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

In our previous study, higher serum 25-hydroxyvitamin D [25(OH)D] concentrations and the vitamin D receptor (VDR) FokI CC genotype were associated with milder Parkinson disease (PD). We evaluated whether vitamin D3 supplementation inhibits the progression of PD on the basis

Vitamin D supplementation in infancy is required to support healthy bone mineral accretion. A supplement of 400 IU of vitamin D per day is thought to support plasma 25-hydroxyvitamin D (25[OH]D) concentrations between 40 and 50 nmol/L; some advocate 75

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
