Abstract:

The purpose of this study is to prove the lipid-regulating effects of neohesperidin (NHP) and explore the potential mechanisms related to fibroblast growth factor 21 (FGF21) and AMP-activated protein kinase (AMPK). Free fatty acids (FFAs)-induced lipid-accumulated HepG2 cells, acutely egg yolk-induced dyslipidemia and chronically diet-induced obese (DIO) model mice were treated with NHP. Biochemical analyses were carried out to determine the lipid profiles. Western blotting and real-time PCR were employed to analyze FGF21, AMPK and the related proteins or mRNA expressions. Body weight and food intake were measured in DIO mice. siRNA or inhibitors of FGF21 or AMPK were utilized in further study. NHP showed potent hypolipidemic effect in HepG2 cells loaded with FFAs and reversed the pathological changes of lipid in the acute or chronic dyslipidemia mouse model. It obviously improved the lipid profiles in plasma, liver and gastrocnemius muscles in DIO mice, and led to a significant body weight loss. Simultaneously, FGF21 protein expression or secretion, and AMPK/sirtuin type 1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α) axis or related molecules, was improved by NHP in HepG2 cells and/or DIO mice. Furthermore, the siRNA or inhibitor targeting FGF21 or AMPK rejected the triglyceride-lowering effect of NHP. In conclusion, NHP regulates lipid metabolism in vivo and in vitro via FGF21 and AMPK/SIRT1/PGC-1αsignaling axis.
