Uptake of retinol and retinoic acid from serum retinol-binding protein by retinal pigment epithelial cells.
Isolated pigment epithelial cells from bovine eyes were shown to be capable of taking up retinol and retinoic acid. The uptake was dependent on the ligands being presented to the cells as complexes with serum retinol-binding protein. Neither free retinol nor retinol or retinoic acid presented as serum albumin complexes were taken up by the pigment epithelial cells. The transport of retinal and ...
متن کاملBiochemical indicators of vitamin A deficiency: serum retinol and serum retinol binding protein.
Two biochemical indicators are currently recommended for determining whether vitamin A deficiency (VAD) is a public health problem: serum retinol and serum retinol-binding protein (RBP). After consideration of 40 data sets and the original rationale for previously proposed cut-offs, a cut-off for serum retinol concentration was proposed at <0.70 micro mol/L (20 micro g/dL) in > or =15% of the s...
متن کاملA radioimmunoassay for retinol-binding protein in serum and urine.
In this radioimmunoassay for human retinol-binding protein (RBP), sample (serum, diluted as much as 3600-fold; or urine, diluted or undiluted) or calibrant (purified RBP in phosphate buffer containing bovine serum albumin) is incubated with 125I-labeled RBP and rabbit anti-human RBP antiserum for 24 h before separation with second antibody/polyethylene glycol. The assay's sensitivity is 5 micro...
متن کاملImmunonephelometric determination of retinol-binding protein in serum and urine.
An immunonephelometric method developed for measurement of retinol-binding protein (RBP) in serum and urine can detect it in concentrations of about 30 micrograms/L, which is in the lower limit of its normal concentration in urine (range 0-0.56 mg/L; mean +/- SD 0.19 +/- 0.15; n = 44). Urinary RBP was increased (range 0.93-29.5 mg/L) in all of 25 urine specimens from 13 subjects being treated w...
متن کاملInteraction of the retinol/cellular retinol-binding protein complex with isolated nuclei and nuclear components
Retinol (vitamin A alcohol) is involved in the proper differentiation of epithelia. The mechanism of this involvement is unknown. We have previously reported that purified cellular retinol-binding (CRBP) will mediate specific binding of retinol to nuclei isolated from rat liver. We now report that pure CRBP delivers retinol to the specific nuclear binding sites without itself remaining bound. T...
