Identification of the Mechanism of Action of the Index Components of Banxia Xiexin Decoction for Gastric Cancer through Network Pharmacology, Bioinformatics, and Molecular Docking Analysis

Abstract

Banxia Xiexin decoction (BXD) is a traditional prescription widely used to treat gastrointestinal conditions, including gastric cancer. Through network pharmacology, bioinformatics, and molecular docking analysis, this study aimed to investigate the potential mechanism of the antigastric cancer effect of BXD and pave the way for future research. The network pharmacology analysis used BXD index components to improve reliability and validity. Prognosis-related genes identified through Lasso and Cox regression analysis were considered potential BXD core targets for gastric cancer. Functional enrichment analysis was conducted to uncover the potential mechanism of action of BXD in gastric cancer. In addition, molecular docking of the index components of BXD and the core targets was used to validate the results. The present study obtained six index components of BXD and 155 corresponding antigastric cancer targets. ANXA5, CYP19A1, FGF1, and F2 in the prognostic signature model were identified as core targets of the index components of BXD. Protein-protein interaction networks and functional enrichment analysis indicated that proteoglycans in cancer, PI3K-Akt, and other pathways were involved. According to molecular docking results, six index components showed good-to-strong binding affinities to the core targets. The results indicated that the index components of BXD act on multiple pathways and targets of gastric cancer. Our study paved the way for further investigation of the antigastric cancer activity and mechanisms of BXD.
