mortality/aging
• mice inoculated with an adenovirus expressing cre recombinase (ad-cre) by inhalation have a median survival of 9 weeks after ad-cre inoculation

neoplasm
• regional lymph-node metastases and axial skeleton metastases are seen in 61% of ad-cre inoculated mice
• mice inoculated with ad-cre develop lung tumors; tumor burden is increased at early time points and larger lesions at later time points are seen than in single Kras mutants
• adenocarcinoma is seen in all metastatic lesions
• 2 of 27 ad-cre treated mice show large cell carcinoma
• 56% of ad-cre treated mice develop squamous cell carcinomas (SCCs) or adenosquamous carcinomas
• squamous tumors do not express pro-surfactant protein, but express pan-keratin and p63, markers of SCC

respiratory system
• mice inoculated with ad-cre develop lung tumors; tumor burden is increased at early time points and larger lesions at later time points are seen than in single Kras mutants

• 56% of ad-cre treated mice develop squamous cell carcinomas (SCCs) or adenosquamous carcinomas
• squamous tumors do not express pro-surfactant protein, but express pan-keratin and p63, markers of SCC
