Cyclic adenosine monophosphate (cAMP) production in avian theca cells during follicular maturation

Absence of antibodies stimulating H2-receptor mediated cyclic adenosine monophosphate (cAMP) production in peptic ulcer disease.

“cAMP Sponge”: A Buffer for Cyclic Adenosine 3′, 5′-Monophosphate

BACKGROUND While intracellular buffers are widely used to study calcium signaling, no such tool exists for the other major second messenger, cyclic AMP (cAMP). METHODS/PRINCIPAL FINDINGS Here we describe a genetically encoded buffer for cAMP based on the high-affinity cAMP-binding carboxy-terminus of the regulatory subunit RIbeta of protein kinase A (PKA). Addition of targeting sequences perm...

Formation of Cyclic Adenosine-S'-S'-monophosphate (cAMP) from Adenosine-5'-phosphosulfate (APS) in Chlamydomonas reinhardtii

Levels of cyclic adenosine monophosphate (cAMP) have been determined in the green alga Chlamydomonas reinhardtii strain CW 15. In the early exponential growth no cAMP was detected, however, in the middle of the exponential growth phase 2.4 pmol cAMP/mg protein were found and the cAMP level increased to 18.8 pmol/mg protein in the stationary phase. An enzyme fraction has been isolated from Chlam...

Enhancement of DNA synthesis of mouse myelogenous cells by cyclic adenosine 3',5'-monophosphate (cAMP).

To observe the possible role of cAMP on the DNA synthesis during specialization-division of myelogenous precursor cells, the authors observed the DNA and RNA synthesis of the cells by in vitro autoradiography. And it is concluded that cAMP or its dibutyryl derivative added to the media penetrated into myelogenous precursor cells and metamyelocytes of mice and enhanced the DNA synthetic capacity...
