The effects of dibutyryl cAMP (Bt2cAMP) and phorbol esters such as 12-O-tetradecanoylphorbol-13-acetate (TPA) and phorbol-12,13-didecanoate (PDD) on VIP PHM-27 gene expression in human neuroblastoma cells in culture were investigated. Bt2cAMP and phorbol esters increased the VIP PHM-27 mRNA level by about 9- and 4-fold, respectively. In the presence of both Bt2cAMP and phorbol esters, the VIP PHM-27 mRNA level increased by about 36-fold. The intracellular cAMP level was essentially unaffected by phorbol esters. The VIP PHM-27 gene dosage was unchanged by Bt2cAMP and phorbol esters. The results suggest that cAMP and phorbol esters synergistically induce the VIP PHM-27 gene expression through independent pathways.
