Yeast chemical genetic screen for inhibitors of human telomerase

A yeast chemical genetic screening assay for small molecule inhibitors of human telomerase could help identify new leads to treat telomerase-positive cancers. The assay identified small molecules that could restore growth in an engineered strain of yeast that undergoes inducible growth arrest in the presence of human telomerase. In a library of 678 compounds, the screening assay identified 8 such molecules. In a series of in vitro assays, three of the eight identified molecules were shown to inhibit human telomerase. Next steps could include testing the molecules in telomerase-positive cancer cell lines and screening a larger compound library in the yeast-based assay.
