To examine the similarity in expression dynamics between miRNA and mRNA further, we calculated correlation coefficients between miRNAs and five mRNAs identified to have a large contribution to AML in our previous work (Prkd1, Egfl7, Wt1, Kit, and Cbfb-MYH1l) (13) and performed hierarchical clustering on the correlation matrix. Here, CBFB is linked to acute myeloid leukemia.
