1. The Role of Fibroblast Growth Factor 23 in Phosphate Homeostasis
Sammanfattning : 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.

3. Expression and regulation of steroid metabolizing enzymes in cells of the nervous and skeletal systems : Special focus on vitamin D metabolism
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
4. Vitamin D and its role in obesity and other associated conditions
Sammanfattning : 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.

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