Breast cancer is characterized by the accumulation of genetic
alterations, including point mutations and loss of entire DNA regions
("loss of heterozygosity" or LOH). Among genes that are affected by
such events, the "tumor suppressor genes" (TSGs) have a peculiar
interest since they often occupy pivotal positions in regulatory
networks that control the cell cycle and/or encompass various signal
transduction cascades. While a number of genes have been suggested as
candidate TSGs in breast cancer, only a few of them have been
confirmed in this status. They include TP53, BRCA1, BRCA2...and are
mainly involved in the control of DNA repair, cell proliferation,
apoptosis and signaling. Some TSGs are linked to familial (hereditary)
forms of breast cancer. The exact definition of what is a TSG is still
debated. Recently, genes not affected by mutation or even LOH, but
occasionally methylated have been considered as TSGs.
