Summary of the expression levels of

DNMTs in AML and CML measured by competitive PCR.Expression levels of DNMTs, corrected by the levels ofGAPDH (A-C) or PCNA (D-F) transcripts are shown. The Kruskal-Wallis test with the Bonferroni method for multiple comparison was used to compare the levels of each DNMT in different sample categories. *, ** indicates statistical significance (*, P < .05; **, P < .01).
