaling , DNA DSB repair is defective in the absence of p400 . We demonstrate that p400 is important for HR-dependent processes , such as recruitment of Rad51 to DSB ( a key component of HR ) , homology-directed repair , and survival after DNA damage . Strikingly , p400 and Rad51 are present in the same complex and both favor chromatin remodeling around DSBs .

However , the factors that regulate this protein remain unclear . In renal carcinomas , hypoxic conditions enhance the expression of angiogenic factors that help adapt tumour cells to their hostile environment . Therefore , we hypothesized that anti-angiogenic factors should correspondingly be dampened . Indeed , we found that hypoxia decreased the thrombospondin-1 protein in several clear cell renal carcinoma cell lines ( ccRCC ) , although no transcriptional regulation was observed . Furthermore , we proved that hypoxia stimulates multiple signals that independently contribute to diminish thrombospondin-1 in ccRCC , which include a decrease in the activity of oxygen-dependent prolylhydroxylases ( PHDs ) and activation of the PI3K/Akt signalling pathway . In addition , thrombospondin-1 regulation in hypoxia proved to be important for ccRCC cell migration and invasion .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

Previously , we demonstrated that delta-tocotrienol inhibits NSCLC cell proliferation , invasion and induces apoptosis by down-regulation of the Notch-1 signaling pathway . The objective of this study was to investigate whether delta-tocotrienol , could enhance the anticancer effects of cisplatin . Treatment with a combination of delta-tocotrienol and cisplatin resulted in a dose-dependent , significant inhibition of cell growth , migration , invasiveness , and induction of apoptosis in NSCLC cells , as compared to the single agents . This was associated with a decrease in NF-κB DNA binding activity , decrease in Notch-1 , Hes-1 , Bcl-2 and increase in cleaved Caspase-3 and PARP expressions . These results suggest that down-regulation of Notch-1 , via inhibition of NF-κB signaling pathways by delta-tocotrienol and cisplatin , in combination , could provide a potential novel approach for tumor arrest in NSCLC , while lowering the effective dose of cisplatin .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;resisting cell death;sustaining proliferative signaling" } ]

The present work ( the DART study ) investigated the extent of inter-individual variation in DNA damage , the capacity for base excision repair ( BER ) and the responses of both variables to supplementation with an antioxidant supplement for 6 weeks . There was a wide inter-individual variation in endogenous lymphocyte DNA strand breaks ( 8-fold variation ) , in damage after a challenge with H2O2 ( 16-fold variation ) and in DNA repair ( 41-fold variation ) measured using the comet assay . When stratified into tertiles according to the pre-supplementation level of endogenous DNA damage , there was a statistically significant decrease in DNA damage after supplementation in the tertile with the highest pre-supplementation level of damage . There was no effect of supplementation on BER . Endogenous DNA damage level before supplementation was significantly different ( P = 0.037 ) between the three genotypes for the Val16Ala single nucleotide polymorphism in manganese superoxide dismutase ( rs4880 ) with individuals homozygous/wild type showing less damage than those carrying the alanine variant .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

As chronic inflammations are associated with malignancies , it is important to prevent inflammation-mediated neoplastic formation , promotion and/or progression . One possible intervention will be using cancer chemopreventive agents such as curcumin ( CUR ) , a potent anti-inflammatory and anti-oxidative stress compound . Polyunsaturated fatty acids ( PUFA ) such as docosahexaenoic acid ( DHA ) or eicosapentaenoic acid ( EPA ) are potent anti-inflammatory agents by decreasing the production of inflammatory eicosanoids , cytokines , and reactive oxygen species ( ROS ) . The present study aims at examining whether CUR with DHA or EPA would have synergistic anti-inflammatory effects in RAW 264.7 cells . Non-toxic concentrations of single and combination of the compounds were investigated at 6 , 12 and 24h . The nitric oxide ( NO ) suppression effects were most prominent at 24h . All the combinations of CUR and DHA or EPA with lower concentrations of CUR 5 microM and 25 microM of DHA or EPA were found to have synergistic effects in suppressing LPS-stimulated NO and endogenous NO levels . Importantly , very low doses of CUR 2.5 microM and DHA or EPA of 0.78 microM could synergistically suppress the LPS-induced prostaglandin E(2) ( PGE(2) ) . The combinations were also found to suppress iNOS , COX-2 , 5-lipoxygenase ( 5-LOX ) and cPLA(2) but induce HO-1 .

A reductionist view would predict that a small number of basic pathways are generally perturbed by arsenic , and manifest as diverse diseases . Following an initial observation that arsenite-exposed cells in culture acidify their media more rapidly than control cells , the report here shows that low level exposure to arsenite ( 75ppb ) is sufficient to induce aerobic glycolysis ( the Warburg effect ) as a generalized phenomenon in cultured human primary cells and cell lines . Expanded studies in one such cell line , the non-malignant pulmonary epithelial line , BEAS-2B , established that the arsenite-induced Warburg effect was associated with increased accumulation of intracellular and extracellular lactate , an increased rate of extracellular acidification , and inhibition by the non-metabolized glucose analog , 2-deoxy-D-glucose . Associated with the induction of aerobic glycolysis was a pathway-wide induction of glycolysis gene expression , as well as protein accumulation of an established glycolysis master-regulator , hypoxia-inducible factor 1A .

E. , and Folkman , J . ( 1989 ) J. Cell Biol. 109 , 317-330 ) , thereby mimicking angiogenesis . To assess the role of glycoproteins bearing asparagine-linked oligosaccharides in this process , we tested the effect of oligosaccharide processing inhibitors on the formation of capillary tubes . Deoxymannojirimycin , a compound that prevents synthesis of hybrid and complex-type oligosaccharides , inhibited the formation of capillary tubes . In contrast , swainsonine , an inhibitor that blocks synthesis of complex- but not hybrid-type oligosaccharides , did not inhibit tube formation . Lectin affinity chromatography of 2-[3H] mannose-labeled glycopeptides from endothelial cells induced to form tubes did not reveal a striking difference in the spectrum of oligosaccharides compared to uninduced cells . Since endothelial cells formed tubes normally in the presence of swainsonine , we analyzed glycopeptides from swainsonine-treated induced and uninduced cells . Cells induced to form tubes were enriched in monosialylated hybrid-type oligosaccharides sensitive to alpha-fucosidase , beta-galactosidase , and beta-N-acetylhexosaminidase , suggestive of sialyl Lewis-X determinants . We used an enzyme-linked immunoassay to measure sialyl Lewis-X epitopes on capillary endothelial cells and found that both induced and uninduced cells expressed sialyl Lewis-X epitopes . Deoxymannojirimycin and , to a lesser extent , swainsonine reduced the level of sialyl Lewis-X epitopes in cells induced to form capillary tubes , but neither compound affected the level of epitopes in cell monolayers . We conclude that synthesis of at least hybrid-type oligosaccharides is required for capillary tube formation in vitro and that an increase in monosialylated , fucosylated glycans on asparagine-linked oligosaccharides occurs during this process .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

Achaete-scute complex homolog-1 ( Ascl1 ) is a member of the basic helix-loop-helix ( bHLH ) transcription factor family that has multiple functions in the normal and neoplastic lung such as the regulation of neuroendocrine differentiation , prevention of apoptosis and promotion of tumor-initiating cells . We now show that Ascl1 directly regulates matrix metalloproteinase-7 ( MMP-7 ) and O(6)-methylguanine-DNA methyltransferase ( MGMT ) . Loss- and gain-of-function experiments in human bronchial epithelial and lung carcinoma cell lines revealed that Ascl1 , MMP-7 and MGMT are able to protect cells from the tobacco-specific nitrosamine NNK-induced DNA damage and the alkylating agent cisplatin-induced apoptosis . We also examined the role of Ascl1 in NNK-induced lung tumorigenesis in vivo . Using transgenic mice which constitutively expressed human Ascl1 in airway lining cells , we found that there was a delay in lung tumorigenesis . We conclude that Ascl1 potentially enhances DNA repair through activation of MMP-7 and MGMT which may impact lung carcinogenesis and chemoresistance . The study has uncovered a novel and unexpected function of Ascl1 which will contribute to better understanding of lung carcinogenesis and the broad implications of transcription factors in tobacco-related carcinogenesis .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;resisting cell death" } ]

The MDA-MB-453 cell line is the prototypical model of this breast cancer subtype ; its proliferation is stimulated by androgens such as 5α-dihydrotestosterone ( DHT ) but inhibited by the progestin medroxyprogesterone acetate ( MPA ) via AR-mediated mechanisms . We report here that the AR gene in MDA-MB-453 cells contains a G-T transversion in exon 7 , resulting in a receptor variant with a glutamine to histidine substitution at amino acid 865 ( Q865H ) in the ligand binding domain . Compared with wild-type AR , the Q865H variant exhibited reduced sensitivity to DHT and MPA in transactivation assays in MDA-MB-453 and PC-3 cells but did not respond to non-androgenic ligands or receptor antagonists . Ligand binding , molecular modeling , mammalian two-hybrid and immunoblot assays revealed effects of the Q865H mutation on ligand dissociation , AR intramolecular interactions , and receptor stability . Microarray expression profiling demonstrated that DHT and MPA regulate distinct transcriptional programs in MDA-MB-453 cells . Gene Set Enrichment Analysis revealed that DHT- but not MPA-regulated genes were associated with estrogen-responsive transcriptomes from MCF-7 cells and the Wnt signaling pathway . These findings suggest that the divergent proliferative responses of MDA-MB-453 cells to DHT and MPA result from the different genetic programs elicited by these two ligands through the AR-Q865H variant . This work highlights the necessity to characterize additional models of molecular apocrine breast cancer to determine the precise role of AR signaling in this breast cancer subtype .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

To determine whether p63 proteins , members of the family of p53-related genes , are also involved in this process , we examined their expression in serially passaged rat embryo fibroblasts . Upon senescence , two truncated DeltaNp63 proteins decreased in abundance whereas two TAp63 isoforms accumulated. 2-D gel analysis showed that the DeltaNp63 proteins underwent post-translational modifications in both proliferating and senescent cells . Direct binding of DeltaNp63 proteins to a p53 consensus motif was greater in proliferating cells than senescent cells . In contrast p63alpha isoforms bound to DNA in a p53 dependent manner and this was higher in senescent cells than proliferating cells . An interaction of p63alpha proteins with SV40 large tumour antigen was also detected and ectopic expression of DeltaNp63alpha can extend the lifespan of rat embryo fibroblasts . Taken together the results indicate that p63 proteins may play a role in replicative senescence either by competition for p53 DNA binding sites or by direct interaction with p53 protein bound to DNA .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

Here , we classified six new variants as pathogenic or nonpathogenic by analysis of genetic information from families carrying 64 individual BRCA2 DNA binding domain ( DBD ) missense mutations using a multifactorial likelihood model of cancer causality . Next , we evaluated the use of a homology-directed DNA break repair ( HDR ) functional assay as a method for inferring the clinical relevance of VUS in the DBD of BRCA2 using 18 established nonpathogenic missense variants and all 13 established pathogenic missense mutations from the BRCA2 DBD . Compared with the known status of these variants based on the multifactorial likelihood model , the sensitivity of the HDR assay for pathogenic mutations was estimated at 100% [ 95% confidence interval ( CI ) : 75.3%-100% ] and specificity was estimated at 100% ( 95% CI : 81.5%-100% ) . A statistical classifier for predicting the probability of pathogenicity of BRCA2 DBD variants was developed using these functional results . When applied to 33 additional VUS , the classifier identified eight with 99% or more probability of nonpathogenicity and 18 with 99% or more probability of pathogenicity . Thus , in the absence of genetic evidence , a cell-based HDR assay can provide a probability of pathogenicity for all VUS in the BRCA2 DBD , suggesting that the assay can be used in combination with other information to determine the cancer relevance of BRCA2 VUS .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

Due to dismal prognosis and limited therapeutic intervention , chemoprevention has emerged as a viable approach to reduce the morbidity and mortality of HCC . Pomegranate fruit is a rich source of phytochemicals endowed with potent antioxidant and anti-inflammatory properties . We previously reported that pomegranate phytochemicals inhibit diethylnitrosamine ( DENA)-initiated hepatocarcinogenesis in rats though nuclear factor E2-related factor 2 ( Nrf2)-mediated antioxidant mechanisms . Since Nrf2 also acts as a key mediator of the nuclear factor-kappaB ( NF-κB)-regulated inflammatory pathway , our present study investigated the anti-inflammatory mechanisms of a pomegranate emulsion ( PE ) during DENA-induced rat hepatocarcinogenesis . Rats were administered with PE ( 1 or 10 g/kg ) 4 weeks before and 18 weeks following DENA initiation . There was a significant increase in hepatic expressions of inducible nitric oxide synthase , 3-nitrotyrosine , heat shock protein 70 and 90 , cyclooxygenase-2 and NF-κB in DENA-exposed rat livers . PE dose-dependently suppressed all aforementioned elevated inflammatory markers . A conspicuous finding of this study involves lack of cardiotoxicity of PE as assessed by monitoring cardiac function using noninvasive echocardiography . Our results provide substantial evidence that suppression of the inflammatory cascade through modulation of NF-κB signaling pathway may represent a novel mechanism of liver tumor inhibitory effects of PE against experimental hepatocarcinogenesis . Data presented here coupled with those of our earlier study underline the importance of simultaneously targeting two interconnected molecular circuits , namely , Nrf2-mediated redox signaling and NF-κB-regulated inflammatory pathway , by pomegranate phytoconstituents to achieve chemoprevention of HCC .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

PATIENTS Overall , 119 patients bearing a KRAS mutation in codon 12 were evaluated . All patients received cetuximab-based first-line chemotherapy within the Central European Cooperative Oncology Group ( CECOG ) , AIO KRK-0104 or AIO KRK-0306 trials . RESULTS Patients with KRAS codon 12 mutant mCRC showed a broad range of outcome when treated with cetuximab-based first-line regimens . Patients with tumors bearing a KRAS p.G12D mutation showed a strong trend to a more favorable outcome compared to other mutations ( overall survival 23.3 vs. 14-18 months ; hazard ratio 0.66 , range 0.43-1.03 ) . An interaction model illustrated that KRAS p.G12C was associated with unfavorable outcome when treated with oxaliplatin plus cetuximab . CONCLUSION The present analysis suggests that KRAS codon 12 mutation may not represent a homogeneous entity in mCRC when treated with cetuximab-based first-line therapy .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

In this pilot , randomized , double-blind , placebo-controlled clinical trial ( n = 47 ) , we assessed the effects of an antioxidant micronutrient combination ( 800 mg dl-alpha-tocopherol acetate , 24 mg beta-carotene , 1.0 g vitamin C , 200 microg l-selenomethionine , 7.2 mg riboflavin , 80 mg niacin , 60 mg zinc , 5 mg manganese ) given daily over 4 months on oxidative and inflammatory biomarkers in patients with a history of sporadic colorectal adenoma . Plasma tumor necrosis factor-alpha ( TNF-alpha ) , interleukin-6 , and F2-isoprostane concentrations were measured using ELISAs , and cystine ( CySS ) was measured using high-performance liquid chromatography . Plasma TNF-alpha concentration decreased in the active treatment group by 37% relative to the placebo group ( P = 0.002 ) , and CySS decreased by 19% ( P = 0.03 ) ; however , interleukin-6 and F2-isoprostane concentrations decreased in antioxidant-treated nonsmokers but increased in smokers , although these findings were not statistically significant . The decreases of TNF-alpha and CySS were more pronounced in nonsmokers . These data suggest that ( a ) an antioxidant micronutrient cocktail can modulate biomarkers of oxidative stress and inflammation in humans and ( b ) the effects of antioxidant micronutrient supplementation on biomarkers of inflammation and oxidative stress may differ according to smoking status .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

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

SIRT7 is a mammalian sirtuin whose biochemical activity , molecular targets and physiological functions have been unclear . Here we show that SIRT7 is an NAD(+)-dependent H3K18Ac ( acetylated lysine 18 of histone H3 ) deacetylase that stabilizes the transformed state of cancer cells . Genome-wide binding studies reveal that SIRT7 binds to promoters of a specific set of gene targets , where it deacetylates H3K18Ac and promotes transcriptional repression . The spectrum of SIRT7 target genes is defined in part by its interaction with the cancer-associated E26 transformed specific ( ETS ) transcription factor ELK4 , and comprises numerous genes with links to tumour suppression . Notably , selective hypoacetylation of H3K18Ac has been linked to oncogenic transformation , and in patients is associated with aggressive tumour phenotypes and poor prognosis . We find that deacetylation of H3K18Ac by SIRT7 is necessary for maintaining essential features of human cancer cells , including anchorage-independent growth and escape from contact inhibition . Moreover , SIRT7 is necessary for a global hypoacetylation of H3K18Ac associated with cellular transformation by the viral oncoprotein E1A . Finally , SIRT7 depletion markedly reduces the tumorigenicity of human cancer cell xenografts in mice . Together , our work establishes SIRT7 as a highly selective H3K18Ac deacetylase and demonstrates a pivotal role for SIRT7 in chromatin regulation , cellular transformation programs and tumour formation in vivo .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

In the last few years , many efforts have been addressed to identify p53-reactivating molecules able to restore the wild-type transcriptionally competent conformation of the mutated proteins . Here , we show that two of these compounds , CP-31398 and RITA , induce cell growth inhibition , apoptosis , and autophagy by activating p53/DNA binding and p53 phosphorylation ( Ser15 ) , without affecting the total p53 amount . These effects occur in both wild-type and mutant p53 pancreatic adenocarcinoma cell lines , whereas they are much less pronounced in normal human primary fibroblasts . Furthermore , CP-31398 and RITA regulate the axis SESN1-2/AMPK/mTOR by inducing AMPK phosphorylation on Thr172 , which has a crucial role in the autophagic response . The protective role of autophagy in cell growth inhibition by CP-31398 and RITA is supported by the finding that the AMPK inhibitor compound C or the autophagy inhibitors chloroquine or 3-methyladenine sensitize both pancreatic adenocarcinoma cell lines to the apoptotic response induced by p53-reactivating molecules .

Telomerase is not expressed in most normal human somatic cells but is active in stabilizing telomeres of certain self-renewing cell populations and most malignant cells , making the enzyme an appealing target for anticancer therapy . We describe here a novel cross-species approach to telomerase inhibition . Ectopic expression of the human telomerase catalytic reverse transcriptase component in murine cells inhibited endogenous murine telomerase activity . Using this approach , telomerase inhibition in immortal murine fibroblasts resulted in critical telomere shortening , leading to slowed proliferation , abnormal morphology , altered cell cycle , and telomere dysfunction with cytogenetic instability , followed by apoptotic cell death . Subpopulations of two telomerase-inhibited clones escaped widespread apoptosis , showing proliferative recovery in culture despite persistently inhibited telomerase activity with progressive telomere shortening and dysfunction . This study , by targeting immortal murine cells for telomerase inhibition , demonstrates the importance of telomerase to murine cell immortalization and telomere maintenance .

Although certain intermediates of glycolytic and oxidative metabolic pathways have been known to affect angiogenesis , the effect of citrate , which accumulates in certain tumors , on angiogenesis is not known . Therefore , the effect of citrate on angiogenesis was studied using different model systems . Increased vascularization in chorioallantoic membrane assay , increased endothelial sprouting in rat aortic rings , and increased expression of CD31 , E-selectin in endothelial cells suggested a possible proangiogenic effect of citrate . Upregulation of angiogenic factors such as vascular endothelial growth factor and fibroblast growth factor suggested that the effect of citrate involves modulation of expression of angiogenic growth factors . LY 294002 , an inhibitor of PI3K-Akt pathway , and wortmannin , an inhibitor of Akt pathway , reversed the effect of citrate in human umbilical vein endothelial cells . Citrate induced significant upregulation and activation of Akt in endothelial cells .

Individual susceptibility to aflatoxin-induced hepatocarcinogenesis may be modulated by both genetic and environmental factors affecting metabolism . A cross-sectional study was performed to evaluate determinants of the formation of aflatoxin covalently bound to albumin ( AFB1-albumin adducts ) . A total of 474 subjects who were free of liver cancer and cirrhosis and were initially selected as controls for previous case-control studies of aflatoxin-induced hepatocarcinogenesis in Taiwan , were employed in this study . Aflatoxin-albumin adducts were determined by competitive enzyme-linked immunosorbent assay , hepatitis B surface antigen and antibodies to hepatitis C virus by enzyme immunoassay , as well as genotypes of glutathione S-transferase M1-1 and T1-1 by polymerase chain reaction . The detection rate of AFB1-albumin adducts was significantly higher in males ( 42.5% ) than in females ( 21.6% ) ( multivariate-adjusted odds ratio=2.6 , 95% confidence interval=1.4-5.0 ) . The formation of detectable albumin adducts was moderately higher in hepatitis B surface antigen carriers ( 42.8% ) than in non-carriers ( 36.6% ) ( multivariate-adjusted odds ratio=1.4 , 95% confidence interval=1.0-2.1 ) . In addition , the detection rate of AFB1-albumin adducts tended to increase with the increasing number of null genotypes of glutathione S-transferase M1-1 and glutathione S-transferase T1-1 . In conclusion , this cross-sectional study has assessed the relative contributions of environmental exposure and host susceptibility factors in the formation of AFB1-albumin adducts in a well characterised Chinese adult population . This study further emphasises the necessity to reduce aflatoxin exposure in people living in an area endemic for chronic hepatitis B virus infection .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

We report a study to analyze the effect of these asymmetries when the replication machinery encounters alkylation-induced DNA adducts . The model system is an EBV-derived shuttle vector which replicates in synchrony with the host human cells and carries as marker gene the bacterial gpt gene . A preferential distribution of N-methyl-N-nitrosourea ( MNU)-induced mutations in the non transcribed DNA strand of the shuttle vector pF1-EBV was previously reported . The hypermutated strand was the leading strand . To test whether the different fidelity of DNA polymerases synthesizing the leading and the lagging strands might contribute to MNU-induced mutation distribution the mutagenesis study was repeated on the shuttle vector pTF-EBV which contains the gpt gene in the inverted orientation . We show that the base substitution error rates on an alkylated substrate are similar for the replication of the leading and lagging strands . Moreover , we present evidence that the fidelity of replication opposite O6-methylguanine adducts of both the leading and lagging strands is not affected by the 3 ' flanking base . The preferential targeting of mutations after replication of alkylated DNA is mainly driven by the base at the 5 ' side of the G residues .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

The predicted BcOS1p is highly homologous to osmosensor histidine kinase OS1p from Neurospora crassa including the N-terminal six tandem repeats of approximately 90 amino acids . Four dicarboximide-resistant isolates of B. cinerea ( Bc-19 , Bc-45 , Bc-682 , and Bc-RKR ) contained a single base pair mutation in their BcOS1 gene that resulted in an amino acid substitution in the predicted protein . In these resistant isolates , codon 86 of the second repeat , which encodes an isoleucine residue in sensitive strains , was converted to a codon for serine . The mutation of Botrytis field resistant isolates was located on the second unit of tandem amino acid repeats of BcOS1p , whereas the point mutations of the fifth repeat of OS1p confer resistance to both dicarboximides and phenylpyrroles and also osmotic sensitivity in Neurospora crassa . These results suggest that an amino acid substitution within the second repeat of BcOS1p is responsible for phenotypes of field resistant isolates ( resistant to dicarboximides but sensitive to phenylpyrroles , and normal osmotic sensitivity ) in B. cinerea .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

How cells identify DNA lesions and convert them to checkpoint-activating structures is a major question . We show that during repair of UV lesions in noncycling cells , Exo1-mediated processing of nucleotide excision repair ( NER ) intermediates competes with repair DNA synthesis . Impediments of the refilling reaction allow Exo1 to generate extended ssDNA gaps , detectable by electron microscopy , which drive Mec1 kinase activation and will be refilled by long-patch repair synthesis , as shown by DNA combing . We provide evidence that this mechanism maybe stimulated by closely opposing UV lesions , represents a strategy to redirect problematic repair intermediates to alternative repair pathways , and may also be extended to physically different DNA damages .

Therefore , genetic variation in DNA repair genes may contribute to susceptibility to CBP in the exposed population . Since benzene-induced DNA damages include DNA adducts , we hypothesized that the polymorphisms of ERCC1 ( Excision repair cross complementation group 1 ) and ERCC2/XPD ( Excision repair cross complementation group 2/xeroderma pigmentosum group D ) are associated with the risk of CBP . A case-control study involving 102 benzene-poisoned patients and 204 none-benzene-poisoned controls occupationally exposed to benzene was carried out in the Northeast region of China . The polymorphisms of codon 118 ( rs11615 ) and C8092A ( rs3212986 ) of ERCC1 , codon 751 ( rs13181 ) , 312 ( rs1799793 ) and 156 ( rs238406 ) of ERCC2/XPD were genotyped by TaqMan(®) Real-time PCR . The results showed that individuals carrying the ERCC1 codon 118 TT genotype had an increased risk of CBP ( OR(adj)=3.390 ; 95%CI : 1.393-8.253 ; P=0.007 ) comparing with its CC genotype . After stratified by smoking , gender and exposure duration we found that the increased risk of CBP associated with the ERCC1 codon 118 TT genotype confined to nonsmokers ( OR=3.214 ; 95% CI : 1.359-7.601 ; P=0.006 ) , female ( OR=3.049 ; 95% CI : 1.235-7.529 ; P=0.013 ) and exposure duration&gt ; 12 years ( OR=3.750 ; 95% CI : 1.041-13.513 ; P=0.035 ) . Since ERCC1 and ERCC2/XPD are both located on chromosome 19q13.3 , haplotype analysis of all 5 SNPs was also conducted . However no correlations between the risks of CBP and other genotypes or haplotypes were found . Therefore , our findings suggest an important role of ERCC1 codon 118 polymorphisms for a biomarker to CBP in the Chinese occupational population .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

This irreversible ' fail-safe mechanism ' requires p19(ARF) , p53 and the Retinoblastoma ( Rb ) family : upon their disruption , RAS(V12)-expressing cells fail to undergo senescence and continue to proliferate . Similarly , co-expression of oncogenes such as c-MYC or E1A rescues RAS(V12)-induced senescence . To identify novel genes that allow escape from RAS(V12)-induced senescence , we designed an unbiased , retroviral complementary DNA library screen . We report on the identification of DRIL1 , the human orthologue of the mouse Bright and Drosophila dead ringer transcriptional regulators . DRIL1 renders primary murine fibroblasts unresponsive to RAS(V12)-induced anti-proliferative signalling by p19(ARF)/p53/p21(CIP1) , as well as by p16(INK4a) . In this way , DRIL1 not only rescues RAS(V12)-induced senescence but also causes these fibroblasts to become highly oncogenic . Furthermore , DRIL1 immortalizes mouse fibroblasts , in the presence of high levels of p16(INK4a) . Immortalization by DRIL1 , whose product binds the pRB-controlled transcription factor E2F1 ( ref. 8 ) , is correlated with induction of E2F1 activity . Correspondingly , DRIL1 induces the E2F1 target Cyclin E1 , overexpression of which is sufficient to trigger escape from senescence . Thus , DRIL1 disrupts cellular protection against RAS(V12)-induced proliferation downstream of the p19(ARF)/p53 pathway .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;sustaining proliferative signaling" } ]

There are numerous causes potentially responsible for a relapse of the disease , one of them being extensive angiogenesis . The balance of at least two systems , VEGF VEGFR and Ang Tie , regulates vessel formation . The aim of this study was to determine the impact of surgery on the plasma levels of the main angiogenic factors during the first month after surgery in nonsmall cell lung cancer patients . The study group consisted of 37 patients with stage I nonsmall cell lung cancer . Plasma concentrations of Ang1 , Ang2 , sTie2 , VEGF , and sVEGF R1 were evaluated by ELISA three times : before surgical resection and on postoperative days 7 and 30 . The median of Ang2 and VEGF concentrations increased on postoperative day 7 and decreased on day 30 . On the other hand , the concentration of sTie2 decreased on the 7th day after resection and did not change statistically later on . The concentrations of Ang1 and sVEGF R1 did not change after the surgery .

Endothelial cell migration and proliferation are key components of tumor angiogenesis , and agents that target the microtubule cytoskeleton can interfere with these processes . In this study , the effect on endothelial cell functions of the microtubule-stabilizing drugs Taxotere and Taxol were evaluated in three in vitro assays : a chemokinetic migration assay , an angiogenesis factor-mediated chemotactic migration assay , and a three-dimensional Matrigel tubule formation assay , using rat fat pad endothelial cells ( RFPECs ) and/or human umbilical vein endothelial cells ( HUVECs ) . Taxotere was active in all three assays at concentrations that were not cytotoxic and did not inhibit endothelial cell proliferation . In the RFPEC chemokinetic migration and in vitro tubule formation assays , the IC50 values were approximately 10(-9) M for both Taxotere and Taxol . HUVEC migration , however , was more sensitive to Taxotere , with an observed IC50 of 10(-12) M in a chemokinetic assay . In a Boyden chamber assay , HUVEC chemotaxis stimulated by either of two angiogenic factors , thymidine phosphorylase or vascular endothelial growth factor , was inhibited by Taxotere with an IC50 of 10(-11) M and was ablated at 10(-9) M. Taxotere was also up to 1000-fold more potent than Taxol in inhibiting either chemokinetic or chemotactic migration . When the microtubule cytoskeleton was visualized using immunofluorescence staining of alpha-tubulin , there were no gross morphological changes observed in HUVECs or RFPECs treated with Taxotere at concentrations that inhibited endothelial cell migration but not proliferation . The effects of Taxotere on migration were associated with a reduction in the reorientation of the cell's centrosome , at concentrations that did not affect gross microtubule morphology or proliferation . Reorientation of the centrosome , which acts as the microtubule organizing center , in the intended direction of movement is a critical early step in the stabilization of directed cell migration . These data indicate that endothelial cell migration correlates more closely with changes in microtubule plasticity than with microtubule gross structure . The antiangiogenic activity of Taxotere in vivo was assessed in a Matrigel plug assay . In this assay , the angiogenic response to fibroblast growth factor 2 was inhibited in vivo by Taxotere with an ID50 of 5.4 mg/kg when injected twice weekly over a 14-day period , and angiogenesis was completely blocked in mice that received 10 mg/kg Taxotere . The in vivo data further suggested that Taxotere had selectivity for endothelial cell migration and/or microvessel formation because infiltration of inflammatory cells into the Matrigel plug was much less sensitive to inhibition by Taxotere . In conclusion , Taxotere is a potent and potentially specific inhibitor of endothelial cell migration in vitro and angiogenesis in vitro and in vivo .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis;tumor promoting inflammation" } ]

Results were measured using labelling indices ( LIs). p107 LIs surpassed the highest value in normal tissues in six of nine hyperplastic polyps , 54 of 60 adenomas , 144 of 198 primary cancers , 13 of 21 nodal foci and three of 10 hepatic foci. p107 LIs also apparently rose from normal through hyperplasia and adenoma to early carcinoma . However , they declined in liver-metastatic foci , and in primary cancers showing large size , mucinous type , venous invasion , lymphatic invasion , poorly differentiated type , deep invasion , lymph-nodal metastasis , hepatic metastasis or advanced stage . Low p107 LIs were also linked to a poor survival , particularly in stage-III patients . As the p107 LI gradually rose , the CDK2 ( in primary cancers only ) , cyclin A , cyclin E and Ki67 LIs were elevated concurrently-in both adenomas and primary cancers . Thus , in colorectal tumours , p107 expression rises abnormally and gradually during carcinogenesis and then falls during invasion , and thereby probably perturbs the cell-cycle control and promotes carcinogenesis and invasion .

The immune system plays a major role in the fight against SCC , however , little is known about the local inflammatory response in SCC at all . We analyzed quantity and quality of the perineoplastic inflammatory SCC microenvironment in immunocompetent patients and immmunosuppressed OTRs . RNA expression profile of SCC patients was analyzed for 8 different sets of genes relating to Th1 versus Th2 response using Gene Set Enrichment Analysis . SCC from immunocompetent patients and OTRs were analyzed by real-time polymerase chain reactions for CD4 , CD8 , TBET , GATA-3 , FOXP3 , RORC , IFN-gamma , IL-4 , TGF-beta , IL-10 , and IL-17A mRNA expression . Immunohistochemistry was carried out in SCC for CD3 , CD4 , CD8 , and FOXP3 expression . Considerable inflammation was seen in both patient groups . SCC in immunocompetent patients and OTRs was associated with a mixed Th1 and Th2 gene expression signature . CD4(+) mRNA was diminished in immunosuppression . Skin adjacent to SCC in OTRs showed Th2 expression pattern as compared with immunocompetent patients . T-BET and IFN-gamma mRNA expression were decreased in the OTR group . Although Th17-weighted inflammation was unchanged , IL-17A mRNA level was markedly decreased with immunosuppression . Regulatory T cells , characterized by FOX-P3 and TGF-beta mRNA level , were decreased in OTRs . Our findings support the hypothesis that nontumor-bearing skin adjacent to SCC in OTRs is not necessarily normal and that the local microenvironment may contribute to a field effect contributing to higher recurrence rates and more aggressive behavior observed in these patients .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation;avoiding immune destruction" } ]

The expression pattern of MRGD in clinical samples was also analyzed . We found that overexpression of MRGD in NIH3T3 induced focus formation and multi-cellular spheroid formation , and promoted tumors in nude mice . In other words , overexpression of MRGD in NIH3T3 induced the loss of contact inhibition , anchorage-independent growth and in vivo tumorigenesis . Furthermore , it was found that the ligand of MRGD , beta-alanine , enhanced spheroid formation in MRGD-expressing NIH3T3 cells .

In human cervical carcinoma cells , RNAi-mediated CS knockdown induced morphological changes characteristic of the epithelial-mesenchymal transition ( EMT ) . This switch accelerated cancer cell metastasis and proliferation in in vitro assays and in vivo tumor xenograft models . Notably , CS knockdown cells exhibited severe defects in respiratory activity and marked decreases in ATP production , but great increases in glycolytic metabolism . This malignant progression was due to activation of EMT-related regulators ; altered energy metabolism resulted from deregulation of the p53/TIGAR and SCO2 pathways . This phenotypic change was completely reversed by p53 reactivation via treatment with proteasome inhibitor MG132 or co-knockdown of E3 ligase HDM2 and partially suppressed by ATP treatment . This study directly links the Warburg effect to tumor malignancy via induction of the EMT phenotype .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;cellular energetics" } ]

As such , there is a need for alternative methods for treating menopausal symptoms . To determine the influence of one such alternative , black cohosh ( Cimicifuga racemosa [ CR] ) , on estrogen-dependent mammary cancers , we conducted an in vitro investigation of the effect of an isopropanolic CR-extract on the proliferation of estrogen receptor-positive breast cancer cells . The experiments were performed using the human breast adenocarcinoma ( MCF-7 ) cell test system , an established in vitro model for estrogen-dependent tumors . The influence of CR-extract on the proliferation of the MCF-7 cells was determined by measuring the incorporation of radioactively labeled thymidine . Under estrogen-deprived conditions , the CR-extract ( 10(-3)-10(-5) dilutions ) significantly inhibited MCF-7 cell proliferation . Additionally , application of the CR-extract inhibited estrogen-induced proliferation of MCF-7 cells . Moreover , the proliferation-inhibiting effect of tamoxifen was enhanced by the CR-extract . Such data that suggest a non-estrogenic , or estrogen-antagonistic effect of CR on human breast cancer cells lead to the conclusion that CR treatment may be a safe , natural remedy for menopausal symptoms in breast cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

However , the mechanisms involved have not been fully elucidated in prostate cancer ( PCa ) cells , which differ dramatically from normal cells in their zinc handling ability . Here , we studied the effects of the ionophore Zn-pyrithione ( ZP ) and the chelator N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine ( TPEN ) . Both compounds induced cell death at micromolar concentrations when incubated with androgen-dependent ( LNCaP ) , androgen-independent ( PC3 , DU145 ) and androgen-sensitive ( C4-2 ) PCa cell-lines . Compared to PCa cells , RWPE1 prostate epithelial cells were less sensitive to ZP and more sensitive to TPEN , but total cellular zinc levels were changed similarly . ZnSO4 enhanced the toxicity of ZP , but inhibited the effects of TPEN as expected . The morphological/biochemical responses to ZP and TPEN differed . ZP decreased ATP levels and stimulated ERK , AKT and PKC phosphorylation . DNA laddering was observed only at low doses of ZP but all doses of TPEN . TPEN activated caspase 3/7 and induced PARP-cleavage , DNA-fragmentation , ROS-formation and apoptotic bodies . PKC and ERK-pathway inhibitors , and antioxidants protected against ZP-induced but not TPEN-induced death . Inhibitors of MPTP-opening protected both . Cell death in response to TPEN ( but not ZP ) was diminished by a calpain inhibitor and largely prevented by a caspase 3 inhibitor . Overall , the results indicated primarily a necrotic cell death for ZP and an apoptotic cell death for TPEN . The enhanced sensitivity of PCa cells to ZP and the apparent ability of ZP and TPEN to kill quiescent and rapidly dividing cells in a p53-independent manner suggest that ZP/TPEN might be used to develop adjunct treatments for PCa .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

We compared multiple levels of regulation of histone gene expression during 3T3-L1 pre-adipocyte differentiation . Confluent cells induced to differentiate by treatment with insulin , dexamethasone , and isobutylmethylxanthine initially exhibited an increased proliferative response compared with cells given serum alone . This initial differentiation response was associated with a twofold increase in both histone gene transcription and cellular histone mRNA levels , as well as with enhanced sequence-specific binding of nuclear factors to the proximal cell-cycle-regulatory element of the H4 histone promoter . Transforming growth factor beta 1 , an inhibitor of 3T3-L1 differentiation , increased both the percentage of proliferating cells and the cellular levels of histone mRNA when given in addition to serum stimulation , but no enhancement of these parameters was observed upon addition of TGF beta 1 to the differentiation treatment . Interestingly , although TGF beta 1 enhanced binding of nuclear factors to the proximal cell cycle regulatory element of the histone promoter , these protein/DNA interactions were not associated with an increase in histone transcription . Our results are consistent with the down-regulation of histone gene expression at confluency being controlled primarily at the post-transcriptional level , in contrast to an increased involvement of transcriptional down-regulation at the onset of differentiation .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

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

It was suggested that the up-regulation of IL-10 production and IL-10 receptor ( IL-10R ) expression would be part of the transition from primary tumor to metastatic phenotype and that IL-10 , besides its immunosuppressive activity , may act as a growth factor for metastatic L-TACB cells . The treatment of L-TACB-bearing rats with a single low-dose cyclophosphamide decreased IL-10 production , reverted immunosuppression and induced the immunologic rejection of tumor metastasis without any effect on primary tumor growth . Our current aim was to investigate the effects of cyclophosphamide on the expression of IL-10 and IL-10R on primary and metastatic L-TACB cells . Considering that cyclophosphamide is a prodrug , we used mafosfamide , a compound that yields in vitro the same active metabolites as cyclophosphamide does in vivo . Mafosfamide induced down-regulation of IL-10 production and IL-10R expression on metastatic cells and , concomitantly , inhibited metastatic cell proliferation . We suggest that mafosfamide would inhibit the regulatory loop mediated by the IL-10/IL-10R system and , as a consequence , metastatic cell proliferation . These results may have a considerable impact on the design of new therapies for metastatic lymphomas .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;avoiding immune destruction" } ]

Targeting the glycolysis pathway has been explored as an anti-cancer therapeutic strategy to eradicate cancer based on this fundamental biochemical property of cancer cells . Oncoproteins such as Akt and c-Myc regulate cell metabolism . Accumulating studies have uncovered various molecular mechanisms by which oncoproteins affect cellular metabolism , raising a concern as to whether targeting glycolysis will be equally effective in treating cancers arising from different oncogenic activities . Here , we established a dual-regulatable FL5.12 pre-B cell line in which myristoylated Akt is expressed under the control of doxycycline , and c-Myc , fused to the hormone-binding domain of the human estrogen receptor , is activated by 4-hydroxytamoxifen . Using this system , we directly compared the effect of these oncoproteins on cell metabolism in an isogenic background . Activation of either Akt or c-Myc leads to the Warburg effect as indicated by increased cellular glucose uptake , glycolysis , and lactate generation . When cells are treated with glycolysis inhibitors , Akt sensitizes cells to apoptosis , whereas c-Myc does not . In contrast , c-Myc but not Akt sensitizes cells to the inhibition of mitochondrial function . This is correlated with enhanced mitochondrial activities in c-Myc cells . Hence , although both Akt and c-Myc promote aerobic glycolysis , they differentially affect mitochondrial functions and render cells susceptible to the perturbation of cellular metabolic programs .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

The migration of neoplastic cells during the metastatic process may be affected by various extracellular factors , including chemoattractants , haptotactic signals , electric fields , substrate anisotropy , and cell-to-cell contacts . We examined the effect of homotypic collisions and heterotypic interactions with normal human skin fibroblasts on the motile activity of Walker carcinosarcoma cells . It was found that Walker carcinosarcoma cells moving in a dense population neither show contact inhibition of movement when colliding with one another nor increase their motile activity as a result of contact stimulation of motility . On the other hand , when plated onto the surface of aligned fibroblasts , Walker carcinosarcoma cells migrated mainly along the long axes of underlying fibroblasts as a result of contact guidance . The directional character of movement ( but not the speed of migration ) of Walker carcinosarcoma cells on the surface of aligned fibroblasts was completely effaced by RGD-containing synthetic peptide at a concentration of 1 mg/ml but not by 5 microM verapamil ( selective voltage-gated calcium channel inhibitor ) or 10 microM gadolinium chloride ( non-specific blocker of mechanosensitive ion channels ) . The suppression of directional character of migration of tumour cells by RGD-containing peptide was associated with the decrease in the amount of fibronectin macromolecules attached to fibroblasts . This suggests that alignment and anisotropic distribution of fibronectin macromolecules may be responsible for contact guidance of tumour cells moving on the surface of fibroblasts .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

In order to understand how this effect is mediated , experiments were performed that addressed a possible influence of carnosine on energy metabolism . METHODS Cells from the glioma line T98G and primary cultured cells from human malignant glioma were cultivated in the presence of carnosine and inhibitors of cellular energy metabolism . As a specific inhibitor for anaerobic glycolysis , oxamate , and as an inhibitor for mitochondrial oxidative phosphorylation , potassium cyanide , were used , and the influence on ATP production was determined using cell-based assays . RESULTS The experiments identified glycolysis as crucial for ATP production in gliomas . In addition , ATP production by mitochondrial activity did not significantly contribute to ATP production and carnosine was identified to be an inhibitor of the vital anaerobic glycolysis . DISCUSSION Carnosine might be considered as a potential drug for the treatment of malignant glioma or other tumors since it inhibits the glycolytic energy metabolism that is crucial for cancer cells and malignant gliomas as shown in the current study . This is especially interesting since the dipeptide is a naturally occurring substance that should be well tolerated .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

Telomerase activity is repressed in somatic cells and tissues but is activated in immortal and malignant cells . We evaluated telomerase activity in seven primary malignant mesothelioma biopsies and matched lung specimens and 20 mesothelioma cell lines and eight corresponding primary tumor cultures . All the tumor biopsies , and nearly all primary cell mesothelioma cultures and cell lines were telomerase positive . The findings in cell lines paralleled those observed in primary cultures in cases where paired samples were available . Next , we found that SV40 , a DNA tumor virus present in approximately 50% of mesothelioma biopsies in the USA , induced telomerase activity in primary human mesothelial cells , but not in primary fibroblasts . Telomerase activity became detectable as early as 72 h following wild-type ( strain 776 ) SV40 infection , and a clear DNA ladder was detectable 1 week after infection . The amount of telomerase activity increased during passage in cell culture and appeared to parallel increases in the cellular amounts of the SV40 large T-antigen . Thus , SV40 infection leads to telomerase activity before the infected mesothelial cells become transformed and immortalized . SV40 infection of human fibroblasts did not cause detectable telomerase activity . We also determined that the SV40 small t-antigen ( tag ) plays an important role in inducing telomerase activity because this activity was undetectable or minimal in mesothelial cells infected and/or transformed by SV40 tag mutants . Asbestos alone did not induce telomerase activity , and asbestos did not influence telomerase activity in mesothelial cells infected with SV40 . Induction of telomerase activity by SV40 may be related to the very high rate of mesothelial cell immortalization that is characteristically associated with SV40 infection of mesothelial cells .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

We previously reported that tumors implanted in TNF receptor-deficient ( Tnfr-/- ) mice are spontaneously rejected ; however , the molecular mechanisms underlying this rejection are unclear . Here we report that TNF signaling drives the peripheral accumulation of myeloid-derived suppressor cells ( MDSCs ) . MDSCs expand extensively during inflammation and tumor progression in mice and humans and can enhance tumor growth by repressing T cell-mediated antitumor responses . Peripheral accumulation of MDSCs was drastically impaired in Tnfr-/- mice . Signaling of TNFR-2 , but not TNFR-1 , promoted MDSC survival through upregulation of cellular FLICE-inhibitory protein ( c-FLIP ) and inhibition of caspase-8 activity . Loss of TNFRs impaired the induction of MDSCs from bone marrow cells , but this could be reversed by treatment with caspase inhibitors . These results demonstrate that TNFR-2 signaling promotes MDSC survival and accumulation and helps tumor cells evade the immune system .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

METHODOLOGY/PRINCIPAL FINDINGS To address intertumoral heterogeneity we investigated non-microdissected tumor tissue of 106 gliomas representing 51 recurrent tumors . To address intratumoral heterogeneity a set of 16 gliomas representing 7 tumor pairs with at least one recurrence , and 4 single mixed gliomas were investigated by microdissection of distinct oligodendroglial and astrocytic tumor components . All tumors and tumor components were analyzed for allelic loss of 1p/19q ( LOH 1p/19q ) , for TP53- mutations and for R132 mutations in the IDH1 gene . The investigation of non-microdissected tumor tissue revealed clonality in 75% ( 38/51 ) . Aberrant molecular alterations upon recurrence were detected in 25% ( 13/51). 64% ( 9/14 ) of these were novel and associated with tumor progression . Loss of previously detected alterations was observed in 36% ( 5/14 ) . One tumor pair ( 1/14 ; 7% ) was significant for both . Intratumoral clonality was detected in 57% ( 4/7 ) of the microdissected tumor pairs and in 75% ( 3/4 ) of single microdissected tumors. 43% ( 3/7 ) of tumor pairs and one single tumor ( 25% ) revealed intratumoral heterogeneity . While intratumoral heterogeneity affected both the TP53- mutational status and the LOH1p/19q status , all tumors with intratumoral heterogeneity shared the R132 IDH1- mutation as a common feature in both their microdissected components . CONCLUSIONS/SIGNIFICANCE The majority of recurrent gliomas are of monoclonal origin . However , the detection of divertive tumor cell clones in morphological distinct tumor components sharing IDH1- mutations as early event may provide insight into the tumorigenesis of true mixed gliomas .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

However , little is known about the apoptosis-inducing effects of paclitaxel and pirarubicin on human osteosarcoma MG-63 cells . METHODS The effects of paclitaxel and pirarubicin on cell cycle arrest and apoptosis were studied in MG-63 cells using flow cytometry . PCNA , Bcl-2 , Bax , cyclin D1 and cyclin E expression was assessed by Western blotting . RESULTS Paclitaxel and pirarubicin caused G2/M and G0/G1 cell cycle arrest in MG-63 cells , respectively . Apoptosis of MG-63 cells mediated by paclitaxel was dependent on treatment duration . Interestingly , in cells treated with pirarubicin , apoptosis was related to treatment duration at concentrations of 10(2)-10(3) nM , whereas the effect of treatment duration was less marked at concentrations >10(4)-10(5) nM . Furthermore , paclitaxel and pirarubicin suppressed the expression of PCNA , cyclin D1 , cyclin E and Bcl-2 , and increased Bax expression . CONCLUSION These results suggest that the G2/M or G0/G1 cell cycle arrest and apoptosis induced by paclitaxel and pirarubicin are Bcl-2/Bax dependent , suggesting favorable effects of combination therapy with paclitaxel and pirarubicin in the treatment of osteosarcoma .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling;resisting cell death" } ]

Our previous study has shown that GA monomer could inhibit the growth of Hep-2 significantly and induce the fragmentation of the chromosomal DNA . To further assess the antitumor potential and turn it into a candidate new antitumor drug , the antitumor mechanism of GA was investigated . METHOD The cytotoxicity and antitumor effect of GA monomer were assayed by MTT colorimetric assay with nontumorogenic MC-3T3-E1 as well as tumorogenic Hep-2 and Tac8113 cell lines . The effect of GA monomer on the proliferation of tumor cell lines was analyzed with MTT colorimetric and CFSE labeled assay . Cell cycle distribution and measurement of the percentage of apoptotic cells were performed by flow cytometry following stained with propidium iodide , annexin V-FITC . The expression of apoptotic proteins Bcl-2 , Bax and caspase-3 was analyzed with Western blot . RESULT GA only inhibited the growth of tumorogenic cell lines in a both dose- and time-dependent manner . Tumor cells were treated with GA for 72 h , 70.53 ± 4.54% Hep-2 and 63.5 ± 7.2% Tca8113 cells were retarded at GO/G1 phase , and the percentage of apoptosis was 40.4 ± 1.58 and 38.4 ± 1.7% , respectively . GA-treated activated caspase-3 downregulated the expression of anti-apoptotic Bcl-2 protein and upregulated the expression of pro-apoptotic Bax protein , eventually leading to a decrease in the Bcl-2/Bax ratio in tumor cells .

Here we show that the expression of Jagged1 , a ligand for canonical Notch signaling , was restricted to enteroendocrine cells or undetectable in the mucosa of the human small and large intestine , respectively . In contrast , increased expression characterized half of human colon tumors , although not all tumors with elevated Wnt signaling displayed elevated Jagged1 . Increased Jagged1 was also present in intestinal tumors of Apc(1638N/+) and Apc(Min/+) mice , but to a higher level and more frequently in the former , and in 90% of mouse tumors Notch signaling was elevated when Jagged1 was elevated . In the human HT29Cl16E colonic carcinoma cell line , induction of goblet cell differentiation by contact inhibition of growth depended on the loss of Jagged1-mediated Notch activation , with signaling through Notch1 and Notch2 acting redundantly .

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

We hypothesized that in addition to the alloantigen-driven anti-tumour response , disruption of the immunological microenvironment within the tumour is responsible for its elimination after allo-HCT . We observed that induction of graft-versus-host disease ( GvHD ) significantly reduced the abundance of luc(+) FoxP3(+) regulatory T ( Treg ) cells in the tumour tissue , which is indicative of impaired or over-ridden tumour recruitment signals towards Treg cells . Analysis of the intestines and liver revealed chemokines and purine nucleotides as candidates for attracting Treg to these sites of inflammation . Despite its expression on tissue-residing Treg cells , the chemokine receptor CCR3 was not critical for Treg-cell function following allo-HCT . Extracellular ATP can attract immune cells via P2Y2 . P2Y2 was found to be expressed on Treg cells , and we found a partial reduction of GvHD prevention when P2Y2(-/-) rather than P2Y2(+/+) Treg cells were given . Exogenous local inflammation reduced Treg-cell accumulation in the tumour , suggesting a potential clinical approach to prevent Treg-cell-mediated tumour escape . In conclusion , we demonstrate that GvHD-related inflammation reduced Treg-cell numbers at the tumour sites , which may in turn help to explain the observation that patients with GvHD have a lower risk of tumour relapse .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

One of these , ATM , the product of the gene mutated in the human genetic disorder ataxia-telangiectasia ( A-T ) , recognises double strand breaks in DNA caused by ionizing radiation and radiomimetic chemicals . In order to study DNA damage recognition and the abnormalities of genome instability and cancer predisposition that occur in A-T patients , we generated a mouse model expressing a mutant form of Atm corresponding to a common human mutation . In this model , a 9 nucleotide in-frame deletion was introduced into the Atm gene and has been designated Atm-Delta SRI . These animals had a longer lifespan than Atm gene disrupted mice ( Atm(-/-) ) and they developed less thymic lymphomas . A characteristic of the lymphomas appearing in Atm-Delta SRI mice was an increased rate of apoptosis compared to the corresponding tumours in Atm(-/-) mice . Increased expression of FasL in these tumours may account for the higher levels of apoptosis . These results demonstrate that expression of mutant Atm in mice gives rise to phenotypic differences compared to Atm(-/-) mice and has implications for heterogeneity described in the human syndrome .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;resisting cell death" } ]

HOX11 is also leukaemogenic , both through its clinical association with childhood T-cell acute lymphoblastic leukaemia , and its ability to immortalize other haematopoietic cell lineages experimentally . To examine the pathological role of HOX11 in tumorigenesis , we constitutively expressed HOX11 cDNA in J2E murine erythroleukaemic cells , which are capable of terminal differentiation . Enforced HOX11 expression was found to induce a profound alteration in J2E cellular morphology and differentiation status . Our analyses revealed that HOX11 produced clones with a preponderance of less differentiated cells that were highly adherent to plastic . Morphologically , the cells overexpressing HOX11 were larger and had decreased globin levels , as well as a reduction in haemoglobin synthesis in response to erythropoietin ( EPO ) . Immunocytochemical analysis confirmed the immature erythroid phenotype imposed by HOX11 , with clones transfected with HOX11 demonstrating expression of the c-Kit stem cell marker , while retaining EPO receptor expression . Taken together , these results show that HOX11 alters erythroid differentiation , favouring a less mature progenitor-like stage . This supports the notion that disrupted haematopoietic cell differentiation is responsible for pre-leukaemic immortalization by the HOX11 oncoprotein .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

To study its biologic function in myeloid cells , dominant-negative PPARγ ( dnPPARγ ) was overexpressed in a myeloid-specific bitransgenic mouse model . In this bitransgenic system , overexpression of the dnPPARγ-Flag fusion protein in myeloid-lineage cells abnormally elevated frequencies and total numbers of IL-7Rα(-)Lin(-)c-Kit(+)Sca-1(-) , Lin(-)/Scal(+)/c-Kit(+) , common myeloid , and granulocyte-monocyte progenitor populations in the BM. dnPPARγ overexpression led to up-regulation of IL-1β , IL-6 , and TNFα in the blood plasma . As a result , CD11b(+)Ly6G(+) cells were systemically increased in association with activation of Stat3 , NF-κB , Erk1/2 , and p38 molecules . Myeloid-derived suppressor cells ( MDSCs ) inhibited the proliferation and lymphokine production of wild-type CD4+ T cells in vitro . CD4+ T cells from doxycycline-treated bitransgenic mice displayed reduced proliferation and lymphokine release . Both CD4+ and CD8+ T-cell populations were decreased in doxycycline-treated bitransgenic mice . Multiple forms of carcinoma and sarcoma in the lung , liver , spleen , and lymph nodes were observed in doxycycline-treated bitransgenic mice . BM transplantation revealed that a myeloid-autonomous defect was responsible for MDSC expansion , immunosuppression , and tumorigenesis in these mice . These studies suggest that anti-inflammatory PPARγ in myeloid-lineage cells plays a key role in controlling pro-inflammatory cytokine synthesis , MDSC expansion , immunosuppression , and the development of cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;tumor promoting inflammation" } ]

Mammalian cells mount a coordinated response to DSBs with the aim of appropriately repair the DNA damage . Indeed , failure of the DNA damage response ( DDR ) can lead to the development of cancer-prone genetic diseases . The identification and development of drugs targeting proteins involved in the DDR is even more investigated , as it gives the possibility to specifically target cancer cells . Indeed , the administration of DNA repair inhibitors could be combined with chemo- and radiotherapy , thus improving the eradication of tumor cells . Here , we provide an overview about DSBs damage response , focusing on the role of the DSBs repair mechanisms , of chromatin modifications , and of the cancer susceptibility gene BRCA1 which plays a multifunctional role in controlling genome integrity . Moreover , the most investigated DSBs enzyme inhibitors tested as potential therapeutic agents for anti-cancer therapy are reported .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]
