| Summary |
5 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• tamoxifen-treated mice show reduced density of alveoli
|
|
• alveoli are enlarged in tamoxifen-treated mice
|
|
• adult mice treated with tamoxifen exhibit enlargement of alveolar airspace and loss of alveolar density, indicating emphysematous changes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• many mice do not survive to 13 weeks after tamoxifen treatment due to high tumor burden
• mice display leaky cre expression without tamoxifen treatment and survive a few months longer than tamoxifen-treated animals
|
|
• after tamoxifen treatment, mice show a more severe phenotype than animals with wild-type Trp53 (greater tumor size, tumor growth and tumor grade); by 3-4 weeks after tamoxifen treatment, several small adenomas of papillary nature are observed in alveoli
• at 10 weeks after tamoxifen injection, many alveoli have large tumors; tumors exhibit enlarged pleomorphic nuclei, aberrant mitosis; tumor giant cells are present
|
|
• mice surviving to 13 weeks after tamoxifen treatment have adenocarcinomas in the alveoli of the lungs
• without tamoxifen treatment, mice develop invasive lung adenocarcinomas localized to the alveoli
• bronchioalveolar duct junctions (BADJs) appear normal ( in mice with or without tamoxifen treatment)

• without tamoxifen treatment, mice develop invasive lung adenocarcinomas localized to the alveoli
• bronchioalveolar duct junctions (BADJs) appear normal ( in mice with or without tamoxifen treatment)
|
|
• 8 days after tamoxifen treatment, extensive type II cell proliferation is observed compared to wild-type; however, proliferating bronchioalveolar stem cells (BASCs) are rarely observed (at 8 days, 3, 6, 10 and 13 weeks after tamoxifen treatment)
• tumor cells express type II cell markers and are highly proliferative, even without tamoxifen treatment
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• by 18 weeks after tamoxifen treatment, numerous adenomas develop in alveoli; small numbers of cells with features of malignant transformation are observed in some lung sections
• tumors are usually found in proximity to the airways, bronchioalveolar duct junctions (BADJs), or surface of the lung, but lesions are not found in the BADJs
• tumor cells are highly proliferative
• airways and BADJs retain normal architecture

|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• mice die 14 weeks or less after tamoxifen administration
|
|
• at 6-8 weeks of age, animals administered 1dose or 4 doses of tamoxifen develop widespread adenomas in the alveoli by 14 weeks of age, but the bronchoalveolar duct junction remains tumor-free
|
|
• at 6-8 weeks of age, animals administered 1dose or 4 doses of tamoxifen develop widespread adenocarcinomas in the alveoli by 14 weeks of age
|
|
• at 6-8 weeks of age, animals administered 1dose or 4 doses of tamoxifen develop widespread adenomas in the alveoli by 14 weeks of age, but the bronchoalveolar duct junction remains tumor-free
|
|
• at 2 weeks after tamoxifen treatement, brochioalveolar duct junctions (BADJ) appear normal, but small adenomas occur in the alveoli; these progress to adenocarcinoma but the BADJ remain histologically normal
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
| N |
• bleomycin, tamoxifen-treated mice develop fibrosis and lung collagen content as in control mice
