Proteomic Alterations in Follicular Fluid of Human Small Antral Follicles Collected from Polycystic Ovaries-A Pilot Study.

ABSTRACT: Polycystic ovaries (PCO) contain antral follicles that arrest growing around 3-11 mm in diameter, perturbing the dominant follicle's selection and the subsequent ovulatory process. Proteomic alterations of PCO follicular fluid (FF) (i.e., microenvironment in which the oocyte develops until ovulation) have been studied from large follicles in connection with oocyte pickup during ovarian stimulation. The present study aimed to detect proteomic alterations in FF from unstimulated human small antral follicles (hSAF) obtained from PCO. After performing deep-sequencing label-free proteomics on 10 PCO and 10 non-PCO FF samples from unstimulated hSAF (4.6-9.8 mm), 1436 proteins were identified, of which 115 were dysregulated in PCO FF samples.
