Rat fetuin: distribution of protein and mRNA in embryonic and neonatal rat tissues
1998
Fetuin is a serum protein widely distributed in the animal kingdom and found in all mammalian species so far investigated. It is mainly a fetal protein, in the sense that the highest concentrations are found in serum and body fluids of embryos and fetuses. In order to elucidate possible biological functions of fetuin, we have studied its synthesis and distribution during the prenatal development of the rat with immunohistochemistry and in situ hybridization. We have isolated fetuin from rat serum and produced an antibody against this protein. In situ hybridization was performed using a 375-nucleotides-long digoxigenin-labeled riboprobe. Fetuin was unevenly distributed in all organ systems d…
Fetun-A and end stage renal disease: correlations with haemodialytic single session and genotype
2011
Several studies showed that Fetuin-a is an extracellular calcium-regulatory protein acting as a potent inhibitor of calcium-phosphate precipitation, involved also in bone metabolism because of its high affinity for hydroxyapatite. The aim of this study is to evaluate the serum Fetuin-A levels in patients with chronic renal failure before and after a single session of dialysis and to investigate the correlation between protein serum concentrations and T256S genotype. Our results show that serum Fetuin- A levels decrease 4 hours after haemodialysis treatment and a significant correlation between 256SS homozygote and serum protein levels. Ectopic calcification and particularly intravascular ca…
Low serum Fetuin A levels and cardiovascular events in End-Stage Renal Disease (ESRD) patients.
2008
The atherosclerotic Cardiovascular Disease (CVD) is frequently observed in End-Stage Renal Disease (ESRD) patients; according to the hypothesis of non-traditional risk factors for CVD, accelerated atherogenesis in these patients could be linked to both vascular calcification and inflammation. 2-Heremans-Schmid Glycoprotein (AHSG) also known as Fetuin-A, is considered a negative marker of inflammation and represents one of the in vivo circulating calcification modulators; these molecules are proteins working as endogenous inhibitors of Ca×PO4 precipitation and are probably involved in the pathogenesis vascular calcification. Aim of this study is to evaluate the differences in serum Fetuin-A …
Fetuin-A in elderly: effect of genotype on serum levels
2011
Fetuin-A is a circulating inhibitor of ectopic calcification in vivo; it is decreased in patients with chronic kidney disease and correlates with glomerular filtration rate in patients with coronary artery disease. However, serum levels of Fetuin-A has not been described in elderly. Aim of the study was to evaluate Fetuin-A serum levels together with AHSG T256S genotype in a population of healthy elderly. Serum fetuin-A levels were determined by ELISA. T256S polymorphism of AHSG gene was determined by PCR-RFLP. Serum Fetuin-A was 0,38 ± 0,13 g/l in the group composed by 206 healthy centenarians. Moreover, subjects with at least one S allele had lower Fetuin-A levels (P<001). Interestingly, …
