▎ 摘　　要

Long noncoding RNAs (lncRNAs), which are defined as noncoding RNAs having at least 200 nucleotides, can potentially regulate various biological processes. However, the roles of IncRNAs in regulating cellular response to engineered nanomaterials (ENMs) are still unclear. Using Hiseq 2000 sequencing technique, we performed a genome-wide screen to identify IncRNAs involved in the control of toxicity of graphene oxide (GO) using in vivo Caenorhabditis elegans assay system. HiSeq 2000 sequencing, followed by quantitative analysis, identified only 34 dysregulated IncRNAs in GO exposed nematodes. Bioinformatics analysis implies the biological processes and signaling pathways mediated by candidate IncRNAs involved in the control of GO toxicity. A IncRNAs-miRNAs network possibly involved in the control of GO toxicity was further raised. Moreover, we identified the shared lncRNAs based on the molecular regulation basis for chemical surface modifications and/or genetic mutations in reducing GO toxicity. We further provide direct evidence that these shared lncRNAs, linc-37 and linc-14, were involved in the control of chemical surface modifications and genetic mutations in reducing GO toxicity. linc-37 binding to transcriptional factor FOXO/DAF-16 might be important for the control of GO toxicity. Our whole-genome identification and functional analysis of IncRNAs highlights the important roles of IncRNAs based molecular mechanisms for cellular responses to ENMs in organisms.
