Abstract
We report partially redundant function of catenins at AJ in regulating TJ and contributing to the blood-biliary barrier. Furthermore, concomitant hepatic loss of β- and γ-catenin disrupts structural and functional integrity of AJ and TJ via transcriptional and posttranslational mechanisms. Mice with dual catenin loss develop progressive intrahepatic cholestasis, providing a unique model to study diseases such as PFIC. (Hepatology 2018;67:2320-2337).
