does lysosomes contain cysteine homocysteine and glutathione Lysosomal cystine governs ferroptosis sensitivity in cancer via stress response The transsulfuration pathway from homocysteine

The transsulfuration pathway from homocysteine to glutathione (see text). Download Scientific Diagram 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.
