目的 基于网络药理学和分子对接方法探究"麦冬-五味子"药对治疗心肌纤维化的作用机制。方法 运用TCMSP数据库及HERB数据库筛选"麦冬-五味子"药对药物成分和靶点，运用GeneCards数据库、Disgenet数据库、OMIM数据库筛选疾病靶点，获取共同靶点;通过Cytoscape软件构建"药物活性成分-疾病-靶点"网络模型;利用微生信平台进行基因本体论功能富集分析(gene ontology，GO)和京都基因与基因组百科全书富集分析(kyoto encyclopedia of genes and genomes，KEGG);利用STRING数据库构建蛋白互作网络;通过Auto Dock Tools1。5。6 软件进行分子对接验证。结果 "麦冬-五味子"药对中共筛选得到戈米辛M2、五味子酚乙、麦冬二氢高异黄酮B等 85 个活性成分，主要作用于HSP90AA1、AKT1、SRC等 163 个心肌纤维化靶点上，主要富集在脂质与动脉粥样硬化信号通路、糖尿病并发症中的age-rage信号通路、癌症发病途径信号通路等相关通路上。结论 "麦冬-五味子"药对主要通过调控炎性反应、氧化应激、脂质沉积、细胞增殖凋亡等多种生物过程来抑制心肌纤维化。
Exploring the mechanism of"Ophiopogon-Schisandra"drug pair in treating myocardial fibrosis based on network pharmacology
Objective To explore the mechanism of"Ophiopogon-Schisandra"drug pair in treating myocardial fibrosis through network pharmacology and molecular docking methods.Methods The TCMSP database and HERB database were used to screen the drug components and targets of the"Ophiopogon-Schisandra"drug pair.The GeneCards database,Disgene database,and OMIM database were used to screen disease targets and obtain common targets;Cytoscape software was used to construct a"drug active ingredients-diseases-targets"network model;the microbiome platform was used for gene ontology functional enrichment analysis(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG);STRING database was used to construct protein interaction networks;molecular docking validation was performed using Auto Dock Tools1.5.6 software.Results 85 active ingredients,including Gomicin M2,Schisandrin B and ophiopogon dihydrohomoisoflavone B,were screened from"Ophiopogon-Schisandra"drug pair,which mainly acted on 163 myocardial fibrosis targets,such as HSP90AA1,AKT1,SRC,and mainly enriched lipid and atherosclerosis signaling pathways,age rage signaling pathway in diabetes complications pathways in cancer and related pathways.Conclusion"Ophiopogon-Schisandra"drug pair mainly inhibits myocardial fibrosis by regulating various biological processes such as inflammatory response,oxidative stress,lipid deposition,cell proliferation and apoptosis.
