The effects of DNts on mRNA expressions of transporters and metabolic enzymes in the liver of ANIT-induced cholestasis rats. Relative hepatic mRNA levels of (A) basolateral uptake transporters (Oatp1, Ntcp) and basolateral efflux transporters (Mrp3), (B) basolateral efflux transporters (Mrp4, Ostα and Ostβ) (C) canalicular efflux transporters (Mrp2, Mdr2 and Bsep), and (D) bile acid-metabolizing enzymes (Cyp2b1, Ugt1a1 and Sult2a1) were determined by qRT-PCR in liver samples isolated from rats treated with vehicle, DNts, ANIT or DNts + ANIT (n = 3 for each group). Expression was normalized to Gapdh, and each bar represents the mean ± SD of three independent experiments. Significant difference between two groups. *p < 0.05, **p < 0.01 vs. control group; #
p < 0.05, ##
p < 0.01 vs. the ANIT-treated group.
