We took advantage of a primary murine AML transplantation model based on the combined overexpression of Hoxa9 and Meis1 (H9M)...To evaluate the effect of INT-1B3 on leukemogenesis in vivo, we engrafted H9M cells in a murine host with an intact immune system, allowing INT-1B3 to exert its immunomodulatory effects. Biweekly i.v. treatments of INT-1B3 after H9M cell transplantation prevented AML formation, highlighting the potent anti-leukemic activity of this miRNA based therapeutic...
