Molecular variability of FLT3/ITD mutants and their impact on the differentiation program of 32D cells

ABSTRACT: FLT3 is the most frequently mutated gene in AML – up to 40% of AML harbor an activating mutation within FLT3 gene. Though AML is a relatively rare disease, such a high mutability rate, as observed with FLT3 gene, is striking. To elucidate the molecular background of this phenomenon, we have established nine unique FLT3/ITD - carrying 32D cell lines and a set of controls, and subjected them to whole genome expression analysis and 2DE LC/MS proteomics. Data obtained on this so far largest set of ITD mutants indicates that in comparison to the wild type FLT3 expressing 32D cells and transduction controls, FLT3/ITD positive cells exhibit less mature expression profiles resembling ST-HSC and MkEP/CMP/LMPP progenitors. We hypothesize that FLT3/ITD might contribute not only to the proliferative
