Abstract
Fish primary cell culture has emerged as a valuable tool for investigating the physiological roles and responses of various cell types found in fish species. This review aims to provide an overview of the advancements and applications of fish primary cell culture techniques, focusing on the profiling of physiological roles exhibited by fish cells in vitro. Fish primary cell culture involves the isolation and cultivation of cells directly derived from fish tissues, maintaining their functional characteristics and enabling researchers to study their behavior and responses under controlled conditions. Over the years, significant progress has been made in optimizing the culture conditions, establishing standardized protocols, and improving the characterization techniques for fish primary cell cultures. The review highlights the diverse cell types that have been successfully cultured from different fish species, including gonad cells, pituitary cells, muscle cells, hepatocytes, kidney and immune cells, adipocyte cells and myeloid cells, brain cells, primary fin cells, gill cells, and other cells. Each cell type exhibits distinct physiological functions, contributing to vital processes such as metabolism, tissue regeneration, immune response, and toxin metabolism. Furthermore, this paper explores the pivotal role of fish primary cell culture in elucidating the mechanisms underlying various physiological processes. Researchers have utilized fish primary cell cultures to study the effects of environmental factors, toxins, pathogens, and pharmaceutical compounds on cellular functions, providing valuable insights into fish health, disease pathogenesis, and drug development. The paper also discusses the application of fish primary cell cultures in aquaculture research, particularly in investigating fish growth, nutrition, reproduction, and stress responses. By mimicking the in vivo conditions in vitro, primary cell culture has proven instrumental in identifying key factors influencing fish health and performance, thereby contributing to the development of sustainable aquaculture practices.

Abstract
Fish cell lines have become a useful tool to study in resource conservation, genetic breeding, diseases control, and environmental pollutants detection. The silver pomfret (Pampus argenteus) is a high-valued marine fish species in aquaculture, which is seriously threatened by various fish diseases. In this study, a new cell line derived from P. argenteus liver (PaL) was established and characterized. PaL cells mainly consisted of fibroblast-like morphology and multiplied well in Leibovitz's L-15 medium supplemented with 15% foetal bovine serum and 3 ng/mL basic fibroblast growth factor at 22°C. Amplification of the Cyt b gene confirmed that the origin of PaL cells as P. argenteus. Chromosome analysis revealed that PaL cells had a diploid Karyotyp. The PaL cells were efficiently transfected with pEGFP-N3 plasmids, indicating its potential application in foreign gene manipulation studies. The PaL cells were found to be susceptible to red sea bream iridovirus (RSIV) and the expression of immune-related gene (TLR5) and apoptosis-related genes (Bax, Cyt c3, CASP9) were upregulated. Furthermore, lipopolysaccharide and palmitic acid (PA) treatments decreased cell viability and up-regulated the expression of inflammation related genes (IL-8, IL-1β). Meanwhile, PA incubation induced cell apoptosis by Bcl-2-regulated caspase activation. In conclusion, the newly established PaL cell line will be an appropriate in vitro tool for viral propagation and immune response.

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.

AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2023; 257:106452. [PMID: 36863151 DOI: 10.1016/j.aquatox.2023.106452] [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: 09/15/2022] [Revised: 02/10/2023] [Accepted: 02/19/2023] [Indexed: 06/18/2023]
Abstract
Copper pollution might have a negative effect on collagen metabolism in fish. To test this hypothesis, we exposed an important economical fish, silver pomfret (Pampus argenteus), to three concentrations of Cu2+ for up to 21 days to simulate natural exposure to copper. With increasing copper exposure concentration and time, hematoxylin and eosin staining and picrosirius red staining revealed extensive vacuolization, cell necrosis, and tissue structure destruction, and a change of type and abnormal accumulation of collagen in the liver, intestine, and muscle tissues. To further study the mechanism of collagen metabolism disorder caused by copper exposure, we cloned and analyzed a key collagen metabolism regulation gene, timp, of silver pomfret. The full-length timp2b cDNA was 1035 bp with an open reading frame of 663 bp, encoding a protein of 220 amino acids. Copper treatment significantly increased the expression of akts, erks, and fgfs genes and decreased the mRNA and protein expression of Timp2b and MMPs. Finally, we constructed a silver pomfret muscle cell line (PaM) for the first time and used PaM Cu2+ exposure models (450 μM Cu2+ exposure for 9 h) to examine regulation function of the timp2b-mmps system. We knocked down or overexpressed timp2b in the model, and found that downregulation of mmps expression and upregulation of akt/erk/fgf were further aggravated in the timp2b- group (subjected to RNA interference), whereas some recovery was achieved in the timp2b+ group (overexpression). These results indicated that long-term excessive copper exposure can lead to tissue damage and abnormal collagen metabolism in fish, which might be caused by the alteration of akt/erk/fgf expression, which disrupts the effects of the timp2b-mmps system on extracellular matrix balance. The present study assessed the impact of copper on the collagen of fish and clarified its regulatory mechanism, providing a basis for toxicity of copper pollution study.

Abstract
Nervous necrosis virus (NNV), a highly pathogenic RNA virus, is a major pathogen in the global aquaculture industry. To efficiently infect fish, NNV must evade or subvert the host IFN for their replication; however, the precise mechanisms remain to be elucidated. In this study, we reported that capsid protein (CP) of red-spotted grouper NNV (RGNNV) suppressed the IFN antiviral response to promote RGNNV replication in Lateolabrax japonicus brain cells, which depended on the ARM, S, and P domains of CP. CP showed an indirect or direct association with the key components of retinoic acid-inducible gene-I-like receptors signaling, L. japonicus TNFR-associated factor 3 (LjTRAF3) and IFN regulatory factor (LjIRF3), respectively, and degraded LjTRAF3 and LjIRF3 through the ubiquitin-proteasome pathway in HEK293T cells. Furthermore, we found that CP potentiated LjTRAF3 K48 ubiquitination degradation in a L. japonicus ring finger protein 114-dependent manner. LjIRF3 interacted with CP through the S domain of CP and the transcriptional activation domain or regulatory domain of LjIRF3. CP promoted LjIRF3 K48 ubiquitination degradation, leading to the reduced phosphorylation level and nuclear translocation of LjIRF3. Taken together, we demonstrated that CP inhibited type I IFN response by a dual strategy to potentiate the ubiquitination degradation of LjTRAF3 and LjIRF3. This study reveals a novel mechanism of RGNNV evading host immune response via its CP protein that will provide insights into the complex pathogenesis of NNV.

Abstract
Understanding the metabolic effects of fatty acids on fish intestine is critical to the substitution of fish oil with vegetable oils in aquaculture. In this study, the effects of eicosapentaenoic acid (EPA) and palmitic acid (PA) on fish intestine were evaluated in vitro and in vivo. As the first step for in vitro study, an intestinal cell line (SPIF) was established from silver pomfret (Pampus argenteus). Thereafter, the effects of EPA and PA on cell viability, prostaglandin E2 (PGE2) production, and the expression of genes related to heat shock response, inflammation, extracellular matrix (ECM) formation and degradation were examined in SPIF cells. Finally, these metabolic effects of EPA and PA on the intestine were examined in zebrafish (Danio rerio) larvae. Results showed that all tested fatty acids (PA, oleic acid, linoleic acid, α-linolenic acid, arachidonic acid, and docosahexaenoic acid) except EPA reduced SPIF viability to distinct degrees at the same concentrations. PA decreased SPIF viability accompanied by an increase in PGE2 level. Meanwhile, PA increased the expression of genes related to heat shock response (grp78, grp94, hsp70, and hsp90) and inflammation (nf-κb, il-1β, and cox2). Furthermore, PA reduced the expression of collagen type I (col1a1a and col1a1b) and extracellular matrix (ECM) degradation-related gene mmp2, while up-regulating timp2 mRNA expression. In vivo, PA also increased hsp70, il-1β, and cox2 mRNA levels and limited the expression of collagen type I in the larval zebrafish intestine. Interestingly, the combination of EPA and PA partially recovered the PA-induced changes in cell viability, PGE2 production, and mRNA expression in vitro and in vivo. These results suggest that PA may result in heat shock and inflammatory responses, as well as alter ECM formation and degradation in fish intestine, while EPA could at least partially mitigate these negative effects caused by PA.

Abstract
Yellowfin sea bream (Acanthopagrus latus) is an important economic fish, which is seriously threatened by various fish viruses. In this study, a cell line designated as ALL derived from the liver of yellowfin sea bream was developed and characterized. The cell line grew well in Dulbecco's modified Eagle's medium containing 10%-20% foetal bovine serum at 28°C. Amplification of the cytochrome B gene indicated that ALL cells originated from yellowfin sea bream. The modal chromosome number of ALL cells was 48. ALL cells were efficiently transfected with pEGFP-N3 plasmids, indicating the potential application of ALL cells in exogenous gene manipulation studies. ALL cells were susceptive to three main fish viruses, including viral haemorrhagic septicaemia virus (VHSV), red-spotted grouper nervous necrosis virus (RGNNV) and largemouth bass virus (LMBV). The replication of VHSV, RGNNV and LMBV in ALL cells was confirmed by quantitative real-time polymerase chain reaction, virus titre and transmission electron microscopy assays. Moreover, ALL cells could respond to VHSV, RGNNV and LMBV infections, as indicated by the differential expression of antiviral genes involving in the innate immune response. In conclusion, the newly established ALL cell line will be an excellent in vitro platform for the study of the virus-yellowfin sea bream interaction.

Abstract
An important bottleneck in fish aquaculture research is the supply and maintenance of embryos, larvae, juvenile and adult specimens. In this context, cell lines represent alternative experimental models for in vitro studies that complement in vivo assays. This allows us to perform easier experimental design and sampling and avoid the sacrifice of animals. Embryonic stem (ES) cell lines have attracted increasing attention because they have the capability to proliferate indefinitely and could be differentiated into any cell type of the organism. To minimise cell heterogeneity and increase uniformity of in vitro studies results, in this manuscript we report the development and characterisation of two single cell-derived ES cell lines (monoclonal) from the morula stage embryos of the gilthead seabream, Sparus aurata, named as SAEC-A3 and SAEC-H7. Both cell lines have been passaged for over 100 times, indicating the establishment of long-term, immortalised ES cell cultures. Sequence analyses confirmed the seabream origin of the cell lines, and growth analyses evidenced their high viability and proliferating activity, particularly in culture medium supplemented with 10-15% fetal bovine serum and 22 °C. Both cell lines showed the ability to generate embryoid bodies and show different sensitivity and response to all-trans retinoic acid. The analysis of epithelial (col1α1) and neuronal (sox3) markers in differentiated cultures revealed that SAEC-A3 tended to differentiate towards epithelial-like cells whereas SAEC-H7 tended to differentiate towards neuronal-like cells. Both cell lines were efficiently transfected with pDsRed2-ER and/or pEGFP-N1 plasmids, indicating that they could represent useful biotechnological tools. Daily expression of pcna showed significant expression rhythms, with maximum levels of cell proliferation during the day-night transition. Currently, these cell lines are being successfully used as experimental models for the study of cellular metabolism, physiology and rhythms as well as for toxicological, pharmacological and gene expression analyses.

Hu L, Zhang S, Zhou Y, Liao K, Xu S, Wang D. Cloning and expression of Hoxc6 gene from Pampus argenteus and its relationship with pelvic fin absence. Gene Expr Patterns 2020; 39:119161. [PMID: 33309862 DOI: 10.1016/j.gep.2020.119161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 12/01/2020] [Accepted: 12/02/2020] [Indexed: 10/22/2022]
Abstract
Hoxc6 gene can be described as having roles in axial patterning in early embryogenesis, and in at least some species, having a contribution to limb positioning. In this study, we cloned and characterised Pampus argenteus Hoxc6. The highly conserved HOXC6 protein sequence contains a homeodomain and a low-complexity region. Expression of Hoxc6 mRNA was measured at different developmental stages and in different tissues by real-time PCR (p < 0.05), and was high during eye capsule and brain differentiation stages, but low in 7 and 13-day-old larvae. Hoxc6 mRNA was more abundant in fin tissue than brain and eye tissues. Western blotting showed that HOXC6 protein levels were high at embryonic stages, but decreased significantly in 7, 13, 16 and 19-day-old larvae, and levels were essentially consistent with those of mRNA measured by real-time PCR in different tissues. In situ hybridisation showed that the Hoxc6 transcript was strongly expressed in the whole brain and anterior part of the body axis in 1-day-old larvae, but in the hindbrain, pectoral fin, mandible and hypothetical pelvic fin region in 7, 13, 16 and 19-day-old organisms. These results clarify the expression and localisation characteristics of Hoxc6 gene in P. argenteus, and provide a theoretical basis for the molecular mechanism of pelvic fin loss in silver pomfret.
