Role of transforming growth factor β‑1 in the pathogenesis of pelvic organ prolapse: A potential therapeutic target.

ABSTRACT: The present study aimed to reveal the metabolic alterations of the extracellular matrix (ECM) in uterosacral ligament (USL) with pelvic organ prolapse (POP) and to explore the role of transforming growth factor‑β1 (TGF‑β1) in pathogenesis of POP. For this purpse, 60 participants who underwent hysterectomy for benign indications were enrolled, 30 of which had symptomatic POP (grade II, III or IV) and composed the POP group, and the other 30 had asymptomatic POP (grade I or less) and served as the controls. Collagen fibers, elastin,matrix metalloproteinase (MMP)‑2/9, tissue inhibitor of matrix metalloproteinases (TIMP)‑2 and TGF‑β1 were examined by Masson's trichrome staining, immunohistochemistry and RT-qPCR using USL biopsies. In vitro, human USL fibroblasts (hUSLFs) were primary cultured,
