WebSurprisingly, methylation resistance arose in three clones by reactivation of a previously silent O6-methylguanine-DNA methyltransferase gene. Five clones, including RajiF12, displayed the microsatellite instability and increased spontaneous mutation rates at the hypoxanthine-guanine phosphoribosyltransferase locus, consistent with deficiencies in … WebTo clarify the involvement of O'-methylguanine (O*-MeG) in mutagenesis, we isolated iV-methyl-iV'-nitro-iV-nitroso-guanidine (MNNG)-resistant cells, MR10-1 from HeLa S3 ... in the repair of the alkylated adducts which are related to cell killing and mutation, and also suggest that O6-MeG is involved in the induction of mutation.
