BCL11B and acute lymphoblastic leukemia: As previously reported [24], the BCL11B mRNA expression level in PBMCs from patients with T-ALL (median: 389.04 copies/105β2M copies, mean rank: 26.56, P < 0.001) was significantly higher than that in patients with B-ALL (median: 30.39 copies/105 β2M copies, mean rank: 7.69) (Fig. 1b).
