Zusammenfassung:Graphene oxide (GO) induces some dysregulated microRNAs (miRNAs), such as mir-247 , in Caenorhabditis elegans . We here further investigated the role and value of mir-247 in detecting GO toxicity in nematodes after prolonged exposure. In nematodes, mir-247 acted in neurons to regulate GO toxicity, and neuronal overexpression of mir-247 induced a susceptibility to GO toxicity. We detected the significant increase in mir-247 in wild-type nematodes exposed to GO at concentrations of more than 10 μg L −1 . Moreover, we found the GO toxicity in a transgenic strain overexpressing neuronal mir-247 after exposure to GO at concentrations of more than 10 μg L −1 . Therefore, our results imply the important potential of mir-247 in warning of the formation of GO toxicity in the range of μg L −1 in nematodes. Our results imply the important potential of mir-247 in warning the formation of GO toxicity in the range of μg L −1 in nematodes.
