Common_Name4-oxo-Retinoic acid
Description4-oxo-Retinoic acid is a biologically active geometric isomer of retinoic acid (RA). 4-oxo-retinoic acid is generated from its precursor canthaxanthin and enhances gap junctional communication in cells. Metabolic transformation of all-trans RA to 4-hydroxylated RA appears to be primarily catalyzed by the cytochrome P 450 (CYP) 26AI in human skin cells. Cellular levels of all-trans RA are meticulously regulated utilizing an array of systems to balance uptake, biosynthesis, catabolism, and efflux transport. RA is a critical regulator of gene expression during embryonic development and in the maintenance of adult epithelial tissues. (PMID: 8794203, 7893159, 17330217, 16778795, 17460545)
