SHIP is an inositol 5' phosphatase that hydrolyzes the PI3'K product PI(3,4,5)P3. We show that SHIP-deficient mice exhibit dramatic chronic hyperplasia of myeloid cells resulting in splenomegaly, lymphadenopathy, and myeloid infiltration of vital organs. Neutrophils and bone marrow-derived mast cells from SHIP-/- mice are less susceptible to programmed cell death induced by various apoptotic stimuli or by growth factor withdrawal. Engagement of IL3-R and GM-CSF-R in these cells leads to increased and prolonged PI3'K-dependent PI(3,4,5)P3 accumulation and PKB activation. These data indicate that SHIP is a negative regulator of growth factor-mediated PKB activation and myeloid cell survival.
