Genome-wide chromatin state in non-failing and dilated cardiomyaphty human left ventricles [PLAC-seq]

Project description: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. Motif analysis identified known cardiac factors and possible novel players for DCM. We have established cistrome of four histone modifications and long-range chromatin interaction for enhancers and promoters in NF and DCM tissues. The differential histone modifications and E-P interactions were found in DCM, and these differences were associated with the gene expression level of a subset of disease-associated genes in human heart failure.

Methylome analysis reveals alterations in DNA methylation in the regulatory regions of left ventricle development genes in human dilated cardiomyopathy (methylation)

Project description:Alterations in DNA methylation and gene expression have been implicated in the development of human dilated cardiomyopathy (DCM). In this study, we analyzed DNA methylomes (Infinium 450K HumanMethylation BeadChip) and characterize differentially methylated probes between the left and right ventricles Illumina 450K array and HT-12 v4 array for the left, right ventricles

RNA sequencing of wildtype and homozygous titin A178D mouse left ventricle samples

Project description:Truncating variants in titin can cause dilated cardiomyopathy, however, the role of missense titin variants is less clear. In humans the heterozygous titin A178D variant is associated with dilated cardiomyopathy with left ventricular non-compaction. Using CRISPR-Cas9 mediated homology-directed repair the A178D titin variant was introduced into a mouse model. Homozygous A178D mice showed features of dilated cardiomyopathy. Total RNA was extracted from the left ventricles of WT and homozygous A178D littermate control mice and RNA-sequencing performed. Different patterns of gene expression were identified in wildtype and homozygous A178D left ventricles.
