In the analyzed data set of adult AML patients, we found that MELK expression was strongly correlated with that of FOXM1 (Spearman's rank correlation is 0.75), CCNB1 (Spearman's rank correlation is 0.79), and BIRC5 (Spearman's rank correlation is 0.70); weaker correlation was found with CDC25B (Spearman's rank correlation is 0.46) (Figure 7A, B, C and D). Here, CCNB1 is linked to acute myeloid leukemia.
