We’ve got previously described FLT3-ITD-dependent phosphorylation of CSF2RB, the typical receptor beta chain of IL-3, IL-5, and GMCSF, and as a result examined its significance for FLT3-ITD-dependent oncogenic signaling and transformation. We discovered that FLT3-ITD directly binds to CSF2RB in AML cell lines and blasts isolated from AML individuals. A knockdown of CSF2RB in FLT3-ITD positive AML cell lines too as in a xenograft model decreased STAT5 phosphorylation, attenuated cell proliferation, and sensitized to FLT3 inhibition.PMID:28630660 Bone marrow from CSF2RB-deficient mice transfected with FLT3-ITD displayed decreased colony formation capacity and delayed disease onset together with increased survival upon transplantation into lethally irradiated mice. FLT3-ITD-dependent CSF2RB phosphorylation expected phosphorylation of the FLT3 juxtamembrane domain at tyrosines 589 or 591, whereas the ITD insertion site and sequence had been of no relevance. Our outcomes demonstrate that CSF2RB participates in FLT3ITD-dependent oncogenic signaling and transformation in vitro and in vivo. Therefore, CSF2RB constitutes a rational therapy target in FLT3-ITD-positive AML. Leukemia (2022) 36:70111; doi.org/10.1038/s41375-021-01462-1234567890();,:INTRODUCTION The int.
