Title	Oncogene EVI1 Drives Acute Myeloid Leukemia Via a Targetable Interaction with CTBP2
Description	Acute myeloid leukemia (AML) driven by the activation of EVI1 due to chromosome 3q26/MECOM rearrangements is incurable with current chemotherapy regimens. Insight into the mechanism by which EVI1 drives myeloid transformation is needed to target EVI1 in those leukemias. Here we demonstrate recurrent interaction of CTBP1/2 with a unique PLDLS motif in EVI1, which is indispensable for leukemic transformation of 3q26/MECOM rearranged AML. A PLDLS competitor construct outcompetes EVI1 to CTBP1/2 binding and inhibits AML proliferation in xenotransplant models. This proof-of-concept study opens the possibility to target one of the most incurable forms of AML using specific inhibitors directed to EVI1/CTBP1/2 interaction. Our findings have important implications for other tumour types with aberrant expression of EVI1 or other oncogenic transcription factors that also depend on CTBP1/2 interaction.
