Gantangyi Recipe improving abnormal glucose metabolism of hepatocyte peroxidative damage in vitro
Objective,2,To investigate the mechanism of Gantangyi Recipe in ameliorating oxidative stress and regulating (GSK-3β/FoxO1) glycogen synthesis signaling pathway to regulate glucose metabolism.,Methods,2,The hepatocytes were incubated with 500 μmol/L H,2,O,2, for 30 min and then divided into the model group, Gantangyi Recipe group, and metformin group. Gantangyi Recipe group and metformin group were respectively incubated with Gantangyi Recipe (200 μg/L) or metformin (5 mmol/L) for 48 h. The normal group was set up. The cell viability was detected by the CCK-8 method; supernatant glutathione aminotransferase (ALT), glutathione aminotransferase (AST) activity, and malondialdehyde (MDA) content were detected by enzyme-linked immunosorbent assay (ELISA); reactive oxygen species (ROS) levels were detected by DCFH-DA fluorescent probe method; glycogen content was stained by PAS staining method; cell supernatant glucose concentration in hepatocytes was detected by glucose oxidation enzyme method; and cell p-GSK-3β/GSK-3β and p-FoxO1/FoxO1 protein expressions were analyzed by Western blot.,Results,2,Compared with the condition of normal group, H,2,O,2, could induce cell peroxidative damage model, the ALT, AST activity, and MDA content were significantly higher in the model group (,P,<,0.05), ROS generation rate was significantly higher (,P,<,0.05), there was a significant increase in supernatant glucose content (,P,<,0.05), the glycogen staining results showed significant reduction and lighter coloration of cell positive staining granules, and p-GSK-3β/GSK-3β and p-FoxO1/FoxO1 protein expressions were significantly reduced (,P,<,0.05). Compared with the condition of model group, the levels of ALT, AST and MDA were reduced to different degrees after the intervention of Gantangyi Recipe and metformin, the rate of ROS production was significantly reduced (,P,<,0.05), and the effect of Gantangyi Recipe was superior to that of metformin (,P,<,0.05). In the Gantangyi Recipe group, cells stained darker in glycogen staining than those in the model group, the supernatant glucose concentration decreased significantly (,P,<,0.05), and the p-GSK-3β/GSK-3β and p-FoxO1/FoxO1 protein expressions increased (,P,<,0.05).,Conclusion,2,Gantangyi Recipe can alleviate the oxidative stress injury and abnormal glucose metabolism in hepatocytes induced by H,2,O,2,, and the mechanism is related to the activation of the GSK-3β/FoxO1 glycogen synthesis signaling pathway.
