Molecular characterization, cytoprotective, DNA protective, and immunological assessment of peroxiredoxin-1 (Prdx1) from yellowtail clownfish (Amphiprion clarkii). DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2024; 156:105175. [PMID: 38574831 DOI: 10.1016/j.dci.2024.105175] [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: 11/14/2023] [Revised: 04/01/2024] [Accepted: 04/01/2024] [Indexed: 04/06/2024]
Abstract
Peroxiredoxin-1 (Prdx1) is a thiol-specific antioxidant enzyme that detoxifies reactive oxygen species (ROS) and regulates the redox status of cells. In this study, the Prdx1 cDNA sequence was isolated from the pre-established Amphiprion clarkii (A. clarkii) (AcPrdx1) transcriptome database and characterized structurally and functionally. The AcPrdx1 coding sequence comprises 597 bp and encodes 198 amino acids with a molecular weight of 22.1 kDa and a predicted theoretical isoelectric point of 6.3. AcPrdx1 is localized and functionally available in the cytoplasm and nucleus of cells. The TXN domain of AcPrdx1 comprises two peroxiredoxin signature VCP motifs, which contain catalytic peroxidatic (Cp-C52) and resolving cysteine (CR-C173) residues. The constructed phylogenetic tree and sequence alignment revealed that AcPrdx1 is evolutionarily conserved, and its most closely related counterpart is Amphiprion ocellaris. Under normal physiological conditions, AcPrdx1 was ubiquitously detected in all tissues examined, with the most robust expression in the spleen. Furthermore, AcPrdx1 transcripts were significantly upregulated in the spleen, head kidney, and blood after immune stimulation by polyinosinic:polycytidylic acid (poly (I:C)), lipopolysaccharide (LPS), and Vibrio harveyi injection. Recombinant AcPrdx1 (rAcPrdx1) demonstrated antioxidant and DNA protective properties in a concentration-dependent manner, as evidenced by insulin disulfide reduction, peroxidase activity, and metal-catalyzed oxidation (MCO) assays, whereas cells transfected with pcDNA3.1(+)/AcPrdx1 showed significant cytoprotective function under oxidative and nitrosative stress. Overexpression of AcPrdx1 in fathead minnow (FHM) cells led to a lower viral copy number following viral hemorrhagic septicemia virus (VHSV) infection, along with upregulation of several antiviral genes. Collectively, this study provides insights into the function of AcPrdx1 in defense against oxidative stressors and its role in the immune response against pathogenic infections in A. clarkii.

Liu Z, Huang Y, Chen H, Liu C, Wang M, Bian C, Wang L, Song L. Chromosome-level genome assembly of the deep-sea snail Phymorhynchus buccinoides provides insights into the adaptation to the cold seep habitat. BMC Genomics 2023; 24:679. [PMID: 37950158 PMCID: PMC10638732 DOI: 10.1186/s12864-023-09760-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 10/22/2023] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND The deep-sea snail Phymorhynchus buccinoides belongs to the genus Phymorhynchus (Neogastropoda: Raphitomidae), and it is a dominant specie in the cold seep habitat. As the environment of the cold seep is characterized by darkness, hypoxia and high concentrations of toxic substances such as hydrogen sulfide (H2S), exploration of the diverse fauna living around cold seeps will help to uncover the adaptive mechanisms to this unique habitat. In the present study, a chromosome-level genome of P. buccinoides was constructed and a series of genomic and transcriptomic analyses were conducted to explore its molecular adaptation mechanisms to the cold seep environments. RESULTS The assembled genome size of the P. buccinoides was approximately 2.1 Gb, which is larger than most of the reported snail genomes, possibly due to the high proportion of repetitive elements. About 92.0% of the assembled base pairs of contigs were anchored to 34 pseudo-chromosomes with a scaffold N50 size of 60.0 Mb. Compared with relative specie in the shallow water, the glutamate regulative and related genes were expanded in P. buccinoides, which contributes to the acclimation to hypoxia and coldness. Besides, the relatively high mRNA expression levels of the olfactory/chemosensory genes in osphradium indicate that P. buccinoides might have evolved a highly developed and sensitive olfactory organ for its orientation and predation. Moreover, the genome and transcriptome analyses demonstrate that P. buccinoides has evolved a sulfite-tolerance mechanism by performing H2S detoxification. Many genes involved in H2S detoxification were highly expressed in ctenidium and hepatopancreas, suggesting that these tissues might be critical for H2S detoxification and sulfite tolerance. CONCLUSIONS In summary, our report of this chromosome-level deep-sea snail genome provides a comprehensive genomic basis for the understanding of the adaptation strategy of P. buccinoides to the extreme environment at the deep-sea cold seeps.

Abstract
Cristaria plicata is one of the more important freshwater pearl bivalves in China, which is susceptible to pathogen infection, and greatly impacts the ability of breeding pearls. Nrf2/ARE signaling pathway and its downstream target gene Prx5 have endogenous antioxidant functions to protect cells from oxidative damage. The full-length cDNA of Prx5 was cloned from C. Plicata, which was 1420 bp, encoding a total of 189 amino acids and had two conserved cysteine residues (Cys78 and Cys179). The amino acid sequence of CpPrx5 was highly similar to Prx5 of other species. Real-time fluorescence quantitative PCR showed that CpPrx5 was distributed in various tissues of mussels, and the highest expression was in hepatopancreas. The expression of CpPrx5 up-regulated in hepatopancreas and gills after LPS, PGN and Poly:I:C stimulation. The recombinant plasmid DE3-PGEX-4T-1-CpPrx5 was expressed in Escherichia coli BL21 and showed antioxidant activity. With the increase of CpPrx5 protein concentration, the superhelical form of DNA was protected. The expression of CpPrx5 was up-regulated after interference CpKeap1 and down-regulated after interference CpNrf2. Gel block assay showed that CpNrf2 and CpMafK proteins blocked CpPrx5 promoter. Subcellular localization showed that CpPrx5 was located in 293T nucleus and cytoplasm and CpMafK was located in 293T nucleus. GST-Pull down verified that CpMafK and CpPrx5 could bind in vitro. These results indicated that Prx5 had antioxidant function and could protects DNA from oxidative damage, and participated in transcriptional regulation by combining with the transcription factor MafK. In addition, MafK could combine with Nrf2 to regulate the downstream target gene Prx5.

FISH AND SHELLFISH IMMUNOLOGY REPORTS 2023; 4:100081.

Abstract
Peroxiredoxins (Prxs) widely exist in organisms and can prevent oxidative damage. Here, the characterization and biological function of NdPrx3 from Neocaridina denticulata sinensis were analyzed. The coding sequence of NdPrx3 consists of 684 bp open reading frame (ORF), encoding 227 amino acids with a predicted molecular weight of 24.7 kDa and theoretical pI 6.49. Multiple sequence alignments showed that the conserved domains of NdPrx3, including catalytic triad, dimer interface, decamer interface, peroxidatic, and resolving cysteines, were similar to those of other organisms. The phylogenetic relationship demonstrated that NdPrx3 clustered in the Prx3 class. The highest relative expression of NdPrx3 mRNA was confirmed in gill among the nine tissues from healthy shrimp. The transcript level of NdPrx3 was significantly upregulated from 0 h to 48 h and decreased in 72 h under copper challenge, indicating that NdPrx3 may play an important role in the copper challenge of N. denticulata sinensis. In addition, NdPrx3 was recombinantly expressed in E. coli and purified to one band on SDS-PAGE. The DNA protection of rNdPrx3 was verified. The enzymatic assay of the recombinant NdPrx3 indicated that it had the oxidoreductase function and was stable at a low temperature (10-30 °C).

Abstract
Abstract
Background
The deep-sea mussel Gigantidas haimaensis is a representative species from the Haima cold seep ecosystem in the South China Sea that establishes endosymbiosis with chemotrophic bacteria. During long-term evolution, G. haimaensis has adapted well to the local environment of cold seeps. Until now, adaptive mechanisms responding to environmental stresses have remained poorly understood.
Results
In this study, transcriptomic analysis was performed for muscle tissue of G. haimaensis in the in situ environment (MH) and laboratory environment for 0 h (M0), 3 h (M3) and 9 h (M9), and 187,368 transcript sequences and 22,924 annotated differentially expressed genes (DEGs) were generated. Based on Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, these DEGs were enriched with a broad spectrum of biological processes and pathways, including those associated with antioxidants, apoptosis, chaperones, immunity and metabolism. Among these significantly enriched pathways, protein processing in the endoplasmic reticulum and metabolism were the most affected metabolic pathways. These results may imply that G. haimaensis struggles to support the life response to environmental change by changing gene expression profiles.
Conclusion
The present study provides a better understanding of the biological responses and survival strategies of the mussel G. haimaensis from deep sea in situ to the laboratory environment.

Abstract
Neospora caninum, an apicomplexan parasite, is the etiological agent of neosporosis, a disease that leads to neurological symptoms in dogs and abortion in cattle. Vaccine or drug treatments for neosporosis remain to be determined. Therefore, it is of undeniable relevance to investigate new molecules involved in the parasite's successful survival within the host cell. The aim of this study was to characterize the N. caninum peroxiredoxin (NcPrx), an enzyme involved in the redox system of the parasite. The NcPrx amino acid sequence showed high identity and similarity compared to homologues representatives of Apicomplexa phylum. The recombinant NcPrx (rNcPrx) was cloned and expressed in Escherichia coli (BL21) with the predicted molecular weight (22 kDa), and the identity of monomer and dimer forms of rNcPrx was confirmed by mass spectrometry. Native and recombinant NcPrx were detected by ELISA and western blot, using the polyclonal anti-rNcPrx serum. Multiphoton analysis showed that NcPrx is localized in tachyzoite cytosol. H2O2 treatment increased the rNcPrx dimerization in vitro, and associated with the in silico data, we suggest that NcPrx belongs to typical 2-Cys Prx group (AhpC/Prx1 family). rNcPrx also increased the H2O2 clearance and protected plasmidial DNA under oxidative conditions. Finally, H2O2 increased the NcPrx dimerization in intracellular and extracellular tachyzoites suggesting that it is enrolled in H2O2 clearance and sensing in N. caninum.

Abstract
Toll-like receptors (TLRs)are pattern recognition receptors (PRRs) that are important in invertebrate innate immunity for the recognition and elimination of pathogens. Although they were reported in many fishes, Toll-like receptors subfamily contain a large number of members with different functions that need to research in deep. In the present study, the full-length cDNA of TLR3 from the golden pompano, Trachinotus ovatus, was cloned and characterized. The full length of ToTLR3 cDNA was 3710 bp including an open reading frame of 2760 bp encoding a peptide of 919 amino acids. The derived amino acids sequence comprised of 14 leucine-rich repeats (LRR), capped with LRRCT followed by transmembrane domain and cytoplasmic Toll/IL-1R domain (TIR). Multiple sequence alignment and phylogenetic analysis revealed that ToTLR3 shared the highest similarity to the teleost fish and suggested ToTLR3 is fairly conservative in evolution process. Tissues distribution analysis indicated that ToTLR3 showed a tissue-specific variation with high expression in blood and liver. After the fish were stimulated by poly(I:C), flagellin and LPS, ToTLR3 expression in the liver, intestine, blood, kidney, skin and muscle was significantly upregulated in a time-depended manner, especially in immune related tissues such as liver, blood and kidney. Binding assay revealed the specificity of rToTLR3 for pathogen-associated molecular patterns (PAMPs) and bacteria that included Vibrio harveyi, V. vulnificus, V. anguillarum, Photobacterium damselae, Escherichia coli, Aeromonas hydrophila, Staphylococcus aureus and PolyI:C, LPS, Flagellin, and PGN. In addition, a luciferase reporter assay showed that overexpression ToTLR3 significantly increased NF-κB activity. Collectively, our results suggested that ToTLR3 might play an important role as a pattern recognition receptor (PRR) in the immune response towards pathogen infections, and transmiss the danger signal to downstream signaling pathways.

Abstract
Peroxiredoxins (Prxs) are ubiquitously expressed antioxidant proteins that can protect aerobic organisms from oxidative stress. Here, we characterized the HaPrx3 homolog at the molecular level from big-belly seahorse (Hippocampus abdominalis) and analyzed its functional activities. The coding sequence of HaPrx3 consists of 726 bp, which encodes 241 amino acids. The predicted molecular weight and theoretical isoelectric point (pI) of HaPrx3 was 26.20 kDa and 7.04, respectively. Multiple sequence alignments revealed that the arrangements of domains, catalytic triads, dimers, and decamer interfaces of HaPrx3 were conserved among Prx sequences of other organisms. According to the phylogenetic analysis, HaPrx3 is clustered with the teleost Prx3 subclade. The highest transcript level of HaPrx3 was detected in the ovary tissue among fourteen healthy fish tissues. The mRNA levels of HaPrx3 in blood and liver tissues were significantly (P < 0.05) upregulated in response to lipopolysaccharide (LPS), polyinosinic-polycytidylic (poly I:C), Edwardsiella tarda, and Streptococcus iniae, suggesting its involvement in immune responses. Under functional properties, insulin disulfide reduction assay confirmed the oxidoreductase activity of recombinant HaPrx3. A cell viability assay and Hoechst staining indicated cell survival ability and reduction of apoptotic activity, respectively. Moreover, a peroxidase activity assay verified peroxidase activity, while a metal-catalyzed oxidation (MCO) assay indicated the DNA protection ability of HaPrx3. Collectively, it is concluded that HaPrx3 may play a significant role in oxidative stress and immune responses against pathogenic infections in big-belly seahorses.

Abstract
Carotenoids are biologically active pigments that are well-known to enhance the defense and immunity of the vertebrate system. However, in invertebrates, the role of carotenoids in immunity is not clear. Therefore, this study aims to review the scientific evidence for the role of carotenoids in invertebrate immunization. From the analysis of published literatures and recent studies from our laboratory, it is obvious that carotenoids are involved in invertebrate immunity in two ways. On the one hand, carotenoids can act as antioxidant enzymes to remove singlet oxygen, superoxide anion radicals, and hydroxyl radicals, thereby reducing SOD activity and reducing the cost of immunity. In some organisms, carotenoids have been shown to promote SOD activity by up-regulating the expression of the ZnCuSOD gene. Carotenoids, on the other hand, play a role in the expression and regulation of many genes involved in invertebrate immunity, including thioredoxins (TRX), peptidoglycan recognition receptor proteins (PGRPs), ferritins, prophenoloxidase (ProPO), vitellogenin (Vg), toll-like receptor (TLRs), heat shock proteins (HSPs), and CuZnSOD gene. The information in this review is very useful for updating our understanding of the progress of carotenoid research in invertebrate immunology and to help identify topics for future topics.

Abstract
To study the effects of Bacillus lincheniformis feeding frequency on the survival and growth of Haliotis discus hannai abalone, we measured the expression levels of nonspecific immune genes and monitored the anti-Vibrio parahaemolyticus immune reaction. H. discus hannai (shell length: 32.75 ± 2.63 mm, body weight: 4.91 ± 0.34 g) was selected to perform a 70 d laboratory culture experiment including a 14 d V. parahaemolyticus artificial infection experiment. The control group (C) was fed normal commercial feed every day. The M1 experimental group was given experimental feed and basal feed on alternating days until the end of the experiment. The M2 experimental group was given experimental feed for 4 d and basal feed for 3 d, and this cycle was repeated every 7 d until the end of the experiment. The M3 experimental group was given experimental feed for 2 d and basal feed for 5 d, and this cycle was repeated every 7 d until the end of the experiment. The M4 group was continuously given experimental feed for the duration of the experiment. The concentration of added B. lincheniformis in each experimental group was 105 cfu/g (according to the quantity of viable bacteria). The specific growth rate (as measured by body weight) and the feed conversion efficiency of the abalone in M1 and M2 were significantly higher than those in M4 and C (P < 0.05). The cellulose and lipase activities of abalone in M1, M2 or M4 were significantly higher than those in M3 or C (P < 0.05). The acid phosphatase, superoxide dismutase, total haemocyte counts, O2- levels generated by respiratory bursts, and the expression levels of Mn-SOD, TPx, GSTs and GSTm in abalone in the M2 group were significantly higher than those in any other feeding frequency group (P < 0.05). At the end of the V. parahaemolyticus infection, the cumulative mortality of the abalone in M2 was significantly lower than that in any other group (P < 0.05). Consequently, given the growth advantages and the enhancement of immune function, the feeding plan in which B. lincheniformis was applied for 4 d per week, and basal feed was then applied for 3 d, did not lead to a high level of immune reaction, immune fatigue or waste of resources, but increased the growth rate of individuals and their resistance to V. parahaemolyticus infection.

FISH & SHELLFISH IMMUNOLOGY 2019; 94:617-627. [PMID: 31465875 DOI: 10.1016/j.fsi.2019.08.067] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2019] [Revised: 08/23/2019] [Accepted: 08/26/2019] [Indexed: 06/10/2023]
Abstract
The effects of a diet containing the probiotic Bacillus amyloliquefaciens on the survival and growth of Haliotis discus hannai were evaluated by measuring growth and hematological parameters and the expression levels of nonspecific immune genes. In addition, the abalone's response to Vibrio parahaemolyticus infection was assessed. H. discus hannai (shell length: 29.35 ± 1.81 mm, body weight: 4.28 ± 0.23 g) were exposed to an 8-week culture experiment in indoor aquariums and a 2-week V. parahaemolyticus artificial infection experiment. In each experiment, the control group (C) was fed daily with the basal feed; the experimental groups were fed daily with the experimental feed, prepared by spraying B. amyloliquefaciens onto the basal feed at final concentrations of 103 (group A1), 105 (A2), and 107 (A3) cfu/g. The survival rate, body weight specific growth rate, and food conversion efficiency in A2 and A3 were significantly higher than those in A1 and C (P < 0.05). The total number of blood lymphocytes, the O2- and NO levels produced from respiratory burst, the activities of acid phosphatase, superoxide dismutase, and catalase, and the expression levels of catalase and thiol peroxidase in A2 were not significantly different from those in A3, but these factors were significantly higher in A2 compared to A1 and C (P < 0.05). The total antioxidant capacity and expression levels of glutathione S-transferase in A1, A2 and A3 were significantly higher than those in C (P < 0.05). At day 9 after infection with V. parahaemolyticus, all abalone in C were dead; at the end of the experiment, the cumulative mortality of abalone in A2 was significantly lower than that in any other group (P < 0.05). Thus, the experimental feed containing 105 cfu/g B. amyloliquefaciens not only facilitated the food intake and growth of abalone, but also effectively enhanced their non-specific immunity and resistance to V. parahaemolyticus infection. In this regard, B. amyloliquefaciens may be a useful probiotic strain for abalone aquaculture.

Molecular insights of a novel cephalopod toll-like receptor homologue in Sepiella japonica, revealing its function under the stress of aquatic pathogenic bacteria. FISH & SHELLFISH IMMUNOLOGY 2019; 90:297-307. [PMID: 31059811 DOI: 10.1016/j.fsi.2019.05.004] [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: 02/27/2019] [Revised: 05/01/2019] [Accepted: 05/03/2019] [Indexed: 06/09/2023]
Abstract
Toll-like receptors (TLRs) play an important role in defense response to pathogens in mollusk. In this study the first TLR from Sepiella japonica (named as SjTLR) was functionally characterized, and its full-length cDNA consisted of 3914bp (GenBank accession no. AQY56780.1) including an open reading frame of 3582bp, encoding a putative protein of 1193 amino acids. Its theoretical molecular weight was 137.87 KDa and the predicted isoelectric point was 3.69. The derived amino acids sequence comprised of an extracellular domain including 26 amino acids signal peptide and eleven leucine-rich repeats (LRR), capped with LRRCT and LRRNT followed by transmembrane domain and cytoplasmic Toll/IL-1R domain (TIR). In addition, 12 potential N-linked glycosylation sites were present in the ectodomain to influence protein trafficking, surface presentation and ligand recognition. Multiple sequence alignment and phylogenetic analysis revealed that SjTLR shared the highest similarity to that of Euprymna scolopes and they fell into the same clade. Real-time PCR showed SjTLR expressed constitutively in all tested tissues, including gill, liver, brain, muscle, intestine, heart, lobus opticus and stomach, but showed different expression levels with genders. The highest expression was in the liver, and the lowest was in stomach for both genders. The functional domain region sequences encoding LRRs domain protein and TIR domain containing protein (TcpB) were expressed in BL21(DE3) respectively and purified with Ni-NAT Superflow resin conforming to the expected molecular weight. The cellular localization of SjTLR in HEK293 cells was conducted and plasma membrane localization was detected. SjLRRs internalization upon the activation of LPS was also observed, and dramatic redistribution of SjLRRs in the cytoplasm with distinct perinuclear accumulation was found. After SjTLR transfection Toll/NF-κB signaling pathway was active in HEK293 treated with LPS and TNFɑ. The nuclear related genes may also be activated by NF-κB in the nucleus, and the corresponding mRNA was transferred through the intracellular signal transduction pathway, so that IL-6 cytokines could be synthesized and released. After infection by Vibrio parahemolyticus and Aeromonas hydrophila the expression of SjTLR were upregulated with time-dependent manner. These findings might be valuable for understanding the innate immune signaling pathways of S.japonica and enabling future studies on host-pathogen interactions.

Abstract
Peroxiredoxin (Prx) family are known as an important antioxidant enzyme as the first line of defense against oxidative damage, and also involved in immune responses following viral and bacterial infection. Here, a full-length Prx1 cDNA sequence (CiPrx1) was cloned from grass carp (Ctenopharyngodon idella), which was 1029 bp, including a 5'-terminal untranslated region (UTR) of 121 bp, a 3'-UTR of 272 bp, an open reading frame of 600 bp encoding 199 amino acids with molecular weight of 22.21 kDa and isoelectric point of 6.30. CiPrx1 shares 80.8-99% protein sequence similarity with Prx1 of other fishes. The conserved peroxidase catalytic center "FYPLDFTFVCPTEI" and "GEVCPA" were observed in the sequence of CiPrx1; this indicated that it was a member of 2-Cys Prx. Subcellular localization of CiPrx1 was only strongly distributed in the cytoplasm. Quantitative real-time PCR (RT-qPCR) assays revealed that CiPrx1 mRNA was ubiquitously detected in all tested tissues, and the expression was comparatively high in liver, gill and spleen. Further, the expression of CiPrx1 can be induced by grass carp reovirus (GCRV), lipopolysaccharide (LPS) and polyinosinic:polycytidylic acid (Poly I:C) infection in the different tissues. Moreover, the recombinant CiPrx1 (rCiPrx1) protein was found a potential antioxidant enzyme, that could inhibit DNA damage from oxidants. Altogether, our results imply that CiPrx1 is associated with defending against virus and bacteria pathogens and oxidants in grass carp.

Abstract
Peroxiredoxins (Prxs) are a widespread and greatly transcribed family of antioxidant proteins, which rapidly detoxify peroxynitrite, hydrogen peroxide and organic hydroperoxides. The Prxs family members also modulate various physiological functions, including cell growth, differentiation, embryonic development, immune response, apoptosis, lipid metabolism, and cellular homeostasis. In mammals, the physiological functions of Prxs have extensively been studied; however, the knowledge is scanty in their counterpart, aquatic invertebrates. In recent years, substantial progress has been made in our knowledge of Prxs physiological functions in aquatic invertebrates, which has raised interest in defining the contribution of immune responses and removal of reactive oxygen species. In this review, we describe the recent knowledge on the Prxs physiological function in immune responses and DNA protection activity in aquatic invertebrates.

Abstract
The study was conducted to investigate the effect of diets containing 0, 2.5, 5, 7.5, and 10% S. platensis meal on total antioxidant capacity (TAC) and lipid peroxidation, as well as the expression of two antioxidant enzyme genes (SOD and CAT) in rainbow trout (Oncorhynchus mykiss). One hundred and eighty fish, with an average initial weight of 101 ± 8 g, were cultured for 10 weeks. At the end of experiment, lipid peroxidation significantly decreased in serum of fish fed with S. platensis and fish fed with 5, 7.5, and 10% microalgae showed a significantly lower value compared to control and 2.5%. Inclusion of 7.5 and 10% S. platensis in diet also decreased lipid peroxidation in liver. TAC significantly increased with increasing level of S. platensis. Expression level of superoxide dismutase (SOD) and catalase (CAT) genes significantly increased in the fish liver after administration of microalgae and fish fed with 10% S. platensis in diet showed the highest level compared to the other treatments. The present study reveals that inclusion of 10% S. platensis in diet can decrease oxidative stress in rainbow trout. Therefore, S. platensis can be used as potential antioxidant for fish farming.

Abstract
Members of Prx family function as an important players in host defense against oxidative stress, and modulate immune responses. In the current study, two complete Prx sequences were isolated from bivalve Anodonta woodiana and respectively named AwPrx4a and AwPrx4b. Regulative characterizations of AwPrx4a and AwPrx4b derived from perfluorooctanesulfonate (PFOS), perfluoroocanoic acid (PFOA), lipopolysaccharide (LPS) and polyinosinic:polycytidylic (Poly I:C) challenge in hepatopancreas, gill and hemocytes were measured by quantitative real-time PCR, respectively. The full-length cDNA of AwPrx4a had an open reading frame ORF of 588 bp encoding 196 amino acids. Two highly conserved Prxs signature motifs were observed in deduced amino acid sequence, one was FYPLDFTFACPTEI, and the other was GEVCPA. Complete cDNA sequence of AwPrx4b was comprised of a 5' untranslated region (UTR) of 120 nucleotides, a 426 bp ORF which was encoded 142 amino acids, and a long 3'-UTR of 412 nucleotides. Expressions of AwPrx4a and AwPrx4b showed a significant up-regulation pattern in groups at lower concentration treatment of PFOS and PFOA, a biphasic profile in groups with a higher concentration treatment. Compared with that of control group, expressions of AwPrx4a and AwPrx4b were significantly induced by LPS and Poly I:C treatment in the hepatopancreas, gill and hemocytes. These results indicate up-regulations of AwPrx4a and AwPrx4b expression are associated with eliminating oxidative stress derived from PFOS and PFOA administration as well as enhancing immune defense against LPS and Poly I:C challenge.

Stefani F, Casatta N, Ferrarin C, Izzotti A, Maicu F, Viganò L. Gene expression and genotoxicity in Manila clam (Ruditapes philippinarum) modulated by sediment contamination and lagoon dynamics in the Po river delta. MARINE ENVIRONMENTAL RESEARCH 2018; 142:257-274. [PMID: 30389237 DOI: 10.1016/j.marenvres.2018.10.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Revised: 09/18/2018] [Accepted: 10/18/2018] [Indexed: 06/08/2023]
Abstract
The lagoons of the Po River delta are potentially exposed to complex mixtures of contaminants, nevertheless, there is a substantial lack of information about the biological effects of these contaminants in the Po delta lagoons. These environments are highly dynamic and the interactions between chemical and environmental stressors could prevent the proper identification of biological effects and their causes. In this study, we aimed to disentangle such interactions focusing on Manila clams, previously exposed to six lagoons of the Po delta, adopting three complementary tools: a) the detailed description via modelling techniques of lagoon dynamics for salinity and water temperature; b) the response sensitivity of a number of target genes (ahr, cyp4, ρ-gst, σ-gst, hsp22, hsp70, hsp90, ikb, dbh, ach, cat, Mn-sod, Cu/Zn-sod, cyp-a, flp, grx, TrxP) investigated in clam digestive glands by Real Time PCR; and c) the relevance of DNA adducts determined in clams as markers of exposure to genotoxic chemicals. The lagoons showed specific dynamics, and two of them (Marinetta and Canarin) could induce osmotic stress. A group of genes (ahr, cyp4, Mn-sod, σ-gst, hsp-22, cyp-a, TrxP) seemed to be associated with overall lagoon characteristics as may be described by salinity and its variations. Lagoon modelling and a second group of genes (hsp70, hsp90, cat, ikb, ach, grx, Cu/Zn-sod) also suggested that moderate increases of river discharge may imply worse exposure conditions. Oxidative stress seemed to be associated with such events but it was slightly evident also under normal exposure conditions. DNA adduct formation was mainly associated with overwhelmed antioxidant defences (e.g. low Cu/Zn-sod) or seemingly with their lack of response in due time. In Po delta lagoons, Manila clam can be affected by chemical and environmental factors which can contribute to induce oxidative stress, DNA adduct formation and, ultimately, to affect clam condition and health.

FISH & SHELLFISH IMMUNOLOGY 2018; 78:42-51. [PMID: 29626669 DOI: 10.1016/j.fsi.2018.04.010] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2017] [Revised: 03/26/2018] [Accepted: 04/03/2018] [Indexed: 06/08/2023]
Abstract
To study the effects of probiotic-added food on the survival and growth of abalone (Haliotis discus hannai Ino), the expression levels of nonspecific immune genes and the anti-Vibrio parahaemolyticus infection were examined. During an 8-week culturing experiment in an indoor aquarium and a 2-week V. parahaemolyticus artificial infection experiment, the control group was fed with untreated food once a day, while the experimental groups (L1, L2 and L3) were fed with Lactobacillus pentosus added food. The concentration of probiotics in the experimental food was 103 cfu/g (L1), 105 cfu/g (L2) and 107 cfu/g (L3), respectively. The results showed that the survival rate, shell length-specific growth rate, and the food conversion rate (FCR) of abalones in L1 and L2 were significantly higher than the control group. The food intake of abalones in L3 was significantly lower than that in L1, L2 and the control group, but there was no significant difference in FCR identified between L1, L2 and L3. In the L. pentosus-added groups, the total number of blood lymphocytes, lysozyme activity, acid phosphatase, superoxide dismutase, and expression levels of Mn-superoxide dismutase (Mn-SOD) and thioredoxin peroxidase (TPx) were significantly higher than the control group, while the malondialdehyde (MDA) content was significantly lower than the control group. The phagocytic activity of blood lymphocytes, catalase activity and the expression levels of heat shock protein 70 (HSP70) of abalones in the control group were significantly lower than that in L1 and L2, but there was no significant difference when compared with L3. The levels of O2-, NO produced by respiratory burst of blood lymphocytes and the expression levels of catalase (CAT) in L1 and L2 were significantly higher than both L3 and the control group. Seven days after infection with V. parahaemolyticus, all abalones in the control group were dead. After 14 days the cumulative mortality rate of abalones in the L. pentosus-added groups was significantly lower than that in the control group. Therefore, the 103 cfu/g and 105 cfu/g L. pentosus-added food not only promoted food intake and growth of abalones, but also improved their non-specific immunity and reduced V. parahaemolyticus infection, indicating that this strain is a good potential candidate for probiotic added food in the aquaculture industry.

Abstract
Toll-like receptor (TLR) is considered to be an evolutionarily conserved transmembrane protein which promotes the Toll signal pathway to active the expression of transcription factors in the innate immunity of the organism. In this study, a full length of TLR homologue of 2525bp in Mytilus coruscus (named as McTLR-a, GenBank accession no: KY940571) was characterized. Its ORF was 1815 bp with a 5'untranslated region (UTR) of 128 bp and a 3'UTR of 582 bp, encoding 602 amino acid residues with a calculated molecular weight of 70.870 kDa (pI = 6.10). BLASTn analysis and phylogenetic relationship strongly suggested that this cDNA sequence was a member of TLR family. Quantitative real time RT-PCR showed that constitutive expression of McTLR-a was occurred, with increasing order in hemocyte, gonad, mantle, adducter, gill and hepatopancreas. Bacterial infection and heavy metals stimulation up-regulated the expression of McTLR-a mRNA in hepatopancreas with time-dependent manners. The maximum expression appeared at 12 h after pathogenic bacteria injection, with approximately 22-fold in Aeromonas hydrophila and 17-fold in Vibrio parahemolyticus higher than that of the blank group. In heavy metals stress group, they all reached peaks at 3d, while the diverse concentration caused the maximum expression were different. The highest expression reached approximately 7-fold higher than the blank in low concentration of Pb2+ exposure. In Cu2+ treated group, it reached the peak (approximately 12-fold higher than the blank)in middle concentration. These results indicated that McTLR-a might be involved in the defense response and had a significant role in mediating the environmental stress.

Abstract
To study the effects of a probiotic (Bacillus lincheniformis) on the survival and growth of Haliotis discus hannai Ino, the expression levels of nonspecific immune genes and the resistance to Vibrio parahaemolyticus infection were assessed. Abalones (shell length: 27.64 ± 1.59 mm, body weight: 4.17 ± 0.32 g) were selected for use in an 8-week culture experiment and a 2-week V. parahaemolyticus artificial infection experiment. In both experiments, the control group (C) was fed with a basal feed and the experimental groups were fed with experimental food prepared by spraying the probiotic on the basal feed at different concentrations: 103 (B1), 105 (B2), and 107 (B3) cfu/mL. The survival rate, total number of blood lymphocytes, activity of acid phosphatase, and expression level of heat shock protein 70 were significantly higher in B1, B2, and B3 than in C (P < 0.05). The specific growth rate of shell length, food intake, food conversion rate, phagocytic activity of blood lymphocytes, activities of myeloperoxidase and catalase (CAT), and expression levels of CAT and thioredoxin peroxidase of abalones in B2 were significantly higher than those in B1 and C (P < 0.05). Although the level of O2- produced by the respiratory burst of blood lymphocytes in B2 was not significantly different from those in B1 and B3, they were significantly higher than that in C (P < 0.05). The activity of superoxide dismutase (SOD), the nitric oxide levels produced by the respiratory burst of blood lymphocytes, and the expression levels of Mn-SOD in B1 and B3 were significantly higher than those in C but significantly lower than those in B2 (P < 0.05). Fourteen days after infection with V. parahaemolyticus, the cumulative mortality of abalones in B2 was significantly lower than those in B1 and C (P < 0.05). These results indicate that the food containing 105 cfu/mL Bacillus licheniformis promoted food intake and growth of abalones and also improved their resistance to V. parahaemolyticus infection. Thus, B. licheniformis is a good potential probiotic.

Abstract
Schistosomiasis japonicum is one of the most severe zoonotic diseases in China. Water buffalo and yellow cattle are important reservoir hosts and the main transmission sources of Schistosoma japonicum in endemic areas. The susceptibility of these two hosts to schistosome infection is different, as water buffaloes are less susceptible to S. japonicum than yellow cattle. In this study, iTRAQ-coupled LC-MS/MS was applied to compare the protein expression profiles of adult schistosomes recovered from water buffalo with those of yellow cattle. A total of 131 differentially expressed proteins (DEPs) were identified, including 46 upregulated proteins and 85 downregulated proteins. The iTRAQ results were confirmed by Western blotting and quantitative real-time PCR. Further analysis indicated that these DEPs were primarily involved in protein synthesis, transcriptional regulation, protein proteolysis, cytoskeletal structure and oxidative stress response processes. The results revealed that some of the differential expression molecules may affect the development and survival of schistosomes in these two natural hosts. Of note, this study provides useful information for understanding the interplay between schistosomes and their final hosts.

Abstract
Bivalves use anti-oxidative enzyme systems to defend themselves against excessive reactive oxygen species, which are often catalyzed by environmental pollution. As a key member of anti-oxidative enzyme family, catalase plays a crucial role in scavenging the high level of reactive oxygen species to protect organisms against various oxidative stresses. In this study, a catalase homologue was identified from Mytilus coruscus (named McCAT, KX957929). The open reading frame of McCAT was 1844bp with a 5' untranslated region of 341bp and a 3' untranslated region of 927bp. The deduced amino acid sequence was 512 residues in length with theoretical pI/MW 8.02/57.91kDa. BLASTn and phylogenetic analyses strongly suggested that it was a member of catalase, also known as CAT family for its conserved catalytic site motif and proximal heme-ligand signature motif. Real-time fluorescence quantitative PCR showed that constitutive expression of McCAT was occurred, with increasing order in mantle, adductor, gill, hemocyte, gonad and hepatopancreas. It was observed that bacterial infection and heavy metals stimulation up-regulated McCAT mRNA expression in hepatopancreas with time-dependent manners. The maximum expression appeared at 8h after pathogenic bacteria injecting, with 15-fold in Vibrio parahemolyticus and 60-fold in Aeromonas hydrophila than that of 0h. The highest point of McCAT mRNA appeared at different times for exposure to heavy metals with copper at day 5 (0.1mg/L 30-fold, 0.5mg/L 15-fold, 1.5mg/L 6-fold) and plumbum at day 3 (3.0mg/L 20-fold). The enzymatic activity analysis found that McCAT activity in the gill of M. coruscus was affected by heavy metals concentration. The results suggested that McCAT plays a significant role in antioxidation and the expression of McCAT can be used as a biomarker for detection of marine environmental pollution.

Abstract
Being lack of specific immune system, both enzymes and non-enzymatic antioxidants play crucial roles in immune of invertebrates. In the present study, in order to investigate immune roles of enzyme (thioredoxin, TRX) and antioxidants (carotenoids), Golden scallops with golden shell and golden muscle rich in carotenoids content and Brown scallops with brown shell and white muscle less carotenoids content of the noble scallop Chlamys nobilis were challenged by Vibrio parahaemolyticus for 48 h. Firstly, a cDNA of TRX protein gene from the scallop (named as CnTRX) was cloned and characterized. The cDNA contains 1280 bp, consisting of a 5' -UTR of 99 bp, a long 3' -UTR of 860 bp and a 321 bp open reading frame (ORF) encoding 106 amino acids. Phylogenetic analysis showed that CnTRX had a closer evolution relationship with TRX from Chlamys farreri. CnTRX was ubiquitously expressed in all examined tissues including intestine, adductor, mantle, gonad, gill, kidney, hepatopancreas and hemolymph, and the highest expression level was detected in the hemolymph. Next, CnTRX transcripts were significantly up-regulated in V. parahaemolyticus group in comparison with PBS control group. Moreover, CnTRX transcripts were significantly higher in Golden scallops than that of Brown ones at 6 h, 12 h and 24 h with bacteria challenge (P < 0.05). The present result indicates that both CnTRX and carotenoids are important factors involved in the immune defense against bacteria challenge in the noble scallop.

Abstract
Peroxiredoxins (Prxs) are ubiquitous, multifunctional and evolutionarily conserved enzymes that can protect cells from oxidative damage caused by ROS and play a vital role in immune responses. Here, a full-length Prx1 cDNA sequence (PmPrx1) was isolated from Penaeus monodon. The PmPrx1 cDNA was 951 base pairs (bp), encoding 198 amino acid polypeptides. The results of qRT-PCR showed that the PmPrx1 mRNA was ubiquitously expressed in all tissues tested and had a comparatively high expression level in immune-associated tissues (gill, hepatopancreas). To explore the immune and anti-stress roles of PmPrx1, the gills and hepatopancreas were chosen as target tissues in Penaeus monodon and were challenged with bacteria (Vibrio harveyi and Streptococcus agalactiae) and toxic environmental stresses. To further clarify the immune function of PmPrx1 after bacterial challenge, the recombinant PmPrx1 protein was acquired using a prokaryotic expression method. The antioxidant activity of the recombinant PmPrx1 was assessed by the catalyzing hydrogen peroxide assay method, and the results showed obvious antioxidant activity in a dose-dependent and temperature-dependent manner. The antimicrobial activity of purified PmPrx1 protein was evaluated and further studied in vitro relying on a bacterial growth inhibition test which was conducted in both liquid and solid cultures. Furthermore, E. coli transferred with pRSET-PmPrx1 was dramatically protected in response to metal toxicity and H2O2 oxidative stress. In summary, this study provides useful information about the role of the Prx1 gene in defense against a variety of toxic factors in shrimps that help to further clarify the functional mechanism of Prx.

Abstract
Peroxiredoxins (Prxs) play an important role against various oxidative stresses by catalyzing the reduction of hydrogen peroxide (H2O2) and organic hydroperoxides to less harmful form. A 2-cys peroxiredoxin, designated as CpPrx, was cloned from hemocytes of freshwater mussel Cristaria plicata. The full length cDNA of CpPrx is 1247 bp, which includes an open reading frame (ORF) of 591bp, encoding 196 amino acids. CpPrx possesses two conserved cysteine residues (Cys49, Cys170). The deduced amino acid sequence of CpPrx showed a high level (67-74%) of sequence similarity to 2-Cys Prxs from other species. The results of real-time quantitative PCR revealed that CpPrx mRNA was constitutively expressed in tissues, and the highest expression levels were in hepatopancreas and gills. After peptidoglycan (PGN) and Aeromonas hydrophila challenge, the expression levels of CpPrx mRNA were up-regulated in hemocytes and hepatopancreas. The cDNA of CpPrx was cloned into the plasmid pET-32, and the recombinant protein was expressed in Escherichia coli BL21(DE3). Comparison with DE3-pET-32 and DE3 strain, the cells of DE3-pET-32-CpPrx exhibited resistance to the concentration of 0.4, 0.8 and 1.2 mmoL/L H2O2 in vivo.

Abstract
As the most important disulfide bond reducates of intracellular oxidordeuctase, thioredoxin (TRX) plays a crucial role in maintaining reducing state of intracellular proteins to normally perform their function. In this study, a cDNA of TRX-like protein gene from Apostichopus japonicus (denoted as AjTRX) was cloned and characterized. The full-length cDNA of AjTRXwas of 1870 bp, consisting of a 5'-UTR of 101 bp, a long 3'-UTR of 887 bp and a 882 bp open reading frame (ORF) encoding a 293 amino acids. The predicted molecular mass and the theoretical PI of the deduced amino acids of AjTRX were 32.3 kDa and 5.52, respectively. Phylogenetic trees showed that AjTRX had a closer evolution relationship with TRX from Strongylocentrotus purpuratus. AjTRX was found to be ubiquitously expressed in all examined tissues including longitudinal muscle, coelomocytes, tube feet, intestine, respiratory tree and body wall indicating a general role in physiological processes. Temporal expression pattern of AjTRX in coelomocytes showed that AjTRX reached two peak expression levels at 8 h and 48 h after Vibrio splendidus challenge with a 8.6 and 9.3-fold increase compared to their control groups, respectively. The recombinant AjTRX protein (rAjTRX) displayed obvious antioxidant activity in a dose-dependent manner, and the higher reducing activity was detected in 20 μM experimental group. All these results strongly suggested that AjTRX could play an important role as an antioxidant in a physiological context, and might be involved in the process of bacterial challenge.

Abstract
Inefficient control of temperate abalone spawning prevents pair-wise breeding and production of abalone with highly marketable traits. Traditionally, abalone farmers have used a combination of UV irradiation and application of temperature gradients to the tank water to artificially induce spawning. Proteins are known to regulate crucial processes such as respiration, muscle contraction, feeding, growth and reproduction. Spawning as a pre-requisite of abalone reproduction is likely to be regulated, in part, by endogenous proteins. A first step in elucidating the mechanisms that regulate spawning is to identify which proteins are directly involved during spawning. The present study examined protein expression following traditional spawning induction in the Haliotis laevigata female. Gonads were collected from abalone in the following physiological states: (1) spawning; (2) post-spawning; and (3) failed-to-spawn. Differential protein abundance was initially assessed using two-dimensional difference in-gel electrophoresis coupled with mass spectrometry for protein identification. A number of reproductive proteins such as vitellogenin, vitelline envelope zona pellucida domain 29 and prohibitin, and metabolic proteins such as thioredoxin peroxidase, superoxide dismutase and heat shock proteins were identified. Differences in protein abundance levels between physiological states were further assessed using scheduled multiple reaction monitoring mass spectrometry. Positive associations were observed between the abundance of specific proteins, such as heat shock cognate 70 and peroxiredoxin 6, and the propensity or failure to spawn in abalone. These findings have contributed to better understand both the effects of oxidative and heat stress over abalone physiology and their influence on abalone spawning.

Abstract
The Chinese surf clam Mactra chinensis is an economically important bivalve species in the coastal waters of Liaoning and Shandong Province, China. In this study, we carried out transcriptome sequencing to develop molecular resources for M. chinensis and conducted an acute test of Cd(2+) stimulation through quantitative real-time PCR (qRT-PCR) to analyze the relative expression of six functional genes. A total of 100,839 transcripts and 56,712 unigenes were obtained from 39.9 million filtered reads and 21,305 unigenes were annotated by hitting against NCBI database. According to the results of qRT-PCR, heat shock protein 22 (Hsp22) and cytochrome P450 (CYP450(2C31)) were inhibited in the low concentration, and induced in the high concentration of Cd(2+); thioredoxin peroxidase (TPx-A) was at normal level in low concentration, but induced in high concentration of Cd(2+); glutathione peroxidase A (GPA), glutathione peroxidase 1 (GPA1) and Mn superoxide dismutase gene (MnSOD) were down-regulated when exposed to any treatment groups. Expression levels of the six functional genes following Cd(2+) exposure indicated that these genes were linked to environmental stress. Moreover, the present work enriched the molecule genetic data of M. chinensis.

Abstract
Glutathione S-transferases (GSTs) are the superfamily of phase II detoxification enzymes that play crucial roles in innate immunity. In this study, a pi-class GST homolog was identified from Mytilus coruscus (named as McGST1, KC525103). The full-length cDNA sequence of McGST1 was 621bp with a 5' untranslated region (UTR) of 70bp and a 3'-UTR of 201bp. The deduced amino acid sequence was 206 residues in length with theoretical pI/MW of 5.60/23.72kDa, containing the conserved G-site and diversiform H-site. BLASTn analysis and phylogenetic relationship strongly suggested that this cDNA sequence was a member of pi class GST family. The prediction of secondary structure displayed a preserved N-terminal and a C-terminal comprised with α-helixes. Quantitative real time RT-PCR showed that constitutive expression of McGST1 was occurred, with increasing order in mantle, muscle, gill, hemocyte, gonad and hepatopancreas. The stimulation of bacterial infection, heavy metals and 180CST could up-regulate McGST1 mRNA expression in hepatopancreas with time-dependent manners. The maximum expression appeared at 6h after pathogenic bacteria injected, with 10-fold in Vibrio alginolyticus and 16-fold in Vibrio harveyi higher than that of the control. The highest point of McGST1 mRNA appeared at different time for exposure to copper (10-fold at day 15), cadmium (9-fold at day10) and 180 CST (10-fold at day 15). These results suggested that McGST1 played a significant role in antioxidation and might potentially be used as indicators and biomarkers for detection of marine environmental pollution.

Abstract
Thioredoxin peroxidase (Tpx), also named peroxiredoxin (Prx), is an important peroxidase that can protect organisms against stressful environments. AccTpx4, a 1-Cys thioredoxin peroxidase gene from the Chinese honey bee Apis cerana cerana, was cloned and characterized. The AccTpx4 gene encodes a protein that is predicted to contain the conserved PVCTTE motif from 1-Cys peroxiredoxin. Quantitative real-time PCR (Q-PCR) and Western blotting revealed that AccTpx4 was induced by various oxidative stresses, such as cold, heat, insecticides, H(2)O(2), and HgCl(2). The in vivo peroxidase activity assay showed that recombinant AccTpx4 protein could efficiently degrade H(2)O(2) in the presence of DL-dithiothreitol (DTT). In addition, disc fusion assays revealed that AccTpx4 could function to protect cells against oxidative stresses. These results indicate that AccTpx4 plays an important role in oxidative stress responses and may contribute to the conservation of honeybees.

Immunoproteomic analysis of Schistosoma japonicum schistosomulum proteins recognized by immunoglobulin G in the sera of susceptible and non-susceptible hosts. J Proteomics 2015; 124:25-38.

Abstract
UNLABELLED The aim of this study was to search for immunogenic schistosomula proteins in the hope of identifying novel intervention targets. Schistosomula proteins were analyzed by immunoproteomic which the probes were sera derived from BALB/c mice (susceptible hosts) and Microtus fortis (resistant hosts). A total of 116 immunoreactive proteins recognized by 10 days post-infected BALB/c mice, M. fortis sera, and uninfected M. fortis sera were selected for further analysis. Finally, 95 protein spots were identified by mass spectrometry (MS) analysis. Bioinformatics analysis showed that the differentially identified immunogenic proteins participated mainly in cytoskeleton organization, cell motility, energy metabolism, responses to stimuli, and protein folding. Many of these proteins were the tegument or excretory-secretory products of schistosomes reported in previous studies. Among of them, Schistosoma japonicum DnaJ (Hsp40) homologue (SjDnaJ) was successfully expressed and the purified recombinant product was evaluated by immunoprotective experiment. After immunization of BALB/c mice with recombinant SjDnaJ, it could induce 34.5% and 48.9% reductions in the numbers of worms and eggs in the liver. These results contribute to a better understanding of the molecular mechanisms underlying the host-parasite relationship and provide a major dataset to facilitate the further development of new vaccine candidates and/or diagnostic markers for schistosomiasis. BIOLOGICAL SIGNIFICANCE Schistosomiasis is caused by parasitic blood-dwelling flukes in tropical and subtropical areas, and it is one of the world's most prevalent tropical diseases. The lack of effective vaccine and reliable diagnostic methods make this disease difficult to control. In China, S. japonicum can infect more than 40 different susceptible mammals for this parasite. However, M. fortis is the only known mammal where the schistosome cannot develop and it exhibits no significant pathological effects. Many studies' results showed that native antibodies against S. japonicum are present in M. fortis that may have important anti-schistosomiasis roles during the infection process. The aim of this study was to search for immunogenic schistosomula proteins in the hope of identifying novel intervention targets. We present a comparative immunoproteomics analysis of the proteins recognized by susceptible and resistant host antibodies before and 10-days after infections. The results of this analysis will be helpful for identifying the key molecules required for the survival and development of schistosomes. At the same time, the study contributes to a better understanding of the molecular mechanisms underlying the host-parasite relationship associated with schistosomes and they also provide a major dataset to facilitate the further development of new diagnostic assays and/or vaccine candidates for schistosomiasis.

Abstract
We first identified and characterized a novel peroxiredoxin (Prx), designated as CcPrx4, from the cDNA library of the tentacle of the jellyfish Cyanea capillata. The full-length cDNA sequence of CcPrx4 consisted of 884 nucleotides with an open reading frame encoding a mature protein of 247 amino acids. It showed a significant homology to peroxiredoxin 4 (Prx4) with the highly conserved F-motif (93FTFVCPTEI101), hydrophobic region (217VCPAGW222), 140GGLG143 and 239YF240, indicating that it should be a new member of the Prx4 family. The deduced CcPrx4 protein had a calculated molecular mass of 27.2 kDa and an estimated isoelectric point of 6.3. Quantitative real-time PCR analysis showed that CcPrx4 mRNA could be detected in all the jellyfish tissues analyzed. CcPrx4 protein was cloned into the expression vector, pET-24a, and expressed in Escherichia coli Rosetta (DE3) pLysS. Recombinant CcPrx4 protein was purified by HisTrap High Performance chelating column chromatography and analyzed for its biological function. The results showed that the purified recombinant CcPrx4 protein manifested the ability to reduce hydrogen peroxide and protect supercoiled DNA from oxidative damage, suggesting that CcPrx4 protein may play an important role in protecting jellyfish from oxidative damage.

Abstract
In this study, we have reported the immunological properties of cDNA encoding thioredoxin which is obtained from the database of Channa striatus (named as CsTRx) cDNA library. The analysis showed that the CsTRx polypeptide contains a thioredoxin domain between Val(2) and Asn(106). The domain possessed a thioredoxin active family at 24–42 along with a redox active site (also known as catalytic center) at (31)WCGPC(35). The analysis showed that the catalytic center is responsible for the control of protein function. Phylogenetic study showed that CsTRx clustered together with vertebrate TRx-1. Based on the phylogenetic analysis and other bioinformatics analysis, it is confirmed that the characterized CsTRx belongs to TRx-1 family. In addition, the sub-cellular localization prediction analysis showed that CsTRx is a cytosol thioredoxin. The highest gene expression was observed in gill (P < 0.05). Further, its transcriptional modulation was evaluated under fungal (Aphanomyces invadans), bacterial (Aeromonas hydrophila) and H2O2 challenges. The recombinant CsTRx protein was over-expressed and purified using an Escherichia coli expression vector system. We conducted a H2O2 peroxidase assay using recombinant CsTRx protein under various pH and temperature. Further, we studied the influence of recombinant CsTRx protein on C. striatus spleen leukocyte activation. The recombinant CsTRx protein enhanced the cell proliferation in a concentration dependant manner. The results of antioxidant analysis showed that the antioxidant capacity of recombinant CsTRx protein was determined to be 4.2 U/mg protein. We conducted an insulin disulfides assay to study the enzymatic oxidoreductase activity of CsTRx and we observed no activity in the control group. But the recombinant CsTRx protein addition rapidly increased the enzymatic oxidoreductase activity. Over all, the results showed that the CsTRx may contain potential antioxidant properties, which could regulate the oxidative stress created by various biological pathogens as well as chemical stress in the immune system of C. striatus, thus protecting it.

Abstract
Schistosoma japonicum has a complex lifecycle and exhibits dramatic changes in its biology and morphology at different developmental stages. The schistosomulum and adult worm are two stages of this complex lifecycle and differentially expressed proteins in these two stages should be important for survival, development, and reproduction of the parasites. In this study, soluble and hydrophobic proteins were extracted from eggs, cercariae, schistosomula (8d and 19d), and male and female adult worms (42d) of Schistosoma japonicum, and separated by two-dimensional (2D) gel electrophoresis. A total of 1376±52, 928±61, 1465±41, 1230±30, 904±34, and 1080±26 soluble proteins and 1437±44, 845±53, 986±22, 1145±35, 1066±39, and 1123±45 hydrophobic proteins were separated from eggs, cercariae, schistosomula (8d and 19d), and male and female adult worms (42d), respectively. There were 65±14, 27±7, 37±17 and 48±9 soluble protein spots only present in schistosomula (8d and/or 19d) and adult schistosomes (male and/or female). We successfully identified 22 spots from schistosomula and 11 spots from adult schistosomes by mass spectrometry. Quantitative real-time RT-PCR was used to examine six differentially expressed proteins at the transcription level. These proteins only found in schistosomula or adults stage by the proteomics analysis were highly expressed in the corresponding stage at mRNA level. Bioinformatics analysis showed that the differentially expressed proteins from schistosomula were mainly involved in cellular metabolic processes, stress response and developmental process. Differentially expressed proteins from adult schistosomes were involved with gene expression and protein metabolism processes. The results of this study might provide new insights to stimulate further exploration of the mechanism of growth and development in schistosomes and help identify candidate molecules for developing new vaccines or drugs.

Abstract
Di(2-ethylhexyl) phthalate (DEHP) mediates the immune system mainly by triggering the production of reactive oxygen species (ROS) and nitric oxide (NO) in higher animals. In the present study, spatial variation in the expression of immune-related genes in clam (Venerupis philippinarum) under acute short-term DEHP treatment was assessed by qPCR. The expression of six genes including glutamine synthetase (GS), IkB (IK), transcription factor activator protein-1 (AP-1), cyclophilin A-1 (CypA-1), heat shock protein 90 (HSP90) and superoxide dismutase (SOD) was dose-dependent. A negative correlation between expression and DEHP treatment was observed for big defensin (BD), glutathione S-transferase (GST), and thioredoxin peroxidase (TP). Surprisingly, lysozyme (LYZ) exhibited two distinct expression patterns at two DEHP doses. Significant differences between the experimental and control groups were observed for all tested genes at the various time points. Overall, our results revealed that DEHP mediates immune responses in clams by various means, and certain genes are promising candidate for biomarkers in DEHP monitoring.

Abstract
Schistosomiasis is one of the most prevalent and serious parasitic diseases in the world and remains an important public health problem in China. Screening and discovery of an effective vaccine candidate or new drug target is crucial for the control of this disease. In this study, we cloned a cDNA encoding Schistosoma japonicum (S. japonicum) thioredoxin glutathione reductase (SjTGR) from the cDNA of 42-day-old adult worms. The open reading frame (ORF) of the gene was 1791 base pairs (bp) encoding a protein of 596 amino acids. SjTGR was subcloned into pET-32a (+) and expressed in Escherichia coli (E. coli) BL21 (DE3). The recombinant protein rSjTGR exhibited enzymatic activity of 5.13U/mg with DTNB as the substrate, and showed strong immunogenecity. Real-time PCR results indicated that SjTGR was expressed at a higher level in 35-day-old schistosome worms in transcript. We vaccinated BALB/c mice with rSjTGR in combination with MONTANIDE™ ISA 206 VG (ISA 206) and observed a 33.50% to 36.51% (P<0.01) decrease in the adult worm burden and a 33.73%to 43.44% (P<0.01) decrease in the number of eggs counted compared to the ISA 206 or blank control groups in two independent vaccination tests. ELISA analysis demonstrated that rSjTGR induced a high level of SjTGR-specific IgG, IgG1, and IgG 2a antibodies and induced elevated production of IFN-γ. This study provides the basis for further investigations into the biological function of SjTGR and further evaluation of the potential use of this molecule as a vaccine candidate or new drug target is warranted.

Abstract
Microsomal glutathione S-transferase (MGST) functions in cellular defense against xenobiotics and provides protection against the action of lipid hydroperoxides produced as a consequence of oxidative stress. In this study, a full-length cDNA encoding MGST3 (referred to as PmMGST3) was identified from the pearl oyster, Pinctada martensii by a combination of expressed sequence tag (EST) analysis and rapid amplification of cDNA ends (RACE). The full-length cDNA of PmMGST3 is 971 bp and contains a 5' UTR of 39 bp, a 3' UTR of 491 bp with a canonical polyadenylation signal sequence (AATAAA), and an open reading frame (ORF) of 447 bp encoding a polypeptide of 146 residues. The deduced polypeptide contains a conserved motif (FNCx(1)QRx(2)H) characteristic of the MGST3 subfamily. The PmMGST3 transcript could be detected in all tissues tested, with highest transcript level seen in hepatopancreas. Cadmium treatment significantly increased PmMGST3 mRNA levels in gill and hepatopancreas, while bacterial challenge initially depressed mRNA levels and then increased its level in haemocytes, gill and hepatopancreas in a time-dependent manner. In an assay using cumene hydroperoxide as a substrate, we demonstrated that PmMGST3 possesses glutathione-dependent peroxidase activity. These results suggest that PmMGST3 plays an important role in cellular defense against oxidative stress caused by cadmium and bacteria.

Abstract
The expression patterns of different genes encoding antioxidant enzymes and heat shock proteins were investigated, in present study, by real-time quantitative PCR in the hepatopancreas of abalone Haliotis discus hannai fed with different levels of dietary zinc (6.69, 33.8, 710.6 and 3462.5 mg/kg) for 20 weeks. The antioxidant enzymes include Cu/Zn-superoxide dismutase (Cu/Zn-SOD), Mn-superoxide dismutase (Mn-SOD), catalase (CAT), mu-glutathione-s-transferase (mu-GST) and thioredoxin peroxidase (TPx). The results showed that the mRNA expression of these antioxidant enzymes increased and reached the maximum at the dietary zinc level of 33.8 mg/kg, and then dropped progressively. Expression levels of the heat shock proteins (HSP26, HSP70 and HSP90) firstly increased at 33.8 mg/kg dietary Zn level, and reached to the maximum at 710.6 mg/kg, then dropped at 3462.5 mg/kg (p<0.05). Excessive dietary Zn (710.6 and 3462.5 mg/kg) significantly increases the Zn content and significantly decreases the total antioxidant capacity (T-AOC) in hepatopancreas (p<0.05). These findings showed that dietary Zn (33.8 mg/kg) could highly trigger the expression levels of antioxidant enzymes and heat shock proteins, but excessive dietary Zn (710.6 and 3462.5 mg/kg) induces a high oxidative stress in abalone.

Abstract
We have cloned two full-length cDNAs from two ferritin genes (Aifer1 and Aifer2) of the bay scallop, Argopecten irradians (Lamarck 1819). The cDNAs are 1,019 and 827 bp in length and encode proteins of 171 and 173 amino acids, respectively. The 5' UTR of each contains a conserved iron response element (IRE) motif. Sequence analyses reveal that both proteins belong to the H-ferritin family with seven conserved amino acids in the ferroxidase center. Highest expression of Aifer1 is found in the mantle and adductor muscle, while that of Aifer2 is only in the latter tissue. These Aifer genes are differentially expressed following bacterial challenge of the scallop. The expression level of Aifer1 was acutely up-regulated (over 10 fold) at 6 h post-bacteria injection, whereas Aifer2 expression was not significantly changed by bacterial challenge. Both genes were effectively expressed in E. coli BL21 (DE3), producing proteins of similar molecular weight, approximately 23 kDa. Purified Aifer1 and Aifer2 proteins exhibited iron-chelating activity of 33.1% and 30.4%, respectively, at a concentration of 5 mg/ml. Cations, Mg(2+), Zn(2+) and Ca(2+), depressed iron-chelating activity of both proteins. Additionally, the E. coli cells expressing recombinant Aifer1 and Aifer2 showed tolerance to H(2)O(2), providing a direct evidence of the antioxidation function of ferritin. The results presented in this study suggest important roles of Aifer1 and Aifer2 in the regulation of iron homeostasis, immune response, and antioxidative stress in A. irradians.

Abstract
The contamination of marine ecosystems by endocrine disrupting compounds (EDCs) is of great concern. Protein expression profile maybe a good method to help us understand the molecular mechanisms of EDCs-toxicity to aquatic organisms. In this study, the abalone (Haliotis diversicolor supertexta), was selected as the target organism. Toxicological effects of two reference endocrine disruptors: diallyl phthalate (DAP, 50microgL(-1)) and bisphenol-A (BPA, 100microgL(-1)) were investigated after a three months static-renewal exposure on abalones using proteomics to analyze their hepatopancreas tissues. Some enzyme activity parameters of hepatopancreas extracts were also performed, including Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase, peroxidase (POD) and malondialdehyde (MDA) production. After analyzing the proteomics profile of hepatopancreas by 2D gel electrophoresis, we found that 24 spots significantly increased or decreased at protein expression level (2-fold difference) in the 2D-maps from the treatment groups. Eighteen out of 24 protein spots were successfully identified by matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry (MALDI-TOF-MS). These proteins can be roughly categorized into diverse functional classes such as detoxification, oxidative stress, hormone regulating, cellular metabolism and innate immunity. In addition, the enzymatic results indicated that DAP/BPA exposure affected the oxidative stress status and the cellular homeostasis, which partly corroborated the proteomics' results. Taken together, these data demonstrate that proteomics is a powerful tool to provide valuable insights into possible mechanisms of toxicity of EDCs contaminants in aquatic species. Additionally, the results highlight the potential of abalone as a valuable candidate for investigating EDCs impacts on marine ecosystems.

Abstract
Peroxiredoxins (Prxs) play an important role against various oxidative stresses and intra-cellular signal transduction. Peroxiredoxin 6 (PrxVI) was identified from the disk abalone Haliotis discus discus cDNA library and named HdPrxVI. The full length cDNA of HdPrxVI was 1457 bp with a 654 bp open reading frame (ORF) encoding 218 amino acids. The predicted molecular mass and estimated isoelectric point (pI) of HdPrxVI were 24 kDa and 7.3, respectively. The deduced amino acid sequence demonstrated the greatest degree (72.4%) of identity with Crassostrea gigas PrxVI. The conserved peroxidase catalytic center (42PVCTTE47) with a conserved cysteine residue (Cys44) and a catalytic center for PLA2 activity (27GGSWA31) were observed in the sequence, indicating that it is a member of 1-Cys Prx. Real time PCR results revealed that HdPrxVI mRNA is constitutively expressed in all tissues in a tissue-specific manner. During exposure to haemorrhagic septicaemia virus (VHSV), HdPrxVI mRNA transcription was down-regulated in the gill, suggesting that the abalone responded to the viral infection quickly, and HdPrxVI played a physiological role against virus-induced oxidative stress. The purified recombinant HdPrxVI, together with dithiothreitol (DTT), was shown to scavenge H2O2 in human leukemia THP-1 cells and provided protection against H2O2-induced apoptosis.

Abstract
Abalones, belonging to one of the largest marine gastropod mollusks, are economically important seafood in aquaculture worldwide. In recent years, bacterial epidemic infection has been reported in China and other countries, and mass mortality in abalones causes significant economic losses. Immune-related genes and proteins of abalones are seldom reported. However, these functional molecules may play a key role in resisting diseases and maintaining healthy status and are pivotal for studying immunological mechanisms. Here we summarized the advanced research and progresses in abalone immune-related genes and proteins with the purpose of facilitating future study of these target molecules involved in immunological mechanisms.

Abstract
Mycoplasma hyopneumoniae is the causative agent of porcine enzootic pneumonia, which affects pig farms worldwide, causing heavy economic losses. In the infection process, this bacterium is exposed to reactive oxygen species (ROS) from its own metabolism or generated by the host as one of the strategies used to neutralize the pathogen. Although the presence of classical antioxidant enzymes would be expected in M. hyopneumoniae, important genes directly related to protection against ROS, such as superoxide dismutase, catalases and glutathione peroxidase, have not been identified by sequence homology in the genome sequence annotation. Among the few identified M. hyopneumoniae genes coding for proteins possibly involved with suppression of ROS-mediated damage, one (tpx) coding for a peroxiredoxin (MhPrx) has been recognized. The sequence and phylogenetic analyses perfomed in this study indicate that MhPrx is closely related to the atypical 2-Cys peroxiredoxin subfamily, although it has only one cysteine in its sequence. The MhPrx coding DNA sequence was cloned and expressed in Escherichia coli to produce a recombinant MhPrx (rMhPrx), which was purified and used to immunize mice and produce an anti-MhPrx polyclonal antiserum. Probing of M. hyopneumoniae extracts with this antiserum demonstrated that MhPrx is expressed in all three tested strains (J, 7422 and 7448). Cross-linking assays and size-exclusion chromatography indicate that rMhPrx forms dimers, as has been established for atypical 2-Cys peroxiredoxins. Furthermore, a metal-catalysed oxidation system was used to assay the activity of rMhPrx, showing that it can protect DNA from ROS-mediated damage and may play an essential role during infection.
