digestive/alimentary system
• rectal prolapse is seen at a median time of 11 weeks of age
• 88% of mutants with colonic inflammation exhibit colon tumors; majority of tumors are invasive adenocarcinomas
• mutants exhibit a higher tumor burden (3-4 tumors per colon on average) than single Il10 homozygotes (1 tumor per colon)
• tumors develop as early as 8-12 weeks of age
• mutants develop segmental, patchy colon inflammation with areas of healthy-appearing colon adjacent to areas of severe inflammation
• mutants exhibit higher total colonic inflammation at 5-6 weeks of age than single Il10 homozygotes and show fewer fields of no inflammation
• neutrophils are the dominant cellular infiltrate in the colon which are not seen in the single Il10 homozygote
• mutants develop progressive inflammatory bowel disease much earlier than single Il10 homozygotes

neoplasm
• mice develop pancreatic tumors that can be grossly visualized at 9 weeks of age
• at 18 and 21 weeks, mice develop large solid tumor masses of less differentiated acinar cell carcinomas
• pancreas consists of acinar cell microadenomas
• pancreas consists of acinar cell carcinomas; well-differentiated acinar cell carcinomas are observed

endocrine/exocrine glands
• double transgenic mice exhibit acinar cell dysplasia at birth, which progresses to single or multiple cell acinar cell carcinomas
• increased pancreas weight is general indicator of tumor burden, but in many animals 15 weeks of age or older, pancreas weights do not increase presumably due to cachexia
• mice develop pancreatic tumors that can be grossly visualized at 9 weeks of age
• at 18 and 21 weeks, mice develop large solid tumor masses of less differentiated acinar cell carcinomas
• pancreas consists of acinar cell microadenomas

• nonimmunized mice develop anti-MUC1 cytotoxic T lymphocytes by 12 weeks and show 80% lysis of MUC1-expressing target cells by 18 weeks

immune system
• mice challenged with MUC1-expressing tumor cells do not develop IgM or IgG3 responses, and only 1 transgenic mouse showed an IgG1 antibody response, whereas most wild-type mice similarly challenged showed strong MUC1-specific IgM, IgG1, and half showed strong IgG3 responses
• in response to immunization with 5.25 copies of the MUC1 tandem repeat, wild-type mice generate strong responses in the IgM and all IgG isotypes, but transgenic mice show a strong IgM response but only weak IgG subtype responses
• following injection of a cre adenovirus in the ovarian bursa, mice exhibit an increase in the anti-MUC1 IgG response compared with un-injected Tg(MUC1)79.24Gend mice

neoplasm
• after injection of B16.9 melanoma cells, transgenic mice develop progressively growing tumors (average tumor volume 1.31 cm2) at day 26 postinjection
• tumor growth is significantly accelerated compared to injected wild-type mice where only 1 mouse had a tumor at 26 days postinjection; majority of wild-type mice have tumors at 34 days with an average volume of 0.11 cmL2
