Phase I and Phase II drug‐metabolizing enzymes are expressed and heterogeneously distributed in the biliary epithelium
Fatima Lakehal, Dominique Wendum, Véronique Barbu, Laurent Becquemont, Raoul Poupon, Pierre Balladur, Laurent Hannoun, François Ballet, Philippe H. Beaune, Chantal Housset – 30 December 2003 – Tissue expression of drug‐metabolizing enzymes influences susceptibility to drugs and carcinogens. Because the biliary epithelium, exposed to bile‐borne chemicals, may give rise to drug‐induced cholangiopathies and to cholangiocarcinomas, we determined the pattern of expression of drug‐metabolizing enzymes in this epithelium.
