Nanoformulation of EPZ011989 Attenuates EZH2-c-Myb Epigenetic Interaction by Proteasomal Degradation in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a malignant disorder of hematopoietic progenitor cells with a poor prognosis of 26% of patients surviving 5 years after diagnosis. Poor bioavailability and solubility are significant factors limiting the efficacy of chemopreventive agents. In AML, the epigenetic regulator polycomb group of protein member EZH2 is highly expressed and is essential for the survival of leukemic cells.
