作者： Li-Na Wei Department of pharmacology University of Minnesota Medical School

Retinoic acid(RA), the active metabolite of vitamin A(the retinoids), elicits a wide spectrum of biological activities critical to the development and health of most of the organ systems including the nervous systems(Corcoran et al., 2002). The effects of RA are mediated by two very distinct pathways; the first is manifested in the nucleus by binding to a large family of nuclear RA receptors(RARs) to regulate proper expression of RAtargeted genes,
