WebMar 1, 2024 · GPX4 is the only peroxidase that can reduce lipid peroxides, and its activity is regulated by the intracellular GSH level. System Xc − imports cystine for the production of cysteine and GSH, and thus plays a crucial role in the regulation of GPX4 activity. FSP1, on the other hand, may reduce CoQ 10 for the suppression of lipid peroxidation ... WebMar 17, 2024 · There are four main signalling pathways that mediate lipid peroxidative scavenging, including GPX4-GSH, FSP1-CoQH2, GCH1-BH4 and DHODH-CoQH2. GPX4 is the only enzyme in the GPX family that specifically removes lipid peroxidation. Its activity depends on the level of GSH.
