摘要 目的探讨缺氧诱导因子-1α(HIF-1α)及其下游靶基因CXCR4、VEGF在子宫内膜非典型增生及子宫内膜癌中的表达,分析其在子宫内膜癌发生发展中的作用,及与患者临床病理参数和预后的关系。方法分别采用RT-PCR和EnVision-免疫组化染色技术检测86例子宫内膜癌组织、25例子宫内膜非典型增生组织、25例正常子宫内膜组织中HIF-1α及其下游靶基因CXCR4、VEGF的mRNA和蛋白表达。结果 HIF-1α、CXCR4、VEGF mRNA和蛋白在子宫内膜癌组织、子宫内膜非典型增生组织中存在高表达,而在正常子宫内膜组织中呈低表达或无表达。其中HIF-1α和CXCR4蛋白表达在子宫内膜癌组织、子宫内膜非典型增生组织中的表达与正常子宫内膜组织比较差异有统计学意义(P<0.05)。HIF-1α和CXCR4的表达水平与子宫内膜癌患者的肿瘤临床分期、脉管浸润等重要的临床病理参数及患者术后生存时间相关。结论 HIF-1α及其下游靶基因CXCR4、VEGF在子宫内膜癌和子宫内膜非典型增生组织中呈高表达,且HIF-1α和CXCR4与肿瘤临床分期、脉管浸润等临床病理参数和预后相关。
