Identification of therapeutic targets of the hijacked super-enhancer complex in EVI1-rearranged leukemia (4C-Seq)
Chromosomal aberrations in acute myeloid leukemia (AML), such as inv(3) and t(3;3), lead to deregulation of the EVI1 oncogene by the GATA2 distal hematopoietic enhancer (G2DHE). In this project, we aimed to study the transcription factor complexes involved in the regulation of the G2DHE sequence. We identified PARP1 as an interactor of G2DHE-associated transcription factors. In this dataset, we studied the interaction of genomic loci between the EVI1 promoter and G2DHE by 4C-Seq in the 3q-rearranged AML cell line MUTZ-3 treated with the PARP1 inhibitors olaparib, talazoparib or the DMSO vehicle control for 24 h. Overall design: MUTZ-3 cells were treated with PARP1 inhibitors and the genomic interactors of the EVI1 promoter locus were captured by 4C-Seq.
