Abstract
Numerous tripartite motif (TRIM) proteins, identified as E3 ubiquitin ligases, participate in various viral infections through ubiquitylation, ISGylation, and SUMOylation processes. Respiratory viruses, particularly influenza A virus (IAV) and respiratory coronaviruses (CoVs), have severely threatened public health with high morbidity and mortality, causing incalculable losses. Research on the regulation of TRIM proteins in respiratory virus infections is crucial for disease prevention and control. This review introduces TRIM proteins, summarizes recent discoveries regarding their roles and molecular mechanisms in IAV and CoVs infections, discusses current research gaps, and explores potential future trends in this rapidly developing field. It aims to enhance understanding of virus-host interactions and inform the development of new molecularly targeted therapies.

TRIM21 and Fc-engineered antibodies: decoding its complex antibody binding mode with implications for viral neutralization. Front Immunol 2024; 15:1401471. [PMID: 38938560 PMCID: PMC11210195 DOI: 10.3389/fimmu.2024.1401471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Accepted: 05/29/2024] [Indexed: 06/29/2024] Open
Abstract
TRIM21 is a pivotal effector in the immune system, orchestrating antibody-mediated responses and modulating immune signaling. In this comprehensive study, we focus on the interaction of TRIM21 with Fc engineered antibodies and subsequent implications for viral neutralization. Through a series of analytical techniques, including biosensor assays, mass photometry, and electron microscopy, along with structure predictions, we unravel the intricate mechanisms governing the interplay between TRIM21 and antibodies. Our investigations reveal that the TRIM21 capacity to recognize, bind, and facilitate the proteasomal degradation of antibody-coated viruses is critically dependent on the affinity and avidity interplay of its interactions with antibody Fc regions. We suggest a novel binding mechanism, where TRIM21 binding to one Fc site results in the detachment of PRYSPRY from the coiled-coil domain, enhancing mobility due to its flexible linker, thereby facilitating the engagement of the second site, resulting in avidity due to bivalent engagement. These findings shed light on the dual role of TRIM21 in antiviral immunity, both in recognizing and directing viruses for intracellular degradation, and demonstrate its potential for therapeutic exploitation. The study advances our understanding of intracellular immune responses and opens new avenues for the development of antiviral strategies and innovation in tailored effector functions designed to leverage TRIM21s unique binding mode.

BMC Genomics 2024; 25:459.

Abstract
BACKGROUND Genome-wide comparisons of populations are widely used to explore the patterns of nucleotide diversity and sequence divergence to provide knowledge on how natural selection and genetic drift affect the genome. In this study we have compared whole-genome sequencing data from Atlantic and Pacific herring, two sister species that diverged about 2 million years ago, to explore the pattern of genetic differentiation between the two species. RESULTS The genome comparison of the two species revealed high genome-wide differentiation but with islands of remarkably low genetic differentiation, as measured by an FST analysis. However, the low FST observed in these islands is not caused by low interspecies sequence divergence (dxy) but rather by exceptionally high estimated intraspecies nucleotide diversity (π). These regions of low differentiation and elevated nucleotide diversity, termed high-diversity regions in this study, are not enriched for repeats but are highly enriched for immune-related genes. This enrichment includes genes from both the adaptive immune system, such as immunoglobulin, T-cell receptor and major histocompatibility complex genes, as well as a substantial number of genes with a role in the innate immune system, e.g. novel immune-type receptor, tripartite motif and tumor necrosis factor receptor genes. Analysis of long-read based assemblies from two Atlantic herring individuals revealed extensive copy number variation in these genomic regions, indicating that the elevated intraspecies nucleotide diversities were partially due to the cross-mapping of short reads. CONCLUSIONS This study demonstrates that copy number variation is a characteristic feature of immune trait loci in herring. Another important implication is that these loci are blind spots in classical genome-wide screens for genetic differentiation using short-read data, not only in herring, likely also in other species harboring qualitatively similar variation at immune trait loci. These loci stood out in this study because of the relatively high genome-wide baseline for FST values between Atlantic and Pacific herring.

Abstract
Host antiviral proteins inhibit primate lentiviruses and other retroviruses by targeting many features of the viral life cycle. The lentiviral capsid protein and the assembled viral core are known to be inhibited through multiple, directly acting antiviral proteins. Several phenotypes, including those known as Lv1 through Lv5, have been described as cell type-specific blocks to infection against some but not all primate lentiviruses. Here we review important features of known capsid-targeting blocks to infection together with several blocks to infection for which the genes responsible for the inhibition still remain to be identified. We outline the features of these blocks as well as how current methodologies are now well suited to find these antiviral genes and solve these long-standing mysteries in the HIV and retrovirology fields.

Characterization of two tripartite motif-containing genes from Asian Seabass Lates calcarifer and their expression in response to virus infection and microbial molecular motifs. JOURNAL OF AQUATIC ANIMAL HEALTH 2023; 35:169-186. [PMID: 37139802 DOI: 10.1002/aah.10187] [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: 01/08/2023] [Revised: 03/31/2023] [Accepted: 04/29/2023] [Indexed: 05/05/2023]
Abstract
OBJECTIVE We identified two tripartite motif (TRIM) genes, LcTRIM21 and LcTRIM39, from the Asian Seabass Lates calcarifer, and examined their responses to experimental betanodavirus infection and stimulation with microbial pathogen-associated molecular patterns. METHODS Genes encoding LcTRIM21 and LcTRIM39 were identified, cloned, and sequenced from the Asian Seabass. We analyzed the sequence using a variety of bioinformatics tools to determine protein structure, localization, and establish a phylogenetic tree. By using quantitative real-time PCR, we analyzed expression profiles of the LcTRIM21 and LcTRIM39 genes in response to betanodavirus challenge as well as molecular pathogen-associated molecular patterns like poly(I:C) and Zymosan A. The tissue distribution pattern of these genes was also examined in healthy animals. RESULT Asian Seabass homologues of the TRIM gene, LcTRIM21 and LcTRIM39, were cloned, both encoding proteins with 547 amino acids. LcTRIM21 is predicted to have an isoelectric point of 6.32 and a molecular mass of 62.11 kilodaltons, while LcTRIM39 has an isoelectric point of 5.57 and a molecular mass of 62.11 kilodaltons. LcTRIM21 and LcTRIM39 homologues were predicted to be localized in cytoplasm by in silico protein localization. Structurally, both proteins contain an N-terminal really interesting new gene (RING) zinc-finger domain, B-box domain, coiled-coil domain and C-terminal PRY/SPRY domain. Most tissues and organs examined showed constitutive expression of LcTRIM21 and LcTRIM39. Upon poly(I:C) challenge or red-spotted grouper nervous necrosis virus infection, LcTRIM21 and LcTRIM39 mRNA expression was significantly upregulated, suggesting that they may play a critical antiviral role against fish viruses. LcTRIM21 and LcTRIM39 expression were also upregulated by administration of the glucan Zymosan A. CONCLUSION The TRIM-containing gene is an E3 ubiquitin ligase that exhibits antiviral activity by targeting viral proteins via proteasome-mediated ubiquitination. TRIM proteins can be explored for the discovery of antivirals and strategies to combat diseases like viral nervous necrosis, that threaten seabass aquaculture.

Abstract
Tripartite motif (TRIM) proteins are involved in development, innate immunity, and viral restriction. TRIM gene repertoires vary between species, likely due to diversification caused by selective pressures from pathogens; however, this has not been explored in birds. We mined a de novo assembled transcriptome for the TRIM gene repertoire of the domestic mallard duck (Anas platyrhynchos), a reservoir host of influenza A viruses. We found 57 TRIM genes in the duck, which represent all 12 subfamilies based on their C-terminal domains. Members of the C-IV subfamily with C-terminal PRY-SPRY domains are known to augment immune responses in mammals. We compared C-IV TRIM proteins between reptiles, birds, and mammals and show that many C-IV subfamily members have arisen independently in these lineages. A comparison of the MHC-linked C-IV TRIM genes reveals expansions in birds and reptiles. The TRIM25 locus with related innate receptor modifiers is adjacent to the MHC in reptile and marsupial genomes, suggesting the ancestral organization. Within the avian lineage, both the MHC and TRIM25 loci have undergone significant TRIM gene reorganizations and divergence, both hallmarks of pathogen-driven selection. To assess the expression of TRIM genes, we aligned RNA-seq reads from duck tissues. C-IV TRIMs had high relative expression in immune relevant sites such as the lung, spleen, kidney, and intestine, and low expression in immune privileged sites such as in the brain or gonads. Gene loss and gain in the evolution of the TRIM repertoire in birds suggests candidate immune genes and potential targets of viral subversion.

Abstract
Cys2-His2 zinc finger genes (ZNFs) form the largest family of transcription factors in metazoans. ZNF evolution is highly dynamic and characterized by the rapid expansion and contraction of numerous subfamilies across the animal phylogeny. The forces and mechanisms underlying rapid ZNF evolution remain poorly understood, but there is growing evidence that, in tetrapods, the targeting and repression of lineage-specific transposable elements (TEs) plays a critical role in the evolution of the Krüppel-associated box ZNF (KZNF) subfamily. Currently, it is unknown whether this function and coevolutionary relationship is unique to KZNFs or is a broader feature of metazoan ZNFs. Here, we present evidence that genomic conflict with TEs has been a central driver of the diversification of ZNFs in animals. Sampling from 3221 genome assemblies, we show that the copy number of retroelements correlates with that of ZNFs across at least 750 million years of metazoan evolution. Using computational predictions, we show that ZNFs preferentially bind TEs in diverse animal species. We further investigate the largest ZNF subfamily found in cyprinid fish, which is characterized by a conserved sequence we dubbed the fish N-terminal zinc finger-associated (FiNZ) domain. Zebrafish possess approximately 700 FiNZ-ZNFs, many of which are evolving adaptively under positive selection. Like mammalian KZNFs, most zebrafish FiNZ-ZNFs are expressed at the onset of zygotic genome activation, and blocking their translation using morpholinos during early embryogenesis results in derepression of transcriptionally active TEs. Together, these data suggest that ZNF diversification has been intimately connected to TE expansion throughout animal evolution.

Abstract
Antiviral innate immunity is orchestrated by the interferon system, which appeared in ancestors of jawed vertebrates. Interferon upregulation induces hundreds of interferon-stimulated-genes (ISGs) with effector or regulatory functions. Here we investigated the evolutionary diversification of ISG responses through comparison of two salmonid fishes, accounting for the impact of sequential whole genome duplications ancestral to teleosts and salmonids. We analysed the transcriptomic response of the IFN pathway in the head kidney of rainbow trout and Atlantic salmon, which separated 25-30 Mya. We identified a large set of ISGs conserved in both species and cross-referenced them with zebrafish and human ISGs. In contrast, around one-third of salmonid ISG lacked orthologs in human, mouse, chicken or frog, and often between rainbow trout and Atlantic salmon, revealing a fast-evolving, lineage-specific arm of the antiviral response. This study also provides a key resource for in-depth functional analysis of ISGs in salmonids of commercial significance.

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.

Abstract
Damages of sensory hair cells (HCs) are mainly responsible for sensorineural hearing loss, while the pathological mechanism remains not fully understood due to the many potential deafness genes unidentified. ftr82, a member of the largely TRIMs family in fish, has been found specifically expressed in the otic vesicle while its function is still unclear. Here, we investigate the roles of ftr82 in HC development and hearing function utilizing the zebrafish model. The results of in situ hybridization illustrate that ftr82 is always restricted to localize in otic vesicles at different stages. The defects of HCs are observed both in ftr82 morphants and mutants, including significantly decreased crista HCs, shortened cilia as well as remarkably reduced functional HCs in neuromasts, which could be successfully rescued by co-injection of exogenous ftr82 mRNA. The behavior assay of startle response indicates that larvae lacking of ftr82 exhibits lower sensitivity to external sound stimuli. Further research reveals that the loss of HCs is mainly caused by cell apoptosis mediated by caspase-3 activation. Our study demonstrates that ftr82 is a crucial hearing-related gene that regulates the HC morphogenesis and auditory function performing, which provides new insight into the rapid identification of the deafness gene.

Abstract
Tripartite motif (TRIM) proteins comprise a large family of RING-type ubiquitin E3 ligases that regulate important biological processes. In this study, full-length MnTRIM32 cDNA was obtained from oriental river prawn Macrobrachium nipponense, and eight MnTRIM32 isoforms generated by alternative splicing were identified. The open reading frames of the eight MnTRIM32 isoforms were predicted to be separately composed of 402, 346, 347, 346, 414, 358, 359, and 358 amino acid residues. Protein structural analysis revealed that all MnTRIM32 isoforms contained a RING domain and a coiled coil region. MnTRIM32 was ubiquitously expressed in all tissues tested, with the highest expression in the hepatopancreas. The mRNA levels of MnTRIM32 in the gills, stomach, and intestine of prawns were found to undergo time-dependent enhancement following white spot syndrome virus (WSSV) stimulation. Double-stranded RNA interference studies revealed that MnTRIM32 silencing significantly downregulated the expression levels of interferon (IFN) regulatory factor MnIRF, IFN-like factor MnVago4, and tumor necrosis factor MnTNF. Furthermore, knockdown of MnTRIM32 in WSSV-challenged prawns increased the expression of VP28 and the number of WSSV copies, suggesting that MnTRIM32 plays a positive role in limiting WSSV infection. These findings provided strong evidence for the important role of MnTRIM32 in the antiviral innate immunity of M. nipponense.

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
TRIM (tripartite motif) proteins have been demonstrated to exert critical roles in host defense against different microbial pathogens. Among them, TRIM23 acts as an important regulatory factor in antiviral immune and inflammatory responses, but the roles of fish TRIM23 against virus infection still remain largely unknown. Here, we investigated the characteristics of TRIM23 homolog from orange spotted grouper (Epinephelus coioides) (EcTRIM23). EcTRIM23 encoded a 580 amino acid peptide, which shared 93.1%, 89.73% and 86.36% identity with golden perch (Perca flavescens), zebrafish (Danio rerio) and human (Homo sapiens), respectively. The transcription levels of EcTRIM23 were significantly up-regulated in response to Singapore grouper iridovirus (SGIV) and red-spotted grouper nervous necrosis virus (RGNNV) infection. EcTRIM23 overexpression in vitro significantly inhibited RGNNV and SGIV replication, evidenced by the delayed cytopathic effect (CPE) progression and the decreased expression of viral core genes. EcTRIM23 significantly increased the expression levels of interferon (IFN) related signaling molecules and pro-inflammatory cytokines, as well as the promoter activities of IFN and NF-κB, suggesting that EcTRIM23 exerted antiviral function by positively regulating host IFN response. Exogenous EcTRIM23 exhibited either diffuse or aggregated localization in grouper cells. After co-transfection, TANK binding kinase 1 (TBK1), TNF receptor associated factor (TRAF) 3 and TRAF4, TRAF5 and TRAF6 were found to interact with EcTRIM23 in grouper cells. Moreover, these proteins could be recruited and co-localized with EcTRIM23 in vitro. Together, our results demonstrated that fish TRIM23 exerted antiviral activity against fish viruses by interacting with multiple host proteins to regulate immune responses.

Abstract
Tripartite motif-containing (TRIM) proteins are conserved throughout the metazoan kingdom, and the TRIM subset finTRIM is highly diversified in fish. We isolated TRIM16 cDNA, a member of the finTRIM family, from the olive flounder Paralichthys olivaceus (PoTRIM16). PoTRIM16 contained a 1,725-bp coding sequence encoding a 574-amino acid polypeptide, which in turn contained a really interesting new gene (RING) finger domain, B-box-type zinc finger (B-BOX), nuclease SbcCD subunit C (SbcC), structural maintenance of chromosome (SMC prok B), and stonustoxin (SNTX) subunit alpha (SPRY-PRY-SNTX). Multiple alignment of related sequences revealed that PoTRIM16 showed 86.63-97.40% identity with fish orthologues, and a phylogenetic tree was constructed of vertebrates. PoTRIM16 mRNA was detected in all tissues examined; levels were highest in the eye and ovary. PoTRIM16 mRNA expression was investigated during early development. Under VHSV infection, PoTRIM16 mRNA was downregulated in the liver of P. olivaceus. This is the first study to characterize fish-specific finTRIM in P. olivaceus, which may play a role in the immune response against virus infection.

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.

Leafy and weedy seadragon genomes connect genic and repetitive DNA features to the extravagant biology of syngnathid fishes. Proc Natl Acad Sci U S A 2022; 119:e2119602119.

Abstract
Seadragons are widely recognized for their derived traits, which include leaf-like appendages and extreme spinal curvature. Efforts to understand the genetic basis of these unique traits and conserve these species and their relatives have been limited by genomic resource gaps. In this paper we present full, annotated genomes of leafy and weedy seadragons, which we use to uncover surprising features of gene family and genome architecture evolution that likely relate to the extravagant phenotypic traits of seadragons and their pipefish and seahorse relatives. These genomes and their analyses are important advances for the study of elaborate vertebrate traits, leveraging this diverse, morphologically exceptional group of fishes. Seadragons are a remarkable lineage of teleost fishes in the family Syngnathidae, renowned for having evolved male pregnancy. Comprising three known species, seadragons are widely recognized and admired for their fantastical body forms and coloration, and their specific habitat requirements have made them flagship representatives for marine conservation and natural history interests. Until recently, a gap has been the lack of significant genomic resources for seadragons. We have produced gene-annotated, chromosome-scale genome models for the leafy and weedy seadragon to advance investigations of evolutionary innovation and elaboration of morphological traits in seadragons as well as their pipefish and seahorse relatives. We identified several interesting features specific to seadragon genomes, including divergent noncoding regions near a developmental gene important for integumentary outgrowth, a high genome-wide density of repetitive DNA, and recent expansions of transposable elements and a vesicular trafficking gene family. Surprisingly, comparative analyses leveraging the seadragon genomes and additional syngnathid and outgroup genomes revealed striking, syngnathid-specific losses in the family of fibroblast growth factors (FGFs), which likely involve reorganization of highly conserved gene regulatory networks in ways that have not previously been documented in natural populations. The resources presented here serve as important tools for future evolutionary studies of developmental processes in syngnathids and hold value for conservation of the extravagant seadragons and their relatives.

Abstract
Fish are an interesting taxon comprising species adapted to a wide range of environments. In this work, we analyzed the transcriptional contribution of transposable elements (TEs) in the gill transcriptomes of three fish species exposed to different salinity conditions. We considered the giant marbled eel Anguilla marmorata and the chum salmon Oncorhynchus keta, both diadromous, and the marine medaka Oryzias melastigma, an euryhaline organism sensu stricto. Our analyses revealed an interesting activity of TEs in the case of juvenile eels, commonly adapted to salty water, when exposed to brackish and freshwater conditions. Moreover, the expression assessment of genes involved in TE silencing mechanisms (six in heterochromatin formation, fourteen known to be part of the nucleosome remodeling deacetylase (NuRD) complex, and four of the Argonaute subfamily) unveiled that they are active. Finally, our results evidenced for the first time a krüppel-associated box (KRAB)-like domain specific to actinopterygians that, together with TRIM33, might allow the functioning of NuRD complex also in fish species. The possible interaction between these two proteins was supported by structural prediction analyses.

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
BACKGROUND The formation and functioning of muscles are fundamental aspects of animal biology, and the evolution of 'muscle genes' is central to our understanding of this tissue. Feeding-fasting-refeeding experiments have been widely used to assess muscle cellular and metabolic responses to nutrition. Though these studies have focused on vertebrate models and only a few invertebrate systems, they have found similar processes are involved in muscle degradation and maintenance. Motivation for these studies stems from interest in diseases whose pathologies involve muscle atrophy, a symptom also triggered by fasting, as well as commercial interest in the muscle mass of animals kept for consumption. Experimentally modelling atrophy by manipulating nutritional state causes muscle mass to be depleted during starvation and replenished with refeeding so that the genetic mechanisms controlling muscle growth and degradation can be understood. RESULTS Using amphioxus, the earliest branching chordate lineage, we address the gap in previous work stemming from comparisons between distantly related vertebrate and invertebrate models. Our amphioxus feeding-fasting-refeeding muscle transcriptomes reveal a highly conserved myogenic program and that the pro-orthologues of many vertebrate myoblast fusion genes were present in the ancestral chordate, despite these invertebrate chordates having unfused mononucleate myocytes. We found that genes differentially expressed between fed and fasted amphioxus were orthologous to the genes that respond to nutritional state in vertebrates. This response is driven in a large part by the highly conserved IGF/Akt/FOXO pathway, where depleted nutrient levels result in activation of FOXO, a transcription factor with many autophagy-related gene targets. CONCLUSION Reconstruction of these gene networks and pathways in amphioxus muscle provides a key point of comparison between the distantly related groups assessed thus far, significantly refining the reconstruction of the ancestral state for chordate myoblast fusion genes and identifying the extensive role of duplicated genes in the IGF/Akt/FOXO pathway across animals. Our study elucidates the evolutionary trajectory of muscle genes as they relate to the increased complexity of vertebrate muscles and muscle development.

Abstract
Tripartite motif 35 (TRIM35) protein is a ubiquitin E3 ligase that mediates interferon-beta (IFN-β) production via regulating ubiquitination of multiple adaptor proteins in innate immune signaling pathways. Here, we cloned the porcine TRIM35 (porTRIM35) gene and analyzed its involvement in IFN-β expression as well as the antiviral response against Japanese encephalitis virus (JEV). The full-length porTRIM35 gene encoded a 493-amino acid protein and exhibited 79.6%-89.5% sequence similarity with its orthologues in humans, mice, monkeys and rabbits. porTRIM35 possessed typical structural features of TRIMs, including a RING domain, a B-box domain, a coiled-coil domain and a PRY/SPYR domain. Exogenous overexpression of porTRIM35 significantly up-regulated the mRNA expression level of IFN-β in swine testicular (ST) cell in response to poly(I:C) stimulation, whereas knockdown endogenous expression of porTRIM35 lead to a decrease in the expression level of IFN-β. Mechanically, porTRIM35 directly interacted with porcine TNF-receptor associated factor 3 (TRAF3) and catalyzed its Lys63-linked polyubiquitination, thereby leading to the up-regulation of IFN-β production. Meanwhile, we demonstrated that the RING and PRY/SPRY domains were essential for the E3 ligase activity of porTRIM35. In response to JEV infection, the endogenous expression of porTRIM35 was markedly inhibited at the mRNA level, while exogenous expression of porTRIM35 significantly elevated the expression of IFN-β induced by JEV infection and reduced viral titers in ST cells, suggesting that porTRIM35 is a negative regulator for JEV replication. These data demonstrate the importance of porTRIM35 in IFN-β expression as well as the antiviral response against JEV replication.

Recurrent expansions of B30.2-associated immune receptor families in fish. Immunogenetics 2021; 74:129-147. [PMID: 34850255 DOI: 10.1007/s00251-021-01235-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Accepted: 11/16/2021] [Indexed: 12/12/2022]
Abstract
B30.2 domains, also known as PRY/SPRY, are key components of specific subsets of two large families of proteins involved in innate immunity: the tripartite motif proteins (TRIMs) and the Nod-like receptors (NLRs). TRIM proteins are important, often inducible factors of antiviral innate immunity, targeting multiple steps of viral cycles through a variety of mechanisms. NLRs prime and regulate systemic innate defenses, especially against bacteria, and control inflammation. Large TRIM and NLR subsets characterized by the presence of a B30.2 domain have been reported from a few fish species including zebrafish and seem to be strongly prone to gene duplication/expansion. Here, we performed a large-scale survey of these receptors across about 150 fish genomes, focusing on ray-finned fishes. We assessed the number and genomic distribution of domains and domain combinations associated with TRIMs, NLRs, and other genes containing B30.2 domains and looked for gene expansion patterns across fish groups. We then used a model to test the impact of taxonomy, genome size, and environmental variables on the copy numbers of these genes. Our findings reveal novel domain structures, clade-specific gains and losses. They also assist with the timing of the gene expansions, reveal patterns associated with the MHC, and lay the groundwork for further studies delving deeper into the forces that drive the copy number variation of immune genes on a species level.

Abstract
Tripartite motif proteins (TRIMs), especially B30.2 domain-containing TRIMs (TRIMs-B30.2), are increasingly well known for their antiviral immune functions in mammals, while antiviral TRIMs are far from being identified in teleosts. In the present study, we identified a total of 42 CiTRIMs from the genome of grass carp, Ctenopharyngodon idella, an important cultured teleost in China, based on hmmsearch and SMART analysis. Among these CiTRIMs, the gene loci of 37 CiTRIMs were located on different chromosomes and shared gene collinearities with homologous counterparts from human and zebrafish genomes. They possessed intact conserved RBCC or RB domain assemblies at their N-termini and eight different domains, including the B30.2 domain, at their C-termini. A total of 19 TRIMs-B30.2 were identified, and most of them were clustered into a large branch of CiTRIMs in the dendrogram. Tissue expression analysis showed that 42 CiTRIMs were universally expressed in various grass carp tissues. A total of 11 significantly differentially expressed CiTRIMs were found in two sets of grass carp transcriptomes during grass carp reovirus (GCRV) infection. Three of them, including Cibtr40, CiTRIM103 and CiTRIM109, which all belonged to TRIMs-B30.2, were associated with the type I interferon response during GCRV infection by weighted network co-expression and gene expression trend analyses, suggesting their involvement in antiviral immunity. These findings may offer useful information for understanding the structure, evolution, and function of TRIMs in teleosts and provide potential antiviral immune molecule markers for grass carp.

Abstract
Extensive crosstalk exists between autophagy and innate immune signalling pathways. The stimuli that induce pattern recognition receptor (PRR)-mediated innate immune signalling pathways, also upregulate autophagy. The purpose of this increased autophagy is to eliminate the stimuli and/or suppress the inflammatory pathways by targeted degradation of PRRs or intermediary proteins (termed 'inflammophagy'). By executing these functions, autophagy dampens excess inflammation triggered by the innate immune signalling pathways. Thus, autophagy helps in the maintenance of the body's innate immune homeostasis to protect from inflammatory and autoimmune diseases. Many autophagy-dependent mechanisms that could control innate immune signalling have been studied over the last few years. However, still, the understanding is incomplete, and studies that are more systematic should be undertaken to delineate the mechanisms of inflammophagy. Here, we discuss the available knowledge of crosstalk between autophagy and PRR signalling pathways.

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
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
Vaccine adjuvants induce host innate immune responses improving long-lasting adaptive immunity against vaccine antigens. In vitro models can be used to compare these responses between adjuvants and the infection targeted by the vaccine. We utilized transcriptomic profiling of an Atlantic salmon cell line to compare innate immune responses against ISAV and an experimental viral vaccine adjuvant: poly (I:C). Induction of interferon and interferon induced genes were observed after both treatments, but often with different amplitude and kinetics. Using KEGG ortholog database and available software from Bioconductor we could specify a complete bioinformatic pipeline for analysis of transcriptomic data from Atlantic salmon, a feature not previously available. We have identified important differences in the transcriptional profile of Atlantic salmon cells exposed to viral infection and a viral vaccine adjuvant candidate, poly (I:C). This report increases our knowledge of viral host-pathogen interaction in salmon and to which extent these can be mimicked by adjuvant compounds.

Abstract
Microglia are tissue-resident macrophages in the central nervous system (CNS) that play essential roles in the regulation of CNS development and homeostasis. Yet, the genetic networks governing microglia development remain incompletely defined. Here, we report the identification and characterization of a microglia-defective zebrafish mutant wulonghkz12 (wulhkz12 ) isolated from an ethylnitrosourea (ENU)-based genetic screen. We show that wulhkz12 mutants harbors a missense point mutation in the gene region encoding the PRY/SPRY domain of the tripartite-motif family protein 35-28 (trim35-28) gene. Time-lapse imaging revealed that the loss of Trim35-28 function causes lytic necrosis of microglial precursors/peripheral macrophages, as indicated by cytoplasmic swelling and membrane rupture of these precursors and accompanied by neutrophil infiltration and systemic inflammation. Intriguingly, the lytic necrosis of microglial precursors in trim35-28-deficient mutants appeared to depend neither on the canonical pyroptotic nor necroptotic pathways, as inhibition of the key component in each pathway could not rescue the microglia phenotype in trim35-28-deficient mutants. Finally, results from tissue-specific rescue experiments suggested that Trim35-28 acts cell-autonomously in the survival of microglial precursors. Taken together, the findings of our study reveal Trim35-28 as a regulatory protein essential for microglia development.

Abstract
The tripartite motif (TRIM) gene family encodes diverse distinct proteins that play important roles in many biological processes. However, the molecular evolution and phylogenetic relationships of TRIM genes in primates are still elusive. We performed a genomic approach to identify and characterize TRIM genes in human and other six primate genomes. In total, 537 putative functional TRIM genes were identified and TRIM members varied among primates. A neighbor joining (NJ) tree based on the protein sequences of 82 human TRIM genes indicates seven TRIM groups, which is consistent with the results based on the architectural motifs. Many TRIM gene duplication events were identified, indicating a recent expansion of TRIM family in primate lineages. Interestingly, the chimpanzee genome shows the greatest TRIM gene expansion among the primates; however, its congeneric species, bonobo, has the least number of TRIM genes and no duplication event. Moreover, we identified a ~ 200 kb deletion on chromosome 11 of bonobos that results in a loss of cluster3 TRIM genes. The loss of TRIM genes might have occurred within the last 2 mys. Analysis of positive selection recovered 9 previously reported and 21 newly identified positively selected TRIM genes. In particular, most positive selected sites are located in the B30.2 domains. Our results have provided new insight into the evolution of primate TRIM genes and will broaden our understanding on the functions of the TRIM family.

Abstract
Autophagy, a main intracellular catabolic process, is induced in response to a variety of cellular stresses to promptly degrade harmful agents and to coordinate the activity of prosurvival and prodeath processes in order to determine the fate of the injured cells. While the main components of the autophagy machinery are well characterized, the molecular mechanisms that confer selectivity to this process both in terms of stress detection and cargo engulfment have only been partly elucidated. Here, we discuss the emerging role played by the E3 ubiquitin ligases of the TRIM family in regulating autophagy in physiological and pathological conditions, such as inflammation, infection, tumorigenesis, and muscle atrophy. TRIM proteins employ different strategies to regulate the activity of the core autophagy machinery, acting either as scaffold proteins or via ubiquitin-mediated mechanisms. Moreover, they confer high selectivity to the autophagy-mediated degradation as described for the innate immune response, where TRIM proteins mediate both the engulfment of pathogens within autophagosomes and modulate the immune response by controlling the stability of signaling regulators. Importantly, the elucidation of the molecular mechanisms underlying the regulation of autophagy by TRIMs is providing important insights into how selective types of autophagy are altered under pathological conditions, as recently shown in cancer and muscular dystrophy.

Abstract
Evolution of cellular innate immune genes in response to viral threats represents a rich area of study for understanding complex events that shape mammalian genomes. One of these genes, TRIM5, is a retroviral restriction factor that mediates a post-entry block to infection. Previous studies on the genomic cluster that contains TRIM5 identified different patterns of gene amplification and the independent birth of CypA gene fusions in various primate species. However, the evolution of Trim5 in the largest order of mammals, Rodentia, remains poorly characterized. Here, we present an expansive phylogenetic and genomic analysis of the Trim5 cluster in rodents. Our findings reveal substantial evolutionary changes including gene amplifications, rearrangements, loss and fusion. We describe the first independent evolution of TrimCyp fusion genes in rodents. We show that the TrimCyp gene found in some Peromyscus species was acquired about 2 million years ago. When ectopically expressed, the P. maniculatus TRIMCyp shows anti-retroviral activity that is reversed by cyclosporine, but it does not activate Nf-κB or AP-1 promoters, unlike the primate TRIMCyps. These results describe a complex pattern of differential gene amplification in the Trim5 cluster of rodents and identify the first functional TrimCyp fusion gene outside of primates and tree shrews.

Abstract
In mammals and fish, emerging evidence highlights that TRIM family members play important roles in the interferon (IFN) antiviral immune response. Fish TRIM family has undergone an unprecedented expansion leading to generation of finTRIM subfamily, which is exclusively specific to fish. Our recent results have shown that FTRCA1 (finTRIM C. auratus 1) is likely a fish species-specific finTRIM member in crucian carp C. auratus and acts as a negative modulator to downregulate fish IFN response by autophage-lysosomal degradation of protein kinase TBK1. In the present study, we found that FTRCA1 also impedes the activation of crucian carp IFN promoter by IRF7 but not by IRF3. Mechanistically, FTRCA1 attenuates IRF7 transcription levels likely due to enhanced decay of IRF7 mRNA, leading to reduced IRF7 protein levels and subsequently reduced fish IFN expression. E3 ligase activity is required for FTRCA1 to negatively regulate IRF7-mediated IFN response, because ligase-inactive mutants and the RING-deleted mutant of FTRCA1 lose the ability to block the activation of crucian carp IFN promoter by IRF7. These results together indicate that FTRCA1 is a multifaceted modulator to target different signaling factors for shaping fish IFN response in crucian carp.

Abstract
Global aquaculture production continues to increase rapidly. One of the most important species of marine fish currently cultivated in Southern Europe is Solea senegalensis, reaching more than 300 Tn in 2017. In the present work, 14 Bacterial Artificial Chromosome (BAC) clones containing candidate genes involved in the immune system (b2m, il10, tlr3, tap1, tnfα, tlr8, trim25, lysg, irf5, hmgb2, calr, trim16, and mx), were examined and compared with other species using multicolor Fluorescence in situ Hybridization (mFISH), massive sequencing and bioinformatic analysis to determine the genomic surroundings and syntenic chromosomal conservation of the genomic region contained in each BAC clone. The mFISH showed that the groups of genes hmgb2-trim25-irf5-b2m; tlr3-lysg; tnfα-tap1, and il10-mx-trim16 were co-localized on the same chromosomes. Synteny results suggested that the studied BACs are placed in a smaller number of chromosomes in S. senegalensis that in other species. Phylogenetic analyses suggested that the evolutionary rate of immune system genes studied is similar among the taxa studied, given that the clustering obtained was in accordance with the accepted phylogenetic relationships among these species. This study contributes to a better understanding of the structure and function of the immune system of the Senegalese sole, which is essential for the development of new technologies and products to improve fish health and productivity.

Abstract
Tripartite motif (TRIM) proteins are key components of the innate immune system, functioning as antiviral restriction factors or modulating signaling cascades that lead to proinflammatory cytokine induction. In the present study, the TRIM family gene TRIM23 from grass carp (Ctenopharyngodon idella) was cloned and characterised. TRIM23 was moderately expressed in the examined tissues, and the significantly altered expression was observed after grass carp reovirus (GCRV) and poly(I:C) infection. Dual-luciferase activity assay showed that TRIM23, especially its C-terminal domain ARF, depressed the promoter activity of IRF3 and IRF7. The subcellular localisation showed that TRIM23 protein was located in the cytoplasm and could be recruited by both TRAF6 and MyD88. Furthermore, TRIM23 was confirmed to interact with either TRAF6 or MyD88 by the bimolecular fluorescence complementation (BiFC) system in CIK cells. Additionally, autophagy was enhanced by over-expressed TRIM23 in 293T cells. Taken together, our results demonstrate that TRIM23 gene plays an important role in innate immune regulation and provide new insights into understanding the functional characteristics of the TRIM23 in teleosts.

Abstract
In mammals, tripartite motif (TRIM) proteins have emerged as pivotal players endowed with, directly, antiviral effects and, indirectly, modulatory capacity of the innate immune response. An unprecedented expansion of TRIM family has occurred in fish; however, the functional role of fish TRIM family members remains largely unknown. In this study, we identify a species-specific TRIM gene from crucian carp Carassius auratus, named FTRCA1, phylogenetically similar to the members of finTRIM, a subfamily of TRIM exclusively in teleost fish. FTRCA1 is induced by IFN and IFN stimuli as a typical IFN-stimulated gene. Overexpression of FTRCA1 negatively regulates IFN antiviral response by inhibition of IRF3 phosphorylation; consistently, knockdown of FTRCA1 results in enhanced levels of IRF3 phosphorylation and also IFN expression following poly(I:C) transfection. Whereas FTRCA1 is associated with several pivotal signaling molecules of RIG-I-like receptor pathway, its association with TBK1 results in autophage-lysosomal degradation of TBK1, thus abrogating the downstream IFN induction. Interestingly, FTRCA1 is phosphorylated by TBK1, but this phosphorylation is not required for downregulation of TBK1 protein. Transfection assays indicate that FTRCA1 is likely an E3 ligase with the requirement of RING finger domain, and deletion of N-terminal RING domain or mutation of seven conservative sites abolishes the negative regulatory function of FTRCA1. Collectively, these results illuminate a novel finTRIM-mediated innate immune modulatory pathway, thus providing insights into species-specific regulation of fish IFN response.

Abstract
Tripartite motif (TRIM) family or RBCC proteins comprises characteristic zinc-binding domains (a RING (R), a B-box type 1 (B1) and a B-box type 2 (B2)) and coiled-coil (CC) domain followed by a C-terminus variable domain. There are about 80 different TRIM proteins in human, but more than 200 in zebrafish with several large gene expansions (ftr >70 genes; btr >30 genes; trim35 > 30 genes). Repertoires of trim genes in fish are variable across fishes, but they have been remarkably diversified independently in a number of species. In mammals, TRIM proteins are involved in antiviral immunity through an astonishing diversity of mechanisms, from direct viral restriction to modulation of immune signaling and more recently autophagy. In fish, the antiviral role of TRIM proteins remains poorly understood. In zebrafish, fish specific TRIMs so called fintrims show a signature of positive selection in the C terminus SPRY domain, reminding features of mammalian antiviral trims such as TRIM5. Expression studies show that a number of trim genes, including many fintrims, can be induced during viral infections, and may play a role in antiviral defence. Some of them trigger antiviral activity in vitro against DNA and RNA viruses, such as FTR83 that also up-regulates the expression of type I IFN in zebrafish larvae. The tissue distribution of TRIM expression suggests that they may be involved in the regionalization of antiviral immunity, providing a particular protection to sensitive areas exposed to invading pathogens.

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
Type I IFNs are a family of cytokines with antiviral, anti-proliferative and immune-modulatory functions. In this study, four type I IFNs (termed AjIFN1-4) have been cloned from the Japanese eel, Anguilla japonica. The open reading frames of AjIFN1-4 are 552, 534, 546 and 561 bp in length, encoding 183, 177, 181, and 186 amino acids (aa), respectively. Sequence comparison and phylogenetic analysis results revealed that AjIFN1 and AjIFN2 belong to group one (2C-containing) IFNs, while AjIFN3 and AjIFN4 belong to group two (4C-containing) IFNs. Syntenic comparison showed that chromosome block duplication and rearrangement events might have occurred at IFN loci in different teleost lineages. Expression analysis revealed the rapid induction of AjIFNl and AjIFN2 in response to poly I:C stimulation, while AjIFN3 and AjIFN4 were predominantly expressed at later time points. Two Mx promoter reporter assays were conducted to assess the Mx-inducing capability of AjIFN1-4. It is shown that the overexpression of AjIFN1-4 all promoted the luciferase activity of MxB reporter, but the activity of MxC reporter increased only in cells transfected with AjIFN1. Collectively, it is suggested that teleost IFNs were evolved independently in different lineages of fish and may function differently in teleost antiviral immunity.

Abstract
Dabry's sturgeon (Acipenser dabryanus), as a living fossil, is considered a critically endangered aquatic animal in China. To date, the immune system of this species remains largely unknown, with limited available sequence information. In addition, increasing incidence of bacterial pathogenic diseases has been reported. Hence, the present study aimed to characterize comprehensively transcriptome profile of the head kidney from Dabry's sturgeon infected with Aeromonas hydrophila using Illumina platform. Over 42 million high-quality reads were obtained and de novo assembled into a final set of 195240 unique transcript fragments (unigenes), with an average length of 564 bp. Approximately 41702 unigenes were annotated in the NR NCBI database. Dabry's sturgeon unigenes had the highest number of hits with 14365 (34.45%) to Lepisosteus oculatus. The 195240 unigenes were assigned to three Gene Ontology (GO) categories: biological process, cellular component, and molecular function. Among them, 27770 unigenes were clustered into 26 Eukaryotic Orthologous Group (KOG) functional categories, and 36031 unigenes were mapped to 335 known Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. After A. hydrophila administration, 1728 differentially expressed unigenes were identified, including 980 upregulated and 748 downregulated unigenes. Further KEGG enrichment analysis of these unigenes identified 16 immune-related pathways, including the Toll-like receptor signaling pathway, chemokine signaling pathway, complement and coagulation pathway, RIG-I-like receptor signaling pathway, and NOD-like receptor signaling pathway. 20 DEGs were selected and their expression patterns are largely consistent with the transcriptome profile analysis, which clearly validated the reliability of the DEGs in transcriptome analysis. This work revealed novel gene expression patterns of Dabry's sturgeon host defense and contributes to a better understanding of the immune system and defense mechanisms of Dabry's sturgeon in response to bacterial infection. The results provide valuable references for studies in sturgeons that lack complete genomic sequences, and could also be helpful for the analyzing evolution among cartilaginous and teleost fish.

FISH & SHELLFISH IMMUNOLOGY 2018; 79:42-51. [PMID: 29747011 DOI: 10.1016/j.fsi.2018.05.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Revised: 04/30/2018] [Accepted: 05/06/2018] [Indexed: 06/08/2023]
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
Ubiquitination, a post-translational modification via ubiquitin-proteasome-system, is one of the vital cellular processes involved in intracellular signaling, cell death, transcriptional control, etc. Importantly, it prevents the aggregation of non-functional, misfolded or unfolded, potentially toxic proteins to maintain cellular protein homeostasis. Ubiquitination is accomplished by the concerted action of three enzymatic steps involving E1 activating enzymes, E2 conjugating enzymes, and E3 ligases. Tripartite motif-containing (TRIM) proteins are one of the integral members of E3 ubiquitin ligases in metazoans modulating essential cellular pathways. For long, MuRFs (Muscle ring finger proteins) were the most extensively studied TRIMs for their cardiac function. Recent research advances in the field and our analysis presented here, however, demonstrated broader and ever increasing involvement of additional TRIM E3 ligases in the pathophysiology of heart. In this review, we summarize the known cardiac E3 ligases and their targets, and discuss their role and importance in cardiac proteostasis, pathophysiology and potential therapeutic implications with specific focus on TRIM E3 ligases.

Abstract
Tripartite motif-containing protein 35 (TRIM35) has been demonstrated to exert critical roles in cancer, cell death and other multiple cell processes. However, the precisely roles of TRIM35 during virus infection still remained largely unknown. In the current study, we cloned a TRIM35 gene from orange spotted grouper (EcTRIM35) and uncovered its roles in response to nodavirus infection. EcTRIM35 encoded a 456-aa protein which showed 65% and 32% identity to large yellow croaker (Larimichthys crocea) and human (Homo sapiens), respectively. Structure prediction and amino acid alignment analysis indicated that EcTRIM35 contained three conserved domains, including RING domain, B-BOX and SPRY domain. In healthy grouper, the high expression level of EcTRIM35 could be detected in liver, spleen and intestine. After infection with red-spotted grouper nervous necrosis (RGNNV) and Singapore grouper iridovirus (SGIV) in GS cells, the transcript of EcTRIM35 was significantly up-regulated with the infection time increased. Under fluorescence microscopy, the bright fluorescence aggregates were observed in EcTRIM35 transfected cells, but the fluorescence distribution was obviously altered in the EcTRIM35-ΔRING transfected cells. After incubation with RGNNV, the overexpression of EcTRIM35 in vitro significantly enhanced the viral replication, evidenced by the enhancement of cytopathic effect (CPE) severity and the up-regulation of the viral gene transcription. Moreover, the ectopic expression of EcTRIM35 significantly decreased the expression of interferon signaling molecules or effectors. Further studies elucidated that EcTRIM35 overexpression significantly weakened the MAVS-, MITA- or TBK1-induced interferon immune response, but showed no effects on MDA5-induced immune response. Thus, our results will shed new lights on the roles of fish TRIM35 in innate immune response against grouper virus infection.

Abstract
The repeated phenotypic patterns that characterize populations undergoing parallel evolution provide support for a deterministic role of adaptation by natural selection. Determining the level of parallelism also at the genetic level is thus central to our understanding of how natural selection works. Many studies have looked for repeated genomic patterns in natural populations, but work on gene expression is less common. The studies that have examined gene expression have found some support for parallelism, but those studies almost always used samples collected from the wild that potentially confounds the effects of plasticity with heritable differences. Here we use two independent pairs of lake and stream threespine stickleback (Gasterosteus aculeatus) raised in common garden conditions to assess both parallel and antiparallel (that is, similar versus different directions of lake–stream expression divergence in the two watersheds) heritable gene expression differences as measured by total RNA sequencing. We find that more genes than expected by chance show either parallel (22 genes, 0.18% of expressed genes) or antiparallel (24 genes, 0.20% of expressed genes) lake–stream expression differences. These results correspond well with previous genomic studies in stickleback ecotype pairs that found similar levels of parallelism. We suggest that parallelism might be similarly constrained at the genomic and transcriptomic levels.

Abstract
The innate antiviral response is integral in protecting the host against virus infection. Many proteins regulate these signaling pathways including ubiquitin enzymes. The ubiquitin-activating (E1), -conjugating (E2), and -ligating (E3) enzymes work together to link ubiquitin, a small protein, onto other ubiquitin molecules or target proteins to mediate various effector functions. The tripartite motif (TRIM) protein family is a group of E3 ligases implicated in the regulation of a variety of cellular functions including cell cycle progression, autophagy, and innate immunity. Many antiviral signaling pathways, including type-I interferon and NF-κB, are TRIM-regulated, thus influencing the course of infection. Additionally, several TRIMs directly restrict viral replication either through proteasome-mediated degradation of viral proteins or by interfering with different steps of the viral replication cycle. In addition, new studies suggest that TRIMs can exert their effector functions via the synthesis of unconventional polyubiquitin chains, including unanchored (non-covalently attached) polyubiquitin chains. TRIM-conferred viral inhibition has selected for viruses that encode direct and indirect TRIM antagonists. Furthermore, new evidence suggests that the same antagonists encoded by viruses may hijack TRIM proteins to directly promote virus replication. Here, we describe numerous virus–TRIM interactions and novel roles of TRIMs during virus infections.

Abstract
Tripartite motif (TRIM) proteins are receiving increased research interest because of their roles in a wide range of cellular biological processes in innate immunity. In zebrafish (Danio rerio), the functions of the finTRIM (ftr) family are unclear. In the present study, we investigated the expression pattern of ftr12, ftr51, ftr67, ftr82, ftr83, and ftr84 in zebrafish for the first time. The results showed that ftr12, ftr67, and ftr84 are maternally expressed in the oocyte and highly expressed at the early stage (0-4 hpf) of embryo (P < 0.05), suggesting their involvement in the embryonic innate defense system. The ftr82 gene was highly expressed at 8 hpf (P < 0.05), which implied that the embryos could synthesize their own immunity-related mRNAs. However, ftr51 and ftr83 were highest at 8 hpf (2.33 and 51.53 relative to β-actin respectively) and might mediate embryonic development. The expression levels of ftr12, ftr51, and ftr67 were highest in the gill, intestines, and liver, respectively. Ftr82, ftr83, and ftr84 were predominantly expressed in the kidney, suggesting that these finTRIMs might play roles in both immunity and non-immunity-related tissue compartments. Zebrafish embryonic fibroblast (ZF4) cells were infected with Grass carp reovirus (GCRV) and Spring viremia of carp virus (SVCV). During GCRV infection, the expression of ftr12 was significantly upregulated from 12 h to 24 h; and ftr51 and ftr67 increased from 3 h to 12 h. The expressions of ftr82, ftr83, and ftr84 were only upregulated at 12 h, 12 h, and 24 h, respectively. All of these genes were significantly downregulated at 48 h (P < 0.05). Challenge with SVCV upregulated the expressions of ftr12 and ftr51 at 12 h and 48 h (P < 0.05), respectively, and ftr67 reached its highest expression level at 3 h. ftr82 showed only a slight upregulation at 6 h and 48 h, and ftr83 and ftr84 were consecutively increased, reaching their highest levels at 12 h (P < 0.05). Meanwhile, ftr67 and ftr83 were significantly downregulated at 48 h (P < 0.05). Our research demonstrated that ftr12, ftr51, ftr67, ftr82, ftr83, and ftr84 probably have important roles in innate immune responses and in non-immunity-related tissues.

Abstract
The tripartite motifs (TRIMs) constitute a large family of proteins containing a Really Interesting New Gene (RING) domain, a B-box domain and coiled-coil region followed by different C-terminal domains. TRIM proteins play multiple roles in various cellular processes, including cell growth, differentiation, apoptosis and antiviral immunity. Fish novel large multigene TRIM genes (finTRIM/ftr) appear only in teleosts and play a vital role in antiviral responses. Phylogenetic analysis revealed the existence of different subsets of novel fish TRIM 14 genes (finTRIM14/ftr14), ftr51, ftr67, ftr72, ftr82, ftr83, and ftr99 in grass carp (Ctenopharyngodon idella), suggesting lineage-specific diversification events. Therefore, the number of finTRIM genes varies greatly among species. The ftr genes in grass carp, which are closely related to zebrafish and possess various evolutionary branches, have evolved faster than human TRIMs. The predicted protein domains were almost identical RING zinc finger domains, with the exception of ftr72, the B-box domain (excluding ftr67, ftr82, ftr83), and the B30.2 domain, which evolved under positive selection (with the exception of ftr67, and ftr72). The genes were predominantly expressed in the spleen, gill and head kidney. These findings indicate that the ftr genes in grass carp are involved diverse cellular processes, including innate immune responses.
