Abstract excerpt
This paper examines the mechanism by which 5-bromodeoxyuridine (BrdUrd) induces a high frequency of transient trifluorothymidine (F3TdR)-resistant variants in the TK6 human lymphoblast cell line (a TK +/- heterozygote). This phenomenon has previously been termed 'pseudomutation' (Liber et al., 1985). We now report that 5-azacytidine (5-AzaC), an inhibitor of DNA methylation, reverses BrdUrd-induced pseudomutation...
