enzyme glutathione peroxidase 1 GPX1 and Its Dichotomous Roles in Cancer The glutathione peroxidase family: Discoveries

There are several different versions of GPx, each adapted to a different cellular compartment or tissue context GPx1 in the cytosol, GPx2 in the gastrointestinal tract, GPx3 in plasma, GPx4 in membranes

These variants affect how efficiently your cells handle oxidative stress, which may determine whether supplemental glutathione provides measurable benefit

Similarly, cysteine (a key GSH precursor) drives hypoxia adaptation and carboplatin resistance in ovarian cancer 19
