Abstract excerpt
The O(6)-methylguanine-DNA-methyltransferase (MGMT) inactivator O(6)-benzylguanine (O(6)-beG) is currently under clinical investigation as a potential tumour-sensitising agent. In clinical trials its use has been associated with increased myelotoxicity and a reduced maximum tolerated dose (MTD) for BCNU. Thus the concept of myeloprotection by gene therapy with an O(6)-beG-insensitive mutant of MGMT is soon to be...
