摘要 目的探讨microRNA21在胃癌发生发展中的作用。方法采用茎环实时定量PCR法检测117份胃癌组织标本和癌旁正常组织标本中microRNA21的表达水平;分析其与胃癌临床病理因素的关系。结果 microR-NA21在胃癌组织中相对表达水平显著高于癌旁正常组织(P<0.000 1)。相关分析显示,microRNA21高表达与胃癌临床分期、浸润深度、分化程度及淋巴结转移呈正相关(P均<0.05),与肿瘤部位(胃窦、胃体和贲门胃底)无明显相关性。结论 microRNA21在胃癌组织中表达上调;其高表达可促进胃癌的发生发展;microRNA21有望作为一个新的潜在生物学标记物用于胃癌的早期诊断及预后判断。
