title: Implication of guanosine 3',5'-cyclic monophosphate, adenosine 3',5'-cyclic monophosphate, adenosine 5'-mono-, di- and triphosphate and fructose-2,6-bisphosphate in the regulation of the glycolytic pathway in hypoxic/anoxic mussel, Mytilus galloprovincialis.
abstract: The change in the content of cyclic GMP, cyclic AMP, ATP, ADP, AMP and fructose-2,6-bisphosphate that occurred in the mantle of the mussel Mytilus galloprovincialis Lmk when specimens of this mollusk were subjected to a hypoxia/anoxia situation were assessed. After the early 24 h in anaerobiosis, a clear decrease was observed in the ATP content, which remained close to that value for the rest of the time. AMP content doubled during the early 24 h in anaerobiosis and, from that time on, it remained close to that value. Fructose-2,6-bisphoshate and cyclic GMP showed a similar behavior. The levels of these compounds rose significantly during the early hours in anaerobiosis, and then fell to values similar to those of aerobiosis, remaining constant for the rest of the time. Neither ADP nor cAMP showed significant variations.
