目的 探討胃癌組織中Runt相關轉錄因子3(Runx3)基因的表達情況及其與胃癌臨床病理學因素的關系。方法 采用逆轉錄-聚合酶鏈反應(RT-PCR)和蛋白印跡(Western blot)法分別檢測52例胃癌組織和配對的正常胃黏膜組織中Runx3 mRNA以及蛋白的表達水平,并分析Runx3表達與胃癌臨床病理學因素的關系。結果 59.6%(31/52)的胃癌組織出現(xiàn)Runx3 mRNA表達缺失,48.1%(25/52)出現(xiàn)Runx3蛋白表達缺失,其缺失率均明顯高于對應的正常胃黏膜組織(P<0.05)。Runx3的表達缺失與腫瘤大小、組織分化程度、浸潤深度、淋巴結轉移及TNM分期有關(P<0.05,P<0.01)。Runx3 mRNA表達與蛋白表達呈正相關(r=0.840,P<0.01)。結論 Runx3基因與胃癌的發(fā)生、發(fā)展密切相關,有望成為胃癌診斷和治療的新靶點。
