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

    Author : Ulrika Segersten; Gunnar Westin; Per Hellman; Göran Åkerström; Martin Bäckdahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; hyperparathyroidism; breast cancer; vitamin D; CYP27B1; CYP24A1; vitamin D analogues; ketoconazole; vitamin D receptor; Kirurgi; Surgery; 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

  4. 2. Vitamin D and Breast Cancer. Studies on Incidence and Survival

    Author : Linnea Huss; Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; risk; prognosis; vitamin D; PTH; calcium; SNP; VDR.;

    Abstract : Previous research has suggested beneficial effects of vitamin D on both breast cancer risk and prognosis. The overall aim of this research project was to investigate associations between vitamin D and breast cancer. The population-based prospective cohort, the Malmö Diet and Cancer Study, recruited 17,034 women in the first half of the 1990s. READ MORE

  5. 3. Exploring vitamin D and steroid hormone receptors – from healthy elderly to prostate cancer cells

    Author : Maria Araceli Diaz Cruz; Maria Faresjö; Dennis Larsson Dennis Larsson; Johan Staaf; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vitamin D; steroid hormone receptors; lifestyle; methylation; SNPs; healthy elderly; prostate cancer cells; crosstalk; PDIA3;

    Abstract : The genetic background together with environmental factors and lifestyle are key contributors to the health of an individual. Genetic background is inherited and irreversible unless mutations occur. However, lifestyle habits (i.e. READ MORE

  6. 4. Calcium metabolism and breast cancer risk

    Author : Martin Almquist; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; calcium; breast cancer; vitamin D; body mass index; menopause; parathyroid hormone;

    Abstract : Emerging evidence suggests that calcium and its regulating hormones, i.e. vitamin D and parathyroid hormone (PTH), affect breast cancer risk. READ MORE

  7. 5. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones

    Author : Johan Lundqvist; Kjell Wikvall; Maria Norlin; Magnus Ingelman-Sundberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenal steroidogenesis; CYP7B1; vitamin D; calcitriol; enzymatic regulation; transcriptional regulation; CYP21A2; aromatase; sex hormone; estrogen; androgen; nuclear receptor; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.
