Influence of anoxia and respiratory deficiency on the genotoxicity of some direct-acting alkylating agents in yeast.

We have studied the influence of anoxia and respiratory deficiency (RD) in yeast on the cytotoxic and recombinogenic effects of 5 direct-acting alkylating agents, namely N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), methylnitrosourea (MNU), ethylnitrosourea (ENU), methyl methanesulphonate (MMS) and ethyl methanesulphonate (EMS). We found that the effects of… CONTINUE READING
