A carcinogen may have specific mechanisms for inducing tumors, which may involve inducing characteristic gene expression alterations. In this study, we attempted to identify genes crucial for mammary carcinogenesis. For this purpose, we used human c-Ha-ras proto-oncogene transgenic rats (Hras128), which are highly sensitive to mammary carcinogens including N-methyl-N-nitrosourea, 7,12-dimethyl benz[a]anthracene, and 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine. DNA microarray analysis revealed that glutathione peroxidase 2 (Gpx2) was commonly up-regulated in the mammary carcinomas induced by the three different carcinogens, and its up-regulation was confirmed by quantitative reverse transcriptase-PCR and Western blotting analysis. In addition, expression of GPX2 was recognized in all 41 immunohistochemically examined cases of human breast cancer. Forced suppression of GPX2 expression by siRNA resulted in significant growth inhibition in both rat and human mammary carcinoma cell lines with wild-type p53 cells. Thus, these data suggested that GPX2 may be involved in mammary carcinogenesis and cell proliferation in both rats and humans, indicating that GPX2 may be a novel target for the prevention and therapy of breast cancer.
