The results indicated that the expression levels of HOXA2, HOXA3, HOXA4, HOXA5, HOXA6, HOXA7, HOXA9, and HOXA10 were significantly increased in human AML patients compared to those in normal samples (P < 0.05), whilst the expression levels of HOXA1, HOXA11, and HOXA13 were not significantly different (Figure 2). Here, HOXA10 is linked to acute myeloid leukemia.
