摘要:

文题释义:
基因本体(gene ontology,GO):是一个在生物信息学领域中广泛使用的本体,它涵盖生物学的3个方面:细胞组分、分子功能、生物过程。
京都基因与基因组百科全书(KEGG) :是了解高级功能和生物系统(如细胞、 生物和生态系统),从分子水平信息,尤其是大型分子数据集生成的基因组测序和其他高通量实验技术的实用程序数据库资源, 由日本京都大学生物信息学中心的Kanehisa实验室于1995年建立。KEGG是国际最常用的生物信息数据库之一,以“理解生物系统的高级功能和实用程序资源库”著称。

背景:研究显示杜仲有效成分存在抑制关节炎滑膜成纤维细胞生长的作用,但杜仲对膝骨关节炎病变过程的滑膜炎症病变作用的分子机制目前尚不明确。
目的:基于中药网络药理学理论与生物信息学研究方法,探讨中药杜仲治疗膝骨关节炎滑膜炎症病变的可能分子作用机制。
方法:利用中药系统药理学数据库与分析平台(TCMSP)筛选杜仲有效活性成分并预测其作用的疾病靶点。下载基因表达数据库(GEO)中关于膝骨关节炎滑膜炎症病变的基因芯片数据,筛选获得差异表达基因,与杜仲活性成分作用的靶点基因取交集获得目的靶点基因。利用CytoScape软件构建杜仲-活性成分-靶点基因调控网络;使用STRING网站对靶点基因进行蛋白互作网络构建分析,筛选其中关键基因;利用R语言Bioconductor程序包对靶点基因进行基因本体论(GO)与京都基因与基因组百科全书(KEGG)信号通路分析,筛选具有统计学差异(P < 0.05)的生物学过程或信号通路展开进一步分析。
结果与结论:①筛选获得杜仲的21个有效活性成分,包括丁子香萜、杜仲甙、杜仲脂素A、槲皮素等,作用于25个膝骨关节炎滑膜炎症病变靶点基因(7个上调基因、18个下调基因);②靶点基因主要富集于细胞因子活性、细胞因子受体结合、激活转录因子结合等生物学过程;③杜仲有效活性成分可能通过调控白介素6、血管内皮生长因子A、细胞趋化因子8等关键基因的表达,进而调控靶点基因所在的丝裂原活化蛋白激酶信号通路、核因子κB信号通路、Toll样受体信号通路等发挥其治疗滑膜炎症病变的作用;④研究立足于对膝骨关节炎滑膜炎症病变中医病机的辨证论治,运用网络药理学与生物信息学理论方法探讨杜仲治疗该疾病的可能分子作用机制,可为进一步开展相关实验研究提供药效物质基础及思路方向参考。

Abstract: BACKGROUND: Studies have shown that the active ingredients of Eucommia ulmoides can inhibit the growth of synovial fibroblasts of arthritis, but the molecular mechanism underlying  Eucommia ulmoides  treating synovial inflammation of knee osteoarthritis is not yet clear.
OBJECTIVE: To investigate the possible molecular mechanism of  Eucommia ulmoides  ingredients treating synovitis of knee osteoarthritis based on the network pharmacology and bioinformatics. 
METHODS: The active ingredients and targets of  Eucommia ulmoides  were screened by using the TCM systematic pharmacological analysis platform (TCMSP). The disease targets corresponding to synovitis of knee osteoarthritis were obtained from Gene Expression Omnibus (GEO). The protein-protein interaction network was constructed by STRING online database, analyzed and showed by the Cytoscape software. Gene ontology analysis and Kyoto encyclopedia of genes and genomes pathway enrichment analysis of the targets were conducted by R/Bioconductor. The enrichment results were obtained with a significant difference (P < 0.05). 
RESULTS AND CONCLUSION: A total of 21 active ingredients of Eucommia ulmoides, including eugenol, eucommia glycoside, eucommia liposide A, quercetin, and 25 different expressed genes (7 up-regulated and 18 down-regulated differentially expressed genes) were obtained. The main biological processes of the differentially expressed genes were found different significantly in cytokine activity, cytokine receptor binding and activating transcription factor binding. The hub genes, such as interleukin-6, vascular endothelial growth factor A and chemotactic factor 8, may be regulated by the active ingredients to influence the signal of MAPK/NF-kappa B/Toll-like receptor signaling pathway. Based on the network pharmacology and bioinformatics approach, the study preliminarily validates the molecular mechanism of Eucommia ulmoides for treatment of synovitis of knee osteoarthritis, which may lay a foundation for further pharmacodynamics study and experiment.
