In that study, BRD4 was enriched at hallmark genes implicated in CLL disease biology and progression such as genes associated with BCR pathways (e.g., BTK, BLK, SYK, PLCG2, and PIK3CG), ZAP70, CXCR4, MIR155, IL4R, IL21R, IKZF1, and TCL1A [30]. Here, BCR is linked to B-cell chronic lymphocytic leukemia.
