今天分享一篇生信文章,題為Identification of Key Genes, MicroRNAs and Potentially Regulated Pathways in Alcoholic Hepatitis by Integrative Analysis,該文章于2019年11月15日發(fā)表于Gene雜志,影響因子為2.638,通訊作者單位是西南醫(yī)科大學(xué)附屬中醫(yī)院臨床實(shí)驗(yàn)室。
?研究思路: ? ??
1.尋找差異表達(dá)基因(DEG)和差異表達(dá)miRNA(DEM):使用GEO public database中GSE28619和GSE59492數(shù)據(jù),用GEO2R做volcano plot;
?2. CEGs采集與KEGG富集分析: Cytoscape software and its CyTargetLinker application (http://www.cytoscape.org/)、Database for Annotation Visualization and Integrated Discovery (DAVID)?
3. Hub基因與關(guān)鍵miRNAs的篩選: PPI網(wǎng)絡(luò)、CyTargetLinker plug-in of Cytoscape ? ?
?4.人群中驗(yàn)證Hub基因與關(guān)鍵miRNAs:Western blot analysis、RT-qPCR analysis ? ??
