Phosphoproteomics of primary human FLT3-ITD+ AML cells treated with gilteritinib


ABSTRACT: Primary human AML cells (newly diagnosed, prior to treatment initation) were obtained from donor after consent and AML blasts were isolated by standard Ficoll centrifugation. AML blasts were treated with FLT3 inhibitor gilteritinib (or DMSO vehicle control) at 10 nM concentration for 6 h, followed by harvest for LC/MS.

Internal tandem duplications (ITD) in the receptor tyrosine kinase FLT3 occur in 25 % of acute myeloid leukemia (AML) patients, drive leukemia progression and confer a poor prognosis. Primary resistance to FLT3 kinase inhibitors (FLT3i) quizartinib, crenolanib and gilteritinib is a frequent clinical challenge and occurs in the absence of identifiable genetic causes. This suggests that adaptive cellular mechanisms mediate primary resistance to on-target FLT3i therapy. Here, we systematically inve  ...[more]
