| Outline of Final Research Achievements |
We investigated whether the balance between p53 and FEN1 decide the fate of cells. Inhibition of FEN1 induced celler senescence in p53 mutant T24 cells, but induced cell death in p53 wild type T24 cells. On the other hand, inhibition of FEN1 induced cell death in p53 wild type HCT116 cells, but did not induce celler senescence and cell death in p53 deficient HCT116 cells. These results suggest that relationship between p53 and FEN1 may decide the fate of cells.
