Oxidative damage and lipid peroxidation is recovered by treatment with MQ-EO through the upregulation of glutathione (GSH) levels or anti-oxidants, such as superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT), in α-MSH-stimulated B16 melanoma [179]. This evidence concerns the gene SOD1 and melanoma.
