Abstract:

In the present study, we investigated the mechanism of action of Danggui Buxue decoction (DBD) in diabetic retinopathy (DR) using network pharmacology and molecular docking combined with experimental validation. GeneCards and DisGeNET were used to collect DR targets. The intersection of the two targets was obtained using Venny 2.1. Cytoscape was used to construct "disease-drug-component-target" and protein-protein interaction (PPI) networks. DAVID database was used to enrich key targets with Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). AutoDockVina was used to perform molecular docking of primary active ingredients with key targets. Molecular docking validation was performed with key targets by AutoDockVina. Finally, the network pharmacological results were validated by animal experiments. A total of 84 common targets of DBD and DR were collected, 220 entries were revealed by GO analysis, and 113 signaling pathways were obtained by KEGG enrichment analysis. Molecular docking results showed that the key targets had suitable docking activities with quercetin, dousterol and other active ingredients. Animal experiments showed that DBD could improve retinal tissue morphology, lower blood glucose, increase insulin secretion, reduce VEGF and TNF-α protein expression levels and increase PI3K and Akt1 expression levels in the retinal tissues of DR rats (P < 0.05, P < 0.01). The treatment of DR by DBD had the characteristics of multiple active ingredients, multiple targets and multiple pathways, which could exert therapeutic effects on DR by regulating the core targets of TNF-α, VEGFA, PI3K, and AKT and affecting the signaling pathways of PI3K/AKT and TNF.
