Core Tip

Core tip: We constructed a liver fibrosis rat model with carbon tetrachloride (CCl4). The Sprague-Dawley rats were randomly divided into four groups: control group, morin group, CCl4 group, and morin + CCl4 group. α-SMA, collagen I, collagen III, NF-E2-related factor 2 (Nrf2), heme oxygenase (HO-1), and quinone oxidoreductase 1 (NQO1) were analyzed by real-time PCR and Western blot methods using frozen liver specimens. We found that morin could reduce hepatic fibrosis by inducing the expression of Nrf2 and its downstream antioxidant factors in the CCl4-induced rat liver fibrosis model.
