Differential expression and ligand regulation of the retinoic acid receptor alpha and beta genes.


Retinoic acid (RA) is a vitamin A derivative that exhibits major effects on biological processes such as cell differentiation and embryo pattern formation. Two human retinoic acid receptors (RAR alpha and beta) have been recently characterized. These receptors are encoded by two genes and their affinities for RA differ, suggesting that these two nuclear… (More)
