Global Health Activities

Nutrients Involved in One-carbon Metabolism and the Methylation of Arsenic and DNA, Bangladesh: Chronic exposure to arsenic via contaminated drinking water is a worldwide problem associated with multiple adverse health effects. Metabolism of inorganic arsenic, which facilitates urinary excretion, relies on nutrient-dependent one-carbon metabolism and involves two methylation steps. Methylation of DNA is an epigenetic modification that plays important roles in the regulation of gene expression and may play a role in the underlying mechanism of arsenic-induced carcinogenesis. The overall purpose of this research is to investigate how several nutrients involved in one-carbon metabolism interact to influence arsenic and genomic DNA methylation.

B Vitamin Deficiencies, Arsenic, and Cognitive Function in Bangladeshi Adolescents, Bangladesh: The overall goal of this study is to test the hypothesis that suboptimal status of two nutrients, vitamin B12 and folate, and/or high plasma total homocysteine concentrations, either independently or in combination with arsenic exposure, are associated with impairments in cognitive function in 15-17 year-old Bangladeshi adolescents.
