缺氧诱导因子-1α在子宫内膜异位症的表达及意义

目的 检测缺氧诱导因子-1α(HIF-1α)在子宫内膜异位症(EMs)中的表达,探讨其在EMs发病机制中的作用.方法 取68例EMs的异位内膜、20例在位内膜和20例正常子宫内膜标本,用免疫组化SP法检测HIF-1α蛋白的表达情况,并用组织学评分对其结果进行半定量统计,比较其表达强度.结果 HIF-1α主要定位于腺上皮细胞的胞浆中.EMs患者中异位内膜组表达强度显著高于在位内膜组及对照组(P＜0.01),各组中分泌期与增生期表达强度比较无显著性差异(P＞0.05).结论 HIF-1α在EMs患者中的表达显著升高,推测HIF-1α与EMs的发病密切相关.

Expression of hypoxia-inducible factor-1α in endometriosis

OBJECTIVE: To detect the expression of hypoxia-inducible factor-1alpha(HIF-1alpha) in endometriosis and explore the possible role of HIF-1alpha in the pathogenesis of endometriosis. METHODS: Immunohistochemistry was performed to examine the expression of HIF-1alpha in 20 normal endometrium, 20 ectopic endometrium and 68 eutopic endometrium specimens from 68 endometriosis patients, and the results were analyzed statistically. RESULTS: The expression of HIF-1alpha was significantly increased in ectopic endometrium than in normal endometrium (P<0.01), and the expression did not undergo changes with the normal menstrual cycle in the three types of endometrium. CONCLUSION: HIF-1alpha expression increases in ectopic endometrium, suggesting that HIF-1alpha plays an important role in the pathogenesis of endometriosis.
