Collapse of scallop Nodipecten nodosus production in the tropical Southeast Brazil as a possible consequence of global warming and water pollution.

Abstract
Mollusc rearing is a relevant global socioeconomic activity. However, this activity has faced severe problems in the last years in southeast Brazil. The mariculture scallop production dropped from 51,2 tons in 2016 to 10,2 tons in 2022 in the Baia da Ilha Grande (BIG; Rio de Janeiro). However, the possible causes of this collapse are unknown. This study aimed to analyze decadal trends of water quality in Nodipecten nodosus spat and adult production in BIG. We also performed physical-chemical and biological water quality analyses of three scallop farms and two nearby locations at BIG in 2022 to evaluate possible environmental stressors and risks. Scallop spat production dropped drastically in the last five years (2018-2022: mean ± stdev: 0.47 ± 0.45 million). Spat production was higher in colder waters and during peaks of Chlorophyll a in the last 13 years. Reduction of Chlorophyll a coincided with decreasing spat production in the last five years. Warmer periods (>27 °C) of the year may hamper scallop development. Counts of potentially pathogenic bacteria (Vibrios) and Escherichia coli were significantly higher in warmer periods which may further reduce scallop productivity. Shotgun metagenomics of seawater samples from the five studied corroborated these culture-based counts. Vibrios and fecal indicator bacteria metagenomic sequences were abundant across the entire study area throughout 2022. The results of this study suggest the collapse of scallop mariculture is the result of a synergistic negative effect of global warming and poor seawater quality.

Abstract
Haemocytes play a dominant role in shellfish immunity, being considered the main defence effector cells in molluscs. These cells are known to be responsible for many functions, including chemotaxis, cellular recognition, attachment, aggregation, shell repair and nutrient transport and digestion. There are two basic cell types of bivalve haemocytes morphologically distinguishable, hyalinocytes and granulocytes; however, functional differences and specific abilities are poorly understood: granulocytes are believed to be more efficient in killing microorganisms, while hyalinocytes are thought to be more specialised in clotting and wound healing. A proteomic approach was implemented to find qualitative differences in the protein profile between granulocytes and hyalinocytes of the European flat oyster, Ostrea edulis, as a way to evaluate functional differences. Oyster haemolymph cells were differentially separated by Percoll® density gradient centrifugation. Granulocyte and hyalinocyte proteins were separated by 2D-PAGE and their protein profiles were analysed and compared with PD Quest software; the protein spots exclusive for each haemocyte type were excised from gels and analysed by MALDI-TOF/TOF with a combination of mass spectrometry (MS) and MS/MS for sequencing and protein identification. A total of 34 proteins were identified, 20 unique to granulocytes and 14 to hyalinocytes. The results suggested differences between the haemocyte types in signal transduction, apoptosis, oxidation reduction processes, cytoskeleton, phagocytosis and pathogen recognition. These results contribute to identify differential roles of each haemocyte type and to better understand the oyster immunity mechanisms, which should help to fight oyster diseases.

Dual transcriptomic analysis of Ostreid herpesvirus 1 infected Scapharca broughtonii with an emphasis on viral anti-apoptosis activities and host oxidative bursts. FISH & SHELLFISH IMMUNOLOGY 2018; 82:554-564.

Abstract
The ark shell, Scapharca (Anadara) broughtonii, is an economically important marine shellfish species in Northwestern Pacific. Mass mortalities of ark shell adults related to Ostreid herpesvirus-1 (OsHV-1) infection have occurred frequently since 2012. However, due to the lack of transcriptomic resource of ark shells, the molecular mechanisms underpinning the virus-host interaction remains largely undetermined. In the present study, we resolved the dual transcriptome changes of OsHV-1 infected ark shell with Illumina sequencing. A total of 44 M sequence reads were generated, of which 67,119 reads were mapped to the OsHV-1 genome. De novo assembly of host reads resulted in 276,997 unigenes. 74,529 (26.90%), 47,653 (17.20%) and 19, 611 (7.07%) unigenes were annotated into GO, KOG and KEGG database, respectively. According to RSEM expression values, we identified 2998 differentially expressed genes (DEGs) between control and challenged groups, which included 2065 up-regulated unigenes and 933 down-regulated unigenes. Further analysis of functional pathways indicated that OsHV-1 could inhibit host cell apoptosis mainly by the up-regulation of inhibitor of apoptosis protein (IAP), and thus facilitating its successful replication. While host hemoglobins could induce oxidative burst by suppressing its peroxidase activity, and thus defense against OsHV-1 infection. Although we reported a narrow expression of the OsHV-1 genome compared to Crassostrea gigas infection, we highlighted several common viral genes highly expressed in the two hosts, suggesting an important functional role. This study offers insights into the pathogenesis mechanisms of OsHV-1 infection in bivalve mollusks of the Arcidae family.

Abstract
European flat oyster Ostrea edulis populations have suffered extensive mortalities caused by bonamiosis. The protozoan parasite Bonamia ostreae is largely responsible for this disease in Europe, while its congener B. exitiosa has been detected more recently in various European countries. Both of these intracellular parasites are able to survive and proliferate within haemocytes, the main cellular effectors of the immune system in molluscs. Two-dimensional electrophoresis was used to compare the haemolymph protein profile between Bonamia spp.-infected and non-infected oysters within 3 different stocks, a Galician stock of oysters selected for resistance against bonamiosis, a non-selected Galician stock and a selected Irish stock. Thirty-four proteins with a presumably relevant role in the oyster-Bonamia spp. interaction were identified; they were involved in major metabolic pathways, such as energy production, respiratory chain, oxidative stress, signal transduction, transcription, translation, protein degradation and cell defence. Furthermore, the haemolymph proteomic profiles of the non-infected oysters of the 2 Galician stocks were compared. As a result, 7 proteins representative of the non-infected Galician oysters selected for resistance against bonamiosis were identified; these 7 proteins could be considered as candidate markers of resistance to bonamiosis, which should be further assessed.

Abstract
Although a wide range of viruses have been reported in marine molluscs, most of these reports rely on ultrastructural examination and few of these viruses have been fully characterized. The lack of marine mollusc cell lines restricts virus isolation capacities and subsequent characterization works. Our current knowledge is mostly restricted to viruses affecting farmed species such as oysters Crassostrea gigas, abalone Haliotis diversicolor supertexta or the scallop Chlamys farreri. Molecular approaches which are needed to identify virus affiliation have been carried out for a small number of viruses, most of them belonging to the Herpesviridae and birnaviridae families. These last years, the use of New Generation Sequencing approach has allowed increasing the number of sequenced viral genomes and has improved our capacity to investigate the diversity of viruses infecting marine molluscs. This new information has in turn allowed designing more efficient diagnostic tools. Moreover, the development of experimental infection protocols has answered some questions regarding the pathogenesis of these viruses and their interactions with their hosts. Control and management of viral diseases in molluscs mostly involve active surveillance, implementation of effective bio security measures and development of breeding programs. However factors triggering pathogen development and the life cycle and status of the viruses outside their mollusc hosts still need further investigations.

Abstract
The protein expression profiling in clam haemocytes and plasma in response to Perkinsus olseni was addressed. Adult Manila clams from a P. olseni-free bed were experimentally challenged with parasite zoospores to analyse immune response. In another experiment, the effects of longer term infection were assessed in adult clams collected from a P. olseni-affected bed, by comparing moderate to very heavily infected clams with non-infected ones. Haemocyte and plasma proteins were separated by two-dimensional electrophoresis; spot patterns were qualitatively compared between treatments within each experiment and the spots indicating differential protein expression associated with P. olseni challenge or with field infection were processed for protein identification. Fifteen clam proteins (four in haemocytes and eleven in plasma) of which expression was markedly affected by P. olseni were identified. Some of the identified proteins have a well-known role in clam immune response against the parasite, such as lysozyme and lectins. Rho GTPase-activating protein 6 could be a marker of resistance against P. olseni, which should be further studied.

Abstract
The scallop Chlamys farreri is an important aquaculture species in northern China. However, the sustainable development of the scallop industry is currently threatened by several pathogens that cause mass mortality of this mollusk. Therefore, a complete understanding of the immune response mechanisms involved in host-virus interactions is necessary. This study reports a novel QM gene from C. farreri. This gene was first identified as a putative tumor suppressor gene from human and then confirmed to participate in several functions, including immune response. The QM gene from C. farreri (CfQM) was identified by suppression subtractive hybridization, and its full-length (763 bp) cDNA was obtained through rapid amplification of cDNA ends. The cDNA of CfQM contained a short 5'-UTR of 22 bp and a 3'-UTR of 84 bp. Its ORF comprised 657 nucleotides that encode 218 amino acids with a molecular weight of approximately 28.3 kDa and an isoelectric point of 10.06. The deduced amino acid sequence of CfQM contained a series of conserved functional motifs that belong to the QM family. Phylogenetic analysis revealed that CfQM was closely related to other mollusk QM proteins, and altogether they form a mollusk QM protein subfamily that displays evolutionary conservation from yeast to human. The tissue-specific expression and transcriptional regulation of CfQM were investigated by quantitative real-time PCR in response to bacterial (Vibrio anguillarum) and viral (acute viral necrobiotic virus) challenges. The transcript level of CfQM was high in all of the examined tissues in a constitutive manner. The highest and lowest expression levels of CfQM were measured in the hepatopancreas and hemocyte, respectively. Upon bacterial and viral challenges, the relative mRNA expression of CfQM sharply increased at 6 h post-infection (hpi) and then normalized at 48 hpi. These findings suggest that CfQM can respond to and protect against pathogen challenge. To the best of our knowledge, this study is the first report of the QM gene from scallop. The results presented herein provided new insights into the molecular basis of host-pathogen interactions in C. farreri.

Abstract
Skin ulceration syndrome (SUS) was the main limitation in the development of Apostichopus japonicus culture industries. To better understand how Vibrio splendidus modulates SUS outbreak, the immune response of A. japonicus coelomocytes after the pathogen challenge were investigated through comparative proteomics approach, and differentially expressed proteins were screened and characterized in the present study. A total of 40 protein spots representing 30 entries were identified at 24, 72 and 96 h post-infection. Of these proteins, 32 were up-regulated and 8 were down-regulated in the V. splendidus challenged samples compared to those of control. These differentially expressed proteins were mainly classified into four categories by GO analysis, in which approximate 33% of proteins showed to be related to immunity response. The mRNA expression levels of 6 differentially expressed proteins were further validated by qRT-PCR. Similar protein-mRNA-level expression patterns were detected in genes of phospholipase (spot 4), G protein (spot 20), annexin (spot 30) and filamin (spot 31). Whilst the levels of ficolin (spot 12) and calumenin (spot 14) transcripts were not corresponded with those of their translation products. These data provide a new insight to understand the molecular immune mechanism of sea cucumber responsive towards pathogen infection.

Abstract
The sustainable development of the scallop Chlamys farreri industry in China is hindered by mass mortality mainly caused by a novel pathogen known as acute viral necrosis virus (AVNV). A better understanding of host-virus interactions, especially those at the molecular level, may facilitate the prevention and cure of AVNV infections. MicroRNAs (miRNAs) represent a class of small RNA molecules involved in several biological processes, including mediating host-pathogen responses. In this study, two hemocyte small RNA libraries were constructed from control (control library, CL) and AVNV-infected (infection library, IL) C. farreri for high throughput sequencing using Solexa technology. Acquired data were further used to identify conserved and novel miRNAs, screen differentially expressed miRNAs, and predict their target genes through bioinformatics analysis. Solexa sequencing produced 19,485,719 and 20,594,513 clean reads representing 2,248,814 and 1,510,256 unique small RNAs from CL and IL, respectively. A total of 57 conserved miRNAs were identified in both libraries, among which only two were unique to IL. Novel miRNA prediction using the Crassostrea gigas genome as a reference revealed 11 candidate miRNAs, 10 of which were validated by RT-PCR. Differential expression (p < 0.001) between libraries was observed in 37 miRNAs, among which 30 and 7 miRNAs were up- and downregulated, respectively. Expression differences were further confirmed by qRT-PCR. A sequence homology search against available C. farreri ESTs showed that these differentially expressed miRNAs may target 177 genes involved in a broad range of biological processes including immune defense and stress response. This study is the first to characterize C. farreri miRNAs and miRNA expression profiles in response to AVNV infection by deep sequencing. The results presented here will deepen our understanding of the pathogenesis of AVNV at the molecular level and provide new insights into the molecular basis of host-pathogen interactions in C. farreri.

FISH & SHELLFISH IMMUNOLOGY 2014; 36:252-260. [PMID: 24262301 DOI: 10.1016/j.fsi.2013.11.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2013] [Revised: 11/04/2013] [Accepted: 11/10/2013] [Indexed: 06/02/2023]
Abstract
Heat stress and pathogen infection have been considered as the main causes for mass mortality of cultured scallops during summer. In the present study, the expression profiles of proteins in the hepatopancreas of scallop Chlamys farreri were examined to reveal the possible mechanisms of physiological responses of scallop beneath heat stress and bacterial infection. An earlier occurred and higher mortality was observed in the scallops from combination treated group (28 °C and an injection of Vibrio anguillarum) in comparison to those in heat stress (28 °C) and bacteria challenge (V. anguillarum injection only) group, as well as control (PBS) and blank (untreated) group. The proteins in the hepatopancreas from scallops post 6 h of treatment were analyzed by using 2-D PAGE and ImageMaster 2D Platinum. There were total 1003 spots detected in control group, 1193 spots in heat stress group, 1263 spots in bacteria challenge group, and 1241 spots in the combination group. Fifteen protein spots expressed differentially between the combination treatment group and the bacteria challenge group were successfully identified by mass spectrometry and they were mainly classified as binding and catalytic proteins, such as endoglucanase, methylmalonate-semialdehyde dehydrogenase, xylose isomerase, tryptophanyl-tRNA synthetase, 40s ribosomal protein SA, glutathione S-transferase 4, and Mitochondrial transcription factor A, etc. These results indicated that the mortality of scallops suffered from the combination treatment was probably attributed to the impaired modulation of digestion and metabolism and ruined protein synthesis caused by heat stress together with bacteria infection. These data also provided valuable insights into the possible mechanisms of summer mortality occurrence of scallop at protein level.

Abstract
Selenium binding proteins (SeBPs) play a crucial role in controlling the oxidation/reduction in many physiological processes. Here we reported the isolation and characterization of a cDNA of SeBP gene from Sinonovacula constricta (denoted as ScSeBP). The full-length cDNA of ScSeBP was of 2345 bp, consisting of a 5'UTR of 246 bp, a 3' UTR of 626 bp, and a complete ORF of 1473 bp encoding a polypeptide with 491 amino acid residues. The predicted molecular mass of deduced amino acid of ScSeBP was 54.85 kDa and the theoretical pI was 6.44. Tissue distribution analysis of the ScSeBP revealed that the mRNA transcripts of ScSeBP were constitutively expressed in all examined tissues with the higher expressions in gill, gonad and the haemocytes. The temporal expression of ScSeBP in gill and haemocytes after B[α]P and heavy metals exposure were recorded by qPCR. B[α]P exposure at 0.5 and 5 mg L(-1) caused significant increase in mRNA expression of ScSeBP in haemocytes, but down-regulated ScSeBP mRNA expression in gill. Concerning heavy metals stresses, the suppressed expression patterns were detected in gill and haemocyte except lower concentration of PbCl2 exposure in haemocytes at 12 h. All our results indicated that ScSeBP was one of key effectors in mediating B[α]P and heavy metals exposure.

FISH & SHELLFISH IMMUNOLOGY 2013; 34:1619-1627.

Abstract
The scallop Chlamys farreri is one of the most important aquaculture species in northern coastal provinces. However, the sustainable development of scallop industry is currently threatened by a notorious pathogen named as acute viral necrobiotic virus (AVNV), which often causes mass mortality of the animals. Despite that great attention has been focused on this novel pathogen, little knowledge about the host-virus interactions is available. In this study, suppression subtractive hybridization (SSH) was employed to identify the up-regulated differentially expressed genes in the hemocytes of C. farreri challenged by AVNV. A forward subtracted cDNA library was finally constructed and 288 positive colonies representing differentially genes were screened to perform sequencing. A total of 275 ESTs were used for further analysis using bioinformatics tools after vector screening, among which 167 ESTs could be finally identified, with significant match (E values <1 × 10(-3)) to the deposited genes (proteins) in the corresponding databases. These genes could be classified into ten categories according to their Gene Ontology annotations of biological processes and molecular functions, i.e. cell defense and homeostasis (13.82%), cellular protein metabolic process (14.90), cellular metabolism (13.09%), cytoskeletal or cellular component (5.82%), transcription regulation or RNA processing (2.18%), cell division (meiosis)/apoptosis (2.18%), DNA metabolic process and repair (1.45%), cell adhesion/signaling (1.09%), microsatellite (0.73%), and ungrouped or unknown functions (6.88). The possible biological significance of some novel genes (mainly immune and homeostasis related genes) in the host response to AVNV were discussed. This study is the first global analysis of differentially expressed genes in hemocytes from AVNV-infected C. farreri, and in addition to increasing our understanding of the molecular pathogenesis of this virus-associated scallop disease, the results presented here should provide new insights into the molecular basis of host-pathogen interactions in C. farreri.

Abstract
In this study, we present a comparative proteomic analysis of the global protein expression changes in sea cucumber after 7 days exposure at 25°C. Using two-dimensional electrophoresis followed by MALDI-TOF MS/MS, 27 protein spots with significant differences in abundance were identified and characterized. The identified proteins belonged primarily to the following four functional categories: cytoskeletal, material and energy metabolism, calcium homeostasis and extracellular matrix. The mRNA expression levels of 7 differentially expressed proteins were further assessed by qRT-PCR. The expression levels of 6 genes, including collagen, ATP synthase, major yolk protein, ferritin, nectin and protein disulfide isomerase showed significant differences under thermal stress, and among them, only two genes-ATP synthase and major yolk protein-showed consistent levels of protein and mRNA expression. Our results offer insight into the complex changes in protein turnover during higher temperature exposure in sea cucumber.

Abstract
Human pharmaceuticals (e.g. the lipid regulator gemfibrozil and the non-steroidal anti-inflammatory drug diclofenac) are an emerging environmental threat in the aquatic environment. This study aimed to evaluate sublethal effects of these two commonly found pharmaceuticals on the protein profiles of marine mussels (Mytilus spp.). Mytilus spp. was exposed to environmentally relevant and elevated concentrations (1 and 1000 µg/l respectively) of both drugs for 14 days. In addition, mussels were maintained for seven days post treatment to examine the potential of blue mussels to recover from such an exposure. Differential protein expression signatures (PES) in the digestive gland of mussels were obtained using two-dimensional gel electrophoresis after 7, 14, and 21 days of exposure. Twelve spots were significantly increased or decreased by gemfibrozil and/or diclofenac, seven of which were successfully identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. These proteins were involved in energy metabolism, oxidative stress response, protein folding, and immune responses. Changes in the PES over time suggested that mussels were still experiencing oxidative stress for up to seven days post exposure. In addition, a suite of biomarkers comprising glutathione transferase, lipid peroxidation, and DNA damage were studied. An oxidative stress response was confirmed by biomarker responses. To our knowledge, this is the first investigation using proteomics to assess the potential effects of human pharmaceuticals on a non-target species in an environmentally-relevant model. The successful application of this proteomic approach supports its potential use in pollution biomonitoring and highlights its ability to aid in the discovery of new biomarkers.

Abstract
China is the largest fishery producer worldwide in term of its aquaculture output, and plays leading and decisive roles in international aquaculture development. To improve aquaculture output further and promote aquaculture business development, infectious diseases and immunity of fishes and other aquaculture species must be studied. In this regard, aquaculture proteomics has been widely carried out in China to get a better understanding of aquaculture host immunity and microbial pathogenesis as well as host-pathogen interactions, and to identify novel disease targets and vaccine candidates for therapeutic interventions. These proteomics studies include development of novel methods, assays, and advanced concepts in order to characterize proteomics mechanisms of host innate immune defense and microbial pathogenesis. This review article summarizes some recently published technical approaches and their applications to aquaculture proteomics with an emphasis on the responses of aquaculture animals to bacteria, viruses, and other aqua-environmental stresses, and development of broadly cross-protective vaccine candidates. The reviewed articles are those that have been published in international peer reviewed journals.

Abstract
Over the last forty years global aquaculture presented a growth rate of 6.9% per annum with an amazing production of 52.5 million tonnes in 2008, and a contribution of 43% of aquatic animal food for human consumption. In order to meet the world's health requirements of fish protein, a continuous growth in production is still expected for decades to come. Aquaculture is, though, a very competitive market, and a global awareness regarding the use of scientific knowledge and emerging technologies to obtain a better farmed organism through a sustainable production has enhanced the importance of proteomics in seafood biology research. Proteomics, as a powerful comparative tool, has therefore been increasingly used over the last decade to address different questions in aquaculture, regarding welfare, nutrition, health, quality, and safety. In this paper we will give an overview of these biological questions and the role of proteomics in their investigation, outlining the advantages, disadvantages and future challenges. A brief description of the proteomics technical approaches will be presented. Special focus will be on the latest trends related to the aquaculture production of fish with defined nutritional, health or quality properties for functional foods and the integration of proteomics techniques in addressing this challenging issue.
