Gimeracil reduces the frequency of neo-positive clones. Additionally, it sensitized the cells in S-phase more than in G0/G1.
Gimeracil may enhance the efficacy of radiotherapy through the suppression of HR-mediated DNA repair pathways.
Gimeracil pretreatment significantly restrains the formation of radiation-induced foci of Rad51 and RPA, whereas it increased the number of foci of Nbs1, Mre11, Rad50, and FancD2.
Cell Viability Assay
| Cell Line: | DLD-1, HeLa, and LC-11 cell lines. |
| Concentration: | 1 mM. |
| Incubation Time: | 48 h. |
| Result: |
Inhibits the repair of irradiation-induced DNA double strand breaks.
Did not increase the c-H2AX foci residual at 24 h in unirradiated cells. |
Gimeracil (2.5-25 mg/kg, orally) may inhibit the rapid repair of X-ray-induced DNA damage in tumors.
