The expression of the three candidate genes (PWRN2, miR-92b-3p and TMEM120B) in cumulus cell according to oocyte nuclear maturity (CCMI/GV and CCMII) in patients with PCOS (n = 30) were detected by qRT-PCR to validate the potential ceRNA network. This evidence concerns the gene PWRN2 and polycystic ovary syndrome.
