英文摘要Endosulfan is an extensively used organochlorine pesticide around the world, which was classified as a persistent organic pollutant (POP) in 2009. Although previous studies have documented the reproductive toxicity of endosulfan in a variety of organisms, little is known about the influence of endosulfan on the genome stability of germ cells and nonexposed progeny. Here we applied whole-genome sequencing to explore the germ cell mutagenicity of alpha-endosulfan in Caenorhabditis elegans (C. elegans). We found that, although low doses of alpha-endosulfan exhibited a minor effect on the reproductive capacity of C. elegans, chronic exposure to 1 mu M alpha-endosulfan significantly increased the mutation frequencies of nonexposed progeny. Further analysis of genome-wide mutation spectra demonstrated that alpha- endosulfan preferentially elicited A:T -> G:C substitutions and clustered mutations. By using worms deficient in DNA damage response genes, our results suggest the involvement of translesion synthesis polymerase ri in modulating alpha-endosulfan-induced mutations in germ cells. Together, these observations reveal the germ cell mutagenicity of alpha-endosulfan in C. elegans and the possible underlying mechanism. In addition, our findings implicate that germ cell mutagenicity might be a necessary consideration for the health risk assessment of environmental chemicals such as POPs.
