A Downstream Intergenic Cluster of Regulatory Enhancers Contributes to the Induction of CYP24A1 Expression by 1α,25-Dihydroxyvitamin D3
18 Mar 2010
Abstract excerpt
CYP24A1 expression is up-regulated by 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) via a vitamin D receptor (VDR)/retinoid X receptor (RXR) heterodimer that binds to two vitamin D response elements (VDREs) located near the proximal promoter. Interestingly, although 1,25(OH)(2)D(3) induced VDR/RXR binding to the VDRE-containing proximal promoter, the VDR/RXR heterodimer also localized to a cluster of at least four...
