Xenopus laevis: a model system for the study of embryonic retinoid metabolism. II. Embryonic metabolism of all-trans-3,4-didehydroretinol to all-trans-3,4-didehydroretinoic acid.

Abstract excerpt

This study demonstrates early embryonic metabolism of exogenous all-trans-3,4-didehydroretinol (vitamin A2) to all-trans-3,4-didehydroretinal and to all-trans-3,4-didehydroretinoic acid in Xenopus embryos during neurulation. The latter metabolite was recently shown to bind with high affinity and to activate various retinoic acid receptors. Embryos treated with all-trans-3,4-didehydroretinol during early or late...
