The FLT3 tyrosine kinase inhibitors such as midostaurin and quizartinib (AC220) have been successfully used for patients with FLT3 mutations in combination with chemotherapy in both the first-line and salvage therapy…. In conclusion, loss of miR-155 increased the treatment sensitivity to both chemotherapy and FLT3 inhibitors in FLT3-ITD+AML via glycolysis blocking by targeting PIK3R1.
