Biochem/physiol Actions

Vitamin D acts through a receptor that is a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects on breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis.

H F DeLuca et al.
Annual review of biochemistry, 52, 411-439 (1983-01-01)
The field of vitamin D metabolism and mechanism of action has continued to be very active. Autoradiography has shown specific nuclear localization of 1,25-(OH)2D3 in target organs prior to initiation of mechanism of action. Specific nuclear localization has also been
Ian R Reid et al.
Lancet (London, England), 383(9912), 146-155 (2013-10-15)
Findings from recent meta-analyses of vitamin D supplementation without co-administration of calcium have not shown fracture prevention, possibly because of insufficient power or inappropriate doses, or because the intervention was not targeted to deficient populations. Despite these data, almost half
Robert P Heaney et al.
The Journal of nutrition, 143(5), 571-575 (2013-03-22)
The magnitude of vitamin D inputs in individuals not taking supplements is unknown; however, there is a great deal of information on quantitative response to varying supplement doses. We reanalyzed individual 25-hydroxyvitamin D [25(OH)D] concentration data from 8 studies involving
