The injection of DHEA induced polycystic ovary syndrome (PCOS) model in rats. a Body weight of rats in each group, n = 5 in each group; b Enzyme-linked immunosorbent assay (ELISA) was used for testing testosterone (T), estradiol (E₂), progesterone(P), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) levels of the rats in each group, and the ratio of LH/FSH was calculated, n = 5 in each group; c The histomorphology of ovary tissues in rats was observed by hematoxylin-eosin staining (magnification ×40, 400); d Quantitative real-time PCR (qRT-PCR) was used for testing lncRNA SNHG12, miR-129, and miR-125b mRNA expression in rats in each group, n = 3 in each group; ^▲P < 0.05, ^▲▲P < 0.01 vs. control group
