1 It has been documented in cell lines that O(6)-methylguanine-DNA methyltransferase (MGMT) plays an important role in chloroethylnitrosourea (CENU) drug resistance. 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
2 It has been documented in cell lines that O(6)-methylguanine-DNA methyltransferase (MGMT) plays an important role in chloroethylnitrosourea (CENU) drug resistance. 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
3 It has been documented in cell lines that O(6)-methylguanine-DNA methyltransferase (MGMT) plays an important role in chloroethylnitrosourea (CENU) drug resistance. 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
4 It has been documented in cell lines that O(6)-methylguanine-DNA methyltransferase (MGMT) plays an important role in chloroethylnitrosourea (CENU) drug resistance. 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
5 The authors evaluated MGMT expression in 22 glioma specimens by using an immunofluorescence assay and compared the results with clinical response of the patients to CENU-based chemotherapy. 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
6 The Mer(-) patients (MGMT < 60,000 molecules/nucleus) appeared to have more chance of stable disease or response to CENU therapy than the Mer(+) patients (MGMT > 60,000 molecules/nucleus) (chi-square = 4.791, p = 0.0286). 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
7 Results from this study suggested that MGMT positivity is indicative of more aggressive disease that progresses more rapidly when exposed to CENU therapy. 1-(2-chloroethyl)-1-nitrosourea O-6-methylguanine-DNA methyltransferase Homo sapiens
