Glutathione in cancer cells
WebGlutathione peroxidase exists in at least five isoforms in the human body, GPX1-5 . Of these five types, GPX4 protects cells against membrane peroxidation and cell death by catalyzing the reduction of hydrogen peroxide and lipid peroxides at the expense of reduced glutathione, thus protecting cells from oxidative stress [5,6]. The gene for GPX4 ... WebGlutathione (L-γ-glutamyl-L-cysteinyl-glycine; GSH) in cancer cells is particularly relevant in the regulation of carcinogenic mechanisms; sensitivity against cytotoxic drugs, ionizing radiations, and some cytokines; DNA synthesis; and cell proliferation and death. The intracellular thiol redox state (controlled by GSH) is one of the endogenous effectors …
