TITLE:
摘要: 目的:探索黄芪-葶苈子药对治疗心力衰竭的可能作用机制。方法:采用网络药理学方法。基于类药性和口服生物利用度,通过中药系统药理学数据库分析平台、GeneCards和OMIM数据库、反向分子对接服务器,筛选出黄芪-葶苈子药对治疗慢性心力衰竭的活性成分,并预测其作用靶标;采用Cytoscape 3.6.0软件绘制出黄芪-葶苈子药对的活性成分-慢性心力衰竭作用靶标网络;通过STRING数据库制作靶标相互作用网络,筛选连接度排名前5的靶标,在分子对接服务器中进行分子对接;最后在生物学信息注释数据库中进行基因本体(GO)生物过程分析、京都基因与基因组百科全书(KEGG)通路富集分析。结果:本研究共预测得到28个活性成分,其中黄芪20个、葶苈子12个,包括山柰酚、槲皮素等,有4个成分为二者共有;得到活性成分的作用靶标92个,包括热休克蛋白90α(HSP90AA1)、酪氨酸蛋白激酶SRC基因等;GO生物过程结果显示与线粒体电子传递、线粒体内膜、胞质溶胶、胞外体、线粒体基质、药物反应等相关,KEGG通路富集分析结果显示主要涉及丝裂原活化蛋白激酶(MAPK)信号通路、转化生长因子(TGF)信号通路、磷脂酰肌醇3激酶(PI3K)信号通路、环磷酸腺苷(cAMP)信号通路、蛋白激酶B信号通路、细胞外信号调节激酶1(EPK1)信号通路、核转录因子κB(NF-κB)信号通路等方面。结论:黄芪-葶苈子药对可通过上述HSP90AA1、SRC等多靶点及线粒体电子传递、MAPK信号通路等多通路来治疗慢性心力衰竭;本研究为进一步深入探讨该药对作用的物质基础以及作用机制提供了参考。
ABSTRACT: OBJECTIVE: To explore potential mechanism of “Astragalus membranaceus-Draba nemorosa” couplet medicine for heart failure. METHODS: By network pharmacology, based on drug-like and oral bioavailability, the active components of “A. membranaceus-D. nemorosa” for chronic heart failure were screened and the targets of treating chronic heart failure were predicted by using TCMSP,GeneCards database, OMIM database and DRAR-CPI. The active component-chronic heart failure target network was established by Cytoscape 3.6.0 software. The protein-protein interaction network was constructed by utilizing STRING database. Then top 5 targets in the list of connectivity were screened and performed a molecular docking in molecular docking server. Finally, GO bioprocess analysis and KEGG pathway enrichment analysis were performed in DAVID database. RESULTS: The study predicted 28 active components in total, including 20 A. membranaceus and 12 D. nemorosa, such as kaempferol and quercetin, there were four components in common. Totally 92 target gene of active components were obtained, including heat shock protein 90α (HSP90AA1), tyrosine protein kinase SRC gene, etc. Results of GO bioprocess analysis showed an association with mitochondrial electron transport, mitochondrial intima, cytoplasmic sol, extracellular body, mitochondrial matrix and drug response. KEGG pathway enrichment analysis showed a link with MAPK signal pathway, TGF signal pathway, PI3K signal pathway, cAMP signal pathway, protein kinase B signal pathway, EPK1 signal pathway and NF-κB signal pathway. CONCLUSIONS: “A. membranaceus-D. nemorosa” couplet medicine exerts therapeutic effects on heart failure from multiple targets as HSP90AA1, SRC and mitochondrial electron transport and MAPK signaling pathway. The study can provide reference for further researches on its material basis and mechanism.
