摘要
本文旨在分析阿尔茨海默病(AD)中的microRNA(miRNA)特征,发现miRNA的显著表达、其靶基因、已确认基因的功能富集分析以及潜在的药物治疗。基因表达谱数据中的 miRNA 表达信息是从基因表达总库(Gene Expression Omnibus)数据库中下载的。数据样本总量为 1309 个,包括 1021 个 AD 样本和 288 个正常样本。共获得 21 个差异表达的 miRNA,其中 16 个(hsa-miR-6761-3p、hsa-miR-6747-3p、hsa-miR-6875-3p、hsa-miR-6754-3p、hsa-miR-6736-3p、hsa-miR-6762-3p、hsa-miR-6787-3p、hsa-miR-208a-5p、hsa-miR-6740-3p、hsa-miR-6778-3p、在 AD 中,hsa-miR-208a-5p、hsa-miR-6740-3p、hsa-miR-6778-3p、hsa-miR-595、hsa-miR-6753-3p、hsa-miR-4747-3p、hsa-miR-3646、hsa-miR-6716-3p 和 hsa-miR-4435)上调,5 个 miRNA(hsa-miR-125a-3p、hsa-miR-22-3p、hsa-miR-24-3p、hsa-miR-6131 和 hsa-miR-125b-1-3p)下调。共预测了6个miRNA(hsa-miR-595、hsa-miR-3646、hsa-miR-4435、hsa-miR-125a-3p、hsa-miR-22-3p和hsa-miR-24-3p)和78个miRNA-疾病相关基因亚网络,以及116对ceRNA调控关系和ceRNA调控网络。富集分析结果表明,在AD中差异表达的几个miRNA的主要靶标通路是丝裂原活化蛋白激酶信号通路。根据药物基因相互作用数据库2.0的预测结果,我们得到了53对药物基因相互作用,包括7个基因(PTGS2、表皮生长因子受体、CALM1、PDE4D、表皮生长因子受体2、HMGCR、cdk6)和53种药物。我们希望我们的研究结果有助于找到预防、延缓发病、诊断和治疗 AD 的可行方法。
This paper was aimed to analyze the microRNA (miRNA) signatures in Alzheimer disease (AD) and find the significant expressions of miRNAs, their target genes, the functional enrichment analysis of the confirmed genes, and potential drug treatment. The miRNA expression information of the gene expression profile data was downloaded from the Gene Expression Omnibus database. The total data sample size is 1309, including 1021 AD samples and 288 normal samples.
