Since both adenosine and cAMP affect sperm motility and metabolism, the authors have studied the mode of interaction of adenosine with the adenylate cyclase activity in either the presence or the ab...
In order to fertilize the egg, spermatozoa must go through the capacitation process where they experience Ca2+ uptake, increases in cyclic 3',5' adenosine monophosphate (cAMP) concentrations, supe...
Adenosine is able to alter intracellular cAMP levels and to affect the physiological functions of sperm. It also modulates FSH action through its Gi protein coupled receptors. Adenosine deaminase (A...
In the present study the effect of adenosine and adenosine analogues on rabbit isolated cavernosal smooth muscle has been evaluated in comparison with the effect of acetylcholine and electrical fi...
The aim of this study was to reveal a downstream part of the intracellular signaling that is mediated by cyclic adenosine monophosphate (cAMP)-dependent tyrosine kinases, including spleen tyrosine (...
Our previous observations of changes in the expression of cAMP-dependent genes and the cAMP-responsive element modulator (CREM) in rat testicular cells after spinal cord injury (SCI) implied abnor...
Ejaculated mammalian spermatozoa acquire competence to fertilize oocytes by a two-step process: capacitation followed by acrosome reaction. The biochemical and biophysical modifications occurring ...
Boar spermatozoa become agglutinated with one another at the head when their intracellular cyclic adenosine 3',5'-monophosphate (cAMP)-signaling cascades are activated in the head. The aim of the ...
When boar spermatozoa are incubated in a medium designed for in vitro fertilization, many of them become agglutinated at the acrosomes. We previously reported that bicarbonate and cyclic adenosine...
