Research Abstract |
This study aims to design a telomere-directed cancer therapy. As main results, we found that G-quadruplex ligands induce DNA damage and transcriptional aberration and inhibit growth of glioma stem cells. We also found that self-assembly of tankyrase, a positive regulator of telomere elongation represses its function. Furthermore, we found that cancer cells that exhibit low expression of telomere-related factors, WRN and POT1, are sensitive to anti-microtubule drugs. These results would be applicable to development of new cancer chemotherapy
