Abstract
Members of the peroxiredoxin family are involved in a wide variety of physiological processes, including the ability to combat the effects of oxidative stress and immune responses, among others. Here, we cloned the cDNA of Procambarus clarkii Peroxiredoxin 1 (designated as PcPrx-1) and investigated its biological role in immune system functions in relation to microbial pathogens. The PcPrx-1 cDNA had 744 base pairs in an open reading frame that encoded 247 amino acid residues and contained a PRX_Typ2cys domain. The analysis of tissue specific expression patterns revealed that PcPrx-1 expression was ubiquitous in all tissues. In addition, the mRNA transcript of PcPrx-1 was found to be highest in the hepatopancreas. There was a significant upregulation of PcPrx-1 gene transcripts after exposure to LPS, PGN, and Poly I:C, but the transcription patterns were different after pathogen challenge. Double-stranded RNA was used to knockdown PcPrx-1, which resulted in a striking change in the expression of all the tested P. clarkii immune-associated genes, including lectin, Toll, cactus, chitinase, phospholipase, and sptzale. On the whole, these results suggest that PcPrx-1 is important to confer innate immunity against pathogens by governing the expression of critical transcripts that encode immune-associated genes.

FISH & SHELLFISH IMMUNOLOGY 2022; 130:409-417. [PMID: 36154891 DOI: 10.1016/j.fsi.2022.09.049] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 09/16/2022] [Accepted: 09/18/2022] [Indexed: 06/16/2023]
Abstract
Vibrio parahaemolyticus causes serious economic losses to the shrimp farming industry. There is still a lack of adequate understanding of the changes in the overall response of N. denticulata sinensis caused by V. parahaemolyticus, particularly with respect to gill tissue, which is severely damaged by the pathogen. In this study, a total of 1358 differentially expressed genes were identified between the PBS control and Vibrio stimulation groups using transcriptome sequencing techniques. After further screening and analysis, many immune-related genes were obtained, involving lysosome pathway, metabolic process, chitin-binding protein, and serine protease family members. In addition, we randomly selected six DEGs in the lysosome pathway for qRT-PCR verification, and the results showed that their expression patterns were consistent with the RNA-seq. The results demonstrate the molecular regulation of the gill tissue response to V. parahaemolyticus infection in N. denticulata sinensis, contributing to the understand of the complex and efficient innate immune system and defense mechanisms in crustaceans.

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
Temperature is an important variable factor in aquaculture which affects the health, survival, behavior, growth, and development of aquatic animals. Palaemon gravieri is one of the main economic shrimps in marine capture fisheries of the East China Sea and the South China Yellow Sea; however, it cannot tolerate high temperatures, thereby, resulting in unsuccessful large-scale farming. Thus far, there are few studies on the effects of acute high temperature on P. graviera. Therefore, it is especially important to study the effects of temperature fluctuations, especially acute high temperature, on P. gravieri. In this study, P. gravieri was treated with acute high-temperature stress, which gradually rose from 15 °C to 30 °C in 3 h, then remained at 30 °C for 12 h. The hepatopancreas of shrimps from five time points was collected once at 15 °C and thereafter, every 3 h after 30 °C. The samples of G0, G1, and G4 were selected for transcriptome analysis. A total of 18,308 unigenes were annotated, of which 7744 were differentially expressed. Most differentially expressed genes (DEGs) come from several physiological and biochemical processes, such as metabolism (GRHPR, ALDH5A1, GDH), immunity (HSP70, Rab5B, Rab10, CASP7), and stress-related process (UGT, GST, HSP60, HSP90). The results indicated that acute high temperature significantly reduced the metabolic capacity of shrimp but enhanced the immune capacity, which seemed to be an emergency metabolic compensation technique to resist stress. This study contributes to ongoing research on the physiological mechanism of P. gravieri response to acute high temperature.

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.

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
White spot syndrome virus (WSSV) is one of the most dangerous pathogen in shrimp aquaculture, which can cause extremely high mortality of shrimp. A full understanding of virus-host interactions is important to prevent viral infection. In the present study, wsv089-interacting molecule Litopenaeus vannamei peroxiredoxins2-like (LvPrx2-L) was selected by the yeast two-hybrid (Y2H) method. The interaction between wsv089 and LvPrx2-L was confirmed by far-western blotting assay. Interestingly, a further study indicated that LvPrx2-L interacted with VP26, and the molecular docking analysis supported the interaction between LvPrx2-L and VP26. Tissues distribution assay showed that LvPrx2-L was detected in all sampled tissues. The highest expression of LvPrx2-L was appeared in hemocytes. Following WSSV challenge, LvPrx2-L mRNA transcripts were significantly increased in the hemocytes and gill. In addition, the relative expression of IE1 and VP28 were remarkably up-regulated in the hepatopancreas and intestines of LvPrx2-L-knockdown shrimp. Moreover, the cumulative survival rate was significantly lower in the LvPrx2-L- silenced group compared with the control and blank groups. Furthermore, LvPrx2-L could regulate the expression of proPO, crustin, ALF3, and CAT at the mRNA level. These findings would further deepen our understanding of WSSV-host interaction and shrimp antiviral response. All these data might useful for assessing the function of LvPrx2-L in the immune response of crustacean.

Abstract
Peroxiredoxins (Prxs) are crucial antioxidant proteins that protect against biotic and abiotic stresses in many organisms, ranging from bacteria to mammals. In the present work, a novel 2-Cys Peroxiredoxin gene (PmPrxn), which contains a 153 bp 5'-terminal untranslated region (5'-UTR), a 636 bp open reading frame encoding a protein with 211 amino acids, and an 898 bp 3'-UTR, was successfully identified and characterized in the black tiger shrimp, Penaeus monodon. Tissue-specific expression analysis revealed that the PmPrxn mRNA was ubiquitously expressed and was comparatively highly expressed in the hepatopancreas. To explore the immunity-related and anti-stress roles of PmPrxn, the gills and hepatopancreas were chosen as target tissues in P. monodon and challenged with Vibrio harveyi, Streptococcus agalactiae, and toxic environmental stressors. The results indicate that PmPrxn might play a vital role in response to biotic and abiotic stresses. Furthermore, the antimicrobial and heavy metal toxicity stress-resistance properties of PmPrxn were evaluated and investigated in vitro using a prokaryotic expression system. These results provide useful information that will help further understand the functional mechanisms of PmPrxn in the defense against bacterial pathogens and environmental acute stresses in shrimp.

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.

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.

Abstract
White spot syndrome virus (WSSV) is one of the most devastating pathogens of cultured shrimp, responsible for massive loss of its commercial products worldwide. The oriental river prawn Macrobrachium nipponense is an economically important species that is widely farmed in China and adult prawns can be infected by WSSV. However, the molecular mechanisms of the host pathogen interaction remain unknown. There is an urgent need to learn the host pathogen interaction between M. nipponense and WSSV which will be able to offer a solution in controlling the spread of WSSV. Next Generation Sequencing (NGS) was used in this study to determin the transcriptome differences by the comparison of control and WSSV-challenged moribund samples, control and WSSV-challenged survived samples of hepatopancreas in M. nipponense. A total of 64,049 predicted unigenes were obtained and classified into 63 functional groups. Approximately, 4,311 differential expression genes were identified with 3,308 genes were up-regulated when comparing the survived samples with the control. In the comparison of moribund samples with control, 1,960 differential expression genes were identified with 764 genes were up-regulated. In the contrast of two comparison libraries, 300 mutual DEGs with 95 up-regulated genes and 205 down-regulated genes. All the DEGs were performed GO and KEGG analysis, overall a total of 85 immune-related genes were obtained and these gene were groups into 13 functions and 4 KEGG pathways, such as protease inhibitors, heat shock proteins, oxidative stress, pathogen recognition immune receptors, PI3K/AKT/mTOR pathway, MAPK signaling pathway and Ubiquitin Proteasome Pathway. Ten genes that valuable in immune responses against WSSV were selected from those DEGs to furture discuss the response of host to WSSV. Results from this study contribute to a better understanding of the immune response of M. nipponense to WSSV, provide information for identifying novel genes in the absence of genome of M. nipponense. Furthermore, large number of transcripts obtained from this study could provide a strong basis for future genomic research on M. nipponense.

Abstract
As a new-found aquaculture pathogen, Spiroplasma eriocheiris, has resulted in inconceivable economic losses in aquaculture. In the infection of S. eriocheiris, the Procambarus clakii hemocytes have indicated to be major target cells. What was designed to examine in our study is the hemocytes' immune response at the protein levels. Before the pathogen was injected and after 192 h of post-injection, the differential proteomes of the crayfish hemocytes were analyzed immediately by isobaric tags for relative and absolute quantization (iTRAQ) labeling, followed by liquid chromatogramphytandem mass spectrometry (LC-MS/MS). This research had identified a total of 285 differentially expressed proteins. Eighty-three and 202 proteins were up-regulated and down-regulated, respectively, caused by the S. eriocheiris infection. Up-regulated proteins included alpha-2-macroglobulin (α2M), vitellogenin, ferritin, etc. Down-regulated proteins, involved with serine protease, peroxiredoxin 6, 14-3-3-like protein, C-type lectin, cdc42 homolog precursor, etc. The prophenoloxidase-activating system, antimicrobial action involved in the immune responses of P. clarkii is considered to be damaged due to S. eriocheiris infection. The present work could lay the foundation for future research on the proteins related to the susceptibility/resistance of P. clarkii to S. eriocheiris. In addition, it is helpful for our understanding molecular mechanism of disease processes in crayfishes.

Abstract
Peroxiredoxin (Prx) family members play a key role in host defense against oxidative stress, and modulate immune responses following microbial infection. Here, we cloned and characterized Procambarus clarkii Prx4 (Peroxiredoxin 4) cDNA, a regulator of oxidative stress and its expression analysis upon lipopolysaccharide (LPS) and polyriboinosinic polyribocytidylic acid (Poly I:C) infection. The cDNA fragment of PcPrx4 was 744 bp in length, encoding a putative protein of 248 amino acid residues. Real-time quantitative reverse transcription-PCR (qRT-PCR) analysis showed that the PcPrx4 was expressed in all the examined tissues, and it was highest in the hepatopancreas followed by the hemocytes and gill. The challenge with LPS and Poly I:C significantly up-regulated the expression of PcPrx4 in hepatopancreas, hemocytes and gill when compared with the control. Recombinant PcPrx4 protein was used to investigate the antioxidant function in vitro by mixed-function oxidase assay. The results demonstrated a dose-dependent inhibition of DNA damage by rPcPrx4 protein. Altogether, our results imply that PcPrx4 is implicated in defense against microbial pathogens and oxidants in P. clarkii.

Abstract
Low temperature and air exposure were the key attributes for waterless transportation of fish and shrimp. In order to investigate the oxidative stress and antioxidant responses of the live shrimp Litopenaeus vannamei in the mimic waterless transportation, live shrimp were cooled at 13 °C for 3 min, stored in oxygen at 15 °C for 12 h, and then revived in water at 25 °C. The survival rate of shrimp under this waterless transportation system was over 86.67%. The ultrastructure of hepatopancreas cells were observed while activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), glutathione peroxidase (GSH-Px), antisuperoxide anion free radicals (ASAFR), total antioxidant capacity (TAOC), reactive oxygen species (ROS) production, content of malondialdehyde (MDA) and relative mRNA expressions of CAT and GSH-Px in the hemolymph and hepatopancreas were determined. Slight distortions of some organelles in hepatopancreas cells was reversible upon the shrimp revived from the cold shock. The activities of SOD, POD, CAT, GSH-Px, TAOC, ROS production and relative mRNA expressions of CAT and GSH-Px increased following the cold shock and reached peak levels after 3 or 6 h of storage, and then decreased gradually. There was no significant difference between the fresh and the revived shrimp in SOD, POD, GSH-Px, TAOC, ROS, MDA and relative mRNA expressions of CAT and GSH-Px. The oxidative stress and antioxidant responses were tissue-specific because hepatopancreas seemed to have a greater ability to defend against organelle damage and was more sensitive to stress than hemolymph based on the results of SOD activity, MDA content and GSH-Px mRNA expression. These results revealed that low temperature and air exposure caused significant oxidative and antioxidant responses, but did not lead to irreversible damages in this waterless system.

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
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
The white shrimp Litopenaeus vannamei has been greatly impacted by Vibrio infection. In this study, we investigated the intestinal barrier response of L vannamei following challenge with Vibrio parahaemolyticus E1, by examining morphological changes and transcriptome expression levels. A total of 16,4420 unigenes were obtained from RNAseq data after quality control and assembly, and 4646 differentially expressed genes (DEGs) were identified following Vibrio challenge, of which 2469 unigenes were significantly up-regulated and 2177 were significantly down-regulated. DEGs were determined to be involved in various physical, chemical and immunological intestinal barrier functions, including peritrophin, cytoskeleton and cell junction, pattern recognition receptors, antimicrobial peptide and immune signaling pathways, serine protease/protease inhibitor and prophenoloxidase system, apoptosis and phagocytosis, and antioxidant systems. Fifteen DEGs were randomly selected for validation by real-time quantitative PCR (RT-qPCR) and showed results consistent with the RNA-seq data. Intestinal epithelial cell morphology was also affected by Vibrio challenge, showing epithelial detachment, nuclear pyknosis, and destruction of cell junctions. These results improve our current understanding of the intestinal barrier function in the shrimp response to bacterial infection.

FISH & SHELLFISH IMMUNOLOGY 2017; 69:119-127.

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) 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
1-cysteine peroxiredoxin (Prx6) is an antioxidant enzyme that protects cells by detoxifying multiple peroxide species. This study aimed to describe molecular features, functional assessments and potential immune responses of Prx6 identified from the big-belly seahorse, Hippocampus abdominalis (HaPrx6). The complete ORF (666 bp) of HaPrx6 encodes a polypeptide (24 kDa) of 222 amino acids, and harbors a prominent peroxiredoxin super-family domain, a peroxidatic catalytic center, and a peroxidatic cysteine. The deduced amino acid sequence of HaPrx6 shares a relatively high amino acid sequence similarity and close evolutionary relationship with Oplegnathus fasciatus Prx6. The purified recombinant HaPrx6 protein (rHaPrx6) was shown to protect plasmid DNA in the Metal Catalyzed Oxidation (MCO) assay and, together with 1,4-Dithiothreitol (DTT), protected human leukemia THP-1 cells from extracellular H2O2-mediated cell death. In addition, quantitative real-time PCR revealed that HaPrx6 mRNA was constitutively expressed in 14 different tissues, with the highest expression observed in liver tissue. Inductive transcriptional responses were observed in liver and kidney tissues of fish after treating them with bacterial stimuli, including LPS, Edwardsiella tarda, and Streptococcus iniae. These results suggest that HaPrx6 may play an important role in the immune response of the big-belly seahorse against microbial infection. Collectively, these findings provide structural and functional insights into HaPrx6.

Abstract
Thioredoxin peroxidases (Tpxs) play a crucial role in protection against oxidative damage in several insect species. However, studies on the characteristics and functions of Tpxs in Helicoverpa armigera are lacking. In this study, a novel 2-Cys Tpx gene from H. armigera (HaTpx) was identified. Sequence analysis revealed that HaTpx is highly conserved and shares two catalysis regions (VCP) with other insect species. HaTpx mRNA was found to be expressed in an age-dependent manner and was ubiquitous in all tissues examined. Hormone treatment showed that the expression of HaTpx is clearly induced by 20-hydroxyecdysone but repressed by Juvenile hormone. Additionally, extreme temperature, ultraviolet light, mechanical injury, Escherichia coli, Metarhizium anisopliae, nucleopolyhedrovirus (NPV) infection, and H2O2 treatment markedly induced HaTpx gene expression. Reactive oxygen species (ROS) levels in hemocytes and MDA concentrations in the hemolymph after NPV infection were evaluated, and the results indicated that NPV infection causes excessive ROS generation. After knockdown of HaTpx by RNA interference, the expression of three antioxidant genes (Cu/ZnSOD, Trx, and TrxR) was increased, whereas two antioxidant genes (CAT and GPX) showed decreased expression. Moreover, the susceptibility of H. armigera to NPV infection increased after HaTpx knockdown. These results indicated that HaTpx contributes to the susceptibility of H. armigera to NPV, and the results also provide a theoretical basis for a novel strategy for developing new chemicals and microbial pesticides that target HaTpx gene for controlling H. armigera.

Abstract
Thioredoxin (TRX) is one of the key systems responsible for keeping the intracellular environment in a highly reduced state. In this study, a full-length TRX cDNA sequence (ToTRX) from golden pompano Trachinotus ovatus was identified after pyrosequencing of golden pompano cDNA library. ToTRX cDNA is comprised of 786 bp, and contained a 324 bp open reading frame (ORF) encoding a 107 amino acid polypeptide, a 5' untranslated region (UTR) of 116 bp, and a long 3'- UTR of 346 bp. Multiple sequence alignment revealed that ToTRX contained the highly conserved redox active disulphide/dithiol site (CGPC) of the thioredoxin active family, and phylogenetic tree showed that ToTRX had a closer evolution relationship with TRX from Oplegnathus fasciatus and Anoplopoma fimbria. ToTRX mRNA is ubiquitously expressed in all detected tissues with the higher expression levels in the stomach, gill and fin tissues. The expression of ToTRX mRNA was significantly up-regulated in liver, kidney, intestine and spleen of golden pompano injected with Photobacterium damselae. The recombinant ToTRX protein (rToTRX) was expressed in Escherichia coli BL21 (DE3), and then purified and refolded. The insulin disulfides assay was performed to investigate the enzymatic oxidoreductase activity of rToTRX, and the results demonstrated that rToTRX exhibited a high reducing activity in presence of DTT, while no activity was observed in the regroup without DTT and blank control group. Over all, the study provided the useful information to help further understand the functional mechanism of TRX in marine fish immunity.

Abstract
Peroxiredoxin 1 (Prx 1) is an important antioxidant protein that can protect organisms against the toxicity of reactive oxygen species. In this study, a full-length Prx 1 cDNA sequence (ToPrx 1) was identified from golden pompano (Trachinotus ovatus). The ToPrx 1 cDNA was 1049 base pairs (bp) long and contained a 5'-untranslated region (UTR) of 127 nucleotides, a 3'-UTR of 328 nucleotides, and a 594 bp open reading frame (ORF) encoding a 197 amino acid polypeptide. The ToPrx 1 protein showed strong homology (79-91%) with Prx 1 proteins from other species and contained the conserved Prx domain and the signature of the peroxidase catalytic center. Phylogenetic analysis revealed that ToPrx 1 was in the fish Prx 1 subgroup, which suggests that ToPrx 1 could belong to the 2-Cys Prx subgroup. ToPrx 1 mRNA was ubiquitously detected in all tested tissues, and its expression was comparatively high in the fin, spleen, kidney, intestine, eye, gill, and blood. The expression levels of ToPrx 1 mRNA were significantly up-regulated in liver, spleen, kidney, and intestine of golden pompano injected with Photobacterium damselae. The recombinant ToPrx 1 protein (rToPrx 1) was expressed and purified through affinity chromatography and refolded successfully using ion-exchange chromatography. The antioxidant activity assay of rToPrx 1 showed that it could reduce insulin in the presence of dithiothreitol, which suggests that the antioxidant function of rToPrx 1 is thiol dependent. This study provides useful information to help further understand the functional mechanism of Prx 1 in marine fish immunity.

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.

[PMID: 25542382 DOI: 10.1016/j.fsi.2014.12.011] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2014] [Revised: 12/02/2014] [Accepted: 12/15/2014] [Indexed: 06/04/2023]
Abstract
Pathogenic infections and environmental factors cause a variety of stresses in fish including oxidative stress by rapid elevation of reactive oxygen species (ROS) and reactive nitrogen species (RNS). Transcriptional activation and expression of antioxidant enzymes are essential for reducing the oxidative stress. In this study, we present the molecular characterization, immune responses and ROS scavenging activity of mitochondrial peroxiredoxin 3 from Oplegnathus fasciatus (RbPrx3). Coding sequence (CDS) of RbPrx3 contains 248 amino acids polypeptide which consists of highly conserved peroxiredoxin super family domain and two cysteine residues. Pairwise sequence comparison revealed that RbPrx3 has the greatest identity (94.8%) to Sparus aurata Prx3. Transcriptional analysis of RbPrx3 indicated the ubiquitously expressed mRNA in wide array of organs showing the highest expression in the liver of rock bream. Upon immune challenge of Edwardsiella tarda, Streptococcus iniae, rock bream iridovirus (RBIV) and lipopolysaccharide (LPS), RbPrx3 mRNA level was up-regulated in immunocompetent liver tissues compared to unchallenged fish. Purified recombinant RbPrx3 treated THP-1 cells showed higher survival rate against H(2)O(2) induced oxidative stress and significantly reduced the level of intracellular ROS. Overall results from our study suggest that RbPrx3 may be involved in broader functions such as regulating oxidative stresses by scavenging ROS and activating immune responses in rock bream.

Abstract
Thioredoxin peroxidases (Tpxs) are a ubiquitous family of antioxidant enzymes that play important roles in protecting organisms against oxidative stress. Here, one Tpx was cloned from Spodoptera litura named as SlTpx. The full-length cDNA consists of 1165 bp with 588 bp open reading frame, encoding 195 amino acids. The putative amino acid sequence shared >70% identity with Tpxs from other insects. Phylogenetic analysis revealed that SlTpx is closely related to other available lepidopteran Tpxs. Real-time PCR analysis showed that SlTpx can be induced by Nomuraea rileyi infection in some detected tissues at the mRNA level. The strongest expression was found in hemocytes of unchallenged and N. rileyi-challenged S. litura. Western blotting showed SlTpx protein in the hemocytes, head and cuticle from normal S. litura. However, when N. rileyi was inoculated into the body cavity of S. litura larvae, SlTpx protein was detected in head, hemocytes, fatbody, midgut, malpighian tubule, but not in the hemolymph and cuticle. Moreover, time-course analysis showed that SlTpx mRNA/protein expression levels were up-regulated in the hemocytes, when S. litura were infected by N. rileyi or injected with H2O2. The levels of N. rileyi-induced reactive oxygen species (ROS) in hemocytes were evaluated, and revealed that N. rileyi infection caused generation of ROS, and induced changes in expression of SlTpx. In addition, the heterologously expressed protein of this gene in Escherichia coli showed antioxidant activity; it removed H2O2 and protected DNA. Knocking down SlTpx transcripts by dsRNA interference resulted in accelerated insect death with N. rileyi infection. This is believed to be the first report showing that SlTpx has a significant role in resisting oxidative stress caused by N. rileyi infection.

Abstract
Peroxiredoxins (Prx) are a family of antioxidant proteins and perform important functions in intracellular signal transduction. Here, we report a Prx gene from Chinese shrimp Fenneropenaeus chinensis. The full-length cDNA of FcPrx gene contained an open reading frame of 735 bp encoding a polypeptide of 275 amino acids. The molecular mass of the deduced amino acid of FcPrx is 27445.43 Da with an estimated pI of 5.71. Sequence comparison showed that the FcPrx shares high identities with Prx IVs and it was named FcPrx4. A real-Time PCR (qRT-PCR) assay was developed to assess the mRNA expression of FcPrx4 in different tissues and temporal expression in hemocytes and hepatopancreas of F. chinensis challenged by white spot syndrome virus (WSSV). Transcripts of FcPrx4 can be detected in all tissues examined. The expression of FcPrx4 showed significant up-regulation in shrimp hemocytes and hepatopancreas after artificial infection with WSSV. A fusion protein containing FcPrx4 was produced in vitro and was confirmed by Matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) assay. And activity analysis indicated that the recombinant FcPrx4 proteins can reduce H2O2 in the presence of dithiothreitol.

Abstract
Peroxiredoxin is a superfamily of antioxidative proteins that play important roles in protecting organisms against the toxicity of reactive oxygen species. In this study, a full-length of peroxiredoxin 5 (designated EcPrx5) cDNA was cloned from the ridgetail white prawn Exopalaemon carinicauda by using rapid amplification of cDNA ends (RACE) approaches. The full-length cDNA of the EcPrx5 was of 827 bp, containing a 5′ untranslated region (UTR) of 14 bp, a 3′ UTR of 228 bp with a poly (A) tail, and an open reading frame of 585 bp encoding a polypeptide of 194 amino acids with the predicted molecular weight of 20.83 kDa and estimated isoelectric point of 7.62. BLAST analysis revealed that amino acids of EcPrx5 shared 89, 68, 66, 65, 53 and 51 % identity with that of Macrobrachium rosenbergii, Megachile rotundata, Harpegnathos saltator, Acromyrmex echinatior, Danio rerio, and Homo sapiens counterparts, respectively. The conserved Prx domain and the signature of peroxiredoxin catalytic center identified in EcPrx5 suggested that EcPrx5 belonged to the atypical 2-Cys Prx subgroup. Real time quantitative RT-PCR analysis indicated that EcPrx5 could be detected in all the tested tissues with highest expression level in hepatopancreas. As time progressed, the expression level of EcPrx5 both in hemocytes and hepatopancreas increased in the first 6 h after Vibrio anguillarum and white spot syndrome virus challenge, and showed different expression profiles. The results indicated that EcPrx5 involved in immune response against bacterial and viral infection in E. carinicauda.

Expression profiles of selenium dependent glutathione peroxidase and glutathione S-transferase from Exopalaemon carinicauda in response to Vibrio anguillarum and WSSV challenge. FISH & SHELLFISH IMMUNOLOGY 2013; 35:661-670.

Abstract
A selenium-dependent glutathione peroxidase cDNA was obtained from the ridgetail white prawn Exopalaemon carinicauda (EcGPx) by rapid amplification of cDNA ends (RACE) methods. The full-length cDNA of EcGPx was 946 bp, which contains a 5'-untranslated region (UTR) of 105 bp, 3'-UTR of 280 bp with a poly (A) tail, an open reading frame (ORF) of 561 bp, encoding a 186 amino-acid polypeptide with the predicted molecular weight of 21.35 kDa and estimated isoelectric point of 7.65. It involves a putative selenocysteine (U39) residue which is encoded by an opal codon, (220)TGA(222), and forms an active site with residues Q73 and W141. Sequence analysis revealed that a GPx signature motif 2 ((63)LAFPCNQF(70)), an extra active site motif ((151)WNFEKF(156)), two putative N-glycosylation site ((75)NNT(77) and (107)NGS(109)), and two arginine residues (R89 and R167) were observed in the EcGPx sequence. Comparison of amino acid sequences showed that white shrimp GPx is more closely related to GPx1 and GPx2 subgroups. Quantitative real-time RT-PCR analysis indicated that two glutathione antioxidant enzymes of E. carinicauda, glutathione peroxidase (designated EcGPx) and glutathione S-transferase (designated EcGST) were widely expressed in all the tested tissues, but showed different expression patterns. After Vibrio anguillarum and WSSV challenge, EcGPx and EcGST transcripts both in hemocytes and hepatopancreas increased in the first 6 h and 3 h, respectively. The results suggested that EcGPx and EcGST might be associated with the immune defenses to V. anguillarum and WSSV in E. carinicauda.

Abstract
Recent evidences suggest that invertebrates express families of immune molecules with high levels of sequence diversity. Hemocyanin is an important non-specific immune molecule present in the hemolymph of both mollusks and arthropods. In the present study, we characterized a novel alternative splicing variant of hemocyanin (cHE1) from Litopenaeus vannamei that produced mRNA transcript of 2579 bp in length. The isoform contained two additional sequences of 296 and 267 bp in the 5'- and 3'-terminus respectively, in comparison to that of wild type hemocyanin (cHE). Sequence of cHE1 shows 100% identity to that of hemocyanin genomic DNA (HE, which does not form an open reading frame), suggesting that cHE1 might be an alternative splicing variant due to intron retention. Moreover, cHE1 could be detected by RT-PCR from five tissues (heart, gill, stomach, intestine and brain), and from shrimps at stages from nauplius to mysis larva. Further, cHE1 mRNA transcripts were significantly increased in hearts after 12h of infection with Vibrio parahemolyticus or poly I: C, while no significant difference in the transcript levels of hepatopancreas cHE was detected in the pathogen-treated shrimps during the period. In summary, these studies suggested a novel splicing variant of hemocyanin in shrimp, which might be involved in shrimp resistance to pathogenic infection.

Abstract
Peroxiredoxin2 (Prx2) protein is an important member in cellular antioxidant protein superfamily. Prx2 exists widely in prokaryotes and eukaryotes, it not only plays a part in eliminate reactive oxygen, but also takes effect in many other metabolic activities, such as stimulate epithelial cell proliferation, participate in the signal transduction in cells and so on. After molecular cloning we got that the complete cDNA sequence of Prx2 consists 882 bp, including a 5'-UTR of 46 bp, an open reading frame (ORF) of 591 bp, and a 3'-UTR of 245 bp. The complete gene of miiuy croaker Prx2 has 5 exons and 4 introns. The deduced 197 amino acid residues of miiuy croaker Prx2 consists a Val-Cys-Pro (VCP) motifs. In order to better elucidate the immune mechanisms of the Prx2 in the lower vertebrates, we conducted a research about the Prx2 gene of miiuy croaker and its expression pattern after bacterial infection. Real-time PCR (RT-PCR) results showed that expression of Prx2 was up-regulated in kidney, liver and spleen under infection with Vibrio anguillarum, and expressed level differently in ten different uninjected tissues. Our results suggested that Prx2 might be involved in immune defence in miiuy croaker.

Abstract
The annual production of shrimp culture in mainland of China has been over one million tons for several years. The major cultivated penaeidae species are Litopenaeus vannamei, Fenneropenaeus chinensis, Penaeus monodon and Marsupenaeus japonicus. Due to the importance of shrimp aquaculture in China, researchers have paid more attention to the molecular mechanism of shrimp disease occurrence and tried to develop an efficient control strategy for disease. This paper summarizes the research progress related to innate immunity of penaeid shrimp made in the last decade in Mainland China. Several pattern recognition receptors, such as lectin, toll, lipopolysaccharide and β-1,3-glucan binding protein (LGBP) and tetraspanin were identified. The major signal transduction pathways, including Toll pathway, IMD pathway, which might be involved in the immune response of shrimp, were focused on and most of the components in Toll pathway were identified. Also, cellular immune responses such as phagocytosis and apoptosis were regarded playing very important roles in anti-WSSV infection to shrimp. The molecules involved in the maintenance of the immune homeostasis of shrimp and the progress on molecular structure and pathogenic mechanism of WSSV were summarized. Therefore, the brief outline about the immune system of shrimp is drawn based on the recent data which will help us to understand the immune responses of shrimp to different pathogens.

Abstract
Antioxidant enzymes, such as glutathione peroxidase (GPx), catalase (CAT), and peroxiredoxin (Prx), are essential components in cells to eliminate excessive reactive oxygen species such as hydrogen peroxide (H(2)O(2)). GPx, CAT, and Prx genes have been reported in penaeid shrimp, and they showed different expression profiles at transcription or protein level when shrimps were challenged by microbes. In order to learn the relationship among the above three genes in their function, GPx, CAT, and Prx transcripts were analyzed, and the variation of GPx and CAT enzyme activity was detected when shrimp was injected with H(2)O(2) or one antioxidant enzyme gene was silenced in shrimp by double-strand RNA injection. The results indicated that there existed some relationships among three antioxidant enzyme genes, CAT, GPx, and Prx in shrimp at transcriptional level. The transcription of CAT and GPx could be directly induced by H(2)O(2) injection, while the transcription of Prx cannot be induced by H(2)O(2). Decreased transcription level of CAT or GPx could lead to increased transcription of the other two genes, which suggested that there existed some compensation among these three antioxidant enzyme genes. These data can help us to understand the roles of antioxidant enzymes in crustacean.

Abstract
In this study, we describe the molecular characterization, immune responses of rock bream, Oplegnathus fasciatus peroxiredoxin 6 cDNA (RbPrx6) and DNA protection activity of its recombinant protein. The full-length cDNA sequence of RbPrx6 was identified after pyrosequencing of rock bream cDNA library. RbPrx6 consists of 663 bp open reading frame (ORF) that codes for a putative protein of 221 amino acids with predicted molecular mass of 27 kDa. It showed characteristic peroxiredoxin super-family domain similar to vertebrate Prx counterparts. In the pair-wise comparison, RbPrx6 showed the highest amino acid identity (92.8%) to Scophthalmus maximus Prx6. Real-time RT-PCR analysis revealed that constitutive expression of RbPrx6 transcripts in eleven tissues selected from un-challenged fish showing the highest level in liver. Synthetic polyinosinic:polycytidylic acid (poly I:C) and iridovirus containing supernatant, up-regulated the RbPrx6 mRNA in liver. Purified recombinant RbPrx6 protein was able to protect supercoiled plasmid DNA from damages that is induced by metal-catalyzed generation of reactive oxygen species. Our results suggest that RbPrx6 may play an important role in regulating oxidative stress by scavenging of ROS, involving immune reactions and minimizing the DNA damage in rock bream.

Abstract
In this study, we have reported a full length of peroxiredoxin (designated MrPrdx) gene, identified from the transcriptome of freshwater prawn Macrobrachium rosenbergii. The complete gene sequence of the MrPrdx is 940 base pairs in length, and encodes 186 amino acids. MrPrdx contains a long thioredoxin domain in the amino acid sequence between 34 and 186. The gene expressions of MrPrdx in healthy and the infectious hypodermal and hematopoietic necrosis virus (IHHNV) challenged M. rosenbergii were examined using quantitative real time polymerase chain reaction. MrPrdx is highly expressed in all the other tissues of M. rosenbergii considered for analysis and the highest in gills. The expression is strongly up-regulated in gills after IHHNV infection. To understand MrPrdx functional properties, the recombinant MrPrdx protein was expressed in Escherichia coli BL21 (DE3) and purified. A peroxidise activity assay was conducted using recombinant MrPrdx protein at different concentrations. This peroxidises activity showed that the recombinant MrPrdx is a thiol-dependant protein. Additionally, this result showed that recombinant MrPrdx protein, as a secretory protein can remove H₂O₂ and protect DNA damage. This finding leads a possible way to propose the recombinant MrPrdx protein as an effective medicine for reactive oxygen species (ROS) related diseases.

Abstract
Peroxiredoxin (Prx) is an antioxidant protein, which protects organisms against various oxidative stresses. In this study, we isolated Peroxiredoxin cDNA from the muscle tissues of American white shrimp, Litopenaeus vannamei, using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE). The full-length cDNA consists of 962-bp, which includes a 49-bp 5′-untranslated region (UTR), a 316-bp 3′-untranslated region, and a 597-bp open reading frame (ORF) encoding 198 amino acids. The signal peptide sequence was not found in this cDNA. We aligned the deduced amino acid sequence with the known amino acid sequences of Fenneropenaeus indicus, Fenneropenaeus chinensis, Marsupenaeus japonicus, Scylla serrata, Drosophila melanogaster, Bos taurus, Branchiostoma belcheri, Anoplopoma fimbria, and Rattus norvegicus, and the sequence similarities scores were found to be 97%, 96%, 95%, 83%, 72%, 70%, 80%, 81%, and 75%, respectively. We also found 2-cysteine (Cys) residues in this peroxiredoxin sequence. The RT-PCR analysis revealed that the peroxiredoxin mRNA was expressed in the gills, hepatopancreas, muscles, intestine, and hemocytes. Studies using this newly cloned peroxiredoxin gene from Litopenaeus vannamei will add to the existing knowledge base on the physiological role of peroxiredoxin in shrimp species.

FISH & SHELLFISH IMMUNOLOGY 2011; 31:294-302.

Abstract
The aim of this work was to underline the physiological role of the antioxidant peroxiredoxin (PRDX) family in gilthead sea bream (Sparus aurata L.), a perciform fish extensively cultured in the Mediterranean area. First, extensive BLAST searches were done on the gilthead sea bream cDNA database of the AQUAMAX European Project (www.sigenae.org/iats), and six contigs were unequivocally identified as PRDX1-6 after sequence completion by RT-PCR. The phylogenetic analysis evidenced three major clades corresponding to PRDX1-4 (true 2-Cyst PRDX subclass), PRDX5 (atypical 2-Cys PRDX subclass) and PRDX6 (1-Cys PRDX subclass) that reflected the present hierarchy of vertebrates. However, the PRDX2 branch of modern fish including gilthead sea bream was related to the monophyletic PRDX1 node rather than to PRDX2 cluster of mammals and primitive fish, which probably denotes the acquisition of novel functions through vertebrate evolution. Transcriptional studies by means of quantitative real-time PCR evidenced a ubiquitous PRDX gene expression that was tissue specific for each PRDX isoform. In a second set of transcriptional studies, liver and head kidney were chosen as target tissues in fish challenged with i) the intestinal parasite Enteromyxum leei, ii) a plant oil (VO) diet with deficiencies in essential fatty acids and iii) prolonged exposure to high-rearing densities. These studies showed that PRDX genes were highly and mostly constitutively expressed in the liver and were not affected by dietary intervention or high density. In contrast, head kidney was highly sensitive to the different experimental challenges: significantly lower values were found for PRDX5 in the three trials, for PRDX6 in parasitized and high density fish and for PRDX1 in parasitized and VO fish. PRDX2, 3 and 5 were decreased only in VO, high density and parasitized animals, respectively. These findings would highlight the role of PRDXs as integrative and highly predictive biomarkers of health and welfare in fish and gilthead sea bream in particular.

Abstract
Thioredoxin (TRX) is involved in cell redox homeostasis. In addition, it is responsible for maintaining proteins in their reduced state. In our study, a Fenneropenaeus chinensis thioredoxin (FcTRX) gene was identified from the Chinese white shrimp. The full length of FcTRX was 777 bp, including a 60 bp 5' untranslated region (UTR), a 318 bp open reading frame (ORF) encoding a 105 amino acids protein, and a 399 bp 3' UTR. FcTRX contained a TRX domain with a conserved motif of Cys-Gly-Pro-Cys (CGPC). No signal peptide was predicted by SMART analysis. The molecular mass and pI of FcTRX were 12 kDa and 4.62, respectively. FcTRX is a widely distributed gene, and its mRNA is detected in hemocytes, hearts, hepatopancreas, gills, stomach, and intestine from an unchallenged shrimp. The expression level of FcTRX was the highest in hepatopancreas, where it was down-regulated to the lowest level at 12 h white spot syndrome virus (WSSV) challenge. In the gills, it went up to the highest level at 6 h. Western blot showed that FcTRX protein in hepatopancreas challenged with WSSV was down-regulated from 2 h to 12 h and then restored to the level similar to that of unchallenged shrimp at 24 h. In the gills challenged with WSSV, the FcTRX protein was up-regulated from 6 h to 24 h. Our research indicated its possible role in the anti-WSSV innate immunity of shrimps.

Abstract
The techniques of homology cloning and anchored PCR were used to clone the peroxiredoxin (Prx) gene from black tiger shrimp (Penaeus monodon). The full length cDNA of black tiger shrimp Prx (PmPrx) contained a 5' untranslated region (UTR) of 51 bp, an ORF (open reading frame) of 582 bp encoding a polypeptide of 193 amino acids with an estimated molecular mass of 22.15 kDa and a 3' UTR of 948 bp. Sequence comparison showed that PmPrx shared higher identities with Prx IVs than that with other isoforms of Prx, indicating PmPrx was a member of the Prx IV family. A quantitative reverse transcriptase Real-Time PCR (qRT-PCR) assay was developed to assess the mRNA expression of PmPrx in different tissues and the temporal expression of PmPrx in the hepatopancreas challenged by lipopolyssacharide (LPS). Higher-level mRNA expression of PmPrx was detected in the tissues of hepatopancreas, gonad and heart. The expression of PmPrx in the hepatopancreas was up regulated after stimulated by LPS. The results indicated that PmPrx was a constitutive and inducible expressed protein and could be induced by LPS.

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
Peroxiredoxin is a superfamily of antioxidative proteins that play important roles in protecting organisms against the toxicity of reactive oxygen species (ROS). In this study, the full-length cDNA encoding peroxiredoxin 6 (designated EsPrx6) was cloned from Chinese mitten crab Eriocheir sinensis by using rapid amplification of cDNA ends (RACE) approaches. The full-length cDNA of EsPrx6 was of 1076 bp, containing a 5' untranslated region (UTR) of 69 bp, a 3' UTR of 347 bp with a poly (A) tail, and an open reading frame (ORF) of 660 bp encoding a polypeptide of 219 amino acids with the predicted molecular weight of 24 kDa. The conserved Prx domain, AhpC domain and the signature of peroxidase catalytic center identified in EsPrx6 strongly suggested that EsPrx6 belonged to the 1-Cys Prx subgroup. Quantitative real-time RT-PCR was employed to assess the mRNA expression of EsPrx6 in various tissues and its temporal expression in haemocytes of crabs challenged with Listonella anguillarum. The mRNA transcript of EsPrx6 could be detected in all the examined tissues with highest expression level in hepatopancreas. The expression level of EsPrx6 in haemocytes was down-regulated after bacterial challenge and significantly decreased compared to the control group at 12h. As time progressed, the expression level began to increase but did not recover to the original level during the experiment. The results suggested the involvement of EsPrx6 in responses against bacterial infection and further highlighted its functional importance in the immune system of E. sinensis.
