Functional CRISPR Screen Identifies AP1-associated Enhancer regulating FOXF1 to modulate Oncogene-Induced Senescence. Functional CRISPR Screen Identifies AP1-associated Enhancer regulating FOXF1 to modulate Oncogene-Induced Senescence

We carried out CRISPR-Cas9 functional screen focused on AP-1 bound enhancers that are activated upon oncogenic stress. The screen discovered Enh.AP1.OIS1 - an enhancer bound by AP1 that is required for activation of oncogene-induced senescence (OIS) response. We applied RNA-seq analysis to RASG12V-activated BJ cells transduced with either sgRNAs targeting AP-1 bound enhancer (sgRNA-69 or sgRNA71), or sgRNA targeting the target gene FOXF1 or non-targeting control sgRNA (sgNT) Overall design: RNA-seq was applied to oncogenic RASG12V-induced BJ cells genetically manipulated using CRISPR-Cas9
