چکیده انگلیسی
MicroRNAs (miRNAs) are endogenous small non-coding RNAs that participate in the regulation of various biological processes. A series of microRNAs have been shown to be important regulators of both innate and adaptive immune responses, including RIG-I signaling pathway. In this study, we evaluated the regulation role of miR-210 in the RLRs signaling pathway of miiuy croaker. Upon poly(I:C) stimulation, the expression of miR-210 in both miiuy croaker spleen tissues and macrophages were significantly upregulated. By means of the dual luciferase reporter assay, a direct interaction between miR-210 and the 3-untranslated region (UTR) of Deubiquitinating enzyme A (DUBA) was confirmed, and we found that miR-210 could reduce the luciferase levels of wild-type DUBA 3â²UTR, whereas mutant-type led to a complete abrogation of the negative effect. Furthermore, the negative regulatory effects of pre-miR-210 on DUBA have been indicated in a dose- and time-dependent manners. As DUBA is an important regulator involved in the RLRs signaling pathway and could bind with and regulate TRAF3, we also examined the expression patterns of DUBA and TRAF3 in vivo and in vitro. We found that the expression of both DUBA and TRAF3 were significantly changed upon poly(I:C) stimulation in miiuy croaker. The expression patterns between miR-210 and DUBA showed a negative correlation, which indicated that miR-210 can target and downregulate the expression of DUBA. Overall, these results will enrich the knowledge of immune response related miRNAs in miiuy croaker, which will be useful for better understanding the complicated regulatory networks in fish species.
