The generation of transgenic mice overexpressing activated forms of oncogenes has greatly advanced our understanding into their roles in mammary tumor initiation, promotion and progression. However, targeted disruption of tumor suppressor genes often results in lethality at stages prior to mammary tumor formation. This obstacle can now be overcome using several approaches including conditional knockouts that delete genes of interest in a spatial and temporal manner. This review summarizes recent studies on tumor suppressor genes, including APC, ATM, BRCA1, BRCA2, PTEN and p53, in knockout mouse models and our understanding of the possible mechanisms underlying mammary tumorigenesis.
