Interests and Expertise

Abnormal cell growth in cancer cells results from genetic changes, such as amplifications, deletions, and mutations, that alter gene function. These genetic changes can be stimulated by stress during replication, the process of copying a cell's DNA. Replication stress, in which the copying process is slowed or stalled, causes breaks at particular hotspots known as "fragile sites," and many tumors have genetic changes at fragile sites. We use the yeast model system to investigate the fidelity of repair processes at fragile sites, analyze the contribution of fragile site instability to amplifications and deletions, and test hypotheses about why fragile sites are unstable during replication stress. The results of our studies will help us understand how and why genetic changes arise in tumor cells. For the most up-to-date information about my lab and the students working with me, please see my lab website: http://people.emich.edu/acasper2/
