摘要 结肠直肠癌发病率在我国有上升趋势,化疗耐药是导致结肠直肠癌治疗失败的主要原因之一。而引起恶性肿瘤化疗耐药的多方面因素中缺氧微环境是一重要原因,大量研究表明实体癌存在不同程度的缺氧,缺氧可诱导核转录因子——缺氧诱导因子-1(Hypoxia Inducible Factor-1,HIF-1)表达增高,从而上调下游靶基因的表达,其中也包括多药耐药基因1(Multidrug Resistance Gene 1,mdr1)编码的膜蛋白P糖蛋白(P-Glycoprotein,P-Gp)。本研究应用免疫组化方法检测了人结肠直肠癌组织中HIF-1α及耐药相关蛋白P-Gp的表达,旨在探讨P-Gp在结肠直肠癌中的表达情况及其与HIF-1α的关系。
