Table 1 combines the tumor data from both time points and breaks it down according to tumor type, location, number, and expression patterns of β-catenin. Overall, 45% (14/31) of the Vil-Cre-ERT2/p120 KO mice examined at 12 or 18 months developed tumors while none were detected in age matched control (n = 29) animals. The tumors occurred in the small intestine or the cecum and were classified as one of four types by expert pathologist, Dr. M.K. Washington: small adenoma (Figure 5A), adenoma (Figure 5B), adenocarcinoma (Figure 5C), and mucinous adenocarcinoma (Figure 5D). The gene discussed is MAPK3; the disease is mucinous adenocarcinoma.
