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 ). WebApr 12, 2024 · GPX4 converts GSH into oxidized glutathione (GSSG) and reduces LPO and cell damage. 29 Given that reduced GSH levels can trigger ferroptosis, 30 we measured GSH and GSH/GSSG ratio in zebrafish head after hypoxia. The GSH and GSH/GSSG ratio are significantly decreased in hypoxic group, which is rescued by pretreating the …

WebJan 10, 2024 · Strikingly, the glutathione peroxidase 4 (GPX4)-glutathione (GSH) pathway is the most important antioxidant pathway, mainly involving system X c−, cysteine, glutamate, GPX4, and GSH. WebSep 2, 2024 · GPX4 functions downstream of GSH to repair lipid peroxidation. GPX4 is a selenoprotein that functions on biological membranes as a phospholipid hydroperoxidase. It catalyzes the reduction of lipid peroxides at the expense of reduced glutathione. When GPX4 activity is hindered, lipid peroxides accumulate and ultimately cause cell death.
