摘要
目的通过网络药理学初步预测小檗碱抗新型冠状病毒感染的作用靶点及信号通路,初步探讨小檗碱的作用机制。方法从SwissTargetPrediction和PubChem等数据库中获取药物的对应靶点。使用GeneCards和DisGenNET数据库收集疾病的相关靶点。利用venny网站在线工具筛选出药物与疾病的交集靶点,通过STRING数据库及Cytoscape 3.9.1软件构建“药物-靶点-疾病”与PPI网络图。使用DAVID数据库对交集靶点进行GO及KEGG富集分析。结果共获得小檗碱与抗新型冠状病毒感染交集靶点50个。经拓扑学分析获得核心PPI网络,包含17个节点;GO功能分析显示,小檗碱治疗新型冠状病毒感染生物学过程包括:信号转导、蛋白质磷酸化、蛋白质进入细胞核的正向调节等。细胞成分包括:细胞质、等离子体膜、核浆。分子功能包括:丝氨酸/苏氨酸/酪氨酸激酶活性、ATP结合、胰岛素受体结合等。KEGG分析共得到95条富集通路,而其中与新型冠状病毒感染相关的主要信号通路包括VEGF信号通路、趋化因子信号通路、Rap1信号通路和PI3K-Akt信号通路等。结论小檗碱具有抗新型冠状病毒感染作用,其机制可能通过调控VEGF信号通路、趋化因子信号通路、Rap1信号通路和PI3K-Akt信号通路,从而调节免疫反应和炎症激活过程来发挥其治疗作用。
Objective To preliminary predict the targets and signaling pathways of berberine against novel coronavirus infection by network pharmacology,and to preliminarily explore the mechanism of berberine.Methods The corresponding target sites of the drug were obtained from SwissTargetPrediction and PubChem databases.GeneCards and DisGenNET databases were used to collect disease-related targets.Venny website online tool was used to screen the intersection targets of the drug and disease,and the STRING database and Cytoscape 3.9.1 software were used to construct the"drug-target-disease"and PPI network diagram.GO and KEGG enrichment analysis of intersection targets were performed using DAVID database.Results A total of 50 intersection targets of berberine and novel coronavirus infection were obtained.The core PPI network was obtained by topological analysis,which contained 17 nodes.GO functional analysis showed that the biological processes of berberine in the treatment of novel coronavirus infection included:signal transduction,protein phosphorylation,and positive regulation of protein entry into the nucleus.Cellular components include:cytoplasm,plasma membrane,nuclear plasma.Molecular functions include:serine/threonine/tyrosine kinase activity,ATP binding,insulin receptor,etc.A total of 95 enriched pathways were obtained by KEGG pathway analysis,and the main signaling pathways related to novel coronavirus infection included VEGF signaling pathway,chemokine signaling pathway,Rap1 signaling pathway and PI3K-Akt signaling pathway.Conclusion Berberine has anti-novel coronavirus infection effect,which may exert its therapeutic effects by regulating VEGF signaling pathway,chemokine signaling pathway,Rap 1 signaling pathway and PI3K-Akt signaling pathway,thus regulating the immune response and inflammatory activation process.
