MGMT (O-6-Methylguanine-DNA Methyltransferase): MGMT is a DNA repair enzyme that removes alkyl groups from the O6 position of guanine, preventing mutations and maintaining genomic stability. It plays a crucial role in protecting cells from mutagenic or carcinogenic effects of alkylating agents. MGMT's activity is a key factor in resistance to certain chemotherapy drugs, making it a focus of cancer treatment research, particularly in gliomas, where its expression can influence therapy outcomes....
