Abstract excerpt
Strategies to overcome resistance to FMS-like tyrosine kinase 3 (FLT3)-targeted therapy in acute myeloid leukemia (AML) are urgently needed. We identified autophagy as one of the resistance mechanisms, induced by hypoxia and the bone marrow microenvironment via activation of Bruton tyrosine kinase (BTK). Suppressing autophagy/BTK sensitized FLT3- mutated AML to FLT3 inhibitor-induced apoptosis. Furthermore,...
