Excerpt
Several cytogenetic studies demonstrated frequent allelic losses at defined regions on chromosome 6 in breast tumors, suggesting the presence of tumor suppressor gene(s) (TSG) contributing to breast cancer (BC) tumorigenesis. Different techniques identified several candidate TSGs on chromosome 6 in BC, but no functional evidence for a TSG function for these genes could so far be supplied. In order to identify key genes and elucidate the regulatory pathways that are involved in the development and progression of BC, we combined array-based expression profiling with a powerful functional approach, the microcell-mediated chromosome transfer. …
