Role of the Wnt-4 Protein in the Mouse Mammary Gland

Abstract

The subject of the research described within this report is the mouse BRCA1 protein. The primary purpose of the experiments outlined below is to further the understanding of the role the mouse BRCA1 protein in cell proliferation and DNA damage. The scope of this research encompasses experiments that are designed to determine if the mouse and human BRCA1 proteins govern similar cellular functions and aims to identify novel regulatory components implicated in BRCA1-derived cancers through the use of a genetic model system in which mouse BRCA1 is mutated. An immortalized mouse embryonic fibroblast cell line that harbors an exon 11 mutant form of Brca1 has been generated. We have generated several murine Brca1 antibodies and have characterized the expression of the exon 11-deleted Brca1 protein in these cells. Significantly, this protein localizes to nuclear foci during S phase. We have also demonstrated that the exon 11 region of Brca1 is required for efficient Rad51 foci formation in response to gamma radiation.
