Abstract: Objective:To investigate the expressions of miR23b and Sp1 in ovarian endometriosis and their clinic significance.Methods:qPCR was used to detect the expression of miR23b and Sp1 mRNA in paired ectopic/eutopic and normal endometrium.Immunohistochemistry and Western bolt were used to determine the expression and distribution of Sp1 in paired ectopic/eutopic and normal endometrium.The association ofmiR23b and Sp1 with the endometriosis was analyzed.Results:MiR23b mRNA expression in paired ectopic/eutopic and normal endometrium was gradually increased (P＜0.05).Sp1 protein mainly distributed in the nucleus of endometrial glandular epithelial and stromal cells,with a little or without expression in cytoplasm.Spl mRNA and protein expression in paired ectopic/eutopic and normal endometrium was gradually reduced (P＜0.05).Pearson correlation analysis showed that miR23b was negatively correlated with Sp 1 (r=-0.526,P＜0.05).Conclusion:MiR23b and Sp1 are involved in the pathogenesis of ovarian endometriosis,which may facilitate the formation of ectopic lesions.
