ABSTRACT
GEN1, a Holliday junction resolvase, is involved in homologous repair of DNA double strand break and in maintaining centrosome integrity. Although GEN1 mutants have been reported in breast cancer patients and cell lines, little is currently known about the functions of GEN1 in the development and oncogenic transformation of mammary gland. In the present study, we demonstrate that GEN1 expression is correlated with mammary epithelial cell proliferation, differentiation in various physiological stages as well as casein. By immunofluorescence analysis, the centrosomal association of GEN1 is confirmed in mammary epithelial cells. Additionally, GEN1 is likely involved in DNA damage response of breast cancer cell lines. These results suggest that GEN1 may play an important role in the development of mammary gland; its response upon DNA damage indicates that GEN1 gene alteration may contribute to breast cancer formation.
