Abstract

Isorhamnetin treatment significantly reduced serum levels of glucose, insulin, testosterone, and luteinizing hormone in DHEA-induced PCOS rats.

  • DHEA-induced PCOS in rats resulted in increased levels of serum glucose, insulin, testosterone, and luteinizing hormone, while estradiol, sex hormone-binding globulin, and follicle stimulating hormone levels were decreased.
  • The treatment led to increased body weight, ovary weight, and ovary volume, along with the presence of cystic follicles and a decrease in corpus luteum.
  • Inflammatory levels and apoptosis in ovary tissues were higher in DHEA-induced PCOS rats, with activation of the tumor necrosis factor (TNF) signaling pathway.
  • Isorhamnetin treatment decreased inflammatory factors and inhibited apoptosis in the ovary tissues of PCOS rats.
  • After isorhamnetin treatment, levels of TNF receptor superfamily member 1 A, TNF-α, and FAS in ovary tissues were significantly reduced.
