Abstract

Abstract:

To explore the potential mechanism of Mori Cortex in the treatment of type 2 diabetes mellitus (T2DM) using network pharmacology and molecular docking methods. The active ingredients and predicted targets of Mori Cortex were screened using the traditional Chinese medicine systems pharmacology database and analysis platform. T2DM targets were retrieved from the DrugBank, GeneCards, and TTD databases.Then, the components-target network diagram of Mori Cortex and the protein-protein interaction(PPI)network of intersection targets were constructed. Gene ontology (GO) enrichment analysis and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis were performed. Finally, active ingredients and key targets were selected, and AutoDock software was used for molecular docking.The 25 active ingredients and 126 intersection targets of Mori Cortex and disease were predicted. The PPI network revealed that AKT1, IL-6, TNF, VEGFA, TP53, and CASP3 may be the key targets of Mori Cortex in the treatment of T2DM.The GO enrichment analysis included biological processes such as the cytokine signal transduction pathway, response to lipids, and the apoptosis signal pathway.The KEGG pathway enrichment analysis included the AGE-RAGE, IL-17, TNF, and PI3K-Akt signaling pathways. The results of molecular bonding showed that quercetin, kahenol, β-sitosterol, iristectorigeni B, and glabrone had good binding activities with AKT1, IL-6, VEGFA, and CASP3.The binding energy of quercetin with AKT1 was the lowest and that of glabrone with IL-6, VEGFA and CASP3 was the lowest.This study preliminarily explored the active ingredients, potential targets, biological processes, and signaling pathways of Mori Cortex in the treatment of T2DM, providing a scientific basis for its clinical application.

Key words: Mori Cortex, type 2 diabetes, network pharmacology, molecular docking technology, mechanism
