Characterization of two post-translationally processed forms of human serum retinol-binding protein: altered ratios in chronic renal failure.

Journal of Lipid Research, 1995
Retinol-binding protein (RBP) is the specific blood carrier for the transport of retinol (vitamin A) to target tissues. As the kidney is involved in RBP metabolism, the analysis of RBP species in the serum of patients with chronic renal failure (CRF) was

Effects of acute inflammation on plasma retinol, retinol-binding protein, and its mRNA in the liver and kidneys of vitamin A-sufficient rats

Journal of Lipid Research, 1996
The acute inflammatory response to tissue injury and infection is associated with low concentrations of plasma retinol and its specific transport proteins, retinol-binding protein (RBP) and transthyretin (TTR).

Vitamin A equivalency of ß-carotene in healthy adults: limitation of the extrinsic dual-isotope dilution technique to measure matrix effect [PDF]

, 2009
Data on the vitamin A equivalency of ß-carotene in food are inconsistent. We quantified the vitamin A equivalency (¿g) of ß-carotene in two diets using the dual-isotope dilution technique and the oral¿faecal balance technique.

Retinol metabolism in rats with low vitamin A status: a compartmental model

Journal of Lipid Research, 1990
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

BMC Genomics, 2022
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 ...

Molecular basis for the interaction of cellular retinol binding protein 2 (CRBP2) with nonretinoid ligands

Journal of Lipid Research, 2021
Present in the small intestine, cellular retinol binding protein 2 (CRBP2) plays an important role in the uptake, transport, and metabolism of dietary retinoids.

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Isolation and Properties of a Human Retinol-transporting Protein

Journal of Biological Chemistry, 1971
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

Vitamin A metabolism is changed in donors after living-kidney transplantation: an observational study

Lipids in Health and Disease, 2011
Background The kidneys are essential for the metabolism of vitamin A (retinol) and its transport proteins retinol-binding protein 4 (RBP4) and transthyretin.
