Luo et al. found that cardiac microvascular endothelial cells isolated from T2DM mice exhibited increased expression of pro-ferroptotic genes (Tfrc, Acsl4, Ptgs2), decreased expression of anti-ferroptotic genes (Gpx4, Slc7a11), and elevated lipid peroxidation (MDA, 4-HNE), indicating that hyperglycemia also induces ferroptosis in endothelial cells [97]. Here, TFRC is linked to type 2 diabetes mellitus.
