This work investigates signaling pathways for adenosine and catecholamine agonists that stimulate sperm kinetic activity. We show that 2-chloro-2'-deoxyadenosine and isoproterenol robustly accelerate flagellar beat frequency with EC50s near 10 and 0.05 microM, respectively. The several-fold acceleration is maximal by 60 sec. Although extracellular Ca2+ is required for agonist action on the flagellar beat, agonist treatment does not elevate sperm cytosolic [Ca2+] but does increase cAMP content. Acceleration does not require the conventional transmembrane adenylyl cyclase ADCY3, since it persists in sperm of ADCY3 knockout mice and in wild-type sperm in the presence of the inhibitors of conventional adenylyl cyclases SQ-22536, MDL-12330A, or 2', 5'-dideoxyadenosine. In contrast, the acceleration by these agents is absent in sperm that lack the predominant atypical adenylyl cyclase, SACY. Responses to these agonists are also absent in sperm from mice lacking the sperm-specific Calpha2 catalytic subunit of protein kinase A (PRKACA). Agonist responses also are strongly suppressed in wild-type sperm by the protein kinase inhibitor H-89. These results show that adenosine and catecholamine analogs activate sperm motility by mechanisms that require extracellular Ca2+, the atypical sperm adenylyl cyclase, cAMP, and protein kinase A."xsd:string |
