ARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY 2023; 114:e22030. [PMID: 37282754 DOI: 10.1002/arch.22030] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 05/21/2023] [Accepted: 05/27/2023] [Indexed: 06/08/2023]
Abstract
The antioxidant proteins, peroxiredoxins (Prxs), function to protect insects from reactive oxygen species-induced toxicity. In this study, two Prx genes, CsPrx5, and CsPrx6, were cloned and characterized from the paddy field pest, Chilo suppressalis, containing open reading frames of 570 and 672 bp encoding 189 and 223 amino acid polypeptides, respectively. Then, we investigated the influence of various stresses on their expression levels using quantitative real-time PCR (qRT-PCR). The results showed expression of CsPrx5 and CsPrx6 in all developmental stages, with eggs having the highest level. CsPrx5 and CsPrx6 showed higher expression in the epidermis and fat body, and CsPrx6 also showed higher expression in midgut, fat body, and epidermis. Increasing concentrations of insecticides (chlorantraniliprole and spinetoram) and hydrogen peroxide (H2 O2 ) increased the expression levels of CsPrx5 and CsPrx6. In addition, the expression levels of CsPrx5 and CsPrx6 were almost markedly upregulated in larvae under temperature stress or fed by vetiver. Thus, CsPrx5 and CsPrx6 upregulation might increase the C. suppressalis defense response by reducing the impact of environmental stress, providing a better understanding of the relationship between environmental stresses and insect defense systems.

Abstract
Peroxiredoxin (Prx), an antioxidant enzyme family, has been identified as immune modulating damage-associated molecular patterns (DAMPs) in mammals but not in shrimp. Acute non-lethal heat shock (NLHS) that enhances shrimp Penaeus vannamei resistance to Vibrio parahaemolyticus causing acute hepatopancreatic necrosis disease (VPAHPND). Among the five P. vannamei Prxs (LvPrx) isoforms, LvPrx4, the most abundant in unchallenged shrimp hemocytes that was upregulated in hemocytes following NLHS treatment, is of great interest. The escalation of the LvPrx4 monomer in hemolymph of NLHS treated shrimp indicates that it probably acts as DAMP. This study revealed that pre-challenge with rLvPrx4 could prolong VPAHPND-infected shrimp survival, increase prophenoloxidase (proPO) activity and promote Toll pathway-related genes expression mediated by Toll-like receptor (TLR) 1 and 2. The presented findings elucidated the molecular mechanism of LvPrx4 monomer as DAMP in NLHS-induced VPAHPND resistance by inducing the TLR1/2 signaling pathway and the proPO activating system.

Abstract
Peroxiredoxin (Prx) is an antioxidant protein that widely exists in various organisms. To further investigate the role of Prx in the antioxidant and immune responses of Neocaridina denticulata sinensis, the full-length cDNA sequence of a Prx gene (Nd-Prx) from N. denticulata sinensis was obtained. The open reading frame (ORF) of Nd-Prx is 597 bp and encodes 198 amino acids. Amino acid similarity alignment showed that Nd-Prx contained a conserved sequence region "FYPLDFTFVCPTEI". qRT-PCR assay showed that Nd-Prx was expressed in all tested tissues and its expression was highest in the ovary. Nd-Prx was most highly expressed at 36 h after copper stimulation. Nd-Prx expression levels in hepatopancreas were significantly upregulated after Vibrio parahaemolyticus challenge (P < 0.05). In addition, the recombinant Nd-Prx was prepared and its enzyme activity was most stable at 70 °C with pH of 6.0. The antioxidant activity and DNA protection of recombinant Nd-Prx was also demonstrated. In summary, this study investigated the role of Prx in antioxidant and immune responses of N. denticulata sinensis, which might provide a foundation for further exploring Prx in immune system of crustaceans and for the application in disease control.

Abstract
Peroxiredoxin (Prx) is an antioxidant protein family, which widely exists in organisms and plays an important role in innate immunity. In this study, the full-length cDNA of a Prx gene (NdPrx) was obtained from Neocaridina denticulata sinensis, which contains a 735 bp open reading frame (ORF) and encodes a polypeptide of 244 amino acids. It is inferred that the molecular weight of the encoded amino acid is 27261.20 Da and the theoretical isoelectric point is 6.16. Phylogenetic analysis shows that NdPrx and Prx4 have high homology, so it was named NdPrx4. Multiple alignment analysis showed that the amino acid sequence of NdPrx4 had high homology with Prx4 of other species, and the similarity with Homarus americanus was the highest, 92.86%. Quantitative real-time PCR analysis showed that NdPrx4 was expressed in various tissues of N. denticulata sinensis, and the expression in ovary was the highest. It was speculated that NdPrx4 may be related to maternal immune function. Under the stimulation of Cu2+, the expression of NdPrx4 reached the peak at 36 h, and showed a downward trend until 72 h, indicating that NdPrx4 may play an important role in the stress response of N. denticulata sinensis. Then, NdPrx4 was recombinantly expressed in E. coli, and its enzymatic characteristics of rNdPrx4 were detected. The result showed that the activity of rNdPrx4 was the highest at pH 5.0 and 55 °C. It was found that Mn2+ and Ca2+ can inhibit the activity of rNdPrx4, and Zn2+ increases the activity of rNdPrx4.

FISH & SHELLFISH IMMUNOLOGY 2022; 121:53-61.

Abstract
Virus like particles (VLPs) are non-infectious nanoparticles containing repetitive, high density viral epitopes on the surface and can prevent viral infections in aquatic animals. Here, we evaluated the immuno-stimulation effect of infectious hypodermal and hematopoietic necrosis virus like particle (IHHNV-VLP) using a next generation sequencing in Fenneropenaeus merguiensis to identify the important immune-related genes that may prevent viral infection. The in situ target of IHHNV was predominantly found in gill tissue following IHHNV-VLP administration in juvenile shrimp. Comparative transcriptome analysis in the injected gills showed that there were 326 unigenes expressed differently than the mock-injected samples. One of the most differential genes between the two animal groups was the antioxidative gene, peroxiredoxin (FmPrx), that was up-regulated after 6 h post-VLP injection. Phylogenetic tree analysis showed that this gene could be found among many shrimp species and was closely clustered among Prx families. The expression of FmPrx was also detected in all tissues examined, thus suggesting the multi-functional roles of this gene in many tissues. Administration of IHHNV-VLP in vivo led to a significant increase in peroxidase activity in gill tissue-approximately two-fold versus control animals; the WSSV copy number was significantly reduced. These data suggest that IHHNV-VLP exerts an immune-stimulating effect by enhancing the level of immune-related genes including FmPrx and its corresponding peroxidase activity, which are a well-known part of the shrimp innate immune system.

Abstract
Peroxiredoxin family members could function in host defense against oxidative stress, and modulate immune response. In the present study, a 2-cysteine peroxiredoxin gene named PsPrx1 was isolated from Chinese soft-shelled turtle Pelodiscus sinensis. The PsPrx1 cDNA was composed of 1130 bp, consisted of 199 amino acid residues and included a Redoxin and AphC-TSA domain. As detected by qPCR, PsPrx1 was ubiquitously expressed in the examined tissues with the higher levels in liver and spleen. Upon the immune challenge with A. jandaei bacteria and oxidative stress with ammonia pressure, both mRNA and protein expression level in liver could be significantly enhanced. The results of immunohistochemical examinations showed PsPrx1 was mainly distributed at the junction between the hepatic cells. The general functional properties of PsPrx1 were confirmed using purified rPsPrx1 protein. From the results, rPsPrx1 protein was confirmed to exhibit antioxidant activity and antibacterial properties. The potential for scavenging extracellular H2O2 was evidenced by the purified rPsPrx1 protein in vitro system. In the mixed-function oxidase assay, rPsPrx1 also exhibited a dose-dependent inhibition of DNA damage. These results suggest that rPsPrx1 was implicated defense against microbial pathogens and oxidants, and would provide important information to further understand the functional mechanism of Prx1 in P. sinensis immunity.

Abstract
Acute hepatopancreatic necrosis disease (AHPND), caused by marine bacteria Vibrio Parahaemolyticus, is a huge problem in shrimp farms. The V. parahaemolyticus infecting material is contained in a plasmid which encodes for the lethal toxins PirABVp, whose primary target tissue is the hepatopancreas, causing sloughing of epithelial cells, necrosis, and massive hemocyte infiltration. To get a better understanding of the hepatopancreas response during AHPND, juvenile shrimp Litopenaeus vannamei were infected by immersion with V. parahaemolyticus. We performed transcriptomic mRNA sequencing of infected shrimp hepatopancreas, at 24 hours post-infection, to identify novel differentially expressed genes a total of 174,098 transcripts were examined of which 915 transcripts were found differentially expressed after comparative transcriptomic analysis: 442 up-regulated and 473 down-regulated transcripts. Gene Ontology term enrichment analysis for up-regulated transcripts includes metabolic process, regulation of programmed cell death, carbohydrate metabolic process, and biological adhesion, whereas for down-regulated transcripts include, microtubule-based process, cell activation, and chitin metabolic process. The analysis of protein- protein network between up and down-regulated genes indicates that the first gene interactions are connected to oxidation-processes and sarcomere organization. Additionally, protein-protein networks analysis identified 20-top highly connected hub nodes. Based on their immunological or metabolic function, ten candidate transcripts were selected to measure their mRNA relative expression levels in AHPND infected shrimp hepatopancreas by RT-qPCR. Our results indicate a close connection between the immune and metabolism systems during AHPND infection. Our RNA-Seq and RT-qPCR data provide the possible immunological and physiological scenario as well as the molecular pathways that take place in the shrimp hepatopancreas in response to an infectious disease.

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
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.

Bu R, Yan L, Zhao C, Wang P, Fan S, Wang S, Qiu L. The acute stresses role of the atypical 2-cys peroxiredoxin PmPrx5 in black tiger shrimp (Penaeus monodon) from biological immunity and environmental toxicity stress. FISH & SHELLFISH IMMUNOLOGY 2018; 81:189-203. [PMID: 29578049 DOI: 10.1016/j.fsi.2018.03.042] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2017] [Revised: 03/19/2018] [Accepted: 03/22/2018] [Indexed: 06/08/2023]
Abstract
As a unique atypical 2-Cys Peroxiredoxin (Prx) of the Prx-like superfamily, Peroxiredoxin5 (Prx5) possesses special properties, such as its enzymatic mechanism, wide subcellular distribution and high affinity for peroxides and peroxynitrite. Prx5 plays a crucial role in oxidative stress, immune responses, cell apoptosis, proliferation, differentiation, intracellular signaling, the modulation of gene expression, ecdysis, etc. In this paper, we obtained a full-length Prx5 cDNA sequence (designated PmPrx5) from black tiger shrimp (P. monodon). The full-length PmPrx5 cDNA sequence was 1686 bp containing a 5' untranslated region (UTR) of 76 bp with two nucleotide sequences (AAA), a 3' UTR of 1040 bp with a poly (A) tail and two canonical polyadenylation signal sequences (AATAAA), and an open reading frame of 570 bp encoding 189 amino acid residues with a predicted molecular mass of 20 kDa and a theoretical isoelectric point of 6.29. Phylogenetic trees and multiple sequence alignment showed that the PmPrx5 had strong homology with Prx5 proteins from other species, such as similarity with Palaemon carinicauda (69%) and Macrobrachium rosenbergii (69%), containing the highly conserved functional domain. PmPrx5 mRNA was ubiquitously detected in all tested tissues. After P. monodon was exposed to pathogenic bacteria, osmotic pressure, acidity and alkalinity and the heavy metal, the mRNA expression of PmPrx5 in the gills and hepatopancreas was significantly enhanced (P < 0.01) because of the immune response and declined with heavy metal copper and cadmium challenges as time progressed. The recombinant PmPrx5 protein purified in E. coli (DE3) was further confirmed to exhibit antioxidant activity and antibacterial properties to a certain extent using a bacterial growth inhibition test in both liquid and solid cultures in vitro. E. coli transformed with pRSET-PmPrx5 were dramatically protected in response to metal toxicity stress. Thus, PmPrx5 may be developed as a potential therapeutic drug against pathogenic bacteria and as a biomarker for pollutant levels. This work offers useful clues to further explore the functional mechanism of Prx5 in marine shrimp immunity.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2018; 82:152-164. [PMID: 29374514 DOI: 10.1016/j.dci.2018.01.015] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Revised: 01/22/2018] [Accepted: 01/22/2018] [Indexed: 06/07/2023]
Abstract
Atypical 2-Cys peroxiredoxin (Prx5) is an antioxidant protein that exerts its antioxidant function by detoxifying different reactive oxygen species (ROS). Here, we identified mitochondrial Prx5 from rockfish (SsPrx5) and described its specific structural and functional characteristics. The open reading frame (ORF) of SsPrx5 (570 bp) was translated into a 190-amino acid polypeptide that contained a mitochondrial targeting sequence (MTS), thioredoxin 2 domain, two Prx-specific signature motifs, and three conserved cysteine residues. Sequence comparison indicated that the SsPrx5 protein sequence shared greatest identity with teleost orthologs, where the phylogenetic results showed an evolutionary position within the fish Prx5. The coding sequence of SsPrx5 was scattered in six exons as found in other vertebrates. Additionally, the potent antioxidant functions of recombinantly expressed SsPrx5 protein was demonstrated by insulin reduction and extracellular H2O2 scavenging both in vitro and in vivo. Quantitative real time PCR (qPCR) detected ubiquitous mRNA expression of SsPrx5 in healthy rockfish tissues, with remarkable expression observed in gill, liver, and reproductive tissues. Prompt transcription of SsPrx5 was shown in the immune-stimulated gill and liver tissues against Streptococcus iniae and lipopolysaccharide injection. Taken together, present results suggest the indispensable role of SsPrx5 in the rockfish antioxidant defense system against oxidative stresses and its role in maintaining redox balance upon pathogen invasion.

Identification and characterization of six peroxiredoxin transcripts from mud crab Scylla paramamosain: The first evidence of peroxiredoxin gene family in crustacean and their expression profiles under biotic and abiotic stresses. Mol Immunol 2017; 93:223-235. [PMID: 29220745 DOI: 10.1016/j.molimm.2017.11.029] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Revised: 11/23/2017] [Accepted: 11/28/2017] [Indexed: 01/18/2023]
Abstract
The peroxiredoxins (Prxs) define a novel and evolutionarily conserved superfamily of peroxidases able to protect cells from oxidative damage by catalyzing the reduction of a wide range of cellular peroxides. Prxs have been identified in prokaryotes as well as in eukaryotes, however, the composition and number of Prxs family members vary in different species. In this study, six Prxs were firstly identified from the mud crab Scylla paramamosain by RT-PCR and RACE methods. Six SpPrxs can be subdivided into three classes: (a) three typical 2-Cys enzymes denominated as Prx1/2, 3, 4, (b) two atypical 2-Cys enzymes known as Prx5-1 and Prx5-2, and (c) a 1-Cys isoform named Prx6. The evolutionarily conserved signatures of peroxiredoxin catalytic center were identified in all six SpPrxs. Phylogenetic analysis revealed that SpPrx3, SpPrx4, SpPrx5s and SpPrx6 were clearly classified into Prx3-6 subclasses, respectively. Although SpPrx1/2 could not be grouped into any known Prx subclasses, SpPrx1/2 clustered together with other arthropods Prx1 or unclassified Prx and could be classified into the typical 2-Cys class. The comparative and evolutionary analysis of the Prx gene family in invertebrates and vertebrates were also conducted for the first time. Tissue-specific expression analysis revealed that these six SpPrxs were expressed in different transcription patterns while the highest expression levels were almost all in the hepatopancreas. Quantitative RT-PCR analysis exhibited that the gene expression profiles of six SpPrxs were distinct when crabs suffered biotic and abiotic stresses including the exposures of Vibrio alginolyticus, poly (I:C), cadmium and hypoosmotic salinity, suggesting that the SpPrxs might play different roles in response to various stresses. The recombinant proteins including the SpPrx1/2, SpPrx4, SpPrx5-1 and SpPrx6 were purified and the peroxidase activity assays indicated that all these proteins can reduce H2O2 in a typical DTT-dependent manner. To our knowledge, this is the first study about the comprehensive characterization of Prx gene family in Scylla paramamosain and even in crustaceans. These results would broaden the current knowledge of the whole Prx family as well as be helpful to understand and clarify the evolutionary pattern of Prx family in invertebrate and vertebrate taxa.

Abstract
Peroxiredoxin (Prx) family members play a critical role in host defense against oxidative stress, and are also involved in immune responses following microbial infection. In the present study, we firstly cloned the cDNA of Peroxiredoxin 5 from Procambarus clarkii (denoted as PcPrx5) and investigated its immune functions towards LPS and Poly I:C exposure. The PcPrx5 cDNA was composed of 564 bp and consisting of 187 amino acid residues which included Prx5-like subfamily domain, AHP1 domain and Redoxin domain. The recombinant protein was expressed in Escherichia coli (Transetta DE3), and anti-Prx5 antibodies were prepared. Tissue specific expression analysis showed that PcPrx5 was ubiquitously expressed in all examined tissues. Further, its mRNA transcript was greatest in hepatopancrease, haemocyte followed by gut and stomach, and was weak in muscle. The LPS and Poly I:C exposure could both significantly up-regulate the transcript level of PcPrx5, however the expression trends were different following LPS and Poly I: C treatments. Further, we investigated the antioxidant role of recombinant PcPrx5 protein in vitro by mixed-function oxidase assay; the results demonstrated a dose-dependent inhibition of DNA damage by PcPrx5. Our results implicate PcPrx5 as an important defense against microbial pathogens and oxidants in P. clarkii.

Abstract
Peroxiredoxin 5 (Prx5) belongs to a novel family of evolutionarily conserved antioxidant proteins that protect cells against various oxidative stresses. Generally, no more than one Prx5 transcript had been reported in non-primate species. In this study, two Prx5 genes (coined as SpPrx5-1 and SpPrx5-2) were firstly isolated from the mud crab, Scylla paramamosain, through RT-PCR and RACE methods. The open reading frame of SpPrx5-1 and SpPrx5-2 were 561 bp and 429 bp in length, encoding 186 and 142 amino acids polypeptide, respectively. Both the conserved signatures of peroxiredoxin catalytic center and Prx5-specific domain were identified in SpPrx5-1 and SpPrx5-2. Phylogenetic analysis indicated that both SpPrx5 clustered together with other animal Prx proteins and were classified into Prx5 subfamily. Tissue-specific expression analysis revealed that both SpPrx5-1 and SpPrx5-2 were ubiquitously expressed, highest in hepatopancreas, and showed remarkably similar transcription patterns. Quantitative RT-PCR analysis exhibited that both SpPrx5 genes changed dramatically in hepatopancreas, although showing different expression profiles, after virus-analog poly (I:C) or Vibrio alginolyticus challenge. The expression levels of both SpPrx5s were significantly enhanced in hepatopancreas after poly (I:C) stimulation, while SpPrx5-2 exhibited a more prompt response than SpPrx5-1. Nevertheless, the expression levels of both SpPrx5s were significantly reduced in hepatopancreas after Vibrio alginolyticus challenge in which SpPrx5-1 showed a more prompt response than SpPrx5-2. These results suggested the involvement of SpPrx5s in responses against viral and bacterial infections and further highlighted their functional importance in the immune system of Scylla paramamosain.

Abstract
Peroxiredoxins (Prxs), a diverse family of antioxidant enzymes, exert their antioxidant function through which different peroxide species are detoxified. This study describes both structural and functional characterization of a mitochondrial Prx identified in rock bream, Oplegnathus fasciatus (RbPrx5). The ORF (573 bp) of RbPrx5 encoded a protein of 190 amino acids (20 kDa) containing a putative mitochondrial targeting sequence (residues 1-20) and a thioredoxin-2 motif (residues 31-190) and three conserved Cys residues. Homology assessment and phylogenetic analysis clearly disclosed relatively higher amino acid sequence similarities and a closer evolutionary position of RbPrx5 with those of other teleost homologs. The ORF of RbPrx5 was distributed among six exons as found in other vertebrates, but it possessed an additional exon in its 5'-UTR. In silico examination of RbPrx5 gene's putative promoter region revealed the presence of several cis-elements which may be important in its transcriptional regulation. Constitutive expression of RbPrx5 was detected in eleven tissues with the highest level in the heart. Modulation of RbPrx5 transcription was evidenced from varying mRNA levels in head kidney post in vivo LPS-, poly I:C-, Edwardsiella tarda bacterial- and rock bream iridoviral-challenges. The antioxidant function of RbPrx5 was investigated using recombinant RbPrx5 protein. Results of an in vitro mixed-function oxidase assay demonstrated a dose-dependent inhibition of DNA damage by rRbPrx5. A H2O2 tolerance assay showed that in vivo overexpression of rRbPrx5 increased the bacterial survival under H2O2-mediated oxidative stress condition. These findings provide an overall insight into the structural, expressional and functional aspects of RbPrx5.

Abstract
Peroxiredoxins (Prxs) play important roles in protecting organisms against damage caused by reactive oxygen species (ROS). In this study, we cloned a cDNA of Bombyx mori peroxiredoxin 5 (BmPrx5), which contained a 565-bp open reading frame for a 188-residue protein. Sequence analysis indicated that BmPrx5 belongs to the atypical 2-Cys peroxiredoxin family. Recombinant BmPrx5 purified from Escherichia coli showed antioxidant activity that removes H2 O2 and protects DNA from oxidative damage. Quantitative real-time PCR showed that the level of BmPrx5 mRNA in haemocytes increased early and decreased by 24 h after injection of H2 O2 whereas, in the fat body, the transcript level decreased at 6 h and increased at 12 h. Pseudomonas aeruginosa and Staphylococcus aureus infection resulted in higher levels of H2 O2 in the haemolymph and of BmPrx5 mRNA in haemocytes at 8 h postinfection. These data suggest that BmPrx5 acts as an antioxidant enzyme to protect the silkworm from oxidative damage induced by bacterial infection. Further study is needed to elucidate the exact role of BmPrx5 in the silkworm immune system.

Abstract
Na(+)/K(+)-ATPase (NAK) is one important transporter protein and plays a key role in maintaining osmotic homeostasis in low and high salinity acclimation in variety of crustacean species. The ridgetail white prawn Exopalaemon carinicauda is an euryhaline and economic shrimp species in China, but it remains unclear about its mechanism of salinity adaption. In this study, a full-length of Na(+)/K(+)-ATPase α-subunit (α-NAK) cDNA was cloned from E. carinicauda by using rapid amplification of cDNA ends (RACE) approaches. The full-length cDNA of α-NAK was of 3680 bp, containing an open reading frame (ORF) of 3030 bp encoding a polypeptide of 1009 amino acids with the predicted molecular weight of 112.27 kDa. Eight transmembrane domains and two sites of phosphorylation and ATP binding were identified in E. carinicauda α-NAK. BLAST analysis revealed that the sequence of α-NAK amino acids of E. carinicauda shared more than 75% homologies with those of other crustacean. Real time quantitative RT-PCR analysis indicated that E. carinicauda α-NAK gene could be detected in all the tested tissues with highest expression level in gill. The expression profiles of E. carinicauda α-NAK transcripts were analyzed in gill and hepatopancreas tissues after salinity stresses. The results showed that the expression level of E. carinicauda α-NAK gene in both gill and hepatopancreas reached peak at different time after low and high salinity stresses, and showed different expression profiles. The expression profiles of proPO transcripts in gills after salinity stresses also indicated α-NAK and proPO played synergistic actions for salinity responses in E. carinicauda. These results indicated that E. carinicauda α-NAK involved in stress responses against salinity.

Abstract
The ridgetail white prawn Exopalaemon carinicauda is one of major economic mariculture species in eastern China. The deficiency of genomic and transcriptomic data is becoming the bottleneck of further researches on its good traits. In the present study, 454 pyrosequencing was undertaken to investigate the transcriptome profiles of E. carinicauda. A collection of 1,028,710 sequence reads (459.59 Mb) obtained from cDNA prepared from eyestalk and hemocytes was assembled into 162,056 expressed sequence tags (ESTs). Of these, 29.88 % of 48,428 contigs and 70.12 % of 113,628 singlets possessed high similarities to sequences in the GenBank non-redundant database, with most significant (E value <1e(-10)) unigenes matches occurring with crustacean and insect sequences. KEGG analysis of unigenes identified putative members of biological pathways related to growth and immunity. In addition, we obtained a total of putative 125,112 SNPs and 13,467 microsatellites. These results will contribute to the understanding of the genome makeup and provide useful information for future functional genomic research in E. carinicauda.
