    In vivo ventricular gene delivery of a beta-adrenergic receptor kinase inhibitor to the failing heart reverses cardiac dysfunction. 

    Emani, S; Glower, Donald D Jr; Koch, Walter J; Kypson, Alan P; Lefkowitz, Robert J; Lilly, R Eric; Shah, AS; ... (9 authors) (Circulation, 2001-03-06)
    BACKGROUND: Genetic manipulation to reverse molecular abnormalities associated with dysfunctional myocardium may provide novel treatment. This study aimed to determine the feasibility and functional consequences of in vivo ...

    Hybrid transgenic mice reveal in vivo specificity of G protein-coupled receptor kinases in the heart. 

    Benovic, JL; Duncan, SJ; Eckhart, AD; Koch, Walter J; Lefkowitz, Robert J; Penn, RB (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. 

    Bohlmeyer, T; Bristow, MR; Freeman, K; Iaccarino, Guido; Koch, Walter J; Kranias, EG; Lefkowitz, Robert J; ... (9 authors) (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 ...

    Dual modulation of cell survival and cell death by beta(2)-adrenergic signaling in adult mouse cardiac myocytes. 

    Kobilka, BK; Koch, Walter J; Lefkowitz, Robert J; Xiao, RP; Zheng, Ming; Zhu, WZ (Proc Natl Acad Sci U S A, 2001-02-13)
    The goal of this study was to determine whether beta(1)-adrenergic receptor (AR) and beta(2)-AR differ in regulating cardiomyocyte survival and apoptosis and, if so, to explore underlying mechanisms. One potential mechanism ...

    Preservation of myocardial beta-adrenergic receptor signaling delays the development of heart failure after myocardial infarction. 

    Glower, Donald D Jr; Hata, Jonathan Andrew; Koch, Walter J; Lefkowitz, Robert J; Shah, AS; White, DC (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. 

    Harding, VB; Jones, LR; Koch, Walter J; Lefkowitz, Robert J; Rockman, Howard A (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. ...

    Catecholamines, cardiac beta-adrenergic receptors, and heart failure. 

    Koch, Walter J; Lefkowitz, Robert J; Rockman, Howard A (Circulation, 2000-04-11)
    Thumbnail

    Level of beta-adrenergic receptor kinase 1 inhibition determines degree of cardiac dysfunction after chronic pressure overload-induced heart failure. 

    Koch, Walter J; Lefkowitz, Robert J; Naga Prasad, SV; Rockman, Howard A; Tachibana, H (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 ...

    Intracoronary adenovirus-mediated delivery and overexpression of the beta(2)-adrenergic receptor in the heart : prospects for molecular ventricular assistance. 

    Glower, Donald D Jr; Hata, Jonathan Andrew; Koch, Walter J; Kypson, Alan P; Lefkowitz, Robert J; Lilly, R Eric; Pippen, Anne; ... (10 authors) (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 ...
