In primary cells of a cohort of 833 adults, array data showed that XIAP mRNA was upregulated in ALL compared to healthy controls and expressed to a higher level than in AML (Figs 3A and EV2A), while c‐IAP1/2 mRNAs were not significantly increased in ALL (Fig EV2B–E). The gene discussed is XIAP; the disease is acute myeloid leukemia.
