目的:采用网络药理学方法探索β-石竹烯(β-caryophyllene,BCP)在脑缺血/再灌注损伤(cerebral ischemia-reperfusion injury,CIRI)中发挥作用的潜在机制,并对关键通路中的关键靶点进行验证。方法:通过PharmMapper(pharmmapper server)...目的:采用网络药理学方法探索β-石竹烯(β-caryophyllene,BCP)在脑缺血/再灌注损伤(cerebral ischemia-reperfusion injury,CIRI)中发挥作用的潜在机制,并对关键通路中的关键靶点进行验证。方法:通过PharmMapper(pharmmapper server)数据库获得BCP相关靶点;通过人类基因数据库(https://www.genecards.org/,GeneCards)和在线人类孟德尔遗传数据库(online mendelian inheritance in man,OMIM)数据库获得CIRI的相关靶点;利用VENNY 2.1.0数据库比对筛选BCP抗CIRI的潜在作用靶点,并利用软件Cytoscape 3.7.1绘制相互图;利用软件R语言中的clusterProfiler包对BCP抗CIRI的潜在靶点进行基因本体论(gene ontology,GO)富集分析及京都基因与基因组百科全书(kyoto encyclopedia of genes and genomes,KEGG)富集通路分析;建立大鼠CIRI模型,用western blot法验证BCP抗CIRI的潜在靶点。结果:筛选出BCP相关靶点194个,CIRI相关靶点1144个,共同靶点102个。BCP主要作用于白细胞介素6(interleukin-6,IL-6)、肿瘤坏死因子(tumor necrosis factor,TNF)、肿瘤蛋白p53(tumor protein p53,TP53)、丝裂原活化蛋白激酶1(mitogen-activated protein kinase 1,MAPK1)、信号转导子和转录激活子3(signal transducer and activator of transcription 3,STAT3)、半胱天冬酶3(caspase 3,CASP3)等关键靶点,通过过氧化物酶体增殖物激活受体(peroxisome proliferator-activated receptors,PPAR)、丝裂原活化蛋白激酶(mitogen-activated protein kinase,MAPK)、核因子κB(nuclear factor kappa-B,NF-κB)、P53(tumor protein p53,P53)等信号通路途径,对CIRI发挥抗炎、抗氧化、抗凋亡、神经保护作用。结论:BCP在CIRI治疗中的作用主要涉及抗凋亡、神经保护作用,其他还与抗炎、抗氧化等多靶点、多通路相关,体现出我国中医药多靶点、多环节发挥作用的特点。展开更多
