Conclusion
ZZG can improve glucose-lipid metabolism disorder in rats with metabolic syndrome. The reported results provide experimental evidence for ZZG in the treatment of MS.
Methods
Network pharmacology combined with a pharmacodynamic experiment was used to elucidate the therapeutic mechanism of ZZG in MS. Serum samples were collected from rats with MS, induced by a high-sugar-fat-salt diet (HSFSD) combined with streptozotocin (STZ), to measure the levels of biochemical markers. The glucose (GLU), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were detected. The liver tissue of rats was used for histological examination and Western blot analysis.
Objective
To explore the mechanism of the traditional Chinese medicine (TCM), Zhizhu granule (ZZG), in treating metabolic syndrome (MS) based on network pharmacology and pharmacodynamic experiment. Materials and
Results
Network pharmacology analysis generated 69 drug-disease common targets and 10 hub genes closely related to ZZG against MS. KEGG pathway analysis revealed that the PI3K/AKT signaling pathway was the most potential pathway, which took part in the therapeutic mechanisms. In the animal experiments section, the therapeutic effect of ZZG on MS and the therapeutic pathway of ZZG on MS were verified. ZZG could significantly decrease the body weight, TC, TG, LDL-C and GLU levels in MS rats (all p<0.01), alleviate hepatocyte steatosis and decrease liver lipid droplet deposition. Western blot analysis indicated that compared with the model group, the expression levels of PI3K, AKT, and IRS-1 protein were significantly increased (all p<0.05), and the FOXO-1 was significantly decreased (all p<0.05) in the ZZG group.
