Effect of dexamethasone (100 nM) on mRNA expression of NTCP and BSEP. (A) mRNA expression in cells following 17 h in culture, n = 3 livers (HF133, HF134, VF1). (B) mRNA expression in cells following 72 h in culture, n = 3 livers (HF133, HF134, VF1). (C) mRNA expression in cells following 96 h in culture, n = 5 livers (HH1571, HH1591, HF79, HF82, HF83). Data represents means ± SEM, *p ≤ 0.05, **p ≤ 0.01.
