Retinol metabolism in rats with low vitamin A status: a compartmental model
A compartmental model was developed to describe the metabolism of vitamin A in rats with low vitamin A status maintained by a low dietary intake of vitamin A (approximately 2 micrograms retinol equivalents/day).

Transcriptome shifts triggered by vitamin A and SCD genotype interaction in Duroc pigs
Background The composition of intramuscular fat depends on genetic and environmental factors, including the diet. In pigs, we identified a haplotype of three SNP mutations in the stearoyl-coA desaturase (SCD) gene promoter associated with higher content ...

Isolation and Properties of a Human Retinol-transporting Protein
A human retinol-transporting protein has been isolated from the urine of patients with tubular proteinuria. The protein separated into four fractions in the last two purification steps (sulfoethyl Sephadex chromatography and DEAE-Sephadex chromatography). The yield of purified retinol-binding protein (RBP) was 33 to 41% of the amount in concentrates of

Exome analysis identified a novel mutation in the RBP4 gene in a consanguineous pedigree with retinal dystrophy and developmental abnormalities. [PDF]
Retinitis Pigmentosa (RP) is a common form of retinal degeneration characterized by photoreceptor degeneration and retinal pigment epithelium (RPE) atrophy causing loss of visual field and acuities.

Real-time Analyses of Retinol Transport by the Membrane Receptor of Plasma Retinol Binding Protein
Vitamin A is essential for vision and the growth/differentiation of almost all human organs. Plasma retinol binding protein (RBP) is the principle and specific carrier of vitamin A in the blood. Here we describe an optimized technique to produce and purify holo-RBP and two real-time monitoring techniques to study the transport of vitamin A by the high ...
