1. Regulation of Vitamin D 25-hydroxylases : Effects of Vitamin D Metabolites and Pharmaceutical Compounds on the Bioactivation of Vitamin D
Sammanfattning : A 700bp portion of the promoter of CYP2D25, the porcine microsomal vitamin D 25-hydroxylase was isolated and sequenced. The computer analysis of the sequence revealed the existence of a putative VDRE at 220 bp upstream of the transcription start site. LÄS MER
2. Aspects of Vitamin D : Prevalence of deficiency and impact on musculoskeletal parameters
Sammanfattning : Vitamin D is central in calcium turnover, and adequate levels are important for skeletal health. It is not clear how large contributions from food and sunlight are in Swedish primary care patients, considering the low radiation of UVB in Sweden and fortification of some foods, and whether differences exist between patients of immigrant and Swedish origin.

3. Boning up on Vitamin D : Observational Studies on Bone and Health
Sammanfattning : The primary function of vitamin D in humans is to maintain sufficient circulating calcium concentrations. Low vitamin D levels could result in excessive calcium resorption from bone. Vitamin deficiency may therefore decrease bone mineral density (BMD), resulting in an increased risk of fracture. LÄS MER
4. Vitamin D Hydroxylating Enzymes and Analogues in Parathyroid Tumors and Breast Cancer
Sammanfattning : In hyperparathyroidism (HPT) raised serum concentrations of ionized calcium is caused by increased secretion of parathyroid hormone (PTH) by parathyroid tumors. Active vitamin D, 1α,25-dihydroxyvitamin D3, is known to suppress PTH secretion and to reduce proliferation of parathyroid tumor cells. LÄS MER
