摘要 | In this study, we examined the function of a Japanese flounder (Paralichthys olivaceus) microRNA (miRNA), polmiR-363-3p. We found that pol-miR-363-3p targets an ubiquitin-specific protease (USP), USP32. USP is a family of deubiquitinating enzymes essential to the functioning of the ubiquitin proteasome system. In mammals, USP32 is known to be associated with cancer and immunity. In fish, the function of USP32 is unknown. We found that flounder USP32 (PoUSP32) expression was detected in the major tissues of flounder, particularly intestine. In vitro and in vivo studies showed that pol-miR-363-3p directly regulated PoUSP32 in a negative manner by interaction with the 3 ' UTR of PoUSP32. Overexpression of pol-miR-363-3p or interference with PoUSP32 expression in flounder cells significantly blocked Streptococcus iniae infection. Consistently, in vivo knockdown of pol-miR-363-3p or overexpression of PoUSP32 enhanced dissemination of S. iniae in flounder tissues, whereas in vivo knockdown of PoUSP32 inhibited S. iniae dissemination. In addition, pol-miR-363-3p knockdown also significantly promoted the tissue dissemination of the viral pathogen megalocytivirus, which, as well as S. iniae, regulated pol-miR-363-3p expression. Together these results revealed an important role of pol-miR-363-3p in flounder immune defense against bacterial and viral infection. |
