The lysosomal cysteine protease cathepsin C plays a pivotal role in regulation of inflammatory and immune responses. However, the function of fish cathepsin C in virus replication remains largely unknown. In this study, cathepsin C gene (Ec-CC) was cloned and characterized from orange-spotted grouper, Epinephelus coioides. The full-length Ec-CC cDNA was composed of 2077 bp. It contained an open reading frame (ORF) of 1374 bp and encoded a 458-amino acid protein which shared 89% identity to cathepsin C from bicolor damselfish (Stegastes partitus)...

Chemokine receptor Cxcr4 evolved two paralogs in the teleost lineage. However, cxcr4a and cxcr4b have been characterized only in a few species. In this study, we identified two cxcr4 paralogs from the orange-spotted grouper, Epinephelus coioides . The phylogenetic relationship and gene structure and synteny suggest that the duplicated cxcr4a/b should result from the teleost-specific genome duplication (Ts3R). The teleost cxcr4 gene clusters in two paralogous chromosomes exhibit a complementary gene loss/retention pattern...

Complement 1 inhibitor (C1INH) serving as a multifunctional factor can participate in the regulation of complement cascades and attenuate the activation of various proteases. In this study, we obtained EcC1INH cDNA and the tissue-specific analysis indicate that the highest expression level of EcC1INH mRNA was detected in liver. Moreover, Vibrio alginolyticus challenge can significantly increase EcC1INH mRNA expression in liver and kidney. N-terminal domain of EcC1INH could decrease LPS binding activity to cell surface, while loss of positively charged residues (PCRs) Arg21, His22, Lys50, Arg61 in N-terminal domain of EcC1INH can significantly reduce its interaction with LPS...

Describing the spatial patterns of benthic coastal habitats and investigating how those patterns affect the ecology of inhabiting species is a main objective of seascape ecology. Within this emerging discipline spatial scale is a principal topic. Different spatial scales inform on different characteristics of the habitat and therefore the relation between species and their habitats would be better defined when observed at multiple levels of spatial scale. Here we apply a multiscale seascape approach to investigate the habitat preferences of juvenile and adult individuals of dusky grouper (Epinephelus marginatus) in a Mediterranean marine protected area...

Transforming growth factor-β activated kinase 1 (TAK1) is a crucial signal transducer in multiple signaling pathways. TAK1 binds TAB1, TAB2, and TAB3, which act as activators and adaptors that specifically regulate the activation of TAK1. To date, the role of TABs is largely unknown in fish. In the present study, a TAB1 cDNA sequence was identified in grouper (Epinephelus coioides), and designated EcTAB1. The full-length open reading frame of EcTAB1 is 1, 521 bp; it encodes 506 amino acids that contains an N-terminal PP2C domain...

In this study, we systematically investigated the process of sex reversal induced by 17-methyltestosterone (MT) feeding and MT-feeding withdrawal at the ovary differentiation stage in orange-spotted groupers, Epinephelus coioides . Gonadal histology showed that MT feeding induced a precocious sex reversal from immature ovaries to testes, bypassing the formation of an ovarian cavity, and MT-feeding withdrawal led to an ovarian fate. In both the MT feeding and MT-feeding withdrawal phases, cytochrome P450 family 11 subfamily B ( cyp11b ) gene expression and serum 11-KT levels were not significantly changed, suggesting that the MT-treated fish did not generate endogenous steroids, even though active spermatogenesis occurred...

The giant grouper Epinephelus lanceolatus is an ecologically vulnerable species with high market demand. However, efforts to improve larval husbandry are hindered by a lack of knowledge surrounding larval developmental physiology. To address this shortfall, a transcriptomic approach was applied to larvae between 1 and 14 days post hatch (dph) to characterise the molecular ontogenesis of genes that influence appetite and digestion. Appetite regulating factors were detected from 1 dph, including neuropeptide Y, nesfatin-1, cocaine and amphetamine regulated transcript, cholecystokinin and pituitary adenylate cyclase activating peptide and the expression level of several genes changed sharply with the onset of exogenous feeding...

Chemokines comprise a group of small molecular weight (6-14 kDa) cytokines; chemokine receptors are a superfamily of seven transmembrane domain G-coupled receptors. Both chemokines and their receptors have important roles in immune surveillance, inflammation, and development. Recently, 9 CXC chemokine ligands (CXCLs) and 8 CXC chemokine receptors (CXCRs) were identified and cloned from orange-spotted grouper (Epinephelus coioides) and annotated by phylogenetic and syntenic analyses. We detected mRNA transcripts for CXCLs and CXCRs in healthy tissues of E...

Cytochrome P450 aromatase (P450arom), which is encoded by cyp19a1a, can convert androgen to estrogen. Therefore, P450arom is important in gonadal differentiation and maintenance. In this study, we analyzed the expression and DNA methylation of cyp19a from Chinese sea perch Lateolabrax maculatus (sp. cyp19a1a). The sp. cyp19a1a gene consists of 9 exons, but only 3.5 kb, being smaller than the human cyp19a1a, as a result of small introns. The sp. cyp19a1a protein contains 518 amino acid residues and evolutionarily conserved domains and is clustered in the teleost subfamily on the phylogenetic tree...

Small ubiquitin-related modifiers (SUMOs) are post-translationally conjugated to other proteins and are essential regulators of a wide range of cellular processes. Covalent attachment of SUMO requires an enzymatic cascade consisting of a single E1-activating enzyme (Aos1 and Uba2 heterodimer), a single E2-conjugating enzyme (Ubc9), and one of several E3 ligases that facilitate transfer of SUMO from Ubc9 to the substrate. In the present study, the Aos1 and Uba2 homologues (EcAos1 and EcUba2) from the orange-spotted grouper (Epinephelus coioides) were cloned and their possible roles in fish immunity were analyzed...
