Browse the Cardiac Epigenome

The Cardiac Epigenome Browser is a resource for cell-type specific cardiac chromatin interaction and epigenome data. The project is located at the Institute of experimental and clinical Pharmacology and Toxicology, University of Freiburg, and online accessible.

The heart is composed of different cell-types including cardiac myocytes, fibroblasts and endothelial cells. Their relative portion depends on disease and developmental stage. Gene regulation cells mainly depends on epigenetic mechanisms. Due to the highly cell-type specific nature of these mechanisms analysis of pure cell-types is essential. Within the restricted nuclear space, the DNA is compacted together with proteins (chromatin) in a highly structured manner. Chromatin interaction analysis by Hi-C-based methods gives insights into the hierarchically organization of the chromatin. This enables identification of interacting chromatin domains (TADs), active and inactive compartments (A/B compartments) and finally chromatin contact points like promoter enhancer contacts. These potential regulatory regions can further be characterized using specific chromatin marks and DNA methylation signatures.

The Cardiac Epigenome Browser allows visualization of chromatin interaction data together with various chromatin marks, DNA methylation and gene expression.
