FISH & SHELLFISH IMMUNOLOGY 2023; 134:108623. [PMID: 36809843 DOI: 10.1016/j.fsi.2023.108623] [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: 11/30/2022] [Revised: 02/16/2023] [Accepted: 02/16/2023] [Indexed: 06/18/2023]
Abstract
Long noncoding RNAs (lncRNAs) play important roles in many biological processes including the immune response against virus infection. However, their roles in grass carp reovirus (GCRV) pathogenicity are largely unknown. In this study, the next-generation sequencing (NGS) technology was used to analyze the profiles of lncRNAs in GCRV-infected and mock-infected grass carp kidney (CIK) cells. Our results showed that 37 lncRNAs and 1039 mRNA transcripts exhibited differential expression in CIK cells after GCRV infection compared with the mock infection. Functional analysis through the gene ontology and Kyoto Encyclopedia of Genes and Genomes databases (KEGG) indicated that target genes of the differentially expressed lncRNAs were mainly enriched in the biological processes - biological regulation, cellular process, metabolic process and regulation of the biological process, such as MAPK signaling pathway and Notch signaling. Furthermore, we observed that the lncRNA3076 (ON693852) was markedly upregulated after the GCRV infection. In addition, silencing lncRNA3076 decreased the GCRV replication, which indicates that it might play an important role in the replication of GCRV.

A multi-target dsRNA for simultaneous inhibition of yellow head virus and white spot syndrome virus in shrimp. J Biotechnol 2020; 321:48-56.

Abstract
Outbreaks of diseases caused by yellow head virus (YHV) and white spot syndrome virus (WSSV) infection in shrimp have resulted in economic losses worldwide. DsRNA-mediated RNAi has been used to control these viruses, and the best target genes for efficient inhibition of YHV and WSSV are the protease and ribonuleotide reductase small subunit (rr2), respectively. However, one dsRNA can suppress only one virus, and therefore the production of multi-target dsRNA to effectively inhibit both YHV and WSSV is needed. In this study, plasmids pETpro-rr2_one stem and pETpro-rr2_two stems were constructed to produce two different forms of multi-target dsRNA in E. coli, which were designed specifically to both YHV protease and WSSV rr2 genes. The potency of each dsRNA in inhibiting YHV and WSSV and reducing shrimp death were investigated in L. vannamei. Shrimp were injected with the dsRNAs into the hemolymph before challenge with YHV or WSSV. The results showed that both dsRNAs could inhibit the viruses, however the one stem construct was more effective than the two stems construct when shrimp were infected with WSSV. This study establishes a potential strategy for dual inhibition of YHV and WSSV for further application in shrimp aquaculture.

Abstract
Swine enteric coronaviruses (SECoVs), including porcine epidemic diarrhea virus (PEDV), swine acute diarrhea syndrome coronavirus (SADS-CoV), and porcine deltacoronavirus (PDCoV) have emerged and been prevalent in pig populations in China for the last several years. However, current traditional inactivated and attenuated PEDV vaccines are of limited efficacy against circulating PEDV variants, and there are no commercial vaccines for prevention of PDCoV and SADS-CoV. RNA interference (RNAi) is a powerful tool in therapeutic applications to inhibit viral replication in vitro. In this study, we developed a small interfering RNA generation system that expressed two different short hairpin RNAs (shRNAs) targeting the M gene of PEDV and SADS-CoV and the N gene of PDCoV, respectively. Our results demonstrated that simultaneous expression of these specific shRNA molecules inhibited expression of PEDV M gene, SADS-CoV M gene, and PDCoV N gene RNA by 99.7%, 99.4%, and 98.8%, respectively, in infected cell cultures. In addition, shRNA molecules significantly restricted the expression of M and N protein, and impaired the replication of PEDV, SADS-CoV, and PDCoV simultaneously. Taken together, this shRNAs expression system not only is proved to be a novel approach for studying functions of various genes synchronously, but also developed to test aspects of a potential therapeutic option for treatment and prevention of multiple SECoV infections. Two potential targets of antiviral molecules for the treatment of three swine enteric coronaviruses replication are tested. The multiple-shRNA expression vector was constructed to effectively inhibit PEDV, SADS-CoV, and PDCoV. A shRNA-based multiple-resistance antiviral strategy, significantly affecting viral replication, was evaluated in vitro.

Abstract
Grass carp reovirus (GCRV) is the primary cause of grass carp haemorrhagic disease. The major catechin in green tea, (-)-epigallocatechin-3-gallate (EGCG), has been found to have anti-GCRV activity in the C. idellus kidney cell line (CIK). The aim of this study was to test the potential application of EGCG as an anti-GCRV agent in aquaculture. Here, we demonstrate that various concentrations (99%, 50% and 35%) of EGCG could inhibit GCRV infectivity. EGCG (50%) + GCRV treatment significantly reduced the number of dead fish at 1-, 2-, 3-, 4 -and 5-day post-challenge compared with the negative control (GCRV challenge without EGCG treatment). The safety of EGCG compound products on cell survival was studied using four fish cell lines; we did not detect a significant change in cell viability within 24 hours of EGCG incubation. We also evaluated toxicity and concentrations of malondialdehyde (MDA), glutathione (GSH) and lysozyme (LZM) in the grass carp, and the results showed that even a high dose of EGCG did not induce toxicity. Following EGCG compound injection, the concentration of MDA decreased and the concentration of GSH and LZM increased compared with the control groups. We also detected EGCG concentration in grass carp plasma and kidney using HPLC with electrochemical detection after intraperitoneal injection at a dose of 150 mg/kg. The concentration of EGCG in the plasma and kidney reached the highest levels (20 μg/ml and 1.5 μg/ml) about 12 hr after injection and then decreased. Overall, EGCG is a safe, effective product that could inhibit GCRV infection and improve immunoactivity in aquaculture.

Abstract
Background Grass carp (Ctenopharyngodon idella) hemorrhagic disease is caused by an acute infection with grass carp reovirus (GCRV). The frequent outbreaks of this disease have suppressed development of the grass carp farming industry. GCRV104, the representative strain of genotype III grass carp (Ctenopharyngodon idella) reovirus, belongs to the Spinareovirinae subfamily and serves as a model for studying the strain of GCRV which encodes an outer-fiber protein. There is no commercially available vaccine for this genotype of GCRV. Therefore, the discovery of new inhibitors for genotype III of GCRV will be clinically beneficial. In addition, the mechanism of GCRV with fiber entry into cells remains poorly understood. Methods Viral entry was determined by a combination of specific pharmacological inhibitors, transmission electron microscopy, and real-time quantitative PCR. Results Our results demonstrate that both GCRV-JX01 (genotype I) and GCRV104 (genotype III) of GCRV propagated in the grass carp kidney cell line (CIK) with a typical cytopathic effect (CPE). However, GCRV104 replicated slower than GCRV-JX01 in CIK cells. The titer of GCRV-JX01 was 1000 times higher than GCRV104 at 24 h post-infection. We reveal that ammonium chloride, dynasore, pistop2, chlorpromazine, and rottlerin inhibit viral entrance and infection, but not nystatin, methyl-β-cyclodextrin, IPA-3, amiloride, bafilomycin A1, nocodazole, and latrunculin B. Furthermore, GCRV104 and GCRV-JX01 infection of CIK cells depended on dynamin and the acidification of the endosome. This was evident by the significant inhibition following prophylactic treatment with the lysosomotropic drug ammonium chloride or dynasore. Conclusions Taken together, our data have suggested that GCRV104 enters CIK cells through clathrin-mediated endocytosis in a pH-dependent manner. We also suggest that dynamin is critical for efficient viral entry. Additionally, the phosphatidylinositol 3-kinase inhibitor wortmannin and the protein kinase C inhibitor rottlerin block GCRV104 cell entry and replication.

Abstract
The hemorrhagic disease of grass carp (Ctenopharyngodon idellus) induced by grass carp reovirus (GCRV) leads to huge economic losses in China and currently, there are no effective methods available for prevention and treatment. The various GCRV genotypes may be one of the major obstacles in the pursuit of an effective antiviral treatment. In this study, we exploited CRISPR/Cas9 gene editing to specifically knockout the DNA sequence of the grass carp Junctional Adhesion Molecule-A (gcJAM-A) and evaluated in vitro resistance against various GCRV genotypes. Our results show that CRISPR/Cas9 effectively knocked out gcJAM-A and reduced GCRV infection for two different genotypes in permissive grass carp kidney cells (CIK), as evidenced by suppressed cytopathic effect (CPE) and GCRV progeny production in infected cells. In addition, with ectopic expression of gcJAM-A in cells, non-permissive cells derived from Chinese giant salamander (Andrias davidianus) muscle (GSM) could be highly infected by both GCRV-JX0901 and Hubei grass carp disease reovirus (HGDRV) strains that have different genotypes. Taken together, the results demonstrate that gcJAM-A is necessary for GCRV infection, implying a potential approach for viral control in aquaculture.

Abstract
Reoviruses are potential anticancer agents due to their ability to induce cell death in tumor cells. Grass carp reovirus (GCRV) is one of the best characterized models on reovirus pathogenesis in vitro. However, there is little known about how SUMOylation affects reovirus pathogenesis. The SUMO conjugating enzyme 9 (Ubc9) determines the targets of SUMOylation. Here, the protein interactions between reovirus outer fiber proteins, specifically GCRV-104 VP55, and Ubc9 were probed using a yeast two-hybrid system. The N-terminal coiled-coil domain of VP55, containing a single lysine residue, was responsible for the interaction between VP55 and Ubc9 in yeast. In solid phase binding assays, a single amino acid mutation (K87R) prevented Ubc9 from binding to VP55. Overexpression of Ubc9 enhanced GCRV-104 infection efficiency, and knockdown of Ubc9 in CIK cells inhibited viral replication, which suggested that Ubc9 was a proviral factor. Furthermore, Ubc9 was shown to bind outer fiber proteins from type II GCRV, avian reovirus and mammalian reovirus in yeast. To our knowledge, this is the first study to show that Ubc9 binds to reovirus outer-fiber proteins and likely contributes to efficient orthoreovirus replication. These results suggest that SUMOylation modifications could be targeted to improve the therapeutic efficacy of oncolytic reovirus.

Abstract
Previous report demonstrated that grass carp reovirus (GCRV) infection resulted in unlinking cellular stress granule formation from aggregation of grass carp Ctenopharyngodon idella TIA1 (CiTIA1). Here, we provided evidence to show that CiTIA1 bound to synthesized ssRNA and dsRNA in vitro. Both GST-pull down assay and RNA immunoprecipitation analysis confirmed the association between GCRV-specific RNA and GST-tagged CiTIA1 in C. idella kidney (CIK) cells. Furthermore, CiTIA1 was shown to protect dsRNA of virus-origin from degradation in CIK cells through Northern blot analysis. Finally, transient overexpression of CiTIA1 enhanced the replication efficiency of GCRV in CIK cells. Taken together, our results suggested that cellular CiTIA1 might facilitate GCRV replication through sequestrating and protecting viral RNA from degradation.

Abstract
Human tumor necrosis factor receptor-associated protein 1 (Trap1) is a mitochondrial protein identical to heat shock protein 75 (HSP75) that plays an important role in protecting cells from oxidative stress and apoptosis. In this study, grass carp (Ctenopharyngodon idella) tumor necrosis factor receptor-associated protein 1 (designated as CiTrap1) was identified through two-dimensional electrophoresis (2-DE) analysis and its pattern of expression was investigated in grass carp kidney (CIK) cells infected with grass carp reovirus (GCRV). The full length cDNA of CiTrap1 contained an opening reading frame of 2157 bp that encoded a peptide of 718 amino acids. Phylogenetic analyses indicated that the CiTrap1 shared 87% identity with its homologue from zebrafish (Danio rerio). The transcriptional level of CiTrap1 in CIK cells was upregulated post virus infection as well as poly (I: C) stimulation. Following virus infection, grass carp PTEN-induced putative kinase 1 (PINK1) and Sorcin, whose coding proteins interact with Trap1 in human, were simultaneously upregulated with CiTrap1. Typical characteristics of apoptosis were observed in CIK cells infected with GCRV by DAPI staining, DNA ladder electrophoresis, TUNEL assay and Annexin Ⅴ labeling. RNAi-mediated silencing of CiTrap1 in CIK cells resulted in the increased rate of virus-induced apoptotic cells. The results of this study suggest that CiTrap1 is involved in the host's innate immune response to viral infection possibly through protecting infected cells from apoptosis.
