Phosphodiesterase 3B (PDE3B), is known to play an important role in acute insulin and cAMP-mediated regulation of lipid metabolism, and PDE4 are the main PDE types expressed in adipocytes. Here, we show that members of all PDE4 isoforms are expressed in 3T3-L1 and primary mouse adipocytes. Long-term treatment of 3T3-L1 adipocytes with insulin induced up-regulation of PDE3B and PDE4D in a phosphatidylinositol 3-kinase-dependent manner whereas long-term treatment with β-adrenergic agonists induced down-regulation of PDE3B and up-regulation of PDE4D. Thus, PDE3B and PDE4D can be added to the list of genes regulated by insulin and cAMP-increasing hormones. Altered expression of PDE3B and PDE4D in response to long-term treatment with insulin and catecholamines may contribute to altered regulation of metabolism in diabetes.
