DAB2 and acute myeloid leukemia: Comparing the geometric mean fluorescence intensity (gMFI) of GFP, a surrogate for the level of ectopic DAB2 expression, between mice that did and did not develop AML/MPD, we noted a trend towards increased fluorescence in the DAB2-AML/MPD group (P = 0.06) (Supplementary Fig. 4e).
