Treating rats with pertussis toxin (PTX) both elevated the adipocyte cAMP levels and impaired sensitivity and responsiveness to the antilipolytic effect of insulin in the presence of different beta-adrenergic agonists. However, in the presence of a fixed medium concentration of the degradable cAMP analogue, 8-bromo-cAMP, the effect of insulin was similar in PTX- and control cells. Elevating the cAMP levels in control cells either through different concentrations of the cAMP analogue or addition of adenosine deaminase impaired both insulin sensitivity and responsiveness to a similar extent as that seen in PTX-treated cells. The antilipolytic effect of insulin was exerted through the activation of the cGMP-inhibitable phosphodiesterase (cGI-PDE) as it was dose-dependently impaired by the specific cGI-PDE inhibitor OPC 3911. The results show the importance of the cellular cAMP levels in modulating insulin sensitivity and action. Gi plays a minor role, if any, for the signal transduction of the antilipolytic effect of insulin.
