Origin of Cyclic Adenosine Monophosphate in Saliva
Journal of Dental Research, 1975The level of cyclic adenosine monophosphate (AMP) in duct saliva from the dog submandibular gland was increased after cyclic AMP was administered intravenously in vivo. Isoproterenol increased the level of cyclic AMP in plasma and saliva in vivo and in salivary gland slices in vitro, but increased the level only slightly in saliva in a perfused dog ...

Cyclic Adenosine Monophosphate: Function in Photoreceptors
Science, 1971Inactivation of adenylate cyclase in outer segments of retinal photoreceptor cells is proportional to the bleaching of rhodopsin. Membranes of the outer segments also contain a particulate, light-insensitive phosphodiesterase of high specific activity. In electrophysiological experiments, application of cyclic adenosine monophosphate along

Cyclic adenosine monophosphate and the development of polysphondylium
Journal of Cell Science, 1976ABSTRACT Centre formation in Polysphondylium violaceum is delayed for 2 h on buffered agar containing 10−3 M c-AMP, and for up to 22 h on unbuffered agar with the same c-AMP concentration. With ambient c-AMP concentrations as low as 10−8 M, P. pallidum forms numerous, small, atypical aggregates which do not fruit.

Distribution of Cyclic Adenosine Monophosphate in Rat Brain
Archives of Neurology, 1971Cyclic 3',5'-adenosine monophosphate (AMP) was assayed by converting it enzymatically to adenosine triphosphate (ATP) with phosphodiesterase, myokinase, and pyruvate kinase. Adenosine triphosphate was measured in a liquid scintillation spectrometer from the photons emitted when ATP serves as a substrate of the firefly luciferin-luciferase system.

Cyclic Adenosine Monophosphate as a Mediator of Hormone Action
New England Journal of Medicine, 1971ACCORDING to the classic definition, hormones are substances that are secreted by certain tissues and are carried by the circulation to other tissues, where their metabolic effects appear.

Cyclic Adenosine Monophosphate and Hypertension in Rats
Science, 1973Aortas from spontaneously hypertensive and stress hypertensive rats contained significantly lower intracellular concentrations of cyclic adenosine monophosphate than did their respective controls. Adenylate cyclase activity was normal but was less responsive to stimulation, while phosphodiesterase activity (especially the low Michaelis-Menten constant ...

Cyclic Adenosine Monophosphate Stimulation of Axonal Elongation
Science, 1972Elevated concentrations of adenosine 3′,5′-monophosphate induce a variety of cell movements. The role of adenosine 3′,5′-monophosphate in promoting those movements associated with growth prompted our study of in vitro microtubule-dependent axonal elongation.

Studies of the cyclic adenosine monophosphate chemoreceptor ofParamecium
The Journal of Membrane Biology, 1991A doublet of proteins (approximately 48,000 Mr) from the Paramecium cell body membrane fits several criteria for the external cAMP chemoreceptor. These criteria include: (i) selective elution from a cAMP affinity column, matching a specificity that could be predicted from the behavioral response and whole-cell binding; (ii) binding to wheat germ ...

Modulation of Synapse Formation by Cyclic Adenosine Monophosphate
Science, 1983Synapses between neuroblastoma-hybrid cells and myotubes exhibit a high degree of plasticity. Increase of cyclic adenosine monophosphate (AMP) levels of the hybrid cells for several days results in the appearance of functional voltage-sensitive Ca2+ channels, which are required for evoked secretion of acetylcholine.

Effects of adenosine 5′-monophosphate and adenosine 3′,5′-cyclic monophosphate on l cells
Journal of Cell Science, 1975ABSTRACT The adenine nucleotides, 5′-AMP and 3′5′-cyclic AMP block L cells in the S-phase of the cell cycle. The intracellular level of cyclic AMP is reduced after incubation of cells with 5′-AMP, and rates of uridine transport are increased after incubation with either 5′-AMP or cyclic AMP.
