Targeting the HTLV-I-Regulated BATF3/IRF4 Transcriptional Network in Adult T Cell Leukemia/Lymphoma

Abstract
• BATF3 and IRF4 are master regulators of ATLL gene expression and proliferation • HBZ drives BATF3 expression by binding to a super-enhancer in the BATF3 locus • BET inhibitors collapse the transcriptional network directed by HBZ and BATF3/IRF4 • BET inhibitors are toxic for ATLL cells ex vivo and block ATLL xenograft growth
