Chandley et al. investigated the expression of five antioxidant-related genes in oligodendrocytes captured from MDD suicide patients: superoxide dismutase-1 (SOD1), superoxide dismutase-2 (SOD2), glutathione peroxidase-1 (GPX1), catalase (CAT), and alkylglycerone phosphate synthase (AGPS). The gene discussed is SOD1; the disease is major depressive disorder.
