The other screened for DEG in Reh, an ETV6::RUNX1‐positive ALL cell line, comparing EP300‐Z‐transfected Reh and control Reh, and selected GATA321; however, GATA3 was not upregulated in TCF3‐Z/LCL or TAF15‐Z/LCL in our study, probably due to the difference of the Z‐fusion gene used. This evidence concerns the gene ETV6 and acute lymphoblastic leukemia.
