Abstract

Increasing research is illuminating the intricate roles of metal ions in neural development as well as neurological disorders, which may stem from misregulation or dysfunction of epigenetic modifiers. Lead (Pb), cadmium (Cd), aluminum (Al), and arsenic were chosen for critical review because they have become serious public health concerns due to globalization and industrialization. In this review, we will introduce various modes of action of metals and consider the role of two posttranslational modifications: histone acetylation and methylation and how each of them affects gene expression. We then summarize the findings from previous studies on the neurological outcomes and histone alterations in response to the metals on each of the previously described histone modifications mechanisms. Understanding metal-induced histone modifications changes could provide better insight on the mechanism through which neurotoxicity occurs, to propose and validate these modifications as possible biomarkers for early identification of neurological damage, and can help model targeted therapies for the diseases of the brain.
