Abstract:
:Individuals carrying germline mutations in one allele of the BRCA1 or BRCA2 genes are at significantly increased risk of developing cancer. Although the increased risk of breast cancer is often highlighted, cancer at several other sites is also considerably more common in these individuals. Here, we discuss existing knowledge of the role of BRCA1 and BRCA2 mutation in pre-disposition to ovarian cancer. The risk of an individual with a mutation developing cancer of the ovary appears to be influenced by the position of the mutation within the BRCA gene, the presence of allelic variants of modifying genes and the hormonal exposure of the carrier. Once cancer has developed, the pathology and clinical behaviour of BRCA-associated tumours is distinct from sporadic cases. Comparison of the pathogenesis of breast and ovarian cancers caused by BRCA mutation provides insight into the function of BRCA proteins as tumour suppressors in different cellular environments.

abstract::p53 is a tumor suppressor that responds to a variety of stresses such as oncogenes and DNA damage by activating its transcriptional targets to allow repair or elimination of damaged cells.
