| 英文摘要 | Japanese flounder (Paralichthys olivaceus) is an important economic fish species farmed in China and other countries. It is susceptible to infection by Edwardsiella tarda, a severe fish pathogen with a broad host range. In this study, we employed high-throughput deep sequencing technology to identify, in a global scale, flounder kidney microRNAs (miRNAs) induced by E. tarda at different stages of infection. Differentially expressed miRNAs (DEmiRNAs) and mRNAs (DEmRNAs) exhibiting significantly altered expression levels before and after E. tarda infection were examined. A total of 96 DEmiRNAs were identified, for which 2779 target genes were predicted. Eighty-seven miRNA-mRNA pairs, involving 29 DEmiRNAs and 86 DEmRNAs, showed negative correlations in their expression patterns. GO and KEGG enrichment analysis revealed that the putative target genes of the DEmiRNAs were associated with diverse biological processes, cellular components, and molecular functions. One of the DEmiRNAs, pol-miR-182-5p, was demonstrated to regulate sphingosine-1-phosphate receptor 1 (PoS1PR1) negatively in a manner that depended on the specific interaction between the seed sequence of polmiR-182-5p and the 3'-UTR of PoS1PR1. Overexpression of pol-miR-182-5p in flounder cells promoted apoptosis and inhibited cellular viability. Knockdown of PoS1PR1 in flounder enhanced E. tarda invasion and dissemination in fish tissues. These results provide new insights into miRNA-mediated anti-bacterial immunity in flounder. |
