| Research Abstract |
With the transformants of HeLa cells with cDNA library or the next-generation sequencer, we tried establishment of the general methodology to clarify the target molecules of the bioactive natural products that acts on the eukaryotes such as an animal cells. Using topoisomerase I inhibitor of camptothecin as a model compound, we succeeded in the establishment of the methods, which selects a camptothecin-resistant HeLa cell from the transformants of HeLa cells that over-expressed cDNA randomly, and analyzes the cDNA introduced from the camptothecin-resistant HeLa cell. We also succeeded in the preparation of spontaneous resistant HeLa cells against camptothecin for exhaustively analyzing genetic mutation using a next-generation sequencer.
