Reinstatement of developmental stage-specific GATA4 enhancers controls the gene expression program in heart disease
Through integration of GATA4 genome-wide occupancy and RNA-seq dataset in embryonic conditional knockout heart, we identified a class of the master cardiac regulator GATA4 bound enhancers. With combinatorial assembly of chromatin signatures, we further refined that a unique type of fetal distal GATA4 enhancers enriched for H3K27ac, H3K4me1, but not for H3K4me3 and RNA polymerase II, are reinstated in adult hypertrophic heart. Overall design: Study Gata4 and histone modifications in E12.5, Adult, Banding and Sham, and to correlate to gene expression and heart function
