Establishment and identification of a skin cell line from Chinese tongue sole (Cynoglossus semilaevis) and analysis of the changes in its transcriptome upon LPS stimulation. FISH & SHELLFISH IMMUNOLOGY 2023; 142:109119. [PMID: 37774902 DOI: 10.1016/j.fsi.2023.109119] [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: 08/24/2023] [Revised: 09/14/2023] [Accepted: 09/27/2023] [Indexed: 10/01/2023]
Abstract
The Chinese tongue sole (Cynoglossus semilaevis) holds significant economic importance within the fishing industry along the eastern coasts of China. In recent years, the frequent outbreaks of bacterial diseases have become a common concern as the aquaculture scale expands. The majority of the diseased fish exhibit symptoms such as skin congestion, damage and skin ulceration. As the skin serves as the first line of defense against bacterial infections, establishing a skin cell line for immunological research on Chinese tongue sole's response to bacterial infection is of utmost importance. In this study, a cell line named CSS (derived from the skin of the Chinese tongue sole) was successfully established. The cells have demonstrated stability during passages and exhibit a multipolar fibroblast-like morphology. They were cultured in L-15 medium with 20% serum and have been successfully passed through 60 passages over a period of 20 months. The identification of the mitochondrial CO1 gene confirmed that the cell originated from Chinese tongue sole. The karyotype detection revealed that the cell had a chromosome number of 2n = 42. After being stored in liquid nitrogen for 15 months, the cells can maintain more than 75% viability upon recovery. After transfecting with cy3-labeled scramble siRNA and pEGFP-N3 plasmid, clear fluorescence was observed in the transfected cells. We observed that lipopolysaccharide (LPS) from Escherichia coli significantly upregulate the gene expression of various immune-related pathways at 2 h in the CSS cell line. Additionally, the differentially expressed genes showed a higher enrichment in immune-related pathways at 2 and 6 h after stimulation compared to the 24 h point. Moreover, we identified 347 genes that exhibited a gradual increase in expression during the 0-24 h stimulation period. These genes were primarily enriched in pathways related to Autophagy, GABAergic synapse, Apelin signaling and Ferroptosis. In general, the CSS cell line established in this study exhibits stable growth and can serve as a valuable tool for in vitro studies of immunology and other basic biologies of Chinese tongue sole.

Abstract
Chinese perch (Siniperca chuatsi), an important fish for the aquaculture industry of China, is often affected by viral diseases. A stable and sensitive cell line can play an important role in virus identification and isolation, functional gene identification, virus pathogenic mechanism and antiviral immunity study. In the present study, a new cell line (S. chuatsi skin cell, SCSC) derived from the skin of S. chuatsi was established. The SCSC mainly consisted of fibroblastic-like cells, which grew well in M199 medium supplemented with 10% foetal bovine serum at 25°C. Chromosome analysis revealed that the SCSC (44%) has a diploid chromosome number of 2n = 48. The SCSC can be transfected and expressed exogenous gene efficiently. It also showed high sensitivity to several aquatic animal viruses from different families including Rhabdoviridae, Iridoviridae and Reoviridae. In addition, RT-PCR showed that S. chuatsi rhabdovirus (SCRV) started genome replication as early as 3 h post infection in the cells, which also induced the up-regulation of a variety of immune-related genes including these related to interleukin family, pattern recognition receptors, JAK-STAT pathway and interferon regulatory factors. In summary, current study provided a new tool in research of fish viruses and its interaction with host.

Abstract
A continuous cell line MPF derived from the fin of black carp Mylopharyngodon piceus was established and characterised in this study. Mylopharyngodon piceus fin (MPF) cells were subcultured for more than 80 passages with high viability recovery after long-term storage. The karyotyping analysis revealed that MPF had a modal diploid chromosome number (2n = 48) and identical ribosomal RNA sequence with black carp. In addition, the expression of pluripotency-associated markers including nanog, oct4 and vasa, were detected in MPF. The transient transfection efficiency of MPF reached 23% with a fluorescent reporter by modified electroporation and stable expression of red fluorescent MPF was established by the baculovirus system, indicating that MPF is an ideal platform for studying gene functions in vitro. Lastly, cytopathic effects were also observed and RNA transcripts of a viral gene increased after infection by spring viremia of carp virus (SVCV), suggesting that MPF could be an alternative tool for investigating pathogen-host interactions in black carp. In conclusion, a fin cell line that is susceptible to SVCV was established as a potential adult stem-cell line, providing a suitable tool for future genetic analyses and pathogen-host studies in black carp.

Abstract
A walleye dermal fibroblastoid cell line, WE-skin11f, was established and characterized. WE-skin11f was immunocytochemically positive for two known dermal fibroblast protein markers: vimentin and collagen I. At passage 26, WE-skin11f cultures contained both diploid and aneuploid populations. Ascorbic acid was required to produce extracellular collagen I fibres. Both of the skin fibroblastoid cell lines, WE-skin11f and rainbow trout-derived RTHDF, were not as good as the walleye caudal fin fibroblastoid cell line, WE-cfin11f, at forming abundant dense extracellular collagen matrices. The thermobiology of WE-skin11f was similar to that of other walleye cell lines with 26°C showing best temperature for growth and 4°C showing no growth but 100% viability. The transcript levels of b2m and mhIa genes of the major histocompatibility class I receptor in WE-skin11f were largely similar at all temperatures examined (4, 14, 20 and 26°C). Cortisol had a variety of effects on WE-skin11f cells: growth inhibition, morphological change from fibroblastoid to epithelioid, and enhancement of barrier function. Treatment of WE-skin11f cells with the physiologically relevant concentration of 100 ng/ml cortisol inhibited collagen I synthesis and matrix formation. Thus, WE-skin11f cell line could be useful in fish dermatology, endocrinology, and immunology research.

Abstract
In this study, we established and characterized a cell line derived from the kidney of black carp (Mylopharyngodon piceus), which is an important freshwater aquaculture species. The cell line was designated as MPK and subcultured for more than 70 passages in DMEM medium containing 10% fetal bovine serum (FBS) at 28°C. MPK had a modal diploid chromosome number of 48. Moreover, a transient MPK transfection efficiency was up to 18% using a green fluorescent protein plasmid by a modified electroporation. In addition, the MPK cells showed susceptibility to spring viremia of carp virus (SVCV), as demonstrated by the presence of severe cytopathic effects (CPEs) and increased viral RNA. Unexpectedly, the MPK cells expressed pluripotency-associated genes such as nanog, oct4 and vasa, indicating that these are possibly adult stem cells. Taken together, we have established a stable cell line from kidney that may potentially be utilized as an in vitro platform for genetic modifications and host-pathogen analysis in black carp.

Abstract
A cell line ZBE3 isolated from a continuous cell culture derived from zebrafish Danio rerio blastomeres by clonal growth was characterized. ZBE3 cells had been subcultured for >120 passages since the initial primary culture of the blastomeres. The ZBE3 cells grow stably at temperature from 20 to 32° C with an optimum temperature of 28° C in ESM2 or ESM4 medium with 15% foetal bovine serum (FBS). The optimum FBS concentration for ZBE3 cell growth ranged from 15 to 20%. Cytogenetical analysis indicated that the modal chromosome number of ZBE3 cells was 50, the same as the diploid chromosome number of D. rerio. Significant cytopathic effect was observed in ZBE3 cells after infection with redspotted grouper nervous necrosis virus, Singapore grouper iridovirus and grass carp reovirus, and the viral replication in the cells was confirmed by real-time quantitative PCR and transmission electron microscopy, indicating the susceptibility of ZBE3 cells to the three fish viruses. After transfected with pEGFP-N3 plasmid, ZBE3 cells showed a transfection efficiency of about 40% which was indicated by the percentage of cells expressing green fluorescence protein. The stable growth, susceptibility to fish viruses as well as high transfection efficiency make ZBE3 cells be a useful tool in transgenic manipulation, fish virus-host cell interaction and immune response in fish.

Abstract
The objective of this study was to investigate the optimal developmental time to perform sex reversal in Ussuri catfish Tachysurus ussuriensis, to develop monosex breeding in aquaculture. Systematic observations of gonadal sex differentiation of P. ussiriensis were conducted. The genital ridge formed at 9 days post fertilization (dpf) and germ cells begin to proliferate at 17 dpf. The ovarian cavity began forming on 21 dpf and completed by 25 dpf while presumptive testis remained quiescent. The primary oocytes were at the chromatin nucleolus stage by 30 dpf, the peri-nucleolus stage by 44 dpf and the cortical alveoli stage by 64 dpf. The germinal vesicle migrated towards the animal pole (polarization) at 120 dpf. In presumptive testis, germ cells entered into mitosis and blood vessels appeared in the proximal gonad on 30 dpf. The efferent duct anlage appeared on 36 dpf and formation of seminal lobules with spermatogonia and lobules interstitium occurred at 120 dpf. Therefore, gonadal sex differentiation occurred earlier in females than in males, with the histological differentiation preceding cytologic differentiation in T. ussuriensis. This indicates that undifferentiated gonads directly differentiate into ovary or testis between 17 and 21 dpf and artificial induction of sexual reversal by oral steroid administration must be conducted before 17 dpf.

Abstract
Moroxydine hydrochloride (Mor) and ribavirin (Rib) have been reported to exhibit multi-antiviral activities against DNA and RNA viruses, but their antiviral activities and pharmacologies have seldom been studied in aquaculture. This paper has selected 3 aquatic viruses including a double-stranded RNA virus (grass carp reovirus, GCRV), a single-stranded RNA virus (spring viraemia of carp virus, SVCV) and a DNA virus (giant salamander iridovirus, GSIV) for antiviral testing. The results showed that Mor and Rib can effectively control the infection of GCRV and GSIV in respective host cells. Further study was undertaken to explore the antivirus efficiencies and pharmacological mechanisms of Mor and Rib on GCRV and GSIV in vitro. Briefly, compounds showed over 50% protective effects at 15.9 µg ml-1 except for the group of GSIV-infected epithelioma papulosum cyprinid (EPC) cells treated with Mor. Moreover, Mor and Rib blocked the virus-induced cytopathic effects and apoptosis in host cells to keep the normal cellular structure. The expression of VP1 (GCRV) and major capsid protein (MCP; GSIV) gene was also significantly inhibited in the virus-infected cells when treated with Mor and Rib. Cytotoxicity assay verified the 2 compounds had no toxic effects on grass carp ovary (GCO) cells and EPC cells at ≤96 µg ml-1. In conclusion, these results indicated that exposing GCRV-infected GCO cells and GSIV-infected EPC cells to Mor and Rib could elicit significant antiviral responses, and the 2 compounds have been shown to be promising agents for viral control in the aquaculture industry.

Abstract
Newcastle disease virus is the most devastating virus in poultry industry. It can eradicate the entire poultry flocks once infected. This study is aimed to investigate the antiviral efficacy of novel phosphorylated analogues of the drug abacavir (ABC) against Newcastle disease virus (NDV). About 16 analogues of ABC were designed and docking was performed against fusion protein of NDV. Three compounds were identified and selected for synthesis and biological evaluation based on binding affinity and docking scores. The compounds were synthesized and characterized by IR, (1)H, (13)C, (31)P and CHN analysis and mass spectra. These compounds were tested for antiviral efficacy against NDV-infected DF-1 cells. Compound ABC-1 had shown potent antiviral activity as evidenced by significant reduction in plaque units and cytopathic effect. Therefore, ABC-1 was selected to test for NDV-infected chicken survival rate. Effective dose50 concentrations were determined for ABC-1. Antioxidant enzyme levels in brain, liver and lung tissues were estimated. Superoxide dismutase and catalase were significantly raised and lipid peroxidation and HA titer levels were decreased upon treatment with 2 mg/kg body weight ABC-1. Histopathological modifications were also restored in the ABC-1-treated group. These findings demonstrated ABC-1 as a potential antiviral agent against NDV in chicken.

Abstract
A series of novel phosphorylated derivatives of didanosine were designed and docking studies were performed with a fusion protein of the Newcastle disease virus (NDV), to develop antiviral compounds against NDV. Based on the docking scores and binding affinities, three derivatives were selected. These compounds were synthesized and characterized by IR, (1) H, (13) C, (31) P, and CHN analysis and mass spectra. They were assessed for their in vitro antiviral activity in DF-1 cells; DDI-10 showed better antiviral activity as evidenced by significant reduction in plaque formation and cytopathic effects. DDI-10 was further evaluated in NDV-infected chicken; the survival rates and antioxidant enzyme levels in brain, liver, and lung tissues were estimated. Superoxide dismutase and catalase were significantly raised, and lipid peroxidation and HA titer levels were decreased upon treatment with 1.5 mg/kg body weight of DDI-10 than with 3 mg/kg body weight of DDI. Further histopathological alterations in NDV-infected tissues were restored in chicken treated with DDI-10. Thus, based on the results from in silico, in vitro, and in vivo assays, the novel phosphorylated DDI-10 might be considered as potent antiviral compound for NDV infection in chicken.

Abstract
Grass carp reovirus strain 109 (GCReV-109) was previously isolated from a grass carp (Ctenopharyngodon idellus) with hemorrhagic disease, and its complete genome has been sequenced. However, the infectivity of GCReV-109 has not been studied, and the viral protein VP33, encoded on genome segment S11, had no detectable sequence homology to other known reovirus proteins. In this study, we characterized GCReV-109 infections in vivo and in vitro, as well as the VP33 protein. Infectivity analysis showed that GCReV-109 caused severe hemorrhagic disease and 100% mortality at dilutions up to 10(-4) in rare minnows (Gobiocypris rarus) by 8 days postinfection, but no visible cytopathic effect was observed in GCReV-109-infected subcultured grass carp muscle (GCM) cells. To confirm that GCReV-109 could be propagated in GCM cells, three virus genome segments were detected by RT-PCR, and large numbers of virus particles were observed by transmission electron microscopy in samples from the infected GCM cells. The suspension of GCReV-109-infected GCM cells was pathogenic to rare minnows. VP33 protein was expressed and purified for generation of an anti-VP33 antiserum. In western blot analysis of purified GCReV-109 particles, the antiserum specifically recognized a protein band (approximately 33 kDa). This revealed that VP33 is a major structural protein of GCReV-109 that might have immunogenic properties. The protective efficacy of the anti-VP33 antiserum against GCReV-109 infection was tested. The death of infected fish was delayed and the mortality fell to 10% when fish were treated with the anti-VP33 antiserum, suggesting that it might be useful for the prevention and control of fish reoviral disease.

Abstract
Known as lethal pathogens, Ranaviruses have been identified in diseased fish, amphibians (including Chinese giant salamander Andrias davidianus, the world’s largest amphibian) and reptiles, causing organ necrosis and systemic hemorrhage. Here, three Chinese giant salamander cell lines, thymus cell line (GSTC), spleen cell line (GSSC) and kidney cell line (GSKC) were initially established. Their sensitivities to ranaviruses, wild-type Andrias davidianus ranavirus (ADRV) and recombinant Rana grylio virus carrying EGFP gene (rRGV-EGFP) were tested. Temporal transcription pattern of ranavirus major capsid protein (MCP), fluorescence and electron microscopy observations showed that both the wild-type and recombinant ranavirus could replicate in the cell lines.
