Abstract excerpt
To elucidate which is the major determinant of susceptibility of p53 deficient mice, the carcinogen or the target organ, N-bis(2-hydroxypropyl)nitrosamine was administered to induce tumors in multi-organs. In a 15-week experiment, the incidences of both lung and hepatic vascular tumors were found to be significantly higher in p53 nullizygous (-/-) than in heterozygous (+/-) and wild-type (+/+) mice, indicating...
