In the present work we have been able to demonstrate the existence of some interrelationship between intracellular level of cAMP content and phenobarbital induction of delta-aminolevulinic acid synthase, ferrochelatase, and cytochrome P-450 biosynthesis in isolated rat hepatocytes. The increase of the level of intracellular cAMP produced by activators of adenylate cyclase, inhibitors of phosphodiesterase, or added cyclic nucleotides is reflected by an increase of the phenobarbital induction effect. The greater induction observed in hepatocytes of diabetic rats may be due to a higher level of the intracellular cAMP. The lack of potentiation of added cAMP in diabetic cells is mainly due to the fact that the maximum induction that could be attained is already achieved by the effect of the preexisting high level of the endogenous cAMP.
