[PMID: 36989948 DOI: 10.1016/j.ecoenv.2023.114825] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 03/18/2023] [Accepted: 03/22/2023] [Indexed: 06/19/2023]
Abstract
Intestinal inflammation is a protective response that is implicated in bacterial enteritis triggered by gastrointestinal infection. The immune mechanisms elicited in teleost against the infection of Aeromonas veronii are largely unknown. In this study, we performed a de novo northern snakehead (Channa argus) transcriptome assembly using Illumina sequencing platform. On this basis we performed a comparative transcriptomic analysis of northern snakehead intestine from A. veronii-challenge and phosphate buffer solution (PBS)-challenge fish, and 2076 genes were up-regulated and 1598 genes were down-regulated in the intestines infected with A. veronii. The Gene Ontology (GO) enrichment analysis indicated that the differentially expressed genes (DEGs) were enriched to 27, 21 and 20 GO terms in biological process, cellular component, and molecular function, respectively. A Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that 420 DEGs were involved in 194 pathways. Moreover, 33 DEGs were selected for quantitative real-time PCR analysis to validate the RNA-seq data. The results reflected the consistency of the expression levels between qRT-PCR and RNA-seq data. In addition, a time-course analysis of the mRNA expression of 33 immune-related genes further indicated that the intestinal inflammation to A. veronii infection simultaneously regulated gene expression alterations. The present study provides transcriptome data of the teleost intestine, allowing us to understand the mechanisms of intestinal inflammation triggered by bacterial pathogens. DATA AVAILABILITY STATEMENT: All data supporting the findings of this study are available within the article and Supplementary files. The RNA-seq raw sequence data are available in NCBI short read archive (SRA) database under accession number PRJNA615958.

Abstract
Echinacea purpurea (Linn.) Moench (EP) is a globally popular herbal medicine, which showed effects on growth promotion, antioxidant and immunomodulatory activities in fish culture world widely. However, there are few studies about the effects on miRNAs by EP in fish. The hybrid snakehead fish (Channa maculate♀ × Channa argus ♂) was new important economic specie of freshwater aquaculture in China with high market value and demand while there were only a few reports about its miRNAs. To overview immune-related miRNAs of the hybrid snakehead fish and to further understand the immune regulating mechanism of EP, we herein constructed and analyzed three small RNA libraries of immune tissues including liver, spleen and head kidney of the fish with or without EP treatment via Illumina high-throughput sequencing technology. Results showed that EP can affect the immune activities of fish by the miRNA-regulated ways. Totally, 67 (47 up and 20 down) miRNAs in liver, 138 (55 up and 83 down) miRNAs in spleen, and 251 (15 up and 236 down) miRNAs in spleen were detected, as well as 30, 60, 139 kinds of immune-related miRNAs belonging to 22, 35 and 66 families of the three tissues respectively. The expressions of 8 immune-related miRNA family members were found in all the three tissues, including miR-10, miR-133, miR-22 and etc. Some miRNAs have been identified involved in the innate and adaptive immune responses, such as the miR-125, miR-138, and miR-181 family. Ten miRNA families with antioxidant target genes were also discovered, including miR-125, miR-1306, and miR-138, etc. Results from Gene Ontology (GO) and KEGG pathway analysis further confirmed there are a majority immune response targets of the miRNAs involved in the EP treatment process. Our study deepened understanding roles of miRNAs in fish immune system and provides new ideas for the study of immune mechanism of EP.

Abstract
Porcine circovirus type 2 (PCV2) is the causative agent of PCV2-associated disease, which causes a relevant economic impact on the global swine industry. Accumulating data have indicated host microRNAs play essential roles in numerous virus replication of pigs, while their roles in PCV2 replication remain unclear. Herein, we demonstrated that PCV2 infection downregulated the expression of miR-214-5p in PK15 cells, and miR-214-5p promoted PCV2 replication. C1q/tumor necrosis factor-related protein 1 (C1QTNF1) was then identified as a target gene of miR-214-5p, and C1QTNF1 suppressed PCV2 replication. Interestingly, miR-214-5p/C1QTNF1 axis negatively regulated AKT/mTOR signaling, and then enhanced PCV2 replication through promoting autophagy in PK15 cells. Collectively, our findings provide insight into the mechanism of PCV2 replication and highlight miR-214-5p and C1QTNF1 as potential novel targets for the treatment of PCV2 infection.

Abstract
MicroRNAs (miRNAs) are a class of highly conserved, endogenous non-coding single-stranded small RNA molecules with a length of 18-25 nucleotides. MiRNAs can negatively regulate the target gene through complementary pairing with the mRNA. It has been more than 20 years since the discovery of miRNA molecules, and many achievements have been made in fish research. This paper reviews the research progress in the regulation of fish nutrition and immunity by miRNAs in recent years. MiRNAs regulate the synthesis of long-chain polyunsaturated fatty acids, and are involved in the metabolism of glucose, lipids, as well as cholesterol in fish. Moreover, miRNAs play various roles in antibacterial and antiviral immunity of fish. They can promote the immune response of fish, but may also participate in the immune escape mechanism of bacteria or viruses. One important aspect of miRNAs regulation on fish immunity is mediated by targeting pattern recognition receptors and downstream signaling factors. Together, current results indicate that miRNAs are widely involved in the complex regulatory network of fish. Further studies on fish miRNAs may deepen our understanding of the regulatory network of fish nutrition and immunity, and have the potential to promote the development of microRNA-based products and detection reagents that can be applied in aquaculture industry.

Abstract
MicroRNAs are a class of evolutionary conserved non-coding small RNAs that play key regulatory roles at the post-transcriptional level. In recent years, studies have shown that miR-214 plays an important role in regulating several biological processes such as cell proliferation and differentiation, tumorigenesis, inflammation and immunity, and it has become a hotspot in the miRNA field. In this review, the regulatory functions of miR-214 in the proliferation, differentiation and functional activities of immune-related cells, such as dendritic cells, T cells and NK cells, were briefly reviewed. Also, the mechanisms of miR-214 involved in tumor immunity, inflammatory regulation and antivirus were discussed. Finally, the value and application prospects of miR-214 as a molecular marker in inflammation and tumor related diseases were analyzed briefly. We hope it can provide reference for further study on the mechanism and application of miR-214.

Abstract
Leader RNA, a kind of virus-derived small noncoding RNA, has been proposed to play an important role in regulating virus replication, but the underlying mechanism remains elusive. In this study, snakehead vesiculovirus (SHVV), a kind of fish rhabdovirus causing high mortality to the cultured snakehead fish in China, was used to unveil the molecular function of leader RNA. High-throughput small RNA sequencing of SHVV-infected cells showed that SHVV produced two groups of leader RNAs (named legroup1 and legroup2) during infection. Overexpression and knockout experiments reveal that legroup1, but not legroup2, affects SHVV replication. Mechanistically, legroup1-mediated regulation of SHVV replication was associated with its interaction with the viral nucleoprotein (N). Moreover, the nucleotides 6-10 of legroup1 were identified as the critical region for its interaction with the N protein, and the amino acids 1-45 of N protein were proved to confer its interaction with the legroup1. Taken together, we identified two groups of SHVV leader RNAs and revealed a role in virus replication for one of the two types of leader RNAs. This study will help understand the role of leader RNA in regulating the replication of negative-stranded RNA viruses.

Snakehead vesiculovirus (SHVV) infection alters striped snakehead (Ophicephalus striatus) cells (SSN-1) glutamine metabolism and apoptosis pathways. FISH & SHELLFISH IMMUNOLOGY 2020; 102:36-46. [PMID: 32289513 DOI: 10.1016/j.fsi.2020.04.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 04/06/2020] [Accepted: 04/07/2020] [Indexed: 06/11/2023]
Abstract
Snakehead vesiculovirus (SHVV) causes enormous economic losses in snakehead fish (Ophicephalus striatus) culture. Understanding replication mechanisms of virus is considerable significance in preventing and treating viral disease. In our previous studies, we have reported that glutamine starvation could significant inhibit the replication of SHVV. Furthermore, we also showed that SHVV infection could cause apoptosis of striped snakehead fish cells (SSN-1). However, the underlying mechanisms remain enigmatic. To decipher the relationships among the viral infection, glutamine starvation and apoptosis, SSN-1 cells transcriptomic profilings of SSN-1 cells infected with or without SHVV under glutamine deprived condition were analyzed. RNA-seq was used to identify differentially expressed genes (DEGs). Our data revealed that 1215 up-regulated and 226 down-regulated genes at 24 h post-infection were involved in MAPK, apoptosis, RIG-1-like and toll-like receptors pathways and glutamine metabolism. Subsequently, DEGs of glutamine metabolism and apoptosis pathways were selected to validate the sequencing data by quantitative real-time PCR (qRT-PCR). The expression patterns of both transcriptomic data and qRT-PCR were consistent. We observed that lack of glutamine alone could cause mild cellular apoptosis. However, lack of glutamine together with SHVV infection could synergistically enhance cellular apoptosis. When the cells were cultured in complete medium with glutamine, overexpression of glutaminase (GLS), an essential enzyme for glutamine metabolism, could significantly enhance the SHVV replication. While, SHVV replication was decreased in cells when GLS was knocked down by specific siRNA, indicating that glutamine metabolism was essential for viral replication. Furthermore, the expression level of caspase-3 and Bax was significantly decreased in SHVV infected cells with GLS overexpression. By contrast, they were significantly increased in SHVV infected cells with GLS silence by SiRNA, indicating that SHVV infection activated the Bax and caspase-3 pathways to induce apoptosis independent of glutamine. Our results reveal that SHVV replication and starvation of glutamine could synergistically promote the cellular apoptosis, which will pave a new way for developing strategies against the vial infection.

Abstract
We investigated differential gene expression in Tilapia infected with the Tilapia Lake virus (TiLV).We used high-throughput sequencing to identify mRNAs and miRNAs involved in TiLV infection progression We identified 25,359 differentially expressed genes that included 863 new genes. We identified 1770, 4142 and 4947 differently expressed genes comparing non-infected controls with 24 and 120 h infections and between the infected groups, respectively. These genes were enriched to 291 GO terms and 62 KEGG pathways and included immune system progress and virion genes. High-throughput miRNA sequencing identified 316 conserved miRNAs, 525 known miRNAs and 592 novel miRNAs. Furthermore, 138, 198 and 153 differently expressed miRNAs were found between the 3 groups listed above, respectively. Target prediction revealed numerous genes including erythropoietin isoform X2, double-stranded RNA-specific adenosine deaminase isoform X1, bone morphogenetic protein 4 and tapasin-related protein that are involved in immune responsiveness. Moreover, these target genes overlapped with differentially expressed mRNAs obtained from RNA-seq. These target genes were significantly enriched to GO terms and KEGG pathways including immune system progress, virion and Wnt signaling pathways. Expression patterns of differentially expressed mRNA and miRNAs were validated in 20 mRNA and 19 miRNAs by qRT-PCR. We also were able to construct a miRNA-mRNA target network that can further understand the molecular mechanisms on the pathogenesis of TiLV and guide future research in developing effective agents and strategies to combat TiLV infections in Tilapia.

Abstract
Emerging evidence has indicated that colony-stimulating factor-1 (CSF1) modulates neuroinflammation in the central nervous system and the development of neuropathic pain, while the underlying mechanism remains unknown. Here, we identified the increased expression of CSF1 derived from activated astrocytes in the ipsilateral dorsal horn in rats with spinal nerve ligation (SNL). Suppression of CSF1 expression alleviated neuroinflammation, neuronal hyperexcitability, and glutamatergic receptor subunit upregulation in the dorsal horn and improved SNL-induced pain behavior. We also found reduced miR-214-3p expression in the ipsilateral dorsal horn following an SNL procedure; miR-214-3p directly bound to the 3'-UTR of CSF1 mRNA and negatively regulated CSF1 expression. Intrathecal delivery of miR-214-3p mimic reversed the enhanced expression of CSF1 and astrocyte overactivity and alleviated the IL-6 upregulation and pain behavior induced by SNL. Moreover, suppression of spinal miR-214-3p increased astrocyte reactivity, promoted CSF1 and IL-6 production, and induced pain hypersensitivity in naive animals. Furthermore, SNL induced the expression of DNA methyltransferase 3a (DNMT3a) that was associated with the hypermethylation of the miR-214-3p promoter, leading to reduced miR-214-3p expression in the model rodents. Treatment with the DNMT inhibitor zebularine significantly reduced cytosine methylation in the miR-214-3p promoter; this reduced methylation consequently increased the expression of miR-214-3p and decreased the content of CSF1 in the ipsilateral dorsal horn and, further, attenuated IL-6 production and pain behavior in rats with SNL. Together, our data indicate that the DNMT3a-mediated epigenetic suppression of miR-214-3p enhanced CSF1 production in astrocytes, which subsequently induced neuroinflammation and pain behavior in SNL model rats.

FISH & SHELLFISH IMMUNOLOGY 2020; 96:53-61. [PMID: 31801694 DOI: 10.1016/j.fsi.2019.11.070] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 11/18/2019] [Accepted: 11/30/2019] [Indexed: 06/10/2023]
Abstract
Target of rapamycin (TOR) is an atypical of Ser/Thr protein kinase that plays an important role in many aspects such as cell growth, reproduction, differentiation, cell cycle regulation, autophagy and apoptosis. However, little information is known about the enzyme in crustaceans. Here, a novel TOR was identified from shrimp Penaeus vannamei (PvTOR) and its biological functions were investigated in response low temperature stress. The PvTOR gene encoded a polypeptide of 2464 amino acids with an estimated molecular mass of 279.4 kD and a predicted isoelectronic point (pI) of 7.30. Phylogenetic analysis revealed that PvTOR shared high similarity with other known species. PvTOR mRNA was detected in all the tested tissues and highest transcription in muscle and hepatopancreas. PvTOR transcriptional level was up-regulated significantly at 1.5 h and 3 h, and down-regulated at 12 h and 24 h after low temperature stress. TEM and autophagy indicator system GFP-PvLC3 suggested that low temperature induced autophagy generation. ROS, Ca2+ concentration and apoptosis rate were increased significantly in TOR-knockdown shrimp after low temperature stress. The autophagy associated gene ATG8II/I, PvBeclin-1, PvATG14, apoptosis gene PvPARP, Pvcasp-3, PvBAX and Pvp53 transcripts, and casp-3/8 activity in hemocyte were increased significantly in TOR-knockdown group shrimp at 3 h after low temperature stress. Additionally, THC counts of TOR-knockdown group were significantly higher than the dsGFP group. In summary, these results suggested that PvTOR plays an important role in the adaptation mechanisms of shrimp at low temperature by regulating autophagy and apoptosis.
