In hemodialysis (HD) patients, serum prealbumin (TBPA) is correlated to nutritional status and outcome despite usually elevated serum levels. The purpose of this work was to study the role of TBPA-retinol-binding-protein (RBP)-retinol complex changes in the elevation of serum TBPA in HD patients. Serum TBPA, RBP, and retinol were measured in 30 otherwise healthy HD patients (15 men, 15 women) a...
We recently demonstrated a rapid up-regulation of serum retinol-retinol binding protein-transthyretin concentration in rats with short-term acute renal failure. We examine the effect of retinoic acid and apo-retinol binding protein (apo-RBP) on the up-regulation of serum retinol in renal failure. Injection of retinoic acid (10 micrograms) into rats with acute renal failure or sham-operated rats...
Vitamin A (retinol) is absorbed in the small intestine, stored in liver, and secreted into circulation bound to serum retinol-binding protein (RBP4). Circulating retinol may be taken up by extrahepatic tissues or recycled back to liver multiple times before it is finally metabolized or degraded. Liver exhibits high affinity binding sites for RBP4, but specific receptors have not been identified...
Vitamin A circulates in human plasma as retinol bound to a specific transport protein. This protein differs from the known low and high density plasma lipoproteins and has a hydrated density greater than 1.21. In order to study this protein, volunteers were injected intravenously with retinol-15-(14)C. Plasma was collected 1-3 days later, and the purification of retinol-binding protein (RBP) wa...
