Because tamoxifen is known to alter ovary function in human patients and in rats , the present study was aimed at exploring whether tamoxifen could alter Ca(2+) movement in Chinese hamster ovary ( CHO-K1 ) cells . Cytosolic free-Ca(2+) levels in populations of cells have been explored by using fura-2 as a fluorescent Ca(2+) indicator . Tamoxifen at concentrations above 1 micro M increased [ Ca(2+)](i) in a concentration-dependent manner with an EC(50) value of 8 micro M. The Ca(2+) signal was reduced by removing extracellular Ca(2+) , but was not affected by nifedipine , verapamil , diltiazem or ICI 182,780 ( an estrogen receptor antagonist ) . Pretreatment with 1 micro M thapsigargin ( an endoplasmic reticulum Ca(2+) pump inhibitor ) to deplete the endoplasmic reticulum Ca(2+) abolished 10 micro M tamoxifen-induced Ca(2+) release . Neither inhibition of phospholipase C with 2 micro M U73122 nor depletion of ryanodine-sensitive Ca(2+) stores with 50 micro M ryanodine affected tamoxifen-induced Ca(2+) release . Cell proliferation assays using ELISA revealed that overnight incubation with 5-10 micro M tamoxifen inhibited cell proliferation by 20% , and 20 micro M tamoxifen killed all cells . Together , the results suggest that , in CHO-K1 cells , tamoxifen induced a [ Ca(2+)](i) increase by causing store-Ca(2+) release from the endoplasmic reticulum in an phospholipase C-independent manner , and by inducing Ca(2+) influx . The action of tamoxifen appears to be dissociated from estrogen receptor activation . Longer incubation with tamoxifen ( >5 micro M ) was cytotoxic .\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

In addition , truncated Notch1 alleles could be associated with 10% of all cases of human T lymphoblastic leukemia and , when introduced into mouse bone marrow stem cells , cause T-cell neoplasms . However , functional links between the abundant expression of intact Notch1 and oncogenesis are still lacking . Here we show that Notch1 is highly expressed in B- and T-cell-derived tumor cells of Hodgkin and anaplastic large cell lymphoma . We demonstrate a novel mechanism for the oncogenic capacity of Notch1 by showing that the interaction between intact Notch1 on tumor cells and its ligand Jagged1 dramatically induces proliferation and inhibition of apoptosis in vitro . We further provide evidence that in Hodgkin and anaplastic large cell lymphoma , Jagged1 is expressed in malignant and in bystander cells colocalizing with Notch1-positive tumor cells . Notch1 signaling may therefore be activated in tumor cells by Jagged1 through homotypic or heterotypic cell-cell interactions , and it seems likely that these interactions contribute to lymphomagenesis in vivo . Thus , our data suggest that activated Notch1 signaling plays an important role in the pathobiology of Hodgkin and anaplastic large cell lymphoma and that it might be a potential new target for treatment .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling" } ]

However , the molecular mechanisms of RA actions on cancer cells remain diverse . In this study , the dose-dependent inhibition of RA on DU145 cell proliferation was identified . Interestingly , RA treatment triggered p35 cleavage ( p25 formation ) and Cdk5 overactivation , and all could be blocked by Calpain inhibitor , Calpeptin ( CP ) . Subsequently , RA-triggered DU145 apoptosis detected by sub-G1 phase accumulation and Annexin V staining could also be blocked by CP treatment . Furthermore , RA-triggered caspase 3 activation and following Cdk5 over-activation were destroyed by treatments of both CP and Cdk5 knockdown . In conclusion , we report a new mechanism in which RA could cause apoptosis of androgen-independent prostate cancer cells through p35 cleavage and Cdk5 over-activation . This finding may contribute to constructing a clearer image of RA function and bring RA as a valuable chemoprevention agent for prostate cancer patients .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death" } ]

This could be relevant because the type of DNA damage could have different effects . Semen samples were classified attending their clinical status : 25 fertile donors and 20 RPL patients with at least two unexplained first trimester miscarriages . SDF was analysed using alkaline and neutral Comet assay , SCD test and pulsed-field gel electrophoresis ( PFGE ) , and ROC analysis including data from 105 more infertile patients ( n = 150 ) was performed to establish predictive threshold values . SDF for alkaline and neutral Comet , and the SCD test was analysed in these categories of individuals . Data revealed the presence of two subgroups within fertile donors . The values obtained were 21.10±9.13 , 23.35±10.45 and 12.31±4.31 , respectively , for fertile donors with low values for both ssSDF and dsSDF ; 27.86±12.64 , 80.69±12.67 and 12.43±5.22 , for fertile donors with low ssSDF and high dsSDF ; and 33.61±15.50 , 84.64±11.28 and 19.28±6.05 , for unexplained RPL patients , also showing a low ssSDF and high dsSDF profile . This latter profile was seen in 85% of unexplained RPL and 33% of fertile donors , suggesting that it may be associated to a male risk factor for undergoing RPL . ROC analysis regarding recurrent miscarriage set the cut-off value at 77.50% of dsDNA SDF . PFGE for low ssSDF and high dsSDF profile samples and positive controls treated with DNase , to induce dsDNA breaks , showed a more intense band of about 48 kb , which fits the toroid model of DNA compaction in sperm , pointing out that some nuclease activity may be affecting their sperm DNA in RPL patients . This work identifies a very specific SDF profile related to the paternal risk of having RPL .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation" } ]

However , the mechanisms of tumor cell death induced by HA and HB are still unclear . In this study , we attempt to elucidate the photodynamic effects of HA and HB compounds in poorly differentiated ( CNE2 ) and moderately differentiated ( TW0-1 ) human nasopharyngeal carcinoma ( NPC ) cells as well as human mucosal colon ( CCL-220.1 ) and bladder ( SD ) cells . Using these cell lines we investigated few hall marks of apoptotic commitments in a drug and light dose dependent manner . Tumor cells photoactivated with HA and HB showed cell size shrinkage and an increase in the sub-diploid DNA content . A loss of membrane phospholipid asymmetry associated with apoptosis was induced by all tumor cell lines as evidenced by the externalization of phosphatidylserine . Western blot analysis of poly ( ADP-ribose ) polymerase , a caspases substrate , showed the classical cleavage pattern ( 116 to 85kDa ) associated with apoptosis in HA and HB-treated cell lysates . In addition , PARP cleavage was blocked by using tetrapepdide caspases inhibitors such as DEVD or z-VAD . These results demonstrate that tumor cell death induced by HB and HA is mediated by caspase proteases . This study also identifies both colon and bladder cells were more sensitive cell lines than NPC ( CNE2 and TWO-1 ) cell lines .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death" } ]

Accumulating evidence indicates that autophagy plays a significant role in response to cancer therapy . However , the role of autophagy in oxaliplatin-induced cell death remains to be clarified . In this study , we showed that oxaliplatin induced cell death and autophagy in Caco-2 colorectal cancer cells . The suppression of autophagy using either pharmacologic inhibitors ( 3-methyladenine , bafilomycin A1 ) or RNA interference in essential autophagy genes ( ATG5 or Beclin1 ) enhanced the cell death and reactive oxygen species ( ROS ) production induced by oxaliplatin in Caco-2 cells . Blocking oxaliplatin-induced ROS production by using ROS scavengers ( NAC or Tiron ) decreased autophagy . Furthermore , numerous dilated endoplasmic reticula ( ER ) were present in oxaliplatin-treated Caco-2 cells , and blocking ER stress by RNA interference against candidate of metastasis-1 ( P8 ) and C/EBP-homologous protein ( CHOP ) decreased autophagy and ROS production . Taken together , these data indicate that oxaliplatin activates autophagy as a cytoprotective response via ER stress and ROS in human colorectal cancer cells .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death;tumor promoting inflammation" } ]

We attempted to evaluate the markers of oxidative stress , antioxidant mechanism and the inflammatory pathway in patients with breast cancer . METHODS This study was carried out in departments of Biochemistry and Surgery , Maulana Azad Medical College and associated Hospitals , New Delhi , India . A total of 60 cases of carcinoma of the breast and 60 healthy controls were included in the study . The parameters that were assayed include markers of oxidative stress-conjugated dienes , thiobarbitone reactive substances ( TBARS ) , antioxidants-superoxide dismutase ( SOD ) , catalase ( CAT ) , glutathione peroxidase ( GPx ) , glutathione ( GSH ) and markers of inflammation-interleukin-6(IL-6) and ferritin . RESULTS There was a significant decline in the antioxidant levels and a significant rise in oxidant levels in patients with carcinoma of the breast , compared to controls . The inflammatory markers-IL-6 and ferritin-were also significantly higher in patients with breast cancer . A significantly positive correlation was observed between the IL-6 levels and conjugated dienes with the stage of breast carcinoma ; whilst a significantly negative correlation was observed between the levels of conjugated dienes and superoxide dismutase and superoxide dismutase levels with the disease staging . CONCLUSIONS This study underlines the interplay between inflammatory pathways and oxidative stress in the pathogenesis of breast cancer . MINI ABSTRACT : An intense research is underway to identify the possible risk factors and the molecular mechanisms involved in pathogenesis of breast cancer .

In contrast , aFGF or bFGF enhancement of C3 cell thymidine incorporation was about 5% of that of T5 cells , and effects were principally mitogen concentration independent . Saturation analyses and cross-linking studies established that both C3 and T5 cells contained high-affinity FGF receptors of 120 and 145 kilodaltons and that receptor content and Kd of C3 and T5 cells were comparable. aFGF or bFGF stimulation of T5 cell thymidine incorporation profoundly decreased as cell plating density was reduced from 1.5 x 10(5) to 1.0 x 10(4) cells/well . The modest response of C3 cells to either aFGF or bFGF also decreased as cell plating density was reduced . Because heparin preserves FGF biological activity and enhances bFGF binding to high-affinity FGF receptors , we examined the effect of heparin on FGF stimulation of C3 cell thymidine incorporation . We found that changes in cell plating density and/or medium heparin concentration had variable , inconsistent effects . These were C3 cell plating density associated and included inhibition or modest enhancement of FGF effects . Binding analyses established that high-affinity bFGF binding of C3 and T5 cells immediately prior to assessing FGF-stimulated thymidine incorporation was comparable and independent of cell plating density , implying that C3 cell FGF insensitivity was not attributable to differences in C3 and T5 cell FGF receptor content at the time of mitogen stimulation.(ABSTRACT TRUNCATED AT 250 WORDS )\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

However , immune responses to such antigens are often muted or lacking due to the antigens being recognized as \" self \" , and further complicated by the tumour environment and regulation of immune cells within . In an effort to circumvent the lack of immune responses to tumour antigens , we have devised a strategy to develop potential synthetic immunogens . The strategy , termed mirror image phage display , is based on the concept of molecular mimicry as demonstrated by the idiotype/anti-idiotype paradigm in the immune system . Here as ' proof of principle ' we have selected molecular mimics of the well-characterised tumour associated antigen , the human mucin1 protein ( MUC1 ) from two different peptide phage display libraries . The putative mimics were compared in structure and function to that of the native antigen . Our results demonstrate that several of the mimic peptides display T-cell stimulation activity in vitro when presented by matured dendritic cells . The mimic peptides and the native MUC1 antigenic epitopes can cross-stimulate T-cells . The data also indicate that sequence homology and/or chemical properties to the original epitope are not the sole determining factors for the observed immunostimulatory activity of the mimic peptides .\n OUTPUT:\n" }, { "from": "agent", "value": "avoiding immune destruction" } ]

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

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

However , 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" } ]

The mechanism that controls total cell number is known as contact inhibition of growth and it depends on the NF2/Merlin pathway .

However , how necrotic cells influence the induction of antigen-specific CD8(+) T cell-mediated adaptive immune responses under sterile conditions , in the absence of pathogen associated molecular patterns ( PAMPs ) , remains poorly understood . Here , we examined antigen-specific CD8(+) T-cell responses to primary sterile necrotic tumor cells both in vitro and in vivo . We found that primary necrotic cells alone fail to generate CD8(+) T cell-dependent immune responses toward cell-associated antigens . We show that necrotic cells trigger CD8(+) T-cell immunity only in the presence of PAMPs or analogs , such as p(dI-dC) and/or unmethylated CpG DNA . The electroporation of tumor cells with these PAMPs prior to necrosis induction triggered antigen-specific CD8(+) T-cell responses through a TLR9/MyD88-dependent pathway . In addition , we found that necrotic cells contain factors that can block the cross-priming of CD8(+) T cells even under non-sterile conditions and can serve as a possible mechanism of immunosuppression . These results suggest that antigen-specific CD8(+) T-cell responses to primary necrotic tumor cells can be induced in the presence of PAMPs and thus have a substantial impact on the development of antitumor vaccination strategies .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death;tumor promoting inflammation;avoiding immune destruction" } ]

For this purpose , we compared pre-treatment urinary neopterin levels measured in 92 ovarian cancer patients , with intratumoral levels of mRNA transcripts from factors either involved in the adaptive antitumor immune defense ( CD3 , IFN-γ , IRF-1 , IRF-2 , SOCS1 and iNOS ) or immune tolerance ( FoxP3 ) . This study did not reveal an association between urinary neopterin and one of these investigated \" on tumor site transcripts \" . From all the factors reflecting the magnitude of the local adaptive antitumor response , intratumoral IRF-1 expression above the edge of the 25th percentile was found to predict most reliably favorable progression-free ( median 34 months vs. 10 months ; p &lt ; 0.001 ) and overall ( median 52 months vs. 16 months ; p &lt ; 0.001 ) survival . In contrast , pre-treatment urinary neopterin excretion above 275 μmol/mol creatinine , which indicates an unspecific activation of the innate immune system , was associated with a very poor overall survival with a median of only 11 months when compared with a median overall survival of 40 months in patients with lower urinary neopterin excretion ( p = 0.021 ) . Interestingly , the considerable survival benefit in patients with high IRF-1-expressing cancers was completely abrogated as well for progression-free as for overall survival when urinary neopterin concentrations were found to be concomitantly elevated . These findings demonstrate that in ovarian carcinomas the unspecific \" cancer-related inflammation \" contributes to a significant subversion of the adaptive antitumor immune defense mounted at the tumor site .\n OUTPUT:\n" }, { "from": "agent", "value": "tumor promoting inflammation" } ]

To resolve these contradictory observations , we studied radiosensitivities by employing breast cancer stem cell ( CSC)-like MDA-MB231 and MDA-MB453 cells as well as their corresponding non-stem cells . CSC-like cells proliferate without differentiating and have characteristics of tumor-initiating cells [ 1 ] . These cells were exposed to γ-rays ( 1.25-8.75 Gy ) and survival curves were determined by colony formation . A final slope , D(0) , of the survival curve for each cell line was determined to measure radiosensitivity . The D(0) of CSC-like and non-stem MDA-MB-453 cells were 1.16 Gy and 1.55 Gy , respectively . Similar results were observed in MDA-MB-231 cells ( 0.94 Gy vs. 1.56 Gy ) . After determination of radiosensitivity , we investigated intrinsic cellular determinants which influence radiosensitivity including cell cycle distribution , free-radical scavengers and DNA repair . We observed that even though cell cycle status and antioxidant content may contribute to differential radiosensitivity , differential DNA repair capacity may be a greater determinant of radiosensitivity . Unlike non-stem cells , CSC-like cells have little/no sublethal damage repair , a low intracellular level of ataxia telangiectasia mutated ( ATM ) and delay of γ-H2AX foci removal ( DNA strand break repair ) . These results suggest that low DNA repair capacity is responsible for the high radiosensitivity of these CSC-like cells .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation" } ]

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

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

This phenomenon , known as the Warburg effect , is an anomalous characteristic of glucose metabolism in cancer cells . Chronic inflammation is a key promoting factor of tumourigenesis . It remains , however , largely unexplored whether and how pro-tumourigenic inflammation regulates glucose metabolism in cancer cells . Here , we show that pro-inflammatory cytokines promote glycolysis in breast cancer cells , and that the inflammation-induced miR-155 functions as an important mediator in this process . We further show that miR-155 acts to upregulate hexokinase 2 ( hk2 ) , through two distinct mechanisms . First , miR-155 promotes hk2 transcription by activation of signal transducer and activator of transcription 3 ( STAT3 ) , a transcriptional activator for hk2 . Second , via targeting C/EBPβ ( a transcriptional activator for mir-143 ) , miR-155 represses mir-143 , a negative regulator of hk2 , thus resulting in upregulation of hk2 expression at the post-transcriptional level . The miR-155-mediated hk2 upregulation also appears to operate in other types of cancer cells examined . We suggest that the miR-155/miR-143/HK2 axis may represent a common mechanism linking inflammation to the altered metabolism in cancer cells .\n OUTPUT:\n" }, { "from": "agent", "value": "cellular energetics;tumor promoting inflammation" } ]

Oxidative stress affects many signaling pathways and may cause the induction of autophagy . The NF-E2-related factor 2 ( Nrf2)/Kelch-like ECH-associated protein 1 ( Keap1 ) signaling pathway is the main pathway responsible for cell defense against oxidative stress and Nrf2 is a critical transcription factor related with cancer multidrug resistance . However , the relation between Nrf2 and regulation of autophagy is not well understood . In this study , we used temozolomide ( TMZ ) , which inhibited the viability of GBM cells mainly by inducing autophagic cell death and explored the role of Nrf2 downregulation on autophagy induced by TMZ in GBM cells . In U251-Si-Nrf2 48h after transfection the protein levels of Nrf2 were significantly downregulated , while the protein levels of LC3B-II increased by western blot analysis . Knockdown of Nrf2 also led to a significant increase of autophagic vacuoles and acidic vesicular organelles ( AVOs ) , revealed by trans-mission electron microscopy ( TEM ) and acridine orange ( AO ) staining using flow cytometry . Collectively , these findings demonstrate that knockdown of Nrf2 can enhance the basal level of autophagy in the U251 glioma cell line . Furthermore , after the treatment with TMZ ( 100µM ) for 3 days , the U251-Si-Nrf2 transfected cells showed less viability rate by cell counting kit-8 ( CCK-8 ) assay and the levels of autophagy increased obviously through analysis of western blot and AO staining using flow cytometry . Taken together , our results suggest that knockdown of Nrf2 may enhance autophagy induced by TMZ in the U251 glioma cell line , which should be further evaluated for novel anticancer activity .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death" } ]

However , its roles in tumor survival have not yet been fully elucidated . Here , we found for the first time that JAK2/STAT3 was activated in HeLa cells when they were starved or treated with rapamycin . STAT3 activation was associated with autophagic processes , because it was completely inhibited by 3-methyladenine , partially inhibited by knockdown of molecules associated with autophagic processes and blocked by antioxidants , DPI , a Nox inhibitor and knockdown of p22 phox , indicating that ROS generated by Nox that was activated during autophagic processes activated JAK2/STAT3 pathway . Activated STAT3 directly bound to IL6 promoter and increased IL6 mRNA and protein secretion . Finally , the conditioned media , which included IL6 , from starved HeLa cells promoted cancer cell survival in both normal and starved conditions , confirmed by clonogenic , proliferation and cell death assays . These data together indicate that the autophagic process in cancer cells can contribute to their survival by JAk2/STAT3 activation and subsequent secretion of growth factors .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling" } ]

Recently , four novel family members , RASSF7-10 , have been identified by homology searches for RA-domain-containing proteins . These additional RASSF members are divergent and structurally distinct from RASSF1-6 , containing an N-terminal RA domain and lacking the Sav/RASSF/Hpo ( SARAH ) domain . Here , we show that RASSF8 is ubiquitously expressed throughout the murine embryo and in normal human adult tissues . Functionally , RNAi-mediated knockdown of RASSF8 in non-small-cell lung cancer ( NSCLC ) cell lines , increased anchorage-independent growth in soft agar and enhanced tumor growth in severe combined immunodeficiency ( SCID ) mice . Furthermore , EdU staining of RASSF8-depleted cells showed growth suppression in a manner dependent on contact inhibition . We show that endogenous RASSF8 is not only found in the nucleus , but is also membrane associated at sites of cell-cell adhesion , co-localizing with the adherens junction ( AJ ) component beta-catenin and binding to E-cadherin . Following RASSF8 depletion in two different lung cancer cell lines using alternative small interfering RNA ( siRNA ) sequences , we show that AJs are destabilized and E-cadherin is lost from the cell membrane . The AJ components beta-catenin and p65 are also lost from sites of cell-cell contact and are relocalized to the nucleus with a concomitant increase in beta-catenin-dependent and nuclear factor-kappaB ( NF-kappaB)-dependent signaling following RASSF8 depletion . RASSF8 may also be required to maintain actin -cytoskeletal organization since immunofluorescence analysis shows a striking disorganization of the actin- cytoskeleton following RASSF8 depletion . Accordingly , scratch wound healing studies show increased cellular migration in RASSF8-deficient cells . These results implicate RASSF8 as a tumor suppressor gene that is essential for maintaining AJs function in epithelial cells and have a role in epithelial cell migration .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors" } ]

PANC-1 cells , a kind of human pancreatic carcinoma cell line , were cultured in this study. p120ctn was immunocytochemically detected in PANC-1 cells . The recombinant lentivirus vector was constructed to knock down the p120ctn expression of PANC-1 cells . Real-time quantitative PCR ( RQ-PCR ) and Western blotting were used to determine the expression of p120ctn and E-cadherin in PANC-1 cells after p120ctn knockdown . The adhesion , invasion and migration capacity of PANC-1 cells after p120ctn knockdown was detected by cell adhesion , invasion and migration assays . Cell growth was measured by the MTT method . Cell cycle and apoptosis were analyzed by fluorescence-activated cell sorting . The results showed that p120ctn knockdown led to significantly down-regulated E-cadherin and a reduced cell-to-cell adhesion ability in PANC-1 cells. shRNA-mediated knockdown of p120ctn reduced invasion and migration capacity of PANC-1 cells , inhibited cell growth , caused a significant decrease in the percentage of cells in G(1) , an increase in S , and promoted apoptosis of PANC-1 cells . It was concluded that p120ctn plays a pivotal role in the proliferation and metastasis of pancreatic carcinoma , suggesting that p120ctn is a novel target for pancreatic carcinoma treatment .\n OUTPUT:\n" }, { "from": "agent", "value": "activating invasion and metastasis" } ]

In the absence of a proven effective therapy for HCC , novel chemopreventive strategies are urgently needed to lower the current morbidity and mortality of HCC . Recently , we have reported that resveratrol , a compound present in grapes and red wine , significantly prevents diethylnitrosamine ( DENA)-induced liver tumorigenesis in rats , although the mechanism of action is not completely understood . In the present study , we have examined the underlying mechanisms of resveratrol chemoprevention of hepatocarcinogenesis by investigating the effects of resveratrol on oxidative damage and inflammatory markers during DENA-initiated rat liver carcinogenesis . There was a significant increase in hepatic lipid peroxidation and protein oxidation in carcinogen control animals compared with their normal counterparts at the end of the study ( 20 weeks ) . Elevated expressions of inducible nitric oxide synthase and 3-nitrotyrosine were noticed in the livers of the same animals . Dietary resveratrol ( 50-300 mg/kg ) administered throughout the study reversed all the aforementioned markers in a dose-responsive fashion in rats challenged with DENA . Resveratrol also elevated the protein and mRNA expression of hepatic nuclear factor E2-related factor 2 ( Nrf2 ) . Results of the present investigation provide evidence that attenuation of oxidative stress and suppression of inflammatory response mediated by Nrf2 could be implicated , at least in part , in the chemopreventive effects of this dietary agent against chemically induced hepatic tumorigenesis in rats .

A mutant , SWAP-70-374 , was found to be able to bind to F-actin in vitro , whereas wild-type SWAP-70 failed to do so . This mutant was present at the plasma membrane without any stimulation while the wild-type protein was present only in the cytosol unless cells were stimulated with EGF . Expression of this mutant in MEFs resulted in morphologic transformation , fast growth , and loss of contact inhibition , suggesting that SWAP-70 with this mutation can transform the cells . ERK1/2 was activated in SWAP-70-374-transformed cells . Use of MEK inhibitors revealed that the ERK1/2 pathway does not affect the cell growth of MEFs but is responsible for loss of contact inhibition . To investigate the function of SWAP-70 further , drugs that can inhibit SWAP-70-dependent cell responses were screened . Among various drugs , sanguinarine was found to inhibit transformation of MEFs by SWAP-70-374 . This drug was able to inhibit SWAP-70-mediated membrane ruffling as well , suggesting that its effect was closely related to the SWAP-70 signaling pathway .

The goal of this study was to identify and characterize cell cycle-regulatory mechanisms responsible for the anti-mitogenic effect of apoE . METHODS AND RESULTS Primary VSMCs were stimulated with serum in the absence or presence of apoE3. apoE3 upregulated expression of the cdk inhibitor , p27(kip1) , in primary VSMCs , and this effect required Cox2 and activation of PGI(2)-IP signaling . The microRNA family , miR221/222 has recently been identified as a post-translational regulator of p27 , and apoE3 inhibited miR221/222 expression in a Cox2- and PGI(2)/IP-dependent manner . Moreover , reconstituted miR222 expression was sufficient to override the effects of apoE on p27 expression and S phase entry . The ability to repress expression of miR221/222 is shared by apoE3-containing HDL but is absent from apoA-1 , LDL and apoE-depleted HDL . All three apoE isoforms regulate miR221/222 , and the effect is independent of the C-terminal lipid-binding domain. miR221/222 levels are increased in the aortae of apoE3-null mice and reduced when apoE3 expression is reconstituted by adeno-associated virus infection . Thus , regulation of miR221/222 by apoE3 occurs invivo as well as invitro . CONCLUSIONS ApoE inhibits VSMC proliferation by regulating p27 through miR221/222 . Control of cell cycle-regulatory microRNAs adds a new dimension to the spectrum of cardiovascular protective effects afforded by apoE and apoE-HDL .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors" } ]

We now describe a highly significant correlation between STAT5 expression and the incidence of BCR-ABL1 mutations in primary CML . Forced expression of STAT5 in murine BCR-ABL1 transformed cells sufficed to enhance the production of reactive oxygen species ( ROS ) and to trigger DNA damage . STAT5-mediated ROS production is independent of JAK2 but requires concomitant BCR-ABL1 signalling as forced STAT5 expression in untransformed BCR-ABL1 negative cells has no impact on ROS levels . Only within the context of a BCR-ABL1 positive cell does STAT5 transcriptionally regulate a target gene or set of genes that causes the enhanced ROS production . Our study suggests the existence of a feed-forward loop accelerating disease progression , in which BCR-ABL1 enhances its own mutation rate in a STAT5-ROS dependent manner . This model explains the increased occurrence of inhibitor-resistant BCR-ABL1 mutations in advanced disease stages driven and characterized by high STAT5 expression .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation;tumor promoting inflammation" } ]

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

Panitumumab ( pmAb ) is a fully human IgG2 anti-EGFR antibody that blocks the EGFR actions . In the present study , we evaluated the effects of pmAb on the EGF-mediated cellular responses in a panel of colon cancer cells ( HCT-8 , HT-29 , DLD-1 and HCT-116 ) . HCT-1116 and DLD-1 cells showed no significant EGF-dependent cell proliferation ; HT-29 and HCT-8 exhibited an EGF-dependent proliferation , with HCT-8 cells to be the most responsive with significant EGFR phosphorylation upon treatment with EGF . The effects of pmAb were then evaluated in the most EGF-responsive cells , HCT-8 . In that respect , pmAb impedes the signaling cascade mediated by EGFR intracellular phosphorylation and activity of focal adhesion kinase ( FAK ) as well as the EGF-induced invasive and migratory potential of colon cancer cells . At the level of matrix effectors implicated in colon cancer progression we report that pmAb is a potent inhibitor of constitute and EGF-mediated gene expression of certain matrix effectors , such as membrane-type 1 metalloproteinase ( MT1-MMP ) , extracellular metalloproteinases inducer ( EMMPRIN ) , urokinase plasminogen activator ( uPA ) and syndecan-4 .

METHODS Eighty cases of invasive cervical squamous cancer were selected as objects of our study . Double immunohistochemical staining with antibodies against lymphatic vessel endothelial hyaluronan receptor 1 and Ki-67 was used to label the lymphatic vessels and mark the proliferative lymphatic vessels in cervical squamous cancer . The peritumoral lymphatic vessel density and intratumoral lymphatic vessel density was assessed . The lymphatic vessels proliferation index was evaluated by calculating Ki-67 proliferation index ( PI ) to reflect the lymphangiogenesis of cervical squamous cancer . Then the correlation between lymphangiogenesis and clinicopathologic features of cervical squamous cancer was analyzed . RESULTS The LVD of cervical cancer ( 15.23 � 3.6 ) was clearly higher than that of the adjacent normal cervical subepithelial tissues ( 9.9 � 2.5 , P &lt ; 0.001 ) . The peritumoral lymphatic vessel density of cervical cancer ( 18.75 � 4.3 ) was significantly higher than the intratumoral lymphatic vessel density of cervical cancer ( 11.71 � 4.9 , P &lt ; 0.001 ) . Lymphatic PI ( LPI ) of cervical cancer ( 0.258 � 0.07 ) was higher than that of the adjacent normal cervical subepithelial tissues ( 0.068 � 0.08 , P &lt ; 0.001 ) . The peritumoral lymphatic vessel PI of cervical cancer ( 0.324 � 0.06 ) was notably higher than the intratumoral lymphatic vessel PI of cervical cancer ( 0.232 � 0.06 , P &lt ; 0.001 ) . Peritumoral lymphatic vessel density and peritumoral lymphatic vessel were clearly associated with the lymph node metastasis ( P = 0.001 and P = 0.002 , respectively ) and lymphovascular space invasion ( P = 0.024 and P = 0.01 , respectively ) .

Obesity is an inflammatory state , and chronic colonic inflammation induces CRC . OBJECTIVE We conducted this proof-of-principle study to seek evidence of obesity-associated colorectal inflammation and to evaluate effects of diet-induced weight loss . DESIGN We measured inflammatory cytokines , gene arrays , and macrophage infiltration in rectosigmoid mucosal biopsies of 10 obese premenopausal women [ mean ± SD body mass index ( in kg/m(2) ) : 35 ± 3.5 ] before and after weight loss induced by a very-low-calorie diet . RESULTS Subjects lost a mean ( ±SD ) of 10.1 ± 1% of their initial weight . Weight loss significantly reduced fasting blood glucose , total cholesterol , triglycerides , LDL , tumor necrosis factor-α ( TNF-α ) , and interleukin ( IL)-8 concentrations ( P &lt ; 0.05 ) . After weight loss , rectosigmoid biopsies showed a 25-57% reduction in TNF-α , IL-1β , IL-8 , and monocyte chemotactic protein 1 concentrations ( P &lt ; 0.05 ) . T cell and macrophage counts decreased by 28% and 42% , respectively ( P &lt ; 0.05 ) . Gene arrays showed dramatic down-regulation of proinflammatory cytokine and chemokine pathways , prostaglandin metabolism , and the transcription factors STAT3 ( signal transducer and activator of transcription 3 ) and nuclear transcription factor κB . Weight loss reduced expression of FOS and JUN genes and down-regulated oxidative stress pathways and the transcription factors ATF ( activating transcription factor ) and CREB ( cyclic AMP response element-binding ) . CONCLUSIONS Our data show that diet-induced weight loss in obese individuals reduces colorectal inflammation and greatly modulates inflammatory and cancer-related gene pathways . These data imply that obesity is accompanied by inflammation in the colorectal mucosa and that diet-induced weight loss reduces this inflammatory state and may thereby lower CRC risk .\n OUTPUT:\n" }, { "from": "agent", "value": "tumor promoting inflammation" } ]

While many studies demonstrate that ER and NF-κB can repress each other , we previously identified a gene signature that is synergistically upregulated by these two factors in more aggressive luminal B breast tumors . Herein , we examine a novel mechanism of cross talk between ER and NF-κB that results in the upregulation of the antiapoptotic gene BIRC3 ( also known as cIAP2 ) . We demonstrate that NF-κB , acting through two response elements , is required for ER recruitment to an adjacent estrogen response element ( ERE ) in the BIRC3 promoter . This effect is accompanied by a major increase in NF-κB-dependent histone acetylation around the ERE . Interestingly , CBP , a histone acetyltransferase previously implicated in repressive interactions between ER and NF-κB , plays a permissive role by promoting histone acetylation and ER recruitment , as well as enhanced expression of BIRC3 . These findings suggest a new gene regulatory mechanism by which inflammation and NF-κB activation can influence ER recruitment to inherently inactive ER binding sites . This fine-tuning mechanism may explain how two factors that generally repress each other's activity may work together on certain genes to promote breast cancer cell survival and tumor progression .\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling;tumor promoting inflammation" } ]

As a first step in this direction the octamer 5'-d(CCGGCGGT) , containing the sequence of the codons 12 d(GGC) and 13 d(GGT) of the human H-ras gene , was reacted with the antitumoral drug cis-diamminedichloroplatinum(II) .

A first set of experiments , including enzymatic digestions with nuclease P1 followed by alkaline phosphatase and acid-catalysed hydrolysis , allowed us to determine which bases were engaged in the cis-DDP lesions . Our results indicate that only guanine residues were chelated with cisplatin to yield bifunctional adducts . Furthermore , by performing enzymatic digestions with phosphodiesterases , we have located the adducts with respect to the 5 ' end of the octamer .

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 .

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

The angiogenic cascade during tumor development consists of the release of angiogenic factors and binding of angiogenic factors to receptors on endothelial cells to activate downstream signaling pathways . However , the potential medicinal value of glyceollins , especially in antiangiogenesis , remains unexplored . METHODS AND RESULTS Here , we investigated the antiangiogenic activity of glyceollins and their underlying mechanisms . Glyceollins inhibited vascular endothelial growth factor ( VEGF ) or basic fibroblast growth factor ( bFGF ) induced in vitro angiogenic activity . Glyceollins inhibited VEGF receptor-2 or FGF receptor-1 activity and their downstream signaling pathways such as extracellular regulated kinase 1/2 , c-Jun N-terminal kinase , as well as p38 mitogen-activated protein kinase and focal adhesion kinase induced by VEGF or bFGF . Glyceollins significantly suppressed VEGF receptor-2 kinase activity assayed by the ELISA . Glyceollins significantly attenuated in vivo and ex vivo microvessel development in a dose-dependent manner and tumor growth by suppressing microvessel density in Lewis lung carcinoma ( LLC ) mouse xenograft .

However , the significance of ANXA2 expression in gastric carcinoma has not been clarified.To elucidate its roles in growth of gastric cancer , ANXA2 expression in SGC-7901 cells was inhibited with a designated siRNA , then cell proliferation , cell cycling , apoptosis and motility were determined by MTT assay , flow cytometry , Hoechst 33342 staining and wound healing assay , respectively . To further assess the behavior of ANXA2 deleted SGC- 7901 cells , changes of microstructures were observed under fluorescence microscopy , laser scanning confocal microscopy and electron microscopy . We found that inhibition of ANXA2 expression caused cell proliferation to decrease significantly with G1 arrest , motility to be reduced with changes in pseudopodia/filopodia structure and F-actin and β-tubulin expression , and apoptosis to be enhanced albeit without significance . At the same time , ANXA2 deletion resulted in fewer pseudopodia/filopodia , non-stained areas were increased , contact inhibition among cells reappeared , and expression of F-actin and β-tubulin was decreased , with induction of polymerized disassembled forms . Taken together , these data suggest that ANXA2 overexpression is important to maintain the malignancy of cancer cells , and this member of the annexin family has potential to be considered as a target for the gene therapy of gastric carcinoma .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors;resisting cell death;sustaining proliferative signaling" } ]

Thus , it is important to evaluate the toxic effects of this compound . In the present study , we evaluated the cytotoxic , genotoxic and mutagenic properties of DPDT in Chinese hamster fibroblast ( V79 ) cells , in strains of the yeast Saccharomyces cerevisiae both proficient and deficient in several DNA repair pathways and in Salmonella typhimurium . DPDT induced frameshift mutations in both S.typhimurium and a haploid wild-type strain of S.cerevisiae . Mutants of S.cerevisiae defective in base excision repair and recombinational repair were more sensitive to DPDT . The results of a lactate dehydrogenase leakage assay suggest that DPDT is cytotoxic to V79 cells . At cytotoxic concentrations , this compound increased thiobarbituric reactive species levels and decreased the glutathione:GSSH ratio in yeast and V79 cells . DPDT generated single- and double-strand DNA breaks in V79 cells , both with and without metabolic activation , as revealed by alkaline and neutral comet assays . Moreover , an induction of oxidative DNA base damage was indicated by a modified comet assay using formamidopyrimidine DNA glycosylase and endonuclease III . Treatment with DPDT also induced micronucleus formation in V79 cells . Pre-incubation with N-acetylcysteine reduced DPDT's oxidative , genotoxic and mutagenic effects in yeast and V79 cells . Our results suggest that the toxic and mutagenic properties of DPDT may stem from its ability to disturb the redox balance of the cell , which leads to oxidative stress and the induction of DNA damage .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation" } ]

Cytotoxicity is mediated by transition metal-dependent generation of H(2)O(2) in the interstitial space . In this study , the sensitivity of neuroblastoma cells ( Kelly , SK-N-SH ) to ascorbate and H(2)O(2) and their defense mechanisms against H(2)O(2) were investigated . Since aerobic glycolysis ( the Warburg effect ) is a feature of many tumour cells , their glucose consumption and lactate production were monitored . Furthermore , synthesis and release of ferritin by neuroblastoma cells were analysed in order to examine whether ferritin is possibly an iron source for H(2)O(2) generation . Ascorbate ( 0.6-5.0 mM ) and H(2)O(2) ( 25-100 muM ) were found to be similarly cytotoxic to Kelly and SK-N-SH cells . In each case , cytotoxicity increased if cell concentrations decreased , in accordance with low cell concentrations having lower capacities to detoxify H(2)O(2) . Kelly and SK-N-SH cells produced and released remarkable amounts of lactate and ferritin . We propose the selective cytotoxicity of high dose ascorbate to tumour cells to be due to the preferential generation of H(2)O(2) in the acidic and ferritin-rich tumour microenvironment , combined with reduced defense systems against H(2)O(2) as a consequence of aerobic glycolysis .\n OUTPUT:\n" }, { "from": "agent", "value": "cellular energetics" } ]

METHODS pol beta wild-type cells ( pol beta +/+ ) , pol beta null cells ( pol beta -/- ) and wild-type pol beta overexpressed cells ( pol beta oe ) which had the same genetic background were studied . Firstly , RT-PCR and Western blot targeting to pol beta were carried out to measure the expression of pol beta mRNA and protein in above three kinds of cells , then MTT test and single cell gel electrophoresis ( comet assay ) were used to compare cell viability and DNA damage/repair of the three kinds of cells when exposed to BaP . RESULTS There was pol beta deletion in pol beta -/- cells and the level of pol beta mRNA and protein in pol beta oe cells was twice higher than that in pol beta +/+ cells . BaP could induce DNA damage and reduce cell viability , when compared with pol beta +/+ cells , IC50 of pol beta -/- cells was remarkably lower , DNA was prone to damage and more difficult to be repaired , on the other hand , IC50 of pol beta oe cells was obviously higher and the damage effect on DNA was weaker and prone to be repaired . CONCLUSION Pol beta played an important role in the repair of DNA damage induced by BaP , deficiency of pol beta could decrease the DNA repair capability of cells , and overexpression of pol beta could help cells response to DNA damage and protect cells from death in a certain degree .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation" } ]

Radiation-induced normal tissue injury , including progressive cognitive impairment , however , can significantly affect the well-being of the approximately 200,000 patients who receive these treatments each year in the United States . Although the exact mechanisms underlying radiation-induced late effects remain unclear , oxidative stress and inflammation are thought to play a critical role . Microglia are key mediators of neuroinflammation . Peroxisomal proliferator-activated receptor ( PPAR ) δ has been shown to be a potent regulator of anti-inflammatory responses . Thus , we hypothesized that PPARδ activation would modulate the radiation-induced inflammatory response in microglia . Incubating BV-2 murine microglial cells with the PPARδ agonist L-165041 prevented the radiation-induced increase in : ( i ) intracellular reactive oxygen species generation , ( ii ) Cox-2 and MCP-1 expression , and ( iii ) IL-1β and TNF-α message levels . This occurred , in part , through PPARδ-mediated modulation of stress-activated kinases and proinflammatory transcription factors . PPARδ inhibited NF-κB via transrepression by physically interacting with the p65 subunit and prevented activation of the PKCα/MEK1/2/ERK1/2/AP-1 pathway by inhibiting the radiation-induced increase in intracellular reactive oxygen species generation . These data support the hypothesis that PPARδ activation can modulate radiation-induced oxidative stress and inflammatory responses in microglia .\n OUTPUT:\n" }, { "from": "agent", "value": "tumor promoting inflammation" } ]

We studied the effect of the c-erbA/TR alpha proto-oncogene encoding a functional T(3) receptor ( TR alpha 1 ) , of its ligand T(3) , and of its retroviral , mutated counterpart , the v-erbA oncogene , on the proliferation capacity of nontumorigenic mammary epithelial cells ( EpH4 ) . We found that EpH4 cells expressing ectopically TR ( EpH4 + TR alpha 1 ) or v-erbA ( EpH4 + v-erbA ) proliferated faster than parental EpH4 cells that contained low levels of endogenous TR . T(3) inhibited DNA synthesis and proliferation in EpH4 + TR alpha 1 cells but not EpH4 or EpH4 + v-erbA cells . The study of cell-cycle genes showed that T(3) decreased cyclin D1 RNA and protein levels in EpH4 + TR alpha 1 cells . In addition , T(3) downregulated the expression of T1 , a gene that is overexpressed in human breast adenocarcinomas and is induced by mitogens , serum , and several oncogenes and cytokines . Inhibition of the T1 gene by T(3) required both de novo mRNA and protein synthesis . Furthermore , T(3) abolished the induction of T1 by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate and inhibited the activity of an activation protein 1-dependent promoter ( -73-Col-CAT ) in EpH4 + TR alpha 1 cells , suggesting that interference with activation protein 1 transcription factor plays a part in the inhibition of the T1 gene . Our results showed that T(3) reduced the proliferation of mammary epithelial cells and inhibited the expression of cyclin D1 and T1 genes .\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

New concepts in cancer treatment aim at inhibition of aerobic glycolysis . Pyruvate dehydrogenase converts pyruvate to acetylCoA thus preventing lactate formation . Therefore , the aim of this study was to evaluate compounds that could activate pyruvate dehydrogenase in cancer cells . We investigated the effects of ( R)-(+)-α-lipoic acid ( LPA ) and dichloroacetate ( DCA ) , possible activators of pyruvate dehydrogenase , on suppression of aerobic glycolysis and induction of cell death . The neuroblastoma cell lines Kelly , SK-N-SH , Neuro-2a and the breast cancer cell line SkBr3 were incubated with different concentrations ( 0.1-30 mM ) of LPA and DCA . The effects of both compounds on cell viability/proliferation ( WST-1 assay ) , [ 18F]-FDG uptake , lactate production and induction of apoptosis ( flow cytometric detection of caspase-3 ) were evaluated . Furthermore , NMRI nu/nu mice that had been inoculated s.c. with SkBr3 cells were treated daily for four weeks with LPA ( i.p , 18.5 mg/kg ) starting at day 7 p.i. . Tumor development was measured with a sliding calliper and monitored via [ 18F]-FDG-PET . Residual tumors after therapy were examined histopathologically . These data suggests that LPA can reduce ( 1 ) cell viability/proliferation , ( 2 ) uptake of [ 18F]-FDG and ( 3 ) lactate production and increase apoptosis in all investigated cell lines . In contrast , DCA was almost ineffective . In the mouse xenograft model with s.c . SkBr3 cells , daily treatment with LPA retarded tumor progression . Therefore , LPA seems to be a promising compound for cancer treatment .\n OUTPUT:\n" }, { "from": "agent", "value": "cellular energetics;resisting cell death" } ]

Starting at 6 weeks of age , a total of 37 male ACI/N rats were divided into two groups and treated as follows : group I ( 18 rats ) received diet containing 1% 1-HA for 12 months ; group II ( 19 rats ) was given the basal diet alone . Sub-groups of 5-7 rats were sequentially killed at 4 , 8 and 12 months for evaluation of the length , cell numbers and 5-bromo-2'-deoxyuridine ( BrDU ) labeling indices of large bowel crypts together with ODC activity . All kinetic and ODC data indicated increased DNA synthesis and proliferation at all time points . Morphological observation of the intestines also revealed melanosis , crypt abscesses and erosion , becoming more pronounced with length of exposure to the anthraquinone .

Vanadium pentoxide was nominated for study by the National Cancer Institute as a representative of the metals class study . Male and female F344/N rats and B6C3F1 mice were exposed to vanadium pentoxide ( 99% pure ) by inhalation for 16 days , 14 weeks , or 2 years . Genetic toxicology studies were conducted in Salmonella typhimurium and mouse peripheral blood. 16-DAY STUDY IN RATS : Groups of five male and five female rats were exposed to particulate aerosols of vanadium pentoxide at concentrations of 0 , 2 , 4 , 8 , 16 , or 32 mg/m(3) by inhalation , 6 hours per day , 5 days per week for 16 days . Three males in the 32 mg/m(3) group died before the end of the study . Mean body weights of males and females exposed to 8 mg/m(3) or greater were less than those of the chamber controls . Clinical findings included rapid respiration and hypoactivity in rats exposed to 16 or 32 mg/m(3) . Relative lung weights of 4 mg/m(3) or greater males and 2 mg/m(3) or greater females were significantly greater than those of the chamber controls . Lavage fluid analysis indicated an inflammatory response in the lung that was either directly mediated by vanadium pentoxide or was secondary to lung damage induced by vanadium pentoxide exposure. 16-DAY STUDY IN MICE : Groups of five male and five female mice were exposed to particulate aerosols of vanadium pentoxide at concentrations of 0 , 2 , 4 , 8 , 16 , or 32 mg/m(3) by inhalation , 6 hours per day , 5 days per week for 16 days . All males exposed to 32 mg/m(3) and one 8 mg/m(3) male died or were killed moribund before the end of the study . Mean body weights of 16 mg/m(3) males and 8 mg/m(3) or greater females were significantly less than those of the chamber controls , and the 32 mg/m(3) females lost weight during the study . Absolute and relative lung weights of 4 mg/m(3) or greater males and all exposed groups of females and liver weights of 16 mg/m(3) males were significantly greater than those of the chamber controls . The mediastinal lymph nodes were enlarged in 4 , 8 , and 16 mg/m(3) males and females , and lymphoid hyperplasia was confirmed histologically . Lavage fluid analysis indicated an inflammatory response in the lung that was either directly mediated by vanadium pentoxide or was secondary to lung damage induced by vanadium pentoxide exposure. 3-MONTH STUDY IN RATS : Groups of 10 male and 10 female rats were exposed to particulate aerosols of vanadium pentoxide at concentrations of 0 , 1 , 2 , 4 , 8 , or 16 mg/m(3) by inhalation , 6 hours per day , 5 days per week for 3 months . Seven males and three females exposed to 16 mg/m(3) died during the study . Mean body weights were significantly less in males exposed to 4 mg/m(3) or greater and in females exposed to 16 mg/m(3) . Abnormal breathing , thinness , lethargy , abnormal posture , and ruffled fur were observed in rats exposed to 16 mg/m(3) . Hematology results indicated that exposure of rats to vanadium pentoxide induced a microcytic erythrocytosis in males and females . Absolute and relative lung weights were significantly greater for 4 mg/m(3) or greater males and females than for the chamber controls as were the relative lung weights of 2 mg/m(3) males .

Alterations in pHi may contribute to abnormal proliferative responses such as those seen in tumorigenic cells . We observed that alkaline stress leads to genomic transformation of Madin-Darby canine kidney ( MDCK ) cells . Transformed cells ( F cells ) form \" foci \" in culture , lack contact inhibition , and are able to migrate , typical characteristics of dedifferentiated tumorigenic cells . F cells exhibit spontaneous biorhythmicity . Rhythmic transmembrane Ca2+ flux activates plasma membrane K+ channels and Na+/H+ exchange . This leads to periodic changes of membrane voltage and pHi at about one cycle per minute .

Quercetin reversibly blocked the cell cycle at a point 3-6 h before the start of DNA synthesis . Expression of the growth-related genes histone H4 , cyclin A and B , and p34cdc2 was suppressed in cells blocked with quercetin . Comparison of the quercetin arrest points with those of the cell cycle inhibitors aphidicolin and mimosine revealed a temporal order of arrest points in G1 of quercetin , mimosine , and aphidicolin . Mimosine and aphidicolin did not inhibit the expression of cyclin A or p34cdc2 , whereas all three reagents inhibited expression of cyclin B. Low concentrations of the protein inhibitor cycloheximide inhibited release of the quercetin but not the mimosine or aphidicolin block . A [ 35S]methionine-labeled M(r) 60,000 protein disappeared in quercetin-treated cells and was rapidly synthesized after removal of quercetin , suggesting the possibility that the M(r) 60,000 protein induces DNA synthesis after the cell is released from a quercetin block . These results suggest the usefulness of quercetin in studies of the regulation of late G1 phase .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

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" } ]

When C6-ceramide is encapsulated in a nanoliposome bilayer formulation , cell death is selectively induced in tumor models . However , the mechanism underlying this selectivity is unknown . As most tumors exhibit a preferential switch to glycolysis , as described in the \" Warburg effect \" , we hypothesize that ceramide nanoliposomes selectively target this glycolytic pathway in cancer . We utilize chronic lymphocytic leukemia ( CLL ) as a cancer model , which has an increased dependency on glycolysis . In CLL cells , we demonstrate that C6-ceramide nanoliposomes , but not control nanoliposomes , induce caspase 3/7-independent necrotic cell death . Nanoliposomal ceramide inhibits both the RNA and protein expression of GAPDH , an enzyme in the glycolytic pathway , which is overexpressed in CLL . To confirm that ceramide targets GAPDH , we demonstrate that downregulation of GAPDH potentiates the decrease in ATP after ceramide treatment and exogenous pyruvate treatment as well as GAPDH overexpression partially rescues ceramide-induced necrosis . Finally , an in vivo murine model of CLL shows that nanoliposomal C6-ceramide treatment elicits tumor regression , concomitant with GAPDH downregulation . We conclude that selective inhibition of the glycolytic pathway in CLL cells with nanoliposomal C6-ceramide could potentially be an effective therapy for leukemia by targeting the Warburg effect .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death;cellular energetics" } ]

Mutations in the VHL gene cause VHL syndrome , which is characterized by highly vascularized tumors . Here we report a c.464T>A mutation of the VHL gene in three patients with hemangioblastoma from a Chinese family . This mutation was not reported previously and was absent in the unaffected family members . The mutation is predicted to cause Val to Glu substitution at VHL protein residue 155 in a conserved region . Previous biochemical studies demonstrated that residue Val-155 was critical for VHL protein binding to chaperonin TRiC/CCT , an essential step for proper VHL protein folding . Our finding of naturally occurring VHL V155E mutation in patients with VHL syndrome supports the functional importance of Val-155 residue in VHL protein and illustrates the diversity of VHL gene defects underlying VHL syndrome .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation" } ]

Hypoxia-inducible factor ( HIF ) and oncoprotein Myc are two prominent transcription factors that drive glycolysis . Previously , we reported that the estrogen-related receptors ( ERRs ) act as cofactors of HIF and enhance HIF-dependent transcription of glycolytic genes under hypoxia . ERRs are orphan nuclear receptors and key regulators of energy metabolism by orchestrating mitochondrial biogenesis , fatty acid oxidation ( FAO ) and oxidative phosphorylation . Here , we show that ERRs also stimulate glycolysis under normoxia . ERRs directly bind to and activate promoters of many genes encoding glycolytic enzymes , and the ERR-binding sites in such promoters are essential for ERR-mediated transcriptional activation . ERRs interact with Myc , and the two factors synergistically activate transcription of glycolytic genes . Furthermore , overexpression of ERRs increases glycolytic gene expression and lactate production . Conversely , depletion of ERRs in cancer cells reduces expression of glycolytic genes and glucose uptake , resulting in decreased aerobic glycolysis and cell growth . Taken together , these results suggest that ERRs are important transcriptional activators of the glycolytic pathway and contribute to the Warburg effect in cancer cells .\n OUTPUT:\n" }, { "from": "agent", "value": "cellular energetics;sustaining proliferative signaling" } ]

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

In this study , we found a significant antiproliferative effect of Sup ODNs on the A549 non‑small cell lung cancer ( NSCLC ) cell line compared to those treated with control ODNs ( p<0.05 ) . Sup-ODN-mediated G1 phase cell cycle arrest was achieved via inhibition of Akt and extracellular signal-regulated kinase 1/2 phosphorylation and the p15INK4b and p27KIP1/retinoblastoma protein pathway . In addition , Sup ODNs induced apoptosis and enhanced apoptosis when combined with vinorelbine . In a setting similar to clinical use of multidrug chemotherapy for advanced NSCLC , these effects were investigated by using Sup ODNs in combination with conventional anticancer drugs . Sup ODNs had a significant synergistic effect with 5-fluorouracil , vinorelbine , gemcitabine , paclitaxel and irinotecan , with a mean combination index of 0.43-0.78 ( <1.0 indicates synergism ) in the A549 NSCLC cell line . In conclusion , our results showed that Sup ODNs have an anticancer effect and increase the sensitivity of NSCLC cells to conventional anticancer drugs by modifying Akt and the extracellular signal-regulated kinase 1/2 pathway .

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

Here , we investigated the anti-tumor activity of periplocin against lung cancer cells bothin vitro and in vivo , and explored its anti-cancer mechanism . Periplocin inhibited the growth of lung cancer cells and induced their apoptosis in time- and dose-dependent manners by cell cycle arrest in G0/G1 phase . Periplocin exhibited anti-tumor activity both in human ( A549 ) and mouse ( LL/2 ) lung cancer xenograft models . Immunohistochemical analysis revealed that intratumoral angiogenesis was significantly suppressed . Furthermore , anti-cancer activity mediated by periplocin was associated with decreased level of phosphorylated AKT and ERK both in vitro and in vivo , which were important for cell growth and survival . Moreover , periplocin induced apoptosis by downregulating Bcl-2 and upregulating Bax , leading to activation of caspase-3 and caspase-9 . These findings suggested that periplocin could inhibit the growth of lung cancer both in vitro and in vivo , which could be attributed to the inhibition of proliferation and the induction of apoptosis signaling pathway , such as AKT and ERK . These observations provide further evidence on the anti-tumor effect of periplocin , and it may be of importance to further explore its potential role as a therapeutic agent for cancer .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors;resisting cell death;inducing angiogenesis;sustaining proliferative signaling" } ]

Initial chemotherapeutic treatment could be successful ; however , resistance development urges the use of higher toxic doses accompanied by hematopoietic stem cell transplantation . The establishment of more effective treatments that can overcome or circumvent chemoresistance has become a priority . We recently demonstrated that venom extracted from Walterinnesia aegyptia ( WEV ) either alone or in combination with silica nanoparticles ( WEV+NPs ) mediated the growth arrest and apoptosis of prostate cancer cells . In the present study , we evaluated the impact of WEV alone and WEV+NP on proliferation and apoptosis of MM cells . Methods . The impacts of WEV alone and WEV+NP were monitored in MM cells from 70 diagnosed patients . The influences of WEV and WEV+NP were assessed with flow cytometry analysis . Results . WEV alone and WEV+NP decreased the viability of MM cells . Using a CFSE proliferation assay , we found that WEV+NP strongly inhibited MM cell proliferation . Furthermore , analysis of the cell cycle using the propidium iodide ( PI ) staining method indicated that WEV+NP strongly altered the cell cycle of MM cells and enhanced the induction of apoptosis .

The inactivation of multiple pathways that positively regulate senescence are required for immortalization . To identify these pathways in an unbiased manner , we performed DNA microarray analyses to assess the expression of 20,000 genes in human prostate epithelial cells ( HPECs ) passaged to senescence . These gene expression patterns were then compared with those of HPECs immortalized with the human Papillomavirus 16 E7 oncoprotein . Senescent cells display gene expression patterns that reflect their nonproliferative , differentiated phenotype and express secretory proteases and extracellular matrix components . A comparison of genes transcriptionally up-regulated in senescence to those in which expression is significantly down-regulated in immortalized HPECs identified three genes : the chemokine BRAK , DOC1 , and a member of the insulin-like growth factor axis , IGFBP-3 . Expression of these genes is found to be uniformly lost in human prostate cancer cell lines and xenografts , and previously , their inactivation was documented in tumor samples . Thus , these genes may function in novel pathways that regulate senescence and are inactivated during immortalization . These changes may be critical not only in allowing cells to bypass senescence in vitro but in the progression of prostate cancer in vivo .\n OUTPUT:\n" }, { "from": "agent", "value": "enabling replicative immortality" } ]

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

However , the immunosuppressive tumor microenvironment may limit the effectiveness of current immunotherapies . Antiangiogenic agents have the potential to modulate the tumor microenvironment and improve immunotherapy , but they often are used at high doses in the clinic to prune tumor vessels and paradoxically may compromise various therapies . Here , we demonstrate that targeting tumor vasculature with lower vascular-normalizing doses , but not high antivascular/antiangiogenic doses , of an anti-VEGF receptor 2 ( VEGFR2 ) antibody results in a more homogeneous distribution of functional tumor vessels . Furthermore , lower doses are superior to the high doses in polarizing tumor-associated macrophages from an immune inhibitory M2-like phenotype toward an immune stimulatory M1-like phenotype and in facilitating CD4(+) and CD8(+) T-cell tumor infiltration . Based on this mechanism , scheduling lower-dose anti-VEGFR2 therapy with T-cell activation induced by a whole cancer cell vaccine therapy enhanced anticancer efficacy in a CD8(+) T-cell-dependent manner in both immune-tolerant and immunogenic murine breast cancer models . These findings indicate that vascular-normalizing lower doses of anti-VEGFR2 antibody can reprogram the tumor microenvironment away from immunosuppression toward potentiation of cancer vaccine therapies . Given that the combinations of high doses of bevacizumab with chemotherapy have not improved overall survival of breast cancer patients , our study suggests a strategy to use antiangiogenic agents in breast cancer more effectively with active immunotherapy and potentially other anticancer therapies .\n OUTPUT:\n" }, { "from": "agent", "value": "inducing angiogenesis;avoiding immune destruction" } ]

One innovative approach is the use of targeted alpha therapy ( TAT ) to inhibit cancer growth , using an alpha particle emitting radioisotope such as ( 213)Bi . Because of its short range and high linear energy transfer ( LET ) , alpha-particles may be particularly effective in the treatment of cancer , especially in inhibiting the development of metastatic tumors from micro-metastases . Prostate-specific membrane antigen ( PSMA ) is expressed in prostate cancer cells and the neovasculature of a wide variety of malignant neoplasms including lung , colon , breast and others , but not in normal vascular endothelium . The expression is further increased in higher-grade cancers , metastatic disease and hormone-refractory prostate cancer ( PCA ) . J591 is one of several monoclonal antibodies ( mabs ) to the extracellular domain of PSMA . Chelation of J591 mab with ( 213)Bi forms the alpha-radioimmunoconjugate ( AIC ) . The objective of this preclinical study was to design an injectable AIC to treat human prostate tumors growing subcutaneously in mice . The anti-proliferative effects of AIC against prostate cancer were tested in vitro using the MTS assay and in vivo with the nude mice model . Apoptosis was documented using terminal deoxynucleotidyl transferase [ TdT]-mediated deoxyuridinetriphosphate [ dUTP ] nick end-labeling ( TUNEL ) assay , while proliferative index was assessed using the Ki-67 marker . We show that a very high density of PSMA is expressed in an androgen-dependent human PCA cell line ( LNCaP-LN3 ) and in tumor xenografts from nude mice . We also demonstrate that the AIC extensively inhibits the growth of LN3 cells in vitro in a concentration-dependent fashion , causing the cells to undergo apoptosis . Our in vivo studies showed that a local AIC injection of 50 microCi at 2 days post-cell inoculation gave complete inhibition of tumor growth , whereas results for a non-specific AIC were similar to those for untreated mice . Further , after 1 and 3 weeks post-tumor appearance , a single ( 100 microCi/100 microl ) intra-lesional injection of AIC can inhibit the growth of LN3 tumor xenografts ( volume<100 mm(3) ) in nude mice . Tumors treated with AIC decreased in volume from a mean 46+/-14 mm(3) in the first week or 71+/-15 mm(3) in the third week to non-palpable , while in control mice treated with a non-specific AIC using the same dose , tumor volume increased from 42 to 590 mm(3) . There were no observed side effects of the treatment . Because of its in vitro cytotoxicity and these anti-proliferative properties in vivo , the ( 213)Bi-J591 conjugate has considerable potential as a new therapeutic agent for the treatment of prostate cancer .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death" } ]

This requires both the identification of angiogenic regulators and their efficient delivery to target organs . Here , we demonstrate the use of a noncatalytic fragment of matrix metalloproteinase 2 ( termed PEX ) delivered by lentiviral vectors in different angiogenesis models . Transduction of human endothelial cells with PEX virus suppressed endothelial invasion and formation of capillary-like structures without affecting chemotaxis in vitro . Lentiviral delivery of PEX blocked basic fibroblast growth factor-induced matrix metalloproteinase 2 activation and angiogenesis on chicken chorioallantoic membranes . PEX expression also inhibited tumor-induced angiogenesis and tumor growth in a nude mouse model . Thus , our study shows that lentiviral vectors can deliver sufficient quantities of antiangiogenic substances to achieve therapeutic effects in vivo .\n OUTPUT:\n" }, { "from": "agent", "value": "inducing angiogenesis" } ]

MiRNAs also have been detected in the blood of cancer patients and can serve as circulating biomarkers . It has been shown that secreted miRNAs within exosomes can be transferred from cell to cell and can regulate gene expression in the receiving cells by canonical binding to their target messenger RNAs . Here we show that tumor-secreted miR-21 and miR-29a also can function by another mechanism , by binding as ligands to receptors of the Toll-like receptor ( TLR ) family , murine TLR7 and human TLR8 , in immune cells , triggering a TLR-mediated prometastatic inflammatory response that ultimately may lead to tumor growth and metastasis . Thus , by acting as paracrine agonists of TLRs , secreted miRNAs are key regulators of the tumor microenvironment . This mechanism of action of miRNAs is implicated in tumor-immune system communication and is important in tumor growth and spread , thus representing a possible target for cancer treatment .\n OUTPUT:\n" }, { "from": "agent", "value": "activating invasion and metastasis;tumor promoting inflammation" } ]

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" } ]

The attitude of sub-G1 peak in DNA histogram was determined by FCM . The TUNEL positive cell percentage was identified by terminal deoxynucleotidyl transferase ( TdT)-mediated Biotin dUNP end labeling technique . It was found that when HL-60 cells were treated with 25 mumol/L curcumin for 24 h , the expression level of Mcl-1 was down-regulated , but that of Bax and Bak up-regulated time-dependently . There was significant difference in the expression level of Mcl-1 , Bax and Bak between the curcumin-treated groups and control group ( P &lt ; 0.05-0.01 ) . At the same time , curcumin had no effect on progress of cell cycle in primaty acute myelogenous leukemia at newly diagnosis , but could increase the peak of Sub-G1 ( P &lt ; 0.05 ) , and down-regulate the expression of Mcl-1 and up-regulate the expression of Bax and Bak with the difference being statistically significant . The expression of P27kipl , P21wafl and pRbp- were elevated and that of cyclin D3 decreased in the presence of curcumin . These findings suggested that the Bcl-2 gene family indeed participated in the regulatory process of apoptosis induced by curcumin in HL-60 cells and AML cells . Curcumin can induce apoptosis of primary acute myelogenous leukemic cells and disturb cell cycle progression of HL-60 cells . The mechanism appeared to be mediated by perturbing G0/G1 phases checkpoints which associated with up-regulation of P27kipl , P21wafl and pRbp- expression , and down-regulation of cyclin D3 .\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors;resisting cell death" } ]

METHODS The clinical and histologic features of 5 cases of sinonasal IMT were reviewed . Immunohistochemical study for vimentin , MSA , SMA , calponin , h-caldesmon , desmin , ALK , fibronectin , CK , S-100 and Ki-67 was carried out . Ultrastructural examination was also performed in two of the cases . RESULTS The patients age ranged from 28 to 62 years ( mean = 43 years ) . The male-to-female ratio was 2:3 . The clinical presentation included nasal obstruction , nasal discharge , nasal bleeding , facial pain , facial swelling , toothache and tear overflow . All of the 5 patients suffered from disease relapses ; and 4 of them had recurrences for more than 5 times . One patient had lymph node metastasis and 3 patients died of the disease . Histologically , the tumor cells were arranged in interlacing fascicles and sometimes haphazard in fashion . They were spindly in shape , cytoplasm eosinophilic with mild nuclear atypia and a low mitotic activity . The intervening stroma was myxoid in appearance accompanied by lymphocyte and plasma cell infiltration , abundant blood vessels and focal collagenized areas . In 3 of the recurrent cases , the tumor cells displayed increased nuclear atypia and mitotic activity ( average about 5 to 6 per 10 high-power fields ) , accompanied by patchy necrosis , less inflammatory cell infiltration and focal sarcomatous changes . Immunohistochemical study showed that the tumor cells were diffusely positive for vimentin . SMA , MSA , calponin and fibronectin were variably expressed . Desmin was weakly positive in 1 case . The staining for h-caldesmon , ALK , S-100 and CK was negative . The Ki-67 proliferation index increased with tumor recurrences . Electron microscopy revealed abundant rough endoplasmic reticulum and dense body formation in the cytoplasm . There were an increased amount of collagen fibers in the stroma . CONCLUSIONS IMT rarely occurs in nasal cavity and paranasal sinuses . The tumor is prone to local invasion and recurrences , with subsequent progression to frank malignancy and distant metastasis , resulting in high mortality and poor prognosis . Complete surgical resection remains the main modality of treatment .\n OUTPUT:\n" }, { "from": "agent", "value": "activating invasion and metastasis;resisting cell death;tumor promoting inflammation;sustaining proliferative signaling" } ]

MACC1 also regulates c-met expression . The aim of this study is to explore the expressions of MACC1 and hepatocyte growth factor receptor ( c-met ) , and its relationship with invasion , metastasis , and prognosis of non-small cell lung cancer ( NSCLC ) . METHODS MACC1 and c-met expressions were detected in 103 cases of NSCLC and 40 cases of neighboring normal lung cancer tissue using immunohistochemistry . RESULTS MACC1 and c-met expressions were significantly higher in lung cancer tissues than that in neighboring normal tissue ( P<0.001 ) . MACC1 and c-met expressions were associated with poor differentiation , advanced T stages , lymph node metastasis , and advanced TNM stages ( P<0.05 ) of NSCLC , but not with sex , age , smoking , and histological classification ( P>0.05 ) . In addition , a positive correlation between MACC1 and c-met expressions was observed ( r=0.403 , P<0.001 ) . The result from the Kaplan-Meier survival analysis showed that the five-year survival rate in patients with positive MACC1 and c-met expressions was remarkanly lower than that in patients with negative expressions ( P<0.05 ) . The result from the Cox regression analysis showed that MACC1 expression was an independent prognostic factor for NSCLC ( P=0.026 ) . CONCLUSIONS MACC1 and c-met have an important function in the differentiation , invasion , and metastasis of NSCLC . MACC1 and c-met have poor prognosis in patients with NSCLC .

Sex hormone-binding globulin ( SHBG ) binds and transports sex steroids in the blood , regulating their bioavailable fraction and access to target cells . It can also inhibit the estradiol-induced proliferation of breast cancer cells through its membrane receptor . Three coding-region polymorphisms , which lead to an amino acid change , have been reported . We studied the influence of these three polymorphisms on breast cancer risk in three different populations : Polish familial breast cancer cases , 27% of them carrying a BRCA1/BRCA2 mutation , Nordic familial and sporadic breast cancer cases . The reported G to A polymorphism in exon 1 was not found in the 423 analyzed samples . Instead , we found a C to T transition causing an arg to cys amino acid change within the same codon in one Polish breast cancer patient and her daughter . Both of them were heterozygotes for the exon 8 G to A polymorphism as well . They were diagnosed for bilateral breast cancer and carried a BRCA1 mutation ( 5382insC ) . Analysis of the tumor samples showed that they had lost the wild-type allele both at exons 1 and 8 of the SHBG gene . Analysis of the other Polish samples showed no correlation of the exon 8 polymorphism to breast cancer , bilateral breast cancer , BRCA1/BRCA2 mutations or age at diagnosis . No association of the exon 8 polymorphism with breast cancer in the Nordic familial or sporadic cases was found . The C to T polymorphism located in exon 4 was rare in all the studied populations ( overall allele frequency 0.011 ) . However , in each of the study populations there was a trend for a lower variant allele frequency in cancer cases than in controls . Variant allele frequency in all the breast cancer cases was significantly lower than in all the controls ( chi(2) = 5.27 , P-value 0.02 ; odds ratio = 0.23 , 95% confidence interval 0.05-0.84 ) .\n OUTPUT:\n" }, { "from": "agent", "value": "genomic instability and mutation" } ]

Research focused on proteins that regulate abnormal angiogenesis has attracted intense interest in both academia and industry . Such proteins are able to target several angiogenic factors concurrently , thereby increasing the possibility of therapeutic success . Aquaporin-1 ( AQP1 ) is a water channel membrane protein that promotes tumour angiogenesis by allowing faster endothelial cell migration . In this study we test the hypothesis that AQP1 inhibition impairs tumour growth in a mouse model of melanoma . After validating the inhibitor efficacy of two different AQP1 specific siRNAs in cell cultures , RNA interference experiments were performed by intratumoural injections of AQP1 siRNAs in mice . After 6 days of treatment , AQP1 siRNA treated tumours showed a 75 % reduction in volume when compared to controls . AQP1 protein level , in AQP1 knockdown tumours , was around 75 % that of the controls and was associated with a significant 40 % reduced expression of the endothelial marker , Factor VIII . Immunofluorescence analysis of AQP1 siRNA treated tumours showed a significantly lower microvessel density . Time course experiments demonstrated that repeated injections of AQP1 siRNA over time are effective in sustaining the inhibition of tumour growth . Finally , we have confirmed the role of AQP1 in sustaining an active endothelium during angiogenesis and we have shown that AQP1 reduction causes an increase in VEGF levels . In conclusion , this study validates AQP1 as a pro-angiogenic protein , relevant for the therapy of cancer and other angiogenic-related diseases such as psoriasis , endometriosis , arthritis and atherosclerosis .\n OUTPUT:\n" }, { "from": "agent", "value": "inducing angiogenesis" } ]

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

The present study was intended to verify the effect of IL-28A on the migration of UMUC-3 bladder cancer cells . IL-28A and its receptor IL-28AR1 mRNA were detected in UMUC-3 cells . Although exogenous IL-28A showed no effect on cell proliferation , a wound-healing migration assay showed that the migration of UMUC-3 cells was induced by IL-28A . Furthermore , treatment of the cells with IL-28A significantly promoted MMP-9 expression via binding activities of NF-κB and AP-1 . IL-28A also induced the activation of p38MAPK and Jak2-Stat2 signaling . Using the p38MAPK inhibitor SB203580 and the dominant-negative plasmid DN-p38 , we found evidence that the inhibition of p38MAPK signaling suppressed the effects of IL-28A including wound-healing migration and MMP-9 expression by activation of NF-κB and AP-1 binding in UMUC-3 cells . However , Jak-2 inhibition by AG490 did not affect IL-28A-induced migration of UMUC-3 cells . Collectively , we suggest for the first time that the p38MAPK pathway mediates IL-28A-induced cell migration through MMP-9 expression by activating NF-κB and AP-1 binding motifs .\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling;activating invasion and metastasis" } ]

Here we report that induction of mitochondrial respiratory defect by tetracycline-controlled expression of a dominant negative form of DNA polymerase γ causes a metabolic shift from oxidative phosphorylation to glycolysis and increases ROS generation . We show that upregulation of NOX is critical to support the elevated glycolysis by providing additional NAD+ . The upregulation of NOX is also consistently observed in cancer cells with compromised mitochondria due to the activation of oncogenic Ras or loss of p53 , and in primary pancreatic cancer tissues . Suppression of NOX by chemical inhibition or genetic knockdown of gene expression selectively impacts cancer cells with mitochondrial dysfunction , leading to a decrease in cellular glycolysis , a loss of cell viability , and inhibition of cancer growth in vivo . Our study reveals a previously unrecognized function of NOX in cancer metabolism and suggests that NOX is a potential novel target for cancer treatment .\n OUTPUT:\n" }, { "from": "agent", "value": "cellular energetics;tumor promoting inflammation" } ]

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

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" } ]

The transcription factor c-MYC has been recently shown to regulate in vitro human macrophage polarization and be expressed in macrophages infiltrating human tumors . In this study , we exploited the predominant expression of LysM in myeloid cells to generate c-Myc(fl/fl) LysM(cre/+) mice , which lack c-Myc in macrophages , to investigate the role of macrophage c-MYC expression in cancer . Under steady-state conditions , immune system parameters in c-Myc(fl/fl) LysM(cre/+) mice appeared normal , including the abundance of different subsets of bone marrow hematopoietic stem cells , precursors and circulating cells , macrophage density , and immune organ structure . In a model of melanoma , however , TAMs lacking c-Myc displayed a delay in maturation and showed an attenuation of pro-tumoral functions ( e.g. , reduced expression of VEGF , MMP9 , and HIF1α ) that was associated with impaired tissue remodeling and angiogenesis and limited tumor growth in c-Myc(fl/fl) LysM(cre/+) mice . Macrophage c-Myc deletion also diminished fibrosarcoma growth . These data identify c-Myc as a positive regulator of the pro-tumoral program of TAMs and suggest c-Myc inactivation as an attractive target for anti-cancer therapy .\n OUTPUT:\n" }, { "from": "agent", "value": "avoiding immune destruction" } ]

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

The Ras oncogene is frequently activated or mutated in human cancers , but Ras activation is insufficient to transform primary cells . Ina search for cooperating oncogenes , we identify the lysine demethylase JMJD2A/KDM4A . We show that JMJD2A functions as a negative regulator of Ras-induced senescence and collaborates with oncogenic Ras to promote cellular transformation by negatively regulating the p53 pathway . We find CHD5 , a known tumor suppressor regulating p53 activity , as a target of JMJD2A . The expression of JMJD2A inhibits Ras-mediated CHD5 induction leading to a reduced activity of the p53 pathway . In addition , we show that JMJD2A is overexpressed inmouse and human lung cancers . Depletion of JMJD2A in the human lung cancer cell line A549 bearing an activated K-Ras allele triggers senescence .

More detailed information on inflammatory pathways and the role of neutrophils herein is a prerequisite for understanding the mechanism of inflammation associated cancer . METHODS In the present study , we used microarrays in order to obtain a global view of the transcriptional responses of the lung to LPS in mice , which mimics an acute lung inflammation . To investigate the influence of neutrophils in this process , we depleted mice from circulating neutrophils by treatment with anti-PMN antibodies prior to LPS exposure . RESULTS A total of 514 genes was greater than 1.5-fold differentially expressed in the LPS induced lung inflammation model. 394 of the 514 were up regulated genes mostly involved in cell cycle and immune/inflammation related processes , such as cytokine/chemokine activity and signalling . Down regulated genes represented nonimmune processes , such as development , metabolism and transport . Notably , the number of genes and pathways that were differentially expressed , was reduced when animals were depleted from circulating neutrophils , confirming the central role of neutrophils in the inflammatory response . Furthermore , there was a significant correlation between the differentially expressed gene list and the promutagenic DNA lesion M1dG , suggesting that it is the extent of the immune response which drives genetic instability in the inflamed lung . Several genes that were specifically regulated by the presence of activated neutrophils could be identified and these were mostly involved in interferon signalling , oxidative stress response and cell cycle progression . The latter possibly refers to a higher rate of cell turnover in the inflamed lung with neutrophils , suggesting that the neutrophil influx is associated with a higher risk for the accumulation and fixation of mutations . CONCLUSION Gene expression profiling identified specific genes and pathways that are related to neutrophilic inflammation and could be associated to cancer development and indicate an active role of neutrophils in mediating the LPS induced inflammatory response in the mouse lung .\n OUTPUT:\n" }, { "from": "agent", "value": "tumor promoting inflammation;genomic instability and mutation" } ]

In the studies presented here , we have examined this hypothesis using two human renal carcinoma cell lines , SKRC-4 and SKRC-29 . We demonstrated that both SKRC-4 and SKRC-29 cells were growth stimulated by greater than 35% when cultured in the presence of TGF-alpha or EGF and were inhibited by 29% to 46% if cultured in the presence of anti-EGF-R monoclonal antibody 225 . Treatment of cells with TGF-alpha enhanced the levels of expression of EGF-R mRNA and TGF-alpha mRNA . In addition , incubation of cells with monoclonal antibody 225 significantly elevated the levels of excreted TGF-alpha species in the culture medium . Our findings suggest that proliferation of human renal carcinoma cells may be regulated by endogenously produced TGF-alpha and that this regulatory pathway can be interrupted using antibody to its receptor , EGF-R .\n OUTPUT:\n" }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

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 . Arsenite-induced alteration of energy production in human cells represents the type of fundamental perturbation that could extend to many tissue targets and diseases .\n OUTPUT:\n" }, { "from": "agent", "value": "cellular energetics" } ]

However , their adverse effects on human health have not been fully investigated . In this study , iron oxide nanoparticles were prepared using inorganic iron chloride ( size : 5.3+/-3.6 nm in phosphate buffered saline , surface charge : 23.14 mV ) , and their inflammatory responses were investigated . When mice were treated with iron oxide nanoparticles ( 250 microg/kg , 500 microg/kg , and 1mg/kg ) by a single intratracheal instillation , the level of intracellular reduced glutathione ( GSH ) was decreased in the cells of bronchoalveolar lavage ( BAL ) fluid . The arrest of cell cycles in G1 phase was observed , but S-phase was significantly decreased . The concentrations of pro-inflammatory cytokines ( IL-1 , TNF-alpha , and IL-6 ) were dose-dependently increased at day 1 after instillation in the BAL fluid and in the blood . During the experimental period of 28 days , pro-inflammatory cytokines ( IL-1 , TNF-alpha , and IL-6 ) , Th0 cytokine ( IL-2 ) , Th1 type cytokine ( IL-12 ) , Th2 type cytokines ( IL-4 and IL-5 ) , TGF-beta , and IgE were also elevated . Expressions of many genes related with inflammation or tissue damage such as heat shock protein , matrix metalloproteinase , tissue inhibitors of metalloproteinases , and serum amyloid A were significantly induced . Formation of microgranuloma , which is one of the indicators for chronic inflammatory response , was observed in the alveolar space . In addition , distribution of B cell and CD8+ T cell in blood lymphocytes was increased at day 28 .

Recently , this cell line was shown to harbor multiple copies of a gammaretrovirus , called XMRV , integrated in its genome . While the original prostate cancer xenograft CWR22 is free of any retrovirus , subsequently generated cell lines 22Rv1 and CWR-R1 , carry this virus and additionally shed infectious gammaretroviral particles in their supernatant . Although XMRV most likely was generated by recombination events in cell culture this virus has been demonstrated to infect human cells in vitro and 22Rv1 as well as CWR-R1 cells are now considered biosafety 2 reagents . Here , we demonstrate that 22Rv1 cells with reduced retroviral transcription show reduced tumor angiogenesis and increased necrosis of the primary tumor derived from xenografted cells in scid mice when compared to the parental cell line . The presence of XMRV transcripts significantly increases secretion of osteopontin ( OPN ) , CXCL14 , IL13 and TIMP2 in 22Rv1 cells . Furthermore , these data are supported by in vitro cell invasion and differentiation assays . Collectively , our data suggest that the presence of XMRV transcripts at least partially contributes to 22Rv1 characteristics observed in vitro and in vivo with regard to migration , invasion and tumor angiogenesis .

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

The effects of inhibiting glycolysis using metabolic inhibitors iodoacetate ( IAA ) , an inhibitor of GAPDHase , and 3-bromopyruvate ( 3BP ) , an inhibitor of hexokinase-II , on survival and signaling of pancreatic cancer cells ( Panc-1 ) were investigated . MATERIALS AND METHODS Cellular survival was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide ( MTT ) assay . Lactate dehydrogenase ( LDH ) assay was used to analyze the induced necrosis and protein levels were evaluated using Western blot analysis . RESULTS The results show that the inhibitors lowered cellular survival and increased cellular necrosis . Mitogenic signaling pathways were affected by 3BP but not by IAA . CONCLUSION We conclude that there may be a cross-talk between signaling pathways and glycolysis in regulating pancreatic cancer cell survival and signaling . Thus , a combination of agents that inhibit both energy production and cell signaling may provide a novel and effective approach to target pancreatic cancer effectively .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death;cellular energetics" } ]

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

Using stable retroviral transduction , we evaluated the consequences of BMI-1 knockdown on the growth of CDKN2A wild-type and mutant ESFT cells in subconfluent and confluent conditions . Although knockdown of BMI-1 had no effect on proliferation in low-density cultures , at high cell densities it resulted in cell cycle arrest and death . The normal cell contact inhibition response is mediated , in large part , by the recently described Hippo pathway which functions to inhibit cell proliferation and promote cell death by inactivating the Yes-Associated Protein ( YAP ) . Significantly , we found that YAP levels , activity and expression did not diminish in confluent ESFT cells that expressed high levels of BMI-1 . In contrast , YAP expression and nuclear localization were reduced in confluent BMI-1 knockdown cells suggesting that silencing of BMI-1 restored contact inhibition by restoring normal activation of the Hippo-YAP growth-suppressor pathway . Importantly , knockdown of YAP in ESFT cells resulted in profound inhibition of cell proliferation and anchorage-independent colony formation suggesting that stabilization and continued expression of YAP is critical for ESFT growth and tumorigenicity . Together , these studies reveal a previously unrecognized link between BMI-1 , contact inhibition and the Hippo-YAP pathway and suggest that resistance to contact inhibition in BMI-1 overexpressing cancer cells may be in part a result of Hippo inhibition and aberrant stabilization of YAP .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors" } ]

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

MATERIALS AND METHODS In four PCa cell lines ( LNCaP , 22RV1 , PC3 , DU145 ) and two reference cell lines 5HTR1a and -1b , relative mRNA expression levels were assessed . Different serotonin and MLT receptor agonists and antagonists were used in stimulation and inhibition experiments . RESULTS mRNA expression of 5HTR1b was higher than that of 5HTR1a in all PCa cell lines . Serotonin showed a significant growth stimulatory effect in all PCa lines . The 5HTR1a and -1b agonists/antagonists did not significantly affect viability . MLT inhibited viability only in PC3 cells . Similarly , the 5HTR1a antagonist induced apoptotic changes in PC3 cells only at 10(-4)M , while the 5HTR1b antagonist induced necrosis at 10(-4)M in all cell lines . Cell cycle alterations were seen in PC3 and DU145 cells under the influence of the 5HTR1a antagonist . CONCLUSIONS Serotonin receptor antagonists and agonists as well as MLT influence viability and apoptosis of PCa cell lines at supraphysiologic concentrations . In contrast to other reports , our results do not support a regulatory role of serotonin or MLT receptor activation or inhibition in PCa growth .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death" } ]

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" } ]

Pneumothorax occurring as a complication of vascular endothelial growth factor receptor ( VEGFR ) inhibitor therapy has not been previously described in the medical literature . Sunitinib malate is a VEGFR inhibitor approved for the treatment of advanced renal cell carcinoma . We present a patient with metastatic renal cell carcinoma manifested as bilateral pulmonary nodules who developed a bilateral spontaneous pneumothorax 3 weeks after initiation of sunitinib therapy . We believe that sunitinib therapy resulted in necrosis of multiple pleural-based pulmonary nodules with central cavernization and ultimately rupture with bronchopleural fistula formation . Based on this experience , we advise that practitioners exercise caution when prescribing anti-VEGFR therapy in patients with pleural-based pulmonary metastases and recognize that the efficacy and toxicity of these agents may be closely linked .\n OUTPUT:\n" }, { "from": "agent", "value": "resisting cell death" } ]

It is reported that the risk of skin cancer in humans increases by the depletion of the ozone layer . We have examined the genotoxicity of solar ultraviolet , especially the longer wavelength light , using Drosophila . Recently , we have demonstrated that light of wavelength up to 340 nm is mutagenic on Drosophila larvae . Using an excision repair-deficient Drosophila strain ( mus201 ) , we have obtained results suggesting that the lesion caused in larvae by the 320 nm-light irradiation may be similar to the damage induced by irradiation at 310 nm , and that light of 330 and 340 nm may induce damage different from that induced by 310 and 320 nm-light . To examine the difference in DNA damage induced by light of a particular wavelength , we performed monochromatic irradiation on larvae of two Drosophila strains ; one excision repair-deficient ( mei-9 ) and another postreplication repair-deficient ( mei-41). 310 and 320 nm-light was more mutagenic in the mei-9 strain than in mei-41 , whereas 330 and 340 nm-light was more mutagenic in mei-41 than in mei-9 . It is demonstrated that the mei-41 gene is a homologue of the human atm gene which is responsible for a cell cycle checkpoint . This result suggests that 310-320 nm-light induces DNA damage that is subject to nucleotide excision repair ( NER ) and that 330-360 nm-light causes damage to be recognized by the cell cycle checkpoint but it is not repairable by NER .\n OUTPUT:\n" }, { "from": "agent", "value": "evading growth suppressors;genomic instability and mutation" } ]

The aim of this work was to study the u-PA production , in vitro and in vivo , in a transplantable murine mammary adenocarcinoma ( M3 ) , moderately metastatic to lung , and in a related tumor variant ( MM3 ) , highly metastatic to the same organ , during tumor development . At different times post-transplantation , tumors were employed to prepare either primary cell cultures or homogenates . PA activity from conditioned media ( CM ) , cell lysates ( CLs ) and tumor homogenates ( THs ) was quantitated by means of a fibrinolytic assay . Immunoneutralization and zymographic assays were performed to identify the PA present in both tumors . PA activity in CM , CLs and THs , that was undetectable at early stages , increased significantly along the growth of M3 adenocarcinoma . Secreted PA activity in MM3 CM was measurable at early stages and consistently increased up to 37 days post-transplantation , but a marked fall of activity was found at 48 days . PA activity in MM3 THs exhibited the same enhancement and late fall found in vitro . A positive correlation was observed between tumor size and THs PA values in both tumors . The PA present in cell cultures and THs was identified as of the u-PA type . These results support the hypothesis that high u-PA levels are important for tumor invasion and that the stage of tumor development is a critical factor in their PA activity .\n OUTPUT:\n" }, { "from": "agent", "value": "activating invasion and metastasis" } ]

METHODS Selected were 30-week-old HER2/neu transgenic spontaneous breast cancer mice FVB/neu . The primary tumor resection was carried out . After surgery they were randomly divided into the blank control group , the RSR group , the Herceptin group , and the combination group ( RSR + Herceptin group ) . The treatment lasted for 4 months . The inhibition rate of the recurrent tumor volume and the inhibition rate of the lung metastasis were evaluated . The expressions of matrix metalloproteinase-2 ( MMP-2 ) , matrix metalloproteinase-9 ( MMP-9 ) , tissue inhibitor of metalloproteinase ( TIMP-1 ) , and TIMP-2 in the recurrent tumor tissue were detected using Western blot . RESULTS By the end of the treatment the average recurrent tumor volume was 11.11 +/- 8.71 cm3 in the blank control group and 5.56 +/- 5.55 cm3 of the RSR group , showing statistical difference between the two groups ( P = 0.037 ) . The average lung metastatic nodule was 16 in the blank control group and 10 in the RSR group . The inhibition rate of lung metastasis was 37. 85% in the RSR group , but with no statistical significance . The expression level of activated MMP-2 in the RSR group was down-regulated when compared with the blank control group , the Herceptin group , and the combination group ( P &lt ; 0.05 ) . The expression of MMP-9 of the RSR group , the Herceptin group , and the combination group was significantly down-regulated when compared with the blank control group ( P &lt ; 0.05 ) . The expression of MMP-9 of the RSR group and the combination group was further down-regulated when compared with the Herceptin group ( P &lt ; 0.05 ) . The expressions of both TIMP-1 and TIMP-2 of the RSR group , the Herceptin group , and the combination group were all up-regulated when compared with the blank control group ( P &lt ; 0.05 ) . The increased expression of TIMP-1 was more significantly in the RSR group and the combination group when compared with the Herceptin group ( P &lt ; 0.05 ) . It was higher in the combination group than in the RSR group ( P &lt ; 0.05 ) . CONCLUSIONS RSR could inhibit the tumor recurrence of FVB/neu mice . It could reduce the degradation of extracellular matrix and increase the protective effects of extracellular matrix . It might achieve its anti-tumor effect through effecting the invasive and metastatic capabilities of breast tumor cells .\n OUTPUT:\n" }, { "from": "agent", "value": "activating invasion and metastasis" } ]

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