). Cellular-binding proteins for vitamin A (retinol) and its active derivative, retinoic acid (RA), CRBP, and CRABP, had been discovered by that time and it had been proposed that CRABP might be involved in mediating the effects of RA on gene expression

Introduction The history of retinoic acid (RA) signaling began with the discovery that its precursor vitamin A (also called retinol) is essential for embryonic growth and development as shown by vitamin A deficiency studies ( Wilson et al

aromatase expression in breast adipose fibroblasts (BAFs). In this study, we show that ligands of the retinoic acid receptors (RARs), all- trans -RA (at-RA) and 9- cis -RA (9 cis -RA), induce aromatase activity in human BAFs via a retinoic acid response
