目的 探索多靶点激酶抑制药GNF-7对白血病细胞表达谱的影响.方法 从基因表达公共数据库下载表达谱数据集GSE49534,用BRB-ArrayTools软件包筛选差异表达基因(DEGs),分别对差异基因进行基因本体(GO)功能分析、通路富集分析、基因互作网络分析和通路互作网络分析.结果 共筛选出847个差异基因,其中上调表达基因426个,下调表达基因419个.DEGs发挥的分子功能集中在结合、蛋白激酶活性和信号转导因子活性等,主要参与信号转导、小分子代谢和细胞凋亡等生物学过程.DEGs显著富集的通路有核糖体合成、代谢通路、Janus激酶-信号转导和转录激活因子(JAK-STAT)信号通路等.网络分析挖掘出的核心基因有多核糖核苷酸核苷酸转移酶1(PNPT1)、腺苷酸激酶4(AK4)、Janus激酶2(JAK2)、信号转导和转录激活因子2(STA T2)、MYC,核心pathway包括丝裂原活化蛋白激酶(MAPK)信号通路、凋亡、细胞周期和肿瘤通路等.结论 GNF-7通过诱导凋亡和细胞周期阻滞等抑制白血病细胞.“,”Objective To explore the effect of multitargeted kinase inhibitor GNF-7 on the expression profiling of leukemia cell lines.Methods The expression profiles dataset GSE49534 was downloaded from the Gene Expression Omnibus (GEO) database.The BRB-Array Tools software package was employed to screen the differentially expressed genes (DEGs),then the Gene Ontology (GO) function,pathway enrichment,gene interaction network,and pathway relation network analyses were conducted based on these differential genes.Results Totally,847 differential genes were screened out,of which 426 genes were up-regulated and 419 genes were down-regulated.GO enrichment analysis showed that DEGs mainly performed the molecular functions of binding,protein kinase activity,and signal transducer activity,and participated in biological process of signal transduction,small molecule metabolic process,and apoptotic process.The pathway analysis found that DEGs were mostly enriched in ribosome biogenesis in eukaryotes,metabolic pathways,Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway,etc.The network analyses mining identified the hub genes,which included polyribonucleotide nucleotidyltransferase 1 (PNPT1),adenylate kinase 4 (AK4),Janus kinase 2 (JAK2),signal transducer and activator of transcription 2 (STAT2),MYC;and core pathways such as mitogen-activated protein kinase (MAPK) signaling pathway,apoptosis,cell cycle,pathways in cancer.Conclusion The GNF-7 inhibited leukemia cells via induction of apoptosis and cell cycle arrest.
