WebJan 22, 2024 · Genetic-overexpression of GPX4 effectively increased level of GPX4 in the brain, and clearly relieved neuronal dysfunction, brain edema, blood brain barrier (BBB) injury, oxidative stress and inflammation after ICH. Gpx4-catalyzed reduction of lipid hydroperoxides in lipid membranes has been described. WebOct 30, 2013 · Phospholipid hydroperoxide glutathione peroxidase (PHGPx or GPx4; EC1.11.1.12) is a selenoperoxidase that can directly reduce phospholipid and cholesterol hydroperoxides. The mature cytoplasmic GPx4 is a monomeric protein with molecular weight of 19.5 kDa.
