N normal phenotype
mortality/aging
• mean survival time of double mutants is 21 weeks compared to 35 weeks for Kras+/-, Dmtf1-sufficient mice

neoplasm
• ~20% of mice develop thymic lymphomas
• 10-20% of animals develop tail papillomas
• all mice develop lung adenomas or lung adenocarcinomas
• greater than 50% of mice develop lung carcinomas by 40 weeks of age, and tumors are significantly larger than those found in KrasLA+/- single mutants
• number of tumor nodules increase as animals become sick, with trend to increased nodule size
• tumorigenesis is accelerated relative to heterozygous Kras, wild-type Dmtf1 mice

integument
• 10-20% of animals develop tail papillomas

endocrine/exocrine glands
• ~20% of mice develop thymic lymphomas

respiratory system
• all mice develop lung adenomas or lung adenocarcinomas
• greater than 50% of mice develop lung carcinomas by 40 weeks of age, and tumors are significantly larger than those found in KrasLA+/- single mutants
• number of tumor nodules increase as animals become sick, with trend to increased nodule size

immune system
• ~20% of mice develop thymic lymphomas

hematopoietic system
• ~20% of mice develop thymic lymphomas
