摘要:

文题释义:
网络药理学特点:作为一门新学科被广泛运用于研究中药治疗疾病潜在的分子机制,它通过药物-基因-疾病多层次的网络中药机制分析,系统预测中药对致病基因潜在的药效靶点,科学阐述中药可能在疾病中的作用方式。
骨关节炎中医病机:是一种以关节疼痛、功能障碍为主要表现的骨科常见疾病,在中医属于“痹证”范畴,中国历代医家认为“风、寒、湿”三邪是该病的主要病因。

背景:目前临床运用五苓散治疗膝关节炎疗效确切,但其药理作用、分子机制及药物活性物质尚未明确。
目的:基于网络药理学方法寻找五苓散在治疗骨关节炎方面存在的潜在分子机制,阐述该类分子及相关信号通路作用,为进一步提取关键药物化合物提供理论基础。
方法:运用中药数据库分析平台TCMSP筛选五苓散的活性成分及对应靶点,整合Gene Cards,OMIM和DigSee疾病数据库得到骨关节炎相关靶点,将两者运用Venny平台进行映射交集得到五苓散治疗骨关节炎的潜在作用靶点。利用 Cytoscape 软件构建五苓散治疗骨关节炎的“单味药-活性成分-作用靶点”网络和蛋白质相互作用网络,并使用 David 数据库对五苓散治疗骨关节炎的作用靶点进行GO功能富集分析和 KEGG 通路富集分析,最后运用PyMOL等软件对五苓散的关键活性成分与关键靶点进行分子对接验证。
结果与结论:①共筛选得到五苓散“单味药-活性成分-作用靶点”活性成分包括β-谷甾醇、儿茶素及花旗松素等52个;②蛋白互作分析提示五苓散治疗骨关节炎关键靶点26个,包括可促进软骨细胞增殖,并抑制相关炎性细胞因子表达的雌激素受体1,参与骨关节内炎症反应的肿瘤蛋白p53以及介导细胞凋亡的泛素连接酶CUL3蛋白等;③分子对接结果显示亲和力最低的儿茶素和NTRK1进行分子对接良好,表明预测的五苓散的关键活性成分与治疗骨关节炎的关键作用靶点具有较好的结合活性;④GO富集分析得到GO条目共709个,包括生物过程649个,细胞成分22个和分子功能38个,主要涉及对机体雌激素、炎症和脂多糖的反应;⑤KEGG通路富集分析得到关键蛋白模块的相关通路,包括参与软骨细胞氧化应激、炎症及细胞凋亡过程的AGE-RAGE、白细胞介素17、肿瘤坏死因子、p53及影响软骨细胞增殖与修复的雌激素信号通路等;⑥结果证实,五苓散内具有的活性化合物β-谷甾醇、儿茶素、花旗松素和常春藤皂苷可能通过调节雌激素受体1、TP53、CUL3和MCM2相关蛋白靶点的表达,调控相关信号通路,从而发挥减缓软骨细胞凋亡、加强软骨细胞增殖修复及减轻炎症反应的作用。

Abstract: BACKGROUND: Wuling power has an effective effect in the clinical treatment of knee arthritis, but its pharmacological effects, but its molecular mechanisms and drug active components are not yet clear.
OBJECTIVE: Based on the network pharmacology method, the potential molecular mechanism of Wuling powder in the treatment of osteoarthritis was explored, and the role of these molecules and related signaling pathways was elaborated, providing a theoretical basis for further extraction of key drug compounds. 
METHODS: TCMSP was used to screen the active components and corresponding targets of Wuling powder, and Gene Cards, OMIM and DigSee disease databases were integrated to obtain the related targets of osteoarthritis. The potential targets of Wuling powder in the treatment of osteoarthritis were obtained by mapping and intersection on the Venny platform. The network of “single drug-active component-interaction target” and protein-protein interaction network of Wuling powder in the treatment of osteoarthritis were constructed by using the software of Cytoscape, and the functional enrichment analysis of GO and the enrichment analysis of KEGG pathway of Wuling powder in the treatment of osteoarthritis were carried out by using David database. Finally, the key active components and key targets of Wuling powder were verified through molecular docking by using PyMOL and other software.
RESULTS AND CONCLUSION: A total of 52 active ingredients including β-sitosterol, catechin and taxifolin were screened. The protein-protein interaction analysis indicated that there were 26 key targets of Wuling powder in the treatment of osteoarthritis, including estrogen receptor 1 (ESR1), which can promote the proliferation of chondrocytes and inhibit the expression of related inflammatory cytokines, tumor protein p53 (tumor protein), which is involved in the inflammatory reaction of osteoarthritis p53, and ubiquitin ligase CUL3 (cullin3) that mediates apoptosis. The results of molecular docking showed that catechin with the lowest affinity and NTRK1 had a good molecular docking, indicating that the predicted key active components of Wuling powder have a good binding activity with the key targets of osteoarthritis treatment. There were 709 GO items in total, including 649 biological processes, 22 cell components and 38 molecular functions, which are mainly involved in the response to estrogen, inflammation and lipopolysaccharide. KEGG pathway enrichment analysis showed that the related pathways of key protein modules included AGE-RAGE signaling pathway, interleukin-17 signaling pathway, tumor necrosis factor signaling pathway, p53 signaling pathway, and estrogen signaling pathway, which are involved in the process of oxidative stress, inflammatory response and apoptosis of chondrocytes. The results showed that the active compounds β-sitosterol, catechin, taxifolin and hederagenin in Wuling powder could regulate relevant signaling pathways by regulating the expression of ESR1, TP53, CUL3 and MCM2 related protein targets, which can slow down the apoptosis of chondrocytes, strengthen the proliferation and repair of chondrocytes, and reduce the inflammatory response.
