ABSTRACT
Introduction and aim. Salidroside and curcumin (SC) formula could alleviate lipid deposition in high fat diet-induced nonalcoholic
fatty liver disease (NAFLD). However, the mechanisms are still unknown, and the magnitude of potential therapeutic benefit remains
understudied.
Material and methods. The rats were treated with high fat diet for 14 weeks to induce NAFLD. The experiment
was divided into control, model (NAFLD), SC formula and rosiglitazone groups (n = 7 in each group). Hematoxylin-eosin (H&E)
staining was applied to detect liver morphological changes. Biochemical, metabolic indices and inflammation factors in liver tissue
and serum were detected. Additionally, the activities of related enzymes were detected by enzyme-linked immunosorbent assay.
Results. In the established rat model, typical lipid deposition and liver steatosis were observed. Liver triglyceride, free fatty acids,
sera alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, fasting insulin, fasting blood glucose and
homeostasis model assessment of insulin resistance were elevated in model group. Liver malondialdehyde was significantly elevated,
while superoxide dismutase was significantly decreased in model group, compared with control. Moreover, tumor necrosis factor-α
and Interleukin-1 were significantly produced in model group, compared with control. As a mechanism, high fat diet decreased tissue
AMP-activated protein kinase (AMPK), phosphorylated AMPK, carnitine palmitoyltransferase 1 and increased inacetyl-CoA carboxylase
(ACCase), phosphorylated ACCase. Importantly, these abnormal changes caused by high fat diet were reduced by SC formula
administration.
Conclusion. SC formula could ameliorate the injury caused by high fat diet. The effect was likely mediated via its
influence on insulin resistance, lipid peroxidation injury and AMPK signaling pathway.
