This review focuses on genes other than the high penetrance genes BRCA1 and BRCA2 that are involved in breast cancer susceptibility. The goal of this review is the discovery of polymorphisms that are either associated with breast cancer or that are in strong linkage disequilibrium with breast cancer causing variants. An association with breast cancer at a 5% significance level was found for 13 polymorphisms in 10 genes described in more than one breast cancer study. Our data will help focus on the further analysis of genetic polymorphisms in populations of appropriate size, and especially on the combinations of such polymorphisms. This will facilitate determination of population attributable risks, understanding of gene-gene interactions, and improving estimates of genetic cancer risks.

Ionizing radiation is known to improve transfection of exogenous DNA, a process we have termed radiation-enhanced integration. Previous observations have demonstrated that Ku proteins are critical for radiation-enhanced integration. Since Ku proteins form the DNA-binding domain of DNA-PK and since DNA-PK is important in nonhomologous DNA end joining, it was hypothesized that DNA-PK function might be important for radiation-enhanced integration. The ATM protein has been shown to be important in the recognition of a variety of types of DNA damage and to associate with DNA-PK under certain conditions. It was thus hypothesized that ATM might also play a role in radiation-enhanced integration. To test these hypotheses, radiation-enhanced integration was measured in hamster cells that are defective in the catalytic subunit of DNA-PK and in human cells containing mutant ATM. Radiation-enhanced integration was not detected in any of the cell lines with mutant PRKDC (also known as DNA-PKcs), but it was present in cells of the same lineage with wild-type PRKDC. Radiation-enhanced integration was defective in cells lacking kinase activation. ATM-deficient cell lines also showed defective radiation-enhanced integration. These data demonstrate that DNA-PK and ATM must both be active for radiation-enhanced integration to be observed.
