WebApr 11, 2024 · Ferroptosis is a mode of cell death regulated by iron-dependent lipid peroxidation. Growing evidence suggests ferroptosis induction as a novel anti-cancer modality that could potentially overcome therapy resistance in cancers. The molecular mechanisms involved in the regulation of ferroptosis are complex and highly dependent … 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.
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 … WebThe cyst(e)ine-glutathione-GPX4 axis regulates ferroptosis. The cystine/glutamate antiporter, system Xc − , is composed of two subunits, SLC7A11 and SLC3A2.
WebThe importance of the GPX4/GSH detoxification mechanism in preventing ferroptosis is demonstrated by the fact that genetic deletion or pharmacological inhibition of GPX4 as well as ... excess of glutamate); (ii) by inhibiting glutamate cysteine ligase, e.g., with BSO; or (iii) by enzymatically degrading cyst(e)ine, carried out by ...
