DAD1 and leukemia: Probesets for KLF4 (2.26 fold difference, T-test P-value = 0.0177), BIRC5 (2 probesets with 1.65 and 1.64 fold differences with P values of 0.0006 and 0.0032 respectively), HSPA5 (1.60 fold difference, P-value = 0.0169), DAD1 (1.58 fold difference, P-value = 0.0130) and SYK (1.49 fold difference, P-value = 0.0196) exhibited significantly increased expression levels in leukemia cells from patients who experienced an early relapse vs. leukemia cells from patients who experienced a late relapse (Fig. 1B).
