Defects in 24-hydroxylation caused by vitamin D-hydroxylase (CYP24A1) loss-of-function mutations lead to decreased degradation of 1,25(OH)2D and the syndrome of idiopathic infantile hypercalcemia. Affected individuals show increased sensitivity to vitamin D and may develop severe hypercalcemia and hypercalciuria, even with small doses of vitamin D.Presenting: The objective of the study was to investigate the gene expression profile in...

Calcification in the vasculature is one of the leading causes of cardiovascular diseases and mortality outcomes. Therefore, the aim of our study was to investigate changes in the gene expression of calcification regulators (CR) in arterial vessels during different stages of atherosclerosis and to document potential corresponding changes in the bone. OPG, RANKL, OPN, MGP, BSP-II and RUNX2 were candidate genes for our study in bone, aorta and arteria ilica externa tissue samples...

Introduction: Calcification of vessels, especially media calcification, in combination with bone demineralization and disturbed bone metabolism is abundant in patients suffering from end stage renal disease (ESRD). In this project, we compare biomarkers of calcification with a focus on microRNAs from ESRD patients listed for renal transplantation (RTX) and healthy controls.Methods: Samples are collected from kidney transplant patients. At the same time t...
