ETS Fight Club on Microsatellite Enhancers


 In this issue of Blood Cancer Discovery, Kodgule, Goldman, Monovich et al. cleverly analyzed the transcription regulatory elements to investigate why the second copy of ETV6 is often lost in ETV6::RUNX1-translocated in B-cell precursor acute lymphoblastic leukemia (BCP-ALL). It turns out that ETV6 suppresses the enhancer activity of GGAA microsatellite repeats, preventing ERG from subverting them to activate aberrant oncogene transcription.
