(Submitter supplied) Deciphering the genetic and epigenetic regulation of cardiomyocyte proliferation in organisms capable of robust cardiac renewal represents an attractive inroad towards regenerating the human heart. In the highly regenerative zebrafish heart, cardiomyocytes near the wound edge undergo dramatic changes in gene expression concomitant with sarcomere disassembly, loss of cell-cell adhesion, and detachment from the extracellular matrix (ECM), which leaves them poised to divide and give rise to new muscle cells that colonize the wound. more...

(Submitter supplied) We identify the global transcriptional changes that occur between homeostatic and proliferative cardiomyocytes in the zebrafish heart and uncover an essential role for H3K27me3 deposition in facilitating successful myocardial regeneration. Specifically, we learned that cardiomyocyte proliferation is accompanied by downregulation of sarcomeric and cytoskeletal components and upregulation of the polycomb methylase Ezh2. more...

(Submitter supplied) Super-enhancers (SEs) are key transcriptional drivers of cellular, developmental and disease states in mammals, yet the conservational and regulatory features of these enhancer elements in non-mammalian vertebrates are unknown. To define SEs in zebrafish and enable sequence and functional comparisons to mouse and human SEs, we used genome-wide histone H3 lysine 27 acetylation (H3K27ac) occupancy as a primary SE delineator. more...

(Submitter supplied) The epicardium is a mesothelial tissue layer that envelops the heart. Cardiac injury activates dynamic gene expression programs in epicardial tissue, which in the case of zebrafish enables subsequent regeneration through paracrine and vascularizing effects. To identify tissue regeneration enhancer elements (TREEs) that control injury-induced epicardial gene expression during heart regeneration, we profiled transcriptomes and chromatin accessibility in epicardial cells purified from regenerating zebrafish hearts. more...

(Submitter supplied) Early zebrafish embryo development proceeds first from a maternally transcribed and stored mRNAs, and zygotic gene activation (ZGA) is initiated at the mid-blastula transition (MBT; 1000-cell stage), 3.3 h post-fertilization. Very little is known on how the zygotic genome is programmed for transcriptional activation at the MBT. To start addressing this issue, we have mapped by ChIP-chip genome-wide promoter histone methylation (H3K4me3, H3K9me3, H3K27me3, H3K36me3) and RNA Pol II profiles before ZGA (256-cell stage; 2.5 hpf), during ZGA (MBT; 3.5 hpf)) and after ZGA (Post-MBT; 5.3 hpf) . more...
