Lungs of Xpctm1Ecf/Xpctm1Ecf mice show a range of lesions
|
• lung tumors are seen as early as 6 months of age and by 16-17 months of age, all mutants develop tumors
• incidence and multiplicity of lung tumors increases with age
|
|
• most lung tumors are classified as adenomas, with only a few progressing to malignant carcinomas

|
• cyclobutane pyrimidine dimers are observed in hair follicles after treatment with a total UV dose of 1.0 kJ/m2
|
|
• basal cells exhibit hypoplasia after a total UV dose of 1.0 kJ/m2 despite the dose being much below the minimal erythema dose
|
|
• cyclobutane pyrimidine dimers are observed in cells within the dermis at a reduced level (4.7% compared to 12% in wild-type mice) after treatment with a total UV dose of 1.0 kJ/m2
• pyridine pirimidone photoproducts accumulate in about 1.8% of epidermal basal cells after treatment with a total UV dose of 1.0 kJ/m2 and no increase in photoproducts with increased exposure

|
• at 24 months of age, only 28% of mutants are alive compared to 43% of wild-type
|
|
• some mutants exhibit malignant adenocarcinoma with metastasis to adjacent lymph nodes
|
|
• 100% of mutants develop lung tumors by 24 months of age; display a full range of lung lesions, ranging from mild atypia and hyperplasia to malignant adenocarcinoma with metastasis to adjacent lymph nodes
|
|
• majority of mutants develop lung adenocarcinomas coincident with adenomas
