Ficus hirta Vahl. alleviate LPS induced apoptosis via down-regulating of miR-411 in orange-spotted grouper (Epinephelus coioides) spleen cell. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2024; 157:105191. [PMID: 38705263 DOI: 10.1016/j.dci.2024.105191] [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: 01/24/2024] [Revised: 04/30/2024] [Accepted: 04/30/2024] [Indexed: 05/07/2024]
Abstract
Ficus hirta Vahl. (FhV) has been shown to have antimicrobial and antiviral efficacy. To further ascertain the pharmacological properties of FhV., and to search for alternatives to antibiotics. An in vitro experiment was carried out to evaluate what influence FhV. would have on LPS-induced apoptosis. In this study, Fas, an apoptosis receptor, was cloned, which included a 5'-UTR of 39 bp, an ORF of 951 bp, a protein of 316 amino acids, and a 3'-UTR of 845 bp. EcFas was most strongly expressed in the spleen tissue of orange-spotted groupers. In addition, the apoptosis of fish spleen cells induced by LPS was concentration-dependent. Interestingly, appropriate concentrations of FhV. alleviated LPS-induced apoptosis. Inhibition of miR-411 further decreased the inhibitory effect of Fas on apoptosis, which reduced Bcl-2 expression and mitochondrial membrane potential, enhanced the protein expression of Bax and Fas. More importantly, the FhV. could activate miR-411 to improve this effect. In addition, luciferase reporter assays showed that miR-411 binds to Fas 3'-UTR to inhibit Fas expression. These findings provide evidence that FhV. alleviates LPS-induced apoptosis by activating miR-411 to inhibit Fas expression and, therefore, provided possible strategies for bacterial infections in fish.

Wang X, Chen X, Sun X, Ao J. Comparative analysis of miRNAs and mRNAs in large yellow croaker head kidney cells (LYCK) provided novel insights into the redox regulation of fish. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 918:170503. [PMID: 38301776 DOI: 10.1016/j.scitotenv.2024.170503] [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: 10/04/2023] [Revised: 12/21/2023] [Accepted: 01/25/2024] [Indexed: 02/03/2024]
Abstract
Reactive oxygen species (ROS) over-production and oxidative stress resulted from climate change and environmental pollution seriously endangered global fish populations and healthy development of marine aquaculture. Peroxiredoxins (Prxs), a highly conserved family of thiol-specific antioxidants, can mitigate ROS and protect cells from oxidative stress. We previously demonstrated that large yellow croaker PrxIV (LcPrxIV) could not only regulate the pro-inflammatory responses, but also scavenge ROS. However, the underlying mechanism how LcPrxIV regulated immune response and redox homeostasis remains unknown. MicroRNAs (miRNAs) are non-coding RNAs that play important roles in the regulation of various biological processes. In this study, mRNA and miRNA expression profiles from LYCK-pcDNA3.1 and LYCK-PrxIV cells, with or without oxidative stress stimulated by H2O2 were evaluated using high-throughput sequencing. A series of differentially expressed miRNAs (DEMs) and differentially expressed genes (DEGs), as well as DEM-DEG pairs were identified from each two-group comparison, respectively. GO and KEGG functional analyses indicated that most significant DEGs were associated with signaling pathways related to oxidative stress and immune response. Subsequent DEM-DEG interaction analysis revealed that miR-731 and miR-1388 may be involved in both redox regulation and immune response via synergistic effect with LcPrxIV. Interestingly, miR-731 could regulate the expression of different down-stream DEGs under different stimulations of LcPrxIV over-expression, H2O2, or both. Moreover, miR-731 could cause the DEG, γ-glutamyl hydrolase (GGH), to be expressed in opposite ways under different stimulations. On the other hand, the expression of miR-1388 could be negatively or positively regulated under the stimulation of LcPrxIV over-expression with or without oxidative stress, thus regulating gene expression of different mRNAs. Based on these results, we speculate that LcPrxIV may participate in immune response or redox regulation by regulating the expression of different down-stream genes through controlling the expression level of a certain miRNA or by regulating the varieties of expressed miRNAs.

Abstract
Micro RNAs (miRNAs) are short non-coding RNAs that act as post-transcriptional gene expression regulators. Genes regulated in vertebrates include those affecting growth and development or stress and immune response. Pikeperch (Sander lucioperca) is a species that is increasingly being considered for farming in recirculation aquaculture systems. We characterized the pikeperch miRNA repertoire to increase the knowledge of the genomic mechanisms affecting performance and health traits by applying small RNA sequencing to different developmental stages and organs. There were 234 conserved and 8 novel miRNA genes belonging to 104 families. A total of 375 unique mature miRNAs were processed from these genes. Many mature miRNAs showed high relative abundances or were significantly more expressed at early developmental stages, like the miR-10 and miR-430 family, let-7, the miRNA clusters 106-25-93, and 17-19-92. Several miRNAs associated with immune responses (e.g., slu-mir-731-5p, slu-mir-2188-5p, and slu-mir-8159-5p) were enriched in the spleen. The mature miRNAs slu-mir-203a-3p and slu-mir-205-5p were enriched in gills. These miRNAs are similarly abundant in many vertebrates, indicating that they have shared regulatory functions. There was also a significantly increased expression of the disease-associated miR-462/miR-731 cluster in response to hypoxia stress. This first pikeperch miRNAome reference resource paves the way for future functional studies to identify miRNA-associated variations that can be utilized in marker-assisted breeding programs.

Abstract
Rainbow trout (Oncorhynchus mykiss) is a representative species of cold-water fish. Elevated temperatures during summer often result in significant high mortality rates. MicroRNAs (miRNAs) are class of small non-coding RNAs that play a crucial role as post-transcriptional regulators in various biological processes. Emerging evidence suggests that miRNAs are important regulators role during heat stress. Analyzing previously obtained miRNA-sequencing data, we observed substantial down regulation of miR-8159-x in the liver tissue of heat stressed rainbow trout. In this study, we conducted a dual luciferase reporter assay to validate that miR-8159-x target, a key gene involved in heat stress in rainbow trout. By examining the expression patterns of miR-8159-x and hsp90a1 in the liver tissue at 18 °C (CG) and 24 °C (HS) groups, we propose that miR-8159-x may negatively regulate hsp90a1. Furthermore, in vitro hepatocyte assay, transfection with miR-8159-x mimics significantly reduced the expression level of hsp90a1, whereas transfection with a miR-8159-x inhibitor yielded the opposite effect. Additionally, overexpression of miR-8159-x inhibited cell proliferation and induced apoptosis in normal rainbow trout hepatocytes. We further investigated the effects of miR-8159-x overexpression or inhibition on the mRNA and protein levels of the target gene hsp90a1 under heat stress conditions. In conclusion, our findings suggest that miR-8159-x participates in the biological response to heat stress by targeting hsp90a1. These results contribute to a better understanding of the molecular mechanisms underlying heat stress in rainbow trout and provide valuable insights for future research.

FISH & SHELLFISH IMMUNOLOGY 2023; 140:108939.

Abstract
Burbot (Lota lota), a fish species of economic and ecological significance found across northern hemisphere freshwater ecosystems, was the focus of this study. We characterized 19 Toll-like receptor (TLR) genes in burbot, tracing their expression patterns following pathogen exposure. TLR genes, crucial to the innate immune system, including TLR13-1/2/3, TLR2/2-2/2-3/2-4/2-5, and TLR22a/22b/22c/22d, were discovered to be tandemly repeated, signifying an evolution in the fish's immune system. Notably, different TLR subfamilies displayed tissue-specific expressions, with TLR1 primarily in spleen and head kidney, TLR13 in head kidney, trunk kidney, and heart, TLR22 in trunk kidney and liver, and TLR3 and TLR9 predominantly in spleen and head kidney, but also in trunk kidney. Further, we investigated the response of TLR genes in burbot to pathogen exposure using qRT-PCR. This involved measuring mRNA expressions of identified TLR genes in spleen and liver tissues after injecting Poly(I:C) to simulate a double-stranded RNA viral infection. The results revealed a time and tissue-specific expression pattern. Specifically, LoTLR3 reached peak expression in the spleen 12 h post-injection, declining thereafter, while TLR2 subfamily members only began expressing after 24 h. In the liver, activation of the TLR3-IRF7 and TLR3-IRF3 signaling pathways was noted. Integrating these results with transcriptomic data illuminated the pivotal role of TLR genes in the burbot's immune response. Such findings are vital in shaping future disease prevention and treatment strategies.

MicroRNA expression profile in Lampetra morii upon Vibrio anguillarum infection and miR-4561 characterization targeting lip. Commun Biol 2021; 4:995.

Abstract
As a critical evolutionary pivot between invertebrates and vertebrates, lampreys provide rich genetic information. Lamprey immune protein (LIP) is a key immune regulator. MicroRNAs, well-conserved in the response to immunological stress, remain understudied in lamprey immunity. We generated a lamprey microRNA expression atlas, using deep sequencing, upon Vibrio anguillarum infection. Using comparative methods, we found that miR-4561 potentially regulates innate immunity via interaction with lip. We found a sequence in the 3′-UTR region of LIP mRNA complementary to the miR-4561 seed region; miR-4561 expression was negatively correlated with LIP. During V. anguillarum infection, miR-4561 inhibited LIP expression and bacterial clearance. Notably, LIP expression in supraneural body cells was necessary for the Gram-negative immune response. Additionally, we observed that overexpression of miR-4561 induced apoptosis in embryonic cells, suggesting a role in embryonic development. Collectively, we show lamprey microRNAs may significantly affect gene regulation and provide new insights on LIP-mediated immune regulation. Ma et al characterise differentially expressed miRNAs in Lamprey upon bacterial infection. They identify miR-4561 as being decreased after infection and show that it targets the 3′UTR of the mRNA encoding lamprey immune protein (LIP) involved in lamprey innate immunity and regulates survival in lamprey embryos.

Abstract
Toll-like receptors (TLRs) are a large group of pattern recognition receptors which are involved in the regulation of innate immune responses. Based on the interplay between TLRs and adapter molecules, two distinctive signaling cascades, namely the MyD88-dependent and TRIF-dependent pathways have been recognized. TLRs are involved in the development of a wide variety of diseases including cancer and autoimmune disorders. A large body of evidence has shown interaction between two classes of non-coding RNAs, namely microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). These interactions have prominent roles in the pathogenesis of several disorders including infectious disorders, autoimmune conditions and neoplastic disorders. This review aims at description of the interaction between these non-coding RNAs and TLRs.

Abstract
MicroRNAs (miRNAs) play an important role in regulating gene expression, and myostatin (MSTN) has been widely recognized as a key gene for muscle growth and development. Through high-throughput sequencing to study the effects of starvation on miRNA transcriptomes in Larimichthys crocea muscle tissue, we found that the expression of miR-2014, miR-1231 and miR-1470 were significantly different between fasting and normal feeding Larimichthys crocea. Bioinformatics analysis predicted that miR-2014, miR-1231 and miR-1470 target MSTN mRNA 3'UTR. To verify the accuracy of predictions, we constructed double luciferase plasmids containing MSTN 3'UTR and confirmed that miR-2014-5p and miR-1231-5p can inhibit MSTN expression by targeting MSTN 3'UTR using double luciferase experiments, while miR-1470 is not involved in regulation. Subsequent site-directed mutation experiments reflected the specificity of the target sequence. In addition, quantitative PCR experiments revealed that miR-2014-5p and miR-1231-5p may participate in the regulation of MSTN expression in fasting and refeeding period, respectively. These results implied that miRNA may take part in muscle growth regulation during starvation. It provides some insights into the molecular regulation mechanism of MSTN in response to starvation stress in fish.

Abstract
IMPACT STATEMENT The delivery of short snippets of RNA, such as synthetic miRNA agents, is an essential step for achieving RNA-mediated knockdown, which has not been studied in sufficient detail in fish. Our results indicate that a MiR92b-3p mimic may be effectively delivered via intraperitoneal injection to the spleen and the liver of whitefish, and that it likely achieves functionality without causing any apparent toxic effects in the challenged animals. We report the novel finding that the MiR92b-3p mimic reduced the in vivo liver mRNA expression levels of its putative pro-apoptotic targets (p53, cdkn1a, and pcna), and important metabolic genes, e.g. cdo1. This shows that this methodology of MiR92b-3p mimic transfection in vivo may be a useful tool for studies that investigate the molecular pathways that confer pro-proliferative and anti-apoptotic phenotypes or those that regulate intracellular metabolism in fish and other vertebrates.

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
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.
