ABSTRACT
Forskolin and cAMP have been shown to have paradoxical effects in the regulation of expression levels of mRNA of cytochrome P450 3A (CYP3A) family members. We demonstrate in this study that forskolin upregulated the promoter for CYP3A4 independent of its ability to increase cAMP levels. This activity was explained showing forskolin directly activated the pregnane-X-receptor, a known regulator of CYP3A genes.
