BCL11B and acute lymphoblastic leukemia: In thymic T-ALL, BCL11b expression groups did not differ in the expression levels of molecular markers including BAALC, ERG, IGFBP7 and WT1. The BCL11b-low group showed significantly lower expression of T-cell regulator GATA3 compared to BCL11b-high (median Q1: 1.6, median Q2-4: 5.1, P < 0.01).
