Title: | The Impact of Air Pollution on Our Epigenome: How Far Is the Evidence? (A Systematic Review) | Authors: | ALFANO, Rossella Herceg, Zdenko NAWROT, Tim Chadeau-Hyam, Marc Ghantous, Akram PLUSQUIN, Michelle |
Issue Date: | 2018 | Publisher: | SPRINGERNATURE | Source: | Current Environmental Health Reports, 5(4), p. 544-578 | Abstract: | PURPOSE OF REVIEW: This systematic review evaluated existing evidence linking air pollution exposure in humans to major epigenetic mechanisms: DNA methylation, microRNAs, long noncoding RNAs, and chromatin regulation. RECENT FINDINGS: Eighty-two manuscripts were eligible, most of which were observational (85%), conducted in adults (66%) and based on DNA methylation (79%). Most observational studies, except panel, demonstrated modest effects of air pollution on the methylome. Panel and experimental studies revealed a relatively large number of significant methylome alterations, though based on smaller sample sizes. Particulate matter levels were positively associated in several studies with global or LINE-1 hypomethylation, a hallmark of several diseases, and with decondensed chromatin structure. Several air pollution species altered the DNA methylation clock, inducing accelerated biological aging. The causal nature of identified associations is not clear, however, especially that most originate from countries with low air pollution levels. Existing evidence, gaps, and perspectives are highlighted herein. | Keywords: | Air pollution; Epigenetics; DNA methylation; MicroRNAs; Noncoding RNA; Chromatin | Document URI: | http://hdl.handle.net/1942/28285 | e-ISSN: | 2196-5412 | DOI: | 10.1007/s40572-018-0218-8 | ISI #: | WOS:000544901500013 | Category: | A1 | Type: | Journal Contribution |
