Compared to controls, MMTV-Wnt1;MMTV-Wnt5a mice showed reduced incidence of tumor formation (Figure 1A; 60% vs 22%, p-value = 0.001) and a 6- to 7-week delay in earliest detection of palpable tumors (Figure 1B; n = 22 MMTV-Wnt1, n = 25 MMTV-Wnt1;MMTV-Wnt5a, p-value = 0.0045). Here, WNT5A is linked to neoplasm.
