FOXM1 and leukemia: Concordant with these findings, in MA9-transformed leukemia cells in mice, we found that inhibition of FOXM1 by the FOXM1-specific peptide but not FOXM1-mutant peptide significantly reduced β-CATENIN expression in human leukemia cell lines including MV4-11, THP-1, and NOMO-1 cells as well as MA9.3 cells (Fig. 6g and Supplementary Fig. 7c).
