Fetuin-A, a hepatic secretory protein, has recently been implicated in insulin resistance and Type 2 diabetes. It is an endogenous inhibitor of insulin receptor tyrosine kinase. However, regulation of fetuin-A synthesis in relation to insulin resistance is unclear. In the present paper, we report that both non-esterified ('free') fatty acids and fetuin-A coexist at high levels in the serum of d...

Fetuin A/AHSG was first isolated by Pedersen in 1944 from the fetal bovine serum. In adult humans, fetuin A is mainly secreted by the liver and the adipose tissue and it acts as an inhibitor of ectopic calcification. Fetuin A is also related to critical aspects of cardiometabolic health in humans such as insulin sensitivity, glucose tolerance, non-alcoholic fatty liver disease, atherosclerosis,...

The serum protein fetuin-A is a potent systemic inhibitor of soft tissue calcification. Fetuin-A is highly effective in the formation and stabilization of protein-mineral colloids, referred to as calciprotein particles (CPPs). These particles ripen in vitro in a two-step process, indicated by a morphological conversion from spheres to larger prolate ellipsoids. Using a combined light scattering...

In the article by Eraso et al. (1), circulating fetuin-A was lower in subjects with type 2 diabetes and an ankle brachial index (ABI) 0.9 compared with individuals with higher ABI. Furthermore, in an unadjusted model circulating fetuin-A correlated positively with ABI. It was concluded that low circulating fetuin-A may serve as a biomarker of peripheral arterial disease (PAD). This conclusion i...

OBJECTIVE Fetuin-A levels are associated with higher risk of type 2 diabetes, but it is unknown if the association is causal. We investigated common (>5%) genetic variants in the fetuin-A gene (AHSG) fetuin-A levels, fasting glucose, and risk of type 2 diabetes. RESEARCH DESIGN AND METHODS Genetic variation, fetuin-A levels, and fasting glucose were assessed in 2,893 Caucasian and 542 African...

OBJECTIVES The aim of this study was to determine the association of fetuin-A with subclinical cardiovascular disease (CVD) in community-living individuals. BACKGROUND Fetuin-A is a hepatic secretory protein that inhibits arterial calcium deposition in vitro. Lower fetuin-A levels are associated with arterial calcification and death in end-stage renal disease populations. The association of f...

PURPOSE Fetuin-A is a multifunctional hepatic secretory protein that inhibits dystrophic vascular and valvular calcification. Our aim was to evaluate the relationship among fetuin-A levels, heart valve calcification and other biomarkers of inflammation in patients with acute coronary syndrome (ACS). METHODS The associations among serum fetuin-A concentrations, mitral annular (MAC) and aortic ...

AIM Fetuin-A plays a role in insulin resistance and cardiovascular disease. This study aims to determine the relationship between fetuin-A levels and cardiometabolic risk factors, as well as to investigate the effect of serum fetuin-A on insulin resistance indices to determine whether fetuin-A is an additional marker for insulin resistance in prepubertal children. METHODS A total of 99 prepub...

Objective. Fetuin-A has been associated with gestational diabetes mellitus (GDM). We investigated fetuin-A levels during and after pregnancy in women with GDM. Fetuin-A measurements were performed in 10 women with GDM and 10 age and body mass index (BMI) matched healthy pregnant women. All women underwent an oral glucose tolerance test (OGTT) in and 3 months after gestation. Results. Fasting fe...

BACKGROUND Vascular stiffening occurs in normal ageing and is accelerated in chronic kidney disease (CKD). Vascular calcification contributes to this stiffening and to the high incidence of vascular morbidity and mortality in this population. A network of inhibitors work in concert to reduce mineralization risk in extra-osseous tissue. Fetuin-A is an important systemic inhibitor of ectopic calc...
