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. In this process, GPX4 works as a key enzyme and GSH works as a reducing agent to mediate the reduction reaction of lipid peroxide and negatively ... WebAug 21, 2024 · The pathway can be triggered by multiple mechanisms that modulate intracellular glutathione (GSH) pool, labile iron levels, polyunsaturated fatty acids (PUFAs), and the activity of GSH peroxidase 4 (GPX4), a selenoprotein that reduces phospholipid hydroperoxides using GSH and prevents ferroptotic cell death ( 13 – 15 ).
