Retinoids binding proteins, cellular

The specific role of vitamin A in tissue differentiation has been an active area of research. The current thinking, developed in 1979, involves initial dehvery of retinol by holo-B >V (retinol-binding protein) to the cell cytosol (66). Retinol is then ultimately oxidized to retinoic acid and binds to a specific cellular retinoid-binding protein and is transported to the nucleus. Retinoic acid is then transferred to a nuclear retinoic acid receptor (RAR), which enhances the expression of a specific region of the genome. Transcription occurs and new proteins appear during the retinoic acid-induced differentiation of cells (56). [Pg.103]

Retinyl esters 102a-c (1 mCirnl ) stored under argon at —60°C in toluene containing 40 /ig of 2-t-butyl-4-methoxyphenol and 4 pL of pyridine are quite stable. After 1 year about 60% decomposition was noted, due to radiolysis in the case of 102c. Retinoic acid 103 under similar conditions is also radiochemically stable, but after 4 months the material has to be repurified. Specific activities of tritium-labelled retinoids in the 10-40 Cimmol range have been found necessary in view of the discovery and use of cellular retinoid binding proteins. ... [Pg.809]
