β‐Agonist‐induced constitutive β2‐adrenergic receptor activity in bovine tracheal smooth muscle [PDF]

open access: yesBritish Journal of Pharmacology, 2000
According to the two state receptor model, the β2‐adrenergic receptor (β2‐AR) isomerizes between an inactive state and a constitutively active state, which couples to the stimulatory G‐protein in the absence of agonist. In bovine tracheal smooth muscle (BTSM), we investigated the effect of short and long term β2‐AR activation by fenoterol on ...

Beta(2)-adrenergic receptor (ADRB2) gene polymorphisms and risk of COPD exacerbations : the Rotterdam study [PDF]

open access: yes, 2019
The role of the beta(2)-adrenergic receptor (ADRB2) gene in patients with chronic obstructive pulmonary disease (COPD) is unclear. We investigated the association between ADRB2 variants and the risk of exacerbations in COPD patients treated with inhaled ...

Cannabinoid Receptor Involvement in Stress-Induced Cocaine Reinstatement: Potential Interaction with Noradrenergic Pathways [PDF]

open access: yes, 2012
This study examined the role of endocannabinoid signaling in stress-induced reinstatement of cocaine seeking and explored the interaction between noradrenergic and endocannabinergic systems in the process.

Temporal response of ectopic activity in guinea pig ventricular myocardium in response to isoproterenol and acetylcholine

open access: yesFrontiers in Physiology, 2015
Both beta adrenergic and muscarinic receptor stimulation independently potentiate arrhythmogenesis. However, the effect of simultaneous stimulation on arrhythmogenesis is not well known.

Comparison of antimuscarinic drugs to beta adrenergic agonists in overactive bladder: A literary review

open access: yesCurrent Urology, 2021
. Background:. The purpose of this study was to carry an extended literature review to compare antimuscarnics with beta adrenergic agonists (mirabegron) in treatment of overactive bladder. Materials and methods:.

Antithetic regulation by β-adrenergic receptors of Gq receptor signaling via phospholipase C underlies the airway β-agonist paradox [PDF]

open access: yesJournal of Clinical Investigation, 2003
beta-adrenergic receptors (betaARs) relax airway smooth muscle and bronchodilate, but chronic beta-agonist treatment in asthma causes increased sensitivity to airway constriction (hyperreactivity) and is associated with exacerbations. This paradox was explored using mice with ablated betaAR genes (betaAR-/-) and transgenic mice overexpressing airway ...

A selective alpha1D-adrenoreceptor antagonist inhibits human prostate cancer cell proliferation and motility "in vitro" [PDF]

open access: yes, 2016
The progression of prostate cancer (PC) to a metastatic hormone refractory disease is the major contributor to the overall cancer mortality in men, mainly because the conventional therapies are generally ineffective at this stage. Thus, other therapeutic

Expression of inwardly rectifying potassium channels (GIRKs) and beta-adrenergic regulation of breast cancer cell lines

open access: yesBMC Cancer, 2004
Background Previous research has indicated that at various organ sites there is a subset of adenocarcinomas that is regulated by beta-adrenergic and arachidonic acid-mediated signal transduction pathways.
