CGAS and polycystic ovary syndrome: Iron‐dependent lipid peroxidation is not solely caused by the reduction of cellular antioxidant capacity but is also induced by ferritin degradation.[24] The cGAS‐STING pathway serves as a critical regulator of autophagy and ferroptosis.[36] We further observed that PCOS mice exhibited elevated expression levels of the cGAS‐STING pathway, which were suppressed by NMN and 3‐HAA.
