英文摘要Due to the overload of pollutants from highly intensive anthropic activities, nitrite accumulates in offshore seawater and has been a long-lasting pollutant to the healthy aquaculture of the mollusk. In the present study, Ruditapes philippinarum was used as the target bivalve to receive nitrite exposure at environmental concentration for 1 and 7 days. Differentially expressed genes (DEGs) were detected and analyzed by a digital gene expression (DGE) approach to describe the toxicity of nitrite on the bivalve at the gene level. In the N1 group, 185 DEGs were generated and enriched in six Gene Ontology (GO) terms, including oxidoreductase activity, heme binding, tetrapyrrole binding, iron ion binding, metal binding and cation binding. The DEGs in the N1 group were also enriched in two Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, e.g., arachidonic acid metabolism and ovarian steroidogenesis. In the N7 group, 81 DEGs were generated without any GO enrichment but were enriched in five KEGG pathways, including protein processing in the endoplasmic reticulum, protein export, prion diseases, thyroid hormone synthesis and arachidonic acid metabolism. This suggested that nitrite exposure might cause adverse effects to the clams in several aspects, including oxidative damage, depressed immunity, and disorders in cell proliferation, hormone metabolism and tissue regeneration. Evaluation of oxidative stress indicated that nitrite exposure actually induced redox state imbalance by enhancing the contents of thiobarbituric acid reactive substances (TBARSs) and glutathione (GSH), and the activity of glutathione peroxidase (GSH-PX) but not superoxide dismutase (SOD). These results will provide valuable gene references for further study on the toxicology mechanism of bivalves under environmental nitrite stress.
