6 Reversal of Tumor Growth by Induction of Redifferentiation Acute Promyelocytic Leukemia reverted to Neutrophils (stem-like) (ATRA) Possible Mechanism: Proteosome-mediated destruction of PML-RAR protein Also note: 13-cis-retinoic acid delays progression of premalignant mouth & throat to frank head-and- neck cancers.
