Abstract excerpt
O(6)-methylguanine (O(6)MeG) is a highly critical DNA adduct induced by methylating carcinogens and anticancer drugs such as temozolomide, streptozotocine, procarbazine and dacarbazine. Induction of cell death by O(6)MeG lesions requires mismatch repair (MMR) and cell proliferation and is thought to be dependent on the formation of DNA double-strand breaks (DSBs) or, according to an alternative hypothesis, direct...
