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)
Differences in the cellular distribution of antioxidant defense mechanisms in heterogeneous tissue such as the nervous system are likely critical determinants of differential sensitivity to toxicants. Regional and cellular localization of reduced glutathione (GSH) in central and peripheral nervous tissue was determined from the pattern of fluorescence(More)
The International HapMap Project is a resource for researchers containing genotype, sequencing, and expression information for EBV-transformed lymphoblastoid cell lines derived from populations across the world. The expansion of the HapMap beyond the four initial populations of Phase 2, referred to as Phase 3, has increased the sample number and ethnic(More)
Cellular heterogeneity and structural complexity of the nervous system, coupled with regional and cellular differences in the metabolic capabilities of neurons, glia and other non-neuronal elements, may underlie the selective cellular involvement following exposure to neurotoxicants. Determination of the role of biotransformation of xenobiotics in neural(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)
The Cooperative Family Registry for Breast Cancer Studies (CFRBCS) is an international multisite cooperative consortium of investigators who collaborate to ascertain families at risk for breast cancer. Sufficient blood was collected from each individual participating in the CFRBCS to permit the isolation of lymphocytes, distribution into four aliquots, and(More)
We have examined the effects of prenatal protein malnutrition on interneuronally mediated inhibition and facilitation in the dentate gyrus of the rat using the paired-pulse technique. Field potentials were recorded in the dentate gyrus in response to paired stimuli delivered to the perforant path. The paired-pulse index (PPI) was used as a measure of the(More)
1346 20 JUNE 2014 • VOL 344 ISSUE 6190 sciencemag.org SCIENCE O ur understanding of genome biology, genomics, and disease, and even human history, has advanced tremendously with the completion of the Human Genome Project. Technological advances coupled with significant cost reductions in genomic research have yielded novel insights into disease etiology,(More)
The Human Genetic Cell Repository sponsored by the National Institute of General Medical Sciences (NIGMS) contains more than 11,000 cell lines and DNA samples collected from numerous individuals. All of these cell lines and DNA samples are categorized into several collections representing a variety of disease states, chromosomal abnormalities, heritable(More)
Conjugation with glutathione (GSH) is a mechanism of detoxification of acrylamide (ACR); hence, prior depletion of GSH might be expected to exacerbate ACR's neurotoxicity. GSH levels in female rats were reduced by ip administration of styrene oxide (SO; 250 mg/kg), diethylmaleate (DEM; 0.5 ml/kg), or 2-vinylpyridine (VP; 100 mg/kg) 1.5 or 2 hr prior to a(More)
