Ntcp, Oatp1a4, Bsep, and Mrp3 protein abundance in livers of mice 24 h following BDL. Western blots for Ntcp, Oatp1a4, Bsep, and Mrp3 were performed with use of liver membrane protein fraction (40 μg protein/lane) from sham-operated and BDL mice. β-Actin blot was used as a protein loading control for each transporter. Bars represent the relative Ntcp, Oatp1a4, Bsep, and Mrp3 protein amounts ± SE of three mice. The scales for mean relative protein expression differ for each transport protein. *Statistical difference (p < 0.05) from the respective values of sham-operated mice.
