Heptahelical receptor signaling: beyond the G protein paradigm.
(J Cell Biol, 1999-05-31)
Bbeta-adrenergic receptor kinase-1 levels in catecholamine-induced myocardial hypertrophy: regulation by beta- but not alpha1-adrenergic stimulation.
(Hypertension, 1999-01)
Pressure overload ventricular hypertrophy is accompanied by dysfunctional beta-adrenergic
receptor signaling due to increased levels of the beta-adrenergic receptor kinase-1,
which phosphorylates and desensitizes beta-adrenergic ...
Enhancement of cardiac function after adenoviral-mediated in vivo intracoronary beta2-adrenergic receptor gene delivery.
(J Clin Invest, 1999-07)
Exogenous gene delivery to alter the function of the heart is a potential novel therapeutic
strategy for treatment of cardiovascular diseases such as heart failure (HF). Before
gene therapy approaches to alter cardiac function ...
Hetahelical receptor signaling: Beyond the G protein paradigm
(Journal of Cell Biology, 1999-05-31)
Relaxed negative selection in germinal centers and impaired affinity maturation in bcl-xL transgenic mice.
(J Exp Med, 1999-08-02)
The role of apoptosis in affinity maturation was investigated by determining the affinity
of (4-hydroxy-3-nitrophenyl)acetyl (NP)-specific antibody-forming cells (AFCs) and
serum antibody in transgenic mice that overexpress ...
Nuclear import of Cdk/cyclin complexes: identification of distinct mechanisms for import of Cdk2/cyclin E and Cdc2/cyclin B1.
(J Cell Biol, 1999-01-25)
Reversible phosphorylation of nuclear proteins is required for both DNA replication
and entry into mitosis. Consequently, most cyclin-dependent kinase (Cdk)/cyclin complexes
are localized to the nucleus when active. Although ...
Identification of the endophilins (SH3p4/p8/p13) as novel binding partners for the beta1-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1999-10-26)
Several G-protein coupled receptors, such as the beta1-adrenergic receptor (beta1-AR),
contain polyproline motifs within their intracellular domains. Such motifs in other
proteins are known to mediate protein-protein interactions ...
In vivo inhibition of elevated myocardial beta-adrenergic receptor kinase activity in hybrid transgenic mice restores normal beta-adrenergic signaling and function.
(Circulation, 1999-08-10)
BACKGROUND: The clinical syndrome of heart failure (HF) is characterized by an impaired
cardiac beta-adrenergic receptor (betaAR) system, which is critical in the regulation
of myocardial function. Expression of the betaAR ...
Targeting Gbeta gamma signaling in arterial vascular smooth muscle proliferation: a novel strategy to limit restenosis.
(Proc Natl Acad Sci U S A, 1999-03-30)
Restenosis continues to be a major problem limiting the effectiveness of revascularization
procedures. To date, the roles of heterotrimeric G proteins in the triggering of pathological
vascular smooth muscle (VSM) ...
Coupling of beta2-adrenoceptor to Gi proteins and its physiological relevance in murine cardiac myocytes.
(Circ Res, 1999-01-08)
-Transgenic mouse models have been developed to manipulate beta-adrenergic receptor
(betaAR) signal transduction. Although several of these models have altered betaAR
subtypes, the specific functional sequelae of betaAR ...
