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.
