Arsenic-induced PML targeting onto nuclear bodies: Implications for the treatment of acute promyelocytic leukemia

Abstract excerpt

Acute promyelocytic leukemia (APL) is associated with the t(15;17) translocation, which generates a PML/RAR alpha fusion protein between PML, a growth suppressor localized on nuclear matrix-associated bodies, and RAR alpha, a nuclear receptor for retinoic acid (RA). PML/RAR alpha was proposed to block myeloid differentiation through inhibition of nuclear receptor response, as does a dominant negative RAR alpha...
