【摘要】：本研究基于RNA-seq數(shù)據(jù)分析了膠質(zhì)母細胞瘤中的差異表達基因,并對差異表達基因進行了功能(GO term)和通路(KEGG)富集分析。進一步通過蛋白相互作用網(wǎng)絡(luò)挖掘了膠質(zhì)母細胞瘤的調(diào)控機理。結(jié)果表明,405個基因在腫瘤組織中差異表達(p-value≤0.05,|log FC|≥1.5),其中216個(53.3%)基因上調(diào),189個(46.6%)基因下調(diào)。基因本體(gene ontology,GO)富集結(jié)果表明,這些差異表達基因參與了離子轉(zhuǎn)運,神經(jīng)沖動傳遞,細胞信號轉(zhuǎn)導和細胞粘附等。此外,KEGG通路富集結(jié)果表明,差異基因參與了許多重要的生物學通路,包括ECM受體相互作用、黏著和鈣信號等通路。進一步的蛋白相互作用網(wǎng)絡(luò)分析鑒定了5個關(guān)鍵的hub基因,包括PTK2B、CDK1、FN1、CCND1和FOS。這5個關(guān)鍵基因?qū)τ谀z質(zhì)母細胞瘤的發(fā)生和發(fā)展可能起到了關(guān)鍵作用,可以作為潛在的調(diào)控位點和篩選的標志物。
