Chlorpyrifos exposure causes alternation in dopamine metabolism in PC12 cells.

abstract：:ABSTRACT Although copper is an essential metal and cadmium is an environmental pollutant, both are toxic when present in excess. Metallothionein and glutathione are two of the key components that participate in detoxification of copper and cadmium. In the present study the role of glutathione in resistance to copper a...
