Hepatic transcriptome discloses the potential targets of Xuefu Zhuyu Decoction ameliorating non-alcoholic fatty liver disease induced by high-fat diet.

Xuefu Zhuyu decoction (XZD), a traditional Chinese medicinal formula, was firstly recorded in the Qing dynasty of ancient China and previously demonstrated to ameliorate hepatic steatosis. In the present study, the effects of XZD on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD) were evaluated in mice and the hepatic transcriptome was detected to disclose the potential mechanisms of XZD. The effects of XZD (low- and high-dosage) on NAFLD induced by HFD for 16 weeks were evaluated. Obeticholic acid was used as control drug. Body weight, food intake and index of homeostatic model assessment for insulin resistance (HOMA-IR) were analyzed. Hepatic histology were observed in haematoxylin and eosin stained sections and quantified with NAFLD activity score (NAS). Lipid in hepatocytes was visualized by Oil red staining. Alanine aminotransferase (ALT) and hepatic triglyceride (TG) was measured. The hepatic transcriptom was detected with RNA-sequencing and validated with real-time polymerase chain reaction, western-blotting and hepatic quantitative metabolomics. XZD ameliorated hepatic histology of NAFLD mice, accompanied with decreasing fasting insulin, HOMA-IR, NAS, ALT and hepatic TG. The hepatic transcriptom of NAFLD was significantly reversed by XZD treatment, especially the genes enriched in the pathways of arachidonic acid metabolism, fatty acid degradation, cytokine-cytokine receptor interaction and extracellular matrix (ECM) -receptor interaction. The hepatic quantitative metabolomics analysis confirmed fatty acid degradation as the key targeting pathway of XZD. XZD ameliorated NAFLD induced by HFD, which probably correlated closely to the pathways of fatty acid degradation. © 2023 Center for Food and Biomolecules, National Taiwan University.
