Key Points

Key Points The PAFc subunit, Cdc73, is required for the proliferation and proper epigenetic regulation of proleukemic oncogenes in AML cells. Disrupting the MLL-PAFc interaction selectively inhibits the growth of MLL-associated leukemic cells without altering normal hematopoietic stem cell function.
