Application

Retinoic acid (RA) has been used for the differentiation of embryonic stem cells into motor neurons. It has been used for the differentiation of Xenopus ectoderm into pancreas. It has also been used to study epigenetic regulation by RARα (retinoic acid receptor α). It has been used to study RA signaling of prospermatogonia transition into spermatogonia.

Biochem/physiol Actions

all−trans−Retinoic acid (ATRA) is a ligand for both the retinoic acid receptor (RAR) and the retinoid X receptor (RXR). The bound RAR and RXR act as transcription factors that regulate the growth and differentiation of both normal and malignant cells. Cytochromes P450 (CYPs) catalyze the 4-hydroxylation of ATRA. Retinoic acid primes embryonic stem cells to become neurons.
