sRAGE plays a role as a protective factor in the development of PCOS by inhibiting inflammation.

This study determined the effect of exogenous soluble receptor for advanced glycation end products (sRAGE) on the pro-inflammatory activities that occur during polycystic ovary syndrome (PCOS) in human follicular cells and explored a potential mechanism for preventing the development of inflammation. Follicular fluid was allocated into one of three treatment groups (0, 0.6, and 1.2 μg mL-1 of sRAGE). Collectively, these results indicate that exogenous sRAGE supplementation alleviates inflammation in ovarian follicular granulosa cells by regulating p-ERK and AP-1 signaling.
