Glutathione levels and cytotoxicity of a thiol activated alkylating agent in human and mouse cells.

The effects of cellular GSH levels on the cytotoxicity of MNNG and mitomycin C were examined in normal and BSO treated mouse C3H10T1/2 cells. MNNG was less cytotoxic in the GSH depleted cells (less than 10% of normal) whereas the cytotoxicity of mitomycin C was not influenced by thiol status. This is compatible with the alkylating agent MNNG requiring… CONTINUE READING
