TCGA data available from UALCAN demonstrated that the genes encoding PSMD2 (p = 0.046), PSMD6 (p = 0.03), PSMD7 (p = 0.046), and PSMD9 (p = 0.048) were found to be significantly upregulated in AML patients with mutated versus wild-type FLT3 (Figure 5A–D). Here, PSMD9 is linked to acute myeloid leukemia.
