• N: normal phenotype

digestive/alimentary system

increased intestinal adenoma incidence ( J:301471 )

• at 6-8 months of age, 83% of mice show symptoms of neoplasia (rectal bleeding, anemia, splenomegaly) and 1 or more macroadenomas in the intestinal tract relative to 56% in Apc^tm1Cip heterozygotes

• a greater % of mice develop 51 to 100 or over 100 polyps (all sizes) in the intestinal tract, and the average number of tumors per mouse is ~3-fold higher than that in Apc^tm1Cip heterozygotes

neoplasm

increased intestinal adenoma incidence ( J:301471 )

• at 6-8 months of age, 83% of mice show symptoms of neoplasia (rectal bleeding, anemia, splenomegaly) and 1 or more macroadenomas in the intestinal tract relative to 56% in Apc^tm1Cip heterozygotes

• a greater % of mice develop 51 to 100 or over 100 polyps (all sizes) in the intestinal tract, and the average number of tumors per mouse is ~3-fold higher than that in Apc^tm1Cip heterozygotes

increased tumor growth/size ( J:301471 )

• mice develop more tumors, esp. larger ones, in the intestinal tract; the average number of macroadenomas (>5 mm) per mouse is ~3-fold higher than that in Apc^tm1Cip heterozygotes

• however, no differences in tumor grade, aggressiveness or proliferation are observed
