Web1 dec. 2024 · In cases of epigenetic inhibition of the MGMT gene, translation and further synthesis of O-6-methylguanine-DNA-methyltransferase is limited. Due to the reduced quantity of this enzyme, the DNA repair, e.g., reversing of TMZ-induced modification O-6-methylguanine back to guanine is not performed, resulting in cellular apoptosis [29]. WebBACKGROUND AND AIMS: O(6)-Methylguanine-DNA methyltransferase (MGMT) removes methyl adducts from O(6)-guanine. Known as methylation tolerance, selection for mismatch repair (MMR)-deficient cells that are unable to initiate lethal processing of O(6)-methylguanine-induced mismatches in DNA is observed in vitro as a consequence of …
