Immunocytochemical studies were carried out to examine the subcellular localization of plasma retinol-binding protein (RBP) in rat liver. The studies used normal, retinol-deficient, and retinol-repleted retinol-deficient rats with or without colchicine pretreatment. Affinity-purified monomeric Fab' fragments from the IgG fraction of rabbit anti-rat RBP were(More)
Studies were conducted to explore the tissue- and cell-specific regulation of cellular retinoic acid-binding protein (CRABP) expression in the rat. Two studies were carried out. The first explored the regulation of CRABP mRNA levels in selected rat tissues by dietary retinoid status, and the relationship between CRABP mRNA and protein levels in different(More)
The development of high-performance liquid chromatography (HPLC) in the late seventies, enabled us to measure various retinoids in the serum and tissue samples and has contributed to exciting new discoveries of retinoid field. Mainly, serum, retinoids has been measured by reversed phase HPLC with isocratic or gradient mobile eluent. In this paper, several(More)
A study was conducted to determine the levels of cellular retinol-binding protein (CRBP) mRNA and protein in various tissues of the rat, to explore relationship between CRBP mRNA and protein levels in different tissues, and to examine the effects of changes in retinol nutritional status on the tissue distribution and levels of CRBP mRNA. Previous studies(More)
