Aflatoxin B1-induced epigenetic alterations: An overview

Food Chem Toxicol. 2017 Nov;109(Pt 1):683-689. doi: 10.1016/j.fct.2017.06.034. Epub 2017 Jun 20.

Abstract

Aflatoxin B1 (AFB1) is widely distributed in nature, especially in a variety of food commodities. It is confirmed to be the most toxic of all the aflatoxins. The toxicity of AFB1 has been well investigated, and it may result in severe health problems including carcinogenesis, mutagenesis, growth retardation, and immune suppression. Epigenetic modifications including DNA methylation, histone modifications and regulation of non-coding RNA play an important role in AFB1-induced disease and carcinogenesis. To better understand the evidence for AFB1-induced epigenetic alterations and the potential mechanisms of the toxicity of AFB1, we conducted a review of published studies of AFB1-induced epigenetic alterations.

Keywords: Aflatoxin B1; DNA methylation; Epigenetics; Histone modifications; Non-coding RNA.
