Targeting the oncogenic activity of TCF3-HLF in leukemia.

Abstract

The oncogenic fusion transcription factor TCF3-HLF identifies an aggressive subtype of acute lymphoblastic leukemia. TCF3-HLF imposes a malignant program by activation of lineage-specific oncogenic enhancers. Among critical cofactors of the TCF3-HLF complex we identified EP300, which functional inhibition results in potent anti-leukemic activity by interference with the specific gene expression.
