Dynamin-2 (DNM2) is a GTPase essential for intracellular vesicle formation and trafficking, cytokinesis and receptor endocytosis. Mutations in DNM2 are common in early T-cell precursor acute lymphoblastic leukemia. However, DNM2 expression in other types of ALL are not reported. We studied DNM2 mRNA level in adults with B- and T-cell ALL. We found DNM2 is more highly expressed compared with normals in both forms of ALL. High DNM2 expression is associated with some clinical and laboratory features, inferior outcomes and with leukaemia cell proliferation. We also found Ikaros directly binds the DNM2 promoter and suppresses DNM2 expression. Consequently IKZF1 deletion is associated with high DNM2 expression. Conversely, casein kinase-2 (CK2)-inhibitor increases Ikaros function thereby inhibiting DNM2 expression. Inhibiting DNM2 suppresses proliferation of leukemia cells and synergizes with CK2 inhibition. Our data indicate high DNM2 expression is associated with Ikaros dysregulation and may be important in the development of B-ALL.
