Outline of Final Research Achievements

Human topoisomerase inhibitors are effective against a broad spectrum of tumors. They induce DNA damage leading cell death by the inhibition of enzymatic topoisomerase reaction specifically.
Here, we studied the repair mechanism of topoisomerase-induced DNA damage in human cells. We found that ERCC1-XPF and RPA participates in DNA repair of the Top1-DNA damage complex and that FEN1 participates in repair of the 5'-phosphotyrosyl terminus of DNA single-strand breaks. Our data provided insights into the DNA repair mechanisms in tumor cells.
