7934958-3	1994	In a test with three mutagens, one potent (ethylnitrosourea) and two weak (1,2-dimethylhydrazine and methyl methanesulphonate), ten weekly treatments induced ten times the frequency of Dlb-1 mutations induced by a single treatment in each case, a result that is consistent with perfect additivity.	1,2-Dimethylhydrazine	75-96	beta-1,4-N-acetyl-galactosaminyl transferase 2	Mus musculus	185-190	
2253241-4	1990	Chronic administration of 1,2-dimethylhydrazine (20 mg/kg/week s.c. for 10 weeks) induced Dlb-1 mutants, whereas administration of a single dose did not.	1,2-Dimethylhydrazine	26-47	beta-1,4-N-acetyl-galactosaminyl transferase 2	Mus musculus	90-95	
2253241-8	1990	The activities of 1,2-dimethylhydrazine, dimethylnitrosamine, and 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline in the Dlb-1 assay more accurately reflect their carcinogenic potential than do many in vitro bioassays.	1,2-Dimethylhydrazine	18-39	beta-1,4-N-acetyl-galactosaminyl transferase 2	Mus musculus	119-124
