Abstract excerpt
In the present study, susceptibility of CB6F1 mice carrying the human prototype c-Ha-ras gene (rasH2 mice) and p53 gene knockout mice (p53 (+/-) mice) to urethane-induced lung carcinogenesis was compared under the same experimental conditions. Both strains were administered 500 ppm urethane in their drinking water for 3 weeks. At week 26, lung adenocarcinomas and adenomas were observed in 53% and 100% of rasH2...
