| Authors: | I Harary F Hoover B Farley |
| Abstract: | Catecholamines and dibutyryl adenosine 3', 5'-monophosphate (dibutyryl cyclic AMP) increase the activity of myosin adenosine triphosphatase in cultured rat heart cells. Dichloroisoproterenol, an inhibitor of the beta receptor of the catecholamines, inhibits the action of the catecholamines but not of cyclic AMP. |
