Abstract excerpt
Dose fractionation of a direct-acting chemical carcinogen, the alkylating agent N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), was studied for its concurrent effects on survival, DNA damage and repair, ouabain resistance (Ouar) mutations and neoplastic transformation, in the mouse embryo cell line BALB/3T3 C1A31-1-1. MNNG doses of 0.5, 1 and 2 micrograms/ml were added to the cells either as a single exposure or in...
