IL-7 is not known to be expressed in AML; however, ZEB2 has been demonstrated to modulate other myeloid-relevant cytokines such as IL-6 and G-CSF [128], and SNAI1 may enhance TNF/NFkb signaling [163], which may activate similar pro-survival pathways in AML. This evidence concerns the gene ZEB2 and acute myeloid leukemia.
