ABSTRACT
Objective: To research the effects of total flavonoids of Livistona chinensis (TFFL) on normal liver LO2 cells induced by acetaminophen (APAP), and study the liver protective mechanism on liver injury induced by acetaminophen in vitro. Methods: The effects of TFFL on LO2 cells and cell activity induced by acetaminophen were determined by MTT method; The apoptosis rate of LO2 cells induced by APAP was researched by Flow Cytometry combine with staining agent Hoechst 33342; The levels of malondialdehyde (MDA), aspartate aminotransferase (AST), reduced glutathione (GSH), and superoxide dismutase (SOD) were examined; The expressions of iNOS and nitrotyrosine tubulin (NT) in APAP-induced LO2 hepatocyte injury cells was studied by Western blotting method. Results: TFFL had no toxicity to LO2 cells at a given concentration which can promote the proliferation. At the same time, experiment results showed that TFFL prophylactically reduced the apoptosis of LO2 cells induced by APAP. TFFL decreased the level of AST and MDA, increase the level of GSH and SOD, and inhibit the expressions of iNOS protein and NT protein. Conclusion: TFFL has a protective effect on LO2 cells injury induced by APAP. The possible protective mechanism of TFFL is related to the inhibition of oxidative stress and the nitro stress.
