digestive/alimentary phenotype ( J:152703 )
N
• unlike ApcMin heterozygotes, mice do not develop colonic polyps
intestine polyps ( J:152703 )
• mice develop fewer intestinal polyps compared to in ApcMin heterozygotes

neoplasm
decreased tumor incidence ( J:152703 )
• the number and size of microadenomas in the intestine are decreased compared to in ApcMin heterozygotes due to an increased in Caspase-3 dependent apoptosis
• mice fail to develop colon tumors unlike ApcMin heterozygotes

increased susceptibility to induced colitis ( J:152703 )
• following treatment with DSS, mice exhibit greater weight loss than similarly treated control mice and mild lesions with loss of mucus cells, glandular hyperplasia, and increased leukocyte levels in the lamina propria to severe lesions with complete loss of glandular epithelium, followed by collapse of denuded lamina propria, submucosal edema, fibrinoid necrosis of lamina propria vessels, and infiltration of neutrophils and plasma cells
