Objective:To explore the key targets and mechanism of Bielong Ruangan decoction in the treatment of liver cancer based on network pharmacology and molecular docking.Methods:Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database, PubChem database and PharmMapper database were used to search and screen the chemical components and related targets of Bielong Ruangan decoction and the targets of liver cancer diseases. The network diagram of " Bielong Ruangan decoction-traditional Chinese medicine-active ingredient-predicted target-disease" was constructed; Protein-protein interaction (PPI) network were analyzed through String database; gene ontology (GO) enrichment analysis was performed through WebGestalt database; Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was carried out through KEGG Orthology Based Annotation System (KOBAS) database; Molecular docking of the active components and core target proteins of Bielong Ruangan decoction was carried out by using PyMOL, Auto DockVina and other software.Results:Bielong Ruangan decoction had 67 active components, 154 liver cancer targets and 244 pathways. According to the analysis of network pharmacology, Bielong Ruangan decoction may play an anti-cancer role through key targets such as epidermal growth factor receptor (EGFR), mitogen activated protein kinase 1 (MAPK1), estrogen receptor 1 (ESR1), MAPK8, serine threonine protein kinase 1 (AKT1), MAPK14, cysteine protease 3 (CASP3), cyclin-dependent kinase 2 (CDK2), bone morphogenetic protein 2 (BMP2), aldose reductase (AKR1B1) and other key targets. KEGG enrichment analysis showed that the treatment of liver cancer by Bielong Ruangan decoction involved the regulation of vascular endothelial growth factor (VEGF) signaling pathway, tumor necrosis factor (TNF) signaling pathway, thyroid hormone signaling pathway, T cell receptor signaling pathway and other pathways. The results of molecular docking showed that the binding energy of all compounds to protein was less than -5.6 kcal/mol, indicating that each compound and each protein could bind well.Conclusions:Bielong Ruangan decoction participates in the treatment of liver cancer through " multi-component, multi-target and multi-channel" ways, and plays an anti-cancer role mainly by regulating the proliferation and invasion of tumor cells and tumor inflammatory microenvironment.
