The vitamin D hormone, 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)],
binds with high affinity to the nuclear vitamin D receptor (VDR),
which recruits its retinoid X receptor (RXR) heterodimeric partner to
recognize vitamin D responsive elements (VDREs) in target genes……
Moreover, the turmeric-derived polyphenol, curcumin, activates
transcription of a VDRE reporter construct in human colon cancer
cells. Activation of VDR by PUFAs and curcumin may elicit unique,
1,25(OH)(2)D(3)-independent signaling pathways to orchestrate the
bioeffects of these lipids in intestine, bone, skin/hair follicle, and
other VDR-containing tissues.
