Adenylyl Cyclase Signaling in the Developing Chick Heart: The Deranging Effect of Antiarrhythmic Drugs

Figure 1

Adenylyl cyclase activity in the chick embryonic heart during ontogenesis. Basal (solid bars), isoprenaline-stimulated (hatched bars), and forskolin-stimulated (open bars) AC activity was monitored in myocardial membrane preparations from different stages of embryonic development. All values represent the mean ± SEM of three determinations measured in triplicate.
