摘要 目的通过检测低氧诱导因子-1α(HIF-1α)、多耐药基因1(MDR1)在人宫颈癌组织、He La细胞中的表达及两者间的关系,探讨低氧微环境与宫颈癌耐药的关系。方法应用免疫组化法检测78例中、晚期宫颈癌组织微阵列芯片组织标本中HIF-1α、MDR1的表达;以二氯化钴(Co Cl2)处理He La细胞模拟细胞低氧微环境,设置低氧组、常氧组。细胞免疫荧光法检测HIF-1α、MDR1蛋白在He La细胞中表达。结果 HIF-1α、MDR1在宫颈癌组织中的阳性表达率分别为69.2%、85.6%,且表达呈正相关(r=0.348,P<0.05)。低氧组He La细胞HIF-1α、MDR1表达分别为34.76±7.09、57.61±57.61,显著高于常氧组的19.46±3.57、29.57±12.85(P<0.05),低氧组HIF-1α与MDR1表达呈正相关(r=0.315,P<0.05)。结论低氧微环境与宫颈癌耐药发生有关,可能的机制是HIF-1α促进MDR1的表达从而导致耐药的发生。
