Of particular significance was the development of chemical methods to convert highly polar signalling molecules
like cyclic nucleotides, inositol phosphates, and phosphoinositides to membrane - permeant, bioactivatable derivatives («prodrugs»)(Schultz 2003; Laketa et al. 2009, Laketa et al. 2014).
Symposia VI: Nitric Oxide and Sympatho - vagal Regulation Researchers will discuss
targeting cyclic nucleotides to rescue cardiac sympatho - vagal phenotypes in cardiovascular disease and the blood brain barrier and control of arterial pressure.
Vincent «Vinnie» Manganiello, a pioneering leader in the field
of cyclic nucleotide - mediated signaling, has died at age 76.
The increase, observed as early as 60 seconds after the addition of corticotropin - releasing factor, suggests that changes in the intracellular concentration of
the cyclic nucleotide coincide with or precede the secretion of adrenocorticotropic hormone in response to corticotropin - releasing factor.
They found what they were looking for on the CNGA3 gene, which encodes
a cyclic nucleotide channel and plays a key role in transducing visual signals.
These actions are specific for the sympathetic and parasympathetic neurotransmitters and for the two
cyclic nucleotides, as phenylephrine, tyramine, choline, adenosine 5» - monophosphate and guanosine 5» - monophosphate do not inodify lysosomal enzyme release.
Enzyme Release from Polymorphonuclear Leukocyte Lysosomes: Regulation by Autonomic Drugs and Cyclic Nucleotides
To be active, PKG I needs a small compound called cGMP,
a cyclic nucleotide, to bind to the R domain, which will then free the C domain to carry on phosphorylation of other proteins.
In both PKA and PKG, the R domains seem to contact each other through
their cyclic nucleotide binding domains.
Among the top hits was a variant adjacent to the gene for PDE10A,
a cyclic nucleotide phosphodiesterase involved in regulating smooth muscle contraction, including the muscles that surround the spleen.
