  1. 1. Regulation of Vitamin D 25-hydroxylases Effects of Vitamin D Metabolites and Pharmaceutical Compounds on the Bioactivation of Vitamin D

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maria Ellfolk; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP2D25; vitamin D 25-hydroxylase; transcriptional regulation; vitamin D; CYP2R1; CYP2J2; CYP27A1; phenobarbital; efavirenz; fibroblast; LNCaP; PHARMACY Pharmaceutical biochemistry; FARMACI Farmaceutisk biokemi;

    Abstract : 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. READ MORE

  2. 2. Vitamin D Hydroxylating Enzymes and Analogues in Parathyroid Tumors and Breast Cancer

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ulrika Segersten; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; hyperparathyroidism; breast cancer; vitamin D; CYP27B1; CYP24A1; vitamin D analogues; ketoconazole; vitamin D receptor; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; Surgery; kirurgi;

    Abstract : 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. READ MORE

  3. 3. Boning up on Vitamin D Observational Studies on Bone and Health

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Greta Snellman; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vitamin D; fracture; BMD; assays; genes; mortality; cohort studies; Orthopaedics; Ortopedi;

    Abstract : 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. READ MORE
