Relative mRNA expression of Abcb1 and Abcg2 in the mPFC following voluntary ethanol consumption and repeated cocaine exposure (mean ± SEM). a One-way ANOVA followed by the Newman-Keuls multiple comparisons test revealed a significant decrease in relative mRNA expression of Abcb1 in the mPFC. b One-way ANOVA followed by the Newman-Keuls multiple comparisons test revealed a significant decrease in relative mRNA expression of Abcg2 in the mPFC. (*p < 0.05, **p < 0.01), (n = 5 for each group)
