摘 要:Objective:To study the effect of estrogen on anovulatory dysfunctional uterine bleeding(ADUB).Methods:Primary endometrial epithelial cells of Hainan Lizu female was cultured and hydrolylic activity of gelalinase was determined by gelatin zymography *** mRNA and protein synthesis was blocked respectively to determine whether the increased expression of MMP-2/9 was induced by *** expression of VEGF was blocked by *** treatment with various ***-9,VEGF,total Erk and phosphorylated Erk expression in primary uterine epithelial cells was detected by Western blotting *** MMP-2/9mRNA levels was measured by real-time ***:The activity and expression of MMP2/9 was inereased in the endometrium of patients with *** could up-regulate the expression of VEGF and activate Erk 1/2-Elk1 signal *** interference by siRNA,ERK1/2 pathway was blocked in cells,and the expression of MMP-2/9 was ***1/2 specific blocker U0126 blocked ERK phosphorylation,and it could down-regulate the expression of MMP-2/***:The results showed that the estrogen can increase the expression of VEGF,and thus activate ERK1/2 pathway to induce MMP-2/9 expression.
