Comparisons of the expression levels of

DNMTs between the AML groups with or withoutp15^INAK4B methylation. The levels of DNMTs were corrected by GAPDH (A-C) orPCNA (D-F). The level of DNMT1 corrected byGAPDH is significantly higher in the group with methylatedp15^INAK4B than in the group with unmethylatedp15^INAK4B (A) (P = .0147). Comparisons were made by the Mann-Whitney U test. M indicates methylated cases; U, unmethylated cases.
