Hormonal Inhibition of Adenylate Cyclase
Human platelet membranes contain a2 adrenergic receptors which mediate the guanine nucleotide-dependent inhibition of adenylate cyclase induced by epinephrine. Previous investigations have provided insight into the mechanisms of adenylate cyclase stimulation by studying hormone-induced release of radiolabeled guanine nucleotides from membranes preincubated with the nucleotides. In the present s...
متن کاملHormonal regulation of adenylate cyclase in the stria vascularis of the mouse.
The adenylate cyclase complex is a ubiquitous 'second-messenger' system mediating the actions of hormones and neurotransmitters. Its presence but not its physiological control and function had previously been established in the cochlea. In this study, the hormonal stimulation of adenylate cyclase activity of the stria vascularis of the CBA mouse was characterized. In the presence of the regulat...
متن کاملE VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...
متن کاملAdenylate cyclase from Brevibacterium liquefaciens. III. In situ regulation of adenylate cyclase by pyruvate.
In the presence of DL-alanine intracellular cyclic AMP in nonproliferating cells of Brevibacterium liquefaciens increased rapidly to the maximum level of approximately 180 muM, and extracellular cyclic AMP increased to 100 muM within 4 hr at 25 degrees . Adenylate cyclase (EC 4.6.1.1) induction was not observed during this incubation. The concentration of pyruvate in the total culture increased...
متن کاملRegulation of neuronal pituitary adenylate cyclase-activating polypeptide expression during culture of guinea-pig cardiac ganglia.
The trophic neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) increases in many different neuron types following injury; a response postulated to support cell survival and regeneration. In acutely isolated cardiac ganglia, approximately 1% of the cardiac neurons exhibited PACAP immunoreactivity whereas after 72 h in culture, approximately 25% of the neurons were PACAP immu...
