Project description: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. Newly established NF-kB super-enhancers drive nearby canonical inflammatory response genes. In both ECs and macrophages BET bromodomain inhibition prevents super-enhancer formation downstream of NF-kB activation, abrogating proinflammatory transcription. In TNFa-activated endothelium this culminates in functional suppression of leukocyte rolling, adhesion and transmigration. Sustained BET bromodomain inhibitor treatment of LDLr -/- animals suppresses atherogenesis, a disease process rooted in pathological vascular inflammation involving endothelium and macrophages. These data establish BET-bromodomains as key effectors of inflammatory response through their role in the dynamic, global reorganization of super-enhancers during NF-kB activation.

Project description:Super-enhancers are principal determinants of cell transcription, development, phenotype, and oncogenesis, not yet implicated in host-pathogen interactions. We found four Epstein-Barr virus (EBV) oncoproteins and five EBV-activated NF-M-oM-^AM-+B subunits co-occupying thousand of enhancer sites in EBV-transformed lymphoblastoid cells (LCLs). Of these, 187 had markedly higher and broader histone H3K27ac signals characteristic of super-enhancer formation, and were designated M-bM-^@M-^\EBV super-enhancersM-bM-^@M-^]. EBV super-enhancer associated genes included MYC and BCL2, which enable LCL proliferation and survival. EBV super-enhancers were enriched for specific B cell transcription factor motifs and had high STAT5 and NFAT co-occupancy. EBV super-enhancer associated genes were more highly expressed than other LCL genes. Disruption of EBV super-enhancers by the bromo-domain inhibitor, JQ1, by conditional inactivation of an EBV oncoprotein or NF-M-oM-^AM-+B, decreased MYC or BCL2 gene expression and arrested LCL growth. These findings provide novel insights into the mechanisms by which EBV causes lymphoproliferation and identify opportunities for therapeutic intervention. ChIP-seq was used to define the BRD4 genome-wide landscape in GM12878 lymphoblastoid cells.
