Antioxidants (Basel) 2023; 13:18. [PMID: 38275638 PMCID: PMC10812468 DOI: 10.3390/antiox13010018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 11/27/2023] [Accepted: 11/28/2023] [Indexed: 01/27/2024] Open
Abstract
Fish possess numerous enzymatic antioxidant systems as part of their innate immunity. These systems have been poorly studied in Labeo rohita (rohu). The present study characterized and investigated the role of antioxidant genes in the defence mechanisms against two types of stressors, including infection and ammonia stress. Four key genes associated with antioxidant activity-catalase, glutathione peroxidase, glutathione S-transferase, and CuZn superoxide dismutase were successfully cloned and sequenced. These genes were found to be expressed in different tissues and developmental stages of rohu. The expression levels of these antioxidant genes in the liver and anterior kidney tissues of rohu juveniles were modulated in response to bacterial infection (Aeromonas hydrophila), parasite infection (Argulus siamensis), poly I:C stimulation and ammonia stress. Additionally, the recombinant proteins derived from these genes exhibited significant antioxidant and antibacterial activities. These proteins also demonstrated a protective effect against A. hydrophila infection in rohu and had an immunomodulatory role. Furthermore, indirect ELISA assay systems were developed to measure these protein levels in healthy as well as A. hydrophila and ammonia-induced rohu serum. Overall, this study characterized and emphasised the importance of the antioxidant mechanism in rohu's defence against oxidative damage and microbial diseases.

AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2023; 263:106708. [PMID: 37776712 DOI: 10.1016/j.aquatox.2023.106708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 09/21/2023] [Accepted: 09/24/2023] [Indexed: 10/02/2023]
Abstract
Glutathione S-transferase is a crucial phase II metabolic enzyme involved in detoxification and metabolism in aquatic organisms. This study aimed to investigate the regulation of Nrf2/Keap1 pathway on microcystin-induced CpGST-Mu expression and CpGST-Mu resistance to hydrogen peroxide. A mu class GST from Cristaria plicata (CpGST-Mu) was identified. The full-length cDNA was 1026 bp, with an open reading frame of 558 bp. Subcellular localization revealed that CpGST-Mu was localized in cytoplasm. The optimum pH and temperature for the catalytic activity of CpGST-Mu protein was pH 6 and 40 °C, respectively. The results of Real-time quantitative PCR showed that CpGST-Mu mRNA was constitutively expressed in tissues, with the highest expression level in hepatopancreas and the lowest expression level in gill. The mRNA level of CpGST-Mu was significantly increased under the stress of microcystins and hydrogen peroxide. CpGST-Mu had an antagonistic effect on hydrogen peroxide. In the knockdown experiments, the mRNA levels of CpGST-Mu exhibited corresponding changes while Nrf2 and Keap1 genes were individually knocked down. These findings indicated that GST-Mu exhibited antioxidant properties and its expression was regulated by Nrf2/Keap1 signaling pathway. The study provided new information on the function of GST-Mu and could contribute to future studies on how to excrete microcystins in molluscs.

Abstract
Cold causes oxidative stress in living organisms, mainly caused by the accumulation of reactive oxygen species (ROS). In the antioxidant defense systems, Glutathione S-transferases (GSTs) play a vital role in the regulation of detoxification and redox balance of ROS. In this study, the P. canaliculata GST gene family were characterized using a genome-wide search of the conserved domain. Phylogenetic tree and domain composition analysis revealed that 30 PcGSTs belong to seven classes, including five in MAPEG, two in Mu, nine in Omega, 11 in Sigma, one in Rho, Theta and Alpha class, respectively. RNA-seq analysis revealed that most PcGSTs localized in mitochondria highly expressed in hepatopancreas, and most PcGSTs localized in cytoplasm highly expressed in kidney. A total of 12 PcGST genes were significantly up-regulated and PcGST12 was significantly down-regulated after cold acclimation. Ten PcGSTs were identified as DEGs under cold stress after cold acclimation. qRT-PCR revealed that the expression level of five PcGST genes were significantly varied during the cold acclimation. The present study investigated the characterization of the P. canaliculata GST gene family, extending our understanding of GST mediated cold acclimation and cold stress-response mechanisms in this invasive snail.

Glutathione-S-transferase alpha-4 in Hippocampus abdominalis (big-belly seahorse): Molecular characterization, antioxidant properties, and its potent immune response. Comp Biochem Physiol C Toxicol Pharmacol 2021; 240:108917. [PMID: 33141081 DOI: 10.1016/j.cbpc.2020.108917] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 10/12/2020] [Accepted: 10/18/2020] [Indexed: 01/23/2023]
Abstract
Glutathione-S-transferase (GST) is a key enzyme in the phase-II detoxification process and is a biomarker of oxidative stress. In this study, we analyzed the molecular, biochemical, and antioxidant properties of GST alpha-4 from Hippocampus abdominalis (HaGSTA-4). Also, the spatial and temporal expression of HaGSTA-4 upon immune challenge with abiotic and biotic stimulants were evaluated. The HaGSTA-4 ORF encodes 223 amino acids with a molecular weight of 25.7 kDa, and an estimated isoelectric point (pI) of 8.47. It consists of the GST_C superfamily and thioredoxin-like superfamily domain. The phylogenetic tree revealed that HaGSTA-4 is evolutionarily conserved with its GST alpha class counterparts. From pairwise alignment, the highest values of identity (78.5%) and similarity (85.7%) were with Parambassis ranga GSTA-4. Protein rHaGSTA-4 exhibited the highest conjugation activity towards 1-chloro-2,4-dinitrobenzene (CDNB) at pH 7 and 20 °C. A disk diffusion assay showed that rHaGSTA-4 significantly protects cells from the stress of exposure to ROS inducers such as CuSO4, CdCl2, and ZnCl2. Furthermore, overexpressed HaGSTA-4 defended cells against oxidative stress caused by H2O2; evidence of selenium-independent peroxidase activity. From qPCR, the tissue-specific expression profile demonstrates that HaGSTA-4 is most highly expressed in the kidney, followed by the intestine and stomach, among fourteen different tissues extracted from healthy seahorses. The mRNA expression profile of HaGSTA-4 upon immune challenge varied depending on the tissue and the time after challenge. Altogether, this study suggests that HaGSTA-4 may be involved in protection against oxidative stress, in immune defense regulation, and xenobiotic metabolism.

Abstract
Glutathione S-transferases (GSTs) play important roles in immunity by protecting organisms against the damage of reactive oxygen species (ROS). In this study, a pi-class GST cDNA sequence was first cloned from noble scallop Chlamys nobilis (named CnGSTp). The full length cDNA of CnGSTp was 922 bp, encoding a cytosolic protein of 202 amino acids residues, with predicted molecular masses of 23.1 kDa. Then an acute Vibrio Parahaemolyticus challenge experiment was conducted by using the Golden and Brown noble scallops with different total carotenoids content (TCC), and CnGSTp expression level, TCC and ROS level was separately determined. The results showed that ROS and CnGSTp expression levels were significantly up-regulate under Vibrio Parahaemolyticus challenge than the control group (P < 0.05). The Golden scallops showed significantly higher CnGSTp expression level and lower ROS level in hemocytes than the Brown ones (P < 0.05). Moreover, there is a significantly positive correlation between TCC and ROS in the Golden scallops. The present results revealed that CnGSTp plays important roles in immune response and carotenoids play assistant roles in antioxidant defense system under pathogenic stress in the noble scallop.

Abstract
Glutathione S-transferases (GSTs) are essential enzymes for the bioactivation of xenobiotics through the conjugation of the thiol group of glutathione (GSH). In this study, a kappa class of GST was identified from the big belly seahorse (Hippocampus abdominalis) (HaGSTκ1) and its biochemical and functional properties were analyzed. HaGSTκ1 has 231 amino acids encoded by a 696 bp open reading frame (ORF). The protein has a predicted molecular mass of 26.04 kDa and theoretical isoelectric point (pI) of 8.28. It comprised a thioredoxin domain, disulfide bond formation protein A (DsbA) general fold, and Ser15 catalytic site as well as GSH-binding and polypeptide-binding sites. Phylogenetic analysis revealed that HaGSTκ1 is closely clustered with the kappa class of GSTs from teleost fishes. The recombinant (rHaGSTκ1) protein exhibited activity toward 1-chloro-2,4-dinitrobenzene (CDNB), 4-nitrobenzyl (4-NBC), and 4-nitrophenethyl bromide (4-NPB) but not 1,2-dichloro-4-nitrobenzene (DCNB). The optimum pH and temperature were 8 and 30 °C, respectively, for the catalysis of CDNB and the universal substrate of GSTs. The rHaGSTκ1 activity was efficiently inhibited in the presence of Cibacron blue (CB) as compared with hematin. Most prominent expression of HaGSTκ1 was observed in the liver and kidney among the fourteen different tissues of normal seahorse. After challenge with lipopolysaccharide (LPS), polyinosinic-polycytidylic (poly I:C), gram-negative Edwardsiella tarda, and gram-positive Streptococcus iniae, HaGSTκ1 expression was significantly modulated in the liver and blood tissues. Altogether, our study proposes the plausible important role of HaGSTκ1 in innate immunity and detoxification of harmful xenobiotics.

Abstract
Representing a multifunctional complex group of proteins, glutathione S- transferases (GSTs) play a major role in the phase II detoxification process in a wide range of organisms. This study focused on the potential detoxification ability of disk abalone (Haliotis discus discus) GST theta (AbGST-θ) under different stress conditions with special reference to post immune challenges. Characterization of AbGST-θ revealed with 226 amino acids, 26.6 kDa of predicted molecular mass and 8.9 of theoretical isoelectric point. As illustrated in the multiple sequence alignment, eight glutathione binding sites (G-sites) and ten substrate binding sites (H-sites) were identified in well-distinct N-terminal and C-terminal domains of AbGST-θ, respectively. AbGST-θ exhibited its highest sequence identity with Mizuhopecten yessoensis (59.1%) and the phylogenetic tree clearly positioned AbGST-θ with pre-defined GST-θ molluscan homologues. The AbGST-θ was highly expressed in the digestive tract of un-challenged abalones. Upon administering the challenge experiment, AbGST-θ showed significant modulations in their transcriptional levels depending on the time and the tissue type. The optimum temperature was 37 °C and optimum pH was 7.5 for AbGST-θ. The determined enzyme kinetic parameters of AbGST-θ showed low affinity towards 1-Chloro-2,4-dinitrobenzene (CDNB) and glutathione (GSH) as substrates. Nonetheless, with Cibacron blue IC50 (half maximal inhibitory concentration) was calculated to be 0.08 μM while observing 100% inhibition with 100 μM. Furthermore, AbGST-θ resulted in significant protection ability towards H2O2, CdCl2, and ZnCl2 in the disk diffusion assay. Collectively, this study provides evidences for the detoxification ability and the immunological host defensive capability of AbGST-θ in disk abalone.

Abstract
This study compares the role of hepatic cytosolic glutathione transferases (cGST) isoforms of three different bivalve species to a Microcystis aeruginosa extract and purified MC-LR exposure (both at 150 μg MC-LR L-1) for 24 h. Characterization and alterations of the cytosolic GST activities in Mytilus galloprovincialis, Ruditapes philippinarum and Corbicula fluminea were measured using four class-specific substrates and changes in individual GST isoforms expression were achieved by a subsequent two-dimensional electrophoresis analysis. Evaluation of cGST activity basal levels using the four class-specific substrates denoted quantitative differences between the three bivalves. Purified MC-LR did not induce any significant response from bivalves. On the other hand, cell extracts caused significant alterations according to bivalves and substrates. Among the three bivalves, only R. philippinarum showed a significant induction of cGST activity using generic 1-chloro-2,4-dinitrobenzene (CDNB) substrate. However, no significant alterations were detected in these clams by cell extracts using the other specific substrates. In contrast, C. fluminea revealed significant induction of cGST activity when using 3,4-dichloronitrobenzene (DCNB) and ethacrynic acid (EA). In M. galloprovincialis, cell extracts promoted a significant decrease of cGST activity when using EA substrate. Altered protein expression was quantitatively detected upon exposure to cell extracts for one spot in R. philippinarum and another for C. fluminea, both upregulated (2.0 and 8.5-fold, respectively) and identified as a sigma1-class GST in the case of the first. The results showed that the three bivalves presented specific adaptive biotransformation responses to MCs and other cyanobacteria compounds supported by the modulation of distinct cGST classes.

Modulation of immune and antioxidant responses by azinphos-methyl in the freshwater mussel Diplodon chilensis challenged with Escherichia coli. ENVIRONMENTAL TOXICOLOGY AND CHEMISTRY 2017; 36:1785-1794. [PMID: 27600597 DOI: 10.1002/etc.3612] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Revised: 08/04/2016] [Accepted: 09/03/2016] [Indexed: 06/06/2023]
Abstract
The aim of the present study was to characterize the immune response-total hemocyte number, cell type proportion, hemocyte viability, lysosomal membrane stability, phagocytic activity, cellular acid and alkaline phosphatase activity, and humoral bacteriolytic and phenoloxidase activity--in Diplodon chilensis exposed to 0.2 mg/L of azinphos-methyl (AZM), using Escherichia coli as immunological and pro-oxidant challenges. In addition, glutathione-S-transferase and lipid peroxidation thiobarbituric acid reactive substances were analyzed in gill tissue. Mussels from an unpolluted site were treated for 3 d as follows: 1) experimental control; 2) solvent effects control (acetone 0.01%); 3) bacterial challenge effects control (E. coli, 5 cells/mL × 104 cells/mL); 4) pesticide effects control (AZM in acetone); 5) control for combined effects of solvent and bacterial challenge; and 6) exposed to AZM, then challenged with E. coli. The results showed increased granulocyte proportion and phagocytic activity. Partial reversion of deleterious effects of E. coli on lysosomal membranes was observed in mussels exposed to AZM and then challenged with E. coli. Total hemocyte number and humoral bacteriolytic activity were increased only by E. coli challenge. Acid phosphatase activity was increased by both E. coli and AZM, whereas the stimulating effect of E. coli on alkaline phosphatase activity was negatively modulated by AZM. Azinphos-methyl inhibited phenoloxidase activity regardless of the E. coli challenge. Gill glutathione-S-transferase activity was increased by E. coli treatment either alone or pretreated with acetone or AZM and by AZM alone. Thiobarbituric acid reactive substance levels were reduced by AZM alone or combined with the E. coli challenge and by acetone followed by the E. coli challenge. Both acetone and AZM seem to be important modulators of immune and antioxidant responses in D. chilensis. Environ Toxicol Chem 2017;36:1785-1794. © 2016 SETAC.

Abstract
Glutathione S-transferases (GSTs) are the superfamily of multifunctional detoxification isoenzymes and play crucial roles in innate immunity. In the present study, a theta class GST homology was identified from A. japonicus (designated as AjGST-θ) by RACE approaches. The full-length cDNA of AjGST-θ was of 1013 bp encoded a cytosolic protein of 231 amino acids residues. Structural analysis revealed that AjGST-θ processed the characteristic N-terminal GSH-binding site (G-site) and the C-terminal hydrophobic substrate binding site (H-site). Multiple sequence alignment and phylogenetic analysis together supported that AjGST-θ belonged to a new member of theta class GST protein subfamily. Spatial expression analysis revealed that AjGST-θ was ubiquitously expressed in all examined tissues with the larger magnitude in intestine. The Vibrio splendidus challenge in vivo and LPS stimulation in vitro could both significantly up-regulate the mRNA expression of AjGST-θ when compared with control group. The recombinant protein was expressed in Escherichia coli and the purified AjGST-θ showed high activity with GST substrate. Meantime, disc diffusion assay showed that recombinant AjGST-θ protein could markedly improve bacterial growth under Cumene hydroperoxide exposure. More importantly, the recombinant AjGST-θ could effectively prevent primary coelomocytes apoptosis after LPS exposure. Our present findings suggested that AjGST-θ might play significantly roles in the modulation of immune response and protect cells from pathogens infection in A. japonicus.

Comp Biochem Physiol C Toxicol Pharmacol 2016; 189:31-43. [PMID: 27449269 DOI: 10.1016/j.cbpc.2016.07.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Revised: 06/28/2016] [Accepted: 07/16/2016] [Indexed: 10/21/2022]
Abstract
Glutathione S-transferases (GSTs, EC 2.5.1.18) are categorized as phase II enzymes, which form an important multifunctional family associated with a wide variety of catalytic activities. GSTω, GSTρ, and GSTθ are cytosolic GSTs which have been extensively studied in a variety of organisms; however, few studies have focused on teleosts. Those paralogs from black rockfish (Sebastes schlegelii; RfGSTω, RfGSTρ, and RfGSTθ, respectively) were molecularly, biochemically, and functionally characterized to determine their antioxidant extent and protective aptitudes upon pathogenic stress. RfGSTω, RfGSTρ, and RfGSTθ, contained open reading frames of 717bp, 678bp, and 720bp respectively, which encoded respective proteins of 239, 226, and 240 amino acids in length. In silico analysis revealed that all RfGSTs possessed characteristic N-terminal domains bearing glutathione (GSH)-binding sites, and C-terminal domains containing substrate-binding sites. Recombinant RfGSTω (rRfGSTω) catalyzed the conjugation of GSH to dehydroascorbate (DHA), while rRfGSTθ and rRfGSTρ catalyzed to the model GST substrate 1-Chloro-2,4-dinitrobenzene (CDNB). Kinetic analysis revealed variation in Km and Vmax values for each rRfGST, indicating their different conjugation rates. The optimum conditions (pH and temperature) and inhibition assays of each protein demonstrated different optimal ranges showing their wide range of activity as an assembly. RfGSTω and RfGSTθ paralogs demonstrated their antioxidant potential towards H2O2 and heavy metals (Cd, Zn, and Cu) in vitro, while RfGSTρ had an antioxidant potential only towards heavy metals (Zn and Cu). Though all the paralogs were ubiquitously expressed in different magnitudes, RfGSTω was highly expressed in blood, whereas RfGSTρ and RfGSTθ were highly expressed in liver. The mRNA expression of RfGSTω and RfGSTθ, upon Streptococcus iniae and poly I:C stimulation, revealed a significantly up-regulated expression, whereas RfGSTρ mRNA expression was significantly down-regulated. Collectively, our findings suggest that RfGSTω, RfGSTρ, and RfGSTθ paralogs are potent in detoxifying xenobiotic toxics, capable of protecting cells from oxidative stress generated by both H2O2 and heavy metals, and finally, yet importantly, stimulated under pathogenic stress signals.

Cell Stress Chaperones 2016; 21:805-16. [PMID: 27230212 PMCID: PMC5003797 DOI: 10.1007/s12192-016-0705-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Revised: 05/18/2016] [Accepted: 05/20/2016] [Indexed: 12/17/2022] Open
Abstract
Members of the glutathione S-transferase superfamily can protect organisms against oxidative stress. In this study, we characterized an omega glutathione S-transferase from Spodoptera exigua (SeGSTo). The SeGSTo gene contains an open reading frame (ORF) of 744 nucleotides encoding a 248-amino acid polypeptide. The predicted molecular mass and isoelectric point of SeGSTo are 29007 Da and 7.74, respectively. Multiple amino acid sequence alignment analysis shows that the SeGSTo sequence is closely related to the class 4 GSTo of Bombyx mori BmGSTo4 (77 % protein sequence similarity). Homologous modeling and molecular docking reveal that Cys35 may play an essential role in the catalytic process. Additionally, the phylogenetic tree indicates that SeGSTo belongs to the omega group of the GST superfamily. During S. exigua development, SeGSTo is expressed in the midgut of the fifth instar larval stage, but not in the epidermis or fat body. Identification of recombinant SeGSTo via SDS-PAGE and Western blot shows that its molecular mass is 30 kDa. The recombinant SeGSTo was able to protect super-coiled DNA from damage in a metal-catalyzed oxidation (MCO) system and catalyze the 1-chloro-2,4-dinitrobenzene (CDNB), but not 1,2-dichloro-4-nitrobenzene (DCNB), 4-nitrophenethyl bromide (4-NPB), or 4-nitrobenzyl chloride (4-NBC). The optimal reaction pH and temperature were 8 and 50 °C, respectively, in the catalysis of CDNB by recombinant SeGSTo. The mRNA expression of SeGSTo was up-regulated by various oxidative stresses, such as CdCl2, CuSO4, and isoprocarb, and the catalytic activity of recombinant SeGSTo was noticeably inhibited by heavy metals (Cu(2+) and Cd(2+)) and various pesticides. Taken together, these results indicate that SeGSTo plays an important role in the antioxidation and detoxification of pesticides.

Abstract
We investigated the effect of brown ring disease (BRD) development and algal diet on energy reserves and activity of enzymes related to energy metabolism, antioxidant system and immunity in Manila clam, Ruditapes philippinarum. We found that algal diet did not impact the metabolic response of clams exposed to Vibrio tapetis. At two days post-injection (dpi), activities of superoxide dismutase and glutathione peroxidase (GPx) decreased whereas activities of nitric oxide synthase (iNOS) and catalase increased in infected clams, although no clinical signs were visible (BRD-). At 7 dpi, activities of several antioxidant and immune-related enzymes were markedly increased in BRD-likely indicating an efficient reactive oxygen species (ROS) scavenging compared to animals which developed clinical signs of BRD (BRD+). Therefore, resistance to BRD clinical signs appearance was associated with higher detoxification of ROS and enhancement of immune response. This study provides new biochemical indicators of disease resistance and a more comprehensive view of the global antioxidant response of clam to BRD development.

Abstract
A full-length cDNA of a sigma-like glutathione S-transferase (GST) was identified from Hyriopsis cumingii (HcGSTS). The deduced amino acid sequence of HcGSTS was found to comprise 203 amino acid residues and to contain the distinct highly conserved glutathione binding site of N-terminal and the relatively diverse substrate binding site of C-terminal. Alignment analysis and phylogenetic relationship suggested that the HcGSTS is a sigma-class GST. The mRNA of HcGSTS was constitutively expressed in all tested tissues, the strongest expression being in the hepatopancreas. The mRNA expression of HcGSTS was significantly up-regulated (P < 0.05) in all assessed tissues after stimulation of the mussels with peptidoglycan (PGN) and LPS, the only exception being when the gills were challenged with PGN. The expression of HcGSTS mRNA in kidney and foot was also significantly up-regulated (P < 0.05) by microcystin-LR. Recombinant HcGSTS exhibited high activity towards the substrate 1-chloro-2,4-dinitrobenzene. The optimal pH was 8.0 and temperature 35 °C.

Abstract
Skin ulceration syndrome (SUS) is considered to be a major constraint for the stable development of Apostichopus japonicus culture industries. In this study, we investigated protein changes in the coelomocytes of A. japonicus challenged by Vibrio splendidus using isobaric tags for relative and absolute quantification (iTRAQ) over a 96 h time course. Consequently, 228 differentially expressed proteins were identified in two iTRAQs. A comparison of the protein expression profiles among different time points detected 125 proteins primarily involved in response to endogenous stimuli at 24 h. At 48 h, the number of differentially expressed proteins decreased to 67, with their primary function being oxidation reduction. At the end of pathogen infection, proteins responsive to amino acid stimuli and some metabolic processes were classified as the predominant group. Fifteen proteins were differentially expressed at all time points, among which eight proteins related to pathologies in higher animals were shown to be down-regulated after V. splendidus infection: paxillin, fascin-2, aggrecan, ololfactomedin-1, nesprin-3, a disintegrin-like and metallopeptidase with thrombospondin type 1 motif (Adamts7), C-type lectin domain family 4 (Clec4g) and n-myc downstream regulated gene 1 (Ndrg1). To gain more insight into two SUS-related miRNA (miR-31 and miR-2008) targets at the protein level, all 129 down-regulated proteins were further analyzed in combination with RNA-seq. Twelve and eight proteins were identified as putative targets for miR-31 and miR-2008, respectively, in which six proteins (5 for miR-31 and 1 for miR-2008) displayed higher possibilities to be regulated at the level of translation. Overall, the present work enhances our understanding of the process of V. splendidus-challenged sea cucumber and provides a new method for screening miRNAs targets at the translation level.

Abstract
Glutathione S-transferases (GSTs) are enzymes that catalyze xenobiotic metabolism in the phase II detoxification process. GSTs have a potential for use as indicators or biomarkers to assess the presence of organic and inorganic contaminants in aquatic environments. In this study, a full-length cDNA of a mu (μ) class GST (RpGSTμ) was identified from Manila clam (Ruditapes philippinarum) and biochemically characterized. The 1356 bp of the cDNA included an open reading frame of 651 bp encoding a polypeptide of 217 amino acid residues with a molecular mass of 25.04 kDa and an estimated pI of 6.34. Sequence analysis revealed that the RpGSTμ possessed several characteristic features of μ class GSTs, such as a thioredoxin-like N-terminal domain containing binding sites for glutathione (GSH), a C-terminal domain containing substrate binding sites, and a μ loop. The recombinant RpGSTμ (rRpGSTμ) protein exhibited GSH-conjugating catalytic activity towards several substrates, and significantly strong activity was detected against 4-nitrophenethyl bromide (5.77 ± 0.55) and 1-chloro-2,4-dinitrobenzene (CDNB, 3.19 ± 0.05). Kinetic analysis as a function of GSH and CDNB concentrations revealed relatively low Km values of 1.03 ± 0.46 mM and 0.56 ± 0.20 mM, respectively, thereby indicating a GSH-conjugation attributed with high rates. The optimum pH and temperature for the catalytic activity of the rRpGSTμ protein were 7.7 and 37°C, respectively. The effect of two inhibitors, Cibacron blue and hematin, on the activity of rRpGSTμ was evaluated and the IC50 values of 0.65 μM and 9 μM, respectively, were obtained. While RpGSTμ transcripts were highly expressed in gills and hemocytes, a significant elevation in mRNA levels was detected in these tissues after lipopolysaccharide (LPS), polyinosinic-polycytidylic acid (poly I:C) and live bacterial (Vibrio tapetis) challenges. These findings collectively suggest that RpGSTμ functions as a potent detoxifier of xenobiotic toxicants present in the aquatic environment, and that its mRNA expression could be modulated by pathogenic stress signal(s).

Proteomic profiling of cytosolic glutathione transferases from three bivalve species: Corbicula fluminea, Mytilus galloprovincialis and Anodonta cygnea. Int J Mol Sci 2014; 15:1887-900. [PMID: 24473139 PMCID: PMC3958827 DOI: 10.3390/ijms15021887] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2013] [Revised: 12/31/2013] [Accepted: 01/20/2014] [Indexed: 11/16/2022] Open
Abstract
Suspension-feeding bivalves are considered efficient toxin vectors with a relative insensitivity to toxicants compared to other aquatic organisms. This fact highlights the potential role of detoxification enzymes, such as glutathione transferases (GSTs), in this bivalve resistance. Nevertheless, the GST system has not been extensively described in these organisms. In the present study, cytosolic GSTs isoforms (cGST) were surveyed in three bivalves with different habitats and life strategies: Corbicula fluminea, Anodonta cygnea and Mytilus galloprovincialis. GSTs were purified by glutathione-agarose affinity chromatography, and the collection of expressed cGST classes of each bivalve were identified using a proteomic approach. All the purified extracts were also characterized kinetically. Results reveal variations in cGST subunits collection (diversity and properties) between the three tested bivalves. Using proteomics, four pi-class and two sigma-class GST subunits were identified in M. galloprovincialis. C. fluminea also yielded four pi-class and one sigma-class GST subunits. For A. cygnea, two mu-class and one pi-class GST subunits were identified, these being the first record of GSTs from these freshwater mussels. The affinity purified extracts also show differences regarding enzymatic behavior among species. The variations found in cGST collection and kinetics might justify diverse selective advantages for each bivalve organism.

Abstract
Glutathione S-transferases (GSTs) are essential components of the cellular detoxification system because of their capability to protect organisms against the toxicity of reactive oxygen species (ROSs). Four different GSTs (MrMuGST1-MrMuGST4) showing similarities with Mu-type GSTs were cloned from the hepatopancreas of Macrobrachium rosenbergii. These four GSTs have 219, 216, 218 and 219 amino acids in length, respectively. MrMuGST1-MrMuGST4 proteins all have a G-site in the N-terminus and an H-site in the C-terminus. Phylogenetic analysis reveals that four Mu-type GSTs are classified into two different clades (MrMuGST2 one clade; MrMuGST1, MrMuGST3 and MrMuGST4 other clades). Nonetheless, no site under positive selection was detected but rapid evolution was found in the few of MuGST genes. Reverse transcription-polymerase chain reaction (RT-PCR) results showed that MrMuGST1 and MrMuGST2 transcripts were expressed in all detected tissues, however, MrMuGST3 and MrMuGST4 were just mainly expressed in hepatopancreas and intestines. Quantitative RT-PCR analysis showed that MrMuGST1 and MrMuGST2 were down-regulated upon Vibrio anguillarum challenge, whereas MrMuGST3 and MrMuGST4 were quickly up-regulated 2 h after the Vibrio challenge. Our results imply that different Mu-type GSTs may respond to Vibrio challenge with different manners.

FISH & SHELLFISH IMMUNOLOGY 2012; 33:753-765. [PMID: 22789716 DOI: 10.1016/j.fsi.2012.06.024] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2012] [Revised: 06/13/2012] [Accepted: 06/28/2012] [Indexed: 06/01/2023]
Abstract
Superoxide dismutases (SODs), antioxidant metalloenzymes, represent the first line of defense in biological systems against oxidative stress caused by excessive reactive oxygen species (ROS), in particular O(2)(•-). Two distinct members of SOD family were identified from Manila clam Ruditapes philippinarum (abbreviated as RpMnSOD and RpCu/ZnSOD). The structural analysis revealed all common characteristics of SOD family in both RpSODs from primary to tertiary levels, including three MnSOD signatures and two Cu/ZnSOD signatures as well as invariant Mn(2+)- and Cu/Zn(2+)-binding sites in RpMnSOD and RpCu/ZnSOD, respectively. Putative RpMnSOD and RpCu/ZnSOD proteins were predicted to be localized in mitochondrial matrix and cytosol, respectively. They shared 65.2% and 63.9% of identity with human MnSOD and Cu/ZnSOD, respectively. Phylogentic evidences indicated the emergence of RpSODs within molluscan monophyletic clade. The analogous spatial expression profiles of RpSODs demonstrated their higher mRNA levels in hemocytes and gills. The experimental challenges with poly I:C, lipopolysaccharide and Vibrio tapetis illustrated the time-dependent dynamic expression of RpSODs in hemocytes and gills. The recombinant RpMnSOD was expressed in a prokaryotic system and its antioxidant property was studied. The rRpMnSOD exhibited its optimum activity at 20 °C, under alkaline condition (pH 9) with a specific activity of 3299 U mg(-1). These outcomes suggested that RpSODs were constitutively expressing inducible proteins that might play crucial role(s) in innate immunity of Manila clam.
