persistent stimulation with isoproterenol of the beta adrenergic receptor located in c6 glioma cell membranes results in a rapid rise in the cyclic amp content , an activation of soluble cyclic amp-dependent protein kinase , a translocation of catalytic subunits of the activated protein kinase to the nucleus and a delayed ( 3 -- 4 hr later ) increase of cyclic amp phosphodiesterase activity and beta-nerve growth factor content .
