(Submitter supplied) Enhancer profiling has emerged as a powerful approach for discovering the cis-regulatory elements that define transcriptional core regulatory circuits. Characteristic biochemical and biophysical attributes of chromatin mark active enhancer elements, which can be leveraged with genome-wide assay technologies for discovery. This includes chromatin immunoprecipitation followed by sequencing (ChIP-seq) for histone H3 acetylated lysine 27 (H3K27ac). more...

(Submitter supplied) Proinflammatory stimuli rapidly and globally remodel chromatin landscape, thereby enabling transcriptional responses. Yet, the mechanisms coupling chromatin regulators to the master regulatory inflammatory transcription factor NF-kB remain poorly understood.  We report in human endothelial cells (ECs) that activated NF-kB binds to enhancers, provoking a rapid, global redistribution of BRD4 preferentially at super-enhancers, large enhancer domains highly bound by chromatin regulators. more...

(Submitter supplied) In chronic lymphocytic leukemia (CLL) a diverse set of genetic mutations is embedded in a deregulated epigenetic landscape that drives cancerogenesis. To elucidate the role of aberrant chromatin features, we mapped DNA methylation, 7 histone modifications, nucleosome positions, chromatin accessibility, binding of EBF1 and CTCF as well as the transcriptome of B cells from CLL patients and healthy donors. more...

(Submitter supplied) Bromodomain and extra-terminal (BET) family proteins are key regulators of gene expression in cancer. Herein, we utilize BRD4 profiling to identify critical pathways involved in pathogenesis of chronic lymphocytic leukemia (CLL). BRD4 is over-expressed in CLL and is enriched proximal to genes up-regulated or de novo expressed in CLL with known function in disease pathogenesis and progression. These genes, including key members of the BCR signaling pathway, provide rationale for this therapeutic approach to identify new targets in alternative types of cancer. more...

(Submitter supplied) Chronic lymphocytic leukemia (CLL) is a quiescent B-cell malignancy that depends on transcriptional dysregulation for survival. The histone deacetylases are transcriptional regulators whose role within the regulatory chromatin and consequence on the CLL transcriptome is poorly characterized. Here, we profiled and integrated the genome wide occupancy of HDAC1, BRD4, H3K27Ac and H3K9Ac signals with chromatin accessibility, Pol2 occupancy and target expression signatures in CLL cells. more...

(Submitter supplied) Bromodomain and extra terminal domain (BET) inhibition reduces occupancy of BET-family proteins at promoter and enhancer sites finally leading to genome wide changes in gene transcription. We used ChIPSeq profiling to investigate genome wide changes in promoter and enhancer occupancy induced by BET inhibitors BAY 1238097 and OTX-015, respectively.

(Submitter supplied) The bromodomain and extraterminal (BET) protein Brd4 is a validated drug target in leukemia, yet its regulatory function in this disease is not well understood. Here, we show that Brd4 chromatin occupancy in acute myeloid leukemia closely correlates with the hematopoietic transcription factors (TFs) Pu.1, Fli1, Erg, C/EBPα, C/EBPβ, and Myb at nucleosome-depleted enhancer and promoter regions. We provide evidence that these TFs, in conjunction with the lysine acetyltransferase activity of p300/CBP, facilitate Brd4 recruitment to their occupied sites to promote transcriptional activation. more...

(Submitter supplied) Gastrointestinal stromal tumor (GIST) is a mesenchymal neoplasm characterized by activating mutations in the related receptor tyrosine kinases KIT or PDGFRA. GIST relies on expression of these unamplified receptor tyrosine kinase (RTK) genes through a large enhancer domain, producing high expression levels of the oncogene required for tumor growth. Though kinase inhibition is an effective therapy for many GIST patients, disease progression from kinase resistance mutations is common, and no other efficacious classes of systemic therapy exist. more...
