Analysis of IRF8 expression in GSE13425 showed that IRF8 expression levels were markedly lower in T‐ALL than in B‐cell acute lymphoblastic leukemia (B‐ALL) with cytogenetic subtypes such as TEL‐AML1, hyperdiploid, and BCR‐ABL (Figure 1B). This evidence concerns the gene IRF8 and B-cell acute lymphoblastic leukemia.
