Wu L, Lv X, Zhang J, Wu M, Zhao X, Shi X, Ma W, Li X, Zou Y. Roles of β-catenin in innate immune process and regulating intestinal flora in Qi river crucian carp (Carassius auratus). FISH & SHELLFISH IMMUNOLOGY 2024; 148:109521. [PMID: 38552889 DOI: 10.1016/j.fsi.2024.109521] [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: 11/21/2023] [Revised: 03/12/2024] [Accepted: 03/19/2024] [Indexed: 04/04/2024]
Abstract
In mammals, β-catenin participates in innate immune process through interaction with NF-κB signaling pathway. However, its role in teleost immune processes remains largely unknown. We aimed to clarify the function of β-catenin in the natural defense mechanism of Qi river crucian carp (Carassius auratus). β-catenin exhibited a ubiquitous expression pattern in adult fish, as indicated by real-time PCR analysis. Following lipopolysaccharide (LPS), Polyinosinic-polycytidylic acid (polyI: C) and Aeromonas hydrophila (A. hydrophila) challenges, β-catenin increased in gill, intestine, liver and kidney, indicating that β-catenin likely plays a pivotal role in the immune response against pathogen infiltration. Inhibition of the β-catenin pathway using FH535, an inhibitor of Wnt/β-catenin pathway, resulting in pathological damage of the gill, intestine, liver and kidney, significant decrease of innate immune factors (C3, defb3, LYZ-C, INF-γ), upregulation of inflammatory factors (NF-κB, TNF-α, IL-1, IL-8), and downregulation of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) activities, increase of Malondialdehyde (MDA) content. Following A. hydrophila invasion, the mortality rate in the FH535 treatment group exceeded that of the control group. In addition, the diversity of intestinal microflora decreased and the community structure was uneven after FH535 treatment. In summary, our findings strongly suggest that β-catenin plays a vital role in combating pathogen invasion and regulating intestinal flora in Qi river crucian carp.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 146:104744. [PMID: 37230373 DOI: 10.1016/j.dci.2023.104744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/21/2023] [Accepted: 05/23/2023] [Indexed: 05/27/2023]
Abstract
Recent findings regarding the immunomodulatory role of Wnt signaling suggest that it is significant in regulating the differentiation and proliferation of immune cells. In the present study, a Wnt-1 homolog (designated as CgWnt-1) with a conserved WNT1 domain was identified from oyster Crassostrea gigas. The transcripts of CgWnt-1 were barely expressed in egg to gastrula stage during early embryogenesis, and up-regulated significantly in the trochophore to juvenile stage. The mRNA transcripts of CgWnt-1 were detected in different tissues of adult oyster, with an extremely high expression level in the mantle, which was 77.38-fold (p < 0.05) of that in labial palp. After Vibrio splendidus stimulation, the mRNA expression levels of CgWnt-1 and Cgβ-catenin in haemocytes up-regulated significantly at 3, 12, 24, and 48 h (p < 0.05). After injection of recombinant protein (rCgWnt-1) into oyster in vivo, the expressions of Cgβ-catenin, cell proliferation related genes CgRunx-1 and CgCDK-2 in haemocytes significantly up-regulated, which were 4.86-fold (p < 0.05), 9.33-fold (p < 0.05), 6.09-fold (p < 0.05) of those in rTrx group, respectively. The percentage of EDU+ cells in haemocytes also significantly increased (2.88-fold of that in control group, p < 0.05) at 12 h after rCgWnt-1 treatment. When the Wnt signal inhibitor C59 was injected simultaneously with rCgWnt-1, the expressions of Cgβ-catenin, CgRunx-1, and CgCDK-2 were significantly reduced, which were 0.32-fold (p < 0.05), 0.16-fold (p < 0.05), and 0.25-fold (p < 0.05) of that in rCgWnt-1 group, respectively, and the percentage of EDU+ cells in haemocytes was also significantly inhibited (0.15-fold compared with that in rCgWnt-1 group, p < 0.05). These results suggested that the conserved CgWnt-1 could modulate haemocytes proliferation via regulating cell cycle related genes and involved in the immune response of oysters.

Abstract
Invertebrates are considered completely dependent on their innate immunity to defend themselves against pathogens as they lack an adaptive immunity. However, a growing body of evidence has indicated a specific acquired immunity called 'immune priming' may exist. The Pacific white shrimp, Penaeus vannamei is one of the most economically important shrimp species in the world. In the previous research, we investigated the hepatopancreas immune response of shrimp immunized with trans -vp28 gene Synechocystis sp. PCC6803 at the protein level. In this study, on the basis of the previous research, the shrimp were then challenged with WSSV, and hepatopancreas analyzed using isobaric tags for relative and absolute quantification (i TRAQ) labeling. In total, 308 differentially expressed proteins (DEPs) were identified including 84 upregulated and 224 downregulated. Upregulated proteins such as calmodulin B and calreticulin, and downregulated proteins such as calnexin, and signaling pathways like Ras, mTOR were differentially expressed in both studies. Data from this study are more significant than previous work and indicate increased sensitivity to WSSV after immunization with trans-vp28 gene Synechocystis sp. PCC6803. In addition, selected DEPs (upregulated: A0A3R7QHH6 and downregulated: A0A3R7PEF6, A0A3R7MGX8, A0A423TPJ4, and A0A3R7QCC2) were randomly analyzed using parallel reaction monitoring (PRM). These data preliminarily confirm immune priming in P. vannamei, and show that the initial stimulation with trans -vp28 gene Synechocystis sp. PCC6803 regulate P. vannamei immune responses and they provide shrimp with enhanced immune protection against secondary stimulation.

Abstract
β-catenin is a multifunctional protein that participates in a variety of physiological activities, including immune regulation, sex determination, nervous system development and, cell differentiation. However, the function of β-catenin in freshwater mussel Hyriopsis cumingii remains unclear. Herein, the gene encoding β-catenin from H. cumingii (Hc-β-catenin) was cloned and characterised. The full-length 5544 bp gene includes an open reading frame (ORF) of 2463 bp encoding a putative protein of 820 amino acids residues containing 12 armadillo (ARM) repeats. After injecting H. cumingii with Aeromonas hydrophila or lipopolysaccharides, Hc-β-catenin transcription was induced in hemocytes and gills, and the greatest responses occurred at 24 h after bacterial challenge, confirming an important role in immune responses. Quantitative real-time PCR analysis showed that Hc-β-catenin mRNA was distributed in the gill, foot, liver, kidney, mantle, adductor muscle and gonad of male and female mussels. In gonad, Hc-β-catenin expression was markedly higher in females than males. During the embryonic period, Hc-β-catenin expression was highest at 3 day. In 1-, 2- and 3-year-old mature mussels, Hc-β-catenin expression in female gonad tissue was notably higher than in males. In situ hybridisation revealed a significant hybridisation signal in female gonads, indicating that Hc-β-catenin is a pro-ovarian, anti-testis gene. Our findings demonstrate that Hc-β-catenin is important in immune regulation and sex determination in freshwater mussel.

Abstract
GSK3β, a serine/threonine protein kinase, is a crucial regulator in several signaling pathway and plays a vital role in multiple cellular processes including cell proliferation, growth, apoptosis and immune response. In this study, a GSK3β homolog from L. vannamei, designed as LvGSK3β, was characterized. Sequence analysis showed that LvGSK3β possessed a highly similarity with GSK3β from other species, which contained a catalytic domain and serine/threonine phosphorylation sites. To analyze the role of LvGSK3β in the process of white spot syndrome virus (WSSV) infection, real-time quantitative PCR and western blot assays were performed. The results showed that the transcription and expression levels of LvGSK3β were inhibited upon WSSV challenge, accompanied with down-regulated phosphorylation levels. When LvGSK3β was silenced, the transcription of WSSV gene ie1 was inhibited, and the apoptosis of hemocytes induced by WSSV was up-regulated remarkably as well. In addition, inactivation of LvGSK3β could also depress virus infection that further validated the results. Conclusively, LvGSK3β was an important protein for shrimp immunomodulation, and shrimp might promote the apoptosis to restrain WSSV infection by inhibition of LvGSK3β. The study will be helpful for understanding the molecular mechanism of host-virus interaction.

Abstract
Numerous studies suggest R-spondins (Rspos) plays a role in mammalian sex development and differentiation by activating WNT signaling pathways. However, Rspos are frequently less reported in teleosts. In this study, a molecular characterization and expression analysis was conducted with a new rspondin member in the Chinese tongue sole, rspondin2-like (rspo2l). The length of rspo2l cDNA is 1251 bp with 732 bp of coding sequence. A qRT-PCR analysis revealed that the transcription of rspo2l was distributed in various tissues, with high transcription levels in the liver, skin, and gills which might indicate a possible role in immunity. We next examined a time-course of transcription levels in four immune tissues (gill, liver, spleen, and kidney) after Vibrio harveyi challenge. It was found that rspo2l was up-regulated in the gills, spleen, and kidney and down-regulated in the liver, and the greatest responses occurred at 24 and 48 h after bacterial challenge. An assessment of β-catenin, the key regulator of the canonical WNT signaling pathway, at different time points in four immune organs revealed that its transcription profile was similar to that of rspo2l after bacterial challenge. The results suggest that tongue sole rspo2l might play a role in immune responses after bacterial challenge, while the potential link with the WNT signaling pathway still requires further investigation. This is the first report about the involvement of rspondins in fish immune responses.

Abstract
Death-associated protein 1 (DAP1) is a small proline-rich cytoplasmic protein that functions both in the apoptosis and autophage process of mammalian and in the clinical cancer of human. However, little knowledge is known about the homologue gene of DAP1 and its roles in the physiological process of invertebrates. In this paper, we report a novel function of DAP1 in the antivirus immunity of shrimp. A homologue gene of DAP1 was cloned from Marsupenaeus japonicus and named as Mjdap-1. The full-length of Mjdap-1 was 1761 bp with a 309 bp open reading frame that encoded 102 amino acids. Reverse transcription-PCR results showed that Mjdap-1 was expressed in all tested tissues, including hemocytes, gills, intestines, stomach, heart, hepatopancreas, testes, and ovaries. In shrimp, Mjdap-1 transcripts were up-regulated by white spot syndrome virus (WSSV) infection; Mjdap-1 knockdown decreased the virus copy in vivo and the mortality of M. japonicus to WSSV challenge. Conversely, injecting the purified recombinant MjDAP1 protein promoted the amplification of virus in shrimp. Flow cytometric assay showed, the virus infection-induced apoptosis of hemocytes was enhanced by MjDAP1 protein injection and inhibited in MjDAP1 knockdown shrimp. Furthermore, the expression of apoptosis-inducing factor (AIF) was regulated by Mjdap-1, but the caspase transcripts were not affected. Our results suggested that MjDAP1 facilitated the amplification of virus in shrimp, which may be attributed to the promotion of hemocyte apoptosis in an AIF-dependent manner. These results provided a new insight into the function of this protein that may be used for virus disease control.

Abstract
Wnt signaling is known to control multiple of cellular processes such as cell differentiation, communication, apoptosis and proliferation, and is also reported to play a role during microbial infection. β-catenin is a key regulator of the Wnt signaling cascade. In the present study, we cloned and identified a β-catenin homologue from Litopenaeus vannamei termed Lvβ-catenin. The full-length of Lvβ-catenin transcript was 2797 bp in length within a 2451 bp open reading frame (ORF) that encoded a protein of 816 amino acids. Lvβ-catenin protein was comprised of several characteristic domains such as an N-terminal region of GSK-β consensus phosphorylation site and Coed coil section, a central region of 12 continuous Armadillo/β-Catenin-like repeat (ARM) domains and a C-terminal region. Real-time PCR showed Lvβ-catenin expression was responsive to Vibrio parahaemolyticus and white spot syndrome virus (WSSV) infection. Dual-reporter analysis showed that over-expression of Lvβ-catenin could induce activation of the promoter activities of several antimicrobial peptides (AMPs) such as shrimp PEN4, suggesting that Lvβ-catenin could play a role in regulating the production of AMPs. Knockdown of Lvβ-catenin enhanced the sensitivity of shrimps to V. parahaemolyticus and WSSV challenge, suggesting Lvβ-catenin could play a positive role against bacterial and viral pathogens. In summary, the results presented in this study provided some insights into the function of Wnt/β-catenin of shrimp in regulating AMPs and the host defense against invading pathogens.
