does glutathione peroxidase have iron Mechanism of ferroptosis, 4 (GPX4) glutathione Ferroptosis in Toxicology: Present and

Ferroptosis in Toxicology: Present and Future Oxytosis Ferroptosis in Neurodegeneration: the Underlying Role of Master Regulator Glutathione Peroxidase 4 (GPX4) Molecular Neurobiology Springer Nature Link Ferroptosis regulation in lysosome Lysosomal iron and cathepsin B contribute to ferroptotic cell death. Lysosomal cyst(e)ine can be mobilized to maintain glutathione synthesis and glutathione peroxidase 4 activity, thereby limiting lipid peroxidation. The glutathione peroxidase Gpx4 prevents lipid peroxidation and ferroptosis to sustain Treg cell activation and suppression of antitumor immunity ScienceDirect
