Integrin β1, MMP-2, and PRL-3 expression were significantly higher in ectopic endometrial tissues compared to eutopic and control tissues from patients with endometriosis.

Abstract

目的探讨整合素B1(Intβ1)、基质金属蛋白酶-2(MMP-2)及促肝细胞再生磷酸酶.3(PRL.3)在子宫内膜异位症(EMS)中的表达。方法选取EMS患者异位内膜30例、在位内膜20例和子宫肌瘤患者非瘤区子宫内膜组织20例(对照内膜),应用免疫组织化学方法检测各组织中Intβ1、MMP-2及PRL-3的表达水平。结果Intβ1、MMP-2和PRL-3在异位内膜中的表达明显高于在位内膜和对照内膜(P均〈0.01)。在对照内膜分泌期Intβ1表达强于增生期(P〈0.05);在异位内膜分泌期MMP-2表达高于增生期(P〈0.05);PRL-3增生期和分泌期表达三组均无周期性变化。在异位内膜组织内,Intβ1、MMP-2在R—AFS分期I-Ⅱ期表达低于Ⅲ~Ⅳ期(P〈0.05);PRL-3的表达在I-Ⅱ期高于Ⅲ~Ⅳ期(P〈0.05)。结论Intβ1、MMP-2及PRL-3在异位内膜组织中表达增高。
