Retinoid-binding proteins: mediators of retinoid action.
Active vitamin A metabolites, known as retinoids, are essential for multiple physiological processes, ranging from vision to embryonic development. These small hydrophobic compounds associate in vivo with soluble proteins that are present in a variety of cells and in particular extracellular compartments, and which bind different types of retinoids with high selectivity and affinity. Traditiona...
متن کاملRetinoid receptors and binding proteins.
Retinoids, in particular all-trans retinoic acid (T-RA), are essential for normal development and homeostasis of vertebrates. Although many effects of retinoids, particularly with regard to teratogenicity, have been described in the literature, the mechanisms by which these simple signalling molecules work has only recently begun to be elucidated. We now recognize at least two classes of retino...
متن کاملRetinoid-binding proteins in cone-dominant retinas.
We identified and localized interphotoreceptor (or interstitial) retinoid-binding protein (IRBP) and cellular retinaldehyde-binding protein (CRALBP) in the cone-dominant retinas of diurnal squirrels. Western blots were prepared from sodium dodecyl sulfate polyacrylamide gels (SDS-PAGE) from whole retina, and from retina proximal and distal to the photoreceptor nuclei. Blots were incubated with ...
متن کاملRegulation of adipocyte gene expression by retinoic acid and hormones: effects on the gene encoding cellular retinol-binding protein.
Our laboratory has reported that adipose tissue and adipocytes are importantly involved in retinoid storage and metabolism. To gain further insight, we examined factors that may regulate CRBP mRNA levels in primary cultures of rat epididymal and murine BFC-1 beta adipocytes. Northern blot analysis revealed that retinoic acid is a potent inducer of CRBP mRNA, causing a 7.5-fold rise in mRNA leve...
متن کاملDistribution of endogenous retinoids, retinoid binding proteins (RBP, CRABPI) and nuclear retinoid X receptor beta (RXRbeta) in the porcine embryo.
Retinoids are important signalling molecules in the development of limbs and in the determination of the anterior-posterior orientation of the embryo. The present study examined the content and distribution of retinoic acid, retinol and retinyl esters in porcine embryos during early gestation (gestation days 22-30) macroscopically and microscopically by its autofluorescence and by HPLC. Macrosc...
