Project description:Ischemic cardiopathy is the leading cause of death in the world, for which efficient regenerative therapy is not currently available. In mammals, after a myocardial infarction episode, the damaged myocardium is replaced by scar tissue featuring collagen deposition and tissue remodelling with negligible cardiomyocyte proliferation. Zebrafish, in contrast, display an extensive regenerative capacity as they are able to restore completely lost cardiac tissue after partial ventricular amputation. Due to the lack of genetic lineage tracing evidence, it is not yet clear if new cardiomyocytes arise from existing contractile cells or from an uncharacterised set of progenitors cells. Nonetheless, several genes and molecules have been shown to participate in this process, some of them being cardiomyocyte mitogens in vitro. Though questions as what are the early signals that drive the regenerative response and what is the relative role of each cardiac cell in this process still need to be answered, the zebrafish is emerging as a very valuable tool to understand heart regeneration and devise strategies that may be of potential value to treat human cardiac disease. Here, we performed a genome-wide transcriptome profile analysis focusing on the early time points of zebrafish heart regeneration and compared our results with those of previously published data. Our analyses confirmed the differential expression of several transcripts, and identified additional genes the expression of which is differentially regulated during zebrafish heart regeneration. We validated the microarray data by conventional and/or quantitative RT-PCR. For a subset of these genes, their expression pattern was analyzed by in situ hybridization and shown to be upregulated in the regenerating area of the heart. The specific role of these new transcripts during zebrafish heart regeneration was further investigated ex vivo using primary cultures of zebrafish cardiomyocytes and/or epicardial cells. Our results offer new insights into the biology of heart regeneration in the zebrafish and, together with future experiments in mammals, may be of potential interest for clinical applications. In order to study zebrafish heart regeneration, a time course experiment was realized where amputated heart regenerating were compared to control heart. Samples in triplicate were extracted at 1, 3, 5 and 7 days post-amputation.

Project description:The prospect of repairing the heart after a myocardial infarction by promoting cardiomyocyte proliferation has gained momentum from studies showing the heart's regenerative ability in fish, amphibians and neonatal mammals. Despite evidence of varying cardiomyocyte proliferation rates among species, the molecular mechanisms driving cardiomyocyte cell cycle re-entry remain insufficiently understood. In this study, we employed spatial transcriptomics and identified high-mobility group AT-hook 1a (Hmga1a) as being upregulated in cardiomyocytes of the injury border zone in zebrafish, but not in mice. Through knock-out and cardiomyocyte-specific overexpression of hmga1a, we found that Hmga1a was required for zebrafish heart regeneration and sufficient to drive cardiomyocyte proliferation. In addition, a single injection of Hmga1 virus in injured mouse hearts resulted in increased border zone cardiomyocyte proliferation and improved heart function. Mechanistically, Hmga1 expression reduced repressive H3K27me3 histone modifications from developmentally-regulated genes and induced a border zone-like transcriptional program in adult cardiomyocytes. Our study demonstrates the value of interspecies comparisons by identifying Hmga1 as a critical driver of heart regeneration and highlights Hmga1 as a promising therapeutic candidate to improve cardiac repair after injury.

Project description:We used a cardiac-specific tamoxifen-dependent Gal4-ERT2/UAS model to achieve uniform but conditionally regulated expression of the oncogene HRASG12V in zebrafish cardiomyocytes. We found that the inhibition of TOR signaling using rapamycin treatment counteracts neoplasic growth. We analyse the transcriptome of neoplasic ventricles after exposure to DMSO and rapamycin and we applied bioinformatic analysis to determine common and distinctive molecular signatures of neoplasia versus regeneration of the heart.
