TRIM25 inhibits spring viraemia of carp virus replication by positively regulating RIG-I signaling pathway in common carp (Cyprinus carpio L.). FISH & SHELLFISH IMMUNOLOGY 2022; 127:306-317. [PMID: 35753558 DOI: 10.1016/j.fsi.2022.06.033] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 05/13/2022] [Accepted: 06/20/2022] [Indexed: 06/15/2023]
Abstract
Common carp (Cyprinus carpio L.) is one of the most widely cultivated fish in China. Spring viraemia of carp virus (SVCV) is a highly pathogenic virus and has often caused excessive losses in carp pond fisheries. Innate immune play important roles against virus infection. To better understand the immune response of common carp against SVCV infection, transcriptome analysis was performed using the Illumina Novaseq 6000 platform. It was showed that a total of 3953 differentially expressed unigenes were identified, and the RLR signaling pathway were significantly enriched after SVCV infection. Subsequently, the role of RLR signaling pathway in SVCV infection was studied. The results showed that common carp RIG-I (CcRIG-I) and TRIM25 (CcTRIM25) significantly decreased the replication of SVCV by inducing the phosphorylation of TBK1, IRF3 and p65 and the expression of ifn-1, viperin, isg15 and mx. Further studies illustrated that CcTRIM25 could positive regulate CcRIG-I mediated downstream signaling pathway. Finally, the mechanism of CcTRIM25 promoting CcRIG-I-mediated signaling was investigated. CcTRIM25 could interact with the caspase activation and recruitment domain (CARD) of CcRIG-I and promoted K63-linked polyubiquitination of CcRIG-I. Altogether, the study revealed a mechanism of CcTRIM25 regulating CcRIG-I mediated immune response in SVCV infection.

Molecular identification and function characterization of four alternative splice variants of trim25 in Japanese flounder (Paralichthys olivaceus). FISH & SHELLFISH IMMUNOLOGY 2022; 120:142-154. [PMID: 34808358 DOI: 10.1016/j.fsi.2021.11.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 11/13/2021] [Accepted: 11/16/2021] [Indexed: 06/13/2023]
Abstract
Trim25 is a member of Tripartite Motif (TRIM) family. Previous studies report that trim25 modulates antiviral activity by activating RIG-I. In this study we explored the four alternative splicing (AS) variants X1-X4 of Japanese flounder trim25. The sequences of the AS variants were highly conserved. Expression levels of trim25 X1-X4 were increased after 12 h of poly I:C treatment in vitro. In vivo expression of X2-X4 in liver, kidney (except X2) and blood was significantly up-regulated in early stages of poly I:C treatment. Subcellular localization analysis showed that Trim25 X1-X4 were distributed in different cellular organelles. The recombinant vector pcDNA3.1-Trim25 X1-X4 were successfully overexpressed in Flounder cells and the samples were collected. Expression patterns of RIG-I pathway genes dhx58, traf6, traf2, nfkbia and il-8 were explored in vitro and in vivo after poly I:C treatment, as well as overexpressed samples. The findings of this study imply that AS variants of trim25 confer antiviral activity in Japanese flounder by modulating innate immune response.

Abstract
We isolated and characterised a cDNA encoding the aspartic protease cathepsin E (CTSE) in Korean rose bitterling, Rhodeus uyekii. The full-length Rhodeus uyekii CTSE (RuCTSE) cDNA (1396 bp) contains an open reading frame of 1218 bp, encoding 405 amino acids. Alignment of multiple CTSE protein sequences revealed that two of the aspartyl protease active site residues and a disulphide bond were well-conserved among the other CTSE sequences. Phylogenetic analysis revealed that RuCTSE is most closely related to freshwater fish cathepsin E. RuCTSE is widely expressed in the liver, spleen, ovary, testis, brain, eye, intestine, muscle, fin, stomach, and kidney. This first report of teleost CTSE will provide important information related to the identification of other cathepsin E genes in various fish species and will serve as a useful molecular tool to help clarify biological activities in other teleosts.

Abstract
RIG-I-like receptors (RLRs) play important roles in response to virus infection by regulating host innate immune signaling pathways. Meanwhile, the RLR signaling pathway is also tightly regulated by host and virus to achieve the immune homeostasis between antiviral responses and virus survival. Here, we found that zebrafish TRIM25 (zbTRIM25) functioned as a positive regulator of RLR signaling pathway during red spotted grouper nervous necrosis virus (RGNNV) infection. Post-RGNNV infection, zbTRIM25 expression was obviously inhibited and ectopic expression of zbTRIM25 led to enhanced expression of RLR signaling pathway-related genes. Overexpression and knockdown analysis revealed that zbTRIM25 promoted zebrafish RIG-I (zbRIG-I)-mediated IFN signaling and inhibited RGNNV replication. Mechanistically, zbTRIM25 bound to zbRIG-I; in particular, the SPRY domain of zbTRIM25 interacted with the tandem caspase activation and recruitment domains (2CARD) and repressor domain (RD) regions of zbRIG-I. zbTRIM25 promoted the K63 polyubiquitination of 2CARD and RD regions of zbRIG-I. Furthermore, zbTRIM25-mediated zbRIG-I activation of IFN production was enhanced by K63-linked ubiquitin, indicating that zbTRIM25-mediated zbRIG-I polyubiquitination was essential for RIG-I-triggered IFN induction. In conclusion, these findings reveal a novel mechanism that zbTRIM25 positively regulates the innate immune response by targeting and promoting the K63-linked polyubiquitination of zbRIG-I.

Abstract
In this study, we identified and characterized a tripartite motif containing 25 (TRIM25) gene homologue, LcTRIM25, from large yellow croaker (Larimichthys crocea). Two isoforms of LcTRIM25, which were generated via alternative splicing, were identified via a molecular analysis of cDNA clones. The long isoform of LcTRIM25 (termed as LcTRIM25-L) contained the full open reading frame of the gene, encoded a protein of 698 amino acid residues, and possessed 11 exons. The short isoform of LcTRIM25 (termed as LcTRIM25-S) contained 9 exons and encoded a protein of 665 amino acid residues. The two LcTRIM25 isoforms contained a conserved Really Interesting New Gene (RING) domain, a B-box2 domain, a Coiled-coil domain (CCD), and variable C-terminal PRY/SPRY domains. Phylogenetic analysis showed that the two LcTRIM25 isoforms of the large yellow croaker was clustered together with their counterparts from other teleost fish. The Real-time PCR analysis showed that the LcTRIM25-L and LcTRIM25-S isoforms were both ubiquitously expressed in nine examined tissues in the large yellow croaker, with predominant expressions in the liver. The expression levels of the two isoforms of LcTRIM25 were rapidly and significantly upregulated in vivo after poly (I:C) stimulation in peripheral blood, head kidney, spleen and liver. Moreover, LcTRIM25-L and LcTRIM25-S showed differential expression post poly(I:C) stimulation. LcTRIM25 may have a dual role in innate immunity via alternative gene splicing. These results indicated that LcTRIM25 is likely to be involved in antiviral immune responses.

Abstract
The tripartite motif-containing (TRIM) proteins are involved in a wide range of cellular processes, and the role of TRIM1 in immunity has been explored. However, fundamental studies on fish TRIM1 are lacking. In this study, we cloned and characterized TRIM1 cDNA from the Korean rose bitterling, Rhodeus uyekii (RuTRIM1). Two RuTRIM1 isoforms (RuTRIM1-X1 and RuTRIM1-X2) were identified. The coding sequence (CDS) of RuTRIM1-X1 comprised 2157 bp encoding a 718-aa protein, and the CDS of RuTRIM1-X2 comprised 1929 bp encoding a 642-aa protein. Both RuTRIM1 isoforms contained a RING finger domain, B-box 1, B-box 2, coiled-coil domain, COS box, FN3 motif, and PRY/SPRY domain. The deduced RuTRIM1-X1 and RuTRIM1-X2 proteins had high amino acid identity (76.27-98.89%) with orthologs from various other species, and a phylogenetic tree was constructed. RuTRIM1-X1 and RuTRIM1-X2 mRNA were expressed in all tissues examined, with the highest expression levels detected in the hepatopancreas. During early development, RuTRIM1-X1 and RuTRIM1-X2 mRNA levels changed differently from the gastrula period to the first feeding stage. An in vivo ubiquitination assay showed that RuTRIM1 exhibited RING-dependent E3 ubiquitin ligase activity, mainly by comparing RuTRIM1-X2 to RuTRIM1-X1. The subcellular localization of the two RuTRIM1 protein isoforms was characterized, revealing that they formed aggregates in cytoplasmic bodies in Raw264.7 cells. Interferon-γ/lipopolysaccharide-induced nuclear factor-κB signaling was negatively regulated by RuTRIM1-X1 and RuTRIM1-X2, and the negative effect was reversed in RING deletion mutants. To our knowledge, this is the first study to characterize fish TRIM1, which may play a role in the inflammatory response.

Abstract
In mammals, type I interferons (IFNs) are primarily regulated by transcription factors of the IFN regulatory (IRF) family. Interferon regulatory factor 5 (IRF-5) plays pivotal roles in antiviral and inflammatory responses. In the present study, we found that zebrafish (Danio rerio) IRF5 is a key player in the regulation of the expression of type I IFN and its antiviral immune response. IRF5 was upregulated in zebrafish embryonic fibroblast cells (ZF4) when challenged with grass carp reovirus (GCRV). Moreover, the expression profiles of Mx, IFN, Viperin, and IRF7, but not IRF3, were upregulated by overexpression of IRF5 in Epithelioma papulosum cyprinid cells (EPCs). Luciferase assays revealed that the activation of the IFNϕ1 promoter was stimulated by overexpression of IRF5 and IRF5-△IAD (IRF5 lacking the IRF-associated domain), respectively. However, overexpression of IRF5 or IRF5-△IAD inhibited the activity of the IFNϕ3 promoter. IRF5-△DBD (lacking the DNA-binding domain) had no influence in the activation of the IFNϕ1 and IFNϕ3 promoters. Furthermore, the determination of the cytopathic effect (CPE) numbers and viral titers revealed that the viral concentration was reduced by ectopic expression of IRF5 in EPC cells. Ectopic expression of IRF5 in EPC cells could protect cells from GCRV and significantly inhibited GCRV virus replication. These data indicated that IRF5 could limit viral replication through an IFN-dependent pathway.

Abstract
Tripartite motif-containing 25 (TRIM25) has been demonstrated to exert crucial roles in the regulation of innate immune signaling. However, the roles of fish TRIM25 in antiviral immune response still remained uncertain. Here, a novel fish TRIM25 gene from orange spotted grouper (EcTRIM25) was cloned and its roles in grouper virus infection were elucidated. EcTRIM25 encoded a 734-aa protein which shared 68% identity to large yellow croaker (Larimichthys crocea). Amino acid alignment showed that EcTRIM25 contained three conserved domains, including a RING-finger domain, a B box/coiled-coil domain and a SPRY domain. In healthy grouper, the transcript of EcTRIM25 was predominantly detected in skin, spleen and intestine. After stimulation with Singapore grouper iridovirus (SGIV) or poly I:C, the relative expression of EcTRIM25 in grouper spleen was significantly increased at the early stage of injection. Subcellular localization analysis showed that EcTRIM25 distributed throughout the cytoplasm in grouper cells. Notably, the deletion RING domain affected its accurate localization and displayed microtubule like structures or bright aggregates in GS cells. After incubation with SGIV or red spotted grouper nervous necrosis virus (RGNNV), overexpression of full length of EcTRIM25 in vitro significantly decreased the viral gene transcription of SGIV and RGNNV. Consistently, the deletion of RING domain obviously affected the inhibitory effect of EcTRIM25. Furthermore, overexpression of EcTRIM25 significantly increased the expression level of interferon related signaling molecules, including interferon regulatory factor (IRF) 3, interferon-induced 35-kDa protein (IFP35), MXI, IRF7 and myeloid differentiation factor 88 (MyD88), suggesting that the positive regulation of interferon immune response by EcTRIM25 might affected RGNNV replication directly. Meanwhile, the expression levels of pro-inflammation cytokines were differently regulated by the ectopic expression of EcTRIM25. We proposed that the regulation of IRF7, MyD88 and pro-inflammation cytokines might contribute more important roles in SGIV infection. In addition, the RING domain of EcTRIM25 also played critical roles in the regulation of interferon immune and inflammation response. Together, our results will provide new evidences that the RING domain was essential for the antiviral action of fish TRIM25 against iridovirus and nodavirus infection.

Abstract
The potential impact of natural and synthetic estrogens on aquatic ecosystems has become a subject of great interest in recent years. One synthetic estrogen, 17-alpha-ethinylestradiol (EE2), is present in municipal sewage discharges and causes gonad alterations in various fish species. To understand the possible damage caused by EE2, male Rhodeus uyekii were exposed to 100 ng/L EE2 for 7 days. RNA-Seq was performed to assess the effects of EE2 on gene expression in hepatic and skin tissues. The analysis revealed that EE2 induced the expression of various genes, including sex hormone genes, anti-Mullerian hormone, vitellogenin, and estrogen receptor alpha; cancer genes, breast cancer anti-estrogen resistance protein 3, caveolin 2, and Smad2; and apoptotic genes, p53, Bcl-2, TNF-α, and WDR36. These results suggest that the synthetic estrogen EE2 disturbs the endocrine system and regulates both carcinogenic and apoptotic gene expressions in R. uyekii.
