Application

9-cis-Retinoic acid has been used:
  • as ligand for retinoid X receptor gamma (RXRγ) for inducing oligodendrocyte precursor cells differentiation and remyelination
  • as a medium component to study its effect on UDP-glucuronosyltransferases (UGT) expression in thyroid induced hepatocytes
  • to induce lymphangiogenesis in lymphatic endothelial cell

Biochem/physiol Actions

Ligand for both the retinoic acid receptor (RAR) and the retinoid X receptor (RXR) that act as transcription factors to regulate the growth and differentiation of normal and malignant cells.
9-cis-Retinoic acid (9cRA) is an isomer of all-trans-retinoic acid (ATRA), both of which are lipid molecules synthesized from a common precursor, vitamin A. 9cRA is a potent agonist for retinoid X receptor (RXR) and retinoic acid receptor (RAR). It has neurotrophic functionality, promotes neuronal differentiation and may have therapeutic potential in treating stroke. It also regulates cytokine secretion and lymphocyte proliferation. 9cRA favors the dopamine cells survival and induces neuroprotection in neurodegenerative disorder like parkinson′s disease. It elicits anti-inflammatory function and stimulates mast cells and inhibits interleukin 4 and 5 expression levels. 9cRA is in clinical trial phase II for treating refractory cancer.
