CSF3R and neoplasm: In vivo neutralization of IFNγ caused a dramatic increase of tumor incidence in Csf3r+/+ mice as previously reported (Kaplan et al., 1998, Koebel et al., 2007, Shankaran et al., 2001), but not in Csf3r−/− mice (Figure 2F), abolishing the difference in sarcoma susceptibility between Csf3r+/+ and Csf3r−/− control mice.
