Abstract
Zinc (Zn) is an essential trace element for the normal physiological function of aquatic organisms, but it could become toxic to organisms when the concentration increased in water. As the first line of defense, the shrimp intestines are the most susceptible organ to environmental stress. In this study, the chronic toxicity of 0 (control, IC), 0.01(IL), 0.1(IM) and 1 mg/L (IH) Zn in intestines of Litopenaeus vannamei was investigated from the perspectives of biochemical, histological and transcriptional changes after exposure for 30 days. The results showed that the intestinal tissue basement membrane is swollen in the IM and IH groups and detached in the IH group. The total antioxidant capacities (T-AOC) were reduced while the content of malondialdehyde (MDA) were increased significantly in IM and IH groups. The production of reactive oxygen species (ROS) was increased significantly in IH group. Many differentially expressed genes (DEGs) were identified in IL, IM and IH groups, respectively. GO and KEGG enrichment analyses were conducted on the DEGs to obtain the underlying biological processes and pathways. The gene modules related to the sample were identified by weighted gene co-expression network analysis (WGCNA), and genes in modules highly corelated with IH group were mainly enriched in immune related pathways. Nine DEGs were selected for validation by quantitative real time PCR (qRT-PCR) and the expression profiles of these DEGs kept a well consistent with the high-throughput data, which confirmed reliability of transcriptome results. Additionally, 10 DEGs were screened to detect the changes of expression level in different groups. All these results indicated that Zn exposure could damage the intestinal barrier, provoke oxidative stress, reduce the immune function, increase the susceptibility to bacterial infections of L. vannamei and cause inflammation, ultimately result in cell apoptosis. Our study provides more perspective on the stress response of crustacean under Zn exposure.

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
Wnt proteins are a class of hydrophobic secreted glycoproteins involved in diverse important biological processes, such as tissue formation and regeneration, embryonic development and innate immunity. The Wnt gene family has an early origin and is present in all deuterostomes. In the process of evolution, the phenomenon of gene expansion, contraction and adaptive evolution occurs in the Wnt gene family. In the current study, eleven Wnt genes (NdWnt1-2, NdWnt4-7, NdWnt9-11, NdWnt16, and NdWntA) belonging to different subfamilies were obtained based on the genomic and transcriptomic data of Neocaridina denticulata sinensis. Then the expression patterns of all NdWnts were analyzed in various tissues, at different developmental stages and under different stresses. The expression profiles of NdWnts at different developmental stages showed that most NdWnt genes were initially expressed at gastrula stage, and the expression of NdWnt5 and NdWnt16 throughout all developmental stages. The spatial expression of NdWnt genes presented tissue specificity. They were mainly expressed in four tissues, namely gill, intestines, ovary and eyestalk. After Vibrio parahemolyticus infection and under copper exposure, the expression levels of five NdWnts (NdWnt1, NdWnt5, NdWnt10, NdWnt16 and NdWntA) were variable. Our findings enrich the research on the Wnt gene family of N. denticulata sinensis and provide valuable insights into relationship between structure and function of Wnt genes in crustaceans.

Abstract
The Wnt gene family is of ancient origin and is involved in various biological processes. In this study, Wnt4 and Wnt16 were cloned from Daphnia pulex, named DpWnt4 and DpWnt16, respectively. In DpWnt4 cDNA, full-length 1684 bp, the open reading frame was 1122 bp and it encodes a 373 amino acid polypeptide. In DpWnt16 cDNA, full-length 1941 bp, the open reading frame was 1293 bp and it encodes a 430 amino acid polypeptide. The sequence analysis result showed that both DpWnt4 and DpWnt16 sequences contain a Wnt1 domain. Multiple sequence alignment and phylogenetic analysis revealed that DpWnt4 and DpWnt16 were most closely related to arthropods. The expression of DpWnt4 decreased at 0.5 mg/L group and was induced at 2 mg/L, while DpWnt16 was only induced at 2 mg/L nanoplastics group. These results help us understand more about the character of Wnt4 and Wnt16 in crustaceans and how Wnt genes respond to pollutants, especially nanoplastics.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2022; 133:104411.

Abstract
The Wnt family genes are essentially implicated in development and growth in animals. Accumulating clues have pointed to the importance of Wnts in invertebrate immunity, but the underlying mechanisms are still unclear to date. The Wnt5b has been known to promote white spot syndrome virus (WSSV) infection in shrimp but its role in antibacterial response remains unclear. In the current study, we focused on the involvement of Wnt5b in Vibrio parahaemolyticus infection in Pacific white shrimp Penaeus vannamei. We demonstrated that the expression of Wnt5b was regulated by the IMD-Relish and JAK-STAT pathways but not the Dorsal pathway and was suppressed upon bacterial infection. Although Wnt5b did not affect the cellular immunity in shrimp, it was involved in regulation of humoral immunity. Silencing of Wnt5b in vivo significantly increased expression of several antimicrobial peptides but decreased that of many immune functional proteins including C-type lectins and lysozymes. Treatment with recombinant Wnt5b protein increased the susceptibility of shrimp to V. parahaemolyticus infection, while silencing of Wnt5b in vivo showed an opposite result. These suggested that Wnt5b plays a negative role in antibacterial response in shrimp. Together with previous reports, the current study shows that Wnt5b functions as an inhibitor for shrimp immunity, which is a potential target for improving immune responses against infection.

FISH & SHELLFISH IMMUNOLOGY 2022; 124:230-243. [PMID: 35421572 DOI: 10.1016/j.fsi.2022.03.050] [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: 03/01/2022] [Revised: 03/29/2022] [Accepted: 03/31/2022] [Indexed: 06/14/2023]
Abstract
As a highly conserved serine/threonine kinase with catalytic and regulatory subunits distributed ubiquitously in eukaryotic organisms, casein kinase 2 (CK2) is involved in multiple cellular functions, including immune regulation. In this study, two variants of the catalytic subunit (designated PvCK2α-1 and PvCK2α-2) and the regulatory subunit homologs (designated PvCK2β-1 and PvCK2β-2) in Penaeus vannamei were cloned and characterised. PvCK2α-1 and PvCK2α-2 shared the same genomic sequence consisting of six exons and five introns and encoded the same protein of 350 amino acids with an S_TKc domain, although there was a sequence deletion in 3'-UTR in PvCK2α-2 when compared with PvCK2α-1. Because of the sequence deletion in the ORF, PvCK2β-1 and PvCK2β-2 encoded different proteins with a CK_II_beta domain. The gene structures of PvCK2β-1 and PvCK2β-2 were identical and consisted of four exons and three introns. Semi-quantitative RT-PCR analyses revealed that PvCK2α and PvCK2β were constitutively expressed in all P. vannamei tissues tested, with higher levels detected in the immune-related tissues including hemocytes, hepatopancreas, gills and intestine. In these four tissue types, all variants of PvCK2α and PvCK2β were induced upon challenge with white spot syndrome virus (WSSV), Vibrio parahaemolyticus and Staphyloccocus aureus. The inhibition of PvCK2α, PvCK2β-1 and PvCK2βComb (the amount of PvCK2β-1 and PvCK2β-2) significantly reduced the survival rates of P. vannamei after WSSV infection and significantly increased the WSSV viral loads. Knockdown of PvCK2 by RNAi could distinctly decrease the expression of NF-κB related genes. All of these results suggest that PvCK2 plays an important role in the innate immune response to pathogen challenges in P. vannamei, with a positive role in anti-WSSV response which may be mediated through regulating the expression of NF-κB drived antimicrobial peptide genes.

RNA Sequencing Analysis Reveals Divergent Adaptive Response to Hypo- and Hyper-Salinity in Greater Amberjack ( Seriola dumerili) Juveniles. Animals (Basel) 2022; 12:327. [PMID: 35158652 PMCID: PMC8833429 DOI: 10.3390/ani12030327] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 01/23/2022] [Accepted: 01/24/2022] [Indexed: 02/01/2023] Open
Abstract
Salinity significantly affects physiological and metabolic activities, breeding, development, survival, and growth of marine fish. The greater amberjack (Seriola dumerili) is a fast-growing species that has immensely contributed to global aquaculture diversification. However, the tolerance, adaptation, and molecular responses of greater amberjack to salinity are unclear. This study reared greater amberjack juveniles under different salinity stresses (40, 30, 20, and 10 ppt) for 30 days to assess their tolerance, adaptation, and molecular responses to salinity. RNA sequencing analysis of gill tissue was used to identify genes and biological processes involved in greater amberjack response to salinity stress at 40, 30, and 20 ppt. Eighteen differentially expressed genes (DEGs) (nine upregulated and nine downregulated) were identified in the 40 vs. 30 ppt group. Moreover, 417 DEGs (205 up-regulated and 212 down-regulated) were identified in the 20 vs. 30 ppt group. qPCR and transcriptomic analysis indicated that salinity stress affected the expression of genes involved in steroid biosynthesis (ebp, sqle, lss, dhcr7, dhcr24, and cyp51a1), lipid metabolism (msmo1, nsdhl, ogdh, and edar), ion transporters (slc25a48, slc37a4, slc44a4, and apq4), and immune response (wnt4 and tlr5). Furthermore, KEGG pathway enrichment analysis showed that the DEGs were enriched in steroid biosynthesis, lipids metabolism, cytokine-cytokine receptor interaction, tryptophan metabolism, and insulin signaling pathway. Therefore, this study provides insights into the molecular mechanisms of marine fish adaptation to salinity.

Abstract
As the basic element of aerobic animal life, oxygen participates in most physiological activities of animals. Hypoxia stress is often the subject of aquatic animal research. Macrobrachium nipponense, an economically important aquatic animal in southern China, has been affected by hypoxia for many years and this has resulted in a large amount of economic loss due to its sensitivity to hypoxia; Metabolism and transcriptome data were combined in the analysis of the hepatopancreas of M. nipponense in different physiological states under hypoxia; A total of 108, 86, and 48 differentially expressed metabolites (DEMs) were found in three different comparisons (survived, moribund, and dead shrimps), respectively. Thirty-two common DEMs were found by comparing the different physiological states of M. nipponense with the control group in response to hypoxia. Twelve hypoxia-related genes were identified by screening and analyzing common DEMs. GTP phosphoenolpyruvate carboxykinase (PEPCK) was the only differentially expressed gene that ranked highly in transcriptome analysis combined with metabolome analysis. PEPCK ranked highly both in transcriptome analysis and in combination with metabolism analysis; therefore, it was considered to have an important role in hypoxic response. This manuscript fills the one-sidedness of the gap in hypoxia transcriptome analysis and reversely deduces several new genes related to hypoxia from metabolites. This study contributes to the clarification of the molecular process associated with M. nipponense under hypoxic stress.

[PMID: 34408747 PMCID: PMC8365339 DOI: 10.3389/fimmu.2021.698697] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 07/21/2021] [Indexed: 12/17/2022] Open
Abstract
Nuclear DNA-binding TCF proteins, which act as the main downstream effectors of Wnt signaling, are essential for the regulation of cell fate and innate immunity. However, their role during viral infection in shrimp remains unknown. Herein, we demonstrated that Litopenaeus vannamei TCF (LvTcf) acts independently of Lvβ-catenin to promote interferon-like protein LvVago1 production, thus mounting the response to WSSV infection. Further, we observed that WSV083, a WSSV serine/threonine protein kinase, bound to LvTcf and phosphorylated it. Phosphorylated LvTcf was then recognized and degraded via the ubiquitin-proteasome pathway. Moreover, mass spectrometry analyses indicated that the T39 and T104 residues of LvTcf were target sites phosphorylated by WSV083. Point mutation analyses suggested that additional sites of LvTcf may undergo phosphorylation via WSV083. Taken together, the current work provides valuable insights into host immunity and viral pathogenesis. LvTcf is not only a modulator of shrimp innate immunity but is also an important target for WSSV immune evasion. Thus, the current findings will help improve disease control in shrimps.

The T cell factor, pangolin, from Litopenaeus vannamei play a positive role in the immune responses against white spot syndrome virus infection. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 119:104041. [PMID: 33577842 DOI: 10.1016/j.dci.2021.104041] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 02/03/2021] [Accepted: 02/04/2021] [Indexed: 06/12/2023]
Abstract
As a downstream interactor of β-catenin, Pangolin which is the homologous protein of the T cell factor/lymphoid enhancer factor (TCF/LEF) in vertebrates is less understood in the research field of immunity. In this study, two isoforms of Litopenaeus vannamei Pangolin (LvPangolin1 and LvPangolin2) were identified. Phylogenetic tree analysis revealed that all of the Pangolin proteins from invertebrates were represented the same lineage. The mRNA expression profiles of the LvPangolin1 and LvPangolin2 genes differed across different tissues. The expression of LvPangolin1 and the amount of LvPangolin1and LvPangolin2 combined (LvPangolinComb) were significantly increased in the haemocyte, intestine and gill but reduced in the hepatopancreas after white spot syndrome virus (WSSV) challenge. The inhibition of LvPangolin1 but not LvPangolinComb significantly reduced the survival rates of L. vannamei after WSSV infection, while significantly higher WSSV viral loads in both LvPangolin1-inhibited and LvPangolinComb-inhibited L. vannamei were observed. Knockdown of LvPangolin by RNAi could distinctly decrease the expression of antimicrobial peptide (AMP) genes and their related transcription factors. All of these results indicate that LvPangolin plays a positive role in the response to WSSV infection and that this may be mediated through regulating the immune signalling pathways which control the expression of AMPs with antiviral abilities.

The significant sex-biased expression pattern of Sp-Wnt4 provides novel insights into the ovarian development of mud crab (Scylla Paramamosain). Int J Biol Macromol 2021; 183:490-501.

Abstract
The wingless-type MMTV integration site family member-4 (Wnt4), a member of the wingless-related integration site (Wnt) family, is widely accepted as a key regulator of ovarian development in mammals. In this study, a full-length cDNA of Wnt4 (designated as Sp-Wnt4) was cloned, characterized, and functionally studied in mud crab (Scylla paramamosain). The full-length cDNA of Sp-Wnt4 consists of 2659 bp with an open reading frame (ORF) encoding 359 amino acids, a 907 bp 5'-UTR and a 672 bp 3'-UTR. Sp-Wnt4 contains 25 cysteine (Cys) residues and three potential N-glycosylation sites. Sp-Wnt4 protein shared the highest identity (98.9%) to the Wnt4 protein of Portunus trituberculatus. The phylogenetic tree showed that Sp-Wnt4 and Wnt4 protein of Malacostracan crustaceans clustered together, indicating that they had a close genetic distance. Sp-Wnt4 was expressed at a higher level in the ovary compared to other tissues, with the highest expression level at the third stage (O-III) of the ovarian development (P < 0.05). A downward trend was observed in the expression level of Sp-Wnt4 from the embryo stage to crablet stages (P < 0.05). After unilateral eyestalk ablation, the expression level of Sp-Wnt4 significantly increased in testis (14-fold) and downregulated (3.1-fold) in the gill (P < 0.05) of females. In situ hybridization (ISH) assay revealed that Sp-Wnt4 transcripts were mainly localized in the cytoplasm of oocyte cells. These findings showed that Sp-Wnt4 play crucial roles in the ovarian development of S. paramamosain. In conclusion, our study provides novel insights into the evolution and roles of the Wnt4 gene.

Abstract
Glycogen synthase kinase-3 (GSK3), a cytoplasmic serine/threonine-protein kinase involved in a large number of key cellular processes, is a little-known signaling molecule in virus study. In this study, a GSK3 protein which was highly similar to GSK3β homologs from other species in Litopenaeus vannamei (designated as LvGSK3β) was obtained. LvGSK3β was expressed constitutively in the healthy L. vannamei, at the highest level in the intestine and the lowest level in the eyestalk. White spot syndrome virus (WSSV) reduced LvGSK3β expression was in immune tissues including the hemocyte, intestine, gill and hepatopancreas. The inhibition of LvGSK3β resulted in significantly higher survival rates of L. vannamei during WSSV infection than the control group, and significantly lower WSSV viral loads in LvGSK3β-inhibited L. vannamei were observed. Knockdown of LvGSK3β by RNAi resulted in increases in the expression of LvDorsal and several NF-κB driven antimicrobial peptide (AMP) genes (including ALF, PEN and crustin), but a decrease in LvCactus expression. Accordingly, overexpression of LvGSK3β could reduce the promoter activity of LvDorsal and several AMPs, while the promoter activity of LvCactus was increased. Electrophoretic mobility shift assays (EMSA) showed that LvDorsal could bind to the promoter of LvGSK3β. The interaction between LvGSK3β and LvDorsal or LvCactus was confirmed using co-immunoprecipitation (Co-IP) assays. In addition, the expression of LvGSK3β was dramatically reduced by knockdown of LvDorsal. In summary, the results presented in this study indicated that LvGSK3β had a negative effect on L. vannamei by mediating a feedback regulation of the NF-κB pathway when it is infected by WSSV.

Abstract
The Wnt signal transduction pathway is involved in a wide variety of cellular processes, including cell proliferation, differentiation, apoptosis, and immunity against microbial infection. In the current study, we cloned and characterized two Wnt homologues (Mn-Wnt4 and Mn-Wnt16) in Macrobrachium nipponense. The full length cDNA of Mn-Wnt4 was 3144 bp with a 1074 bp open reading frame (ORF) that encoded a protein containing 358 amino acid residues. The full length cDNA of Mn-Wnt16 transcript was 2893 bp with a 1281 bp ORF that encoded a 427 amino acid protein. Mn-Wnt4 and Mn-Wnt16 proteins contained a highly conserved WNT1 domain. Tissue distribution analysis showed that Mn-Wnt4 and Mn-Wnt16 were highly expressed in the stomach. The transcriptional levels of Mn-Wnt4 and Mn-Wnt16 in the stomach were upregulated at most tested time points after bacterial (Staphylococcus aureus and Vibrio parahaemolyticus) and viral (White spot syndrome virus) infection. Moreover, the expression levels of some antimicrobial peptides (AMPs) (including anti-lipopolysaccharide factor [ALF] and crustin [CRU]) were upregulated after V. parahaemolyticus infection. We further used dsRNA-mediated RNA interference technology to explore the relationship between these two Wnt genes and the expression levels of AMPs during V. parahaemolyticus infection. Mn-Wnt4 knockdown could significantly inhibit the expression of ALF1 and CRU4 in the stomach of V. parahaemolyticus-injected prawns, whereas Mn-Wnt16 silencing could result in the inhibition of the expression level of CRU3 and CRU4 in the stomach of V. parahaemolyticus-infected prawns. These findings indicated that the Wnt gene family might participate in the body's innate immune response to Vibrio infection by regulating the synthesis of a variety of AMPs. Our study will help to understand the role of the Wnt signaling pathway in the immune response of crustaceans.

Abstract
Armadillo repeat-containing proteins (ARMCs) comprise a large family that is widely distributed in eukaryotes and plays prominent roles in cell-cell adhesion, intracellular signaling, and cytoskeletal regulation. In this study, three ARMC genes, termed LvARMC6, LvARMC7 and LvARMC8, were identified and characterized from Litopenaeus vannamei. The complete cDNAs open reading frames (ORF) of LvARMC6, LvARMC7, and LvARMC8 (GenBank accession no. MG735126, MG728109 and KX058562) were 1410 bp, 570 bp and 2046 bp, encoding 469, 189, and 681 amino acids, respectively. Topology analysis indicated that three ARM domains were present in LvARMC6, one in LvARMC7 and six in LvARMC8. The identities of all the three LvARMCs with other species were between 50% and 71%. Phylogenetic analysis illustrated that different subtype of ARMCs formed their own separate branches and LvARMCs were placed in branch of invertebrates respectively with strong bootstrap support. The constitutive expressions of LvARMCs were confirmed by real-time quantitative PCR. LvARMC6, LvARMC7 and LvARMC8 were expressed highest in heart, gills and epithelium, respectively. After challenge with either white spot syndrome virus (WSSV), Vibrio parahemolyticus, or Staphylococcus aureus, all of the LvARMCs demonstrated differential expression profiles in hemocytes, hepatopancreas, intestine and gills. Taken together, our results suggest that LvARMCs may play a role in the innate immune defense against pathogenic viral and bacterial infections of L. vannamei.

Abstract
Wnt signaling plays important roles in a variety of developmental and pathological processes. Here we show that Wntless, the main regulator for Wnt secretion, is involved in the innate immune response of the giant freshwater prawn, Macrobrachium rosenbergii. The full-length cDNA of the prawn Wntless (named MrWntless) is 2173 bp in length and contains a 1602-bp open reading frame (ORF), which is conceptually translated into a 533-amino acids sequence. MrWntless protein contains a highly conserved Wnt-binding domain which is required for secretion of Wnt ligands, and exhibits 57-67% identity with known Wntless proteins of other animals. MrWntless was found to be expressed in a variety of prawn tissues including heart, gill, muscle, gut, hepatopancreas and ovary. Moreover, MrWntless expression was significantly increased in the hepatopancreas and gill of the prawns challenged by the bacterial pathogen Aeromonas hydrophila and Vibrio parahaemolyticus. Knockdown of MrWntless by RNA interference in prawns led to dramatically decreased MrWntless expression of approximately 70%. Furthermore, the cumulative mortality rate of the prawn injected with MrWntless dsRNA was greatly increased in response to A. hydrophila challenge compared with the control prawns. Taken together, we provide evidence that prawn Wntless is important for their innate immune response against bacterial pathogens.

Abstract
The Wnt gene family encodes secreted glycoproteins involved in a wide variety of biological processes, including embryo development, cell proliferation and differentiation, and tissue regeneration. The Wnt pathway exists in all metazoan animals, however, the relevant research is rare in crustaceans. Here we described 12 Wnt genes representing 12 Wnt gene subfamilies in the Pacific white shrimp, Litopenaeus vannamei. Based on homolog annotations and phylogenetic analyses, we named these 12 Wnt genes as LvWnt1, LvWnt2, LvWnt4-11, LvWnt16, and LvWntA. All the corresponding LvWnt proteins shared a conserved Wnt1 domain and 22 conserved cysteine residues. LvWnt1 and LvWnt6 were adjacent in a scaffold in the shrimp genome. Furthermore, we performed expression analyses of LvWnt genes at different developmental stages, during the molting process, in different tissues and after different pathogenic infection. We showed that each LvWnt gene had a unique expression pattern at different developmental stages but only a few of them expressed in adult shrimp. All the investigated LvWnt genes were initially expressed at the gastrula or limb bud embryo stages. Among them, LvWnt8 was specifically high expressed only in early embryos. LvWntA and LvWnt5 displayed high and similar expression profiles during the molting process, and LvWnt6 and LvWnt16 were specifically expressed in the thoracic ganglion, ventral nerve, intestines and gill tissues, respectively. We also found the expression of LvWntA, LvWnt5, LvWnt6, LvWnt9, and LvWnt16 were varied in the different tissues after infected with Staphylococcus aureus, Vibrio parahaemolyticus and white spot syndrome virus (WSSV), which indicated that they might participate in immune response in L. vannamei. This study provided an insight into the repertoire of the Wnt gene structure and expression in shrimps, and furthermore, might promote the understanding of development, growth and immune response of shrimps and crustaceans.

Abstract
The Wnt signaling mediated by Wnt proteins that orchestrate and influence a myriad of cellular processes, such as cell proliferation, differentiation, tumorigenesis, apoptosis, and participation in immune defense during microbe infection. Wnt5b is one of the Wnt signaling molecules that initiate the cascade. In this study, we cloned and characterized a Wnt5b homolog from Litopenaeus vannamei designed as LvWnt5b. The full length of LvWnt5b transcript was 1726 bp with an 1107 bp open reading frame that encoded a 368 aa protein, which contained 24 discontinuous and highly conserved cysteine. Real-time quantitative PCR showed that the transcriptional level of LvWnt5b was down-regulated when infected with white spot syndrome virus (WSSV). Knock-down of LvWnt5b resulted in inhibition of the transcriptional level of WSSV gene ie1, indicating that LvWnt5b mediated signaling pathway may play an important role in defense against WSSV infection. When LvWnt5b was silenced, caspase3/7 activity in hemocytes was increased significantly, and the transcription of viral gene was decreased as well. Moreover, overexpression of LvWnt5b in HEK293T cells led to inhibition of caspase3/7 activity, which further proved the role of LvWnt5b in restraining apoptosis. The study showed that the shrimp may decrease the expression of LvWnt5b initiatively to act as an immune defense mechanism against WSSV infection via promoting apoptosis. It will be helpful for understanding the function of Wnt signaling pathway in virus invasion and host defense.
