Background: Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder among women and is characterised by chronic low-grade inflammation, ovulatory dysfunction, hyperandrogenism, and often by insulin-resistance. However, little is really known on insulin/IGF signalling in PCOS ovaries. This study aim ed to investigate the amount of Insulin (IR) and IGF-I receptor type I (IGF-IR1) and their intracellular mediators in granulosa cells from PCOS women with r...

Background: PCOS is characterised by chronic low-grade inflammation, ovulatory dysfunction, hyperandrogenism, and insulin-resistance. The IGFsystem includes IGF-I, -II and seven IGFBPs, which regulate IGFbioavailability. Chronic inflammation modifies the IGF system that regulates ovarian function and glucose metabolism. HMGB1 is related with both inflammation and insulin sensitivity;we previously described increased HMGB1 FF in PCOS. This study aim ed to inves...
