WebFeb 1, 2024 · The Cyst(e)ine/GSH/GPX4 Axis. For many years, the Cyst(e)ine/GSH/GPX4 system was thought to be the only pathway to inhibit ferroptosis. SLC7A11 and solute carrier family 3, member 2 (SLC3A2) on the cell membrane constitute system XC-, which imports the cystine into cells with a 1:1 counter-transport of glutamate. Cystine is rapidly … WebDescription Glutathione peroxidase 4 (GPX4) utilizes glutathione (GSH) to detoxify lipid peroxidation and plays an essential role in inhibiting ferroptosis. As a selenoprotein, GPX4 protein synthesis is highly inefficient and energetically costly. How cells coordinate GPX4 synthesis with nutrient availability remains unclear.

WebJan 25, 2024 · As GPX4 is the major PLOOH-neutralizing enzyme, a general mechanism underlying erastin/RSL3-induced ferroptosis emerged: both compounds inactivate GPX4 – RSL3 does so directly, and erastin does so indirectly by inhibiting cystine import, thus depriving cells of cysteine, an essential cellular antioxidant and a building block of GSH.
WebFeb 3, 2024 · 2.3 Xc-GSH-GPX4 pathway. In mammals, the cyst(e)ine-GSH-GPX4 signaling axis has been identified as the primary regulatory system for ferroptosis. ROS are the byproducts of aerobic metabolism, and unrestrained ROS production significantly contributes to cellular ferroptosis (Sun et al., 2024).
