Psychosomatics, 1972
• The history of research on various neurohumors that control behavior appears to be very cyclical; each decade having a favorite chemical mediator implicated in behavioral control and in psychotropic drug action. Before 1950 the focus was on acetylcholine as an important element in brain function, mainly because of its involvement in peripheral and ...

Cyclic AMP and cyclic GMP in hyperresponsiveness
Life Sciences, 1988Cyclic-AMP has been shown to cause a hyperresponse in blood pressure change in conjunction with norepinephrine in the anesthetized rat system. Recent experiments show that the antagonist to angiotensin II, Sar1-Thr8 angiotensin II, abolishes the hyperresponse produced by c-AMP.

Interdomain interaction of cyclic AMP receptor protein in the absence of cyclic AMP
Journal of Biochemistry, 2007Interdomain interaction of apo-cyclic AMP receptor protein (apo-CRP) was qualified using its isolated domains. The cAMP-binding domain was prepared by a limited proteolysis, while the DNA-binding domain was constructed as a recombinant protein. Three different regions making interdomain contacts in apo-CRP were identified by a sequence-specific ...

The measurement of cyclic GMP and cyclic AMP phosphodiesterases
Analytical Biochemistry, 1979Abstract Methods are described for measuring phosphodiesterases for cGMP and cAMP in the range of activity yielding 10 −12 to 10 −8 mol of product. The 5′-GMP formed is measured by conversion to GDP with guanylate kinase. Amounts of GDP greater than 10 −10 mol are measured directly with an enzyme system which results in stoichiometric oxidation of

Annual Review of Pharmacology, 1974
A chapter on "Cyclic AMP and Drug Action" has already been published in Annual Review of Pharmacology (1). In spite of its restrictive title, this paper covered most of the knowledge about the biochemical and biological effects of cAMP that was available in 1969.

The role of cyclic AMP and cyclic GMP in byssinosis
American Industrial Hygiene Association Journal, 1979The lungs of female guinea pigs, either untreated or previously sensitized with aqueous extracts of cotton dust (AECD) were perfused via the pulmonary artery with 0, 10-6, 10-5 or 10-4 g/mL of lyophilized AECD in Tyrodes solution. Pressure changes in the pulmonary artery were monitored during this period.

Cyclic AMP in Hypersensitivity Reactions
Allergy, 1979Phytohemagglutinin (PHA) was capable of inducing non‐cytotoxic histamine release from human leucocytes. In the presence of deuterium oxide (D2O), PHA caused significantly greater histamine release. Dibutyryl cyclic AMP id‐cAMP) could enhance the histamine release in the presence of D2O although it was an inhibitor of the release if used alone. However,

JAMA: The Journal of the American Medical Association, 1974
To the Editor.— Dr. Auerbach reports (227:326, 1974) on the topical use of dibutylated cyclic adenosine monophosphate (cyclic AMP) in patients with psoriasis, the rationale being to elevate the reduced levels of skin cyclic AMP in these people. He observed either no improvement or worsening of lesions and suggests several possible reasons for lack of ...

The occurrence of cyclic AMP in archaebacteria
Biochemical and Biophysical Research Communications, 1986Cyclic AMP was found in species representative of the three major groups of the archaebacteria. In Methanobacterium thermoautotrophicum starvation for H2 led to a significant increase in cellular cAMP. The findings suggest that the occurrence of cAMP antedates the divergence of the major kingdoms of biology; the observations also imply that cAMP ...
