Interphotoreceptor retinol-binding protein (IRBP) is a large retinol-carrying glycoprotein, located only in the interphotoreceptor (or subretinal) space of vertebrate eyes. It has recently been purified to apparent homogeneity. The present report presents its sedimentation, spectroscopic, and binding properties. The molecular weight of bovine IRBP, determined by sedimentation equilibrium, is 13...
Aim—To investigate factors that influence urinary tissue factor (uTF) measurements: glomerular permeability and filtration, tubular function, haematuria, and urine bacterial growth. Methods—uTF, protein creatinine index, glomerular filtration rate, retinol binding protein, N-acetyl-â-D-glucosaminidase (NAG) and urinary haemoglobin (uHb) were measured in patients with hypertension, diabetes mell...
Vitamin A (retinol) is required to maintain immunity and epithelial turnover and is a key micronutrient needed for combating infection. Vitamin A actions on the immune system are diverse and cannot be accounted for by a single effect or mechanism. The actions of retinol in maintaining gut integrity in humans and immunoglobulin levels in mice was investigated. For 30 children, performance on the...
Tissue uptake and distribution of retinol from circulatory vitamin A transport complex was studied in order to determine the origin of the increased serum retinol in rats with short-term acute renal failure. In rats with acute renal failure, serum retinol increased 37-70% within 2 h after surgery. After an injection of donor plasma containing 1.8 muCi of [3H]retinol in retinol transport complex...
Retinol binding protein 4 is associated with adiposity-related co-morbidity risk factors in children
Serum vitamin A homeostasis was studied in rats with nonfiltering kidneys prepared by ligation of renal arteries. Within 1-2 h of acute renal failure, the serum retinol level increased by 11-73% and was maintained for at least 4 h. More than 90% of the increase in serum retinol was associated with retinol in the retinol binding protein-transthyretin (RBP-TTR) complex. The activities of acyl-CoA...
