The mismatch repair (MMR) system plays a major role in mediating the cytotoxicity and clastogenicity of agents generating O6-methylguanine in DNA. Loss of MMR has also been associated with tumor cell resistance to the cytotoxic effects of 6-thioguanine and cisplatin and with hypersensitivity to N-(2-chloroethyl)-N′-cyclohexyl-N-nitrosourea (CCNU). The aim of the present investigation was to elucidate the role played by the MMR system in the generation of chromosomal damage in cells exposed to 6… CONTINUE READING
