Abstract

Many genomic techniques have been developed to study gene essentiality genome-wide, such as CRISPR and shRNA screens. Our analyses of public CRISPR screens suggest protein interaction networks, when integrated with gene expression or histone marks, are highly predictive of gene essentiality. Meanwhile, the quality of CRISPR and shRNA screen results can be significantly enhanced through network neighbor information. We also found network neighbor information to be very informative on prioritizing ChIP-seq target genes and survival indicator genes from tumor profiling. Thus, our study provides a general method for gene essentiality analysis in functional genomic experiments ( http://nest.dfci.harvard.edu ).

功能基因组学实验中基因必要性的网络分析。
许多基因组技术已经发展到研究全基因组的基因必要性,如CRISPR和shRNA筛选。我们对公共CRISPR筛选的分析表明,当与基因表达或组蛋白标记结合时,蛋白质相互作用网络可以高度预测基因的必要性。同时,通过网络邻居信息可以显著提高CRISPR和shRNA筛选结果的质量。我们还发现网络邻居信息对ChIP-seq靶基因和肿瘤谱的生存指示基因的优先排序非常有帮助。因此,我们的研究为功能基因组实验中的基因必要性分析提供了一种通用方法(http://nest.dfci.harvard.edu)。
