Biochem/physiol Actions

13-cis-Retinoic acid (RA) has anti-inflammatory and anti-tumor action. The action of RA is mediated through RAR-β and RAR-α receptors. RA attenuates iNOS expression and activity in cytokine-stimulated murine mesangial cells. It induces mitochondrial membrane permeability transition, observed as swelling and as a decrease in membrane potential, and stimulates the release of cytochrome c implicating mechanisms through the apoptosis pathway. These activities are reversed by EGTA and cyclosporin A. RA also increases MMP-1 protein expression partially via increased transcription.
