Biomethylation of arsenic compounds appears to cause oxidative DNA damage and to increase their carcinogenicity, according to a new study published online November 23 in the Journal of the National Cancer Institute. Although biomethylation was once believed to detoxify inorganic arsenic, it is now thought to enhance its toxicity and potentially its carcinogenicity. To assess the role of arsenic biomethylation in oxidative DNA damage in mice, Michael P. Waalkes, Ph.D., of the National Cancer...
