the pge2-induced increase in the intracellular camp level appeared to activate preferentially the type i isoenzyme , inasmuch as the enzymatic activity of this type separated by the affinity chromatography of the cytosol of pge2-exposed cells was lower in the presence than in the absence of camp , whereas the type ii enzyme activity remained responsive to exogenously added camp .
