A Target-Specific Cellular Assay for Screening of Topoisomerase I Inhibitors.

We have developed a cellular, target-specific high-throughput assay for the detection of topoisomerase I inhibitors. Topoisomerase I is a nonessential enzyme involved in controlling DNA topology. Topoisomerase I is the target of anticancer drugs such as camptothecin as well as a candidate target for new antifungal drugs. A wild-type Saccharomyces cerevisiae… CONTINUE READING
