A Beta-Adrenergic Partial Agonist (Befunolol) Discriminates Two Different Affinity Sites

Agonist-specific alterations in receptor binding affinity associated with solubilization of turkey erythrocyte membrane beta adrenergic receptors.

Agonist-induced modulation of inverse agonist efficacy at the beta 2-adrenergic receptor.

Sustained stimulation of several G protein-coupled receptors is known to lead to a reduction in the signaling efficacy. This phenomenon, named agonist-induced desensitization, has been best studied for the beta 2-adrenergic receptor (AR) and is characterized by a decreased efficacy of beta-adrenergic agonists to stimulate the adenylyl cyclase activity. Recently, several beta-adrenergic ligands ...

Effects of Dietary Beta-Adrenergic Agonist, Terbutaline, on Carcass Characteristics and Blood Attributes in Japanese Quails (Coturnix coturnix japonica)

The effect of dietary Terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 Japanese quails was studied from 21 through 49 days of age. Dietary treatments included four levels of Terbutaline [0 (T0), 1 (T1), 3 (T3), and 5 (T5) mg/Kg of the diet]. Quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

Regulation of beta-adrenergic receptors and calcium channel agonist binding sites in cultured human embryonal smooth muscle cells.

Recent electrophysiological studies with cell membrane patches of cardiac myocytes and an electrically excitable cell line derived from rat pituitary tumor suggested that voltage activated calcium channels must be phosphorylated to respond to membrane depolarization (Armstrong and Eckert 1986; Trautwein and Kameyama 1986). In view of the "phosphorylation hypothesis" we investigated the adenylat...
