Cyclic Adenosine Monophosphate (CAMP) and Cyclic Guanosine Monophosphate (CGMP)

Abstract Human physiology is highly dependent on a well-coordinated system of communication between cells. A multitude of external signals, including hormones, neurotransmitters, and other molecules, interact with cells via specific cell-surface receptors.

Distribution of Cyclic Adenosine Monophosphate in Rat Brain

Archives of Neurology, 1971
Cyclic 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 Production by Embryonic Chick Cells

Science, 1978
Cells dissociated from 1-day-old chick embryos produce a pulse of cyclic adenosine monophosphate (cyclic AMP) when stimulated with cyclic AMP. There is a stimulus threshold concentration of about 10 -8 molar cyclic AMP and an upper limit, above which the response is suppressed, of about 6 × 10 -6

CYCLIC ADENOSINE MONOPHOSPHATE, VENTRICULAR FIBRILLATION, AND ANTIARRHYTHMIC DRUGS

The Lancet, 1976
It is proposed that the development of ventricular fibrillation in the context of ischaemic heart-disease and myocardial infarction can be related to accumulation of cyclic adenosine 3',5' monophosphate (A.M.P.) in the ischaemic zone. The known electrophysiological and metabolic actions of cyclic A.M.P.

Parathyroid Function And Urinary Cyclic 3‘5’ Adenosine Monophosphate

Acta Clinica Belgica, 1975
SummaryPatients with hypercalcemie primary hyperparathyroidism excrete more cyclic AMP than normal suhjects: 8.27 ± 0.19 μmoles/24 hr or 9.03 ± 0.92 μmoles/g creatinine.The excretion in hypoparathyroidism is lower than in normal volunteers: 3.07±0.30 μmoles/24 hr or 2.86 ± 0.36 μmoles/g creatinine.Patients with hypercalcemia of non-parathyroid origin ...

Prostaglandin E2, cyclic adenosine monophosphate and morphine analgesia

Brain Research, 1977
Intravenous administration of prostaglandin E2 (PGE2) to mice results in a significant distribution of PGE2 into the brain and an elevation of cyclic adenosine monophosphate (cAMP) in the midhindbrain and corpus striatum. Neither acute morphine administration nor morphine tolerance alters this response.

Cyclic adenosine monophosphate and human gastric acid secretion

The American Journal of Digestive Diseases, 1977
This report concerns gastric juice, plasma, and urinary levels of adenosine 3',5'-monophosphate (cAMP) in 27 subjects undergoing routine gastric analysis under maximum stimulation with betazole or pentagastrin. Cyclic AMP was measured by sensitive and specific radioimmunoassay. No increase in concentration of cAMP was noted in gastric juice, plasma, or

Cyclic adenosine 3′,5′-monophosphate in human lung

Biochimica et Biophysica Acta (BBA) - General Subjects, 1971
Abstract Cyclic[ 14 C]adenosine 3′,5′-monophosphate (cyclic AMP) in human lung fragments has been measured by an isotopic method. It was found that aminophylline transiently increased cyclic[ 14 C]AMP by 100% in doses above 1 mM. β-Adrenergic agents, epinephrine and isoproterenol, increased cyclic [ 14 C]AMP by greater than 1000% through at least 10 ...

Cell Communication, Calcium Ion, and Cyclic Adenosine Monophosphate

Science, 1970
The hypothesis advanced in this article requires further validation. Undoubtedly it will require modification as our knowledge of biochemical control increases. Nevertheless, it should prove useful in focusing attention on the apparent similarity in the response of a large number of specific cell types to particular stimuli.
