title: Effect of insulin on metabolism of cyclic adenosine 3',5'-monophosphate by plasma cell tumor (MPC-11).
abstract: Addition of insulin to cultured mouse plasma tumor cells (MPC-11) increases the entry of tritiated cyclic adenosine 3',5'-monophosphate (3H-cAMP). No increase of entry of N6-O2-dibutyryl adenosine 3',5' cyclic monophosphate (DBcAMP), 5' adenosine monophosphate (5' AMP) or adenosine was noted in the presence of insulin. The stimulation of cAMP transport by insulin was concentration dependent and inactivated insulin had no effect on nucleotide transport. Intracellular radioactivity after transport of cAMP was largely 5'AMP, while most of the extracellular radioactivity remained as cAMP after incubation.
