基于网络药理学的淫羊藿抗疲劳作用机制研究

目的利用网络药理学的方法研究淫羊藿抗疲劳的作用机制。方法利用中药系统药理数据库和分析平台(TCMSP)获取淫羊藿的活性成分及活性成分的作用靶点;在GeneCards数据库中检索与疲劳相关的靶点;由Cytoscape 3.6.1构建活性成分-疾病-靶点网络;String数据库构建靶点蛋白互作网络;DAVID数据库对靶点基因进行基因本体(GO)富集分析及京都基因和基因组百科全书(KEGG)通路富集分析。结果从淫羊藿中筛选得到9种具有抗疲劳作用的活性成分:金圣草(黄)素、山柰酚、脱水淫羊藿素、C-homoerythrinan,1,6-didehydro-3,15,16-trimethoxy-,(3.beta.)-、8-(3-methylbut-2-enyl)-2-phenylchromone、木犀草素、广玉兰内酯、槲皮素、8-isopentenyl-kaempferol,作用于PPARG、GABRA1、CASP3、ICAM1等31个疲劳靶点,生物功能与通路富集分析表明,淫羊藿主要涉及细胞的缺氧反应、凋亡过程的调控、一氧化氮生物合成过程的正向调节、细胞对过氧化氢的反应、血糖稳态、细胞对高氧的反应、脂质贮存负调节等生物过程,通过调节PI3K-Akt、P53、HIF-1、TNF、Fox O、ErbB、MAPK等信号通路来发挥抗疲劳作用。结论研究结果体现了淫羊藿抗疲劳多成分、多靶点、多途径的作用特点,为淫羊藿抗疲劳的进一步研究提供参考。

Mechanism of anti-fatigue of Epimedii Folium based on network pharmacology

Objective To study the anti-fatigue mechanism of Epimedii Folium by network pharmacology. Methods The main active ingredients of Epimedii Folium and the targets of active ingredients were obtained by TCMSP. The GeneCards was used to predict and screen the anti-fatigue targets. The Cytoscape 3.6.1 software was used to construct the active ingredient-disease-target network. The protein interactions network was constructed using the String database. The GO enrichment and KEGG pathways of the targets were analyzed by using DAVID database. Results Nine active ingredients were screened from Epimedii Folium, including chrysoeriol, kaempferol, anhydroicaritin, C-homoerythrinan,1,6-didehydro-3,15,16-trimethoxy-,(3.beta.)-, 8-(3-methylbut-2-enyl)-2-phenyl-chromone, luteolin, magnograndiolide, quercetin, 8-isopentenyl-kaempferol, which acted on 31 fatigue targets such as PPARG, GABRA1, CASP3, ICAM1, etc. Biological function analysis showed that the targets of Epimedii Folium included cellular response to hypoxia, regulation of apoptotic, positive regulation of nitric oxide biosynthetic, cellular response to hydrogen peroxide, cellular response to hyperoxia, and negative regulation of lipid storage. Signaling pathway analysis showed that Epimedii Folium exerted the anti-fatigue effect by regulating PI3K-Akt, P53, HIF-1, TNF, FoxO, ErbB, MAPK, and other pathways. Conclusion This study reflects the characteristics of multi-component, multi-target, and multi-pathway of Epimedii Folium, which provides reference for further research on the mechanism of anti-fatigue effects of Epimedii Folium.
