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

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
Sammanfattning : Background: Topical vitamin D analogues constitute an established treatment for psoriasis but the role of vitamin D in the pathogenesis of the disease remains controversial. The in loco production and immunomodulatory effects of vitamin D need to be elucidated. LÄS MER
