mortality/aging
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase have a median survival of 43 days

neoplasm
• tumors of Cre adenoviral treated mutants show transmural invasion of vessels and pleural invasion, and regional metastases to mediastinal lymph nodes
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase develop tumors similar to human mixed subtype adenocarcinomas; they show progression of a pure noninvasive lung adenocarcinoma to an adenocarcinoma with mixed invasive morphology and metastatic potential
• tumors of mutants treated with Cre adenovirus show evidence of inflammatory cell recruitment and tumor microenvironment remodeling with neoangiogenesis not seen in homozygous cre adenovirus treated Krastm4Tyj mice

hematopoietic system
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase exhibit and increase in B cells in the lungs compared to homozygous cre adenovirus treated Krastm4Tyj mice
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase exhibit and increase in T cells in the lungs compared to homozygous cre adenovirus treated Krastm4Tyj mice
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase exhibit a lower myeloid cell population in the lungs than controls

immune system
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase exhibit and increase in B cells in the lungs compared to homozygous cre adenovirus treated Krastm4Tyj mice
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase exhibit and increase in T cells in the lungs compared to homozygous cre adenovirus treated Krastm4Tyj mice
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase exhibit a lower myeloid cell population in the lungs than controls

respiratory system
• mutants with an intranasal instillation of an adenovirus expressing Cre recombinase develop tumors similar to human mixed subtype adenocarcinomas; they show progression of a pure noninvasive lung adenocarcinoma to an adenocarcinoma with mixed invasive morphology and metastatic potential
• tumors of mutants treated with Cre adenovirus show evidence of inflammatory cell recruitment and tumor microenvironment remodeling with neoangiogenesis not seen in homozygous cre adenovirus treated Krastm4Tyj mice
