We previously reported fluctuating levels of many metabolites in the brain of mice administered methylmercury. In this study, addition of putrescine, a polyamine, to the medium was found to confer methylmercury resistance to C17.2 mouse neural stem cells with regard to metabolites increased by methylmercury in the mouse brain. However, putrescine had little effect on the cytotoxicity of heavy metals such as cadmium and inorganic mercury. These results suggest that putrescine may selectively alleviate methylmercury toxicity.
