mortality/aging

premature death ( J:126002 )

• mean survival time of double mutants is 21 weeks compared to 35 weeks for Kras^+/-, Dmtf1-sufficient mice

neoplasm

increased T cell derived lymphoma incidence ( J:126002 )

• ~35% of mice develop thymic lymphomas

increased skin papilloma incidence ( J:126002 )

• 10-20% of animals develop tail papillomas

abnormal metastatic potential ( J:126002 )

• <5% of animals show distant metastases (liver/intr-abdominal or leg) of lung tumors, while no metastases are observed in Kras^LA+/-, Dmtf1-sufficient mice

increased lung tumor incidence ( J:126002 )

• ~50% of largest tumors are well, moderately, or poorly differentiated adenocarcinomas, with signs of intrabronchial or intravascular invasion

increased lung adenoma incidence ( J:126002 )

• all mice develop lung adenomas or lung adenocarcinomas

increased lung adenocarcinoma incidence ( J:126002 )

• greater than 50% of mice develop lung carcinomas by 40 weeks of age, and tumors are significantly larger than those found in Kras^LA+/- single mutants

• number of tumor nodules increase as animals become sick, with trend to increased nodule size

decreased tumor latency ( J:126002 )

• tumorigenesis is accelerated relative to heterozygous Kras, wild-type Dmtf1 mice
