purpose. To determine whether the visual cycle is affected in mice without a functional gene for cellular retinol-binding protein type I (CRBPI −/− mice).. methods. Visual-cycle retinoids and rhodopsin levels were analyzed in eyes of dark adapted (DA) CRBPI −/− and wild-type (wt) mice before and during recovery from a flash. The rate of dark adaptation was analyzed using electroretinography (ERG).. results. all-trans-Retinyl esters were reduced to approximately 33% of wt levels in DA CRBPI −/− mice. Recovery from a flash in wt mice produced transient accumulations of all-trans-retinal and all-trans-retinyl ester, as the pulse of retinoid produced by the flash traversed the visual cycle. In CRBPI −/− mice, all-trans-retinal accumulated transiently, as in wt mice. However, all-trans-retinol also accumulated transiently in the neural retina, and the transient increase in all-trans-retinyl ester of the wt was reduced. Rates of 11-cis-retinal and rhodopsin formation were comparable in ...

BACKGROUND/AIM Cellular retinol binding protein-1 regulates retinol bioavailability and contributes to cell differentiation maintenance, but its role in ovarian carcinogenesis remains uncertain. We investigated CRBP-1 expression in ovarian tumors and CRBP-1 signaling-regulated pathways. MATERIALS AND METHODS We performed immunohistochemistry, methylation-specific PCR, gene copy number analysis in ovarian tumors and proliferation/apoptosis evaluation, gene array, blot and real-time PCR in CRBP-1-transfected A2780 ovarian cancer cells. RESULTS CRBP-1 expression was reduced or absent in G2 and G3 ovarian carcinomas. CRBP-1 silencing in 60% of G2 and 66.7% of G3 carcinomas was due to CRBP-1 promoter methylation. A2780 CRBP-1-transfected cells showed increased retinol-induced apoptosis, retinoid-induced reduced clonogenicity and down-regulation of proliferation and transcription genes, including AKT1, AKT3, EGFR, FOS, JUN, STAT1 and STAT5A. CONCLUSION CRBP-1 loss in G2/G3 ovarian carcinomas and

Introduction. The majority of biochemical transactions performed in organisms are carried out by proteins, the functions of which are dependent upon their three-dimensional structures. The shape assumed by a protein molecule, and its stability, in turn, is determined by numerous environmental factors, such as molecular crowding. Although the environment within cells and biological fluids is highly crowded by macromolecules,1 and because the excluded volume effect is a fundamental characteristic of crowded solutions,2,3 most studies on protein stability and function are performed with dilute protein solutions in the absence of other macromolecules. In order to understand the behaviour of globular proteins in vivo better, it is important to investigate the influence of a crowded environment on their stabilities and functions.. It was recently shown that the thermodynamic stabilities of two monomeric proteins, ( repressor and cellular retinoic acid-binding protein I, measured in vivo are very ...

This gene encodes a specific binding protein for a vitamin A family member and is thought to play an important role in retinoic acid-mediated differentiation and proliferation processes. It is structurally similar to the cellular retinol-binding proteins, but binds only retinoic acid at specific sites within the nucleus, which may contribute to vitamin A-directed differentiation in epithelial tissue.

Native Human RETINOL BINDING PROTEIN protein (code: DS-01-0390). Purified protein from the urine of patients with chronic renal tubular proteinuria - lyophilized.
We report here the gene expression patterns, as revealed by in situ hybridisation, of the retinoic acid receptors alpha, beta and gamma (RAR-alpha, -beta and -gamma), and the cellular binding proteins for retinol and retinoic acid (CRBP, CRABP) in non-neural tissues of mouse embryos during the period of organogenesis. At all stages, RAR-alpha transcripts were almost ubiquitous, whereas the distribution of transcripts of the other four genes was distinctive in all systems. At early stages in the formation of an organ, the expression patterns were different in the epithelium, the adjacent mesenchyme, and in mesenchyme more distant from the epithelium, suggesting a role for RA and RA receptors in epithelial-mesenchymal tissue interactions. In the developing face, limb bud and genital tubercle, where large expanses of mesenchyme are present, differential patterns of expression were established before the onset of overt tissue differentiation, suggesting some significance for pattern formation in ...

Objective(s):Psoriasis is an autoimmune disease that appears on the skin. Although psoriasis is clinically and histologically well characterized, its pathogenesis is unknown in detail. The aims of this study were to evaluate the proteome of psoriatic patients sera and to compare them with those of normal healthy human to find valuable biomarkers. Materials and Methods: In a case-control study, twenty cases of white patients with psoriasis vulgaris, 10 males and 10 females and sixteen healthy controls, 8 males and 8 females were enrolled in the study. The serum protein expression patterns obtained after depletion of albumin were compared by using two dimensional gel electrophoresis (2-DE) coupled to MALDI/TOF-TOF to identify disease associated proteins. Results: Differential expression of nine protein spots representing four unique proteins including alpha-1 antitrypsin, retinol binding protein, keratin 10 and an unknown protein (with pI 6.47 and molecular weight of 19941 Da), between psoriatic and

The coding region was followed by TAG translation terminating codon ...
Enzyme-linked immunosorbent assays (ELISA) have been developed for the measurement of beta 2-microglobulin (B2M), retinol-binding protein (RBP), alpha 1-microglobulin (A1M) and urine protein 1 (UP1) in children. Results from random urine samples in 43 children (31 for B2M) are, when corrected for urine creatinine (geometric mean (range)): B2M 9.8 (6.0-40.7) micrograms/mmol, RBP 8.1 (less than 1-24.5) micrograms/mmol, A1M 0.4 (0.1-2.2) mg/mmol and UP1 17.8 (less than 2-309.4) micrograms/mmol. Fractional excretions (FE) in 23 children (14 for B2M) are (geometric mean (range)): FEB2M 0.04% (0.02-0.10%) and FEUP1 0.10% (0.01-1.21%). Results in overnight urine collections are also presented. Our results extend existing data for normal ranges in adults to include children and provide data on UP1 concentrations.

Liver has enormous capacity to store vitamin A which is stored in the form of retinol palmitate. Under normal condition, a well fed person has enough vitamin A storage to meet his needs for 6-9 months. Free retinol is highly active but toxic and is therefore transported within the blood stream in association with retinol binding protein which is produced by the liver. In case of severe deficiency, decreased production of retinol binding protein prevents the mobilization of liver retinol reserves.. ...
Vitamin A has a large number of biological functions, including roles in vision, reproduction, immunity, tissue regeneration, and neuronal signaling. The existence of a cell surface receptor for the vitamin A carrier retinol binding protein (RBP) was proposed more than 30 years ago. Kawaguchi et al. now report the identification and characterization of the long-sought RBP receptor. The RBP receptor is a multipass-transmembrane domain protein with robust RBP binding and vitamin A uptake activity and is localized to the expected cellular locations for vitamin A uptake.. R.

Polar molecules and large ions dissolved in water cannot diffuse freely across the plasma membrane due to the hydrophobic nature of the fatty acid tails of the phospholipids that make up the lipid bilayer. Only small, non-polar molecules, such as oxygen and carbon dioxide, can diffuse easily across the membrane. Hence, no nonpolar molecules are transported by proteins in the form of transmembrane channels. These channels are gated, meaning that they open and close, and thus deregulate the flow of ions or small polar molecules across membranes, sometimes against the osmotic gradient. Larger molecules are transported by transmembrane carrier proteins, such as permeases, that change their conformation as the molecules are carried across (e.g. glucose or amino acids). Non-polar molecules, such as retinol or lipids, are poorly soluble in water. They are transported through aqueous compartments of cells or through extracellular space by water-soluble carriers (e.g. retinol binding protein). The ...
I think the first key experience was the choice of my research focus during graduate school. I tried many different research experiences as an undergraduate at the University of Miami, trying to find the area of research that most appealed to me. Eventually, I worked with computational chemist Jeffrey Evanseck on obtaining a molecular model of human retinol binding protein. This is when it clicked for me and I realized that this was what I wanted to study in graduate school. With his help, I charted a course for graduate studies in this field and ultimately pursued my Ph.D. at the Scripps Research Institute. While there, I feel fortunate to have joined the group of Charles L. Brooks III, which provided an optimal environment to pursue my degree. My experiences in Dr. Brooks group solidified my love of research and were a significant factor in my choice to pursue an academic career. After receiving my Ph.D., I pursued postdoctoral studies with Dr. Greg Voth at the University of Utah. This was ...

Introduction: Fenofibrate is a peroxisome proliferator-activated receptor (PPAR)-alpha agonist which showed beneficial effects on lipid profile and total cardiovascular risk in patients with type 2 diabetes in the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study. This study aimed to investigate the long-term effect of fenofibrate therapy on three novel biomarkers of cardiovascular risk, namely adipocyte-fatty acid binding protein (A-FABP), fibroblast growth factor 21 (FGF21), and retinol-binding protein 4 (RBP4), which are all downstream targets of PPAR-alpha or PPAR-gamma, in patients with type 2 diabetes.. Methods: A total of 216 patients (108 in the fenofibrate group and 108 in the placebo group) were randomly selected from the FIELD study cohort. A-FABP, FGF21, and RBP4 levels were measured in serum samples at both baseline and the fifth year of the study.. Results: Relative to the placebo group, the changes of serum FGF21 and RBP4 levels were 85% (P,0.001) and 10% ...
