Abstract excerpt
Carcinoma induction in the rat mammary carcinogenesis model is age dependent. In this study, mammary cancer susceptibility and ras gene activation were investigated in rats exposed to N:-methyl-N:-nitrosourea (NMU) at 2, 6, 8 and 15 months. Animals were resistant to NMU-induced mammary tumor development when exposed at 6 and 8 months of age, whereas a significant number of mammary carcinomas developed in animals...
