Provided is the use of an ECM1 gene-knockout mouse in the screening of an anti-hepatic fibrosis drug. Specifically, provided is a method for preparing an animal model of hepatic fibrosis or related diseases thereof in non-human mammals, which method comprises the following steps: (a) providing a non-human mammalian cell and inactivating an ECM1 gene in the cell, thereby obtaining a non-human mammalian cell in which the ECM1 gene is inactivated; and (b) using the cell in which the ECM1 gene is inactivated obtained in step (a) to prepare an animal model of hepatic fibrosis or related diseases thereof in which the ECM1 gene is inactivated. The animal model is an effective animal model of hepatic fibrosis or related diseases thereof, may be used for studying hepatic fibrosis or related diseases thereof, and may be used in the screening and testing of a particular drug. |
