Title ChIP-Seq of H4K5acK8ac, H3K27ac, H3K4me1, H3K4me3, H3K36me3, H3K9me3, H3K27me3 and BRD2 in H23 NSCLC cell line
Organism Homo sapiens
Experiment type Genome binding/occupancy profiling by high throughput sequencing
Summary The bromodomain and extra-terminal domain (BET) proteins are known as drug targets in diseases. However, the BET protein association profile to histone H4 hyperacetylation is not well understood and BET inhibition effects have been studied more in the context of BRD4 than BRD2. Here, by integrating chromatin and transcriptome analyses of ChIP-seq and Cap Analysis Gene Expression (CAGE) datasets, we show that di-acetylation at K5 and K8 of histone H4 (H4K5acK8ac) co-localizes with H3K27ac and BRD2 in the majority of active enhancers and promoters, where BRD2 has a stronger association with H4K5acK8ac than H3K27ac. Interestingly, although BET inhibition by JQ1 led to complete reduction of BRD2 binding, only local changes of H4K5acK8ac were observed and surprisingly a remarkable number of BRD2-bound genes including MYC and its target genes were upregulated. Using BRD2-enriched sites and transcriptional activity analysis, we identified candidate transcription factors (TFs) potentially involved in the JQ1 response in BRD2-dependent and independent manner.
