    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 : Biological processes take place through interactions between macromolecules, such as nucleic acids and proteins. It is, therefore, fundamental to understand the functions of proteins and how they form complexes in order to carry out their role. LÄS MER

  4. 3. Vitamin D metabolism in osteoblast-like cells : effects of drugs on inactivation by CYP24A1

    Författare :Ahmad Zayny; Maria Norlin; Kjell Wikvall; Håkan Melhus; Inger Johansson; Fredrik Jerneren; Uppsala universitet; []

    Sammanfattning : Vitamin D is essential for bone function, and deficiency in active vitamin D hormone can lead to bone disorders. Long-term treatment with glucocorticoids and antiretroviral drugs used to treat HIV infection, results in osteoporosis and increased risk of fractures. Much remains unclear regarding the effects of these compounds in bone cells. LÄS MER

  5. 4. Expression and regulation of steroid metabolizing enzymes in cells of the nervous and skeletal systems : Special focus on vitamin D metabolism

    Författare :Mokhtar Almokhtar; Maria Norlin; Kjell Wikvall; Gösta Eggertsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Little is known about the mechanisms of vitamin D actions in the brain and bone. In this study, the metabolism of vitamin D and its regulation in various cell cultures of the nervous and skeletal systems were examined. LÄS MER
