[Application of Mdr2 gene knockout mice in liver disease research].

Mdr2 knockout mice is a liver disease model, which causes cholestasis due to the lack of phospholipids in the bile. At present, it is not only used for the study of human homologous MDR3 gene, but also widely used as an animal model of liver diseases such as primary sclerosing cholangitis, liver fibrosis, progressive familial intrahepatic cholestasis, liver cancer. Herein, we review the Mdr2 knockout mice physiological characteristics and its application in liver disease research.
