in vitro experiments demonstrated that SGK1 knockdown attenuated erastin-induced downregulation of Slc7a11, GPX4, GSH, and oxidized glutathione (GSSG), while reducing lipid peroxidation, iron accumulation, and mitochondrial damage upregulation, suggesting SGK1's critical role in CHD-associated ferroptosis (44). Here, GPX4 is linked to coronary artery disorder.
