9269990-0	1997	The DNA repair protein O6-methylguanine-DNA methyltransferase protects against skin tumor formation induced by antineoplastic chloroethylnitrosourea.	1-(2-chloroethyl)-1-nitrosourea	126-148	O-6-methylguanine-DNA methyltransferase	Mus musculus	23-61	
9269990-2	1997	Because secondary tumor formation is a serious threat in chemotherapy with these drugs, we explored whether and to what extent the DNA repair protein DNA-O6-methylguanine:protein-L-cysteine S-methyltransferase (MGMT) protects against CNU-induced tumors.	1-(2-chloroethyl)-1-nitrosourea	234-237	O-6-methylguanine-DNA methyltransferase	Mus musculus	150-209	
9269990-2	1997	Because secondary tumor formation is a serious threat in chemotherapy with these drugs, we explored whether and to what extent the DNA repair protein DNA-O6-methylguanine:protein-L-cysteine S-methyltransferase (MGMT) protects against CNU-induced tumors.	1-(2-chloroethyl)-1-nitrosourea	234-237	O-6-methylguanine-DNA methyltransferase	Mus musculus	211-215	
9269990-6	1997	The results provide clear evidence that MGMT exerts protection against CNU-induced cancer.	1-(2-chloroethyl)-1-nitrosourea	71-74	O-6-methylguanine-DNA methyltransferase	Mus musculus	40-44	
9269990-7	1997	Our data also indicate that O6-chloroethylguanine, which is repaired by MGMT, is a main precarcinogenic CNU-induced DNA lesion.	1-(2-chloroethyl)-1-nitrosourea	104-107	O-6-methylguanine-DNA methyltransferase	Mus musculus	72-76
