Inhibition of p21ras activation blocks proliferation but not differentiation of interleukin-3-dependent myeloid cells.

Abstract excerpt

Interleukin-3 (IL-3) induces proliferation of immature myeloid cells and mast cells and prevents programmed cell death (apoptosis) in vitro. These activities are exerted through binding of IL-3 to specific, high affinity receptors that then initiate a series of intracellular signaling events. Among the earliest of these signaling events in an IL-3-dependent cell line such as 32Dcl3 are activation of one or more...
