WebJun 21, 2024 · GPX4 is a unique subtype of GPXs, acting as a phospholipid hydro-peroxidase to reduce lipid peroxides to lipid alcohols. The endogenous redox cycle maintained by GSH and GPX4 is essential to defend lipid peroxidation ( Lu, 2009; Brigelius-Flohé and Maiorino, 2013; Lu, 2013; Forcina and Dixon, 2024 ). WebJul 1, 2024 · Thus, GPx4, GSH, and α-tocopherol are integrated in a concerted anti-peroxidant mechanism. Recent Advances: Ferroptosis has been recently identified as a cell death subroutine that is specifically activated by missing GPx4 activity and inhibited by iron chelation or α-tocopherol supplementation.

Of note, the active site of GPx4 contains the rare amino acid selenocysteine (Sec), which is encoded by the UGA codon ( 15 ). Each form of GPx4 plays protective roles within each organelle, and their dysregulation is associated with disease ( 12, 16 – 21 ).
WebOnce GPX4 is activated, GSH can reduce toxic lipid hydroperoxides (L-OOH) to non-toxic lipid alcohols (L-OH), 28 indicating that GSH is a significant protective metabolite that prevents ferroptosis.
