Potent Upregulation of Glutathione and NAD(P)H:Quinone Oxidoreductase 1 by Alpha-lipoic Acid in Human Neuroblastoma SH-SY5Y Cells: Protection Against Neurotoxicant-elicited Cytotoxicity

Alpha-lipoic acid (LA) has recently been reported to afford protective effects in neurodegenerative disorders. However, the mechanisms underlying LA-mediated neuroprotection remain to be investigated. This study was undertaken to determine whether LA treatment could increase endogenous antioxidants and phase 2 enzymes in cultured human neuroblastoma SH-SY5Y cells, and whether such increased cellular defenses could afford protection against...
