The Mechanism of Action of Clove Volatile Oil in the Treatment of Chronic Atrophic Gastritis Based on NetworkPharmacology

目的:基于网络药理学探讨丁香挥发油治疗慢性萎缩性胃炎(CAG)的作用机制。方法:通过GC-MS方法测定丁香挥发油的化学成分,利用TCMSP、PubChem以及Swiss Target Prediction数据库获取相关成分靶点,DisGeNET、OMIM、Gene Card获取CAG相关疾病靶点,运用String数据库构建(蛋白-蛋白相互作用)PPI网络;通过DAVID实现京都基因与基因组百科全书(KEGG)信号通路和基因本体论(GO)功能富集分析。结果:Cytoscape 3.7.1软件进行可视化分析。筛选出22个丁香挥发油化学成分,预测出73个交集靶点。丁香挥发油中的丁香酚、乙酸丁香酚酯等主要化合物通过调节AKT1、VEGFA、SRC、EGFR等关键基因,参与凋亡过程的负调控、炎症反应、RNA聚合酶II启动子转录的正调控等生物过程,调控肿瘤坏死因子信号通路、VEGF信号通路、ErbB信号通路、HIF-1信号通路,可能在治疗CAG中发挥重要作用。结论:本研究预测了丁香挥发油治疗慢性萎缩性胃炎的潜在活性成分和作用靶点及可能的作用机制,为进一步研究丁香挥发油防治慢性萎缩性胃炎的作用机制提供理论依据。

Objetctive: To explore the mechanism of action of clove volatile oil in the treatment of chronic atrophic gastritis(CAG) based on the method of network pharmacology. Methods: The chemical components of the volatile oil of clove were determined by the GC-MS method, and the relevant component targets were obtained by TCMSP, PubChem and Swiss Target Prediction databases, and the CAG-related disease targets were obtained by DisGeNET, OMIM, and Gene Card, and the String database was used to construct(protein-protein interaction) PPI network;realize the Kyoto Encyclopedia of Genes and Genome(KEGG) signaling pathway and gene ontology(GO) functional enrichment analysis through DAVID. Results: Cytoscape 3.7.1 software for visual analysis. Twenty-two chemical constituents of the volatile oil of clove were screened out,and 73 intersection targets were predicted. The main compounds such as eugenol and eugenol acetate in clove volatile oil are involved in the negative regulation of apoptosis process, inflammation, and the positive regulation of RNA polymerase Ⅱ promoter transcription by regulating key genes such as AKT1, VEGFA, SRC, and EGFR. The process, regulation of tumor necrosis factor signaling pathway(TNF signaling pathway), VEGF signaling pathway(VEGF signaling pathway), ErbB signaling pathway(ErbB signaling pathway), HIF-1 signaling pathway(HIF-1 signaling pathway), may be used in the treatment of CAG play an important role. Conclusion: This study predicts the potential active ingredients, targets and possible mechanisms of clove volatile oil in the treatment of chronic atrophic gastritis, and provides a theoretical basis for further research on the mechanism of clove volatile oil in the prevention and treatment of chronic atrophic gastritis.
