基于网络药理学的猫爪草防治疾病的优效组分及信号通路研究

Effective components and signaling pathways of Ranunculi Ternati Radix based on network pharmacology

目的:采用网络药理学筛选出中药猫爪草防治疾病的活性成分,探索其潜在靶点和药理作用机制。方法:通过TCMSP数据库,结合口服利用度(≥30%)和类药性分析(≥0.18)参数,筛选猫爪草的活性成分;从TCMSP数据库中检索化合物的蛋白靶点。通过UniProt数据库获得相关蛋白和基因名称。结合String数据库及Cytoscape软件构建蛋白质相互作用网络。利用DAVID数据库,进行GO分类富集分析和通路富集分析。结果:从猫爪草中提取了β-谷甾醇、菜油甾醇、亚油酸乙酯等10种活性成分。其对不同疾病的作用主要通过调控PIK3CG、HSP90AA1、BAX、BCL2等靶点,这些靶点涉及癌症中包含的信号通路、PI3K-Akt信号通路、乙肝、肺结核等,与部分已发表论文相互印证。本研究还预测了猫爪草具有治疗非酒精性脂肪肝的潜力。结论:本研究初步验证了猫爪草治疗不同疾病的主要靶点和途径,为进一步研究其作用机制奠定了基础。

Objective To study the active components of Ranunculi Ternati Radix using network pharmacology,and to explore its potential target and pharmacological mechanism.Methods TCMSP database was searched,combined with the data of oral bioavailability(≥30%)analysis and resistance(≥0.18),to screen of active ingredients in Ranunculus ternatusThunb.The protein targets of the compounds were retrieved from the TCMSP database.Associated proteins and gene names were obtainedviaUniProt database.The protein interaction network was constructed by applying String database and Cytoscape software.Gene ontology and pathway enrichment analysis were developed on the basis of DAVID database.Results Altogether10 active compounds including beta-sitosterol,campesterol,Mandenol were selected from Ranunculi Ternati Radix.And it produced its effects on different diseases mainly by regulating targets including PIK3CG,HSP90AA1,BAX and BCL2,which involved signaling pathways containing Pathways in cancer,PI3K-Akt signaling pathway,Hepatitis B,Tuberculosis and so on.Some published papers had confirmed by each other.Meanwhile,this work predicted that Ranunculi Ternati Radix had the potential to treat non-alcoholic fatty liver disease.Conclusion This study preliminarily validated the major targets and pathways of Ranunculi Ternati Radix acting on different diseases,which laid a foundation for further study on its mechanisms.
