Molecular Genetics Of Breast Cancer, Emel Ergül, Ali̇ Sazci

Turkish Journal of Medical Sciences

Recent advances in molecular biology enable researchers to understand the basis of breast cancer much better and show that hereditery breast cancer may result from mutations on several specific gene loci including BRCA1, BRCA2, p53, ATM and PTEN. These genes are tumor supressor genes and although their functions are different, they are all involved in the maintenance of genomic stability after DNA damage. Mutations that impair the function of these genes may adversely affect the manner in which DNA damage is processed. It is likely that the risk of breast cancer development is increased through this mechanism. Moreover, there are …
