ABCB11 and alcoholic liver cirrhosis: We also demonstrated that: (i) some periportal hepatocytes (positive for HNF4α) de novo express the biliary markers, CFTR and AE2, in liver sections from patients with alcoholic cirrhosis; and (ii) a subset of cholangiocytes de novo express BSEP in liver sections from EtOH-fed WT mice and patients with alcoholic cirrhosis (Fig. 5A–B).
