Colforsin 61-70 adrenoceptor beta 2 Homo sapiens 16-34 14722251-5 2004 Epinephrine, prostaglandin E1, and forskolin at maximum concentrations stimulated phosphorylation of the beta2AR PKA site (Ser262) by 4-fold, whereas PMA stimulated it by 2-fold. Colforsin 35-44 adrenoceptor beta 2 Homo sapiens 105-112 16873402-4 2006 beta(2)AR stimulation increased l-arginine transport, as did cyclic AMP elevation with either forskolin or dibutyryl cyclic AMP, and this increase was inhibitable by N-ethylmaleimide. Colforsin 94-103 adrenoceptor beta 2 Homo sapiens 0-9 14662724-11 2004 The desensitisation induced by long-term treatments with salmeterol and formoterol was specific for beta(2)-adrenoceptor-mediated inhibition of histamine release as the inhibitory effects of alternative cAMP-elevating compounds, prostaglandin E(2), a receptor-mediated activator of adenylate cyclase, and forskolin, a direct activator of adenylate cyclase, were unaffected by desensitising treatments. Colforsin 305-314 adrenoceptor beta 2 Homo sapiens 100-120 21225244-7 2011 A 5-min treatment with NAD decreased forskolin-stimulated phosphorylation at the beta(2)AR PKA site Ser 262 while a 24-h treatment with NAD increased it. Colforsin 37-46 adrenoceptor beta 2 Homo sapiens 81-90 14758043-0 2004 Influence of receptor number on the cAMP response to forskolin in Chinese hamster ovary cells transfected with human beta2-adrenoceptor. Colforsin 53-62 adrenoceptor beta 2 Homo sapiens 117-135 9698608-5 1998 Acute heterologous beta2AR desensitization was characterized by an approximately 20% and 30% loss of maximal responsiveness to ISO challenge when cells were pretreated with forskolin and prostaglandin E2 (PGE2), respectively. Colforsin 173-182 adrenoceptor beta 2 Homo sapiens 19-26 9295336-9 1997 The two strongest agonists, epinephrine and fenoterol, provoked 11-13-fold increases in the level of betaAR phosphorylation after just 1 min, whereas the weak agonists dobutamine and ephedrine caused only 3-4-fold increases, similar to levels induced by cAMP-dependent protein kinase activation with forskolin. Colforsin 300-309 adrenoceptor beta 2 Homo sapiens 101-107 2845534-3 1988 The addition of 10 microM forskolin to 50 microM isoproterenol potentiated isoproterenol induced beta 2 adrenoceptor desensitization as shown by further reduction in [3H]-DHA binding sites (decreased by 40% at 25 degrees C, 45% at 4 degrees C) and corresponding decrease in cyclic AMP responsiveness. Colforsin 26-35 adrenoceptor beta 2 Homo sapiens 97-116 7559596-7 1995 Further characterization of this phosphorylation, using either forskolin stimulation or phosphorylation site-deficient beta 2AR-Y326A mutants, demonstrated that the beta 2AR-Y326A mutant can be phosphorylated by cAMP-dependent protein kinase (PKA) but does not serve as a substrate for the beta-adrenergic receptor kinase 1 (beta ARK1). Colforsin 63-72 adrenoceptor beta 2 Homo sapiens 165-173 1325962-6 1992 Direct stimulation with forskolin resulted in greater cAMP production in the testosterone-treated myocytes compared to controls, thereby refuting the possibility that testosterone directly suppresses adenylyl cyclase activity at 24 h. These findings suggest that although both testosterone and hydrocortisone produce a twofold increase in beta 2-adrenergic receptor density in the DDT1 myocytes, beta 2-adrenergic receptors expressed in response to hydrocortisone appear functional at 24 h resulting in increased cAMP production, whereas those expressed in response to testosterone require 48 h to demonstrate increased functional activity.
