摘要 目的检测原发性结肠癌组织中miR-21基因的表达,并探讨其表达与临床病理因素的相关性。方法采用实时定量PCR的方法检测112例原发性结肠癌组织和对应正常结肠组织中miR-21的相对表达差异,根据患者年龄、性别、病理分型以及Dukes分期将患者分组,分析miR-21的组织表达差异与临床病理因素间的关系。结果实时定量PCR结果显示,相对于癌旁正常结肠组织,miR-21在82.1%(92/112)的结肠癌组织中呈高表达状态,miR-21在结肠癌组织中的表达差异与患者性别、年龄以及临床病理分型差异无统计学意义(>0.05);随着Dukes分期的增加,miR-21在癌组织中的表达呈增加趋势。结论 miR-21的表达在原发性结肠癌组织中较癌旁正常组织显著增加,对结肠癌临床分期和病理诊断具有重要的意义。
