Targeting epigenetic networks mediated by Prmt1 and Kdm4c in acute myeloid leukemia


ABSTRACT: Transcriptional deregulation plays a major role in acute myeloid leukemia, identification of epigenetic modifying enzymes essential for the maintenance of oncogenic transcription programs holds the key to better understanding the biology and designing effective therapeutic strategies for the disease. Here we provide experimental evidence showing the functional involvement and therapeutic potentials of targeting PRMT1 with H4R3 methyltransferase activity in various MLL and non-MLL leukemias. PRMT1 is necessary but not sufficient for leukemic transformation, which requires co-recruitment of KDM4C with H3K9 demethylase activity by chimeric transcription factors to mediate epigenetic reprogramming. Inhibition of KDM4C/PRMT1 suppresses transcription and transformation ability of MLL fusions and MOZ-TIF2, revealing a novel and targetable epigenetic circuitry mediated by PRMT1 and KDM4C in acute leukemia.
