Dual modulation of cell survival and cell death by beta(2)-adrenergic signaling in adult mouse cardiac myocytes.
(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 ...
A magnificent time with the "magnificent seven" transmembrane spanning receptors.
(Circ Res, 2003-03-07)
Platelet-derived growth factor receptor association with Na(+)/H(+) exchanger regulatory factor potentiates receptor activity.
(Mol Cell Biol, 2000-11)
Platelet-derived growth factor (PDGF) is a potent mitogen for many cell types. The PDGF receptor (PDGFR) is a receptor tyrosine kinase that mediates the mitogenic effects of PDGF by binding to and/or phosphorylating a variety ...
The role of β-arrestins in the termination and transduction of G-protein-coupled receptor signals
(Journal of Cell Science, 2002-02-01)
β-arrestins are versatile adapter proteins that form complexes with most G-protein-coupled receptors (GPCRs) following agonist binding and phosphorylation of receptors by G-protein-coupled receptor kinases (GRKs). They play ...
Desensitization, internalization, and signaling functions of beta-arrestins demonstrated by RNA interference.
(Proc Natl Acad Sci U S A, 2003-02-18)
Beta-arrestins bind to activated G protein-coupled receptor kinase-phosphorylated receptors, which leads to their desensitization with respect to G proteins, internalization via clathrin-coated pits, and signaling via a ...
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. ...
Defective lymphocyte chemotaxis in beta-arrestin2- and GRK6-deficient mice.
(Proc Natl Acad Sci U S A, 2002-05-28)
Lymphocyte chemotaxis is a complex process by which cells move within tissues and across barriers such as vascular endothelium and is usually stimulated by chemokines such as stromal cell-derived factor-1 (CXCL12) acting ...
The kinase Grk2 regulates Nedd4/Nedd4-2-dependent control of epithelial Na+ channels.
(Proc Natl Acad Sci U S A, 2004-08-10)
Epithelial Na(+) channels mediate the transport of Na across epithelia in the kidney, gut, and lungs and are required for blood pressure regulation. They are inhibited by ubiquitin protein ligases, such as Nedd4 and Nedd4-2, ...
Anti–β1-adrenergic receptor antibodies and heart failure: causation, not just correlation
(Journal of Clinical Investigation, 2004-05-15)
