Outline of Final Research Achievements

We analyzed epigenomic regulation of cardiomyocyte differentiation and heart failure. Genome-wide enhancer analysis revealed that β-catenin, which is activated by Wnt signaling upon differentiation, forms a complex with epigenomic regulators to activate mesodermal enhancers and provokes the down-stream gene program. Through integrative analysis of single-cell transcriptomes and epigenomes, we also unveiled that transcription factors which are induced upon pressure overload activates enhancers regulating the heart failure gene program. These results indicate that the epigenome regulates cardiomyocyte differentiation and failure.
