Abstract:

To study the effects of flavonoids from Rosa davurica Pall. on glucose metabolism and key enzyme activities in insulin-resistant HepG(IR-HepG2) cells, the HepG2 cells were induced by high concentration of insulin to established IR-HepG2 cell model. The cells were treated with R. davurica flavonoid for 24 h. The cell activity was detected by MTT method, and the effect of the glucose consumption treated by R. davurica flavonoid was evaluated. The intracellular glycogen accumulation levels and IR-HEPG2 cell key enzymes hexokinase(HK), pyruvate kinase(PK), glucose-6-phosphatase(G6Pase), phosphoenol acetate carboxylase(PEPCK) activities were determined. The results showed that IR-HepG2 cell model was successfully established by treating HepG2 cells with 0.1 μmol/L insulin for 24 h. The glucose consumption rate of cells in the 0.10-1.00 g/L R. davurica flavonoid treatment group was all more than 18%, and the cell activity was best after cultured for 24 h. Compared with the model group, the 1.00 g/L R. davurica flavonoid treatment group increased the glycogen content by 81.45%(P < 0.05), HK and PK viability increased by 29.26%(P < 0.05) and 31.93%(P < 0.05), and the activities of PEPCK and G6Pase decreased by 30.82%(P < 0.05) and 7.32%(P < 0.05), respectively. R. davurica flavonoids were potential bioactive compounds that could regulate carbohydrate metabolism by modulating key enzymes in IR-HepG2 cells warrants in-depth study.
