BACKGROUND Diabetes is a major threat to public health in the United States and worldwide. Understanding the role of environmental chemicals in the development or progression of diabetes is an emerging issue in environmental health. OBJECTIVE We assessed the epidemiologic literature for evidence of associations between persistent organic pollutants (POPs)(More)
Oxidative damage to DNA is thought to play a significant role in mutagenesis, aging, and cancer. Sensitivity to oxidative DNA damage and DNA repair efficiency were examined using a series of human breast epithelial cell lines-MCF-10A, MCF-10AT, and MCF-10ATG3B-with progressively elevated Ras protein. Breast epithelial cells were treated with H2O2, in the(More)
The distribution of glutathione (GSH) and glutathione S-transferases (GSTs) in the adult rat brain is cell-type specific, but their cellular distribution in the developing central nervous system is unknown. In the present study, GSH distribution in the mouse nervous system was visualized by mercury orange histochemistry and class-specific GSTs were(More)
Glutathione and its related enzymes play a major role in the detoxification of toxic chemicals. In rat brain the pattern of distribution of reduced glutathione exhibits cellular heterogeneity, suggesting also the possibility of cellular differences in glutathione conjugating capacity. To understand the potential role of GSH in detoxification of(More)
