Explore pharmacological mechanism of glycyrrhizin based on systems pharmacology

该文拟通过一系列系统药理学方法探讨甘草甜素的药理作用机制。运用文本挖掘工具,获得甘草甜素主要相关疾病;在Polysearch和Pub Chem数据库获得甘草甜素的靶蛋白;运用网络可视化软件,构建甘草甜素靶蛋白质相互作用网络;借助基因本位论(GO)工具分析甘草甜素蛋白质群;通路富集分析甘草甜素靶蛋白的作用通路。文本挖掘结果表明甘草甜素主要相关疾病有慢性丙型肝炎、慢性肝炎、肝炎、HIV病毒、肝癌等;基因本位论分析结果表明甘草甜素主要通过修饰蛋白、修饰染色质等作用发挥生物学功能;信号通路富集结果表明甘草甜素主要作用蛋白与MAPK信号通路、Toll样受体信号通路、神经营养因子信号通路、癌症途径以及细胞凋亡等信号通路相关。可见,甘草甜素可能主要通过调控MAPK信号通路、Toll样受体信号通路等多途径发挥其药理作用。综合运用系统药理学的方法可以实现快速而全面的分析药物的药理作用。

To explore the pharmacological mechanism of glycyrrhizin with series methods of systems pharmacology,main diseases related to glycyrrhizin were obtained by text mining tool; and the target proteins of glycyrrhizin were obtained via the database of Polysearch and Pub Chem. Then,the target proteins interaction network of glycyrrhizin was built using the software called Cytoscape. Next,the protein groups related to glycyrrhizin were analyzed by using Gene Ontology（ GO） tool,and the action pathway of its target proteins was analyzed by using enrichment method. Text mining results showed that the related diseases of glycyrrhizin included chronic hepatitis C,chronic hepatitis,hepatitis,HIV virus,liver cancer and so on. Gene ontology analysis indicated that glycyrrhizin played a role mainly through modification of proteins and chromatin. The signaling pathway enrichment results showed that the main action proteins of glycyrrhizin were related to MAPK signaling pathway,toll-like receptor signaling pathway,neurotrophic factor signaling pathway,cancer and apoptosis pathways. So we can conclude that glycyrrhizin may exert its biological functions primarily by regulating multiple pathways such as MAPK signaling pathway and Toll-like receptors signaling pathway. The pharmacological action of a drug can be rapidly and comprehensively analyzed by the ways of systems pharmacology.
