WebApr 4, 2010 · S N1-type methylating agents generate O6 -methyl guanine (O 6-meG), which is a potently mutagenic, toxic, and recombinogenic DNA adduct. Recognition of O6-meG:T mismatches by mismatch repair (MMR) causes sister chromatid exchanges, which are representative of homologous recombination (HR) events. WebMar 1, 2001 · Temozolomide (TMZ) is a DNA-methylating agent that has recently been introduced into Phase II and III trials for the treatment of gliomas. TMZ produces O6-methylguanine in DNA, which mispairs with thymine during the …
