Differential mechanisms of action of the trace amines octopamine, synephrine and tyramine on the porcine coronary and mesenteric artery [PDF]

open access: yes, 2019
Trace amines such as p-tyramine, p-octopamine and p-synephrine are found in low concentrations in animals and plants. Consumption of pre-workout supplements containing these plant-derived amines has been associated with cardiovascular side effects.

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 ...

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.

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 ...

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.

A Synergistic Antiobesity Effect by a Combination of Capsinoids and Cold Temperature Through Promoting Beige Adipocyte Biogenesis. [PDF]

open access: yes, 2016
Beige adipocytes emerge postnatally within the white adipose tissue in response to certain environmental cues, such as chronic cold exposure. Because of its highly recruitable nature and relevance to adult humans, beige adipocytes have gained much ...
