Ronald E. Weishaar. The action of epinephrine illustrates the principles by which cyclic AMP mediates hormone action. Cyclic AMP may regulate PTH secretion independent of other messengers, such as intracellular calcium and inositol phosphates, because elevation in cellular cAMP content is not accompanied by changes in intracellular levels of either of these agents. Cyclic AMP is degraded by the phosphodiesterase (PDE) family of enzymes (4, 5). Phosphodiesterase (PDE) enzymes degrade cyclic di-AMP to the linear molecule 5’-pApA (phosphadenylyl adenosine).

It is "cyclic" because two bonds between the phosphate group and the hydroxyl groups on the sugar create a little ring structure.

DOI: 10.1007/978-3-642-68111-0_1. Degradation. Regulation of cyclic AMP synthesis and degradation is modified in rat liver at late gestation. A large number of studies during the past 30 years have elucidated the fundamental role of cAMP in the cellular response to many hormones and neurotransmitters. It is an activator of cyclic AMP-dependent protein kinase, but resistant to degradation by cyclic AMP phosphodiesterase. The hormone causes an increase in blood pressure and the breakdown of glucose for energy. The influence of cyclic AMP on cartilage degradation was investigated by using phosphodiesterase inhibitors [theophylline and 3-isobutyl-1-methylxanthine (IBMX)], forskolin (which activates the catalytic subunit of adenylate cyclase) and cyclic AMP analogues (dibutyryl and 8-bromo). Published. Cyclic adenosine 3′,5′-monophosphate (cAMP) was the first identified second messenger. Formation and Degradation of Cyclic Nucleotides: An Overview. Because many PDE isoforms are targeted to subcellular … A follicular spike in cyclic AMP (cAMP) and its subsequent degradation to AMP promotes oocyte maturation and ovulation. In vitro matured (IVM) oocytes do not receive the cAMP increase that occurs in vivo, and artificial elevation of cAMP in IVM cumulus-oocyte complexes improves oocyte developmental potential. pApA is also involved in a feedback inhibition loop that limits GdpP gene-dependent c-di-AMP hydrolysis, leading to elevated c-di-AMP levels.. Regulation. A follicular spike in cyclic AMP (cAMP) and its subsequent degradation to AMP promotes oocyte maturation and ovulation. Cyclic AMP: A Second Messenger. It is a cyclic nucleotide, composed of a phosphate group, the sugar ribose, and adenine.
