Association between hemochromatosis genotype and lead exposure among elderly men: the normative aging study.
(2004)
Because body iron burden is inversely associated with lead absorption, genes associated with hemochromatosis may modify body lead burden. Our objective was to determine whether the C282Y and/or H63D hemochromatosis gene ...
Biomarkers of Lead Exposure and DNA Methylation within Retrotransposons
(National Institute of Environmental Health Sciences, 2010)
Background: DNA methylation is an epigenetic mark that regulates gene expression. Changes in DNA methylation within white blood cells may result from cumulative exposure to environmental metals such as lead. Bone lead, a ...
Iron Metabolism Genes, Low-Level Lead Exposure, and QT Interval
(National Institute of Environmental Health Sciences, 2008)
Background: Cumulative exposure to lead has been shown to be associated with depression of electrocardiographic conduction, such as QT interval (time from start of the Q wave to end of the T wave). Because iron can enhance ...
Lead Concentrations in Relation to Multiple Biomarkers of Cardiovascular Disease: The Normative Aging Study
(National Institute of Environmental Health Sciences, 2012)
Background: Lead exposure has been associated with cardiovascular disease (CVD) in animal and human studies. However, the mechanisms of action have not been fully elucidated. We therefore examined the relationship between ...
Modifying Effects of the HFE Polymorphisms on the Association Between Lead Burden and Cognitive Decline
(National Institute of Environmental Health Sciences, 2007)
Background: As iron and lead promote oxidative damage, and hemochromatosis (HFE) gene polymorphisms increase body iron burden, HFE variant alleles may modify the lead burden and cognitive decline relationship. Objective: ...
