Abstract

The erythrocyte glutathione transferase (e-GST) is the most abundant GST isoenzyme in the red blood cells. This enzyme is able to inactivate numerous different toxic compounds, and many studies indicate its possible role as a biomarker in environmental toxicology since it is hyper-expressed in case of exposure to pollutants in humans as well as in animals. This chapter summarizes most of these studies, revealing also a peculiarity of this biomarker: many toxins induce hyper-expression of e-GST with consequent increased activity, but a few toxins are actually inhibitors of e-GST and cause a decrease in activity. Studies involving inhabitants, mammalians reared in polluted areas, miners, or other workers exposed to a variety of toxic chemicals, demonstrate that a simple, rapid, and inexpensive analysis of e-GST activity may provide an early alarm signal of contamination that can be verified with more traditional chemical analyses to characterize the nature of the contaminants.
