As suggested from our previous observations [10], 9.52% of these primary human samples (4/42; AML11463, AML17358, AML10705 and AML11353) as well as cells from four PDX models AML#10 1st, AML#10 2nd, AML9276 1st and AML9276 2nd expressed a full length FGFR1 kinase. The gene discussed is FGFR1; the disease is acute myeloid leukemia.
