Copper/Zinc Superoxide Dismutase from the Crocodile Icefish Chionodraco hamatus: Antioxidant Defense at Constant Sub-Zero Temperature. Antioxidants (Basel) 2020; 9:antiox9040325. [PMID: 32316382 PMCID: PMC7222407 DOI: 10.3390/antiox9040325] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 04/13/2020] [Accepted: 04/14/2020] [Indexed: 12/11/2022] Open
Abstract
In the present study, we describe the purification and molecular characterization of Cu,Zn superoxide dismutase (SOD) from Chionodraco hamatus, an Antarctic teleost widely distributed in many areas of the Ross Sea that plays a pivotal role in the Antarctic food chain. The primary sequence was obtained using biochemical and molecular biology approaches and compared with Cu,Zn SODs from other organisms. Multiple sequence alignment using the amino acid sequence revealed that Cu,Zn SOD showed considerable sequence similarity with its orthologues from various vertebrate species, but also some specific substitutions directly linked to cold adaptation. Phylogenetic analyses presented the monophyletic status of Antartic Teleostei among the Perciformes, confirming the erratic differentiation of these proteins and concurring with the theory of the "unclock-like" behavior of Cu,Zn SOD evolution. Expression of C. hamatus Cu,Zn SOD at both the mRNA and protein levels were analyzed in various tissues, highlighting the regulation of gene expression related to environmental stress conditions and also animal physiology. The data presented are the first on the antioxidant enzymes of a fish belonging to the Channichthyidae family and represent an important starting point in understanding the antioxidant systems of these organisms that are subject to constant risk of oxidative stress.

FISH & SHELLFISH IMMUNOLOGY 2019; 90:363-375. [PMID: 30974219 DOI: 10.1016/j.fsi.2019.04.016] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 03/28/2019] [Accepted: 04/05/2019] [Indexed: 06/09/2023]
Abstract
Superoxide dismutases (SODs) are important antioxidant enzymes that occur in virtually all oxygen-respiring organisms, and copper/zinc SOD (Cu/ZnSOD) is one of the most important SODs. In the present study, Macrobrachium rosenbergii Cu/Zn-SOD was expressed in a yeast eukaryotic system. The open reading frame (ORF) of MrCu/ZnSOD was cloned into the plasmid vector pHAC181, and the recombinant plasmid was integrated into the downstream region of the GAL1 promoter in Saccharomyces cerevisiae strain GAL1-ScRCH1 via homologous recombination. The resulting recombinant MrCu/ZnSOD consisted of a 3 × HA-tag at its C-terminal. Via western blot, the molecular weight of the recombinant MrCu/ZnSOD was estimated at about 30 kDa. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of this recombinant MrCu/ZnSOD ranged from 0.556 to 0.840 μM, and from 0.967 to 2.015 μM, respectively. The recombinant MrCu/ZnSOD protein was able to agglutinate four Gram-negative bacterial strains, as well as two of three Gram-positive strains (except Staphylococcus aureus). This demonstrated that the recombinant protein possessed some antimicrobial activity against certain Gram-positive and Gram-negative bacteria. M. rosenbergii were fed with the recombinant yeast strain MrCu/ZnSOD for 4 weeks and then challenged with the most common crustacean pathogen, Vibrio parahaemolyticus. This group of prawns presented lower mortality, higher enzymatic activity, and higher expression of the mRNA of immune-related genes than that in the control groups. Taken together, these results suggest that MrCu/ZnSOD is an antioxidant enzyme and antimicrobial peptide involved in the crustacean innate immune system and offers protection to the host against pathogenic bacteria.

Identification and mRNA expression of antioxidant enzyme genes associated with the oxidative stress response in the Wuchang bream (Megalobrama amblycephala Yih) in response to acute nitrite exposure. Comp Biochem Physiol C Toxicol Pharmacol 2014; 159:69-77. [PMID: 24100052 DOI: 10.1016/j.cbpc.2013.09.005] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2013] [Revised: 09/18/2013] [Accepted: 09/19/2013] [Indexed: 11/20/2022]
Abstract
Aquatic organisms possess cellular detoxification systems to deal with pollutants. To explore the influence of reactive oxygen species (ROS) generated in response to nitrite on oxidative stress defenses and the antioxidant system in Megalobrama amblycephala, the full length cDNA sequences were determined for three antioxidant-related genes, namely catalase (MaCAT), selenium-dependent glutathione peroxidase (MaGPx1) and Cu/Zn superoxide dismutase (MaCu/Zn-SOD). Encoded polypeptides that exhibited high identity and similarity with corresponding proteins in other fish species. Expression levels of these antioxidant genes were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) technique. MaCAT, MaGPx1 and MaCu/Zn-SOD expression was greatest in the liver and qRT-PCR was used to assess expression of these genes in juvenile fish during 72 h of exposure to 15 mg/L nitrite. Prolonged nitrite exposure resulted in the formation of excess ROS that caused oxidative damage to lipids and proteins and reduced the activities of antioxidant enzymes. Fish exposed to nitrite also showed liver damage. This study provides transcriptional data for MaCAT, MaGPx1 and MaCu/Zn-SOD that suggest expression is related positively with oxidative stress induced by nitrite exposure, indicating that imbalance between ROS and antioxidant defenses is one mechanism underlying nitrite toxicity in M. amblycephala.

Abstract
Antioxidant enzymes are known to protect living organisms against the oxidative stress risk, also induced by metals. In the present study, we describe the purification and molecular characterization of two Cu,Zn superoxide dismutases (SODs), referred to as Ci-SODa and Ci-SODb, from Ciona intestinalis, a basal chordate widely distributed in temperate shallow seawater. The putative amino acid sequences were compared with Cu,Zn SODs from other metazoans and phylogenetic analyses indicate that the two putative Ci-SODs are more related to invertebrate SODs than vertebrate ones. Both phylogenetic and preliminary homology modeling analyses suggest that Ci-SODa and Ci-SODb are extracellular and intracellular isoform, respectively. The mRNA of the two Cu,Zn SODs was localized in hemocytes and in ovarian follicular cells, as revealed by in situ hybridization. The time course of SOD mRNA levels in the presence of three different metals showed upregulation of ci-soda and inhibition of ci-sodb. Spectrophotometric analysis confirms the presence of SOD activity in Ciona tissues. Our in silico analyses of the ci-soda promoter region revealed putative consensus sequences similar to mammalian metal-responsive elements (MRE), suggesting that the transcription of these genes directly depends on metals. These data emphasize the importance of complex metal regulation of ci-soda and ci-sodb transcription, as components of an efficient detoxification pathway allowing the survival of C. intestinalis in continued, elevated presence of metals in the environment.

Abstract
Hexavalent chromium (Cr(6+)) is a common pollutant transient metal with high toxicity in the environment. The toxicological effects partly result from oxidative damage due to the production of excessive reactive oxygen species (ROS) in the reductive process of Cr(6+). To explore the influence of ROS induced directly by Cr(6+) on the oxidative stress generation and antioxidant system, the full length cDNAs of antioxidant-related genes cat, gpx1 and Cu/Zn-sod were successfully acquired from pengze crucian carp first and analyzed. Furthermore, the mRNA expression of the antioxidant genes encompassing catalase (cat), copper/zinc superoxide dismutase (Cu/Zn-sod) and glutathione peroxidase (gpx1), antioxidant enzyme activities of CAT, SOD, and GPx and total protein content were further studied in the gill, intestine and liver of pengze crucian carp (Carassius auratus var. Pengze) juveniles upon acute exposure to Cr(6+) at concentrations of 0.1, 1.0, 10 and 100 mg/L for 4 days. Differential significant changes of the antioxidant enzymes and gene expression were observed in different tissues. The findings contribute to better understanding the antioxidant mechanisms induced by Cr(6+) and selecting the organic-specific sensitive biomarkers to monitor the safety of the aquatic ecosystem.

Abstract
Copper Zinc Superoxide dismutase (CuZnSOD) is the family of most important antioxidant metalloenzymes that protects tissues from damage by reactive oxygen species (ROS). In the present study, the intracellular copper zinc SOD from the Asian seabass Lates calcarifer (Lc-icCuZnSOD) was identified by RNA ligase mediated rapid amplification of cDNA ends (RLM-RACE) technique. The full-length cDNA of Lc-icCuZnSOD consisted of 809 nucleotides with an open-reading frame of 465 bp encoding 154 amino acids and N-Glycosylation site (NVTA) within. The predicted molecular mass of the protein is 15.84 kDa with an estimated pI of 5.52. The deduced amino acid sequence of Lc-icCuZnSOD shared high degree of homology with known CuZnSODs from other species. CuZn binding sites (H47, H49, H64, and H121 for Cu(2+) and H72, H81, and ASP84 for Zn(2+)), two cysteine residues (aa 58 and 147) that form a disulfide bond, and CuZnSOD family signature sequences (GFHVHAFGDNT, aa 45-55 and GNAGGRLACGVI, aa 139-150) were highly conserved among fish species. Temporal and tissue specific expression of Lc-icCuZnSOD was significantly differentially altered in Asian seabass challenged with Vibrio anguillarum indicating possible role in antioxidant activities involved in the innate immune defense mechanisms.

Abstract
Copper/zinc superoxide dismutase (Cu,Zn-SOD) cDNA and manganese superoxide dismutase (Mn-SOD) cDNA were first cloned from silver carp Hypophthalmichthys molitrix using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) method. The open reading frame (ORF) of Cu,Zn-SOD is 465 bp and encodes a 154 amino acids (aa) protein, whereas the ORF of Mn-SOD is 675 bp and encodes a 224 aa protein. Multiple polypeptide sequence alignment showed high identity both of Cu,Zn-SOD (70-87%) and Mn-SOD (80-96%) with the species compared. Both Cu,Zn-SOD and Mn-SOD were detected in heart, brain, liver, kidney, spleen, muscle, gill and blood. Cu,Zn-SOD and Mn-SOD were expressed throughout the embryogenesis, indicating their important roles during embryonic development specially at the cleavage stage. Acute hypoxia suppressed expression of Cu,Zn-SOD and Mn-SOD in liver significantly, up-regulated them in gill relatively, indicating that tissue-specific expression of Cu,Zn-SOD and Mn-SOD is an important stress response adapted to hypoxia.

The amino acid and cDNA sequences have been obtained using both biochemical and molecular biology approaches and are compared with Cu,Zn SODs from other fishes. Assessment of the primary sequences highlights that the catalytically important residues are fully conserved in Cu,Zn SOD from T. bernacchii. Phylogenetic analyses performed on Cu,Zn SOD amino acid sequences permit speculation regarding the evolution of this protein. In particular, the data confirms the erratic differentiation of these proteins and concurs with the theory of the "unclock-like" behaviour of Cu,Zn SOD evolution.

Abstract
A copper/zinc superoxide dismutase (Cu,Zn-SOD) cDNA was cloned from the hepatopancreas of giant freshwater prawn Macrobrachium rosenbergii using reverse transcription-polymerase chain reaction (RT-PCR) by degenerate primers. Both 3'- and 5'-regions were isolated by the rapid amplification of cDNA ends method. Analysis of nucleotide sequence revealed that the Cu,Zn-SOD cDNA clone consists of 845 bp with an open reading frame of 603 bp encoding a protein of 201 amino acids with a 22 amino acid signal peptide. The calculated molecular mass of the mature proteins (179 amino acids) is 21 kDa with an estimated pI of 4.75. Two putative N-glycosylation sites, NXT and NXS, were observed in the Cu,Zn-SOD. Four conserved amino acids responsible for binding copper (H86, H89, H106 and H163) and four conserved amino acids responsible for binding zinc (H106, H114, H123 and D126) were observed. Sequence comparison showed that the Cu,Zn-SOD deduced amino acid sequence of M. rosenbergii has similarity of 60% and 64% to that of freshwater crayfish Pacifastacus leniusculus ecCu,Zn-SOD and blue crab Callinectes sapidus ecCu,Zn-SOD, respectively. Quantitative real-time RT-PCR analysis showed that Cu,Zn-SOD transcripts in haemocytes of M. rosenbergii increased 3h and 6h after injection of Lactococcus garvieae, whereas Cu,Zn-SOD transcripts decreased in the hepatopancreas 3h after L. garvieae injection.
