Although all SLD5+/−/Wnt1/C2mE as well as Wnt1/C2mE mice developed gastric cancer, the weights of the stomachs, including the tumor, in SLD5+/−/Wnt1/C2mE mice were significantly decreased compared to Wnt1/C2mE mice at this time (Figure 5Band Figure S1). The gene discussed is WNT1; the disease is gastric cancer.
