(Submitter supplied) Heart failure can be induced or ameliorated by regulation of chromatin modifying enzymes. Because so many chromatin factors regulate gene expression, we used ATAC-seq to report the status of a given locus at any time—the sum total of all epigenetic modifiers—in a mouse model of pressure overload hypertrophy. Early compensation of pressure overload at 3 days was associated with widespread changes in chromatin accessibility and DNA methylation, the majority of which persisted to the decompensated phase (3 weeks), revealing the temporal nature of epigenomic compensation to pathologic stimuli. more...

(Submitter supplied) Understanding the principles of endogenous chromatin structure has key implications for epigenetic therapy. To determine the mechanisms of genome structure-function in post-mitotic cells, genome-wide chromatin conformation capture was performed in cardiac myocytes, a non-dividing, differentiated cell responsible for cardiac contraction. Cardiac-specific CTCF knockout mice demonstrated that loss of CTCF had minimal effect on topologically associating domains; however, it selectively altered boundary strength and A/B compartmentalization, with gene expression changes mimicking those in heart failure. more...

(Submitter supplied) The Mediator co-activator complex directs gene specific expression by binding distal enhancer-bound transcription factors through its Med1 subunit while bridging to RNA Polymerase-II (Pol-II) at gene promoters. In addition, Mediator scaffolds epigenetic modifying enzymes that determine local DNA accessibility. We previously found that deletion of Med1 in cardiomyocytes deregulates more than 5000 genes and promotes acute heart failure and hypothesize Med1 deficiency disrupts enhancer-promoter coupling. more...

(Submitter supplied) We conducted chromatin immunoprecipitation followed by sequencing (ChIP-seq) and proximity ligation-assisted ChIP-seq (PLAC-seq) for enhancers and promoters (E-P) using left ventricular tissues from dilated cardiomyopathy (DCM) patients and non-heart failure (NF) donors. Differential active enhancer H3K27ac and promoter H3K4me3 regions were identified between NF and DCM. While the average read density (ARD) for H3K27ac is similar between NF and DCM, the ARD of H3K4me3 is significantly lower in DCM samples than in NF.Super-enhancer (SE) analysis revealed that 929 and 129 genes linked to NF- and DCM-specific SE, respectively, and three unique SE-associated genes between NF and DCM were identified.Moreover, the differential E-P interactions were observed in the known heart failure gene loci and are correlated with the gene expression levels. more...

(Submitter supplied) Regulatory DNA elements in the human genome play important roles in determining the transcriptional abundance and spatiotemporal gene expression. It is a mystery how chromatin marks in regulatory elements are modulated to establish cell type-specific gene expression. Here we profiled a variety of epigenetic marks in the regulatory elements using massive ChIP-seq (n=84). We uncovered two classes of regulatory elements: Class I was identified with ubiquitous enhancer (H3K4me1) and promoter (H3K4me3) marks in all cell types, whereas Class II was enriched with H3K4me1 and H3K4me3 in a cell type-specific manner. more...

(Submitter supplied) Heart failure (HF) is driven via interplay between master regulatory transcription factors and dynamic alterations in chromatin structure. While pathologic gene transactivation in this context is known to be associated with recruitment of histone acetyl-transferases and local chromatin hyperacetylation, the role of epigenetic reader proteins in cardiac biology is unknown. We therefore undertook a first study of acetyl-lysine reader proteins, or bromodomains, in HF. more...

(Submitter supplied) Heart failure is driven by the interplay between master regulatory transcription factors and dynamic alterations in chromatin structure. Coordinate activation of developmental, inflammatory, fibrotic and growth regulators underlies the hallmark phenotypes of pathologic cardiac hypertrophy and contractile failure. While transactivation in this context is known to be associated with recruitment of histone acetyl-transferase enzymes and local chromatin hyperacetylation, the role of epigenetic reader proteins in cardiac biology is unknown. more...
