Representative agarose gel electrophoresis of RT PCR products for the expression of SNAT3, ASCT2, SNAT1 mRNA (A). Expression of mRNA for SNAT3, ASCT2 and SNAT1 after treatment with MeHg (1 μM, 5 μM, 10 μM). Results are mean ± SD of three independent isolations.*<0.05 vs. control (Mann -Whitney test) (B). Inset: GAPDH expression.
