[Abstract]
Objective To establish a chemical constituents-disease target-metabolic signaling pathway network of Cimicifugae Rhizoma for understanding its mechanism on anti-breast cancer. Methods TCMSP database and PharmMapper were used to obtain the chemical components and action targets of Cimicifugae Rhizoma. The therapeutic targets of anti-breast cancer were obtained by intersecting these targets above with those of breast cancer disease. Then, the reverse screening was executed for the potential active components of Cimicifugae Rhizoma. Indirect targets and protein-targets interaction networks were acquired through the GeneMANIA database, and key targets were screened through protein-protein interaction. Cytoscape was used to construct the "medicinal materia-ingredient-target" network diagram, and molecular docking was used to pair up potential active components with key targets, which confirmed the credibility of early target screening and reverse pharmacophore matching methods. Targets were imported into DAVID database for GO function enrichment analysis and KEGG pathway analysis, the results were visualized using R language and Omishare Tools. Results Tatolly 68 potential active ingredients of Cimicifugae Rhizoma and 48 breast cancerrelated disease targets were obtained, the key targets were ESR1, SRC, and HRAS. A total of 75 GO items were obtained by GO functional enrichment analysis, including 484 biological processes (BP), and seven cell component (CC) items. KEGG enrichment analysis yielded 21 pathways. The result of molecular docking suggested that key targets paired well with the potential active components of Cimicifugae Rhizoma. Conclusion Cimicifugae Rhizoma carried out its therapeutic means in breast cancer treatment mainly through its behaviors of acting on targets such as ESR1, SRC, HRAS, etc, and regulating pathways in cancer, proteoglycans in cancer, and estrogen signaling pathway.
