FLT3 and acute myeloid leukemia: The inverse correlation between N-CoR and Flt3 expression was also found to be translated to the protein level in the AML-M5 cell lines (Fig. 2B) as well as in multiple histologically confirmed primary AML-M5 patient samples (Fig. 2C), where both the 130 kDa intracellular non–glycosylated and the 160 kDa membrane bound glycosylated forms were observed to be highly expressed.
