Intracoronary adenovirus-mediated delivery and overexpression of the beta(2)-adrenergic receptor in the heart : prospects for molecular ventricular assistance.
(Circulation, 2000-02-01)
BACKGROUND: Genetic modulation of ventricular function may offer a novel therapeutic
strategy for patients with congestive heart failure. Myocardial overexpression of
beta(2)-adrenergic receptors (beta(2)ARs) has been shown ...
The CO/HO system reverses inhibition of mitochondrial biogenesis and prevents murine doxorubicin cardiomyopathy.
(J Clin Invest, 2007-12)
The clinical utility of anthracycline anticancer agents, especially doxorubicin, is
limited by a progressive toxic cardiomyopathy linked to mitochondrial damage and cardiomyocyte
apoptosis. Here we demonstrate that ...
Beta-arrestin-mediated beta1-adrenergic receptor transactivation of the EGFR confers cardioprotection.
(J Clin Invest, 2007-09)
Deleterious effects on the heart from chronic stimulation of beta-adrenergic receptors
(betaARs), members of the 7 transmembrane receptor family, have classically been shown
to result from Gs-dependent adenylyl ...
Level of beta-adrenergic receptor kinase 1 inhibition determines degree of cardiac dysfunction after chronic pressure overload-induced heart failure.
(Circulation, 2005-02-08)
BACKGROUND: Heart failure is characterized by abnormalities in beta-adrenergic receptor
(betaAR) signaling, including increased level of myocardial betaAR kinase 1 (betaARK1).
Our previous studies have shown that inhibition ...
Augmentation of cardiac contractility mediated by the human beta(3)-adrenergic receptor overexpressed in the hearts of transgenic mice.
(Circulation, 2001-11-13)
BACKGROUND: Stimulation of beta(1)- and beta(2)-adrenergic receptors (ARs) in the
heart results in positive inotropy. In contrast, it has been reported that the beta(3)AR
is also expressed in the human heart and that its ...
Preservation of myocardial beta-adrenergic receptor signaling delays the development of heart failure after myocardial infarction.
(Proc Natl Acad Sci U S A, 2000-05-09)
When the heart fails, there is often a constellation of biochemical alterations of
the beta-adrenergic receptor (betaAR) signaling system, leading to the loss of cardiac
inotropic reserve. betaAR down-regulation and functional ...
Cardiac beta ARK1 inhibition prolongs survival and augments beta blocker therapy in a mouse model of severe heart failure.
(Proc Natl Acad Sci U S A, 2001-05-08)
Chronic human heart failure is characterized by abnormalities in beta-adrenergic receptor
(betaAR) signaling, including increased levels of betaAR kinase 1 (betaARK1), which
seems critical to the pathogenesis of the disease. ...
Regulation of G protein-coupled receptor signaling by scaffold proteins.
(Circ Res, 2002-10-18)
The actions of many hormones and neurotransmitters are mediated through stimulation
of G protein-coupled receptors. A primary mechanism by which these receptors exert
effects inside the cell is by association with heterotrimeric ...
Hybrid transgenic mice reveal in vivo specificity of G protein-coupled receptor kinases in the heart.
(Circ Res, 2000-01-07)
G protein-coupled receptor kinases (GRKs) phosphorylate activated G protein-coupled
receptors, including alpha(1B)-adrenergic receptors (ARs), resulting in desensitization.
In vivo analysis of GRK substrate selectivity has ...
Alterations in cardiac adrenergic signaling and calcium cycling differentially affect the progression of cardiomyopathy.
(J Clin Invest, 2001-04)
The medical treatment of chronic heart failure has undergone a dramatic transition
in the past decade. Short-term approaches for altering hemodynamics have given way
to long-term, reparative strategies, including beta-adrenergic ...
