摘要
目的利用网络药理学结合GEO基因芯片分析的方法,研究复方苦参注射液治疗宫颈癌的靶点和分子机制。方法首先利用TCMSP、TCMID、SwisstargetpredicitionTCMIP等数据库筛选收集复方苦参注射液的化合物和靶点。然后利用GEODataset数据库获取宫颈癌芯片数据,再通过R软件获得其差异基因,同时绘制火山图和热图。再利用R软件对复方苦参注射液靶标基因与GEO差异基因取交集,作为复方苦参注射液治疗宫颈癌的潜在作用靶标,通过string数据库和Cytoscape3.7.2软件对交集基因进行蛋白相互作用网络富集分析并图示化,利用Cytoscape3.7.2软件制作药物-化合物-靶点-疾病网络图。最后利用R语言的clusterfiler程序包对复方苦参注射液治疗宫颈癌的潜在作用靶标进行GO富集分析和KEGG信号通路富集分析。结果复方苦参注射液治疗宫颈癌候选活性成分共计178个,包括苦参碱、槐定碱、右旋异苦参碱等;118个潜在作用靶标,包括OPN、MMP-9、SIRT1、VEGFR-3等;135条通路,包括PI3K-Akt、apelin/APJ、P38MAPK、NF-kB、AMPK等信号通路。分子对接表明苦参碱与3个关键候选靶蛋白(CCND1、CDK1、MMP-9)有较好的结合性。结论研究揭示了复方苦参注射液在治疗宫颈癌中化合物、作用靶标和作用机制,丰富其临床与实验应用的理论基础。
Objective To study the target and molecular mechanism of compound Sophora flavescens injection in the treatment of cervical cancer.Methods Firstly,Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform,Traditional Chinese Medicines Integrated Database,Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine were used to screen and collect the compounds and targets of compound Sophora flavescens injection.Then GEO database was used to obtain cervical cancer gene expression data.Then differently expressed genes were acquired through R software.The overlapped genes of the target genes of compound Sophora flavescens injection and the differently expressed genes were taken as the potential target of compound Sophora flavescens injection in the treatment of cervical cancer.The protein interaction network was enriched and analyzed by string database and Cytoscape 3.7.2 software.The R package clusteProfiler was used to do enrichment analysis.Results There were 178 candidate active ingredients in compound Sophora flavescens injection including matrine,sophoridine,d-isomatrine,etc;118 potential targets,including OPN,MMP-9,SIRT1,VEGFR-3,etc;135 pathways,including PI3K Akt,Apelin/APJ,p38MAPK,NF KB,AMPK,and other signal pathways.Molecular docking showed that matrine had good binding with three key candidate target proteins(CCND1,CDK1 and MMP-9).Conclusion The study provided potential molecular target and mechanism of compound Sophora flavescens injection in the treatment of cervical cancer and enriches the theoretical basis of its clinical and experimental application.
