Two methods of treatment where this is especially important to consider are topoisomerase inhibitors and nucleoside analogues. In both of these cases, DNA repair systems involve the use of the Mre11/Rad50/NBS1 complex. This project aims to examine how DNA repair mechanisms of Schizosaccharomyces pombe contribute to resistance to treatment with nucleoside analogues. This information should help to provide further insight into the way in which human cells are able to develop resistance to this form of treatment, and perhaps provide some indication of a method to prevent this.
