Abstract

All-trans 3,4-didehydroretinoic acid (at-ddRA) has been identified as a biologically important retinoid in avian, but not mammalian, embryonic development. In this report, we show that at-ddRA, like all-trans retinoic acid (atRA), supports the survival and differentiation of sympathetic neurons of the embryonic chick. Furthermore, the expression of the retinoid- responsive gene RARβ2 is increased in neurons exposed to either at-ddRA or atRA. The mechanism whereby at-ddRA exerts its effects in chick neurons may involve binding to and activation of nuclear retinoid receptors. For this reason, the binding of recombinant chick RARβ2 to at-ddRA and to receptor- specific DNA response elements was examined and compared with the binding characteristics of recombinant murine RARβ2. The chick RARβ2, like the mammalian RAR, binds to [3H]atRA with high affinity (K(d)=0.7-2 nM). Furthermore, both chick and murine RARβ2 bind equally well to at-ddRA, atRA, and 9-cis RA, hut neither receptor shows appreciable binding to 13-cis RA. The chick RARβ2 recognizes previously described retinoic acid response elements of mammalian gene promoters and, like mammalian RARβ2, shows enhanced binding in the presence of RXR. This study provides evidence that at-ddRA, like atRA, supports neuronal development in the chick by its interaction with nuclear retinoid receptors.
