BACKGROUND AND AIM: Traditional Chinese medicine Yinchenhao Tang (YCHT) demonstrated benefits when treating nonalcoholic fatty liver disease (NAFLD), but the dose effects and potential targets are still ambiguous. In this study, different concentrations of YCHT were employed to treat NAFLD and the underlying therapeutic targets were investigated.
EXPERIMENTAL PROCEDURE: Kunming mice were fed with high fat diet (HFD) for 8 weeks to induce NAFLD, then treated with 3 different concentrations of YCHT. Hepatic pathological changes and serum lipid levels were examined. Network pharmacology was applied to screen the potential targets of YCHT for NAFLD modulation. NR1H4 and APOA1 expression was evaluated by QPCR and western blotting. Immunohistochemistry (IHC) staining was conducted to visualize the localization pattern of NR1H4 and APOA1 in the liver.
RESULTS: YCHT significantly reduced liver lipid storage and improved the liver pathological status of NAFLD mice. The serum lipid levels, as well as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, were remarkably reduced by the middle and high dose YCHT. There are 35 potential targets for YCHT to regulate NAFLD. HFD suppressed both RNA and protein expression of NR1H4 and APOA1, while YCHT elevated NR1H4 and APOA1 expression. IHC staining indicated that NR1H4 was mainly located in the cell nucleus and the APOA1 signal was observed at the liver sinusoid or cytoplasm.
CONCLUSION: YCHT can effectively ameliorate HFD induced NAFLD by modulating the promising targets of NR1H4 and APOA1.
