pubmed:abstractText |
Temozolomide (TMZ) is a methylating agent used in chemotherapy against glioblastoma. This work was designed to clarify details in repair pathways acting to remove DNA double-strand breaks (DSBs) induced by TMZ. Cultured mouse embryonic fibroblasts were used which were deficient in DSB repair genes such as homologous recombination repair-related genes X-ray repair cross-complementing group 2 (XRCC2)and radiation sensitive mutant54 (Rad54), non-homologous end joining repair-related gene DNAligase IV (Lig4). Cell sensitivity to drug treatments was assessed using colony forming assays. The most effective molecular target which was correlated with TMZ cell sensitivity was Lig4. In addition, it was found that small interference RNAs (siRNA) for Lig4 efficiently enhanced cell lethality induced by TMZ in human glioblastoma A172 cells. These findings suggest that down regulation of Lig4 might provide a useful tool for cell sensitization during TMZ chemotherapy.
