摘要目的 对家族性偏瘫性偏头痛 1 型(FHM1)小鼠诱发皮质扩散性抑制(CSD)后皮质转录本中发现的差异表达基因(DEGs)进行生物信息学分析和治疗药物预测。方法 利用 R 软件中的 Deseq2 包从基因芯片公共数据库(GEO)发表的 FHM1 小鼠诱发 CSD 后皮质转录本中筛选出 DEGs 和基因本体论(GO)功能富集分析,并利用 clusterProfiler 包进行信号通路功能富集分析(GSEA)以及 STRING 11.0、CMap等分析平台构建蛋白质相互作用网络和化合物预测,同时利用 Cytoscape 中的 CytoHubba 插件筛选出核心DEGs 并对其进行功能注释。结果 FHM1 型小鼠 CSD 发作后共筛选出 155 个上调基因和 35 个下调基因。DEGs 主要富集于细胞通讯、小分子 GTP 酶介导的信号转导、轴突的发育以及细胞内转运的调节等生物学过程和一些免疫炎症反应相关通路以及 microRNA、细胞因子信号通路上,并筛选出芹菜素、1,4-屈烯醌、非诺特罗等可逆转 DEGs 的小分子化合物。结论 FHM1 型小鼠 CSD 发作后与健康对照组小鼠相比DEGs 存在明显差异。多个信号通路、多个蛋白质相互作用方式为了解偏头痛 CSD 发作后皮质的病理过程提供了帮助。

AbstractObjective To analyze the differential expression genes(DEGs)in cortical transcripts of CSD induced by familial hemiplegic migraine type 1(FHM1)mice and to predict therapeutic agents. Methods DEGs and gene ontology(GO)funct ional enrichment analysis were screened from cortical transcripts of CSD induced by FHM1 mice published in gene chip public database(GEO)by Deseq2 package in R software. ClusterProfiler package was used for signal pathway functional enrichment analysis(GSEA),STRING 11.0,CMap and other analysis platforms to construct protein interaction networks and compound prediction. At the same time, CytoHubba plugin in Cytoscape was used to screen out the core DEGs and annotate its functions. Results A total of 155 up-regulated genes and 35 down-regulated genes were screened after CSD onset in FHM1 mice. DEGs are mainly enriched in biological processes such as cell communication,small molecule GTP-mediated signal transduction,axon development,and intracellular transport regulation,as well as some inflammatory immune response-related pathways,microRNA,and cytokine signaling pathways. Lemepromazine,podophyllotoxin,W-13 hydrochloride,and other small molecule compounds that can reverse DEGs were screened. Conclusion After CSD onset,the DEGs of FHM1 mice are significantly different from those of healthy control mice. Multiple signaling pathways and multiple protein interaction modes help understand the pathological process of cortex after a CSD attack in migraine.
