Abstract
Early life exposure to inorganic arsenic is associated with a wide range of malignant and chronic disease outcomes in humans. Prenatal arsenic exposure may give rise to adverse effects on child health and development as arsenic readily passes through the placenta in human beings. The impact of maternal arsenic exposure on fetal gene expression was conducted in pregnant women living in Southern Thailand. Arsenic exposed newborns had significantly higher levels of arsenic in cord blood, and a set of genes associated with numerous biological pathways, including cell signaling, apoptosis, inflammatory and stress response. A slight increase in promoter methylation of p53 in cord blood lymphocytes which correlated with arsenic accumulation in nails was observed in these exposed newborns. A follow-up study on these exposed children showed a significant increase in oxidative DNA damage, measured as 8-hydroxydeoxyguanosine (8-OHdG) in saliva. In addition, levels of urinary 8-OHdG excretion and salivary hOGG1 expression were significantly decreased in exposed children suggesting a defect in repair of 8-OHdG in arsenic-exposed children. Our study indicates that prenatal arsenic and continued exposure through early childhood can trigger various genetic and epigenetic alterations that may lead to disease development later in life.
