[PMID: 36924912 DOI: 10.1016/j.fsi.2023.108692] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 03/11/2023] [Accepted: 03/13/2023] [Indexed: 06/18/2023]
Abstract
Non-O1 Vibrio cholerae, a member of the Vibrio family, could cause gastrointestinal infection of Macrobrachium rosenbergii and result in significant economic losses. However, few studies on microRNA immunity related to non-O1 V. cholerae infection of M. rosenbergii. The aim of this study was to elucidate the mechanism of miRNA in the potential immune response of M. rosenbergii. to non-O1 V. cholerae MSVC-GY01 infection by transcriptome sequencing. Following quality screening, the control group received 10, 616, 712 clean reads, whereas the infected group received 9,727,616. The miRNA sequences in the two samples are extremely consistent and have a length of roughly 23 nt. In all, 871 known miRNAs were discovered, with 279 differentially expressed miRNAs (DEMs). Meanwhile, 62 novel miRNAs were predicted, including 43 DEMs. In order to understand the immune-related biological functions of DEMs, target genes were predicted. Pathway function annotation analysis showed that non-O1 V. cholerae affected the NOD-like receptor signaling pathway, RIG-I-like receptor signaling pathway, and Toll-like receptor signaling pathway, suggesting that miRNAs in the hepatopancreas play a key role in immune responses to pattern recognition receptors. Twelve DEMs were randomly selected for Quantitative Real-time PCR (qRT-PCR). Overall, the expression trends of qRT-PCR were consistent with the sequencing results. These findings corroborate the immunomodulatory function of miRNA in M. rosenbergii against non-O1 V. cholerae infection and provide guidance for the prevention and treatment of related illnesses.

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
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
The genome could be considered as raw data expressed in proteins and various types of noncoding RNAs (ncRNAs). However, a large portion of the genome is dedicated to ncRNAs, which in turn represent a considerable amount of the transcriptome. ncRNAs are modulated on levels of type and amount whenever any physiological process occurs or as a response to external modulators. ncRNAs, typically forming complexes with other partners, are key molecules that influence diverse cellular processes. Based on the knowledge of mammalian biology, ncRNAs are known to regulate and control diverse trafficking pathways and cellular activities. Long noncoding RNAs (lncRNAs) notably have diverse and more regulatory roles than microRNAs. Expanding these studies on fish has derived the same conclusion with relevance to other species, including invertebrates, explored the potentials to harness such types of RNA to further understand the biology of such organisms, and opened gates for applying recent technologies, such as RNA interference and delivering micromolecules as microRNAs to living cells and possibly to target organs. These technologies should improve aquaculture productivity and fish health, as well as help understand fish biology.

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.

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
Despite the lack of an inducible heat shock response (HSR), the Antarctic notothenioid fish, Trematomus bernacchii, has retained a level of physiological plasticity that can at least partially compensate for the effects of acute heat stress. Over the last decade, both physiological and transcriptomic studies have signaled these fish can mitigate the effects of acute heat stress by employing other aspects of the cellular stress response (CSR) that help confer thermotolerance as well as drive homeostatic mechanisms during long-term thermal acclimations. However, the regulatory mechanisms that determine temperature-induced changes in gene expression remain largely unexplored in this species. Therefore, this study utilized next generation sequencing coupled with an in silico approach to explore the regulatory role of microRNAs in governing the transcriptomic level response observed in this Antarctic notothenioid with respect to the CSR. Using RNAseq, we characterized the expression of 125 distinct miRNA orthologues in T. bernacchii gill tissue. Additionally, we identified 12 miRNAs that appear to be thermally responsive based on differential expression (DE) analyses performed between fish acclimated to control (-1.5 °C) and an acute heat stress (+4 °C). We further characterized the functional role of these DE miRNAs using bioinformatics pipelines to identify putative gene targets of the DE miRNAs and subsequent gene set enrichment analyses, which together suggest these miRNAs are involved in regulating diverse aspects of the CSR in T. bernacchii.

Abstract
MicroRNAs are non-coding RNAs, which widely participate in biological processes. In recent years, Siniperca chuatsi rhabdovirus (SCRV) has caused mass mortality in Chinese perch (Siniperca chuatsi). To identify specific miRNAs involved in SCRV infection, deep sequencing of microRNA on Chinese perch brain cell line (CPB) with or without SCRV infection were performed at 6 and 12 h post of infection (hpi). Totally 382 miRNAs were identified, including 217 known miRNA aligned with zebrafish miRNAs and 165 novel miRNAs by MiRDeep2 program. Of which 15 and 35 differentially-expressed miRNAs were determined respectively to 6 and 12 hpi. Nine miRNAs were selected randomly from the differentially-expressed miRNAs and validated by quantitative real-time PCR (qRT-PCR). These results were consistent with the microRNA sequencing results. Besides, target genes of 98 differentially-expressed miRNAs were predicted. Three of miRNAs (miR-122, miR-214, miR-135a) were selected, and its effects were analyzed in CPC cells transfected with appropriate miRNA mimics/inhibitors to evaluate its regulation effects by qRT-PCR and western blot. The results demonstrated that miR-214 inhibited the replication of SCRV, while miR-122 promoted the replication of SCRV and there was no correlation between the miR-135a and SCRV replication. These results will pave a new way for the development of effective strategies against the SCRV infection.

Abstract
Non-coding RNAs (ncRNAs) are functional RNA molecules that are transcribed from DNA but not translated into proteins. ncRNAs function as key regulators of gene expression and chromatin modification. Recently, the functional role of ncRNAs in teleost fish has been extensively studied. Teleost fish are a highly diverse group among the vertebrate lineage. Fish are also important in terms of aquatic ecosystem, food production and human life, being the source of animal proteins worldwide and models of biomedical research. However, teleost fish always suffer from the invasion of infectious pathogens including viruses and bacteria, which has resulted in a tremendous economic loss to the fishing industry worldwide. Emerging evidence suggests that ncRNAs, especially miRNAs and lncRNAs, may serve as important regulators in cytokine and chemokine signaling, antigen presentation, complement and coagulation cascades, and T cell response in teleost fish. In this review, we summarize current knowledge and understanding of the roles of both miRNAs and lncRNAs in immune regulation in teleost fish. Molecular mechanism insights into the function of ncRNAs in fish immune response may contribute to the development of potential biomarkers and therapeutic targets for the prevention and treatment of fish diseases.

Abstract
Infectious salmon anemia virus (ISAV) is the causative agent of infectious salmon anemia (ISA), a relatively novel disease primarily affecting farmed salmon species, primarily in Salmo salar specimens, causing severe outbreaks in most producer countries. Although ISAV has been extensively studied at the molecular level, not much is known about the host/cell interaction at the small RNA level. MicroRNAs (miRNAs) are small, non-coding RNA that regulate mRNA expression at the post-transcriptional level. In recent years, the putative role of these molecules in host-pathogen interactions has drawn particular attention because of their pivotal involvement as regulatory elements in a number of eukaryotic organisms. Given the importance of the salmon industry in Chile, a deep understanding of the interaction between ISAV and its hosts is of importance. In the present work, we studied the kinetic expression of selected miRNAs during ISAV infection, both in vitro and in vivo. Based on initial experimental data derived from a small RNA-Seq analysis, a group of miRNAs that were differentially expressed in infected cells were selected for analysis. As a result, two miRNAs, miR-462a-5p and miR-125 b-5p, showed increased and decreased expression, respectively, during ISAV infection.

Abstract
The innate immune system is the first line defense mechanism that recognizes, responds to, controls or eliminates invading pathogens. Toll-like receptors (TLRs) are a critical family of pattern recognition receptors (PRRs) tightly regulated by complex mechanisms involving many molecules to ensure a beneficial outcome in response to foreign invaders. MicroRNAs (miRNAs), a transcriptional and posttranscriptional regulator family in a wide range of biological processes, have been identified as new molecules related to the regulation of TLR-signaling pathways in immune responses. To date, at least 22 TLR types have been identified in more than a dozen different fish species. However, the functions and underlying mechanisms of miRNAs in the regulation of inflammatory responses related to the TLR-signaling pathway in fish is lacking. In this review, we summarize the regulation of miRNA expression profiles in the presence of TLR ligands or pathogen infections in teleost fish. We focus on the effects of miRNAs in regulating TLR-signaling pathways by targeting multiple molecules, including TLRs themselves, TLR-associated signaling proteins, and TLR-induced cytokines. An understanding of the relationship between the TLR-signaling pathways and miRNAs may provide new insights for drug intervention to manipulate immune responses in fish.

MicroRNA miR-214 Inhibits Snakehead Vesiculovirus Replication by Promoting IFN-α Expression via Targeting Host Adenosine 5'-Monophosphate-Activated Protein Kinase. Front Immunol 2017; 8:1775.

Abstract
Background Snakehead vesiculovirus (SHVV), a new rhabdovirus isolated from diseased hybrid snakehead, has emerged as an important pathogen during the past few years in China with great economical losses in snakehead fish cultures. However, little is known about the mechanism of its pathogenicity. MicroRNAs are small noncoding RNAs that posttranscriptionally modulate gene expression and have been indicated to regulate almost all cellular processes. Our previous study has revealed that miR-214 was downregulated upon SHVV infection. Results The overexpression of miR-214 in striped snakehead (SSN-1) cells inhibited SHVV replication and promoted IFN-α expression, while miR-214 inhibitor facilitated SHVV replication and reduced IFN-α expression. These findings suggested that miR-214 negatively regulated SHVV replication probably through positively regulating IFN-α expression. Further investigation revealed that adenosine 5′-monophosphate-activated protein kinase (AMPK) was a target gene of miR-214. Knockdown of AMPK by siRNA inhibited SHVV replication and promoted IFN-α expression, suggesting that cellular AMPK positively regulated SHVV replication and negatively regulated IFN-α expression. Moreover, we found that siAMPK-mediated inhibition of SHVV replication could be partially restored by miR-214 inhibitor, indicating that miR-214 inhibited SHVV replication at least partially via targeting AMPK. Conclusion The findings of this study complemented our early study, and provide insights for the mechanism of SHVV pathogenicity. SHVV infection downregulated miR-214, and in turn, the downregulated miR-214 increased the expression of its target gene AMPK, which promoted SHVV replication via reducing IFN-α expression. It can therefore assume that cellular circumstance with low level of miR-214 is beneficial for SHVV replication and that SHVV evades host antiviral innate immunity through decreasing IFN-α expression via regulating cellular miR-214 expression.

Abstract
MicroRNAs (miRNAs) have been identified as important post transcriptional regulators of gene expression. In higher vertebrates, a subset of miRNAs has been identified as important regulators of a number of key genes in immune system gene networks, and this paper review recent studies on miRNAs associated with immune response in teleost fish. Challenge studies conducted in several species have identified differently expressed miRNAs associated with viral or bacterial infection. The results from these studies point out several miRNAs that are likely to have evolutionary conserved functions that are related to immune response in teleost fish. Changed expression levels of mature miRNAs from the five miRNA genes miRNA-462, miRNA-731, miRNA-146, miRNA-181 and miRNA-223 are observed following viral as well as bacterial infection in several teleost fish. Furthermore, significant changes in expression of mature miRNAs from the five genes miRNA-21, miRNA-155, miRNA-1388, miRNA-99 and miRNA-100 are observed in multiple studies of virus infected fish while changes in expression of mature miRNA from the three genes miRNA-122, miRNA-192 and miRNA-451 are observed in several studies of fish with bacterial infections. Interestingly, some of these genes are not present in higher vertebrates. The function of the evolutionary conserved miRNAs responding to infection depends on the target gene(s) they regulate. A few target genes have been identified while a large number of target genes have been predicted by in silico analysis. The results suggest that many of the targets are genes from the host's immune response gene networks. We propose a model with expected temporal changes in miRNA expression if they target immune response activators/effector genes or immune response inhibitors, respectively. The best way to understand the function of a miRNA is to identify its target gene(s), but as the amount of genome resources for teleost fish is limited, with less well characterized genomes and transcriptomes, identifying the true target genes of the miRNAs associated with the immune response is a challenge. Identifying such target genes by applying new methods and approaches will likely be the next important step to understand the function of the miRNAs associated with immune response in teleost fish.

Abstract
High-throughput sequencing was applied to analyze the effects of toxic Microcystis aeruginosa on the silver carp Hypophthalmichthys molitrix. Silver carps were exposed to two cyanobacteria species (toxic and non-toxic) for RNA-seq and miRNA-seq analysis. RNA-seq revealed that the liver tissue contained 105,379 unigenes. Of these genes, 143 were significantly differentiated, 82 were markedly up-regulated, and 61 were remarkably down-regulated. GO term enrichment analysis indicated that 35 of the 154 enriched GO terms were significantly enriched. KEGG pathway enrichment analysis demonstrated that 17 of the 118 enriched KEGG pathways were significantly enriched. A considerable number of disease/immune-associated GO terms and significantly enriched KEGG pathways were also observed. The sequence length determined by miRNA-seq was mainly distributed in 20-23 bp and composed of 882,620 unique small RNAs, and 53% of these RNAs were annotated to miRNAs. As confirmed, 272 known miRNAs were differentially expressed, 453 novel miRNAs were predicted, 112 miRNAs were well matched with 7,623 target genes, and 203 novel miRNAs were matched with 15,453 target genes. qPCR also indicated that Steap4, Cyp7a1, CABZ01088134.1, and PPP1R3G were significantly differentially expressed and might play major roles in the toxic, detoxifying, and antitoxic mechanisms of microcystin in fish.

Abstract
Snakehead vesiculovirus (SHVV) has caused mass mortality to cultured snakehead fish in China, resulting in enormous economic losses in snakehead fish culture. In this report, the whole genome of SHVV was sequenced. Interestingly, it shared more than 94% nucleotide sequence identity with Monopterus albus rhabdovirus (MoARV), which has caused great economic loss to cultured rice field eel (Monopterus albus). Therefore, the concern of cross-species infection of these viruses prompted us to investigate the susceptibility of rice field eel to SHVV infection. The results showed that rice field eel was susceptible to SHVV in both intracoelomical injection and immersion routes. Severe hemorrhage was observed on the skin and visceral organs of SHVV-infected rice field eels. Histopathological examination showed vacuoles in the tissues of infected liver, kidney and heart. Viral RNA or protein was detected in the tissues of infected fish by reverse transcription polymerization chain reaction (RT-PCR), in situ hybridization (ISH), or immunohistochemistry assay (IHC). Investigation of the epidemic of vesiculovirus in rice field eel as well as other co-cultured fish is invaluable for the prevention of vesiculovirus infection.

Abstract
Snakeheadvesiculovirus (SHVV), a new member of the family Rhabdoviridae, has caused enormous economic losses in snakehead fish culture during the past years in China; however, little is known about the molecular mechanisms of its pathogenicity. MicroRNAs (miRNAs) are small non-coding RNAs that play important roles in virus infection. In this study, we identified that SHVV infection downregulated miR-214 in striped snakehead (SSN-1) cells in a time- and dose-dependent manner. Notably, transfecting SSN-1 cells with miR-214 mimic significantly inhibitedSHVV replication, whereas miR-214 inhibitor promoted it, suggesting that miR-214 acted as a negative regulator of SHVV replication. Our study further demonstrated that N and P of SHVV were the target genes of miR-214. Over-expression of P, but not N, inhibited IFN-α production in SHVV-infected cells, which could be restored by over-expression of miR-214. Taken together, these results suggest that miR-214 is downregulated during SHVV infection, and the downregulated miR-214 in turn increased N and P expression and decreased IFN-α production, thus facilitating SHVV replication. This study provides a better understanding of the molecular mechanisms on the pathogenesis of SHVV and a potential antiviral strategy against SHVV infection.

Abstract
Nervous necrosis virus (NNV), one of the most prevalent fish pathogens, has caused fatal disease of viral nervous necrosis (VNN) in many marine and freshwater fishes, and resulted in heavy economic losses in aquaculture industry worldwide. However, the molecular mechanisms underlying the pathogenicity of NNV remain elusive. In this study, the expression profiles of microRNA (miRNA) were investigated in grouper fin (GF-1) cells infected with red-spotted grouper nervous necrosis virus (RGNNV) via deep sequencing technique. The results showed that a total of 220 miRNAs were identified by aligning the small RNA sequences with the miRNA database of zebrafish, and 18 novel miRNAs were predicted using miRDeep2 software. Compared with the non-infected groups, 51 and 16 differentially expressed miRNAs (DE-miRNAs) were identified in the samples infected with RGNNV at 3 and 24 h, respectively. Six DE-miRNAs were randomly selected to validate their expressions using quantitative reverse transcription polymerase chain reaction (qRT-PCR), the results showed that their expression profiles were consistent with those obtained by deep sequencing. The target genes of the DE-miRNAs covered a wide range of functions, such as regulation of transcription, oxidation-reduction process, proteolysis, regulation of apoptotic process, and immune response. In addition, the effects of four DE-miRNAs including miR-1, miR-30b, miR-150, and miR-184 on RGNNV replication were evaluated, and the results showed that over-expression of each of the four miRNAs promoted the replication of RGNNV. These data provide insight into the molecular mechanism of RGNNV infection, and will benefit for the development of effective strategies to control RGNNV infection.

Abstract
MicroRNA-126 (miR-126) has been found to promote angiogenesis, but the underlying mechanisms are still unclear. So, we conducted this study to explore the effect of miR-126 expression on angiogenesis in hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE). The expression levels of miR-126 and sprouty-related, EVH1 domain containing protein (Spred)1 in surgically resected HCC tissue, HCC tissue with TACE + operation, and tumor-adjacent tissues were determined by quantitative real-time polymerase chain reaction. The expression levels of miR-126, Spred1, and vascular endothelial growth factor were found by quantitative real-time polymerase chain reaction and Western blot. The microvessel density (MVD) of tumor tissues was determined by immunohistochemical staining. The miR-126 and Spred1 expressions in HCC tissue with TACE + operation were elevated and decreased, respectively, as compared to those in surgically resected HCC tissues and tumor-adjacent tissues (all P<0.001), which indicated that the expression of Spred1 was negatively correlated with miR-126 (P<0.001, r=−0.6224). Based on the bioinformatics analysis and luciferase reporter gene activity detection, Spred1 was found to target miR-126 (P<0.001). Inhibition of miR-126 expression reduces the degree of weight loss and tumor size in TACE model rats. The MVD in TACE + operation group was increased compared to that in the control group; inhibition of miR-126 expression had a reversal effect, to a certain extent, on MVD increase after TACE (all P<0.05). Inhibition of miR-126 expression increased Spred1 expression and decreased vascular endothelial growth factor expression (P<0.01). In summary, this study unveiled the potential mechanism by which miR-126 regulates angiogenesis in HCC tissues through embolization treatment by targeting Spred1, and also showed that the feasibility of TACE with the miR-126 inhibitor has a certain value in the medical treatment of HCC.

Profilings of MicroRNAs in the Liver of Common Carp (Cyprinus carpio) Infected with Flavobacterium columnare. Int J Mol Sci 2016; 17:566. [PMID: 27092486 PMCID: PMC4849022 DOI: 10.3390/ijms17040566] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2016] [Revised: 03/20/2016] [Accepted: 04/08/2016] [Indexed: 12/17/2022] Open
Abstract
MicroRNAs (miRNAs) play important roles in regulation of many biological processes in eukaryotes, including pathogen infection and host interactions. Flavobacterium columnare (FC) infection can cause great economic loss of common carp (Cyprinus carpio) which is one of the most important cultured fish in the world. However, miRNAs in response to FC infection in common carp has not been characterized. To identify specific miRNAs involved in common carp infected with FC, we performed microRNA sequencing using livers of common carp infected with and without FC. A total of 698 miRNAs were identified, including 142 which were identified and deposited in the miRbase database (Available online: http://www.mirbase.org/) and 556 had only predicted miRNAs. Among the deposited miRNAs, eight miRNAs were first identified in common carp. Thirty of the 698 miRNAs were differentially expressed miRNAs (DIE-miRNAs) between the FC infected and control samples. From the DIE-miRNAs, seven were selected randomly and their expression profiles were confirmed to be consistent with the microRNA sequencing results using RT-PCR and qRT-PCR. In addition, a total of 27,363 target genes of the 30 DIE-miRNAs were predicted. The target genes were enriched in five Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, including focal adhesion, extracellular matrix (ECM)-receptor interaction, erythroblastic leukemia viral oncogene homolog (ErbB) signaling pathway, regulation of actin cytoskeleton, and adherent junction. The miRNA expression profile of the liver of common carp infected with FC will pave the way for the development of effective strategies to fight against FC infection.
