Recent studies indicate a significant cross talk between β-AR signaling and CaMKII activation presenting CaMKII as a possible downstream mediator of detrimental β-AR signaling in HF. In this study, we investigated the effect of chronic β-AR blocker treatment on CaMKII activity in human and experimental HF. Methods and Results— Immunoblot analysis of myocardium from end-stage HF patients (n=12) and non-HF subjects undergoing cardiac surgery (n=12) treated with β-AR blockers revealed no difference in CaMKII activity when compared with non–β-AR blocker–treated patients. CaMKII activity was judged by analysis of CaMKII expression, autophosphorylation, and oxidation and by investigating the phosphorylation status of CaMKII downstream targets. To further evaluate these findings, CaMKIIδC transgenic mice were treated with the β1-AR blocker metoprolol (270 mg/kg d). Metoprolol significantly reduced transgene-associated mortality (n≥29; P<0.001), attenuated the development of cardiac hypertrophy (−14±6% heart weight/tibia length; P<0.05), and strongly reduced ventricular arrhythmias (−70±22% premature ventricular contractions; P<0.05). On a molecular level, metoprolol expectedly decreased protein kinase A–dependent phospholamban and ryanodine receptor 2 phosphorylation (−42±9% for P-phospholamban-S16 and −22±7% for P-ryanodine receptor 2-S2808; P<0.05). However, this was paralled neither by a reduction in CaMKII autophosphorylation, oxidation, and substrate binding nor a change in the phosphorylation of CaMKII downstream target proteins (n≥11). The lack of CaMKII modulation by β-AR blocker treatment was confirmed in healthy wild-type mice receiving metoprolol. Conclusions— Chronic β-AR blocker therapy in patients and in a mouse model of CaMKII-induced HF is not associated with a change in CaMKII activity. Thus, our data suggest that the molecular effects of β-AR blockers are not based on a modulation of CaMKII. Directly targeting CaMKII may, therefore, further improve HF therapy in addition to β-AR blockade."],["dc.identifier.doi","10.1161/CIRCHEARTFAILURE.117.003840"],["dc.identifier.pmid","28487342"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/77149"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/171"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.notes.status","final"],["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 | A03: Bedeutung CaMKII-abhängiger Mechanismen für die Arrhythmogenese bei Herzinsuffizienz"],["dc.relation.issn","1941-3289"],["dc.relation.issn","1941-3297"],["dc.relation.workinggroup","RG El-Armouche"],["dc.relation.workinggroup","RG L.

As the relative contribution of subtype α 1 -AR to cardiac stress responses remains poorly investigated, we subjected mice to either subcutaneous perfusion with the β-AR agonist isoprenaline (ISO, 30 mg/kg Ã— day) or to a combination of ISO and the stable α 1 -AR agonist phenylephrine (ISO/PE, 30 mg/kg Ã— day each). Telemetry analysis revealed similar hemodynamic responses under both ISO and ISO/PE treatment i.e., permanently increased heart rates and only transient decreases in mean blood pressure during the first 24 h. Echocardiography and single cell analysis after 1 week of exposure showed that ISO/PE-, but not ISO-treated animals established α 1 -AR-mediated inotropic responsiveness to acute adrenergic stimulation. Morphologically, additional PE perfusion limited concentric cardiomyocyte growth and enhanced cardiac collagen deposition during 7 days of treatment. Time-course analysis demonstrated a diverging development in transcriptional patterns at day 4 of treatment i.e., increased expression of selected marker genes Xirp2, Nppa, Tgfb1, Col1a1, Postn under chronic ISO/PE treatment which was either less pronounced or absent in the ISO group. Transcriptome analyses at day 4 via RNA sequencing demonstrated that additional PE treatment caused a marked upregulation of genes allocated to extracellular matrix and fiber organization along with a more pronounced downregulation of genes involved in metabolic processes, muscle adaptation and cardiac electrophysiology. Consistently, transcriptome changes under ISO/PE challenge more effectively recapitulated early transcriptional alterations in pressure overload-induced experimental heart failure and in human hypertrophic cardiomyopathy."],["dc.identifier.doi","10.1007/s00395-022-00920-z"],["dc.identifier.pii","920"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/105612"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-530"],["dc.relation.eissn","1435-1803"],["dc.relation.issn","0300-8428"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Chronic isoprenaline/phenylephrine vs. exclusive isoprenaline stimulation in mice: critical contribution of alpha1-adrenoceptors to early cardiac stress responses"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
