Introduction: Nuclear retinoid receptors (RARs) upon a ligand binding act as all-trans retinoic acid-inducible transcription factors interacting as heterodimers with nuclear retinoid X (rexinoid) receptors (RXRs). The disruption of retinoic acid (RA) signalling pathways is believed to underlie the etiology of a number of malignancies. Retinoids – cell differentiation agents that may ‘reprogram’ tumours, i.e. retinoic acid derivatives or retinoic acid related com...

Retinoid receptors (RARs) upon a proper ligand binding act as all-trans retinoic acid-inducible transcription factors interacting as heterodimers with retinoid X receptors (RXRs). Predominantly, novel synthetic retinoid analogues acting through RARs as redifferentiation agents would be of great value in treating patients with advanced thyroid cancer.The objective of this study was to investigate all-trans retinoic acid/9-cis retinoic acid n...
