Description
Unlike human hearts, zebrafish hearts efficiently regenerate after injury. Regeneration is driven by the strong proliferation response of its cardiomyocytes to injury. In this study, we show that active telomerase is required for cardiomyocyte proliferation and full organ recovery, supporting the potential of telomerase therapy as a means of stimulating cell proliferation upon myocardial infarction. Overall design: Heart transcriptomes of WT and telomerase defective adult zebrafish animals were profiled by RNASeq, in control conditions and 3 days after heart cryoinjury.

Description
The functioning of a specific tissue depends on the expression pattern of the different genes. We used microarrays to compare gene expression across different murine tissues, to get a better understanding in the expression pattern and functioning of the different tissues. With this analysis, we were not only able to identify genes that were specifically expressed in a spicific tissue but, as important, we also identified genes that were specifically repressed in a tissue, compared to al the other analysed tissues.

Description
Lineage commitment during Embryonic Stem Cells (ESCs) differentiation is controlled not only by a gamut of transcription factors but also by epigenetic events, mainly histone deacetylation and promoter DNA methylation. Moreover, the DNA demethylation agent 5-Aza-2-deoxycytidine (AzadC) has been widely described in the literature as an effective chemical stimulus used to promote cardiomyogenic differentiation in various stem cell types; however, its toxicity and instability complicate its use. Thus, the purpose of this study was to examine the effects of zebularine, a stable and non-toxic DNA cytosine methylation inhibitor, on ESCs differentiation. Herein are the Affymetrix Expression data obtained from RNA of murine ESCs treated with zebularine.
