(Submitter supplied) Backgound: Cardiac pressure overload, for example in patients with aortic stenosis, induces irreversible damage in the myocardium leading to cardiac dysfunction, cardiomyocyte hypertrophy and interstitial fibrosis. We therefore hypothesized that insufficient cardiac regeneration might contribute to the progression of pressure overload dependent disease. Here, we aimed to elucidate whether pressure overload in the regenerative stage shortly after birth could lead to a more adaptive cardiac response than in the non-regenerative stage in mice.nTAC in the non-regenerative stage induced cardiac dysfunction, myocardial fibrosis and cardiomyocyte hypertrophy. more...

(Submitter supplied) Background: Current mammalian model for heart regeneration research is limited in apex amputation or myocardium infarction, both of which are controversy. Moreover, RNAseq demonstrated there were a very limited set of differential expressed genes between sham and operation heart in the myocardium infarction model. Here we investigated whether pressure overload in the right ventricle(RV), a common phenomenon in congenital heart disease children, could be a better animal model for heart regeneration study when consider cardiomyocyte(CM) proliferation as the most important index. more...

(Submitter supplied) An important event in the pathogenesis of heart failure is the development of pathological cardiac hypertrophy. In cultured cardiac cardiomyocytes, the transcription factor Gata4 is required for agonist-induced cardiomyocyte hypertrophy. We hypothesized that in the intact organism Gata4 is an important regulator of postnatal heart function and of the hypertrophic response of the heart to pathological stress. more...

(Submitter supplied) The adult mammalian heart has limited capacity for regeneration following injury, whereas the neonatal heart can readily regenerate within a short period after birth. Neonatal heart regeneration is orchestrated by multiple cell types intrinsic to the heart, as well as immune cells that infiltrate the heart after injury. To elucidate the transcriptional responses of the different cellular components of the mouse heart following injury, we performed single cell RNA-sequencing on neonatal hearts at various time points following myocardial infarction, and coupled the results with bulk tissue RNA-sequencing data collected at the same time points. more...

(Submitter supplied) Background: Discovering determinants of cardiomyocyte maturity will be critical to understanding the maintenance of differentiated states and potentially reawakening endogenous regenerative programs in adult mammalian hearts as a therapeutic strategy. Recent evidence has suggested that forced dedifferentiation paired with oncogene expression is sufficient to drive cardiac regeneration. However, elucidation of endogenous developmental determinants of the switch between regenerative and mature cardiomyocyte cell states is necessary for optimal design of regenerative approaches for heart disease. more...

(Submitter supplied) Myocardial infarction (MI) leads to cardiomyocyte death, which triggers an immune response that clears debris and restores tissue integrity. In the adult heart, the immune system facilitates scar formation, which repairs the damaged myocardium but compromises cardiac function. In neonatal mice, the heart can regenerate fully without scarring following MI; however, this regenerative capacity is lost by P7. more...

(Submitter supplied) Cellular redox control is maintained by generation of reactive oxygen/nitrogen species balanced by activation of antioxidative pathways. Disruption of redox balance leads to oxidative stress, a central causative event in numerous diseases including heart failure. Redox control in the heart exposed to hemodynamic stress, however, remains to be fully elucidated. Here, we show that production of cardiomyocyte NADPH (nicotinamide adenine dinucleotide phosphate), a key factor in redox regulation, is decreased in pressure overload-induced heart failure. more...
