Mechanism study of Sijunzi Decoction intervening colorectal cancer based on network pharmacology / 国际中医中药杂志

ABSTRACT

Objective:Based on the network pharmacology, this study preliminarily aims to explore the mechanism of Sijunzi Decoction in the intervention of colorectal cancer. Methods:The active components and targets of Sijunzi Decoction were gained by Traditional Chinese Medicine Pharmacology Database Systems (TCMSP); and the targets were standardized with the help of Uniprot database. The related targets of colorectal cancer were obtained by GeneCards database and Disgenet database, and the intersection targets of berbal medicine and diseases were screened by R language. The visual regulation network of "active ingredient-disease target" of Sijunzi Decoction was constructed by Cytoscape software, and the protein interaction network was constructed by STRING database. The functional enrichment analysis of gene ontology (GO) and the pathway enrichment analysis of Kyoto Encyclopedia of Gene and Genome (KEGG) were carried out by Bioconductor platform. Results:A total of 135 active components and 68 intersection targets of Sijunzi Decoction were obtained. The core target proteins included IL6, VEGFA, CASP3, EGFR and so on. GO functional enrichment analysis involved 91 items, which mainly affected transcription factor activity, enzyme activity, receptor activity and biochemical process regulation. KEGG pathway enrichment analysis contained 126 items, concerning infection, cancer, apoptosis, inflammation and other pathways. Conclusion:The active components of Sijunzi Decoction mainly regulate biological processes such as transcription factor activity and enzyme activity of colorectal cancer cells through cancer signal pathway and inflammatory signal pathway, so as to play a role of interventing of colorectal cancer.
