As shown in Figure 1, the relative expression levels of BMPR2, EP300, and TNFAIP3 mRNA in the cell lines from B-cell malignancy were significantly higher than those cell lines from myeloid leukemia (P<0.05), whereas the relative expression levels of TGFβ2 mRNA showed no significant difference between B-cell malignant cell lines and myeloid leukemia cell lines (P>0.05). Here, EP300 is linked to myeloid leukemia.
