Abstract
The family of TRIM proteins with E3 ubiquitin ligase activity served important roles in the regulation of innate immune processes, in particular antiviral and proinflammatory cytokine responses. In this study, a novel TRIM37 homolog was identified from Penaeus monodon (named PmTRIM37). The PmTRIM37 protein contained three conserved domains (one RING finger domain, a B-box, and one Coiled-coil region) at its N-terminal and one Meprin and MATH domain at its C-terminal. The MATH domain was the characteristic of TRIM37 family. PmTRIM37 has relatively high expression in immune-related tissues such as hepatopancreas, gills, lymphoid organs and hemocytes. The expression levels of PmTRIM37 in hepatopancreas and lymphoid organs were significantly up-regulated after white spot syndrome virus (WSSV) infection. Knock down of PmTRIM37 promoted WSSV replication and VP28 expression, suggesting that PmTRIM37 played a negative role in WSSV infection. Further studies revealed that PmTRIM37 positively regulated the NF-κB pathway and Antimicrobial peptides (AMP) expression during WSSV infection. These findings indicated that PmTRIM37 might restrict WSSV replication by positively regulating NF-κB pathway during WSSV infection in P. monodon.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 142:104671.

Abstract
In mammals, the tripartite motif (TRIM) proteins have been identified as critical factors involved in various cellular processes, including antiviral immunity. In teleost fish, a subfamily of fish-specific TRIM (finTRIM, FTR) has emerged in genus- or species-specific duplication. In this study, a finTRIM gene, called ftr33, was identified in zebrafish (Danio rerio), and phylogenic analysis revealed that FTR33 is closely related with zebrafish FTR14. The FTR33 protein contains all conservative domains reported in other finTRIMs. The ftr33 has a constitutive expression in embryos and in tissues/organs of adult fish, and its expression can be induced following spring viremia of carp virus (SVCV) infection and interferon (IFN) stimulation. The overexpression of FTR33 significantly downregulated the expression of type I IFNs and IFN-stimulated genes (ISGs) both in vitro and in vivo, respectively, leading to the increased replication of SVCV. It was also found that FTR33 interacted with melanoma differentiation associated gene 5 (MDA5) or mitochondrial anti-viral signaling protein (MAVS) to weaken the promoter activity of type I IFN. It is thus concluded that the FTR33, as an ISG, in zebrafish can negatively regulate IFN-mediated antiviral response.

Genes (Basel) 2023; 14:genes14030667. [PMID: 36980939 PMCID: PMC10048487 DOI: 10.3390/genes14030667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 02/03/2023] [Accepted: 03/02/2023] [Indexed: 03/30/2023] Open
Abstract
Tripartite motifs (TRIM) is a large family of E3 ubiquitin ligases that play an important role in ubiquitylation. TRIM proteins regulate a wide range of biological processes from cellular response to viral infection and are implicated in various pathologies, from Mendelian disease to cancer. Although the TRIM family has been identified and characterized in tetrapods, but the knowledge about common carp and other teleost species is limited. The genes and proteins in the TRIM family of common carp were analyzed for evolutionary relationships, characterization, and functional annotation. Phylogenetic analysis was used to elucidate the evolutionary relationship of TRIM protein among teleost and higher vertebrate species. The results show that the TRIM orthologs of highly distant vertebrates have conserved sequences and domain architectures. The pairwise distance was calculated among teleost species of TRIMs, and the result exhibits very few mismatches at aligned position thus, indicating that the members are not distant from each other. Furthermore, TRIM family of common carp clustered into six groups on the basis of phylogenetic analysis. Additionally, the analysis revealed conserved motifs and functional domains in the subfamily members. The difference in functional domains and motifs is attributed to the evolution of these groups from different ancestors, thus validating the accuracy of clusters in the phylogenetic tree. However, the intron-exon organization is not precisely similar, which suggests duplication of genes and complex alternative splicing. The percentage of secondary structural elements is comparable for members of the same group, but the tertiary conformation is varied and dominated by coiled-coil segments required for catalytic activity. Gene ontology analysis revealed that these proteins are mainly associated with the catalytic activity of ubiquitination, immune system, zinc ion binding, positive regulation of transcription, ligase activity, and cell cycle regulation. Moreover, the biological pathway analyses identified four KEGG and 22 Reactome pathways. The predicted pathways correspond to functional domains, and gene ontology which proposes that proteins with similar structures might perform the same functions.

Dual-Targeting Polymer Nanoparticles Efficiently Deliver DNA Vaccine and Induce Robust Prophylactic Immunity against Spring Viremia of Carp Virus Infection. Microbiol Spectr 2022; 10:e0308522.

Abstract
Spring viremia of carp virus (SVCV) is highly contagious and lethal to most cyprinid fish, causing serious economic losses to the carp aquaculture industry. Although DNA vaccines can generate long-term humoral and cellular immune responses, which provide protective immunity against SVCV, the major drawback of DNA vaccines is their low immunogenicity in clinical tests. Here, we construct a dual-targeted polymer DNA vaccine delivery platform (MCS-PCHG) by using mannosylated chitosan to encapsulate the poly(d,l-lactide-co-glycolide)-loaded DNA vaccine containing the heavy-chain CH3 region (CH3) of common carp IgM and the antigenic domain (G131c). The developed nanovaccine delivery platform showed good biocompatibility in vivo and in vitro. With the modification of the mannose moiety and the modification of CH3, the constructed MCS-PCHG could efficiently activate the maturation of antigen-presenting cells. Moreover, we observe significantly high level of immune-related genes expression, serum antigen-specific IgM, SVCV-neutralizing antibody titers in fish vaccinated with MCS-PCHG. Next, the protective efficacy of MCS-PCHG was further evaluated by challenge test. The highest survival rate (ca. 84%) was observed in fish vaccinated with MCS-PCHG after challenging with SVCV. This study presents a novel design for smart, dual-targeted polymer nanoparticles, which are inherently biocompatible, promising for targeted vaccine delivery. IMPORTANCE Spring viremia of carp virus (SVCV) affects global cyprinid fish farming industry, with no available commercial vaccine. Herein, we developed a dual-targeting polymer nanovaccine (MCS-PCHG) by using mannose and common carp IgM heavy chain CH3 region (CH3) as antigen presenting cell (APCs) recognition moiety, attaining the effective delivery of antigen. This dual-targeting polymer vaccine can efficiently activate the APCs, and further induce robust and durable adaptive immune response with good protection against SVCV infection. Our study provides valuable theoretical basis for developing efficient vaccine against infectious diseases in aquaculture.

Abstract
Abstract
Tripartite motif (TRIM) family proteins have come forth as important modulators of innate signaling dependent on of E3 ligase activity. Recently, several human TRIM proteins have been identified as unorthodox RNA-binding proteins by RNA interactome analyses; however, their targets and functions remain largely unknown. FTRCA1 is a crucian carp (Carassius auratus)–specific finTRIM (fish novel TRIM) member and negatively regulates the IFN antiviral response by targeting two retinoic acid–inducible gene-I (RIG-I)–like receptor (RLR) pathway molecules, that is, TANK-binding kinase 1 (TBK1) and IFN regulatory factor 7 (IRF7). In this study, we identify FTRCA1 as an RNA-binding E3 ligase and characterize the contribution of its RNA-binding activity and E3 ligase activity to fish IFN response. Besides targeting TBK1 and IRF7, FTRCA1 downregulates fish IFN response also by targeting stimulator of IFN response cGAMP interactor 1 (STING1). E3 ligase activity is required for full inhibition on the TBK1- and IRF7-mediated IFN response, but partial inhibition on the STING1-mediated IFN response. However, FTRCA1 has a general binding potential to mRNAs in vitro, it selectively binds STING1 and IRF7 mRNAs in vivo to attenuate mRNA levels, and it directly interacts with TBK1 protein to target protein degradation for downregulating the IFN response. Our results present an interesting example of a fish species–specific finTRIM protein that has acquired RNA-binding activity and E3 ligase activity to fine-tune fish IFN response.

Abstract
Cyprinid herpesvirus 2 (CyHV-2) causes herpesviral hematopoietic necrosis (HVHN) disease outbreaks in farmed Cyprinid fish, which leads to serious economic losses worldwide. Although oral vaccination is considered the most suitable strategy for preventing infectious diseases in farmed fish, so far there is no commercial oral vaccine available for controlling HVNN in gibel carp (C. auratus gibelio). In the present study, we developed for the first time an oral vaccine against CyHV-2 by using yeast cell surface display technology and then investigated the effect of this vaccine in gibel carp. Furthermore, the protective efficacy was evaluated by comparing the immune response of a single vaccination with that of a booster vaccination (booster-vaccinated once 2 weeks after the initial vaccination). Critically, the activities of immune-related enzymes and genes expression in vaccine group, especially in the booster vaccine group, were higher than those in the control group. Moreover, strong innate and adaptive immune responses could be elicited in both mucosal and systemic tissues after receipt of the oral yeast vaccine. To further understand the protective efficacy of this vaccine in gibel carp, we successfully developed the challenge model with CyHV-2. Our results showed the relative percent survival was 66.7% in the booster vaccine group, indicating this oral yeast vaccine is a promising vaccine for controlling CyHV-2 disease in gibel carp aquaculture.

Abstract
Tripartite motif (TRIM) proteins play a regulatory function in cancer, cell apoptosis and innate immunity. To understand the role of TRIM39 in Nile tilapia (Oreochromis niloticus), TRIM39 cDNA was isolated. The total length of TRIM39 cDNA was 5025 bp. The deduced OnTRIM39 protein contains 549 amino acids and has conserved domains of the TRIM family, which are the RING, B-box, coiled-coil and PRY-SPRY domains. OnTRIM39 mRNA was widely expressed in various tissues. After challenge with Streptococcus agalactiae and stimulation with polyinosinic polycytidylic acid [poly (I:C)] and lipopolysaccharides (LPS), the amount of OnTRIM39 transcript was changed in various tested tissues. OnTRIM39 overexpression increased NF-κB activity. OnTRIM39 was present in the cytoplasm. Mass spectrometry of proteins pulled down with recombinant OnTRIM39 showed that 250 proteins potentially interact with OnTRIM39. The authors selected I3K4I3 from the 250 candidate proteins to verify its interaction with TRIM39. They also selected I3KL45, a member of the same 14-3-3 protein family, to verify its interaction with TRIM39. The results of pull-down assays showed that OnTRIM39 interacted with both I3K413 and I3KL45. These results contribute to further study of the innate immune mechanism of tilapia.

Abstract
The small HERC family currently comprises four members (HERC3-6) involved in the regulation of various physiological activities. Little is known about the role of HERCs in IFN response. In this study, we identify a novel fish HERC member, named crucian carp HERC7, as a negative regulator of fish IFN response. Genome-wide search of homologs and comprehensive phylogenetic analyses reveal that the small HERC family, apart from HERC3-6 that have been well-characterized in mammals, contains a novel HERC7 subfamily exclusively in nonmammalian vertebrates. Lineage-specific and even species-specific expansion of HERC7 subfamily in fish indicates that crucian carp HERC7 might be species-specific. In virally infected fish cells, HERC7 is induced by IFN and selectively targets three retinoic acid-inducible gene-I-like receptor signaling factors for degradation to attenuate IFN response by two distinct strategies. Mechanistically, HERC7 delivers mediator of IFN regulatory factor 3 activator and mitochondrial antiviral signaling protein for proteasome-dependent degradation at the protein level and facilitates IFN regulatory factor 7 transcript decay at the mRNA level, thus abrogating cellular IFN induction to promote virus replication. Whereas HERC7 is a putative E3 ligase, the E3 ligase activity is not required for its negative regulatory function. These results demonstrate that the ongoing expansion of the small HERC family generates a novel HERC7 to fine-tune fish IFN antiviral response.

Abstract
Tripartite motif (TRIM) proteins are a large family of E3 ubiquitin ligases involved in many biological processes, such as inflammation and antiviral immunity. In the present study, a novel TRIM protein homolog named CgTRIM1 was identified from Pacific oyster Crassostrea gigas. The open reading frame (ORF) of CgTRIM1 was of 1914 bp encoding a putative polypeptide of 637 amino acid residues. There were three classical domains in the predicted CgTRIM1 protein, including one RING domain, two b-box domains and one coiled-coil domain in N-terminal. For the lack of C-terminal domains, the CgTRIM1 was classified as the member of C-V TRIM subfamily. The mRNA transcripts of CgTRIM1 were detected in all the tested tissues and haemocytes, with the highest expression level in gill. The mRNA and protein levels of CgTRIM1 in gill were significantly up-regulated at 6 h after poly (I:C) stimulation. Moreover, the nuclear translocation of CgTRIM1 was observed in haemocytes of oysters after poly (I:C) stimulation. After IFN-like protein (CgIFNLP) was knocked down by RNA interference (RNAi), the expression of CgTRIM1 in gill was markedly inhibited in both mRNA (0.14-fold, p < 0.001) and protein levels after poly (I:C) stimulation. Furthermore, after knocking down of CgTRIM1, the mRNA expression levels of IFN-stimulated genes, including myxovirus resistance of oyster (CgMx) and Interferon-induced protein 44 (CgIFI44) were significantly down-regulated post poly (I:C) stimulation, while no significant change of the CgIFNLP expression was observed. These results indicated that CgTRIM1 participated in the antiviral response of C. gigas by regulating the mRNA expressions of IFN-stimulated genes.

Abstract
In mammals, cyclic GMP-AMP synthase (cGAS) recognizes cytosolic dsDNA to induce the type I IFN response. However, the functional role of cGAS in the IFN response of fish remains unclear or controversial. In this study, we report that cGAS orthologs from crucian carp Carassius auratus (CacGAS) and grass carp Ctenopharyngodon idellus (CicGAS) target the dsRNA sensor retinoic acid-inducible gene I (RIG-I) for negative regulation of the IFN response. First, poly(deoxyadenylic-deoxythymidylic) acid-, polyinosinic-polycytidylic acid-, and spring viremia of carp virus-induced IFN responses were impaired by overexpression of CacGAS and CicGAS. Then, CacGAS and CicGAS interacted with CiRIG-I and CiMAVS and inhibited CiRIG-I- and CiMAVS-mediated IFN induction. Moreover, the K63-linked ubiquitination of CiRIG-I and the interaction between CiRIG-I and CiMAVS were attenuated by CacGAS and CicGAS. Finally, CacGAS and CicGAS decreased CiRIG-I-mediated the cellular antiviral response and facilitated viral replication. Taken together, data in this study identify CacGAS and CicGAS as negative regulators in RIG-I-like receptor signaling, which extends the current knowledge regarding the role of fish cGAS in the innate antiviral response.

Integrative Transcriptomic Analysis Reveals the Immune Mechanism for a CyHV-3-Resistant Common Carp Strain. Front Immunol 2021; 12:687151.

Abstract
Anti-disease breeding is becoming the most promising solution to cyprinid herpesvirus-3 (CyHV-3) infection, the major threat to common carp aquaculture. Virus challenging studies suggested that a breeding strain of common carp developed resistance to CyHV-3 infection. This study illustrates the immune mechanisms involved in both sensitivity and anti-virus ability for CyHV3 infection in fish. An integrative analysis of the protein-coding genes and long non-coding RNAs (lncRNAs) using transcriptomic data was performed. Tissues from the head kidney of common carp were extracted at days 0 (the healthy control) and 7 after CyHV-3 infection (the survivors) and used to analyze the transcriptome through both Illumina and PacBio sequencing. Following analysis of the GO terms and KEGG pathways involved, the immune-related terms and pathways were merged. To dig out details on the immune aspect, the DEGs were filtered using the current common carp immune gene library. Immune gene categories and their corresponding genes in different comparison groups were revealed. Also, the immunological Gene Ontology terms for lncRNA modulation were retained. The weighted gene co-expression network analysis was used to reveal the regulation of immune genes by lncRNA. The results demonstrated that the breeding carp strain develops a marked resistance to CyHV-3 infection through a specific innate immune mechanism. The featured biological processes were autophagy, phagocytosis, cytotoxicity, and virus blockage by lectins and MUC3. Moreover, the immune-suppressive signals, such as suppression of IL21R on STAT3, PI3K mediated inhibition of inflammation by dopamine upon infection, as well as the inhibition of NLRC3 on STING during a steady state. Possible susceptible factors for CyHV-3, such as ITGB1, TLR18, and CCL4, were also revealed from the non-breeding strain. The results of this study also suggested that Nramp and PAI regulated by LncRNA could facilitate virus infection and proliferation for infected cells respectively, while T cell leukemia homeobox 3 (TLX3), as well as galectin 3 function by lncRNA, may play a role in the resistance mechanism. Therefore, immune factors that are immunogenetically insensitive or susceptible to CyHV-3 infection have been revealed.

Abstract
Viral nervous necrosis (VNN) is an acute and serious fish disease caused by nervous necrosis virus (NNV) which has been reported massive mortality in more than fifty teleost species worldwide. VNN causes damage of necrosis and vacuolation to central nervous system (CNS) cells in fish. It is difficult to identify the specific type of cell targeted by NNV, and to decipher the host immune response because of the functional diversity and highly complex anatomical and cellular composition of the CNS. In this study, we found that the red spotted grouper NNV (RGNNV) mainly attacked the midbrain of orange-spotted grouper (Epinephelus coioides). We conducted single-cell RNA-seq analysis of the midbrain of healthy and RGNNV-infected fish and identified 35 transcriptionally distinct cell subtypes, including 28 neuronal and 7 non-neuronal cell types. An evaluation of the subpopulations of immune cells revealed that macrophages were enriched in RGNNV-infected fish, and the transcriptional profiles of macrophages indicated an acute cytokine and inflammatory response. Unsupervised pseudotime analysis of immune cells showed that microglia transformed into M1-type activated macrophages to produce cytokines to reduce the damage to nerve tissue caused by the virus. We also found that RGNNV targeted neuronal cell types was GLU1 and GLU3, and we found that the key genes and pathways by which causes cell cytoplasmic vacuoles and autophagy significant enrichment, this may be the major route viruses cause cell death. These data provided a comprehensive transcriptional perspective of the grouper midbrain and the basis for further research on how viruses infect the teleost CNS.

Abstract
At each stage of innate immune response, there are stimulatory and inhibitory signals that modulate the strength and character of the response. RIG-I-like receptor (RLR) signaling pathway plays pivotal roles in antiviral innate immune response. Recent studies have revealed the molecular mechanisms that viral infection leads to the activation of RLRs-mediated downstream signaling cascades and the production of type I interferons (IFNs). However, antiviral immune responses must be tightly regulated in order to prevent detrimental type I IFNs production. Previous reviews have highlighted negative regulation of RLR signaling pathway, which mainly target to directly regulate RIG-I, MDA5, MAVS and TBK1 function in mammals. In this review, we summarize recent advances in our understanding of negative regulators of RLR signaling pathway in teleost, with specific focus on piscine and viral regulatory mechanisms that directly or indirectly inhibit the function of RIG-I, MDA5, LGP2, MAVS, TRAF3, TBK1, IRF3 and IRF7 both in the steady state or upon viral infection. We also further discuss important directions for future studies, especially for non-coding RNAs and post-translational modifications via fish specific TRIM proteins. The knowledge of negative regulators of RLR signaling pathway in teleost will shed new light on the critical information for potential therapeutic purposes.

Abstract
Inflammation is an immune response to exogenous or endogenous insults that helps to maintain the tissue homeostasis under stressful conditions. Depending on the differential types of insults, inflammation is classified into microbial, autoimmune, metabolic, allergic, and physical inflammation. With regard to its involvement in the pathogenesis of most of human diseases, dissecting the key molecules in the regulation of inflammatory process is vital for the prevention and therapeutics of human diseases. Tripartite motif (TRIM) proteins are a versatile family of E3 ligases, which are composed of > 80 distinct members in humans recognized for their roles in antiviral responses. Recently, a large number of studies have shown the regulatory roles of TRIM proteins in mediating the inflammation. Herein in this review, we discuss the aberrations of TRIM proteins in autoimmune and autoinflammatory diseases, with a focus on the regulation of different components of inflammatory process, including inflammasome, NF-κB signaling, type I IFN (interferon) production, and Th1/Th17 cell differentiation. Importantly, elucidation of the mechanism underlying the regulation of inflammation by TRIMs provides insights into the use of TRIMs as therapeutic targets for disease treatment.

Abstract
In mammals, tripartite motif (TRIM)-containing proteins are involved in interferon (IFN)-mediated antiviral response as pivotal players endowed with antiviral effects and modulatory capacity. Teleost fish have a unique subfamily of TRIM, called finTRIM (fish novel TRIM, FTR) generated by genus- or species-specific duplication of TRIM genes. Herein, four TRIM genes are identified from Epithelioma papulosum cyprini (EPC) cells, and phylogenetically close to the members of finTRIM, thus named FTREPC1, FTREPC2, FTREPC3 and FTREPC4. Despite high similarity in nucleotide sequence, FTREPC1/2 genes encode two proteins with a typically consecutive tripartite motif followed by a C-terminal B30.2 domain, while FTREPC3/4-encoding proteins retain only a RING domain due to early termination of translation. They are induced by poly(I:C), GCRV and SVCV as IFN-stimulated genes (ISGs), and this induction is severely impaired by blockade of STAT1 pathway and is dependent on a typical ISRE motif within the 5' untranslated regions (5'UTRs) of FTREPC1/2/3/4 genes. Whereas overexpression of FTREPC1/2/3/4 alone does not activate fish IFN promoters, overexpression of FTREPC1 or FTREPC2, rather than FTREPC3 and FTREPC4, significantly impairs intracellular poly(I:C)-triggered activation of fish IFN promoters. Consistently, FTREPC1/2 promote virus replication through negatively regulating IFN response. Our results provide evidence for the involvement of EPC finTRIM proteins in IFN antiviral response and insights into genus- or species-specific regulation of fish innate immune pathways.

Abstract
TANK-binding kinase 1 (TBK1), an IKK-related serine/threonine kinase, is pivotal for the induction of antiviral type I interferon (IFN) by TLR and RLR signaling pathways. In a previous study, we demonstrated that TBK1 spliced isoforms (TBK1_tv1 and TBK1_tv2) from zebrafish were dominant negative regulators in the RLR antiviral pathway by targeting the functional TBK1–IRF3 complex formation. In this study, we show that the third TBK1 isoform (namely TBK1_tv3) inhibits zebrafish type I IFN production by promoting TBK1 and IRF3 degradation. First, ectopic expression of TBK1_tv3 suppresses poly(I:C)- and Spring viremia of carp virus-induced type I IFN response, and also inhibits the up-regulation of IFN promoter activities stimulated by RIG-I, MDA5, MAVS, TBK1, and IRF3. Second, TBK1_tv3 targets TBK1 and IRF3 to impair the formation of TBK1 dimer, TBK1–IRF3 complex, and IRF3 dimer. Notably, TBK1_tv3 promotes the degradation of TBK1 through the ubiquitin–proteasome pathway and the degradation of IRF3 through the lysosomal pathway. Further analysis demonstrates that TBK1_tv3 promotes the degradation of TBK1 for K48-linked ubiquitination by targeting the K251, K256, and K271 sites of TBK1. Collectively, our results suggest a novel TBK1 isoform-mediated negative regulation mechanism, which serves to balance the production of type I IFN and ISGs.

Abstract
Interferon regulatory factor 7 (IRF7) serves as a critical mediator in the regulation of type Ι interferon (IFN) response to invading pathogens. Here, an ortholog of IRF7 was characterized in yellow catfish (Pelteobagrus fulvidraco). The full-length cDNA of PfIRF7 consisted of 1516 bp encoding a polypeptide of 425 amino acids. PfIRF7 protein comprised a typical IRF structural architecture, including a DNA binding domain (DBD), an IRF association domain (IAD) and a serine-rich domain (SRD). PfIRF7 was expressed predominantly in the immune-related tissues and transcriptionally upregulated by PolyI:C, LPS, and Edwardsiella ictaluri. Ectopic expression of PfIRF7 led to activation of fish type I IFN promoters and induction of IFN and Vig1, thereby conferring a strong antiviral effect against spring viremia of carp virus (SVCV). Overall, the present data suggest that PfIRF7 may play an essential role in type I IFN response of yellow catfish.

Abstract
Fish interferon (IFN)-mediated antiviral innate immunity is the first line of defense against virus invasion. In the present study, we identify two fish IFN genes (here tentatively named IFNa and IFNc) with different-sized 3' UTRs from clone F strain of gibel carp Carassius auratus gibelio. Carp IFNa has a relatively short 3'UTR without AU-rich elements (AREs) but IFNc has a long one with 9 AREs. Functionally, carp IFNa and IFNc display significantly antiviral potential to viral infection, likely through induction of downstream IFN-stimulated genes (ISGs). Both carp IFN genes are induced by viral infection, poly(I:C) treatment and IRF3/7, which are ascribed to the IFN-sensitive response elements (ISRE) within their promoters. Carp IFN genes are also induced by each other and by themselves, indicating existence of a positive feedback loop in fish IFN-mediated antiviral immune response. Comparative analyses of 3'UTR-mediated expression regulation at mRNA and protein levels show that the ARE-containing 3'UTR of carp IFNc rather than the short 3'UTR of carp IFNa promotes mRNA decay but instead results in high-level protein expression, indicating that 3'UTR of fish IFN mRNAs might be a potential factor for regulation of IFN-mediated antiviral immune response. Considering a fact that a given protein function is largely related to its protein level, these results suggest that both promoter and 3'UTR contribute to the transcription and translation of fish IFN genes, thus shaping their eventually antiviral potential.
