beta-Ionone (ION), an end-ring analogue of beta-carotenoid, has been known to inhibit tumor cell growth and induce apoptosis in various types of cancer cells. Nevertheless, its apoptosis-related molecular mechanisms remain unclear. Here, we first investigated the molecular mechanisms by which ION
All-trans retinoic acid (ATRA) induces remission in patients with acute promyelocytic leukaemia. Other retinoids, including 9-cis- and 13-cis-retinoic acid (9-cis- and 13-cis-RA), are now being evaluated for their therapeutic potential. The elimination of ATRA is partially dependent on cytochrome
