Abstract
HER2 is a tyrosine kinase receptor, which is overexpressed in about 30% of breast cancer patients. Its overexpression leads to mammary tumorigenesis and increased invasion and metastasis (Slamon et al., 1987). HER2 transgenic mouse (FVB/N-MMTVneu mouse) is a well-established model of mammary tumor in human (Fantozzi and Christofori, 2006). Although in vivo models are excellent for assessing the influence of various factors, especially microenvironment, on development of breast cancer, a convenient and less costly way to study the underlying molecular events is utilizing cells derived from the model under evaluation. In order to explore the molecular mechanism by which HOXB7 inhibits initiation, but promotes metastasis of breast tumors, we generated mouse breast cancer cell line from HER2 transgenic mouse (Liu et al., 2015). This protocol may be useful for the generation of breast cancer cell line from mice with other genetic backgrounds.
