neoplasm
increased lung adenocarcinoma incidence ( J:226601 )
• mice inhaling adenoviral particles expressing cre recombinase (AdCre) develop pan-cytokeratin-positive lung adenocarcinomas; about 85% of tumors show simultaneous activation of the three alleles
• lung tumors expressing all three alleles are slightly bigger than tumors not expressing all three alleles
• substantial percentage of triple allele activated tumors are invasive while non-triple allele activated tumors are noninvasive
• mice inhaling AdCre particles do not develop pancreatic or skin-appendage tumors
