in order to elucidate the relationship between cyclic amp and the ca2+-calmodulin system in the steroidogenic response to adrenocorticotropic hormone ( acth ) , the effects of calmodulin inhibitors ( trifluoperazine and w-7 ) on cortisol production and cellular cholesterol ester hydrolysis induced by acth or dibutyryl cyclic amp in bovine adrenocortical cells were examined in the absence of extracellular ca2+ .
