Figure 1. MTT assay showing viability of cells post treatment with varying amounts of METH for 24 h.

**p<0.01, ***p<0.001 (A). (B) Representative western blot confirming up regulation of ATP1A3 in rat striatal neurons treated with indicated concentrations of METH for 24 h as compared to controls. (C) Bar graphs showing significant increase in ATP1A3 expression post METH treatment versus control. Data represented as Mean ± SEM of three independent experiments. *p<0.05.
