As shown in Fig. S6, the expression of ITGA6 was significantly higher in the 12 cases of EVI1high AML than in the 10 cases of EVI1low AML (p<0.05); however, the differences in expression of ITGB4, ITGA4 and ITGB1 did not account for the differences between the two groups. This evidence concerns the gene ITGA6 and acute myeloid leukemia.
