VIT32, a vasopressin-induced transcript, inhibits Na+ transport when coexpressed with the epithelial sodium channel in Xenopus laevis oocytes ( EMBO J 21: 5109–5117, 2002). To understand the mechanism of VIT32 gene regulation, we examined the effect of DDAVP and cAMP stimulation on VIT32 expression in M-1 mouse collecting duct cells and in H441 human airway epithelial cells. Elevation of cAMP with forskolin and IBMX increased VIT32 gene expression with a peak effect at 2 h. The increase in gene expression was abolished by H89 and by actinomycin D, suggesting that cAMP stimulates VIT32 mRNA expression by a PKA-mediated increase in gene transcription. An ∼1.5-kb fragment of the 5′-flanking region of VIT32 was cloned and was able to confer cAMP-stimulated reporter gene activity when transfected into M-1 and H441 cells. By deletion analysis and site-directed mutagenesis, a cAMP response element (CRE) was identified within the proximal promoter region that was sufficient to account for the increase in VIT32 gene expression seen with DDAVP and elevation of cAMP. Furthermore, DDAVP-stimulated VIT32 promoter-reporter activity was inhibited by H89 and by a dominant negative CREB construct. Finally, we were able to identify CREB as a nuclear protein that bound to the VIT32 CRE in gel mobility shift assays. In summary, DDAVP stimulates transcription of VIT32 via a CRE within the proximal promoter region of the VIT32 gene.
