Abstract: Objective To explore the interventional effect and mechanism of berberine (BBR) on hepatic lipid accumulation in mice with non-alcoholic fatty liver disease (NAFLD) induced by a high-fat diet (HFD). Methods Twenty-one male wild-type C57BL/6J mice were randomly divided into an HFD group, an HFD+BBR group, and a normal control group. The HFD+BBR group received oral BBR intervention at a dose of 200 mg/(kg·d) for 12 weeks. Body weight, liver weight, and serum triglyceride levels were compared among the groups, and histopathological analysis, lipidomics, gut microbiome analysis, and fecal metabolomics analysis were performed. Results BBR significantly ameliorated hepatic steatosis in mice: the HFD+BBR group showed an 8.42% reduction in body weight (P<0.01), a 10.33% decrease in liver weight (P=0.027), a 39.5% decline in serum triglyceride levels (P<0.001), as well as marked reductions in hepatic lipid droplets and NAFLD Activity Score (P=0.03). Lipidomic analysis confirmed that BBR inhibited the accumulation of diacylglycerol (P=0.004) and triglyceride (P=0.01), restored phospholipid homeostasis, and reduced total hepatic lipids by 13.9% (P<0.05). Gut microbiome analysis revealed that BBR reshaped the gut microbial community structure (P=0.002), with a significant increase in the abundance of Bacteroides (P<0.001). Fecal metabolomic analysis demonstrated that BBR increased agmatine levels (P=0.05), and agmatine was strongly positively correlated with Bacteroides (r=0.681, P=0.001) while negatively correlated with hepatic neutral lipids. Conclusion BBR ameliorates HFD-induced hepatic steatosis by regulating the gut microbiome to promote agmatine production and bidirectionally modulating hepatic lipid metabolism, revealing that the microbiome-metabolite-host axis may serve as a key mechanism underlying the therapeutic effects of BBR in NAFLD.
