Abstract:
Objective:To screen the main active components of Danggui Buxue Decoction in improving chemotherapy-induced myelosuppression; To predict the key targets and signaling pathways; To establish a multi-level network structure and comprehensively reveal the synergistic mechanism of Danggui Buxue Decoction in improving chemotherapy-induced myelosuppression.Methods:Main components of Danggui Buxue Decoction were searched in TCMSP detabase, combined with literature reports to supplement and improve information. The protein targets of compounds were standardized in the UniProt protein database. Myelosuppression targets were obtained by querying TTD database, GeneCards database, DrugBank detabase and OMIM database. The effective components and common targets of Danggui Buxue Decoction were screened, and the protein-protein interaction (PPI) network of intersection targets was analyzed by String platform to construct the PPI network of effective components and disease targets. Gene ontology (GO) analysis and enrichment pathway analysis of Kyoto gene and genome encyclopedia (KEGG) of key target proteins were conducted through Metascape data platform. Both the results of GO and KEGG analysis were presented. AutoDock software was used for molecular docking to explore the interaction between core targets and active components, and the results were imported into PyMOL software for visual analysis.Results:Danggui Buxue Decoction has a total of 22 active components of Chinese materia medica for improving chemotherapy-induced myelosuppression, 294 potential targets, 3 301 disease targets, and 210 common targets of Chinese materia medica and diseases. Core targets were obtained through network topology analysis and molecular docking. The first five were ESR1, MAPK1, RELA, AKT1, PIK3R1; GO enrichment results obtained 2 430 biological processes, 125 cellular components and 217 molecular functions, including responses to inorganic substances, membrane rafts, micro-organisms membrane region, transcription factor binding, etc.; KEGG enriched 385 pathways, of which cancer pathway, PI3K-Akt signaling pathway, AGE-RAGE signaling pathway, etc. were the main signaling pathways; molecular docking results showed that β-sitosterol has the best binding performance with HSP90AA1, formononetin and RELA in astragalus when it was in Angelicae Sinensis Radix.Conclusion:Danggui Buxue Decoction regulates ESR1, MAPK1, RELA, AKT1 and other core targets through various active components such as quercetin, formononetin, and β-sitosterol. PI3K-AKT and other related signaling pathways can improve chemotherapy-induced myelosuppression and provide a basis for its clinical application.
