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 vessel wall: impact of vitamin K dependent proteins

Pathophysiological calcification in the vasculature favours cardio- and cerebrovascular diseases. In patients with chronic kidney disease vitamin K metabolites are associated with decreased vascular calcification.We investigated the expression of vitamin K dependent proteins (VKDPs) in vessels and bone to identify differences in expression pattern during atherosclerosis (AS) stages and compare the two tissue profiles.Gene expressio...

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...

Gene expression in vascular calcification: are there differences between atherosclerotic changes and media sclerosis?

Background: Pathophysiological calcification in the vasculature is a risk factor for cardiovascular disease (CVD). CVD are among the most common causes of death in patients with chronic kidney disease and crucial for kidney transplantation (RTX) outcomes.Aim: The aim of this study is to identify differences in the pattern and the onset of expression of regulators of calcification (RC) in atherosclerosis (AS) and media sclerosis (MS).<p class="abstext...
