Abstract
The genus Hippocampus is a multi-origin animal species with high medicinal and healthcare values. About 57 species of Hippocampus spread worldwide, of which about 14 species can be used as medicine, showing anti-oxidation, anti-inflammation, anti-depressant, anti-hypertension, anti-prostatic hyperplasia, antivirus, anti-apoptotic, antifatigue, and so on. And those pharmacological effects are mainly related to their active ingredients, including amino acids, abundant proteins (peptides and oligopeptides), fatty acids, nucleosides, steroids, and other small molecular compounds. The main means of authentication of Hippocampus species are morphological identification, microscopic identification, thin layer chromatography method, fingerprint method and genomics method. This review will provide useful insight for exploration, further study and precise medication of Hippocampus in the future.

Thioredoxin domain-containing protein 12 (TXNDC12) in red spotted grouper (Epinephelus akaara): Molecular characteristics, disulfide reductase activities, and immune responses. FISH & SHELLFISH IMMUNOLOGY 2023; 132:108449. [PMID: 36436687 DOI: 10.1016/j.fsi.2022.11.037] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 11/20/2022] [Accepted: 11/21/2022] [Indexed: 06/16/2023]
Abstract
Thioredoxins are small ubiquitous redox proteins that are involved in many biological processes. Proteins with thiol-disulfide bonds are essential regulators of cellular redox homeostasis and diagnostic markers for redox-dependent diseases. Here, we identified and characterized the thioredoxin domain-containing protein 12 (EaTXNDC12) gene in red spotted grouper (Epinephelus akaara), evaluated transcriptional responses, and investigated the activity of the recombinant protein using functional assays. EaTXNDC12 is a 19.22-kDa endoplasmic reticulum (ER)-resident protein with a 522-bp open reading frame and 173 amino acids, including a signal peptide. We identified a conserved active motif (66WCGAC70) and ER retention motif (170GDEL173) in the EaTXNDC12 amino acid sequence. Relative EaTXNDC12 mRNA expression was analyzed using 12 different tissues, with the highest expression seen in brain tissue, while skin tissue showed the lowest expression level. Furthermore, mRNA expression in response to immune challenges was analyzed in the head kidney, blood, and gill tissues. EaTXNDC12 was significantly modulated in response to bacterial endotoxin lipopolysaccharide (LPS), nervous necrosis virus (NNV), and polyinosinic:polycytidylic acid (poly(I:C)) challenges in all of the tested tissues. Recombinant EaTXNDC12 (rEaTXNDC12) displayed antioxidant ability in an insulin reductase assay, and a capacity for free radical inhibition in a 2,2-diphenyl-1-picryl-hydrazyl-hydrate assay. In addition, a DNA nicking assay revealed that purified rEaTXNDC12 exhibited concentration-dependent DNA protection activity, while results from 2-hydroxyethyl disulfide and L-dehydroascorbic assays indicated that rEaTXNDC12a possesses reducing ability. Furthermore, fathead minnow (FHM) cells transfected with EaTXNDC12-pcDNA demonstrated significantly upregulated cell survival against H2O2-induced apoptosis. Collectively, the results of this study strengthen our knowledge of EaTXNDC12 with respect to cellular redox hemostasis and immune regulation in Epinephelus akaara.

Hypoxia Affects the Antioxidant Activity of Glutaredoxin 3 in Scylla paramamosain through Hypoxia Response Elements. Antioxidants (Basel) 2022; 12:antiox12010076. [PMID: 36670937 PMCID: PMC9855028 DOI: 10.3390/antiox12010076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 12/18/2022] [Accepted: 12/27/2022] [Indexed: 12/31/2022] Open
Abstract
Hypoxia is a major environmental stressor that can damage the oxidation metabolism of crustaceans. Glutaredoxin (Grx) is a key member of the thioredoxin superfamily and plays an important role in the host's defense against oxidative stress. At present, the role of Grx in response to hypoxia in crustaceans remains unclear. In this study, the full-length cDNA of Grx3 (SpGrx3) was obtained from the mud crab Scylla paramamosain, which contains a 129-bp 5' untranslated region, a 981-bp open reading frame, and a 1,183-bp 3' untranslated region. The putative SpGrx3 protein contains an N-terminal thioredoxin domain and two C-terminal Grx domains. SpGrx3 was expressed in all tissues examined, with the highest expression in the anterior gills. After hypoxia, SpGrx3 expression was significantly up-regulated in the anterior gills of mud crabs. The expression of Grx2 and glutathione S-transferases was decreased, while the expression of glutathione peroxidases was increased following hypoxia when SpGrx3 was silenced in vivo. In addition, the total antioxidant capacity of SpGrx3-interfered mud crabs was significantly decreased, and the malondialdehyde content was significantly increased during hypoxia. The subcellular localization data indicated that SpGrx3 was predominantly localized in the nucleus when expressed in Drosophila Schneider 2 (S2) cells. Moreover, overexpression of SpGrx3 reduced the content of reactive oxygen species in S2 cells during hypoxia. To further investigate the transactivation mechanism of SpGrx3 during hypoxia, the promoter region of the SpGrx3 was obtained by Genome Walking and three hypoxia response elements (HREs) were predicted. Dual-luciferase reporter assay results demonstrated that SpGrx3 was likely involved in the hypoxia-inducible factor-1 (HIF-1) pathway during hypoxia, which could be mediated through HREs. The results indicated that SpGrx3 is involved in regulating the antioxidant system of mud crabs and plays a critical role in the response to hypoxia.

Role of rockfish (Sebastes schlegelii) glutaredoxin 1 in innate immunity, and alleviation of cellular oxidative stress: Insights into localization, molecular characteristics, transcription, and function. Comp Biochem Physiol B Biochem Mol Biol 2020; 243-244:110432. [PMID: 32119919 DOI: 10.1016/j.cbpb.2020.110432] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Revised: 02/21/2020] [Accepted: 02/25/2020] [Indexed: 12/30/2022]
Abstract
Glutaredoxins are a group of heat stable oxidoreductases ubiquitously found in prokaryotes and eukaryotes. They are widely known for GSH (glutathione)-dependent protein disulfide reduction and cellular redox homeostasis. This study was performed to identify and characterize rockfish (Sebastes schlegelii) glutaredoxin 1 (SsGrx1) at molecular, transcriptional, and functional levels. The coding sequence of SsGrx1 was 318 bp in length and encoded a protein containing 106 amino acids. The molecular weight and theoretical isoelectric point of the putative SsGrx1 protein were 11.6 kDa and 6.71 kDa, respectively. The amino acid sequence of SsGrx1 comprised a CPYC redox active motif surrounded by several conserved GSH binding sites. The modeled protein structure was found to consist of five α-helices and four β-sheets, similar to human Grx1. SsGrx1 showed a tissue specific expression in all the tissues tested, with the highest expression in the kidney. Immune stimulation by lipopolysaccharides (LPS), polyinosinic:polycytidylic acid (polyI:C), and Streptococcus iniae (S. iniae) could significantly modulate the SsGrx1 expression pattern in the blood and gills. Analysis of its subcellular localization disclosed that SsGrx1 was prominently localized in the cytosol. Recombinant SsGrx1 (rSsGrx1) exhibited significant activity in insulin disulfide reduction assay and HED (β-Hydroxyethyl Disulfide) assay. Furthermore, transient overexpression of SsGrx1 in FHM (fathead minnow) cells significantly enhanced cell survival upon H2O2-induced apoptosis. Collectively, our findings strongly suggest that SsGrx1 plays a crucial role in providing rockfish immune protection against pathogens and oxidative stress.
