摘要: Trichlorphon, a common organophosphorus pesticide (OPs), is widely used in aquaculture to prevent aquatic insects from infecting cultured objects as well as to control the excessive proliferation of plankton in water bodies. However, its repeated use time can contaminate water bodies and impart direct/indirect toxicity to beneficial aquatic species. However, the underlying mechanism regarding toxicity and cellular metabolism remains unclear. Understanding the mechanism would enable the standardized use and management of OPs and their use in the aquatic environment. Here, low concentration of trichlorphon (5 x 10-5 g/L) was used to construct a hepatopancreatic transcriptional library 30 d, 60 d and 90 d after exposure using RNA-Seq. We detected 649, 148, and 2949 DEGs in the hepatopancreas of E. sinensis for the Tri01 vs. Ctr01, Tri02 vs. Ctr02 and Tri03 vs. Ctr03 library, respectively. The results of KEGG pathway enrichment analysis showed that DEGs were mainly enriched in signal transduction, carbohydrate metabolism, transport and catabolism, endocrine system, and digestive system. Also, under trichlorfon stress, DEGs of E. sinensis were enriched in thyroid hormone signaling pathways, protein digestion and absorption, cancer pathways, etc. The significant DEGs were mainly related to metabolism and the apoptosis and autophagy pathways. This study lays a foundation for further revealing the effects of long-term trichlorfon stress on E. sinensis as well as the potential physiological toxicity. The relevant transcriptome data could provide a reference for the molecular toxicological evaluation of trichlorfon in aquaculture.
