The purpose of this research is to probe into the hepatoprotective activity and the molecular mechanism of taxifolin. Materials and Methods: The liver fibrosis model was established by intraperitoneal injection of 5 mL/kg body weight of CCl4 (20% CCl4 peanut oil solution), and taxifolin was dissolved with 0.9% physiological saline and administered intragastrically to mice. Results: The results indicated that CCl4-induced significantly increased the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in mice. Histopathological examination showed severe hepatocyte necrosis and hepatic tissue lesion. Immunohistochemical staining and rt-PCR analysis demonstrated that the expressions of inducible nitric oxide synthetase (iNOS), cyclooxygenase-2 (COX-2), IL-1β, IL-6, and TNF-α were increased. These changes were significantly reversed when treated with taxifolin. In addition, TUNEL staining and Bcl-2/Bax pathway confirmed that taxifolin significantly inhibited hepatocyte apoptosis. Besides, the research confirmed that taxifolin also inhibited the activation of hepatic stellate cells and the production of extracellular matrix (ECM) by regulating PI3K/AKT/mTOR and TGF-β 1/Smads pathways. Conclusion: Taxifolin inhibited inflammation, and attenuated CCl4-induced oxidative stress and cell apoptosis by regulating PI3K/AKT/mTOR and TGF-β 1/Smads pathways, which might in part contributed to taxifolin anti-hepatic fibrosis, further demonstrating that taxifolin may be an efficient hepatoprotective agent.
