基于网络药理学和分子对接技术探讨益气养阴汤治疗甲状腺癌术后的作用机制

Study on the mechanism of Yiqi Yangyin decoction in the treatment of Postoperative thyroid Cancer based on network pharmacology and molecular docking technology

目的:利用网络药理学和分子对接技术探讨益气养阴汤治疗甲状腺癌术后的作用机制。方法:通过本草组鉴(HERB)数据库检索益气养阴汤10味药物化学成分,通过PubChem、SwissADNE筛选药物活性成分,Swiss target prediction预测活性成分作用靶点。在Gene Cards、OMIM、DisGeNET、Drug Bank数据库检索获得甲状腺癌术后的疾病靶点。Venny2.1.0平台获得药物与疾病的交集靶点,使用String数据库构建交集靶点蛋白互作网络,并导入Cytoscape3.9.1筛选得到核心靶点蛋白;借助Cytoscape3.9.1构建药物-活性成分-靶点网络图,并获取关键活性成分;使用Metascape数据库进行GO和KEGG富集分析;对关键靶点和关键成分进行分子对接验证。结果:得到益气养阴汤活性成分157种,预测活性成分作用靶点507个,甲状腺癌术后相关疾病靶点1817个,药物活性成分—疾病交集靶点154个。PPI分析得到SRC、HSP90AA1、PIK3R1、PIK3CA、AKT1为关键靶点基因,槲皮素、山柰酚、木犀草素为关键活性成分,分子对接显示关键靶点和关键活性成分具有良好的亲和力。KEGG富集分析提示癌症通路、PI3K-Akt通路、HIF-1通路等是药物作用的关键通路。结论:益气养阴汤可以多成分、多靶点、多通路参与抗炎、抗肿瘤、改善组织微环境,在甲状腺癌术后发挥治疗作用。

Objective:To explore the mechanism of Yiqi Yangyin decoction in the treatment of thyroid cancer by means of network pharmacology and molecular docking technique.Methods:the chemical constituents of 10 kinds of Yiqi Yangyin decoction were searched by HERB database,the active components were screened by PubChem and SwissADNE,and the action targets of active components were predicted by Swisstargetprediction.The disease targets after operation of thyroid cancer were obtained by searching the databases of GeneCards,OMIM,DisGeNET and DrugBank.The intersection target of drug and disease was obtained by Venny2.1.0 platform,the intersection target protein interaction network was constructed by String database,and the core target protein was screened by Cytoscape3.9.1,the drug-active ingredient-target network map was constructed by Cytoscape3.9.1,and the key active components were obtained;the enrichment analysis of GO and KEGG was carried out using Metascape database;and the molecular docking verification of key targets and key components was carried out.Results:157active components of Yiqi Yangyin decoction were obtained,and 507targets of active components were predicted,1817 targets of thyroid cancer-related diseases and 154targets of drug-disease intersection were obtained.The key target genes of SRC,HSP90AA1,PIK3R1,PIK3CA and AKT1 were obtained by PPI analysis.Quercetin,kaempferol and luteolin were the key active components.Molecular docking showed that the key targets and key active components had good affinity.KEGG enrichment analysis showed that cancer pathway,PI3K-Akt pathway and HIF-1 pathway were the key pathways of drug action.Conclusion:Yiqi Yangyin decoction can play a therapeutic role in anti-inflammation,anti-tumor and improving tissue microenvironment with multi-components,multi-targets and multi-pathways.
