miRNA是一种内源性的起重要调控功能的非编码RNA,发现能起到抑癌作用的miRNA对理解癌症的基因调控网络、发展新的癌症干预方法重要的意义。能对在癌组织中发生差异表达的基因起到广泛调控作用的miRNA可以被认为是与癌的发生发展相关的miRNA,但由于癌细胞中调控网络的复杂性,直接分析miRNA靶基因在差异表达基因中的富集度通常得不到统计显著的侯选miRNA。本文认为,相对于差异表达基因, 差异基因表达模块更能反映在癌症细胞中基因网络发生差异变化的主要部分 ,能显著调控差异基因表达模块的miRNA更可能在癌细胞中起到关键调控作用。主要方法与发现如下: 1、本文先利用研究小组自己开发的基因模块识别方法ClustEx找到在结肠癌中(癌组织vs癌旁组织的基因表达谱+蛋白质相互作用网络)发生变化的差异基因表达模块; 2、通过分析miRNA靶基因在差异基因表达模块中的富集度来推断起关键调控作用的miRNA; 3、结合miRNA表达谱,在结肠癌中低表达的miRNA被认为更可能起到抑癌的作用。 基于上述分析,我们识别了三个抑癌的miRNA:miR-139, -101, -124。其中miR-139 q-value最显著,且bootstrapping稳定性最高。后续分子实验证明 miR-139可显著抑制结肠癌细胞生长,而促癌转录因子ETS1是其直接靶基因 。在TCGA数据集中可观察到miR-139在癌症早期阶段(pathologic stage)即显著下调。(注:在论文投稿过程中陆续有miR-139论文发表,其中NOTCH1在我们预测的核心靶基因集合中)。 核心思想就是通过分析miRNA靶基因在差异基因表达模块中的富集度来进行推断(Module-based Master Regulator Inference, ModMRI) 。该方法的思想具有普适性:推断上游关键调控节点最有效的方法是观测其下游靶基因的行为,而不是仅仅观测其自身的变化。 =========================================================================== Gene module based regulator inference identifying miR-139 as a tumor suppressor in colorectal cancer . Molecular BioSystems 2014, In Press. Jin Gu*#, Yang Chen*, Huiya Huang, Lingyun Yin, Zhen Xie, Michael Zhang#. Colorectal cancer is one of the most commonly diagnosed cancer types worldwide. Identifications of the key regulators of the altered biological networks are crucial for understanding the complex molecular mechanisms of colorectal cancer. We proposed a gene module based approach to infer key miRNAs regulating the major gene network alterations in cancer tissues. By integrating gene differential expression and co-expression information with protein-protein interaction network, the differential gene expression modules, which captured the major gene networks changes, were identified for colorectal cancer. Then, several key miRNAs, which extensively regulate the gene modules, were inferred by analyzing their target gene enrichments in the modules. Among the inferred candidates, three miRNAs, miR-101, miR-124 and miR-139 are frequently down-regulated in colorectal cancers. The following computational and experimental analyses demonstrate that miR-139 can inhibit cell proliferation and cell cycle G1/S transition. A known oncogene ETS1, a key transcription factor in the gene module, was experimentally verified as a novel target of miR-139. MiR-139 was found significantly down-regulated in early pathologic cancer stages and its expressions remained at very low levels in advanced stages. These results indicate that miR-139, inferred by the gene module based approach, should be a key tumor suppressor in early cancer development.

结肠癌是由细菌引发的吗?2011年10月份,两个研究小组发布了几乎相同的报告,指出一种名为“梭杆菌”(Fusobacteria)的细菌很不寻常,它们平常很少出现在人体肠道内,但是研究发现它们在结肠癌细胞中却异常活跃,并且似乎显示它们与肿瘤的恶性程度存在相关性。将健康的结肠组织和癌变组织进行对比,科学家们注意到这种细菌明显地集中并活跃于癌变细胞中,在一部分样本中,这种差异甚至达到了上百倍。 这是人们首次开始注意到这种细菌与癌症之间可能存在的关联性,但在此前,医学界已经留意到这种细菌似乎和溃疡性结肠炎的发生存在关联。 http://news.sciencenet.cn/htmlnews/2011/12/256775-2.shtm

The study, published Tuesday in Cancer Prevention Research , found a link between daily ginger supplements and a reduction of inflammation in the colon, which researchers suggest is one step toward better understanding the role ginger root might play in preventing colon cancer. Prior studies in mice and rats have shown that ginger helped prevent the formation of tumors when the animals were exposed to a chemical that causes colon cancer. For the new study, researchers from the University of Michigan Medical School in the US randomly assigned 30 healthy adults to take capsules containing either 2 grams of powered ginger root (about two tablespoons of ground-up ginger root, noted the researchers) or a placebo powder every day for four weeks. Before and after the study, the researchers took tissue samples from the lining of the colon. They "tested these samples for chemicals called eicosanoids that increase inflammation in the gut," stated WebMD, noting that the ginger-eating subjects showed reduced inflammation. Another recent study published in The Lancet found that low doses of aspirin, taken daily and over the long term, cut cases of colorectal cancer by a quarter and the death toll from this disease by a third.
低剂量阿司匹林或可预防结肠癌 英国研究者发现,长期服用低剂量阿司匹林不仅可降低心脏病发作和中风几率,而且可降低患结肠癌的风险。 英国牛津约翰拉德克利夫医院研究者彼得罗思韦尔领导的研究团队在过去20年间对 1.4万名英国人展开临床试验。所有研究对象中,一半人长期服用用以降低心脏病发作风险的低剂量阿司匹林。18年后,研究者发现,长期服用低剂量阿司匹林 可使患结肠癌几率降低24%,使死于结肠癌的几率降低35%。 这一研究成果发表在最新一期《柳叶刀》杂志上。路透社10月21日援引文章内容报道说:这一有趣的研究将给医学研究者重要提示,对于患结肠癌的高风险人群,可以使用阿司匹林作为预防方案。 口服阿司匹林广泛应用于心脏病和中风等疾病的防治。但医疗人员同时发现,对某些特定人群,阿司匹林可能引发胃出血和肠出血。先前,医学研究者发现,长期口服低剂量镇痛类药物布洛芬也可降低患结肠癌的几率。(来源:新华网) http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2810%2961543-7/fulltext#article_upsell Long-term effect of aspirin on colorectal cancer incidence and mortality: 20-year follow-up of five randomised trials Original Text Prof Peter M Rothwell FMedSci a , Michelle Wilson BSc a , Carl-Eric Elwin MD b , Prof Bo Norrving PhD c , Prof Ale Algra MD d , Prof Charles P Warlow FMedSci e , Prof Tom W Meade FRS f Summary Background High-dose aspirin (500 mg daily) reduces long-term incidence of colorectal cancer, but adverse effects might limit its potential for long-term prevention. The long-term effectiveness of lower doses (75300 mg daily) is unknown. We assessed the effects of aspirin on incidence and mortality due to colorectal cancer in relation to dose, duration of treatment, and site of tumour. Methods We followed up four randomised trials of aspirin versus control in primary (Thrombosis Prevention Trial, British Doctors Aspirin Trial) and secondary (Swedish Aspirin Low Dose Trial, UK-TIA Aspirin Trial) prevention of vascular events and one trial of different doses of aspirin (Dutch TIA Aspirin Trial) and established the effect of aspirin on risk of colorectal cancer over 20 years during and after the trials by analysis of pooled individual patient data. Results In the four trials of aspirin versus control (mean duration of scheduled treatment 60 years), 391 (28%) of 14033 patients had colorectal cancer during a median follow-up of 183 years. Allocation to aspirin reduced the 20-year risk of colon cancer (incidence hazard ratio 076, 060096, p=002; mortality HR 065, 048088, p=0005), but not rectal cancer (090, 063130, p=058; 080, 050128, p=035). Where subsite data were available, aspirin reduced risk of cancer of the proximal colon (045, 028074, p=0001; 034, 018066, p=0001), but not the distal colon (110, 073164, p=066; 121, 066224, p=054; for incidence difference p=004, for mortality difference p=001). However, benefit increased with scheduled duration of treatment, such that allocation to aspirin of 5 years or longer reduced risk of proximal colon cancer by about 70% (035, 020063; 024, 011052; both p00001) and also reduced risk of rectal cancer (058, 036092, p=002; 047, 026087, p=001). There was no increase in benefit at doses of aspirin greater than 75 mg daily, with an absolute reduction of 176% (061291; p=0001) in 20-year risk of any fatal colorectal cancer after 5-years scheduled treatment with 75300 mg daily. However, risk of fatal colorectal cancer was higher on 30 mg versus 283 mg daily on long-term follow-up of the Dutch TIA trial (odds ratio 202, 070605, p=015). Interpretation Aspirin taken for several years at doses of at least 75 mg daily reduced long-term incidence and mortality due to colorectal cancer. Benefit was greatest for cancers of the proximal colon, which are not otherwise prevented effectively by screening with sigmoidoscopy or colonoscopy.
http://www.sciencenet.cn/htmlnews/2009/8/222704.shtm 研究找到结肠癌发生中新的信号通路 由哈尔滨医科大学青年教师佟丹丹博士完成的一项课题《结肠癌中RUNX3表达及其与TGF-信号通路关系的研究》,在国内外首次从细胞实验角度证实:抑癌基因RUNX3能通过依赖TGF-和非依赖TGF-两条途径,抑制结肠癌细胞生长并诱导癌细胞死亡。该成果为人们探讨结肠癌的发病机制和指导临床治疗提供了新的认识及方向。 结直肠癌是人类常见的恶性肿瘤,除了与饮食因素有关外,还与抑癌基因失去活性、转化生长因子(TGF-)信号通路调节紊乱等多种因素相关。人类RUNX3基因于1994年发现,最初被命名为急性髓性白血病基因,以后又被称作多瘤病毒强化因子结合蛋白基因。作为一种抑癌基因,其活性减弱或消失均可导致结肠癌的发生。了解它怎样通过调节TGF-信号通路和促进结肠癌的发生,对揭示结肠癌演进奥秘十分必要。 TGF-是一种具有广泛生物学活性的细胞因子,几乎作用于所有细胞,控制细胞的一系列生命活动。一旦TGF-的信号通路发生改变,能引起多种疾病。近年来的报道表明,TGF-在人类多种肿瘤如胃肠道肿瘤、乳腺癌、卵巢癌和神经内分泌肿瘤的恶性转化、浸润及转移中均扮演重要角色,且能影响肿瘤细胞对化疗的敏感程度。RUNX3作为TGF-信号通路中的重要蛋白,参与对上皮细胞生长进行负调控。 在前期科研工作中,佟丹丹在哈医大肿瘤医院病理科主任耿敬姝教授指导下,首次发现依赖TGF-途径可抑制肿瘤细胞增殖。在此基础上,更加深入地探寻RUNX3可否通过其他途径抑制肿瘤细胞生长和增殖。期间,佟丹丹博士从结肠癌细胞系入手,深入开展实验研究,采用多种分子生物学手段,用TGF-刺激肿瘤细胞,在不同的时间点观察肿瘤细胞的生长、增殖状态,并检测TGF- 信号通路中蛋白的表达,最终成功地确定RUNX3基因不但能通过依赖TGF-途径,还可以通过不依赖TGF-两条途径发挥作用。 RUNX3 inhibits cell proliferation and induces apoptosis by TGF - beta -dependent and -independent mechanisms in human colon carcinoma cells.

The TGF - beta -resistant human colon cancer cell line HT-29 has inactivated TbetaRII and deficient expression of RUNX3 and Smad4 , which are involved in the TGF - beta signaling pathway. METHODS: Western blot and immunocytochemistry were performed to confirm gene expression, the MTT assay to detect cell growth , flow cytometry to investigate the cell cycle and the TUNEL to detect cell apoptosis. RESULTS: In the absence of TGF - beta , Bim was upregulated, cell growth was inhibited and apoptosis was induced. TGF - beta treatment did not affect RUNX3 expression; however, the increase in Bim expression was significant and time dependent. Interestingly, Smad4 but not Smad2 /3 was also upregulated upon exposure to TGF - beta . This was not the case after TGF - beta treatment of parent HT-29 cells. As expected, TGF - beta further inhibited cell growth and induced apoptosis in HT-29/ RUNX3 + cells. CONCLUSION: Our data demonstrate that RUNX3 is involved in TGF - beta -dependent and -independent cell growth inhibition and apoptosis induction pathways.

PMID: 19682550 Related Articles Authors: Subramaniam, M M , Chan, J Y , Yeoh, K G , Quek, T , Ito, K , Salto-Tellez, M Journal: Biochim Biophys Acta , 2009 Abstract: A major goal of molecular biology is to elucidate the mechanisms underlying cancer development and progression in order to achieve early detection, better diagnosis and staging and novel preventive and therapeutic strategies. We feel that an understanding of Runt-related transcription factor 3 ( RUNX3 )-regulated biological pathways will directly impact our knowledge of these areas of human carcinogenesis. The RUNX3 transcription factor is a downstream effector of the transforming growth factor - beta ( TGF - beta ) signaling pathway, and has a critical role in the regulation of cell proliferation and cell death by apoptosis, and in angiogenesis, cell adhesion and invasion. We previously identified RUNX3 as a major gastric tumor suppressor by establishing a causal relationship between loss of function and gastric carcinogenesis. More recently, we showed that RUNX3 functions as a bona fide initiator of colonic carcinogenesis by linking the Wnt oncogenic and TGF - beta tumor suppressive pathways. Apart from gastric and colorectal cancers, a multitude of epithelial cancers exhibit inactivation of RUNX3 , thereby making it a putative tumor suppressor in human neoplasia. This review highlights our current understanding of the molecular mechanisms of RUNX3 inactivation in the context of cancer development and progression.

Three mammalian runt-related genes, RUNX1 , RUNX2 and RUNX3 , have been described. RUNX3 has been shown to be a putative tumor suppressor gene localized to chromosome 1p36, a region showing frequent loss of heterozygosity events in colon, gastric, breast and ovarian cancers. Because of the important role of TGF - beta signaling in the human colon, we hypothesized that RUNX3 may serve as a key tumor suppressor in human colon cancers and colon cancer -derived cell lines. We examined RUNX3 expression and the frequency of RUNX3 promoter hypermethylation in 17 colon cancer cell lines and 91 sporadic colorectal cancers. Semiquantitative analysis of RUNX3 transcripts was performed by RT-PCR and de novo methylation of the RUNX3 promoter was studied by a methylation-specific PCR (MSP) assay. Nineteen of 91 informative tumors (21%) and 11 of 17 (65%) colon cancer cell lines exhibited hypermethylation of the RUNX3 promoter. Interestingly, RUNX3 promoter hypermethylation was more common in tumors exhibiting high frequency of microsatellite instability (MSI-H) (33% of MSI-H vs. 12% of MSI-L/MSS tumors; p = 0.012). Hypermethylation of the RUNX3 promoter correlated with loss of mRNA transcripts in all cell lines. RUNX3 promoter methylation was reversed and its expression restored in SW48 and HCT15 colon cancer cells after treatment with the demethylating agent 5-aza-2'-deoxycytidine, indicating that loss of expression is caused by epigenetic inactivation in colon carcinogenesis. This is the first demonstration of frequent de novo hypermethylation of the RUNX3 promoter in sporadic colon cancers. The significant association of RUNX3 promoter hypermethylation with MSI -H colon cancers suggests that RUNX3 is a novel target of methylation, along with the hMLH1 gene, in the evolution of MSI-H colorectal cancers.
