Epigenetics in metal carcinogenesis: nickel, arsenic, chromium and cadmium
Abstract
Although carcinogenic metals have been known to disrupt a wide range of cellular processes the precise mechanism by which they exert their carcinogenic effects is not known. Over the last decade or two, studies in the field of metal carcinogenesis suggest that epigenetic mechanisms may play a role in metal-induced carcinogenesis. In this review we summarize the evidence demonstrating that exposure to carcinogenic metals such as nickel, arsenic, chromium, and cadmium can perturb
