In colorectal cancer ( CRC ) , previous studies evaluating the relationship between TYMP expression and clinicopathological features have yielded inconsistent results . The aim of this study was to investigate the prognostic value of TYMP , its association with other angiogenic factors , proliferation markers and , to our knowledge , for the first time its relationship with extracellular matrix components . MATERIALS AND METHODS Formalin-fixed , paraffin-embedded specimens from 97 patients with CRC were immunostained for TYMP , vascular endothelial growth factor ( VEGF ) , microvascular density ( CD34 ) , proliferation marker ( Ki-67 ) , proliferating cell nuclear antigen ( PCNA ) , p53 oncoprotein and extracellular matrix components ( collagen type IV , fibronectin , tenascin and laminin ) . Survival curves were calculated with the Kaplan-Meier method . RESULTS Immunoreactivity was observed in the cytoplasm ( cyt ) and nucleus ( n ) of the tumor cells , as well in the stroma ( st ) , endothelium and tumor-associated macrophages . High TYMPcyt expression was observed in 7.2% of the cases , moderate in 22.7% and weak in 59.9% , while 10.3% were negative . High TYMPst expression was observed in 58.8% of the cases . TYMPcyt expression was correlated with the VEGF expression of tumor cells and VEGF expression of vessels ( p=0.014 and p=0.022 , respectively ) . TYMPst expression was correlated with VEGF expression and tenascin ( p=0.014 and p=0.011 , respectively ) . Patients with higher TYMPcyt expression had a more favorable overall survival ( p=0.041 ) in univariate analysis compared to patients without TYMP expression . CONCLUSION These findings suggest that TYMP plays an important role in angiogenesis , extracellular matrix remodeling and in the prognosis of patients with CRC , but further studies are needed to clearly define its role in CRC .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

The therapeutic effects of certain anti-myeloma drugs are partially mediated by targeting the innate immune response . In addition , novel types of natural compounds have been developed that efficiently modulate the activity of both the cellular and humoral compartments of immunity . MGN-3 is known as an activator of natural killer cells , inducer of apoptosis and cytokine production , and modulator of dendritic cell maturation and differentiation in vitro . We have performed a randomized , placebo-controlled study to examine the effects of MGN-3 on innate immune system parameters in 48 multiple myeloma patients . We performed immunophenotypic analysis of peripheral blood samples , determined NK cell activity , and assessed the cytokine profiles of plasma before and during 3months of treatment . The results demonstrate a clear increase in NK activity in MGN-3-treated patients compared to the placebo group , an increased level of myeloid DCs in peripheral blood , and augmented concentrations of T helper cell type 1-related cytokines . The present study suggests that MGN-3 may represent an immunologically relevant product for activating innate immunity in multiple myeloma patients and warrants further testing to demonstrate clinical efficacy .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

P53-dependent molecular mediators of the Warburg effect reduce glucose consumption and promote mitochondrial function . We therefore hypothesized that the retention of wild-type p53 characteristic of primary glioblastomas limits metabolic demands induced by deregulated signal transduction in the presence of hypoxia and nutrient depletion . Here we report that short hairpin RNA-mediated gene suppression of wild-type p53 or ectopic expression of mutant temperature-sensitive dominant-negative p53(V135A) increased glucose consumption and lactate production , decreased oxygen consumption and enhanced hypoxia-induced cell death in p53 wild-type human glioblastoma cells . Similarly , genetic knockout of p53 in HCT116 colon carcinoma cells resulted in reduced respiration and hypersensitivity towards hypoxia-induced cell death . Further , wild-type p53 gene silencing reduced the expression of synthesis of cytochrome c oxidase 2 ( SCO2 ) , an effector necessary for respiratory chain function . An SCO2 transgene reverted the metabolic phenotype and restored resistance towards hypoxia in p53-depleted and p53 mutant glioma cells in a rotenone-sensitive manner , demonstrating that this effect was dependent on intact oxidative phosphorylation . Supplementation with methyl-pyruvate , a mitochondrial substrate , rescued p53 wild-type but not p53 mutant cells from hypoxic cell death , demonstrating a p53-mediated selective aptitude to metabolize mitochondrial substrates . Further , SCO2 gene silencing in p53 wild-type glioma cells sensitized these cells towards hypoxia . Finally , lentiviral gene suppression of SCO2 significantly enhanced tumor necrosis in a subcutaneous HCT116 xenograft tumor model , compatible with impaired energy metabolism in these cells . These findings demonstrate that glioma and colon cancer cells with p53 wild-type status can skew the Warburg effect and thereby reduce their vulnerability towards tumor hypoxia in an SCO2-dependent manner . Targeting SCO2 may therefore represent a valuable strategy to enhance sensitivity towards hypoxia and may complement strategies targeting glucose metabolism .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

We investigated the hypothesis that the tissue expression of three cell cycle markers , Rb , p21 and p16 , would provide helpful prognostic information in a well characterised series of prostate cancers which were clinically localised and treated conservatively . METHODS The immunohistochemical staining expression of these markers was assessed in tissue microarrays and correlated with 10 year prostate cancer survival and overall survival and then compared with pathological data including contemporary Gleason score , age , measures of tumour extent and initial serum prostate specific antigen ( PSA ) level . RESULTS Rb overexpression did not show any significant association with Gleason score or prostate cancer survival. p21 protein expression showed a significant association with prostate cancer survival ( p = 0.02 ) and overall survival ( p = 0.01 ) in a univariate model but not in a multivariate model with pathological and serum PSA data . There was a significant association between p16 cytoplasmic expression and prostate cancer survival ( HR = 2.52 , 95%CI = 1.79-3.55 , p < 0.001 ) and overall survival ( HR = 1.54 , 95% CI = 1.20-1.98 , p = 0.001 ) in a univariate model. p16 expression remained an independent prognostic factor for prostate cancer survival ( HR = 1.50 , 95%CI = 1.05-2.14 , p = 0.03 ) . CONCLUSION We conclude that p16 cytoplasmic expression can be used as a predictor of outcome in conservatively treated prostate cancer . Rb and p21 show no independent association with outcome and therefore further research is not warranted .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

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" } ]

This effect has been attributed to IFN-γ preventing tumor stroma formation but not to a direct effect on the cancer cells . However , it is not known , which influence IFN-γ has on tumors with an established stroma . To address this question , the plasmacytoma cell line J558L was transduced with a vector allowing doxycycline-inducible IFN-γ gene expression . After the injection of the tumor cells into mice , IFN-γ was induced at different time points . Tumors did not grow when inducing IFN-γ immediately after tumor cell inoculation , while approximately half of the tumors were rejected when IFN-γ was induced in early established tumors within 2 weeks . Induction of IFN-γ 2-3 weeks after tumor cell inoculation was less efficient ( 0-17% rejection ) . IFN-γ induction in established tumors led to a reduction of CD146(+) endothelial cells and massive necrosis . Together , we show that vascularized tumors can be rejected by local IFN-γ expression , but that rejection of established tumors was less efficient over time . This suggests that transplanted tumors became less susceptible to local IFN-γ treatment the better they are established .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;inducing angiogenesis" } ]

Deregulated activity of Wnt growth factors resulting from overexpression of the Wnt inhibitor Dickkopf-1 ( DKK-1 ) is known to contribute to formation of the osteoblastic component of PCa skeletal bone metastases . In this study , we report that DKK-1 knockdown in osteolytic human PCa cells unexpectedly delays the development of both soft tissue and osseous lesions . PCa cells deficient in DKK-1 expression did not increase canonical Wnt signaling in target osteoblast cell lines ; however , DKK-1 knockdown PCa cells exhibited increased expression of the CDK inhibitor p21(CIP1/WAF1) and a 32% increase in G(1) arrest compared with control cells . Ablating p21(CIP1/WAF1) in PCa cells deficient in DKK-1 was sufficient to rescue tumor growth . Collectively , our findings demonstrate that DKK-1 overexpression supports tumor growth in part by restricting expression of p21(CIP1/WAF1) through a mechanism independent of canonical Wnt signaling .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors" } ]

To investigate a possible causal role of EGF receptor expression in breast cancer progression to hormone independence , we have created an experimental cell system . Epidermal growth factor receptor complementary DNA was introduced in estrogen-dependent ZR-75-1 breast cancer cells , and the resulting ZR/HERc cells exhibited a mitogenic response to epidermal growth factor , thus bypassing estrogen dependence . This EGF-induced proliferation could not be inhibited by antiestrogens . In addition , we noted changes in cell morphology and keratin expression of EGF-stimulated ZR/HERc cells , suggestive of an altered differentiation state . Furthermore , intolerance of functional ER and EGF receptor signal transduction pathways in ZR/HERc cells was observed during simultaneous activation , which possibly explains the inverse relationship of ER and EGF receptor expression in primary tumors . In contrast to the parental cells , ZR/HERc cells rapidly progressed to a stable ER-negative phenotype when cultured in the presence of the antiestrogen hydroxy-tamoxifen . These results suggest a possible role for EGF receptor in progression of breast cancer to hormone independence .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

The mechanism by which EGFR inhibition functions is unclear , with controversial results demonstrating an effect on the tumor cells , endothelial cells , or pericytes . EGFR activation has been linked to the expression of vascular endothelial growth factor ( VEGF ) , a known mitogen of angiogenesis , but the relationship between these factors and their effect on tumor vessel development is vague . We hypothesized that using an EGFR inhibitor on a human Ewing's sarcoma model would inhibit tumor growth by suppressing vessel proliferation . METHODS A cell proliferation assay was performed on the Ewing's sarcoma ( SK-NEP-1 ) cell line . Tumor cells were implanted intrarenally in athymic mice . Animals received daily gavage with vehicle or gefitinib 1 wk following implantation . Mice ( n = 12/cohort ) were euthanized 6 wk following implantation . Remaining mice were maintained without treatment for 2 wk . Vascular changes were assessed by angiography and immunohistochemically . EGFR and vascular endothelial growth factor ( VEGF ) expression were quantified using quantitative polymerase chain reaction ( qPCR ) . RESULTS Gefitinib suppressed in vitro cell growth with an IC(50) = 1.36 μM . Minimal tumor growth suppression was noted at 6 wk ( 6.01 � 1.2 g in control versus 4.61 � 0.9 g treated , P = 0.36 ) . After cessation of gefitinib , tumor growth was increased in both groups ( 7.37 � 1.62 g versus 6.77 � 1.53 g , P = 0.79 ) . Microvessel density was unchanged despite EGFR inhibition ( 161,000 � 16,000 pixels versus 135,000 � 18,000 pixels , P = 0.31 ) . At 6 wk , the vascular maturity index was similar in both groups ( 3.63 � 1.12 versus 4.09 � 1.71 , P = 0.83 ) . A downward trend in EGFR expression ( 49% of control ) and an upward trend in VEGF levels ( 50% of control ) occurred in the treated group . CONCLUSIONS EGFR expression was suppressed in cultured cells and xenograft tumors . Despite a cytotoxic effect on cell lines , gefitinib had little effect on tumor growth . No effects on the tumor vasculature were noted in the setting of EGFR suppression , suggesting that angiogenesis induced by SK-NEP-1 cells is refractory to EGFR inhibition . Interestingly , the resulting increase in VEGF expression following EGFR blockade , provides an alternative pro-angiogenic pathway promoting tumor survival .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;inducing angiogenesis" } ]

Little is known about the synergistic action of growth and inflammatory factors in IBDC metastases . METHODS The expression of activated extracellular signal-regulated kinase1/2 ( phosphorylated or p-ERK1/2 ) was analyzed by immunohistochemistry in IBDC tissue samples from 80 cases . BT474 IBDC cell migration and invasion were quantified using the Transwell assay . Matrix metalloproteinase ( MMP)-9 expression and activity were analyzed by RT-PCR , Western blotting and zymography . Activator protein ( AP)-1 activity was measured with a luciferase reporter gene assay . The Wilcoxon signed-rank test , Chi-square test , the partition of Chi-square test , independent t-test , and Spearman's method were used for the statistical analysis . RESULTS Phosphorylated ERK1/2 was detected in 58/80 ( 72.5% ) IBDC tissues , and was associated with higher TNM stage and lymph node metastasis , but not patient age or tumor size . Individually , epidermal growth factor ( EGF ) , and interleukin ( IL)-1β activated ERK1/2 , increased cell migration and invasion , MMP-9 expression and activity , AP-1 activation in vitro and the expression of p-ERK1/2 was positively correlated with EGF expression levels , as well as IL-1β , MMP-9 and c-fos in IBDC tissue samples . Co-stimulation with EGF and IL-1β synergistically increased ERK1/2 and AP-1 activation , cell migration and invasion , and MMP-9 expression and activity . Inhibition of ERK1/2 using U0126 or siRNA abolished EGF and/or IL-1β-induced cell migration and invasion in a dose-dependent manner . CONCLUSION Activated ERK1/2 was associated with higher TNM stage and lymph node metastasis in IBDC . Both in vitro and in vivo studies indicated that ERK-1/2 activation may increase the metastatic ability of IBDC cells . Growth and inflammatory factors synergistically induced IBDC cell migration and invasion via ERK1/2 signaling , AP-1 activation and MMP-9 upregulation .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;sustaining proliferative signaling;tumor promoting inflammation" } ]

Because ginseng has been shown to inhibit angiogenesis and matrix metalloproteinase ( MMP ) activity , we hypothesized that adipose tissue growth and obesity can be regulated by Korean ginseng ( Panax ginseng C.A. Meyer ) . Wild-type C57BL/6J mice were fed for 8 weeks with a low fat diet , a high fat diet ( HFD ) , or HFD supplemented with 0.5% or 5% Korean red ginseng extract . We measured body weight , adipose tissue mass , food intake , MMP activity , and the expression of genes involved in angiogenesis and MMPs . Administering ginseng to HFD-induced obese mice produced reductions in body weight and adipose tissue mass compared with untreated counterparts . Ginseng treatment decreased blood vessel density and MMP activity in adipose tissues . Ginseng also reduced mRNA levels of angiogenic factors ( e.g. , VEGF-A and FGF-2 ) and MMPs ( e.g. , MMP-2 and MMP-9 ) , whereas it increased mRNA levels of angiogenic inhibitors ( e.g. , TSP-1 , TIMP-1 , and TIMP-2 ) in adipose tissues . These results demonstrate that ginseng effectively reduces adipose tissue mass and prevents obesity in diet-induced obese mice and that this process may be mediated in part through the anti-angiogenic actions of ginseng .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis" } ]

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" } ]

The obesity hormone leptin is considered as a key mediator for cancer development and progression . The present study aims to investigate regulatory effects of leptin on colorectal carcinoma . The expression of leptin and its receptor Ob-R was examined by immunohistochemistry in 108 Chinese patients with colorectal carcinoma . The results showed that leptin/Ob-R expression was significantly associated with T stage , TNM stage , lymph node metastasis , distant metastasis , differentiation and expression of p-mTOR , p-70S6 kinase , and p-Akt . Furthermore , the effects of leptin on proliferation and apoptosis of HCT-116 colon carcinoma cells were determined . The results showed that leptin could stimulate the proliferation and inhibit the apoptosis of HCT-116 colon cells through the PI3K/Akt/mTOR pathway . Ly294002 ( a PI3K inhibitor ) and rapamycin ( an mTOR inhibitor ) could prevent the regulatory effects of leptin on the proliferation and apoptosis of HCT-116 cells via abrogating leptin-mediated PI3K/Akt/mTOR pathway .

METHODS The GH3B6 cell proliferation was estimated by BrdU incorporation and the cell cycle progression by flow cytometric cell cycle analysis . We determined the expression of PKCalpha and PKCe in membrane and cytosolic fractions by western blotting . The subcellular redistribution of both PKC isozymes was analyzed by confocal microscopy . RESULTS Incubation with PMA for 15 min stimulated PKCalpha and PKCe activation , which was correlated with the phosphorylation of ERK1/2 but not Akt . The activation of both these PKC isozymes was closely associated with the stimulation of proliferation and the cell cycle progression induced by PMA in GH3B6 cells , an effect that was blocked by the inhibitors of PKCalpha ( Gö6976 ) and PKCe ( eV1-2 ) . In addition , the pretreatment with the inhibitor of ERK1/2 ( PD98059 ) prevented the mitogenic activity induced by treatment with PMA for 15 min . CONCLUSION We demonstrated that the activation of PKCalpha and PKCe by phorbol ester in tumor pituitary GH3B6 cells led to cell proliferation and cell cycle progression , effects that involved ERK1/2 activation .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

The presence of these soluble receptors and immunosuppressive cytokines , including interleukin-10 ( IL-10 ) , might be important in the mechanisms of immunosuppression. cis-Diaminedichloroplatinum ( cisplatin ) has been reported to immunomodulate , especially when used in low dose in combination with 5-Fluorouracil ( 5-FU ) . In this study , cisplatin and UFT , a form of uracil and tegafur which is a prodrug of 5-FU , were administered with immunomodulator Polysaccharide K ( PSK ) to ten patients with colorectal cancer , who showed distant metastasis in the liver or lung , and the serum levels of sIL-2R and sTNF-R1 and the production of gamma-interferon ( gamma-INF ) and interleukin-10 by peripheral blood mononuclear cells were measured .

When an adenovirus construct expressing a constitutively active Ras mutant ( Ad/RasG12V ) was infected into HUVECs , their morphology changed strikingly and they appeared to be transformed . However , Ad/RasG12V-infected HUVECs did not enter the S phase , as determined by assessing 3H-thymidine incorporation . In accordance with the above results , the expression of cyclin A both at the transcript and protein levels did not increase in Ad/RasG12V-infected HUVECs relative to that in control cells , although the expression of cyclin D1 was induced in Ad/RasG12V-infected cells . Interestingly , the expression of the cyclin-dependent kinase ( CDK ) inhibitor p21cip1 was remarkably increased while that of p27kip1 did not decrease in Ad/RasG12V-infected HUVECs . Furthermore , CDK2 activity was not induced in Ad/RasG12V-infected HUVECs . These results suggested that the constitutive activation of Ras promoted the reentry of confluent HUVECs in the G0 phase into the G1 phase , but not into the S phase . The results also indicated that the constitutive activation of Ras might have induced the persistent expression of p21cip1 and p27kip1 , and that this induction of p21cip1 and p27kip1 expression possibly caused the cell cycle arrest at the G1 phase .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;evading growth suppressors" } ]

Recent evidence indicates however that senescent cells secrete various growth factors and cytokines , some of which may paradoxically promote cancer progression . This phenomenon termed senescence-associated secretory phenotype ( SASP ) must be inhibited in order for anti-proliferative agents to be effective . The present study was designed to determine whether the β-catenin destruction complex ( BCDC ) , known to integrate the action of various growth factors and cytokines , would represent a suitable target to inhibit the activity of SASP components . For this , we carried out experiments to determine the effect of drug-induced senescence on secretion of SASP , β-catenin transactivation , and the relationship between these processes . Moreover , genetic and pharmacological approaches were used to define the implication of BCDC in mediating the effects of SASP components on cell migration and resistance to drugs . The findings indicate that drug-induced senescence was associated with expression of various Wnt ligands in addition to previously known SASP components . Beta catenin transactivation and expression of genes implicated in epithelial-mesenchymal transition ( EMT ) also increased in response to drug-induced SASP . These effects were prevented by Pyrvinium , a recently described activator of BCDC . Pyrvinium also suppressed the effects of SASP on cell migration and resistance to doxorubicin . Together , these findings provide insights on the potential role of BCDC in mediating the effects of drug-induced SASP on cancer cell invasion and resistance to therapy , and suggest that targeting this pathway may represent an effective approach to enhance the activity of current and prospective anti-cancer therapeutics .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;activating invasion and metastasis" } ]

ZFN introduced targeted DNA double strand breaks ( DSB ) and initiated non-homologous end joining ( NHEJ ) after pronuclear or cytoplasmatic microinjection into zygotes . Resulting frame shift mutations led to functional gene ablations in zebra fish , mice , pigs and also in laboratory rats . Therefore , we targeted the rat Rag1 gene essential for the V(D)J recombination within the immunoglobulin production process and for the differentiation of mature B and T lymphocytes to generate an immunodeficient rat model in the LEW/Ztm strain . RESULTS After microinjection of Rag1 specific ZFN mRNAs in 623 zygotes of inbred LEW/Ztm rats 59 offspring were born from which one carried a 4 bp deletion . This frame shift mutation led to a premature stop codon and a subsequently truncated Rag1 protein confirmed by the loss of the full-length protein in Western Blot analysis . Truncation of the Rag1 protein was characterized by the complete depletion of mature B cells . The remaining T cell population contained mature CD4+/CD3+/TCRαβ+ as well as CD8+/CD3+/TCRαβ+ positive lymphocytes accompanied by a compensatory increase of natural killer cells in the peripheral blood . Reduction of T cell development in Rag1 mutant rats was associated with a hypoplastic thymus that lacked follicular structures . Histological evaluation also revealed the near-complete absence of lymphocytes in spleen and lymph nodes in the immunodeficient Rag1 mutant rat . CONCLUSION The Rag1 mutant rat will serve as an important model for transplantation studies . Furthermore , it may be used as a model for reconstitution experiments related to the immune system , particularly with respect to different populations of human lymphocytes , natural killer cells and autoimmune phenomena .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;avoiding immune destruction" } ]

YAP is a transcriptional coactivator that controls cellular responses through interaction with TEAD transcription factors in the nucleus , while its transcriptional functions are inhibited by phosphorylation-dependent translocation to the cytosol . YAP overexpression has been associated with different types of cancer , such as lung , skin , prostate , ovary and liver cancer . Recently , YAP was linked to E-cadherin-dependent regulation of contact inhibition in breast cancer cells . RESULTS In this study we examined YAP protein expression and cellular localization in 237 cases of human invasive breast cancer by immunohistochemistry and related its expression to clinicopathological features and E-cadherin expression . We observed that invasive lobular carcinoma is characterized by higher expression levels of both nuclear and cytosolic YAP ( p < 0.001 ) . Nuclear YAP expression did not associate with other variables such as lymph node involvement , tumor grade , tumor size , mitotic activity or the molecular sub-types of invasive breast cancer . We observed that high nuclear and cytosolic YAP expression are associated with the E-cadherin deficient breast cancer subtype ILC ( p < 0.001 ) and cell lines derived from human breast cancers and conditional mouse models of human lobular breast cancer . CONCLUSIONS Since our data indicate that nuclear YAP localization is more common in breast cancers lacking functional adherens junctions , it suggests that YAP-mediated transcription may be involved in the development and progression of invasive lobular breast cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

METHODS Cell proliferation enhanced by AFP was detected by MTT assay , 3H-thymidine incorporation and S-stage percentage of cell cycle analysis . With radioactive labeled 125I-AFP for receptor binding assay ; cAMP accumulation , protein kinase A activity were detected by radioactive immunosorbent assay and the change of intracellular free calcium ( Ca2+i ) was monitored by scanning fluorescence intensity under TCS-NT confocal microscope . The expression of oncogenes N- ras , p 53 , and p21( ras ) in the cultured cells in vitro were detected by Northern blotting and Western blotting respectively . RESULTS It was demonstrated that AFP enhanced the proliferation of human hepatoma Bel 7402 cell in a dose dependent fashion as shown in MTT assay , ( 3)H-thymidine incorporation and S-phase percentage up to 2-fold . Two subtypes of AFP receptors were identified in the cells with Kds of 1.3 x 10(-9)mol.L(-1) and 9.9 x10(-8)mol . ( -1)L respectively . Pretreatment of cells with AFP resulted in a significant increase ( 625% ) in cAMP accumulation . The activity of protein kinase A activity were increased up to 37.5 , 122.6 , 73.7 and 61.2% at treatment time point 2 , 6 , 12 and 24 hours . The level of intracellular calcium were elevated after the treatment of alpha-fetoprotein and achieved to 204% at 4 min . The results also showed that AFP(20mg.L(-1)) could upregulate the expression of N- ras oncogenes and p 53 and p21( ras ) in Bel 7402 cells . In the later case,the alteration were 81.1%(12h) and 97.3%(12h) respectively compared with control . CONCLUSION These results demonstrate that AFP is a potential growth factor to promote the proliferation of human hepatoma Bel 7402 cells . Its growth-regulatory effects are mediated by its specific plasma membrane receptors coupled with its transmembrane signaling transduction through the pathway of cAMP-PKA and intracellular calcium to regulate the expression of oncogenes .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

Modulation of HB-EGF activity might have a therapeutic potential in the oncology area . We explored the therapeutic possibilities by characterizing the in vitro biological activity of anti-HB-EGF monoclonal antibody Y-142 . EGF receptor ( EGFR ) ligand and species specificities of Y-142 were tested . Neutralizing activities of Y-142 against HB-EGF were evaluated in EGFR and ERBB4 signaling . Biological activities of Y-142 were assessed in cancer cell proliferation and angiogenesis assays and compared with the anti-EGFR antibody cetuximab , the HB-EGF inhibitor CRM197 , and the anti-vascular endothelial growth factor ( VEGF ) antibody bevacizumab . The binding epitope was determined with alanine scanning . Y-142 recognized HB-EGF as well as the EGFR ligand amphiregulin , and bound specifically to human HB-EGF , but not to rodent HB-EGF . In addition , Y-142 neutralized HB-EGF-induced phosphorylation of EGFR and ERBB4 , and blocked their downstream ERK1/2 and AKT signaling . We also found that Y-142 inhibited HB-EGF-induced cancer cell proliferation , endothelial cell proliferation , tube formation , and VEGF production more effectively than cetuximab and CRM197 and that Y-142 was superior to bevacizumab in the inhibition of HB-EGF-induced tube formation . Six amino acids in the EGF-like domain were identified as the Y-142 binding epitope . Among the six amino acids , the combination of F115 and Y123 determined the amphiregulin cross-reactivity and that F115 accounted for the species selectivity . Furthermore , it was suggested that the potent neutralizing activity of Y-142 was derived from its recognition of R142 and Y123 and its high affinity to HB-EGF . Y-142 has a potent HB-EGF neutralizing activity that modulates multiple biological activities of HB-EGF including cancer cell proliferation and angiogenic activities .

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 .

Epigenetic silencing of the THRB gene is common in human cancers . The aim of the present study was to determine how DNA methylation affected the expression of the THRB gene in differentiated thyroid cancer ( DTC ) and how reexpression of the THRB gene attenuated the cancer phenotypes . We used methylation-specific PCR to examine the expression and promoter methylation of the THRB gene in DTC tissues . Thyroid cancer cells with hypermethylated THRB were treated with the demethylating agents 5'-aza-2'-deoxycytidine ( 5'-aza-CdR ) and zebularine to evaluate their impact on the cancer cell phenotypes . THRB mRNA expression in DTC was 90% lower than in normal controls , and this decrease was associated with a higher tumor/lymph node staging . The promoter methylation level of the THRB gene had a significant negative correlation with the expression level of the THRB gene . Treatment of FTC-236 cells with 5'-aza-CdR or zebularine induced reexpression of the THRB gene and inhibited cell proliferation and migration . FTC-236 cells stably expressing TRβ exhibited lower cell proliferation and migration through inhibition of β-catenin signaling pathways compared with FTC-236 without TRβ. 5'-Aza-CdR also led to suppression of tumor growth in an in vivo xenograft model using FTC-236 cells consistent with the cell-based studies . These finding indicate that TRβ is a tumor suppressor and could be tested as a potential therapeutic target .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;sustaining proliferative signaling" } ]

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 . We propose that data received with 22Rv1 cells or equivalent cells carrying xenotropic gammaretroviruses should be carefully controlled including other prostate cancer cell lines tested for viral sequences .\n OUTPUT:\n " }, { "from": "agent", "value": "inducing angiogenesis;resisting cell death;activating invasion and metastasis" } ]

Ewing sarcoma is a sarcoma with poor prognosis despite current therapies , particularly for patients with advanced-stage disease . Lungs and bone ( marrow ) , organs of predilection for ( primary/metastatic ) Ewing sarcoma , represent predominant CXCL12 sources . METHODS : To gain insight into the role of the CXCR4-CXCL12 axis in Ewing sarcoma , CXCR4 , CXCL12 and hypoxia-inducible factor-1alpha protein expression was studied in therapy-naive and metastatic tumors by immunohistochemistry . CXCR4 function was assessed in vitro , by flow cytometry and proliferation/ cell viability assays , in the presence of recombinant CXCL12 and/or CXCR4-antagonist AMD3100 or under hypoxic conditions . RESULTS : Whereas CXCR4 was predominantly expressed by tumor cells , CXCL12 was observed in both tumor and stromal areas . Survival analysis revealed an ( expression level-dependent ) negative impact of CXCR4 expression ( p &lt ; 0.04 ) . A role for the CXCR4-CXCL12 axis in Ewing sarcoma growth was suggested by our observations that i ) CXCR4 expression correlated positively with tumor volume at diagnosis ( p = 0.013 ) , ii ) CXCL12 was present within the microenvironment of virtually all cases , iii ) CXCL12 induced proliferation of CXCR4-positive Ewing sarcoma cell lines , which could be abrogated by AMD3100 . CXCR4 expression was not correlated with occurrence of metastatic disease . Also , therapy-naive tumors demonstrated higher CXCR4 expression as compared to metastases ( p = 0.027 ) . Evaluation of in vivo hypoxia-inducible factor-1alpha expression and culture of cells under hypoxic conditions revealed no role for hypoxia in CXCR4 expression . CONCLUSIONS : Together , our results imply a crucial role for the CXCR4-CXCL12 axis in auto- and/or paracrine growth stimulation . Integration of CXCR4-targeting strategies into first- and/or second-line treatment regimens may represent a promising treatment option for Ewing sarcoma .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

Our recent research has implied that BMP-6 may suppress breast cancer metastasis . In the present study , we extended to elucidate the molecular mechanism by which BMP-6 exerts its anti-tumorigenic effect . METHODS The Boyden chamber assay was used to examine the ability of BMP-6 and HO-1 in MCF-7 malignant progress . RT-PCR , western blot , luciferase assay , and quantitative CHIP were used to determine the potential mechanism and signaling pathways by which BMP-6 and HO-1 function as anti-metastatic factors in MCF-7 cells . RESULTS The Boyden chamber assay showed that BMP-6 inhibited the migration and invasion of MCF-7 cells , which effect was significantly deprived by knockdown of HO-1 . We further demonstrated that BMP-6 treatment resulted in an activation of HO-1 transcription through the recruitment of Smad1/5 to the Smad-responsive element on its promoter . In addition , BMP-6-induced up-regulation of HO-1 exhibited an inhibitory effect on MMP-9 secretion in a paracrine action in MCF-7 cells . Overexpression of BMP-6 and HO-1 synergistically suppressed MMP-9 transcription , which effect was specifically mediated via the MAPK/p38/AP-1 signaling . However , blockade of HO-1 using ZnPPIX totally abolished BMP-6-regulated MMP-9 activation in MCF-7 cells . CONCLUSIONS These observations suggest a novel role of BMP-6/HO-1 cascade to relieve breast cancer metastasis by regulating the secretion of growth factors in tumor microenvironment .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;sustaining proliferative signaling" } ]

Recent in vitro studies suggested that ERβ may suppress tumor growth . No research was reported whether ERβ can be used as therapeutic agent for colon cancer . METHODS In this study , ERβ gene constructed into adenoviral ( Ad ) vectors was used to treat colon cancer HCT-116 cells alone or in combination with raloxifene . In vitro and in vivo studies were conducted to investigate the therapeutic effects of ERβ and raloxifene in HCT-116 cells . RESULTS Our results indicated that , although Ad-ERβ alone had no effect on the proliferation of HCT-116 cells , the combination of Ad-ERβ with raloxifene significantly inhibited the proliferation of HCT-116 cells . The apparently apoptotic induction effects may partly explain the cytotoxicity of the two agents . The results of the study of ERβ on migration and invasion of HCT-116 cells demonstrated that overexpression of ERβ significantly decreased cell migration and increased invasion of cells . The antitumor efficacies of ERβ as well as raloxifene were further investigated on HCT-116 tumor bearing mice . Results demonstrated that both Ad-ERβ and raloxifene individually inhibited tumor growth . The combination group showed the highest inhibitory efficiency compared with other three groups .

Although erlotinib did not have any effect on the proliferation of SBC-5 cells in vitro , it significantly suppressed bone and lung metastases in vivo , but not liver metastases .

Here , we report that mutant p53 exerts oncogenic functions and promotes EMT in endometrial cancer ( EC ) by directly binding to the promoter of miR-130b ( a negative regulator of ZEB1 ) and inhibiting its transcription . We transduced p53 mutants into p53-null EC cells , profiled the miRNA expression by miRNA microarray and identified miR-130b as a potential target of mutant p53 . Ectopic expression of p53 mutants repressed the expression of miR-130b and triggered ZEB1-dependent EMT and cancer cell invasion . Loss of an endogenous p53 mutation increased the expression of miR-130b , which resulted in reduced ZEB1 expression and attenuation of the EMT phenotype . Furthermore , re-expression of miR-130b suppressed mutant p53-induced EMT and ZEB1 expression . Importantly , the expression of miR-130 was significantly reduced in EC tissues , and patients with higher expression levels of miR-130b survived longer .

The histone methyltransferase MMSET/WHSC1 ( Multiple Myeloma SET domain ) is overexpressed in a number of metastatic tumors , but its mechanism of action has not been defined . In this work , we found that PCa cell lines expressed significantly higher levels of MMSET compared with immortalized , non-transformed prostate cells . Knockdown experiments showed that , in metastatic PCa cell lines , dimethylation of lysine 36 and trimethylation of lysine 27 on histone H3 ( H3K36me2 and H3K27me3 , respectively ) depended on MMSET expression , whereas depletion of MMSET in benign prostatic cells did not affect chromatin modifications . Knockdown of MMSET in DU145 and PC-3 tumor cells decreased cell proliferation , colony formation in soft agar and strikingly diminished cell migration and invasion . Conversely , overexpression of MMSET in immortalized , non-transformed RWPE-1 cells promoted cell migration and invasion , accompanied by an epithelial-mesenchymal transition ( EMT ) . Among a panel of EMT-promoting genes analyzed , TWIST1 expression was strongly activated in response to MMSET . Chromatin immunoprecipitation analysis demonstrated that MMSET binds to the TWIST1 locus and leads to an increase in H3K36me2 , suggesting a direct role of MMSET in the regulation of this gene . Depletion of TWIST1 in MMSET-overexpressing RWPE-1 cells blocked cell invasion and EMT , indicating that TWIST1 was a critical target of MMSET , responsible for the acquisition of an invasive phenotype .

Methylation of the PCDH8 gene promoter was observed in 100% ( 4/4 ) of cell lines and 55.38% ( 36/65 ) of the primary gastric cancer by methylation-specific PCR , but not in normal gastric mucosa ( 0/10 ) . Methylated PCDH8 was significantly associated with lymph node metastasis in a logistic regression analysis . The demethylation reagent 5-aza-2'-deoxycytidine was able to restore or upregulate PCDH8 expression in gastric cancer cell lines . Ectopic expression of PCDH8 in silenced gastric cancer cells significantly inhibited cell migration and induced apoptosis . For the first time , our study demonstrates the epigenetic inactivation of PCDH8 by promoter methylation and its tumor suppressor function in human gastric cancer . Thus , PCDH8 could be identified as a candidate tumor suppressor in human gastric cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;resisting cell death" } ]

Metformin , a widely used antidiabetic agent , exerts antitumoral and antiproliferative action . In this study , the addition of metformin to 2-deoxyglucose ( 2DG ) inhibited mitochondrial respiration and glycolysis in prostate cancer cells leading to a severe depletion in ATP . The combination of the two drugs was much more harmful for cancer cells than the treatment with metformin or 2DG alone , leading to 96% inhibition of cell viability in LNCaP prostate cancer cells . In contrast , a moderate effect on cell viability was observed in normal prostate epithelial cells . At the cellular level , the combination of metformin and 2DG induced p53-dependent apoptosis via the energy sensor pathway AMP kinase , and the reexpression of a functional p53 in p53-deficient prostate cancer cells restored caspase-3 activity . In addition to apoptosis , the combination of metformin and 2DG arrested prostate cancer cells in G(2)-M . This G(2)-M arrest was independent of p53 and correlated with a stronger decrease in cell viability than obtained with either drug . Finally , metformin inhibited 2DG-induced autophagy , decreased beclin 1 expression , and triggered a switch from a survival process to cell death . Our study reinforces the growing interest of metabolic perturbators in cancer therapy and highlights the potential use of the combination of metformin and 2DG as an anticancerous treatment .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;resisting cell death" } ]

Glioblastoma multiforme is the most aggressive type of primary brain tumors in humans . In this study , we introduce oxidative stress-energy depletion ( OSED ) therapy as a new suggested treatment for glioblastoma . OSED utilizes D-amino acid oxidase ( DAO ) , which is a promising therapeutic protein that induces oxidative stress and apoptosis through generating hydrogen peroxide ( H2O2 ) . OSED combines DAO with 3-bromopyruvate ( 3BP ) , a hexokinase II ( HK II ) inhibitor that interferes with Warburg effect , a metabolic alteration of most tumor cells that is characterized by enhanced aerobic glycolysis . Our data revealed that 3BP induced depletion of energetic capabilities of glioma cells. 3BP induced H2O2 production as a novel mechanism of its action . C6 glioma transfected with DAO and treated with D-serine together with 3BP-sensitized glioma cells to 3BP and decreased markedly proliferation , clonogenic power and viability in a three-dimensional tumor model with lesser effect on normal astrocytes . DAO gene therapy using atelocollagen as an in vivo transfection agent proved effective in a glioma tumor model in Sprague-Dawley ( SD ) rats , especially after combination with 3BP .

METHODS AND RESULTS 13 clinical pathological factors in 255 patients with stage Ib to IIb cervical cancer undergoing radical hysterectomy and systematic lymphadenectomy were analyzed to screen for factors related to prognosis . The cumulative 5-year survival of the 255 patients was 75.7% . The result of the univariate analysis suggested that clinical stage , cell differentiation , depth of cervical stromal invasion , parametrial tissue involvement , and lymph node metastasis were prognostic factors for patients with stage Ib to IIb cervical cancer ( P<0.05 ) . Compared with cases with involvement of iliac nodes , obturator nodes , or inguinal lymph nodes , cases with metastasis to the common iliac lymph nodes had a poorer prognosis ( P<0.05 ) . Cases with involvement of four or more lymph nodes had a poorer prognosis than those with involvement of three or fewer lymph nodes ( P<0.05 ) . Using multivariate Cox proportional hazards model regression analysis , non-squamous histological type , poor differentiation , parametrial tissue involvement , and outer 1/3 stromal invasion were found to be independently related to patients poor prognosis ( P<0.05 ) . CONCLUSION Non-squamous histological type , poor cell differentiation , parametrial tissue involvement , and outer 1/3 stromal invasion are the independent poor prognostic factors for patients with stage Ib to IIb cervical cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

The reason that cancer cells have a higher rate of aerobic glycolysis , but not oxidative phosphorylation , remains largely unclear . Herein , we proposed an epigenetic mechanism of the Warburg effect . Fructose-1,6-bisphosphatase-1 ( FBP1 ) , which functions to antagonize glycolysis was downregulated through NF-kappaB pathway in Ras-transformed NIH3T3 cells . Restoration of FBP1 expression suppressed anchorage-independent growth , indicating the relevance of FBP1 downregulation in carcinogenesis . Indeed , FBP1 was downregulated in gastric carcinomas ( P<0.01 , n=22 ) and gastric cancer cell lines ( 57% , 4/7 ) . Restoration of FBP1 expression reduced growth and glycolysis in gastric cancer cells . Moreover , FBP1 downregulation was reversed by pharmacological demethylation . Its promoter was hypermethylated in gastric cancer cell lines ( 57% , 4/7 ) and gastric carcinomas ( 33% , 33/101 ) . Inhibition of NF-kappaB restored FBP1 expression , partially through demethylation of FBP1 promoter . Notably , Cox regression analysis revealed FBP1 promoter methylation as an independent prognosis predicator for gastric cancer ( hazard ratio : 3.60 , P=0.010 ) . In summary , we found that NF-kappaB functions downstream of Ras to promote epigenetic downregulation of FBP1 . Promoter methylation of FBP1 can be used as a new biomarker for prognosis prediction of gastric cancer . Such an important epigenetic link between glycolysis and carcinogenesis partly explains the Warburg effect .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

We have shown that oral tolerance induces antigen-specific immune suppression of HBsAg by feeding hepatitis B virus ( HBV ) antigens . In the present study we evaluated the effect of oral tolerance induction toward HBV or HCC antigens on the growth of experimental HCC-expressing HBsAg in mice . Tolerance induction was induced in mice by 5 oral feedings of 1 microg HBV antigens or HCC-extracted proteins ( 50 microg protein ) before vaccination with recombinant HBsAg . Splenocytes ( 2 x 10(6) ) from these mice were transferred to sublethally irradiated athymic BALB/c mice previously transplanted subcutaneously with 10(7) human hepatoma Hep3B cells . Adoptive transfer of splenocytes immunized toward HBsAg prevented tumor growth . At 4 weeks after splenocyte transplantation , tumor volume and serum alpha-fetoprotein ( AFP ) levels in athymic mice transplanted with splenocytes immunized to HBsAg were undetectable as compared with 1,048 +/- 738 mm(3) and 2,500 +/- 1,431 ng/ml in recipients of na�ve splenocytes ( p &lt ; 0.0001 ) . Mice receiving splenocytes tolerized toward Hep3B cells , as manifested by reduced serum HBs antibody levels , reduced HBV-specific stimulation index and reduced HBV-specific-IFN gamma spot-forming cells , had early tumor growth evident by elevated AFP serum levels , weight loss and mortality , which were suppressed at 6 weeks . Mice transplanted with splenocytes tolerized toward HBV antigens did not have direct evidence of tumor growth . Induction of oral tolerance toward HCC-extracted proteins enabled transient tumor growth in this model . This effect was mediated through downregulation of the anti-HBV immune response .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

Here we report that Cdk4-null mouse embryonic fibroblasts are resistant to transformation in response to Ras activation with dominant-negative ( DN ) p53 expression or in the Ink4a/Arf-null background , judged by foci formation , anchorage-independent growth , and tumorigenesis in athymic mice . Cdk4-null fibroblasts proliferate at normal rates during early passages . Whereas Cdk4(+/+)Ink4a/Arf(-/-) cells are immortal in culture , Cdk4(-/-)Ink4a/Arf(-/-) cells undergo senescence during continuous culture , as do wild-type cells . Activated Ras also induces premature senescence in Cdk4(-/-)Ink4a/Arf(-/-) cells and Cdk4(-/-) cells with DNp53 expression . Thus , Cdk4 deficiency causes senescence in a unique Arf/p53-independent manner , which accounts for the loss of transformation potential . Cdk4-null cells express high levels of p21(Cip1/Waf1) with increased protein stability . Suppression of p21(Cip1/Waf1) by small interfering RNA ( siRNA ) , as well as expression of HPV-E7 oncoprotein , restores immortalization and Ras-mediated transformation in Cdk4(-/-)Ink4a/Arf(-/-) cells and Cdk4(-/-) cells with DNp53 expression . Therefore , Cdk4 is essential for immortalization , and suppression of Cdk4 could be a prospective strategy to recruit cells with inactive Arf/p53 pathway to senescence .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

The cancer cells ' glycolytic phenotype , first reported by Otto Warburg , is necessary for the optimal routing of somatic cells to pluripotency . However , how iPS cells establish a Warburg-like metabolic phenotype and whether the metabolic pathways that support the bioenergetics of iPS cells are produced by the same mechanisms that are selected during the tumorigenic process remain largely unexplored . We recently investigated whether the reprogramming-competent metabotype of iPS cells involves changes in the activation/expression status of the H ( + ) -ATPase , which is a core component of mitochondrial oxidative phosphorylation that is repressed at both the activity and protein levels in human carcinomas , and of the lipogenic switch , which refers to a marked overexpression and hyperactivity of the acetyl-CoA carboxylase ( ACACA ) and fatty acid synthase ( FASN ) lipogenic enzymes that has been observed in nearly all examined cancer types . A comparison of a starting population of mouse embryonic fibroblasts and their iPS cell progeny revealed that somatic cell reprogramming involves a significant increase in the expression of ATPase inhibitor factor 1 ( IF1 ) , accompanied by extremely low expression levels of the catalytic β-F1-ATPase subunit . The pharmacological inhibition of ACACA and FASN activities markedly decreases reprogramming efficiency , and ACACA and FASN expression are notably upregulated in iPS cells . Importantly , iPS cells exhibited a significant intracellular accumulation of neutral lipid bodies ; however , these bodies may be a reflection of intense lysosomal/autophagocytic activity rather than bona fide lipid droplet formation in iPS cells , as they were largely unresponsive to pharmacological modulation of PPARgamma and FASN activities . The AMPK agonist metformin , which endows somatic cells with a bioenergetic infrastructure that is protected against reprogramming , was found to drastically elongate fibroblast mitochondria , fully reverse the high IF1/β-F1-ATPase ratio and downregulate the ACACA/FASN lipogenic enzymes in iPS cells . The mitochondrial H ( + ) -ATP synthase and the ACACA/FASN-driven lipogenic switch are newly characterized as instrumental metabolic events that , by coupling the Warburg effect to anabolic metabolism , enable de-differentiation during the reprogramming of somatic cells to iPS cells .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

S100A11 ( calgizzarin ) , a member of the S100 Ca(2+)-binding protein family , is involved in several different biological processes . S100A11 has been found up-regulated in PTC , both at the mRNA and protein levels . OBJECTIVE Through a combination of expression analysis and functional in vitro and in vivo studies , we have attempted to gain insight into the relevance of S100A11 overexpression in PTC biology . DESIGN The expression of the S100A11 gene in PTC was investigated in several gene expression data sets . The effect of S100A11 silencing on the hallmarks of the malignant phenotype of several PTC-derived cell lines was investigated . In NIH3T3 cells , the cooperation of S100A11 with the different PTC-specific oncogenes was assessed . RESULTS We found that the S100A11 gene expression is frequently up-regulated in PTC , anaplastic thyroid carcinoma , but not in follicular thyroid carcinoma . S100A11 overexpression was also detected in PTC-derived cell lines , which were then used for functional studies . S100A11 silencing in PTC-derived cell lines did not affect cell proliferation , whereas it reduced the loss of contact inhibition , anchorage-independent growth , and resistance to anoikis . Cotransfection experiments in NIH3T3 cells showed that overexpression of the S100A11 gene was able to enhance the transforming capabilities of the different PTC-associated oncogenes by affecting the loss of contact inhibition , anchorage-independent growth , and in vivo tumor formation .

We determined the effects of S-nitrosoglutathione ( GSNO , NO-donor ) and U0126 ( MEK inhibitor ) on insulin-like growth factor-I ( IGF-I ) and epidermal growth factor ( EGF ) signaling , proliferation and invasion in cancer cell lines . GSNO inhibits phosphorylation of IGF-I receptor ( IGF-IR ) , EGF receptor ( EGFR ) and Akt , but upregulates ERK1/2 phosphorylation in MIAPaCa-2 and HCT-116 cells after stimulation by IGF-I and EGF . On the other hand , U0126 inhibits phosphorylation of ERK1/2 , but upregulates phosphorylation of IGF-IR and EGFR in MIAPaCa-2 and HCT-116 cells .

Rats were exposed to crystalline silica by inhalation ( 15 mg m(-3) , 6 h per day , 5 days ) and global gene expression profile was determined in the lungs by microarray analysis at 1 , 2 , 4 , 8 and 16 weeks following termination of silica exposure . The number of significantly differentially expressed genes ( >1.5-fold change and <0.01 false discovery rate P-value ) detected in the lungs during the post-exposure time intervals analyzed exhibited a steady increase in parallel with the progression of silica-induced pulmonary toxicity noticed in the rats . Quantitative real-time PCR analysis of a representative set of 10 genes confirmed the microarray findings . The number of biological functions , canonical pathways and molecular networks significantly affected by silica exposure , as identified by the bioinformatics analysis of the significantly differentially expressed genes detected during the post-exposure time intervals , also exhibited a steady increase similar to the silica-induced pulmonary toxicity . Genes involved in oxidative stress , inflammation , respiratory diseases , cancer , and tissue remodeling and fibrosis were significantly differentially expressed in the rat lungs ; however , unresolved inflammation was the single most significant biological response to pulmonary exposure to silica . Excessive mucus production , as implicated by significant overexpression of the pendrin coding gene , SLC26A4 , was identified as a potential novel mechanism for silica-induced pulmonary toxicity . Collectively , the findings of our study provided insights into the molecular mechanisms underlying the progression of crystalline silica-induced pulmonary toxicity in the rat . Published 2012 .

Health benefits have been linked to additive and synergistic combinations of phytochemicals in fruits and vegetables . Nigella sativa has been shown to possess anti-carcinogenic activity , inhibiting growth of several cancer cell lines in vitro . However , the molecular mechanisms of the anti-cancer properties of Nigella sativa phytochemical extracts have not been completely understood . Our data showed that Nigella sativa extracts significantly inhibited human breast cancer MDA-MB-231 cell proliferation at doses of 2.5-5 μg/mL ( P<0.05 ) . Apoptotic induction in MDA-MB-231 cells was observed in a dose-dependent manner after exposure to Nigella sativa extracts for 48 h .

Major risk factors of HCC include infection with hepatitis B or C viruses , alcohol and non-alcoholic fatty liver disease . HCC is difficult to diagnose at early stage , and has a very poor survival rate when diagnosed at a late stage . The majority of HCC-related deaths result from local invasion ( to cause liver failure ) or distant metastases . There is an urgent need to identify effective molecular targets for the treatment of the disease . As the target of an established class of therapeutic agent thiazolidinediones ( TZDs ) , peroxisome-proliferator-activated receptor γ ( PPARγ ) has been widely studied for its role in the development of HCC . A substantial body of evidence based on in vitro and in vivo models indicates that the activation of PPARγ is able to inhibit HCC cell proliferation and tumor growth through inducing cell cycle arrest and apoptosis via the regulation of a panel of downstream effector molecules . PPARγ activation also induces an inhibitory effect on HCC metastasis . Meanwhile , there is new evidence suggesting that PPARγ inhibition could also be anti-tumorigenic . In the present review , we summarize the available information on the role of PPARγ in HCC development and spread , and discuss whether PPARγ activation by TZDs could play a role in the treatment of HCC , summarizing both in vitro and in vivo . Considering the available data , PPARγ seems to exert beneficial effects against HCC and may therefore represent as a therapeutic target .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling;activating invasion and metastasis" } ]

However , its precise role in the tumorigenesis of Nasopharyngeal Carcinoma ( NPC ) remains to be elucidated . EZH2 was depleted by retroviral infection in the NPC cells ( HK-1 , CNE-2 , CNE-1 and C666-1 ) . The degree of EZH2 knockdown was then assessed by real-time quantitative PCR and Western Blot analysis . Cell proliferation was assessed using the soluble tetrazolium salt ( MTS ) cell proliferation assay , and cell cycle was measured by FACS test . The methylation status of p16(INK4a )was determined by bisulphate treatment of the DNA , followed by MSP . EZH2 was over-expressed in NPC cells , and the expression in undifferentiated-derived NPC cells ( CNE-1 , C666-1 ) was more significant than differentiated-derived NPC cells ( HK-1 , CNE-2 ) . EZH2 was successfully depleted after retroviral infection in C666-1 cells , and the EZH2 depletion could inhibit the proliferation and arrested G1/S phase of NPC cells . In addition , both mRNA and protein levels of p16(INK4a) increased significantly in presence of EZH2 depletion . The further Methylation-Specific Polymerase Chain Reaction ( MSP ) assay suggested that over-expressed EZH2 may contribute to the reduction of p16(INK4a) expression by hyper methylating its promoter . EZH2 is overexpressed in NPC and reduces expression of p16(INK4a) by influencing methylation , opening therapeutic options .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

We found that a novel combination of vanadium-based PTP inhibitors with RA induced extensive differentiation in neuroblastoma cells . In contrast to RA alone , this led to either permanent differentiation or senescence after 14days of combined treatment followed by chemical removal . Senescence was dependent in part on synergistic AKT and ERK activation. p21 was also strongly induced , but in contrast to oncogene-induced senescence , p53 was not activated . Vanadium-based inhibitors thus serve strongly to enhance RA's ability to drive differentiation and a novel form of senescence in neuroblastoma cells .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality" } ]

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" } ]

The molecular events in arsenic-induced carcinogenicity remain to be defined . In the NuLi-1 immortalized human lung epithelial cell line with p53 and pRb deficiency , exposure to low doses of arsenic trioxide for 72 h promoted cell proliferation and upregulated the gene transcription levels of FOXM1 , CDC6 , CDC25A , and cyclin D1 , which are both critical cell cycle regulatory genes and proto-oncogenes . Continuous in vitro exposure to 1 �M arsenic trioxide for 34 wks induced malignant cell transformation , as evidenced by enhanced anchorage-independent cell growth . The expression of FOXM1 , CDC6 , CDC25A , and Cyclin D1 was dynamically elevated at the gene transcription and protein levels in the process of cell transformation . The carcinogenic ability of transformed cell colonies coincides with the expression levels of FOXM1 in in vitro anchorage-independent growth assays and in vivo tumor xenograft formation assays . In reverse , the knockdown of FOXM1 in lung adenocarcinoma A549 cells or arsenic-transformed NuLi-1 cells significantly decreased anchorage-independent cell growth and tumor xenograft formation . The transformed NuLi-1 cells showed genomic instability in the form of copy number variation ( CNV ) at chromosome 1 , 5 , 6 , 18 , and 20 , but not loss of heterozygosity ( LOH ) . These results showed for the first time that chronic exposure to low doses of arsenic trioxide promoted lung carcinogenicity , in part by aberrantly upregulating FOXM1 and its associated oncogenes , when the tumor suppressor genes p53 and pRb were inactivated. � 2012 Wiley Periodicals , Inc .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

Advanced disease is characterized by an increased incidence of BCR-ABL1 mutations . 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" } ]

Both clinics have sound experience of RCC surgery , and modern laparoscopic equipment . A retrospective chart review of all patients with RCC diagnosed and treated in the last year was conducted at the two sites . MATERIALS AND METHODS In total , 88 patients ( 66 males and 22 females , mean age 58 years , range 24-81 years ) were enrolled in the study . Comparisons were made between some clinical and pathologic parameters with an established prognostic and therapeutic impact . The type of surgery perormed at both sites was analyzed as well . All these comparative studies were performed in relation to the 2008 EAU guidelines on the current management of RCC . Commercially available statistical software was used for the purpose . RESULTS The results showed no difference between the two sites regarding the RCC incidence and the patients ' age and gender . Significant differences ( p value &lt ; 0.0001 ) emerged in terms of : the median size of the tumors at surgery ( 8.5 cm in Varna , SD + 4.04 vs. 4.4 cm in Bari , SD _ 2.02 ) ; T-stage of the tumor ( Varna T T2-30% , T3-22% , T4-15% vs. Bari T1-64% , T2-12% , T3-24% , T4-0% ) ; N-positive disese ( 24% vs. 2% ) ; distant metastases ( 20% vs. 2% ) and presence of necrosis in the renal masses ( 37% vs. 19% ) . Thus , 85% of Varna patients underwent open radical nephrectomy , 11% nephron-sparing surgery and 4% explorative laparotomy , due to inoperability of the renal mass . Only 29% of Bari patients were treated by open radical nephrectomy , 12% underwent laparoscopic nephrectomy , 57% open partial nephrectomy and 2% laparoscopic partial tumor resection . Conclusions : These numbers demonstrate more advantageous tumour features at the Italian clinic in terms of organ-sparing surgical options ( open and laparoscopic ) , whereas in the Bulgarian clinic the tumour features pose certain limitations to the application of modern surgical techniques . This difference is due to early diagnosis of RCC in Italy , allowing treatment of smaller volume tumors .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

In this study , we show that the down-regulation of Notch1 and Notch3 in two HCC cell lines resulted in Hes1 down-regulation , CDKN1C/P57 up-regulation , and reduced cell growth . In line with these data , we report that CDKN1C/P57 is a target of transcriptional repression by the Notch effector , Hes1 . We found that the up-regulation of CDKN1C/P57 by cDNA transfection decreased tumor growth , as determined by growth curve , flow cytometry analysis , and cyclin D1 down-regulation , without affecting the apoptosis machinery . Indeed , the expression of Bax , Noxa , PUMA , BNIP(3) , and cleaved caspase-3 was not affected by CDKN1C/P57 induction . Morphologically CDKN1C/p57-induced HCC cells became flat and lengthened in shape , accumulated the senescence-associated β-galactosidase marker , and increased P16 protein expression . Evaluation of senescence in cells depleted both for Hes1 and CDKN1C/P57 revealed that the senescent state really depends on the accumulation of CDKN1C/p57 . Finally , we validated our in vitro results in primary HCCs , showing that Hes1 protein expression inversely correlates with CDKN1C/P57 mRNA levels . In addition , reduced Hes1 protein expression is accompanied by a shorter time to recurrence after curative resection , suggesting that Hes1 may represent a biomarker for prediction of patients with poor prognosis .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;enabling replicative immortality" } ]

It is highly abundant , its expression is strongly regulated in many tumor entities including lung adenocarcinoma and hepatocellular carcinoma as well as physiological processes , and it is associated with many RNA binding proteins and highly conserved throughout evolution . The nuclear transcript MALAT-1 has been functionally associated with gene regulation and alternative splicing and its regulation has been shown to impact proliferation , apoptosis , migration and invasion . Here , we have developed a human and a mouse knockout system to study the loss-of-function phenotypes of this important ncRNA . In human tumor cells , MALAT1 expression was abrogated using Zinc Finger Nucleases . Unexpectedly , the quantitative loss of MALAT1 did neither affect proliferation nor cell cycle progression nor nuclear architecture in human lung or liver cancer cells . Moreover , genetic loss of Malat1 in a knockout mouse model did not give rise to any obvious phenotype or histological abnormalities in Malat1-null compared with wild-type animals .

An important goal of personalized cancer therapy is to tailor specific therapies to the mutational profile of individual patients . However , whole genome sequencing studies have shown that the mutational profiles of cancers evolve over time and often differ between primary and metastatic sites . Activating point mutations in the PIK3CA gene are common in primary breast cancer tumors , but their presence in breast cancer bone metastases has not been assessed previously . Results . Fourteen patients with breast cancer bone metastases were biopsied by three methods : CT-guided bone biopsies ; bone marrow trephine biopsies ; and bone marrow aspiration . Samples that were positive for cancer cells were obtained from six patients . Three of these patients had detectable PIK3CA mutations in bone marrow cancer cells . Primary tumor samples were available for four of the six patients assessed for PIK3CA status in their bone metastases . For each of these , the PIK3CA mutation status was the same in the primary and metastatic sites . Conclusions . PIK3CA mutations occur frequently in breast cancer bone metastases . The PIK3CA mutation status in bone metastases samples appears to reflect the PIK3CA mutation status in the primary tumour .

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" } ]

To explore the role of pan-HER inhibitor in breast cancer , we investigated the antitumor effect and mechanisms of HM781-36B in breast cancer cell lines . Six breast cancer cell lines ( BT474 , MDA-MB-453 , SK-BR-3 , T47D , MCF-7 , and MDA-MB-231 ) were tested . The growth inhibitory effect was assessed using the tetrazolium bromide [ 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl-tetrazolium bromide ] assay . The cell cycle at various concentrations of HM781-36B was analyzed by flow cytometry , and analysis of downstream molecules was performed by western blot analysis . Interaction of HM781-36B with cytotoxic chemotherapeutic agents was analyzed by combination index using CalcuSyn . The HER2-amplified cells ( SK-BR-3 , BT474 , and MDA-MB-453 ) were sensitive to HM781-36B ( IC50=0.001 μmol/l , 0.0012 μmol/l , and 0.0095 μmol/l , respectively ) . HM781-36B induced G1 arrest and resulted in apoptosis . It reduced the level of p-HER2 , p-AKT , p-ERK , and p-STAT3 . HM781-36B combined with 5-fluorouracil , cisplatin , paclitaxel , or gemcitabine showed a synergistic inhibitory effect on the HER2-amplified and on some of the HER2-nonamplified breast cancer cells .

NEDD8 ( neural precursor cell-expressed developmentally down-regulated ) is an ubiquitin-like protein essential for protein processing and cell cycle progression . We recently demonstrated that ubiquitin-activating enzyme ( Uba)3 , the catalytic subunit of the NEDD8-activating enzyme , inhibits ERalpha transcriptional activity . Here we report that Uba3-mediated inhibition of ERalpha transactivation function is due to increased receptor protein turnover . Coexpression of Uba3 with ERalpha increased receptor degradation by the 26S proteasome . Inhibition of NEDD8 activation and conjugation diminished polyubiquitination of ERalpha and blocked proteasome-mediated degradation of receptor protein . The antiestrogen ICI 182,780 is known to induce ER degradation . In human MCF7 breast cancer cells modified to contain a disrupted NEDD8 pathway , ICI 182,780 degradation of ERalpha was impaired , and the antiestrogen was ineffective at inhibiting cell proliferation . This study provides the first evidence linking nuclear receptor degradation with the NEDD8 pathway and the ubiquitin-proteasome system , suggesting that the two pathways can act together to modulate ERalpha turnover and cellular responses to estrogens . Based on our observation that an intact NEDD8 pathway is essential for the antiproliferation activity of the ICI 182,780 in ERalpha positive breast cancer cells , we propose that disruptions in the NEDD8 pathway provide a mechanism by which breast cancer cells acquire antiestrogen resistance while retaining expression of ERalpha .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

However , the mechanisms of regulating PKM2 are not fully elucidated . Here , we identified the protein-serine/threonine kinase PIM2 , a known oncogene , as a novel binding partner of PKM2 . The interaction between PIM2 and PKM2 was confirmed by multiple biochemical approaches in vitro and in cultured cells . Importantly , we found that PIM2 could directly phosphorylate PKM2 on the Thr-454 residue , resulting in an increase of PKM2 protein levels . Compared with wild type , PKM2 with the phosphorylation-defective mutation displayed a reduced effect on glycolysis , co-activating HIF-1α and β-catenin , and cell proliferation , while enhancing mitochondrial respiration of cancer cells . These findings demonstrate that PIM2-dependent phosphorylation of PKM2 is critical for regulating the Warburg effect in cancer , highlighting PIM2 as a potential therapeutic target .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics;genomic instability and mutation" } ]

We report the clinicopathologic features and flow cytometric findings for 11 cases of MZMT . At the time of discovery of metastatic disease , the patients , six women and five men , ranged in age from 20 to 83 years . Primary sites of involvement included the parotid gland ( eight cases ) , submandibular gland ( two cases ) , and the nasal septum ( one case ) . With one exception , all the patients had at least a single recurrences of their primary mixed tumor , but two or more recurrences were the norm before development of metastatic foci . The metastases were discovered from six to 52 years following the occurrence of the primary tumor . Metastatic deposits were identified in bone , lung , regional lymph nodes , skin , kidney , retroperitoneum , oral cavity , pharynx , calvarium , and central nervous system . The metastases either occurred simultaneously with an episode of recurrent mixed tumor ( n = 5 ) or from 5 to 29 years after a recurrence ( n = 6 ) . The treatment of the primary , recurrent , and metastatic neoplasms was surgical excision . Follow-up , ranging from 8 months to 16 years following the diagnosis of MZMT , revealed seven patients to be alive without disease ( 64% ) and two dead of causes unrelated to metastatic disease ( 18% ) . Two patients ( 18% ) died as a direct result of metastatic tumor at 3 and 2 years after metastasis of their mixed tumors . Flow cytometric analysis revealed a diploid DNA cell population in the primary and/or metastatic tumors in nine cases . Aneuploid DNA cell content was identified in two of the cases . DNA ploidy levels and cell proliferation rates were compared with those of conventional benign mixed tumors and also with malignant mixed tumors . Retrospective analysis of histologic parameters ( mitotic rate , cellular pleomorphism , infiltrative growth , vascular or lymphatic invasion ) and flow cytometric analysis failed to identify criteria to predict the development of metastasis in these neoplasms .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis;genomic instability and mutation" } ]

In this study the impact of INH treatment on the immune response after repeated intravesical BCG administration was investigated in guinea pigs . INH was given on the 3 days around each BCG instillation . We found that the administration of INH severely impaired the immunological effects of BCG . The induction of mononuclear cell infiltration in the bladder wall was reduced . Enlargement of the regional lymph nodes ( weight and number of cells ) , and increase of MHC Class II expression on the lymph node cells , normally observed after intravesical BCG administration , were inhibited by INH . Systemic immunity , measured by the DTH reaction in the skin to PPD , was also diminished due to the combined treatment of BCG with INH . When INH was administered during the last 4 of 6 BCG instillations , the immune response to BCG was still impaired . A five-fold increase of the dose of BCG did not overcome the effect of INH . INH probably did not exert a direct suppression of the immune system of the guinea pig as the DNCB skin reactivity was not influenced . Although INH concentrations in the urine were high at the onset of the instillation , in vitro experiments indicated that the effect of INH may not be caused by killing of the BCG organisms shortly after application in the bladder . In conclusion , our data in guinea pigs suggest that the use of INH may impair the immune response to intravesical BCG . As this response may be important for the antitumor effect of BCG , urologists should be cautious with the prophylactic use of INH . The influence on the antitumor efficacy is now investigated in man .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

This cyclical requirement for cell division , when not interrupted by the long anovulatory rest periods that occur during pregnancy and lactation , may contribute to the development of ovarian cancer . PURPOSE AND METHODS To test this hypothesis , we isolated rat ovarian surface epithelial cells from 10 adult female Fisher rats , initiated two mixed-population and seven clonal cell lines , and repeatedly subcultured these cells in vitro for more than 20 passages . We then tested them for the acquisition of the following four features associated with transformation : 1 ) the loss of contact inhibition , 2 ) the capacity for substrate-independent growth , 3 ) the ability to form tumors when injected subcutaneously and/or intraperitoneally into athymic mice , and 4 ) cytogenetic abnormalities . RESULTS Loss of contact inhibition was observed in all nine late-passage cell lines . Six of the nine late-passage , but none of the early-passage , cell lines tested exhibited a capacity for substrate-independent growth that was augmented in a dose-dependent manner by epidermal growth factor . Two late-passage cell lines ( clone 2 and mixed-population 2 ) generated tumors in athymic BALB/c mice within 3 weeks following subcutaneous injection of 5 x 10(6) cells , whereas similar numbers of early-passage cells from the same cell lines failed to generate palpable tumors . Late-passage clone 7 cells were tumorigenic when 5 x 10(7) cells were injected intraperitoneally . Two of the cell lines analyzed exhibited alterations involving losses of part or all of one member of the chromosome 5 pair . Clone 2 possessed an interstitial deletion , del(5)(q21.3q24) , consistent with the loss of an uncloned putative tumor suppressor gene at 5q22q23 previously reported to reside near the loci for the interferon alpha , interferon beta , and c-jun genes . Early-passage clone 7 cells exhibited chromosome 5 monosomy , while late-passage cells contained one normal chromosome 5 and a derivative ( 5q12q ) . Southern analysis of the three cell lines revealed no consistent loss of loci for the interferon and c-jun genes , although early-passage clone 7 cells had one half the gene copy number for the interferon beta and c-jun genes and both early- and late-passage clone 7 cells lacked DNA sequences hybridizing with the probe for interferon alpha . CONCLUSION This pattern of passage-dependent spontaneous transformation of rat ovarian surface epithelial cells in vitro supports the hypothesis that repetitious ovulation contributes to the etiology of human ovarian cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

Current management of myeloma bone disease is limited to the use of antiresorptive agents such as bisphosphonates . METHODOLOGY/PRINCIPAL FINDINGS We tested the effects of daily administered parathyroid hormone ( PTH ) on bone disease and myeloma growth , and we investigated molecular mechanisms by analyzing gene expression profiles of unique myeloma cell lines and primary myeloma cells engrafted in SCID-rab and SCID-hu mouse models . PTH resulted in increased bone mineral density of myelomatous bones and reduced tumor burden , which reflected the dependence of primary myeloma cells on the bone marrow microenvironment . Treatment with PTH also increased bone mineral density of uninvolved murine bones in myelomatous hosts and bone mineral density of implanted human bones in nonmyelomatous hosts . In myelomatous bone , PTH markedly increased the number of osteoblasts and bone-formation parameters , and the number of osteoclasts was unaffected or moderately reduced . Pretreatment with PTH before injecting myeloma cells increased bone mineral density of the implanted bone and delayed tumor progression . Human global gene expression profiling of myelomatous bones from SCID-hu mice treated with PTH or saline revealed activation of multiple distinct pathways involved in bone formation and coupling ; involvement of Wnt signaling was prominent . Treatment with PTH also downregulated markers typically expressed by osteoclasts and myeloma cells , and altered expression of genes that control oxidative stress and inflammation . PTH receptors were not expressed by myeloma cells , and PTH had no effect on myeloma cell growth in vitro . CONCLUSIONS/SIGNIFICANCE We conclude that PTH-induced bone formation in myelomatous bones is mediated by activation of multiple signaling pathways involved in osteoblastogenesis and attenuated bone resorption and myeloma growth ; mechanisms involve increased osteoblast production of anti-myeloma factors and minimized myeloma induction of inflammatory conditions .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

Similar clinical studies in humans are unavailable . Our objective is to study the action of dietary astaxanthin in modulating immune response , oxidative status and inflammation in young healthy adult female human subjects . METHODS Participants ( averaged 21.5 yr ) received 0 , 2 , or 8 mg astaxanthin ( n = 14/diet ) daily for 8 wk in a randomized double-blind , placebo-controlled study . Immune response was assessed on wk 0 , 4 and 8 , and tuberculin test performed on wk 8 . RESULTS Plasma astaxanthin increased ( P &lt ; 0.01 ) dose-dependently after 4 or 8 wk of supplementation . Astaxanthin decreased a DNA damage biomarker after 4 wk but did not affect lipid peroxidation . Plasma C-reactive protein concentration was lower ( P &lt ; 0.05 ) on wk 8 in subjects given 2 mg astaxanthin . Dietary astaxanthin stimulated mitogen-induced lymphoproliferation , increased natural killer cell cytotoxic activity , and increased total T and B cell subpopulations , but did not influence populations of Thelper , Tcytotoxic or natural killer cells . A higher percentage of leukocytes expressed the LFA-1 marker in subjects given 2 mg astaxanthin on wk 8 . Subjects fed 2 mg astaxanthin had a higher tuberculin response than unsupplemented subjects . There was no difference in TNF and IL-2 concentrations , but plasma IFN-gamma and IL-6 increased on wk 8 in subjects given 8 mg astaxanthin . CONCLUSION Therefore , dietary astaxanthin decreases a DNA damage biomarker and acute phase protein , and enhances immune response in young healthy females .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation;tumor promoting inflammation" } ]

Meanwhile , methodological means must be proposed to gather information on tumor metabolism in order to adapt these potential therapies to the bioenergetic specificities of tumors . Studies performed on tumors and cancer cell lines have shown that cancer cells bioenergetics is highly variable . This profile changes with microenvironmental conditions ( eg. substrate availability ) , the oncogenes activated ( and the tumor suppressors inactivated ) and the interaction with the stroma ( i.e. reverse Warburg effect ) . Here , we assessed the power of metabolic footprinting ( MFP ) to unravel the bioenergetics and associated anabolic changes induced by three oncogenes , c-Myc , KLF4 and Oct1 . The MFP approach provides a quantitative analysis of the metabolites secreted and consumed by cancer cells . We used ultra performance liquid chromatography for quantifying the amino acid uptake and secretion . To investigate the potential oncogene-mediated alterations in mitochondrial metabolism , we measured oxygen consumption rate and ATP production as well as the glucose uptake and lactate release . Our findings show that c-Myc deficiency initiates the Warburg effect along with a reduction of mitochondrial respiration . KLF4 deficiency also stimulated glycolysis , albeit without cellular respiration impairment . In contrast , Oct1 deficiency reduced glycolysis and enhanced oxidative phosphorylation efficiency . MFP revealed that c-Myc , KLF4 and Oct1 altered amino acid metabolism with specific patterns . We identified isoleucine , α-aminoadipic acid and GABA ( γ-aminoisobutyric acid ) as biomarkers related . Our findings establish the impact of Oct1 , KLF4 and c-Myc on cancer bioenergetics and evidence a link between oncosecretomics and cellular bioenergetics profile .\n OUTPUT:\n " }, { "from": "agent", "value": "cellular energetics" } ]

However , etiology of prostate cancer is still unknown . Individual risk and incidence of prostate cancer may result from the interaction of genetic susceptibility with exposure to environmental factors such as infectious agents , tobacco , occupational exposure , dietary carcinogens , and/or hormonal imbalances leading to injury of the prostate and to the development of chronic inflammation . About 30% of all human cancers are caused by tobacco smoking and inhaled pollutants . Inflammation is now regarded as an important hallmark of cancer . The present study has been aimed to explore the pro-inflammatory levels in prostate carcinoma patients by examining the serum levels of novel cytokine interleukin-18 ( IL-18 ) expression in tobacco exposed population . A total of 578 ( n = 284 biopsy proven prostate cancer patients , n = 294 controls with and without tobacco exposed population ) were recruited . Serum IL-18 ( Interleukin-18 ) level was done by ELISA . The IL-18 levels between cancer patients and controls within same mode tobacco exposure as tobacco smoking ( overall ) showed significant difference ( P &lt ; 0.0001 ) and further we compared within stratified group , it significantly differ ( P &lt ; 0.0001 ) in bidi and cigarette smoking than control non users . Furthermore , IL-18 levels in tobacco chewers ( overall ) with gutkha and khaini chewers showed significant difference ( P &lt ; 0.01 ) than controls non users . Moreover , the IL-18 levels between cancer patients and controls with in of combined mode chewers smokers and alcohol ( CSA ) , smokers with alcohol showed significant difference ( P &lt ; 0.01 ) than controls . The IL-18 levels also differed significantly ( P &lt ; 0.05 ) with smokers and chewers in higher stages of III and IV , and showed non significant with in lower stages . Tobacco exposure enhance the inflammation in prostate carcinoma patients in stratified group as it have been represented as a risk factors in various cancers , but this study provide further its role that seems to influence inflammation especially in prostate carcinoma .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

Fanconi anemia ( FA ) is an inherited DNA instability disorder that is associated with bone marrow failure and a strong predisposition to cancer . Although FA cells experience constitutive chromosomal breaks , cell cycle arrest at the G2 DNA damage checkpoint , and an excess of cell death , some patients do become clinically stable , and the mechanisms underlying this , other than spontaneous reversion of the disease-causing mutation , are not well understood . Here we have defined a clonal phenotype , termed attenuation , in which FA patients acquire an abrogation of the G2 checkpoint arrest . Attenuated cells expressed lower levels of CHK1 ( also known as CHEK1 ) and p53 . The attenuation could be recapitulated by modulating the ATR/CHK1 pathway , and CHK1 inhibition protected FA cells from cell death . FA patients who expressed the attenuated phenotype had mild bone marrow deficiency and reached adulthood , but several of them eventually developed myelodysplasia or leukemia . Better understanding of attenuation might help predict a patient's clinical course and guide choice of treatment . Our results also highlight the importance of evaluating the cellular DNA damage checkpoint and repair pathways in cancer therapies in general .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;genomic instability and mutation" } ]

Because TGFβ1 is a pleiotropic cytokine involved not only in physiologic processes but also in cancer development , we analyzed in A375 human melanoma cells , the effect of TGFβ1 on monocyte chemoattractant protein-1 ( MCP-1 ) and interleukin-10 ( IL-10 ) expression , two known factors responsible for melanoma progression . TGFβ1 increased the expression of MCP-1 and IL-10 in A375 cells , an effect mediated by the cross-talk between Smad , PI3K ( phosphoinositide 3-kinase)/AKT , and BRAF-MAPK ( mitogen activated protein kinase ) signaling pathways . Supernatants from TGFβ1-treated A375 cells enhanced MCP-1-dependent migration of monocytes , which , in turn , expressed high levels of TGF,β1 , bFGF , and VEGF mRNA . Moreover , these supernatants also inhibited functional properties of dendritic cells through IL-10-dependent mechanisms . When using in vitro , the TGFβ1-blocking peptide P144 , TGFβ1-dependent Smad3 phosphorylation , and expression of MCP-1 and IL-10 were inhibited . In vivo , treatment of A375 tumor-bearing athymic mice with P144 significantly reduced tumor growth , associated with a lower macrophage infiltrate and decreased intratumor MCP-1 and VEGF levels , as well as angiogenesis . Finally , in C57BL/6 mice with B16-OVA melanoma tumors , when administered with immunotherapy , P144 decreased tumor growth and intratumor IL-10 levels , linked to enhanced activation of dendritic cells and natural killer cells , as well as anti-OVA T-cell responses . These results show new effects of TGFβ1 on melanoma cells , which promote tumor progression and immunosuppression , strongly reinforcing the relevance of this cytokine as a molecular target in melanoma .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling;inducing angiogenesis" } ]

The role of autophagy in response to ionizing radiation was investigated in human esophageal squamous carcinoma cells . Cell viability and clonogenic survival assay were used to evaluate the radiosensitivity of autophagy inhibitor ( 3-MA ) on esophageal squamous carcinoma cells . The percentage of apoptotic cells and cell cycle analysis were assessed by flow cytometry ; DAPI staining was used to detect apoptotic cells . The expression of beclin-1 and LC3 was measured using a Western blot . The ultrastructural analysis was under the electron microscope. 6 Gy irradiation induced a massive accumulation of autophagosomes accompanied by strong upregulation of beclin-1 and LC3-II expression in TE-1 cells . Compared with radiation alone , 3-MA combined with radiation significantly decreased cell viability , as well as autophagic ratio , beclin-1 , and LC3-II protein level . Inhibition of autophagy increased radiation-induced apoptosis and the percentage of G2/M-phase cells . Blockade of autophagy with 3-MA enhanced cytotoxicity of radiotherapy in human esophageal squamous carcinoma cells . It suggests that inhibition of autophagy could be used as adjuvant therapy to treat esophageal squamous cell carcinoma .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

Thorough understanding of the downstream cellular signaling of gefitinib will facilitate the discovery of biomarkers for predicting outcomes and monitoring anti-EGFR therapies , and provide information for key targets for therapeutic intervention . In this study , we investigated the role of transducer of erbB2.1 ( TOB1 ) in gefitinib therapy . Using the lung carcinoma cell lines A549 and NCI-H1975 , the results suggested that gefitinib might mediate cell cycle arrest in lung cancer cells at least by targeting TOB1 expression . Gefitinib treatment caused cell cycle arrest predominantly at the G1 phase , which is associated with TOB1 nuclear translocation and its interaction with cyclin D1 . We also showed that knockdown of TOB1 expression by RNAi rescued lung cancer cells from gefitinib-induced cell-proliferative arrest .

The purpose of the present study was to investigate the anti-cancer effects of ouabain and Na(+)/K(+)-ATPase alpha1 small interfering ribonucleic acid ( siRNA ) on HepG2 cell proliferation , apoptosis and cell cycle , and to explore the molecular mechanisms . The expression of Na(+)/K(+)-ATPase alpha1 subunit in human hepatocellular carcinoma ( HCC ) , normal liver tissues and human HCC line ( HepG2 , SMMC-7721 and Bel-7402 ) has been investigated . Using the ouabain and Na(+)/K(+)-ATPase alpha1 subunit siRNA , which target the Na(+)/K(+)-ATPase , we have evaluated the effects of inhibiting Na(+)/K(+)-ATPase alpha1 in human HepG2 cells with respect to cell proliferation , morphology , cell cycle , impact on intracellular Ca2++ , reactive oxygen species ( ROS ) concentration , and correlated gene expression level on messenger ribonucleic acid ( mRNA ) and protein .

Ouabain and Na(+)/K(+)-ATPase alpha1 siRNA could inhibit HepG2 cell proliferation . Ouabain could induce HepG2 cell apoptosis and generate S phase arrest , and siRNA could enhance the anti-cancer effect of ouabain that induced HepG2 cells apoptosis via an intracellular Ca(2+) and ROS increase-mediated , and generated cell cycle S phase arresting by decreasing the CyclinA1/cyclin-dependent kinase 2 ( CDK2)/proliferating cell nuclear antigen ( PCNA ) complex product and increasing the expression of cyclin-dependent kinase inhibitor 1A ( P21(CIP1) ) .

Consistent with this role , p21 is a downstream target of several tumour suppressors and oncogenes , and it is downregulated in the majority of tumours , including breast cancer . Here , we report that protein arginine methyltransferase 6 ( PRMT6 ) , a type I PRMT known to act as a transcriptional cofactor , directly represses the p21 promoter . PRMT6 knock-down ( KD ) results in a p21 derepression in breast cancer cells , which is p53-independent , and leads to cell cycle arrest , cellular senescence and reduced growth in soft agar assays and in severe combined immunodeficiency ( SCID ) mice for all the cancer lines examined . We finally show that bypassing the p21-mediated arrest rescues PRMT6 KD cells from senescence , and it restores their ability to grow on soft agar . We conclude that PRMT6 acts as an oncogene in breast cancer cells , promoting growth and preventing senescence , making it an attractive target for cancer therapy .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;sustaining proliferative signaling" } ]

In this study , we explored in vitro the antitumor effects of sorafenib alone and in combination with gemcitabine in epidermal growth factor receptor-tyrosine kinase inhibitor ( EGFR-TKI)-resistant human lung cancer cell lines and the related molecular mechanisms . The NSCLC cell lines A549 ( mutant KRAS ) , H1666 ( mutant BRAF ) and H1975 ( mutant EGFR-T790M ) were treated with sorafenib and gemcitabine alone and in combination . The cytotoxicity was assessed by MTT assay , cell cycle distribution was analyzed by flow cytometry , and alterations in signaling pathways were analyzed by western blotting . We found that sorafenib exhibited dose-dependent growth inhibition in all three EGFR-TKI-resistant NSCLC cell lines . When sorafenib was combined with gemcitabine , synergistic activity was observed in the A549 and H1666 cells and antagonistic activity was observed in the H1975 cells . Sorafenib arrested the cell cycle at the G1 phase , whereas gemcitabine arrested the cell cycle at the S phase . Sorafenib inhibited C-RAF and p-ERK in the A549 cells and B-RAF and p-ERK in the H1666 and H1975 cells . The molecular mechanism of this synergism is that RAF/MEK/ERK which are activated by gemcitabine are efficiently suppressed by simultaneously administered sorafenib . By contrast , the mechanism of antagonism may be due to mutual interference with the cell cycle in the H1975 cells . In conclusion , we found that sorafenib exhibits antiproliferative effects in EGFR-TKI-resistant NSCLC cell lines and when combined with gemcitabine demonstrates synergistic activity in A549 and H1666 cells but antagonistic activity in H1975 cells .\n OUTPUT:\n " }, { "from": "agent", "value": "evading growth suppressors;sustaining proliferative signaling" } ]

Since heavy ion beam treatment for cancer is becoming increasingly common in Japan and elsewhere , it is important to also determine their sensitivity to high-LET radiation . For this purpose we irradiated AT and normal human cells immortalized with the human telomerase gene using high- ( 24-60 keV/microm carbon and 200 keV/microm iron ions ) or low-LET ( X-rays ) radiation in non-proliferative conditions . In normal cells the RBE ( relative biological effectiveness ) of carbon and iron ions increased from 1.19 to 1.81 in proportion to LET . In contrast , their RBE in AT cells increased from 1.32 at 24 keV/microm to 1.59 at 40 keV/microm , and exhibited a plateau at over 40 keV/microm . In normal cells most gamma-H2AX foci induced by both carbon- and iron-ion beams had disappeared at 40 h . In AT cells , however , a significant number of gamma-H2AX foci were still observed at 40 h . The RBEs found in the AT cells after heavy-ion irradiation were consistent with the effects predicted from the presence of non-homologous end joining defects . The DSBs remaining after heavy-ion irradiation suggested defects in the AT cells ' DSB repair ability .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

The first determination was performed before tumour excision and the second at 6-7 months after excision . Results in patients with primary tumour in the first determination : 6 patients with over normal values in PBMCs apoptosis and 5 patients with increased values of sFas . In the second determination : apoptosis was increased in 5 patients and sFas level was increased in 4 cases . In patients with metastases in the first determination apoptosis of PBMC was increased in 7 cases and sFas in 5 cases . In the second determination apoptosis was increased in 4 cases and sFas was increased in 4 cases . Our results show that half of the investigated patients presented elevated values of PBMCs apoptosis and Fas receptor both before and 6-7 months after tumour excision . Apoptosis values for PBMCs and sFas values were with 1/4 higher than normals . There was no difference in clinical evolution of the patients with normal or increased values for studied parameters . Clinical evolution was performed for 1 year . The presence of increased values for PBMCs and sFas after tumour excision , primary or metastasis is surprising and hard to explain . It is possible that tumoral evolution induces a disregulation at PBMCs level or other cells level that persists unexpectedly , after tumour excision or apoptotic processes , in a certain level to be independent and anterior to tumour development .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;activating invasion and metastasis" } ]

In the present study , we show that the monocarboxylate transporter 2 ( MCT2 ) protein was tumor-selectively expressed in human colorectal malignancies and knockdown of MCT2 induces mitochondrial dysfunction , cell-cycle arrest , and senescence without additional cellular stress in colorectal cancer cell lines . Moreover , the reactive oxygen species ( ROS ) scavenger , N-acetylcysteine , blocked MCT2 knockdown-induced growth arrest and cellular senescence , indicating a pivotal role of ROS in this pathway . Dramatic induction of mitochondrial superoxide generation and decrease in ATP production was observed , indicating that mitochondrial dysfunction is the major mechanism underlying MCT2 knockdown-induced ROS generation . Senescence-associated DNA damage was also evident from the increase in promyelocytic leukemia bodies , γH2AX foci , and SAHF . Conversely , overexpression of MCT2 prevented doxorubicin-induced ROS accumulation ( P = 0.0002 ) and cell growth inhibition ( P = 0.001 ) . MCT2 knockdown suppressed KRAS mutant colorectal tumor growth in vivo . In addition , MCT2 knockdown and cytostatic drug combination further enhanced the antitumor effect . These findings support the use of MCT2 as a promising target for inhibition of colorectal cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;sustaining proliferative signaling;tumor promoting inflammation;genomic instability and mutation" } ]

In this study Human ovarian carcinoma cell line SKOV3 and multidrug-resistant phenotype SKVCR cells were used and the roles of autophagy in radiation-induced cell death were analyzed.Methods and materialsCell viability was examined by colony formation and cell counting kit-8 ( CCK-8 ) assay , 3MA and ZVAD were used to block autophagy and apoptosis , respectively . Quantitative real-time PCR was used to detect mRNA level and Western blot was used to detect protein expression , monodansylcadaverine ( MDC ) staining and flow cytometery were used for autophagy , apoptosis and cell cycle dynamics , respectively . RESULTS : ( 1 ) The radiosensitivity exhibited differently in SKOV3 and SKVCR cells ( SKOV3 : D0=3.37 , SKVCR : D0= 4.18 ) ; compared with SKOV3 the constitutive expression of MAPLC3 in SKVCR was higher , but no change of Caspase-3 and cleaved Caspase-3 . ( 2 ) The ionizing radiation ( IR)- induced apoptosis and autophagy were significant in both cells ( P<0.05 ) ; inhibition of apoptosis with ZVAD showed no impact on survival of SKOV3 and SKVCR cells after radiation , while inhibition of autophagy significantly decreased viability in SKVCR cells , for SKVO3 cells only low level of radiation ( 2 Gy and 4 Gy ) could decrease the viability(P<0.05) . ( 3 ) ZVAD inhibited apoptosis and autophagy in both cells , 3MA inhibit apoptosis in SKOV3 , and promote apoptosis in SKVCR , together with inhibition of autophagy . ( 4 ) G2/M arrest was induced by radiation in both cells ; the accumulation of G2/M was more significant in SKOV3 , 3MA attenuated the radiation-induced S phase delay in SKVCR . CONCLUSION : IR-induced autophagy provides a self-protective mechanism against radiotherapy in SKVCR cells , the use of autophagy inhibitor , 3MA , increases the killing effects of radiation by inhibiting autophagy and radiation- induced S phase delay , also by the increase of apoptosis , which suggests a better therapeutic strategy in drug- resistant SKVCR ovarian cancer cells .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling" } ]

However , more than 40% of those patients develop recurrences and have a poor outcome . Traditionally , the medical community has assumed that recurrent tumors arise from selected tumor clones that are refractory to therapy . However , we found that tumor cells have few phenotypical differences after surgery . Thus , we propose an alternative explanation for the resistance of recurrent tumors . Surgery promotes inhibitory factors that allow lingering immunosuppressive cells to repopulate small pockets of residual disease quickly . Recurrent tumors and draining lymph nodes are infiltrated with M2 ( CD11b(+)F4/80(hi)CD206(hi) and CD11b(+)F4/80(hi)CD124(hi) ) macrophages and CD4(+)Foxp3(+) regulatory T cells . This complex network of immunosuppression in the surrounding tumor microenvironment explains the resistance of tumor recurrences to conventional cancer vaccines despite small tumor size , an intact antitumor immune response , and unaltered cancer cells . Therapeutic strategies coupling antitumor agents with inhibition of immunosuppressive cells potentially could impact the outcomes of more than 250,000 people each year .\n OUTPUT:\n " }, { "from": "agent", "value": "avoiding immune destruction" } ]

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 .

Here we report the novel finding that Tph-1 ( tryptophan hydroxylase-1 ) , a synthase which catalyses the conversion of tryptophan to serotonin and exhausts tryptophan , is a potent regulator of immunity . In models of skin allograft tolerance , tumor growth , and experimental autoimmune encephalomyelitis , Tph-1 deficiency breaks allograft tolerance , induces tumor remission , and intensifies neuroinflammation , respectively . All of these effects of Tph-1 deficiency are independent of its downstream product serotonin .

Inhibition of PARP activity enhanced the formation of these foci , while knockdown of essential components of the base excision repair ( BER ) pathway did not . These findings suggest that PARP suppresses transcription-mediated 53BP1 foci formation , but that this does not occur through the BER pathway .

While reactive oxygen species ( ROS ) act as second messengers in RAS-induced senescence , they are also involved in oncogenic transformation by inducing proliferation and promoting mutations . In the current work , we investigated the role of extracellular superoxide dismutase ( SOD3 ) in RAS-induced senescence and immortalization in vitro and in vivo . We used a mouse embryonic fibroblast ( MEF ) primary cell model together with immortalized and transformed human cell lines derived from papillary and anaplastic thyroid cancer . Results : Based on our data , sod3 RNA interference in H-RasV12-transduced cells markedly inhibited cell growth , while sod3 over-expression in MEFs initially caused a proliferative burst followed by the activation of DNA damage checkpoints , induction of p53-p21 signal transduction , and senescence . Subsequently , sod3-transduced MEF cells developed co-operative p21-p16 down-regulation and acquired transformed cell characteristics such as increased telomerase activity , loss of contact inhibition , growth in low-nutrient conditions , and in vivo tumorigenesis . Interestingly , as reported previously with RAS , we showed a dose-dependent response to SOD3 in vitro and in vivo involving transcriptional and non-transcriptional regulatory mechanisms . Innovation : SOD3 may mediate H-RasV12-induced initiation of primary cell immortalization . Conclusions : Our results indicate that SOD3 influences growth signaling in primary and cancer cells downstream of the ras oncogene and could serve as a therapy target at an early tumorigenesis phase .\n OUTPUT:\n " }, { "from": "agent", "value": "enabling replicative immortality;evading growth suppressors;genomic instability and mutation;tumor promoting inflammation;sustaining proliferative signaling" } ]

However , a plethora of evidence demonstrated both antiestrogens exhibit agonist activities in different systems such as activation of the membrane-initiated signaling pathways . The mechanisms by which antiestrogens mediate estrogen-like activities have not been fully established . Previously , a variant of ER-α , EP-α36 , has been cloned and showed to mediate membrane-initiated estrogen and antiestrogen signaling in cells only expressing ER-α36 . Here , we investigated the molecular mechanisms underlying the antiestrogen signaling in ER-negative breast cancer MDA-MB-231 and MDA-MB-436 cells that express high levels of endogenous ER-α36 . We found that the effects of both 4-hydoxytamoxifen ( 4-OHT ) and ICI 182 , 780 ( ICI ) exhibited a non-monotonic , or biphasic dose response curve ; antiestrogens at low concentrations , elicited a mitogenic signaling pathway to stimulate cell proliferation while at high concentrations , antiestrogens inhibited cell growth . Antiestrogens at l nM induced the phosphorylation of the Src-Y416 residue , an event to activate Src , while at 5 �M induced Src-Y527 phosphorylation that inactivates Src . Antiestrogens at 1 nM also induced phosphorylation of the MAPK/ERK and activated the Cyclin D1 promoter activity through the Src/EGFR/STAT5 pathways but not at 5 �M . Knock-down of ER-α36 abrogated the biphasic antiestrogen signaling in these cells . Our results thus indicated that ER-α36 mediates biphasic antiestrogen signaling in the ER-negative breast cancer cells and Src functions as a switch of antiestrogen signaling dependent on concentrations of antiestrogens through the EGFR/STAT5 pathway .\n OUTPUT:\n " }, { "from": "agent", "value": "sustaining proliferative signaling" } ]

An abrogating effect of tissue inhibitors of metalloproteinases ( TIMP-1 and TIMP-2 ) on metastases has also been noted . In this report we have used sensitive enzyme-linked immunoassays to measure MMP-2 , MMP-9 , TIMP-1 and TIMP-2 levels in eight human lung-cancer cell lines which were characterized for biological behavior in nude mice . We demonstrated that the Calu-6 and A549 cell lines with the highest metastatic , invasive and tumorigenic potential secreted the highest levels of MMP-2 . MMP-9 and TIMP-1 secretions were comparatively low in all cell lines . TIMP-2 secretion , which exceeded MMP-2 secretion for all cell lines , did not correlate with metastatic potential . To further explore these correlations , the metastatic Calu-6 cell line was transfected with a K-rev-1 cDNA expression construct . The K-rev revertant cell lines demonstrated a more differentiated phenotype and were less tumorigenic , invasive and metastatic in nude mice . Nonetheless , the Calu-6 revertant cell lines secreted higher levels of MMP-2 than the parent cell line . In conclusion , invasion and metastasis by lung-cancer cells requires not only enhanced MMP production , but also other less well-understood tumorigenic characteristics . The multiplicity of factors required by cancer cells for dissemination helps to explain the minute fraction of cancer cells from a primary tumor that ever develop into a metastasis .\n OUTPUT:\n " }, { "from": "agent", "value": "activating invasion and metastasis" } ]

In this article , we demonstrate that G. lucidum triterpene extract ( GLT ) suppresses proliferation of human colon cancer cells HT-29 and inhibits tumor growth in a xenograft model of colon cancer . These effects of GLT are associated with the cell cycle arrest at G0/G1 and the induction of the programmed cell death Type II-autophagy in colon cancer cells . Here , we show that GLT induces formation of autophagic vacuoles and upregulates expression of Beclin-1 ( 1.3-fold increase ) and LC-3 ( 7.3-fold increase ) proteins in colon cancer cells and in tumors in a xenograft model ( Beclin-1 , 3.9-fold increase ; LC-3 , 1.9-fold increase ) . Autophagy is mediated through the inhibition of p38 mitogen-activated protein kinase ( p38 MAPK ) because p38 MAPK inhibitor , SB202190 , induces autophagy and expression of Beclin-1 ( 1.2-fold increase ) and LC-3 ( 7.4-fold increase ) , and GLT suppresses phosphorylation of p38 MAPK ( approximately 60% inhibition ) in colon cancer cells . Taken together , our data demonstrate a novel mechanism responsible for the inhibition of colon cancer cells by G. lucidum and suggest GLT as natural product for the treatment of colon cancer .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death;sustaining proliferative signaling" } ]

Cadmium ( Cd ) is a genotoxic heavy metal that has been recognized as a human carcinogen . Oxidant stress and inhibition of DNA repair have been proposed as major factors underlying Cd genotoxicity . Our previous studies indicated the ability of Cd to disturb the gene expression of MSH6 in zebrafish ( Danio rerio ) embryos . This study was undertaken to explore if Cd-induced oxidative stress down-regulated MSH gene activities . Following the exposure of zebrafish embryos at 1 h post fertilization ( hpf ) to sublethal concentrations of Cd at 3-5 μM for 4 or 9 h , a parallel down-regulation of MSH2 , MSH6 and Cu/Zn superoxide dismutase ( Cu/Zn-SOD ) gene expression was detected by real-time RT-PCR and the expression levels were 40-50% of control after a 9-h exposure . Cd exposure also induced oxidative stress , yet no inhibition of catalase gene activity was observed . Whole mount in situ hybridization revealed a wide distribution of msh6 mRNA in the head regions of 10 hpf embryos and pretreatment of embryos with antioxidants butylhydroxytoluene ( BHT ) , d-mannitol or N-acetylcysteine ( NAC ) at 1-10 μM restored Cd-suppressed msh6 expression . QPCR confirmed the protective effects of antioxidants on Cd-suppressed msh2/msh6 mRNA production . Down-regulated MSH gene activities reaching about 50% of control were also induced in embryos exposed to paraquat , a reactive oxygen species ( ROS)-generating herbicide , or hydrogen peroxide at 200 μM . Hence , Cd at sublethal levels down-regulates msh2/msh6 expression primarily via ROS as signaling molecules . The transcriptional activation of human msh6 is known to be fully dependent on the specificity factor 1 ( Sp1 ) . Cd failed to inhibit the DNA binding activity of zebrafish Sp1 unless at lethal concentrations based on band shift assay , therefore excluding the involvement of Sp1 inactivation in Cd-induced MSH gene inhibition in zebrafish embryos .\n OUTPUT:\n " }, { "from": "agent", "value": "tumor promoting inflammation" } ]

Resistance to nitrosoureas and methylating agents , which damage DNA , can be mediated by a DNA repair protein , O6-alkylguanine-DNA alkyltransferase ( AGAT ) . Depletion of this protein with alkylguanines or methylating agents , however , restores tumor cell sensitivity to the cytotoxicity of chloroethylnitrosoureas ( e.g. , carmustine [ BCNU] ) . PURPOSE This study was designed to determine whether resistance to the activity of nitrosourea ( the drug BCNU ) in BCNU-resistant human medulloblastoma ( D341 Med ) and human glioblastoma multiforme ( D-456 MG ) can be reversed by the methylating agent streptozocin and the O6-substituted guanines O6-methylguanine and O6-benzylguanine . METHODS Xenografts were grown subcutaneously in athymic BALB/c mice . BCNU was administered as a single intraperitoneal injection at doses of 100 mg/m2 , 75 mg/m2 , or 38 mg/m2--i.e. , 1.0 , 0.75 , or 0.38 , respectively , of the dose lethal to 10% of treated animals ( LD10 ) . Mice were treated intraperitoneally with a single dose of O6-benzylguanine or O6-methylguanine ( 240 mg/m2 ) or with streptozocin ( 600 mg/m2 ) daily for 4 days . Response was assessed by tumor growth delay and tumor regression . AGAT activity in the xenografts was measured at 1 and 6 hours after pretreatment , at the time tumors were excised . RESULTS Pretreatment with O6-benzylguanine , O6-methylguanine , or streptozocin reduced AGAT activity to 4% , 25% , and 95% of control values , respectively , in D341 Med and 0% , 0% , and 25% of control values , respectively , in D-456 MG 1 hour after injection . After 6 hours , levels changed to 7% , 61% , and 116% of control values in D341 Med and 0% , 79% , and 21% of control values in D-456 MG , respectively . Both D341 Med and D-456 MG xenografts were completely resistant to BCNU at its LD10 . Pretreatment with O6-benzylguanine increased BCNU sensitivity in both types of xenograft . In contrast , treatment with BCNU plus O6-methylguanine or streptozocin did not produce growth delays substantially different from those produced by BCNU alone , reflecting the more efficient depletion of AGAT by O6-benzylguanine . Following therapy with BCNU plus O6-benzylguanine at 0.38 LD10 , tumor regressions were seen in eight of 10 D341 Med and in all 10 D-456 MG xenografts . CONCLUSION We recommend comprehensive clinical toxicologic evaluation of combination therapy with O6-benzylguanine plus BCNU , which would allow subsequent design of phase I clinical trials .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]

YM155 , a novel molecular targeted agent , suppresses survivin , which is overexpressed in many tumor types . The aim of this study was to determine the antitumor activity of YM155 in SK-NEP-1 cells . METHODS : SK-NEP-1 cell growth in vitro and in vivo was assessed by MTT and nude mice experiments . Annexin V/propidium iodide staining followed by flow cytometric analysis was used to detect apoptosis in cell culture . Then gene expression profile of tumor cells treated with YM155 was analyzed with real-time PCR arrays . We then analyzed the expression data with MEV ( Multi Experiment View ) cluster software . Datasets representing genes with altered expression profile derived from cluster analyses were imported into the Ingenuity Pathway Analysis tool . RESULTS : YM155 treatment resulted in inhibition of cell proliferation of SK-NEP-1cells in a dose-dependent manner . Annexin V assay , cell cycle , and activation of caspase-3 demonstrates that YM155 induced apoptosis in SK-NEP-1 cells . YM155 significantly inhibited growth of SK-NEP-1 xenografts ( YM155 5 mg/kg : 1.45 +/- 0.77 cm3 ; YM155 10 mg/kg : 0.95 +/- 0.55 cm3 ) compared to DMSO group ( DMSO : 3.70 +/- 2.4 cm3 ) or PBS group cells ( PBS : 3.78 +/- 2.20 cm3 , ANOVA P &lt ; 0.01 ) . YM155 treatment decreased weight of tumors ( YM155 5 mg/kg : 1.05 +/- 0.24 g ; YM155 10 mg/kg : 0.72 +/- 0.17 g ) compared to DMSO group ( DMSO : 2.06 +/- 0.38 g ) or PBS group cells ( PBS : 2.36 +/- 0.43 g , ANOVA P &lt ; 0.01 ) . Real-time PCR array analysis showed between Test group and control group there are 32 genes significantly up-regulated and 54 genes were significantly down-regulated after YM155 treatment . Ingenuity pathway analysis ( IPA ) showed cell death was the highest rated network with 65 focus molecules and the significance score of 44 . The IPA analysis also groups the differentially expressed genes into biological mechanisms that are related to cell death , cellular function maintenance , cell morphology , carbohydrate metabolism and cellular growth and proliferation . Death receptor signaling ( 3.87E-19 ) , TNFR1 signaling , induction of apoptosis by HIV1 , apoptosis signaling and molecular mechanisms of cancer came out to be the top four most significant pathways . IPA analysis also showed top molecules up-regulated were BBC3 , BIRC3 , BIRC8 , BNIP1 , CASP7 , CASP9 , CD5 , CDKN1A , CEBPG and COL4A3 , top molecules down-regulated were ZNF443 , UTP11L , TP73 , TNFSF10 , TNFRSF1B , TNFRSF25 , TIAF1 , STK17A , SST and SPP1 , upstream regulator were NR3C1 , TP53 , dexamethasone , TNF and Akt . CONCLUSIONS : The present study demonstrates that YM155 treatment resulted in apoptosis and inhibition of cell proliferation of SK-NEP-1cells . YM155 had significant role and little side effect in the treatment of SK-NEP-1 xenograft tumors . Real-time PCR array analysis firstly showed expression profile of genes dyes-regulated after YM155 treatment . IPA analysis also represents new molecule mechanism of YM155 treatment , such as NR3C1 and dexamethasone may be new target of YM155 . And our results may provide new clues of molecular mechanism of apoptosis induced by YM155 .\n OUTPUT:\n " }, { "from": "agent", "value": "resisting cell death" } ]

Mutations in colonic adenomas , and the frequent losses on 4q described in gastric cancer prompt speculation about the role of CDC4/FBXW7 in gastric carcinogenesis . METHODS We assessed the role of CDC4/FBXW7 in gastric cancer , through loss of heterozygosity ( LOH ) and multiplex ligation-dependent probe amplification ( MLPA ) on 47 flow-sorted gastric carcinomas including early-onset gastric cancers ( EOGC ) and xenografted conventional gastric carcinomas . Ploidy analysis was carried out on 39 EOGCs and immunohistochemistry of CDC4/FBXW7 and its substrates c-myc , c-jun , Notch and cyclin E was performed on 204 gastric carcinomas using tissue microarrays ( TMAs ) . Sequence analysis of CDC4/FBXW7 was carried out on gastric carcinoma cell lines and xenografts . RESULTS Loss of heterozygosity of CDC4/FBXW7 occurred in 32% of EOGCs , and correlated with loss of expression in 26% . Loss of expression was frequent in both EOGC and conventional gastric cancers . No CDC4/FBXW7 mutations were found and loss of CDC4/FBXW7 did not correlate with ploidy status . There was a significant correlation between loss of CDC4/FBXW7 expression and upregulation of c-myc . CONCLUSION Loss of CDC4/FBXW7 appears to play a role in both EOGC and conventional gastric carcinogenesis , and c-myc overexpression is likely to be an important oncogenic consequence of CDC4/FBXW7 loss .\n OUTPUT:\n " }, { "from": "agent", "value": "genomic instability and mutation" } ]
