FLT3 and acute myeloid leukemia: When we compared phosphotyrosine profile between two FLT3-ITD cell lines (MV(4;11) and Molm 14) and three FLT3-ITD AML patients, we noticed that 77% (130 out of 168) of phosphoproteins identified in AML patients were also present in these two cell lines, suggesting that FLT3-ITD cell lines are good models to understand FLT3-ITD signaling for primary patients (Figure S3).
