A Common β1-Adrenergic Receptor Polymorphism Predicts Favorable Response to Rate-Control Therapy in Atrial Fibrillation.
Summary of "A Common β1-Adrenergic Receptor Polymorphism Predicts Favorable Response to Rate-Control Therapy in Atrial Fibrillation."
In this study, we evaluated the impact of 2 common β1-adrenergic receptor (β1-AR) polymorphisms (G389R and S49G) in response to ventricular rate control therapy in patients with atrial fibrillation (AF).

Medical and Biotech [MESH] Definitions
Receptors, Adrenergic, Beta-3
A subclass of beta-adrenergic receptors (RECEPTORS, ADRENERGIC, BETA). beta-3 Adrenergic receptors are the predominant beta-adrenergic receptor type expressed in white and brown ADIPOCYTES and are involved in modulating ENERGY METABOLISM and THERMOGENESIS.
Receptors, Interleukin-1 Type I
An interleukin-1 receptor subtype that is involved in signaling cellular responses to INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The binding of this receptor to its ligand causes its favorable interaction with INTERLEUKIN-1 RECEPTOR ACCESSORY PROTEIN and the formation of an activated receptor complex.
Peak Expiratory Flow Rate
Measurement of the maximum rate of airflow attained during a FORCED VITAL CAPACITY determination. Common abbreviations are PEFR and PFR.
G-protein-coupled Receptor Kinase 2
A ubiquitously expressed G-protein-coupled receptor kinase subtype that has specificity for the agonist-occupied form of BETA-ADRENERGIC RECEPTORS. It may play an essential role in regulating myocardial contractile response.
Maximal Expiratory Flow Rate
The airflow rate measured during the first liter expired after the first 200 ml have been exhausted during a FORCED VITAL CAPACITY determination. Common abbreviations are MEFR, FEF 200-1200, and FEF 0.2-1.2.
Astrocyte glucose metabolism functions to maintain brain activity in both normal and stress conditions. Dysregulation of astrocyte glucose metabolism relates to development of neuronal disease, such a...
AGAP2 is a multidomain Arf GAP (ADP ribosylation factor-directed GTPase-activating protein) that was shown to promote the fast-recycling of transferrin receptors. Here, we tested the hypothesis that A...
In many teleost fish, catecholamines activate a red blood cell (RBC) Na(+)/H(+) exchanger (βNHE), raising RBC intracellular pH to protect haemoglobin-O(2) loading. The present study tested the hypoth...
Autoimmune response against myocardial antigens is evident in numerous heart diseases. Both the induction of an autoimmune response and the pathogenesis of autoimmune heart diseases are not fully unde...
The in vivo role of TNF signaling in the genesis of β-adrenergic receptor (β-AR)-mediated cardiac hypertrophy is unknown. Wild-type (WT), TNF receptor 1 (TNFR1)-/- and TNFR2-/- mice were given isopr...
At present, there is some clinical data for different functional response to beta-blockers associated with beta-adrenergic receptor polymorphisms. But there has been no data reported, abou...
Hypoglycaemia unawareness is a common complication in patients with type 1 diabetes and with insulin-treated type 2 diabetes of long duration. The loss of autonomic symptoms to hypoglycemi...
OBJECTIVES: I. Determine the response in plasma norepinephrine concentration and plasma glycerol to the agonist (clonidine) and the antagonist (yohimbine) of the alpha-2 adrenergic recept...
Single nucleotide polymorphisms at codon 46 and 79 of the gene encoding for the ß2 adrenergic receptor (ß2AR) modify its pharmacological properties and may alter the response to ß2AR ag...
The adenosine receptor is known for its anti-inflammatory actions and could therefore be a potential target in the treatment of sepsis and septic shock. Stimulation of the adenosine recept...
