Our study takes advantage of an extensively characterized
population in Mae Sot, Thailand with a wide range of urinary Cd
levels to validate DNA methylation markers of Cd exposure in a
human population. DNMT3B, MGMT, LINE-1 and MT2A were chosen
based on in vitro and in vivo evidence of their association with Cd.
This is the first study to be able to look at such exposure ranges
within the context of DNA methylation in a population-based study.
Studies such as these are a logical first step to identifying the
mechanisms of Cd toxicity and may identify useful biomarkers
