- Abstract: BACKGROUND:Total flavonoids from Sophora flavescens have a variety of pharmacological effects,including anti-inflammatory,immunomodulatory,antioxidant,and anti-hepatic injury,but the therapeutic effects and mechanisms in non-alcoholic fatty liver disease are not clear.OBJECTIVE:To reveal the mechanism of total flavonoids from Sophora flavescens in the treatment of non-alcoholic fatty liver disease using bioinformatics,network pharmacology and zebrafish experimental validation.METHODS:A zebrafish model of non-alcoholic fatty liver disease was constructed to observe lipid accumulation,pathomorphologic changes,and expression of inflammatory genes in the liver of zebrafish after treatment with total flavonoids from Sophora flavescens.The active ingredients of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease-related targets were obtained from TCMSP,Swiss Target Prediction,and Bat-man databases.STRING was used to perform protein-protein interaction network analysis,GO functional enrichment and KEGG pathway enrichment analysis.Based on the GSE33814 dataset,the differentially expressed genes of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease intersection targets were screened out.Correlation analysis and receiver operating characteristic curve were performed using R4.3.2 software.Core genes were verified by the validation set GSE89632.RT-qPCR and western blot assays were performed to verify the expression of core pathway-related genes and proteins.RESULTS AND CONCLUSION:(1)Total flavonoids from Sophora flavescens could improve lipid accumulation in the liver of zebrafish with non-alcoholic fatty liver disease,significantly inhibited the elevation of lipid and aminotransferase levels in zebrafish(P<0.05),and regulated the expression of genes related to inflammation and lipid metabolism.(2)A total of 168 common targets were obtained using the network pharmacology,and top 10 core genes,identified by Cytoscape topology analysis,were HSP90AA1,STAT3,PIK3R1,MAPK1,AKT1,RXRA,PIK3CA,EGFR,JAK2,and ESR1.GO and KEGG analysis pathways mainly included insulin resistance,lipids,and atherosclerosis.There were a total of 59 differentially expressed genes after intersection of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease targets.The receiver operating characteristic curve and validation set analyses yielded six core targets that were significantly different between healthy individuals and patients with non-alcoholic fatty liver disease(P<0.01).(3)RT-PCR and western blot results verified that total flavonoids from Sophora flavescens inhibited the activation of the JAK2/STAT3 signaling pathway in zebrafish.To conclude,total flavonoids from Sophora flavescens may alleviate the inflammatory response through the JAK2/STAT3 signaling pathway,thus inhibiting lipid accumulation and improving non-alcoholic fatty liver disease.
