Abstract

The effects of oxytocin and epinephrine on the adenyl cyclase activity of myometrial slices from pregnant rhesus monkeys (Macaca mulatta) near term were measured by the conversion of ATP-14C to cyclic AMP-14C. ATP was prelabeled by incubation with adenine-8-14C. In the presence of caffeine, oxytocin at 2.5 and 5.0 × 10-8M concentrations stimulated adenyl cyclase activity to the same extent. Epinephrine, 1 × 10-7M, also caused an increase in the adenyl cyclase activity in the presence of caffeine.
