We compared the tumorigenic effects of the N-ras oncogene and the N-ras proto-oncogene in lymphoid and mammary tissues in an in vivo model. For this purpose, we generated transgenic mice with high levels of N-ras oncogene or N-ras proto-oncogene expression, driven by the complete mouse mammary tumor virus LTR (MMTV-LTR) (MMTV/N-rasT and MMTV/N-rasN constructs) and transgenic mice with low levels of N-ras oncogene or N-ras proto-oncogene expression, driven by a truncated MMTV-LTR (TMTV/N-rasT and TMTV/N-rasN constructs). We show that both, the N-ras proto-oncogene and the N-ras oncogene with a C:G-->A:T mutation at codon 61, lead to identical tumor types: lymphoblastic T-cell lymphomas, cleaved B-cell lymphomas and poorly differentiated mammary carcinomas. Nevertheless, there were quantitative differences in tumor incidence and latency and in transgene expression among N-ras oncogene and N-ras proto-oncogene transgenics. Despite these differences in tumor kinetics, the predisposition to identical tumor types is in agreement with the idea that the N-ras oncogene and the N-ras proto-oncogene act through the same pathway for in vivo tumorigenesis in B-cells, T-cells or mammary epithelial cells.
