Treatment Shapes Clonal Evolution and Resistance Patterns in Murine KMT2A-Rearranged Leukemia with Subclonal FLT3 N676K

Our understanding of how individual mutations, whether present in all or just a fraction of the leukemia cells, affect cellular responses to therapy is limited. Leukemia mouse models provide a unique possibility to explore how therapy affects the evolution of genetically distinct clones and identify mechanisms of resistance allowing transfer to human disease. Herein, we studied how different therapies influenced survival, clonal evolution, and resistance patterns in mouse KMT2A-MLLT3 leukemia with subclonal FLT3 N676K.
