Introduction: Osteocalcin (OC) is a marker of bone formation but also seems to play a hormonal role in the regulation of glucose and energy metabolism. Recently, an association of BMI with a haplotype composed of three single nucleotide polymorphisms (SNPs) in the gene for OC, located on chromosome 1q22, was observed in ethnically homogeneous European pedigrees.Aim: The aim of the study was to test the association of these three polymorphisms in the gene...

Preclinical and epidemiologic data suggest that vitamin D deficiency may play a role in the pathogenesis and progression of prostate cancer. Based on recently reported genetic determinants of vitamin D insufficiency we investigated a functional T>G single nucleotide polymorphism (SNP) in the group-specific component (GC) gene for its association with 25-hydroxy (25-OH) vitamin D and 1.25 dihydroxy (1.25-OH) vitamin D levels and further to test a possible association with m...

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...

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...

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...
