    Author : Tobias Erik Martin Larsson; Kenneth Jonsson; Östen Ljunggren; Suzanne Jan De Beur; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Fibroblast Growth Factor 23; FGF-23; phosphate homeostasis; vitamin D metabolism; sodium phosphate cotransporters; autosomal dominant hypophosphatemic rickets; ADHR; X-linked hypophosphatemic rickets; XLH; oncogenic osteomalacia; OOM; PHEX; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : The regulation of serum phosphate (Pi) concentrations is a complex process and our current models are far from complete. Due to major advancements in biotechnology and the development of more powerful research tools, recent advances in the field of genetics has led to the identification of several candidates for the long sought-after phosphatonin(s), or Pi regulating hormones.

    Abstract : Vitamin D has received much attention in recent years due to the re-emergence of vitamin D deficiency as a global health issue along with increasing evidence indicating that 1,25-dihydroxivitamin D, the hormonally active form of vita-min D, not only acts in calcium and bone metabolism but also generates ex-traskeletal biological responses.In this thesis, the role of vitamin D in obesity and other associated condi-tions has been studied.
