ABSTRACT
Background: Drug-induced liver injury (DILI) is extremely common in clinical practice and needs to be focused. Anwulignan is a unique lignan monomer of Schisandra Sphenanthera Fructus and is used as the main active ingredient of Wuzhi tablet, which is used for liver protection in clinical practice. In this study, an acute liver injury mouse model induced by acetaminophen and paracetamol (APAP) was used to observe its effects. Materials and Methods: An acute liver injury mouse model was established by intraperitoneally injecting APAP. Mice were divided into blank control (CON) group, APAP model (MOD) group, Anwulignan CON group, and Anwulignan MOD group. Anwulignan (6 mg/kg) or sodium carboxymethylcellulose (10 mL/kg) was intragastrically given to mice once a day, successively for 14 days. On day 14, 250 mg/kg APAP solution (10 mL/kg) or saline was injected intraperitoneally, and 12 h later, the mice were killed. alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in the serum of mice were tested. The liver index of mice was calculated, and the pathology of liver injury was evaluated by HE staining in mice. The activities of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) as well as the content of malondialdehyde (MDA) in the liver tissue were tested. The levels of kelch-like ECH-associated protein 1 (Keap-1), nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), BCL2 associated X protein (Bax), B-cell lymphoma-2 (Bcl-2), caspase-3 and tumor suppressor protein (P53) mRNAs in the liver tissues of mice were detected by reverse transcription-PCR (RT-PCR), and the expression levels of Keap-1, Nrf2, HO-1, Bax, Bcl-2, caspase-3 and P53 proteins in the liver tissue of mice were detected by Western blot. Results: Anwulignan can alleviate the acute liver injury of mice. The down-regulation of the cyclophosphamide (CYP2E1) expression in the liver tissue of mice to reduce the hepatotoxicity of APAP, and the regulation of Nrf2-ARE signaling pathway-related gene expressions to play an antioxidant role and apoptosis-related gene expressions to inhibit the liver cell apoptosis may be involved in the mechanism through which Anwulignan can exert its effect. Conclusion: Anwulignan can alleviate the liver injury induced by APAP in mice, and this study may provide evidence for researching and developing some drugs and nutraceuticals used for preventing and treating liver injury.
