Differential expression of skeletal muscle genes following administration of clenbuterol to exercised horses. [PDF]
BackgroundClenbuterol, a beta2-adrenergic receptor agonist, is used therapeutically to treat respiratory conditions in the horse. However, by virtue of its mechanism of action it has been suggested that clenbuterol may also have repartitioning affects in

Mechanism of beta-adrenergic receptor kinase activation by G proteins
The beta-adrenergic receptor kinase (beta-ARK) specifically phosphorylates the activated form of various G protein-coupled receptors such as the beta 2-adrenergic receptor (beta 2-AR). Recently, G protein beta gamma subunits have been demonstrated to activate beta-ARK-mediated receptor phosphorylation.

Genetically Encoded Biosensors Reveal PKA Hyperphosphorylation on the Myofilaments in Rabbit Heart Failure [PDF]
RATIONALE: In heart failure, myofilament proteins display abnormal phosphorylation, which contributes to contractile dysfunction. The mechanisms underlying the dysregulation of protein phosphorylation on myofilaments is not clear.

Receptor-specific or homologous desensitization of beta 2-adrenergic receptors is thought to be effected via phosphorylation of the receptor by the beta-adrenergic receptor kinase (beta ARK), followed by binding of beta-arrestin. We have generated stably transfected Chinese hamster ovary cell lines overexpressing either of the two regulatory proteins ...

The β-Adrenergic Receptor Is a Substrate for the Insulin Receptor Tyrosine Kinase [PDF]
G-protein-linked receptors and intrinsic tyrosine-kinase growth receptors represent two prominent modalities in cell signaling. Cross-regulation among members of both receptor superfamilies has been reported, including the counter-regulatory effects of insulin on beta-adrenergic catecholamine action.

Adverse Effects on beta-Adrenergic Receptor Coupling: Ischemic Postconditioning Failed to Preserve Long-Term Cardiac Function [PDF]
BACKGROUND: Ischemic preconditioning (IPC) and ischemic postconditioning (IPoC) are currently among the most efficient strategies protecting the heart against ischemia/reperfusion injury.

Nitric oxide-dependent activation of CaMKII increases diastolic sarcoplasmic reticulum calcium release in cardiac myocytes in response to adrenergic stimulation. [PDF]
Spontaneous calcium waves in cardiac myocytes are caused by diastolic sarcoplasmic reticulum release (SR Ca(2+) leak) through ryanodine receptors.

The β-Adrenergic Receptor Kinase (GRK2) Is Regulated by Phospholipids [PDF]
The beta-adrenergic receptor kinase (beta ARK) is a member of growing family of G protein coupled receptor kinases (GRKs). beta ARK and other members of the GRK family play a role in the mechanism of agonist-specific desensitization by virtue of their ability to phosphorylate G protein-coupled receptors in an agonist-dependent manner.

Multidisciplinary Consideration of Potential Pathophysiologic Mechanisms of Paradoxical Erythema with Topical Brimonidine Therapy. [PDF]
Rosacea is a chronic inflammatory disease with transient and non-transient redness as key characteristics. Brimonidine is a selective α2-adrenergic receptor (AR) agonist approved for persistent facial erythema of rosacea based on significant efficacy and

The heartbreak of depression: 'Psycho-cardiac' coupling in myocardial infarction [PDF]
Ample evidence identifies strong links between major depressive disorder (MDD) and both risk of ischemic or coronary heart disease (CHD) and resultant morbidity and mortality. The molecular mechanistic bases of these linkages are poorly defined. Systemic
