IQGAP1 and neoplasm: MmuPV1-infected Iqgap1−/− mice also had much lower tumor incidence than the MmuPV1-infected Iqgap1+/+ mice (33% vs. 80%), though this difference also did not quite reach the 95% confidence limit (Figure 3B. MmuPV1-infected Iqgap1+/+ vs. MmuPV1-infected Iqgap1−/−, p = 0.069, two-sided Fisher’s exact test).
