Methamphetamine (METH)-induced alterations in the expression of p53 and bcl-2 protein were studied in the striatum of wild type, neuronal nitric oxide synthase knockout (nNOS -/-) and copper zinc superoxide dismutase overexpressed (SOD-Tg) mice. METH treatment up-regulated p53 and down-regulated bcl-2 expression in the striatum of wild type mice. No significant alterations were observed in the expression of these proteins in the nNOS -/- or SOD-Tg mice. These data suggest that METH might cause its neurotoxic effects via the production of free radicals and secondary perturbations in the expression of genes known to be involved in apoptosis and cell death machinery.
