[Abstract]
Objective To investigate the mechanism of Astragali Radix in treatment of metabolic associated fatty liver disease (MAFLD) by means of network pharmacology. Methods According to TCMSP database, GeneCards database, and Comparative Toxicogenomics database, predict and screen the active ingredients of Astragali Radix and related genes of MAFLD, obtain the potential targets of Astragali Radix for treating MAFLD. Cytoscape 3.8.0 software and STRING database was used to construct a component-target network between active ingredients and potential targets. Analyze the network to obtain important targets, and use Metascape database to annotate important targets with gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results Astragali Radix contains 20 active components such as quercetin, kaempferol, isorhamnetin and folic acid, which can act on 91 MAFLD targets. Among them, 27 targets are key targets, such as IL4, EGFR, MAPK8, TNF and HIF-1α, which can regulate AGE-RAGE signaling pathway in diabetic complications, IL-17 signaling pathway, fluid shear stress and atherosclerosis, involved lipid metabolism, oxidative stress and inflammatory response and other biological processes. Conclusion Astragali Radix play a role in treatment of MAFLD through multiple targets and pathways.
