TheSalvia miltiorrhiza-Codonopsis pilosula drug pair is effective at treating POF;however, knowledge of the mechanisms ofS. miltiorrhiza-C. pilosula in the treatment of POF is lacking. Thus, we carried out network pharmacology and molecular docking to clarify the mechanisms of this drug pair.Methods: The core components and targets ofS. miltiorrhiza-C. pilosula were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database and UniProt database, and the disease targets related to POF were searched using different tools to obtain the overlapping target genes ofS. miltiorrhiza andC. pilosula. A protein interaction network of the intersection target was constructed using STRING database, and the network of "traditional Chinese medicine-active ingredient-intersection target-disease" and "pathways-targets" was constructed using Cytoscape 3.8.0. The DAVID online tool was also used to determine the gene ontology functions and Kyoto Encyclopedia of Genes and Genomes pathways associated with the intersection target genes. Finally, the binding ability of the drug to the active components and potential targets were predicted using molecular docking.Results: S. miltiorrhizae-C. pilosula had 72 active components, 128 targets, 3,775 POF targets, and 106 common targets. The potential targets were mainly related to the biological processes of DNA-binding transcription factor binding, RNA polymerase II-specific DNA-binding transcription factor binding, transcription factor activity, steroid receptor activity, and hypoxia response. Further, the Kyoto Encyclopedia of Genes and Genomes enrichment pathways included PI3K-Akt signaling pathway, apoptosis, interleukin (IL)-17 signaling pathway, relaxin signaling pathway, and other biological pathways.Conclusion(s): S. miltiorrhiza-C. pilosula can inhibit ovarian granulosa cell apoptosis and improve ovarian hemodynamics through multiple targets and multiple pathways and help treat POF.展开更多

文摘Objective:Using network pharmacology to explore the mechanism of the'invigorating qi and promoting blood circulation'drug pair Ginseng-Danshen(Salvia miltiorrhiza)on treatment of ischemic heart disease(IHD).Methods:The chemical constituents of ginseng and Danshen drug pair were identified by searching the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),and the potential targets of the pair were identified.The pharmacodynamics of the pair was analyzed using network pharmacology.The targets of IHD were identified by database screening.Using protein-protein interaction network,the interaction targets of Ginseng-Danshen on IHD were constructed.A"constituent-target-disease"interaction network was constructed using Cytoscape software,Gene Ontology(GO)term enrichment analysis and biological pathway enrichment analysis were carried out,and the mechanism of improving myocardial ischemia by the Ginseng-Danshen drug pair was investigated.Results:Seventeen active constituents and 53 targets were identified from ginseng,53 active constituents and 61 targets were identified from Danshen,and 32 protein targets were shared by ginseng and Danshen.Twenty GO terms were analyzed,including cytokine receptor binding,cytokine activity,heme binding,and antioxidant activity.Sixty Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathways were analyzed,including phosphatidylinositol 3-kinase-serine-threonine kinase(PI3 K-AKT)signaling pathway,p53 signaling pathway,interleukin 17 signaling pathway,tumor necrosis factor signaling pathway,and the advanced glycation end product(AGE)-the receptor for AGE(RAGE)signaling pathway in diabetic complications.Conclusion:The specific mechanism of Ginseng-Danshen drug pair in treating IHD may be associated with improving the changes of metabolites inbody,inhibiting the production of peroxides,removing the endogenous oxygen free radicals,regulating the expression of inflammatory factors,reducing myocardial cell apoptosis and promoting vascular regeneration.

文摘Objective: Premature ovarian failure (POF) is a disease characterized by irregular menstruation and results in infertility which markedly affects the reproductive health of women. TheSalvia miltiorrhiza-Codonopsis pilosula drug pair is effective at treating POF;however, knowledge of the mechanisms ofS. miltiorrhiza-C. pilosula in the treatment of POF is lacking. Thus, we carried out network pharmacology and molecular docking to clarify the mechanisms of this drug pair.Methods: The core components and targets ofS. miltiorrhiza-C. pilosula were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database and UniProt database, and the disease targets related to POF were searched using different tools to obtain the overlapping target genes ofS. miltiorrhiza andC. pilosula. A protein interaction network of the intersection target was constructed using STRING database, and the network of "traditional Chinese medicine-active ingredient-intersection target-disease" and "pathways-targets" was constructed using Cytoscape 3.8.0. The DAVID online tool was also used to determine the gene ontology functions and Kyoto Encyclopedia of Genes and Genomes pathways associated with the intersection target genes. Finally, the binding ability of the drug to the active components and potential targets were predicted using molecular docking.Results: S. miltiorrhizae-C. pilosula had 72 active components, 128 targets, 3,775 POF targets, and 106 common targets. The potential targets were mainly related to the biological processes of DNA-binding transcription factor binding, RNA polymerase II-specific DNA-binding transcription factor binding, transcription factor activity, steroid receptor activity, and hypoxia response. Further, the Kyoto Encyclopedia of Genes and Genomes enrichment pathways included PI3K-Akt signaling pathway, apoptosis, interleukin (IL)-17 signaling pathway, relaxin signaling pathway, and other biological pathways.Conclusion(s): S. miltiorrhiza-C. pilosula can inhibit ovarian granulosa cell apoptosis and improve ovarian hemodynamics through multiple targets and multiple pathways and help treat POF.
