Retinol-binding protein 4 : a possible role in cardiovascular complications

Retinol-Binding Protein 4 in Twins

OBJECTIVE Retinol-binding protein (RBP) 4 is an adipokine of which plasma levels are elevated in obesity and type 2 diabetes. The aims of the study were to identify determinants of plasma RBP4 and RBP4 mRNA expression in subcutaneous adipose tissue (SAT) and skeletal muscle and to investigate the association between RBP4 and in vivo measures of glucose metabolism. RESEARCH DESIGN AND METHODS ...

Retinol-binding protein 4 in human obesity.

Studies in mice suggest that adipocytes serve as glucose sensors and regulate systemic glucose metabolism through release of serum retinol-binding protein 4 (RBP4). This model has not been validated in humans. RBP4 was highly expressed in isolated mature human adipocytes and secreted by differentiating human adipocytes. In contrast to the animal data, RBP4 mRNA was downregulated in subcutaneous...

Serum Retinol-Binding Protein 4 as a Marker for Cardiovascular Disease in Women

BACKGROUND Elevated serum level of retinol-binding protein 4 (RBP4) has been associated with obesity-related co-morbidities including insulin resistance, dyslipidemia and hypertension. OBJECTIVES The present study examined the relationship between serum level of RBP4 and various risk factors related to cardiovascular disease (CVD) in men and women. METHODS 284 subjects (139 males, 145 femal...

Circulating Retinol-Binding Protein 4 and Subclinical Cardiovascular Disease in the Elderly

OBJECTIVE We evaluated associations of serum retinol-binding protein 4 (RBP4) with subclinical cardiovascular disease (CVD). RESEARCH DESIGN AND METHODS Subclinical CVD was measured with echocardiography, carotid artery ultrasound, brachial artery ultrasound, and invasive forearm endothelial vasoreactivity in 1,008 70-year-old participants (50% women) of the Prospective Investigation of the V...
