Pharmacological Mechanism of Xiao Xianxiongtang in Treatment of Type 2 Diabetes Mellitus Based on Network Pharmacology / 中国实验方剂学杂志

ABSTRACT

Objective:To explore the pharmacological mechanism of Xiao Xianxiongtang in treating type 2 diabetes mellitus (T2DM) by network pharmacology. Method:The main active ingredients, corresponding targets and target genes of Xiao Xianxiongtang were searched on Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) website. Relevant target genes of T2DM were obtained through Gene Cards. The targets of drug active ingredients were mapped to the targets of T2DM, and the intersection targets were obtained as the predictive targets of Xiao Xianxiongtang on T2DM. Cytoscape 3.7.1 software was used to construct the drug active ingredient-intersection target network model and select the key active ingredients. Interactive protein-protein interaction network (PPI) was constructed by STRING website, and key target genes were selected. Gene function analysis (GO) and enrichment analysis based on the Kyoto encyclopedia of genes and genomes (KEGG) pathway were performed on the intersecting targets using DAVID6.8 online tool. Result:Xiao Xianxiongtang had 30 active ingredients, 156 relevant targets, 14 key active ingredients and 18 key target genes on T2DM. GO analysis showed that the biological functions of Xiao Xianxiongtang in the treatment of potential genes of T2DM mainly involved transcriptional regulation, oxidative stress, protein binding and inflammatory reaction. KEGG pathway enrichment showed that the main pathways of Xiao Xianxiongtang in the treatment of T2DM were hypoxia inducible factor-1 (HIF-1) signaling pathway, tumor necrosis factor (TNF) signaling pathway, Toll-like receptor signaling pathway and thyroid hormone signaling pathway, phosphatidylinositol 3 kinase/protein kinase B (PI3K/Akt) signaling pathway, hepatitis B, hepatitis C, tyrosine kinase receptor2(ErbB) signaling pathway, calcium signaling pathway and nuclear factor-kappa B (NF-κB) signaling pathway. Conclusion: Xiao Xianxiongtang is a multi-component, multi-target and multi-pathway process in the treatment of T2DM. It plays an important role in the treatment of T2DM by regulating transcription, oxidative stress, protein binding and inflammatory reaction. Conclusion:The mechanism of Xiao Xianxiongtang in treating T2DM may alleviate insulin resistance, increase insulin sensitivity and reduce blood sugar by inhibiting the secretion of inflammatory factors, participating in anti-inflammatory response, reducing oxidative stress, increasing intracellular calcium concentration, blocking glucagon signaling pathway and activating PI3K/Akt pathway.
