摘要
FuFang ZhenZhu TiaoZhi (FTZ) is a hospitalized traditional Chinese medicine herbal formula with documented metabolic benefits. Polycystic ovary syndrome (PCOS) characterized by ovarian dysfunction and insulin resistance represents one of the most common endocrine disorders in close association with metabolic dysfunction in premenopausal women. Aim of The Study: The present study aimed to investigate the preventive effect of FTZ on letrozole-induced experimental PCOS and its associated insulin resistance in mice. Prepubertal female mice in the experimental groups (letrozole and FTZ) received continuous infusion of letrozole (50 μg/day) for 35 days. FTZ was administrated to mice by oral gavage daily at dosage of 2.892 g/kg body weight for 5 weeks. All groups of mice were fed a high-fat diet (HFD). Ovary and adipose tissue were collected from all mice after 5 weeks and adiponectin, testosterone, estradiol, and luteinizing hormone level determined. Letrozole-induced morphological changes in the ovary, including a decreased number of corpora lutea and antral follicles, and increased cystic follicles, were significantly attenuated in FTZ-treated mice. Additionally, FTZ treatment notably reversed PCOS-related disruption of estrous status. PCOS-related insulin resistance was markedly alleviated. Mechanistically, FTZ treatment notably enhanced circulating level and transcriptional abundance of adiponectin in adipose tissue, thereby orchestrating fat-ovary crosstalk. Our data collectively demonstrate that FTZ exerted preventive benefits in an experimental model of PCOS, at least partially by potentiating the production of adiponectin from adipose tissues. This suggests that FTZ is a promising treatment for PCOS.
