SUMMARY ANSWER: miR-503 expression is downregulated in ECSCs by DNA hypermethylation and this contributes to their proliferation, resistance to apoptosis, extracellular matrix (ECM) contractility and angiogenesis through effects on cyclin D1, B-cell lymphoma/leukemia (Bcl)-2, Ras homology A and vascular endothelial growth factor A (VEGF-A).","subitem_description_language":"en"},{"subitem_description":"What is known already: A variety of miRNAs are demonstrated to involve in the pathogenesis of endometriosis. miR-503 is a miRNA with tumor-suppressor functions, whose expression is suppressed in ECSCs.","subitem_description_language":"en"},{"subitem_description":"Study design, size, duration: We isolated ECSCs and normal endometrial stromal cells (NESCs) from ovarian endometriotic tissues (n = 32) and eutopic endometrial tissues without endometriosis (n = 8), respectively.","subitem_description_language":"en"},{"subitem_description":"Participants/materials, setting, methods: We investigated the functions of miR-503 by using miR-503-transfected ECSCs and the DNA methylation status of miR-503 gene in ECSCs and NESCs by combined bisulfite restriction analysis.","subitem_description_language":"en"},{"subitem_description":"Main results and the role of chance: In ECSCs, miR-503 is downregulated by the DNA hypermethylation of its gene. The transfection of miR-503 into ECSCs resulted in the inhibition of cell proliferation and induction of cell-cycle arrest at G0/G1 phase through the suppression of cyclin D1, the induction of apoptosis through Bcl-2 suppression, the inhibition of VEGF-A production and the attenuation of ECM contractility via the suppression of Rho/Rho-associated coiled-coil-forming protein kinase-pathways.","subitem_description_language":"en"},{"subitem_description":"Large scale data: NA.","subitem_description_language":"en"},{"subitem_description":"Limitations, reasons for caution: The present experiments were carried out only with the stromal component of endometriosis and eutopic endometrium.
