Influence of glutathione S-transferase polymorphisms on cognitive functioning effects induced by p,p'-DDT among preschoolers

5 pages, 4 tables.-- PMID: 19057715 [PubMed].-- PMCID: PMC2592282.-- Printed version published Nov 2008.Background Early-life exposure to p,p′-DDT [2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane] is associated with a decrease in cognitive skills among preschoolers at 4 years of age. We hypothesized that genetic variability in glutathione S-transferase (GST) genes (GSTP1, GSTM1, and GSTT1) could influence the effects of prenatal exposure to p,p′-DDT.Methods We used data from 326 children assessed in a prospective population-based birth cohort at the age of 4 years. In that study, the McCarthy Scales of Children’s Abilities were administrated by psychologists, organochlorine compounds were measured in cord serum, and genotyping was conducted for the coding variant Ile105Val from GSTP1 and for null alleles from GSTM1 and GSTT1. We used linear regression models to measure the association between organochlorines and neurodevelopmental scores by GST polymorphisms.Results p,p′-DDT cord serum concentration was inversely associated with general cognitive, memory, quantitative, and verbal skills, as well as executive function and working memory, in children who had any GSTP1 Val-105 allele. GSTP1 polymorphisms and prenatal p,p′-DDT exposure showed a statistically significant interaction for general cognitive skills (p = 0.05), quantitative skills (p = 0.02), executive function (p = 0.01), and working memory (p = 0.02). There were no significant associations between p,p′-DDT and cognitive functioning at 4 years of age according to GSTM1 and GSTT1 polymorphisms.Conclusions Results indicate that children with GSTP1 Val-105 allele were at higher risk of the adverse cognitive functioning effects of prenatal p,p′-DDT exposure.This study was funded by grants from the Spanish Ministry of Health (FIS-PI041436, FIS-PI041705, FIS-PI051187), Instituto de Salud Carlos III (Red INMA G03/176 and CB06/02/0041), and Ciber en Epidemiología y Salud Pública, the Generalitat de Catalunya-CIRIT (Consejo Interdepartmental de Investigación e Innovación de Cataluña) (1999SGR 00241), and Genome Spain.Peer reviewe

You Are Now in the Middle of a N.E. Thing Co. Landscape : Works by Ian and Ingrid Baxter, 1965-1971

Discussing the view of conceptual art as existing outside major centres, Wood presents the work of the N.E. Thing Co. (NETCO) as "not derivative but distributive, not subsidiary but on-line." Shaw examines NETCO's landscape works, encompassing "nature, mapping, environmental and communication systems, the body, and the suburban and the urban." In individual texts (some reprinted), nine essayists deal with the relation of business and art, NETCO's media use, and the ethos of the group's activity. 42 bibl. ref
