WebFirst, the role of redox homeostasis and lipid metabolism in ferroptosis has been highlighted. The cystine/glutamate antiporter system (system X C −) located in the cell membrane participates in the synthesis of GSH, and GPX4 uses GSH as a substrate to restore lipid peroxides to normal lipids (Cao and Dixon, 2016; Stockwell et al., 2024). WebJun 16, 2024 · SLC7A11/GPX4 pathway functions as the canonical defense against ferroptosis by assisting intracellular glutathione (GSH) synthesis and alleviating lipid peroxidation . SLC7A11 (also known as Xct) is a multipass transmembrane protein which mediates the export of intracellular glutamate and import of extracellular cystine at a 1 : 1 …
WebThe transcription factor Nrf2 can upregulate both GSH and GPX4 levels, effectively preventing ferroptosis [133, 134]. In addition, selenium is an essential micronutrient for GPX4 synthesis by ...
