Abstract
Endometriosis is an estrogen-dependent disease that is characterized by pelvic pain and infertility. MicroRNAs have been shown to implicate in the progression of endometriosis. In our study, we used real-time PCR to evaluate the expression of miR-141-3p in endometrial samples. In addition, western blot analysis was used to assess the expression of Krüppel-like factor 12 (KLF-12). The proliferation and migration of ectopic endometrial stromal cells (ESCs) were determined by MTT assay and Transwell assay, respectively. Cell apoptosis was evaluated using a Cell Death Detection ELISA Plus kit. The results showed that miR-141-3p and KLF-12 were significantly different in paired ectopic and eutopic endometrial samples. miR-141-3p overexpression significantly restrained the proliferation and migration and promoted the apoptosis of ectopic ESCs, whereas a decreased level of miR-141-3p was associated with opposite results. Furthermore, dual-luciferase reporter assay confirmed that KLF-12 was a novel target of miR-141-3p, while it also decreased the effects of miR-141-3p on the proliferation, apoptosis, and migration of ectopic ESCs. Our data suggested that enhanced expression of miR-141-3p suppressed the proliferation and migration of ectopic ESCs and promoted their apoptosis via targeting KLF-12. Our results may provide a novel potential therapeutic target for the treatment of endometriosis.
