Abteilung fur Kardiologie, Georg August Universitat, Gottingen, Germany
Circulation 113:2724-32. 2006..However, there is evidence that BNP-mediated signaling may adversely influence cardiac remodeling, with further impairment of calcium homeostasis...
Mechanical load-dependent regulation of gene expression in monocrotaline-induced right ventricular hypertrophy in the ratHarald Kogler

Circ Res 93:230-7. 2003..Neuroendocrine factors, which equally affect both chambers, are not sufficient to alter the expression of Ca2+-cycling proteins...
Disproportionate enhancement of myocardial contractility by the xanthine oxidase inhibitor oxypurinol in failing rat myocardiumHarald Kogler
Institute of Molecular Cardiobiology, Johns Hopkins University, Baltimore, MD, USA
Cardiovasc Res 59:582-92. 2003..We examined whether this inotropic action is preserved or magnified in failing rat myocardium and whether the magnitude of this effect correlates with tissue xanthine-oxidoreductase (XOR) activity...
Elevated afterload, neuroendocrine stimulation, and human heart failure increase BNP levels and inhibit preload-dependent SERCA upregulationKarl Toischer
Abteilung Kardiologie und Pneumologie, Georg August Universitat, Robert Koch Strasse 40, Gottingen, Germany
Circ Heart Fail 1:265-71. 2008..In heart failure, brain-type natriuretic peptide (BNP) is elevated and the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) downregulated. We previously showed that preload-induced SERCA-upregulation is suppressed by exogenous BNP...
Local and systemic effects of angiotensin receptor blockade in an emphysema mouse modelTobias Raupach
Department of Cardiology and Pneumology, University Hospital Gottingen, Gottingen, Germany
Pulm Pharmacol Ther 24:215-20. 2011..This study examined the effects of an angiotensin II receptor blocker (ARB) on pulmonary and systemic manifestations of emphysema in a mouse model...
Hydroxyl radical-induced acute diastolic dysfunction is due to calcium overload via reverse-mode Na(+)-Ca(2+) exchangeOliver Zeitz
, Abteilung Kardiologie und Pneumologie, , Germany
Circ Res 90:988-95. 2002..Degradation of troponins appears to be species-dependent but does not contribute to the acute diastolic dysfunction...
Insulin-like growth factor-1 exerts Ca2+-dependent positive inotropic effects in failing human myocardiumDirk von Lewinski
Abteilung Kardiologie und Pneumologie, , Germany
Circ Res 92:169-76. 2003..The increased [Ca2+]i with IGF-1 originates from both enhanced L-type Ca2+ currents and enhanced Na+-H+ exchange-dependent reverse-mode Na+-Ca2+ exchange. These nongenomic functional effects of IGF-1 may be of clinical relevance...
Pressure overload and neurohumoral activation differentially affect the myocardial proteomePeter Schott
Department of Cardiology and Respiratory Care, Georg August University, Gottingen, Germany
Proteomics 5:1372-81. 2005..This study represents the first in-depth analysis of global proteome alterations in a controlled animal model of pressure overload-induced myocardial hypertrophy...
BNP controls early load-dependent regulation of SERCA through calcineurinKarl Toischer
Abteilung Kardiologie und Pneumologie, Georg August Universitat, Robert Koch Str 40, 37075, Gottingen, Germany
Basic Res Cardiol 105:795-804. 2010..This is followed by upregulation of natriuretic peptides with subsequent suppression of SERCA upregulation. Elevated natriuretic peptides may suppress SERCA expression by inhibition of calcineurin activity via activation of GC-A...
Celecoxib modulates hypertrophic signalling and prevents load-induced cardiac dysfunctionClaudius Jacobshagen
Department of Cardiology, University of Gottingen, Gottingen, Germany
Eur J Heart Fail 10:334-42. 2008..It reduces load-induced LV dilation, contractile dysfunction and mortality in vivo. This may have clinical implications for the prevention and treatment of maladaptive hypertrophy and its progression to HF in humans...
Myocardial adaptation of energy metabolism to elevated preload depends on calcineurin activity : a proteomic approachPeter Schott
Dept of Cardiology and Respiratory Care, Georg August University Gottingen, Gottingen, Germany
Basic Res Cardiol 103:232-43. 2008..This short-term adaptation to enhanced mechanical load appears to critically depend on calcineurin phosphatase activity...
Insulin causes [Ca2+]i-dependent and [Ca2+]i-independent positive inotropic effects in failing human myocardiumDirk von Lewinski
Abteilung Kardiologie und Pneumologie, , , Germany
Circulation 111:2588-95. 2005..These nongenomic functional effects of insulin may be of clinical relevance, eg, during insulin-glucose-potassium infusions...
Exercise intolerance and systemic manifestations of pulmonary emphysema in a mouse modelLars Lüthje
Kardiologie und Pneumologie, Georg August Universitat, Gottingen, Germany
Respir Res 10:7. 2009..Systemic effects of chronic obstructive pulmonary disease (COPD) significantly contribute to severity and mortality of the disease. We aimed to develop a COPD/emphysema model exhibiting systemic manifestations of the disease...
Negative inotropy of the gastric proton pump inhibitor pantoprazole in myocardium from humans and rabbits: evaluation of mechanismsWolfgang Schillinger
Herzzentrum, Kardiologie und Pneumologie, Georg August Universitaet Goettingen, Robert Koch Strasse 40, 37099 Goettingen, Germany
