目的应用网络药理学分析方法,从整体水平观察牛黄-靶点-角膜炎的复杂网络关系,探讨牛黄治疗角膜炎的分子作用机制。
方法首先通过DisGeNET在线数据库收集角膜炎相关的基因,构建角膜炎相关蛋白质的互作网络,然后经中药系统药理学分析(TCMSP)平台、中国科学院化学数据库查询,结合文献报道,收集牛黄中分离鉴定的组成成分,导出各成分SMILES结构式信息,利用在线软件SwissTargetPrediction预测作用靶点,进而构建牛黄活性成分-预测靶点网络图,最后将角膜炎相关蛋白质的互作网络与牛黄活性成分-预测靶点网络进行合并,得到牛黄活性成分-潜在靶点网络,系统分析牛黄治疗角膜炎的潜在作用靶点及其在信号通路中的作用,构建成分-靶点-通路网络图,分析牛黄治疗角膜炎的作用机制。
结果共搜索到39个已分离鉴定的牛黄组成成分,角膜炎相关靶点65个,牛黄治疗角膜炎的潜在靶点28个;28个潜在靶点中包含7个直接作用靶点,即肿瘤坏死因子、含半胱氨酸的天冬氨酸蛋白水解酶-1、Toll样受体9、C-X-C基序趋化因子配体8、白细胞介素(IL)6、丝裂原活化蛋白激酶8和神经营养受体酪氨酸激酶1。28个潜在靶点可被注释入12项生物过程、18项细胞组分、13个分子功能,经京都基因与基因组百科全书(KEGG)通路富集分析,共纳入10条KEGG信号通路,主要涉及人巨细胞病毒感染、阿米巴病、抗叶酸耐受性、PI3K-Akt信号通路、类风湿性关节炎、凋亡、细胞因子-细胞因子受体相互作用、疟疾、非酒精性脂肪肝、IL-17信号通路。
结论牛黄可能通过抗炎、抗菌、抗病毒、免疫调节和炎症调控等作用发挥对角膜炎的辅助治疗作用。
ObjectiveTo investigate the complex Calculus Bovis-target-keratitis network and to explore the molecular mechanism of Calculus Bovis treating keratitis through network pharmacology.
MethodsGenes related to keratitis were searched in the online DisGeNET database and the protein-protein interaction (PPI) network of keratitis-associated proteins was constructed.The components isolated and identified in Calculus Bovis were collected through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP, https: //tcmsp-e.com/tcmsp.php), Chemistry Database by Shanghai Institute of Organic Chemistry of CAS (http: //www.organchem.csdb.cn), and published literature.The canonical SMILES information of the collected components was exported, which were submitted to the SwissTargetPrediction platform to predict potential targets of the components.The active component-predicted target network of Calculus Bovis was constructed and merged with the PPI network of keratitis-associated proteins to build the active component-potential target network of Calculus Bovis and systemically investigate the potential targets and signal pathways of Calculus Bovis in treatment of keratitis.The component-target-pathway network was established to analyze the mechanism of Calculus Bovis treating keratitis.
ResultsThirty-nine components isolated and identified in Calculus Bovis were searched and 65 target genes related to keratitis were screened.Of the 28 potential targets involved in Calculus Bovis treating keratitis, there were 7 direct targets, including tumor necrosis factor, caspase 1, Toll-like receptor 9, C-X-C motif chemokine ligand 8, interleukin-6, mitogen-activated protein kinase 8, neurotrophic receptor tyrosine kinase 1.The 28 potential targets were annotated to 12 entries for biological process, 18 for cellular components and 13 for molecular function.In the Kyoto encyclopedia of genes and genomes pathway enrichment analysis, 10 signal pathways were identified as enriched categories, which were mainly related to human cytomegalovirus infection, amoebiasis, antifolate resistance, PI3K-Akt signaling pathway, rheumatoid arthritis, apoptosis, cytokine-cytokine receptor interaction, malaria, non-alcoholic fatty liver disease, interleukin-17 signaling pathway.
Conclusions Calculus Bovis may play an adjuvant therapeutic effect on keratitis through anti-inflammatory, antibacterial, antiviral, immune regulation, inflammatory regulation and other functions.
