Anti-colorectal Cancer Molecular Mechanism of Astragali Radix and Curcumae Rhizoma Based on Network Pharmacology / 中国实验方剂学杂志

ABSTRACT

Objective:The network pharmacology method was used to predict targets and signaling pathways of the drug pair Astragali Radix and Curcumae Rhizoma in treating colorectal cancer,in order to analyze the effective material basis and action mechanism. Method:Disease targets for colorectal cancer were collected through Therapetutic Target Database(TTD)and Drugbank database. Components of Astragali Radix and Curcumae Rhizoma were obtained from the Traditional Chinese Medicine Systems Pharmacology Database, and the Analysis Platform (TCMSP). ChemMapper and PharmMapper database were used to predict the disease targets of effective components. The "compound-disease targets" network model was established by Cytoscape software. The function analysis of gene ontology(GO)and the enrichment analysis of Kyoto encyclopedia of genes and genomes(KEGG)were carried out with ClueGO plug-in. Result:The network contained 56 compounds and 54 targets. The crucial targets included 5'-AMP-activated protein kinase catalytic subunit alpha1(PRKAA1), prostaglandin G/H synthase 1(PTGS1), prostaglandin G/H synthase 2(PTGS2), Thymidylate synthase(TYMS), Carboxylesterase 1(CES1), vascular endothelial growth factor B(VEGFB), vascular endothelial growth factor A(VEGFA), glutathione S-transferase P(GSTP1), and serine hydroxymethyltransferase 1(glyA). Function about target genes inclined to peptide-tyrosine phosphorylation, extracellular regulated protein kinase(ERK)1 and ERK2 signal series, negative regulation of endothelial cell apoptosis process, et al. Important KEGG Pathways involved pathways in cancer, Ras signaling pathways, Rap1 signaling pathways, and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathways. Conclusion:The anti-colorectal cancer activities of Astragali Radix and Curcumae Rhizoma were mainly affected by inhibiting cell proliferation and differentiation, promoting tumor cell apoptosis, resisting tumor angiogenesis, and enhancing immunity as phenotype intervention mode in network. The active signaling pathway is most related to Ras signaling pathway, Rap1 signaling pathway and PI3K/Akt signaling pathway.
