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 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.

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.

Abstract Electrochromatography with carefully adjusted electrolyte solutions (0.003 M zinc acetate, 0.035 M citric acid, and 0.0148 M sodium citrate) at pH 3.8 is an effective technique for the separation of mixtures of phosphoric acid, adenosine monophosphate, adenosinc diphosphate, and adenosine triphosphate.

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.

Adenosine-5-monophosphate catabolism in frog liver
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19871. AMP catabolism in frog liver extract was found to proceed exclusively through the formation of IMP. Further metabolism of IMP is relatively slow. 2. Among the enzymes involved in AMP catabolism, AMP deaminase is most active and adenosine deaminase and AMP 5'-nucleotidase exhibit only 20 and 10% of AMP deaminase activity respectively.

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 ...

Effects of adenosine 5′-monophosphate on epidermal turnover
Archives of Dermatological Research, 2008The structure and function of the epidermis is maintained by cell renewal based on epidermal turnover. Epidermal turnover is delayed by aging, and it is thought that the delay of the epidermal turnover is a cause of aging alternation of skin. The epidermal turnover is related to the energy metabolism of epidermal basal cells. Adenosine 5'-triphosphate (

THE short survival of erythrocytes given by transfusion with stored donor blood is a problem of great current interest. The well-known steadily decreasing intensity of glycolysis in stored blood, despite excess of glucose, is easily explainable by a loss of adenosine triphosphate1. Gabrio et al.
