The aim of this study is to investigate the expression of miR-155 in colonic cancer tissue and to assess the potential predictive value of miR-155 in colonic cancer patients.
From March to September of 2011, we included 57 patients with primary colonic cancer who underwent curative surgical resection. Total RNAs were extracted from colonic cancer tissues and adjacent normal tissues. Then the expression of miR-155 in colonic cancer and paracancerous tissues was investigated using real time quantitative reverse transcription-polymerase chain reaction. And the relationship between miR-155 expression level and the clinical, pathological parameters of colonic cancer was analyzed.
The relative expression level of miR-155 in colonic cancer tissues was significantly higher than that in paracancerous tissues and related to tumor-node-metastasis staging, tumor invasion, metastasis, and differentiation.
The expression of miR-155 is up-regulated in colonic cancer tissues. MiR-155 may acts as proto-oncogenes involved in carcinogenesis, development, and invasion of colon cancer making it a potential target for gene therapy of colon cancer.
本研究旨在探讨miR-155在结肠癌组织中的表达情况,并评估miR-155对结肠癌患者的潜在预测价值。
2011年3月至9月,我们纳入了57例行根治性手术切除的原发性结肠癌患者。从结肠癌组织和癌旁正常组织中提取总RNA。然后采用实时定量逆转录-聚合酶链反应研究miR-155在结肠癌及癌旁组织中的表达情况。并分析miR-155表达水平与结肠癌临床、病理参数之间的关系。
miR-155在结肠癌组织中的相对表达水平显著高于癌旁组织,且与肿瘤-淋巴结-转移分期、肿瘤侵袭、转移及分化相关。
miR-155在结肠癌组织中表达上调。miR-155可能作为原癌基因参与结肠癌的发生、发展和侵袭,使其成为结肠癌基因治疗的潜在靶点。
