neoplasm
• after 3 weeks, mice treated with adenovirus cre via intranasal delivery and exposed to tamoxifen develop multiple hyperplastic and dysplastic epithelial foci with pseudotratification and occasional micropapillary tuft formation in the lungs unlike in similarly treated wild-type mice
• after 6 weeks, mice treated with adenovirus cre via intranasal delivery and exposed to tamoxifen exhibit extensive micropapillary and papillary hyperplasia with several bronchioles exhibiting Clara cell hyperplasia and sloughing into the airway lumen unlike similarly treated wild-type mice

neoplasm
• following intranasal treatment with adenovirus cre only, mice exhibit hyperplastic and dysplastic bronchiolar lesions unlike similarly treated wild-type mice but similar to in cre-activated Krastm4Tyj homozygotes
• 6 weeks following intranasal exposure to adenovirus cre and treatment with tamoxifen, mice develop large and numerous papillary adenomas that are poorly differentiated and grow in small tumor clusters with individual cells embedded within desmoplastic stroma
• 6 weeks following intranasal exposure to adenovirus cre and treatment with tamoxifen
