Restoring the regenerative capacity of myocardium, which presents shortly in the newborns but lost in adulthood, is one of the therapeutic options for myocardial repair post various insults. In this work, we performed the phosphoproteomic analysis on neonatal regenerative myocardium and explored the...

We have previously found that overexpression of CHF1/Hey2 in the myocardium prevents the development of phenylephrine-induced hypertrophy. To determine the role of CHF1/Hey2 in pressure overload hypertrophy, we performed ascending aortic banding on wild type and transgenic mice overexpressing CHF1/H...
In the current study we examined several proteomic- and RNA-Seq-based datasets of cardiac-enriched, cell-surface and membrane-associated proteins in human fetal and mouse neonatal ventricular cardiomyocytes. By integrating available microarray and tissue expression profiles along with MGI phenotypic...

Background: We have previously found that overexpression of CHF1/Hey2 in the myocardium prevents the development of phenylephrine-induced hypertrophy and promotes physiological hypertrophy in an aortic banding model. To identify transcriptional pathways regulated by CHF1/Hey2 in hypertrophy, we cult...
To identify the relevant targets of the selected miRNAs, we assessed global transcriptome changes by deep-sequencing total neonatal mouse cardiomyocyte RNA after transfection with hsa-miR-590-3p or hsa-miR-199a-3p Four condition experiment; one replicate per condition; mouse neonatal cardiomyocytes ...
Myocardial damage caused for example by cardiac ischemia leads to ventricular volume overload resulting in increased stretch of the remaining myocardium. In adult mammals, these changes trigger an adaptive cardiomyocyte hypertrophic response which, if the damage is extensive, will ultimately lead to...
In mammals, Wnt pathway is activated during both heart regeneration post-injury and disease. Our previous work described the role of nuclear Wnt effectors B-catenin and Transcription factor 7-like 2 (TCF7L2) in heart disease progression; revealing GATA4 as a Wnt-repressor in the healthy adult heart....
