The anti-proliferative effect of vitamin D3 analogues is not mediated by inhibition of the AP-1 pathway, but may be related to promoter selectivity.
Recent studies have suggested that the active metabolite of vitamin D3, 1,25-dihydroxyvitamin D3, can inhibit the growth and/or induce the differentiation of a variety of cell types and that these characteristics might be useful in the treatment of some cancers.
Antisense mRNA expression among clones was associated with: (a) reduced or abolished sensitivity to the effects of 1,25(OH)2 D3 on growth; (b) decreased numbers of VDRs per cell, as measured by radiolabelled-ligand binding; and (c) a lack of induction of the VDR-regulated enzyme 24-hydroxylase in response to 1,25(OH)2 D3.
Researchers noted vitamin D deficiency is widespread and said their findings suggest boosting daily intake of vitamin D3 to 1,000 IU would substantially cut the risk of cancers of the colon, breast, ovaries and prostate.
This is likely the reason researchers recommend the D3 form of vitamin D. In most cases, brief periods of unprotected (without sunscreen) sun exposure to face and arms can meet the body's vitamin D needs.
The catch is, the vitamin D may be either D2 or D3, and 400 IU of D2 is far less potent than the same amount of D3.
