Abstract:
:Transcriptional silencing of the DNA repair protein, O6-methylguanine-DNA methyltransferase (MGMT), occurs only in malignant or transformed cell lines, and such MGMT-deficient cells are hypersensitive to chemotherapeutic alkylating agents such as 1, 3-bis (2-chloroethyl)-1-nitrosourea (BCNU) and temozolomide. Previously we demonstrated in a panel of established cell lines that the lack of gene expression correlated with methylation
