FLT3

Fms-like tyrosine kinase 3 (FLT3) is a tyrosine kinase that is expressed in early hematopoietic progenitor cells, including CD34+ cells.1,2 Binding the FLT3 ligand activates multiple cell signaling pathways, including proliferation and survival in early blood cells.2

FLT3 is overexpressed in leukemic blast cells in >70% of patients with acute myeloid leukemia (AML), irrespective of CD34+ status, which suggests that FLT3 plays a key role in the survival or proliferation of leukemic blast cells.1,3

Therapies targeting FLT3 may be a novel therapeutic approach for treating AML.
