In cardiomyocytes, also CaMKII is inhibited and all three targeted enzymes are known to promote maladaptive cardiomyocyte hypertrophy. Here, in accordance with lack of Calcineurin inhibition in vivo, we did not observe a relevant anti-hypertrophic effect despite inhibition of Ras and CaMKII. However, cardiomyocyte-specific TBC1D10C overexpressing transgenic mice exhibited enhanced longevity. Ejection fraction and exercise capacity were enhanced in transgenic mice, but shortening of isolated cardiomyocytes was not increased. This suggests longevity resulted from enhanced cardiac performance but independent of cardiomyocyte contractile force. In further search for mechanisms, a transcriptome-wide analysis revealed expressional changes in several genes pertinent to control of heart rate (HR) including Hcn4, Scn10a, Sema3a and Cacna2d2. Indeed, telemetric holter recordings demonstrated slower atrial conduction and significantly lower HR. Pharmacological reduction of HR was previously demonstrated to enhance survival in mice. Thus, in addition to inhibition of stress signaling, TBC1D10C economizes generation of cardiac output via HR reduction, enhancing exercise capacity and survival. TBC1D10C may be a new target for HR reduction and longevity."],["dc.identifier.doi","10.1038/srep33853"],["dc.identifier.gro","3141617"],["dc.identifier.isi","000384478000002"],["dc.identifier.pmid","27667030"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13792"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/1678"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","2045-2322"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Enhanced cardiac TBC1D10C expression lowers heart rate and enhances exercise capacity and survival"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

We observed high Epo receptor (EPOR) expression in cardiac progenitor cells (CPCs). Therefore, we aimed to characterize these cells and elucidate their contribution to myocardial regeneration on Epo stimulation. High EPOR expression was detected during murine embryonic heart development followed by a marked decrease until adulthood. EPOR-positive cells in the adult heart were identified in a CPC-enriched cell population and showed coexpression of stem, mesenchymal, endothelial, and cardiomyogenic cell markers. We focused on the population coexpressing early (TBX5, NKX2.5) and definitive (myosin heavy chain [MHC], cardiac Troponin T [cTNT]) cardiomyocyte markers. Epo increased their proliferation and thus were designated as Epo-responsive MHC expressing cells (EMCs). In vitro, EMCs proliferated and partially differentiated toward cardiomyocyte-like cells. Repetitive Epo administration in mice with myocardial infarction (cumulative dose 4 IU/g) resulted in an increase in cardiac EMCs and cTNT-positive cells in the infarcted area. This was further accompanied by a significant preservation of cardiac function when compared with control mice. Our study characterized an EPO-responsive MHC-expressing cell population in the adult heart. Repetitive, moderate-dose Epo treatment enhanced the proliferation of EMCs resulting in preservation of post-ischemic cardiac function."],["dc.identifier.doi","10.1002/stem.1741"],["dc.identifier.gro","3142066"],["dc.identifier.isi","000341294500017"],["dc.identifier.pmid","24806289"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12130"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/4167"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/77"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | A02: Bedeutung des Phosphatase-Inhibitors-1 für die SR-spezifische Modulation der Beta- adrenozeptor-Signalkaskade"],["dc.relation","SFB 1002 | C04: Fibroblasten-Kardiomyozyten Interaktion im gesunden und erkrankten Herzen: Mechanismen und therapeutische Interventionen bei Kardiofibroblastopathien"],["dc.relation.eissn","1549-4918"],["dc.relation.issn","1066-5099"],["dc.relation.workinggroup","RG El-Armouche"],["dc.relation.workinggroup","RG Zelarayán-Behrend (Developmental Pharmacology)"],["dc.relation.workinggroup","RG Zimmermann (Engineered Human Myocardium)"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Erythropoietin Responsive Cardiomyogenic Cells Contribute to Heart Repair Post Myocardial Infarction"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
