Abstract
Thrombospondins (TSPs) are multidomain, calcium-binding glycoproteins that have wide-ranging roles in vertebrates in cell interactions, extracellular matrix (ECM) organisation, angiogenesis, tissue remodelling, synaptogenesis, and also in musculoskeletal and cardiovascular functions. Land animals encode five TSPs, which assembly co-translationally either as trimers (subgroup A) or pentamers (subgroup B). The vast majority of research has focused on this canonical TSP family, which evolved through the whole-genome duplications that took place early in the vertebrate lineage. With benefit of the growth in genome- and transcriptome-predicted proteomes of a much wider range of animal species, examination of TSPs throughout metazoan phyla has revealed extensive conservation of subgroup B-type TSPs in invertebrates. In addition, these searches established that canonical TSPs are, in fact, one branch within a TSP superfamily that includes other clades designated mega-TSPs, sushi-TSPs and poriferan-TSPs. Despite the apparent simplicity of poriferans and cnidarians as organisms, these phyla encode a greater diversity of TSP superfamily members than vertebrates. We discuss here the molecular characteristics of the TSP superfamily members, current knowledge of their expression profiles and functions in invertebrates, and models for the evolution of this complex ECM superfamily.

Abstract
Cathepsins belong to a group of proteins that are present in both prokaryotic and eukaryotic organisms and have an extremely high degree of evolutionary conservation. These proteins are functionally active in extracellular environments as soluble enzymatic proteins or attached to plasma membrane receptors. In addition, they occur in cellular secretory vesicles, mitochondria, the cytosol, and within the nuclei of eukaryotic cells. Cathepsins are classified into various groups based on their sequence variations, leading to their structural and functional diversification. The molecular understanding of the physiology of crustaceans has shown that proteases, including cathepsins, are expressed ubiquitously. They also contain one of the central regulatory systems for crustacean reproduction, growth, and immune responses. This review focuses on various aspects of the crustaceans cathepsins and emphasizes their biological roles in different physiological processes such as reproduction, growth, development, and immune responses. We also describe the bioactivity of crustaceans cathepsins. Because of the vital biological roles that cathepsins play as cellular proteases in physiological processes, they have been proposed as potential novel targets for the development of management strategies for the aquaculture industries.

Shrimp thrombospondin (TSP): presence of O-β1,4 N-acetylglucosamine polymers and its function in TSP chain association in egg extracellular matrix. Sci Rep 2022; 12:7925. [PMID: 35562392 PMCID: PMC9106747 DOI: 10.1038/s41598-022-11873-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 04/29/2022] [Indexed: 11/12/2022] Open
Abstract
We characterized the existence of O-β(1,4)-GlcNAc polymers (β1,4GNP) that were anchored on the O-linked glycosylation sites of shrimp thrombospondin (pmTSP-II). There were five putative β1,4GNP linkages on the epithelial growth factor-like domain of pmTSP-II. Antibody against O-β-GlcNAc (CTD110.6) was used to prove the existence of linear and complex β1,4GNP. The antibody well reacted with linear chito-triose, -tetraose and -pentaose conjugated with phosphatidylethanolamine lipid. The immunoreactivity could also be detected with a complex β1,4GNP within pmTSP-II (at MW > 250 kDa). Upon denaturing the protein with SDS-PAGE buffer, the size of pmTSP-II was shifted to be 250 kDa, approximately 2.5 folds larger than the deduced molecular mass of pmTSP-II (110 kDa), suggesting additional association of pmTSP-II apart from its known disulfide bridging. This was confirmed by chitinase digestion on pmTSP-II protein leading to the subsequent smaller protein bands at 110–170 kDa in time- and concentration-dependent manners. These bands well reacted with CTD110.6 antibody and disappeared after extensive chitinase hydrolysis. Together, we believe that β1,4GNP on pmTSP-II serve the function in an inter-chain association to provide structural architecture of egg extracellular matrix, a novel function of pmTSP-II in reproductive biology.

Abstract
Thrombospondin (TSP) gene expression in response to WSSV infection in shrimp, Penaeus monodon. Expression pattern of TSP gene in the presence and absence of β-glucan fed shrimp. High-level expression of TSP gene in various tissues of WSSV-challenged shrimp at 2 h. Altered gene expression pattern in WSSV-challenged shrimp, fed with and without β-glucan. TSP could play a role as an acute inducible phase response protein to WSSV infection.
Thrombospondins (TSPs) are extracellular, calcium-binding glycoproteins that play an essential role in cell homeostasis and development, wound-healing, angiogenesis, connective tissue organization, immune response etc. and it conserves from sea sponges to mammals. However, their role in shrimp immunity is poorly understood. In the present study, the differential expression profiling of TSP transcripts in Penaeus monodon tissues such as gills, lymphoid organs, hepatopancreas, and hemolymph challenged with white spot syndrome virus (WSSV), were studied by quantitative real-time PCR. Further, shrimps fed with the immunostimulant (β-glucan) when challenged with WSSV showed significant upregulation of TSP expression in gills, hepatopancreas, and lymphoid organ at the early phase of WSSV infection. The results suggest that TSP may be an inducible acute phase response protein to WSSV infection. The possibility of differences in mRNA expression pattern seen in immunostimmulated shrimp after the viral challenge, possibility due to altered immune mechanisms getting triggered during immunostimulant administration and virus infections in the host.

Abstract
JAK/STAT signaling pathway is suggested to enhance the infection of WSSV in crustaceans. However, the regulation mechanism of this process is not quite clear. Here, comparative transcriptomic analysis was performed among shrimps before and after Litopenaeus vannamei STAT (LvSTAT) was silenced by dsRNA approach during WSSV infection. Differentially expressed genes (DEGs) common in the STAT-interfered groups and control groups at different times after WSSV infection were analyzed to acquire the genes probably regulated by LvSTAT. DEGs annotation and further GO terms enrichment analyses revealed that the identified DEGs mainly contained two categories, chitin-binding domain containing proteins and energy metabolism related genes. The former mainly included cuticle proteins, thrombospondins (TSPs) and peritrophin, while the later mainly included hexose catabolic process and glycolysis related genes. Two cuticle proteins and two TSPs were further studied to learn their expression changes during WSSV infection. They were significantly regulated during WSSV infection, implying the involvement of chitin-binding domain containing protein in the invasion process of WSSV. Systematic analysis on the glycolysis and lipid synthesis pathway demonstrated that silencing of LvSTAT could reduce the glycolysis efficiency and the production of lipids. It could be speculated that a favorable function of LvSTAT for WSSV replication existed by regulating the energy metabolism of the host. Through revealing the main category of genes and biological processes regulated by STAT, our study could shed new light on the roles of JAK/STAT signaling pathway in shrimp during virus infection.

Abstract
Vitellogenesis is a principal process during ovarian maturation in crustaceans. This process is negatively regulated by gonad-inhibiting hormone (GIH), a neuronal peptide hormone from eyestalks. However, the detailed mechanism through which GIH regulates Vg expression is still ambiguous. In this study, suppression subtractive hybridization (SSH) under specific GIH-knockdown condition was utilized to determine the expression of genes in the ovary that may act downstream of GIH to control vitellogenin synthesis in Penaeus monodon. The total of 102 and 82 positive clones of up-regulated and down-regulated genes in GIH- knockdown shrimp were identified from the forward and reverse SSH libraries, respectively. Determination of the expression profiles of these reproduction-related genes during ovarian development revealed that the expression of calreticulin (CALR) was significantly reduced in vitellogenic ovary suggesting its role in vitellogenesis. Suppression of CALR by specific dsRNA showed elevated vitellogenin (Vg) transcript level in the ovary at day 7 post-dsRNA injection. Since CALR can bind to steroid hormone receptors and prevents the binding of the receptor to its responsive element to regulate gene expression, it is possible that CALR is an inhibitory mediator of vitellogenin synthesis via steroidal pathway. Our results posted a possible novel pathway of GIH signaling that might interfere the steroid signaling cascade to mediate Vg synthesis in the shrimp.

Abstract
Crustacean reproduction has been hypothesized to be under complex endocrinological regulation by peptide hormones. To further improve our understanding of the mechanisms underlying this complex regulation, knowledge is needed regarding the hormones not only of the central nervous system (CNS) such as the X-organ/sinus gland (XOSG), brain, and thoracic ganglia, but also the peripheral gonadal tissues. For example, in vertebrates, some gonadal peptide hormones including activin, inhibin, follistatin, and relaxin are known to be involved in the reproductive physiology. Therefore, it is highly likely that some peptide factors from the ovary are serving as the signals among peripheral tissues and central nervous tissues in crustaceans. In this work, we sought to find gonadal peptide hormones and peptide hormone receptors by analyzing the transcriptome of the ovary of the kuruma prawn Marsupenaeus japonicus. The generated ovarian transcriptome data led to the identification of five possible peptide hormones, including bursicon-α and -β, the crustacean hyperglycemic hormone (CHH)-like peptide, insulin-like peptide (ILP), and neuroparsin-like peptide (NPLP). Dominant gene expressions for the bursicons were observed in the thoracic ganglia and the ovary, in the CNS for the CHH-like peptide, in the heart for NPLP, and in the ovary for ILP. Since the gene expressions of CHH-like peptide and NPLP were affected by a CHH (Penaeus japonicus sinus gland peptide-I) from XOSG, we produced recombinant peptides for CHH-like peptide and NPLP using Escherichia coli expression system to examine their possible peripheral regulation. As a result, we found that the recombinant NPLP increased vitellogenin gene expression in incubated ovarian tissue fragments. Moreover, contigs encoding putative receptors for insulin-like androgenic gland factor, insulin, neuroparsin, and neuropeptide Y/F, as well as several contigs encoding orphan G-protein coupled receptors and receptor-type guanylyl cyclases were also identified in the ovarian transcriptome. These results suggest that reproductive physiology in crustaceans is regulated by various gonadal peptide hormones, akin to vertebrates.

Abstract
Glycoconjugates in egg extracellular matrices are known to serve several functions in reproductive processes. Here, the presence of N-linked mannose (Man) glycoconjugates on shrimp thrombospondin ( pmTSP-II) and their physiological functions were investigated in the black tiger shrimp Penaeus monodon. A molecular analysis of pmTSP-II demonstrated anchorage sites for N-linked glycans in both the chitin-binding and TSP3 domains. The presence of Man residues was verified by concanavalin A lectin histochemistry on the purified fraction of pmTSP-II (250 kDa with protease inhibitor). The function of the Man glycoconjugates was evident by the Con A interference with the pmTSP-II-induced acrosome reaction (AR) as well as by the ability to recover the induction of the AR by the inclusion of Mans in the treatment mixture. In addition, the recombinant proteins of the three signature pmTSP-II domains expressed in E. coli (lacking glycosylation) and mannosidase-treated pmTSP-II showed a minimal ability to initiate the AR response. Together, these results provide evidence of the pivotal role that Man-linked pmTSP-II plays in modulating the shrimp sperm AR, a novel role for a TSP family protein in shrimp reproductive biology.

Abstract
Vitellogenesis is the process of yolk formation via accumulating vitellin (Vn) with nutrients in the oocytes. Expression of vitellogenin (Vg), the precursor of Vn, is one of the indicators for the start of vitellogenesis. In Pacific white shrimp (Litopenaeus vannamei), the type-II vitellogenesis-inhibiting hormone (VIH-2) effectively suppresses hepatopancreatic Vg mRNA expression. In this study, we demonstrate the increasing transcript levels of hepatopancreatic Vg during L. vannamei ovarian development, suggesting that the hepatopancreas-derived Vg/Vn may also contribute to vitellogenesis in this species. Using a combination of in vivo injections and in vitro primary cell cultures, we provide evidences that the inhibition of VIH-2 on hepatopancreatic Vg gene expression is mediated through a functional coupling of the GC/cGMP pathway with different MAPK-dependent cascades in female shrimp. In VIH-2 signaling, the NO-independent GC/cGMP/PKG cascades were upstream of the MAPKs. Activations of the MAPK signal by VIH-2 include the phosphorylation of JNK and the mRNA/protein expression of P38MAPK. Additionally, the cAMP/PKA pathway is another positive intracellular signal for hepatopancreatic Vg mRNA expression but is independent of its VIH-2 regulation. Our findings establish a model for the signal transduction mechanism of Vg regulation by VIH and shed light on the biological functions and signaling of the CHH family in crustaceans.

Abstract
The extracellular matrix (ECM) has central roles in tissue integrity and remodeling throughout the life span of animals. While collagens are the most abundant structural components of ECM in most tissues, tissue-specific molecular complexity is contributed by ECM glycoproteins. The matricellular glycoproteins are categorized primarily according to functional criteria and represented predominantly by the thrombospondin, tenascin, SPARC/osteonectin, and CCN families. These proteins do not self-assemble into ECM fibrils; nevertheless, they shape ECM properties through interactions with structural ECM proteins, growth factors, and cells. Matricellular proteins also promote cell migration or morphological changes through adhesion-modulating or counter-adhesive actions on cell-ECM adhesions, intracellular signaling, and the actin cytoskeleton. Typically, matricellular proteins are most highly expressed during embryonic development. In adult tissues, expression is more limited unless activated by cues for dynamic tissue remodeling and cell motility, such as occur during inflammatory response and wound repair. Many insights in the complex roles of matricellular proteins have been obtained from studies of gene knockout mice. However, with the exception of chordate-specific tenascins, these are highly conserved proteins that are encoded in many animal phyla. This review will consider the increasing body of research on matricellular proteins in nonmammalian animal models. These models provide better access to the very earliest stages of embryonic development and opportunities to study biological processes such as limb and organ regeneration. In aggregate, this research is expanding concepts of the functions and mechanisms of action of matricellular proteins.

Molt-inhibiting hormone (MIH), a peptide member of the crustacean hyperglycemic hormone (CHH) family, is commonly considered as a negative regulator during the molt cycle in crustaceans. Phylogenetic analysis of CHH family peptides in penaeidae shrimps suggested that there is no significant differentiation between MIH and vitellogenesis-inhibiting hormone (VIH, another peptide member of CHH family), by far the most potent negative regulator of crustacean vitellogenesis known. Thus, MIH may also play a role in regulating vitellogenesis. In this study, two previously reported putative MIHs (LivMIH1 and LivMIH2) in the Pacific white shrimp (Litopenaeus vannamei) were expressed in Escherichia coli, purified by immobilized metal ion affinity chromatography (IMAC) and further confirmed by western blot. Regulation of vitellogenin (VTG) mRNA expression by recombinant LivMIH1 and LivMIH2 challenge was performed by both in vitro hepatopancreatic primary cells culture and in vivo injection approaches. In in vitro primary culture of shrimp hepatopancreatic cells, only LivMIH2 but not LivMIH1 administration could improve the mRNA expression of VTG. In in vivo injection experiments, similarly, only LivMIH2 but not LivMIH1 could stimulate hepatopancreatic VTG gene expression and induce ovary maturation. Our study may provide evidence for one isoform of MIH (MIH2 in L. vannamei) may serve as one of the mediators of the physiological progress of molting and vitellogenesis. Our study may also give new insight in CHH family peptides regulating reproduction in crustaceans, in particular penaeidae shrimps.

Abstract
Ovarian maturation in crustaceans is temporally orchestrated by two processes: oogenesis and vitellogenesis. The peptide hormone vitellogenesis-inhibiting hormone (VIH), by far the most potent negative regulator of crustacean reproduction known, critically modulates crustacean ovarian maturation by suppressing vitellogenin (VTG) synthesis. In this study, cDNA encoding VIH was cloned from the eyestalk of Pacific white shrimp, Litopenaeus vannamei, a highly significant commercial culture species. Phylogenetic analysis suggests that L. vannamei VIH (lvVIH) can be classified as a member of the type II crustacean hyperglycemic hormone family. Northern blot and RT-PCR results reveal that both the brain and eyestalk were the major sources for lvVIH mRNA expression. In in vitro experiments on primary culture of shrimp hepatopancreatic cells, it was confirmed that some endogenous inhibitory factors existed in L. vannamei hemolymph, brain, and eyestalk that suppressed hepatopancreatic VTG gene expression. Purified recombinant lvVIH protein was effective in inhibiting VTG mRNA expression in both in vitro primary hepatopancreatic cell culture and in vivo injection experiments. Injection of recombinant VIH could also reverse ovarian growth induced by eyestalk ablation. Furthermore, unilateral eyestalk ablation reduced the mRNA level of lvVIH in the brain but not in the remaining contralateral eyestalk. Our study, as a whole, provides new insights on VIH regulation of shrimp reproduction: 1) the brain and eyestalk are both important sites of VIH expression and therefore possible coregulators of hepatopancreatic VTG mRNA expression and 2) eyestalk ablation could increase hepatopancreatic VTG expression by transcriptionally abolishing eyestalk-derived VIH and diminishing brain-derived VIH.

Abstract
The meiotic maturation of oocytes is regulated by the maturation-promoting factor (MPF), a complex of Cdc2 (Cdk1) and Cyclin B. Here, the complete open reading frame (ORF) of Cdc2 in Penaeus monodon was characterized. PmCdc2 were 900bp in length corresponding to a polypeptide of 299 amino acids with the conserved Thr14, Tyr15 and Thr161 residues. Quantitative real-time PCR indicated that the expression level of PmCdc2 in wild intact broodstock was significantly increased in stages II (vitellogenic) and III (early cortical rod) ovaries relative to stage I (previtellogenic) ovaries and peaked in stage IV (mature) ovaries (P<0.05). The expression level of PmCdc2 in stages I-IV ovaries of eyestalk-ablated broodstock was greater than that of the same ovarian developmental stages in intact broodstock (P<0.05). Expression levels of PmCdc2 in ovaries of 18-month-old P. monodon upon 5-HT injection (50μg/g body weight) were significantly increased at 1hour post injection (hpi, P<0.05). Recombinant PmCdc2 protein and its polyclonal antibody were successfully produced. Western blot analysis revealed the expected 34kDa band (PmCdc2) along with a smaller band of 23kDa (ribosomal protein S3) in ovaries of juveniles and various ovarian stages of broodstock. Using phospho-Cdc2 (Thr161) polyclonal antibody, the positive signal of 34kDa was observed in all ovarian stages but the most intense signal was found in stage IV ovaries. Results in the present study indicated that PmCdc2 gene/protein plays an important role in the development and maturation of oocytes/ovaries in P. monodon.

Abstract
We have recently shown that water-soluble materials from the egg extracellular cortical rods (wsCRs) exert the ability to induce the sperm acrosome reaction in Penaeus monodon. In this study, we further demonstrated that the thrombospondin protein family (TSP) existed in wsCRs, and that their mRNA transcripts were detected in developing oocytes as early as stage I. Full sequence analysis revealed that our pmTSP sequence was considerably different from the recently reported pmTSP in the 5' nonconserved region and in many TSP signature domains, hence, the name pmTSP-II was given to our variant. The transcripts of pmTSP-II were detected only in early developing oocytes (stage-I and -II) while TSP-like proteins were detected in all developing oocytes, particularly at the outer rim of cortical rods situated in the extracellular crypts of the mature, stage-IV oocytes. In addition, wsCRs contained anti-TSP-reactive proteins, suggesting that TSP-like proteins are dissolved in and are part of the egg water during spawning. The functional importance of TSP-like proteins was evident by the interference of a wsCR-induced acrosome reaction response with anti-TSP in a concentration-dependent manner. In summary, we found that pmTSP-II transcripts were present in the developing oocytes and pmTSP-II protein accumulated in cortical rods, which are partly secreted and thus solubilized to produce dissolved TSP-like proteins that participate in induction of the sperm acrosome reaction-a novel reproductive role for TSP protein family.

Abstract
It is widely accepted that protein phosphorylation is a major control event in regulating cell cycle. In the present study, a novel M-phase phosphoprotein 6 (MPP6) was identified from black tiger shrimp Penaeus monodon (designated as PmMPP6) by cDNA library and RACE approaches. The full-length cDNA of PmMPP6 was of 690 bp, including a 5'-terminal un-translated region (5'UTR) of 68 bp, a 3'UTR of 172 bp with a poly (A) tail, and an open reading frame (ORF) of 450 bp encoding a polypeptide of 149 amino acids with a predicted molecular weight of 17.01 kDa. Blastx and phylogenetic analysis together supported that PmMPP6 was a novel member of shrimp MPP6. The mRNA expression of PmMPP6 in thirteen tissues was examined by real-time PCR, and mRNA transcript of PmMPP6 was predominantly detectable in tissues of lymphoid and muscle, to a lesser degree in the tissues of gill, ovary and hepatopancreas, and mainly detected in haemocytes, heart and gonad. The temporal expression of PmMPP6 in different developmental stages of ovary was investigated by real-time PCR. During the six stages of ovary development, two peaks expression of PmMPP6 was detected in stage II with 3.78-fold increase and stage V with 3.48-fold increase compared to that in stage I. All these results indicated that PmMPP6 might be involved in regulating shrimp cell cycle and ovary development.

Abstract
The reproductive features of the giant red shrimp, Aristaeomorpha foliacea, were investigated in the southern Tyrrhenian sea by experimental trawl sampling. The annual length-frequency distribution showed a multimodal trend in females, ranging between 16 and 67 mm carapace length (CL), and a unimodal trend in males (18–45 mm CL). Mature males occurred in different proportions all year round, while females displayed seasonal maturity (June—September), with a peak in July. Six oocyte developmental stages were identified, the most advanced of which (Pv, postvitellogenic) had never been described before in this species. Ovary development followed a group-synchronous pattern, with the yolked oocyte stock clearly separated from the reservoir of unyolked oocytes, suggesting that A. foliacea is a total spawner, with determinate fecundity. Based upon histological findings, a revision of macroscopic maturity staging employed in Mediterranean bottom trawl surveys (MEDITS) is proposed.

Abstract
The thrombospondins are a family of secreted, oligomeric glycoproteins that interact with cell surfaces, multiple components of the extracellular matrix, growth factors and proteases. These interactions underlie complex roles in cell interactions and tissue homeostasis in animals. Thrombospondins have been grouped functionally with SPARCs, tenascins and CCN proteins as adhesion-modulating or matricellular components of the extracellular milieu. Although all these multi-domain proteins share various commonalities of domains, the grouping is not based on structural homologies. Instead, the terms emphasise the general observations that these proteins do not form large-scale ECM structures, yet act at cell surfaces and function in coordination with the structural ECM and associated extracellular proteins. The designation of adhesion-modulation thus depends on observed tissue and cell culture ECM distributions and on experimentally identified functional properties. To date, the evolutionary relationships of these proteins have not been critically compared: yet, knowledge of their evolutionary histories is clearly relevant to any consideration of functional similarities. In this article, we survey briefly the structural and functional knowledge of these protein families, consider the evolution of each family, and outline a perspective on their functional roles.

Abstract
Thrombospondins are evolutionarily conserved, calcium-binding glycoproteins that undergo transient or longer-term interactions with other extracellular matrix components. They share properties with other matrix molecules, cytokines, adaptor proteins, and chaperones, modulate the organization of collagen fibrils, and bind and localize an array of growth factors or proteases. At cell surfaces, interactions with an array of receptors activate cell-dependent signaling and phenotypic outcomes. Through these dynamic, pleiotropic, and context-dependent pathways, mammalian thrombospondins contribute to wound healing and angiogenesis, vessel wall biology, connective tissue organization, and synaptogenesis. We overview the domain organization and structure of thrombospondins, key features of their evolution, and their cell biology. We discuss their roles in vivo, associations with human disease, and ongoing translational applications. In many respects, we are only beginning to appreciate the important roles of these proteins in physiology and pathology.

Abstract
Eyestalk ablation is commonly practiced in crustacean to induce ovarian maturation in captivity. The molecular mechanism of the ablation has not been well understood, preventing a search for alternative measures to induce ovarian maturation in aquaculture. This is the first study to employ cDNA microarray to examine effects of eyestalk ablation at the transcriptomic level and pathway mapping analysis to identify potentially affected biological pathways in the black tiger shrimp (Penaeus monodon). Microarray analysis comparing between gene expression levels of ovaries from eyestalk-intact and eyestalk-ablated brooders revealed 682 differentially expressed transcripts. Based on Hierarchical clustering of gene expression patterns, Gene Ontology annotation, and relevant functions of these differentially expressed genes, several gene groups were further examined by pathway mapping analysis. Reverse-transcriptase quantitative PCR analysis for some representative transcripts confirmed microarray data. Known reproductive genes involved in vitellogenesis were dramatically increased during the ablation. Besides these transcripts expected to be induced by the ablation, transcripts whose functions involved in electron transfer mechanism, immune responses and calcium signal transduction were significantly altered following the ablation. Pathway mapping analysis revealed that the activation of gonadotropin-releasing hormone signaling, calcium signaling, and progesterone-mediated oocyte maturation pathways were putatively crucial to ovarian maturation induced by the ablation. These findings shed light on several possible molecular mechanisms of the eyestalk ablation effect and allow more focused investigation for an ultimate goal of finding alternative methods to replace the undesirable practice of the eyestalk ablation in the future.

Abstract
In the present study, a ras-like nuclear (Ran) gene was obtained from the ovary and neurosecretory organ in eyestalk cDNA library of black tiger prawn (Penaeus monodon). The full-length black tiger prawn Ran (PmRan) cDNA consisted of 1140 nucleotides including an open reading frame (ORF) 648 bp, a 5' untranslated region (5'UTR) of 117 bp and a 3'UTR of 375 bp with a polyadenylation signal sequence "aataaa" and a poly (A) tail. The ORF encoded a peptide of 215 amino acids with molecular mass 24.6 kDa and a theoretical isoelectric point of 7.39. ScanProsite analysis indicated that PmRan protein sequence contained a small GTPase Ran family motif. Homology analysis of the deduced amino acid sequence of the PmRan with other known Ran sequences by MatGAT software revealed that the PmRan show very high homology with the sequences of other animals (92.1-98.6% similarity, 85.6-98.1% identity). Analysis of the tissue expression pattern of the PmRan gene showed that the PmRan mRNA was expressed in all tested tissues, including hepatopancreas, ovary, muscle, intestine, neurosecretory organ in eyestalk, neurosecretory organ in brain, stomach, and heart, with the highest levels in ovary. Furthermore, the PmRan expression was found to be high level in the six ovarian stages of development. The results indicated PmRan might play an important role in ovarian development.

Abstract
Expressed sequence tags (ESTs) were identified from reciprocal suppression subtractive hybridization cDNA libraries from Marsupenaeus japonicus (Kuruma shrimp) female and male gonads. The expression profiles of 24 of these ESTs were determined in female and male gonads and developing postlarvae by real-time quantitative reverse transcription-polymerase chain reaction. When expression was determined in gonads, six of the ESTs were expressed in ovaries only, and five of the ESTs were expressed in testes only. When expression was determined in whole individuals during postlarval development, expression of the ESTs was low and inconsistent until stage PL110 (110 days since metamorphosis from mysis stage to the first postlarval stage). At PL110, seven of the ESTs were detected in females only, and seven ESTs were detected in males only. Sex-specific expression at this developmental stage indicates that these ESTs act as important gonadal development markers and may have a role in gametogenesis.

Abstract
The extracellular matrix (ECM) is a complex, multiprotein network that has essential roles in tissue integrity and intercellular signaling in the metazoa. Thrombospondins (TSPs) are extracellular, calcium-binding glycoproteins that have biologically important roles in mammals in angiogenesis, vascular biology, connective tissues, immune response, and synaptogenesis. The evolution of these complex functional properties is poorly understood. We report here on the evolution of TSPs and their ligand-binding capacities, from comparative genomics of species representing the major phyla of metazoa and experimental analyses of the oligomerization properties of noncanonical TSPs of basal deuterostomes. Monomeric, dimeric, trimeric, and pentameric TSPs have arisen through separate evolutionary events involving gain, loss, or modification of a coiled-coil domain or distinct domains at the amino-terminus. The relative transience of monomeric forms under evolution implicates a biological importance for multivalency of the C-terminal region of TSPs. Most protostomes have a single TSP gene encoding a pentameric TSP. The pentameric form is also present in deuterostomes, and gene duplications at the origin of deuterostomes and gene loss and further gene duplication events in the vertebrate lineage gave rise to distinct forms and novel domain architectures. Parallel analysis of the major ligands of mammalian TSPs revealed that many binding activities are neofunctions representing either coevolutionary innovations in the deuterostome lineage or neofunctions of ancient molecules such as CD36. Contrasting widely conserved capacities include binding to heparan glycosaminoglycans, fibrillar collagen, or RGD-dependent integrins. These findings identify TSPs as fundamental components of the extracellular interaction systems of metazoa and thus impact understanding of the evolution of ECM networks. The widely conserved activities of TSPs in binding to ECM components or PS2 clade integrins will be relevant to use of TSPs in synthetic extracellular matrices or tissue engineering. In contrast, the neofunctions of vertebrate TSPs likely include interactions suitable for therapeutic targeting without general disruption of ECM.

Abstract
The molecular events in the ovaries of Fenneropenaeus merguiensis De Man during vitellogenesis were investigated. The ribosomal protein L10a (RPL10a) was characterized and cloned. It consisted of 669 bp and the deduced polypeptide had 217 amino acids (GeneBank/EBI accession number FJ623402). The calculated molecular mass and pI were 25.7 kDa and 10.06, respectively. An immunohistochemical technique showed that RPL10a was located in the cytoplasm and nucleus of developing oocytes and follicle cells. Treatment of undeveloped ovarian explant cultures with recombinant histidine (His)-RPL10a stimulated the expression of translationally controlled tumor protein (TCTP), heat shock protein 70 (HSP70), and shrimp ovarian peritrophin (SOP) genes, previously shown to be involved in ovarian maturation. The transcripts of all three genes in the ovarian explants showed their highest expression after 4 h incubation with the His-RPL10a at 37 degrees C. The TCTP and HSP70 transcripts declined after 12 h, while the transcript of SOP remained high until 24 h. The His-RPL10a did not stimulate the expression of the TCTP, SOP, and HSP70 genes in shrimp muscle tissue. The information on the molecular behavior of the RPL10a in this study may, in the future, lead to new methods to stimulate ovarian development in shrimp.

Abstract
The ovary of triploid shrimp Fenneropenaeus chinensis was apparently impaired compared to that of the diploid shrimp at the same age. Therefore triploid shrimp ovary is possible to be taken as a model to understand the mechanism of ovary development of shrimp compared to that of the ovary of diploid shrimp at the same age. In the present study, a suppression subtractive hybridization (SSH) technique was applied to identify differentially expressed genes in the ovary between diploid and triploid shrimp. For the forward library (RNA from the ovary of triploid shrimp as the tester), 54 genes were identified. For the reverse library (RNA from the ovary of diploid shrimp as the tester), 16 genes were identified. The identified genes encoded proteins with multiple functions, including extracellular matrix components, cytoskeleton, cell growth and death, metabolism, genetic information processing, signal transduction/transport or immunity related proteins. Eleven differentially expressed genes were selected to be confirmed in the ovaries of triploid and diploid shrimp by semi-quantitative RT-PCR. Genes encoding spermatogonial stem-cell renewal factor, cytochrome c oxidase subunits I and II, clottable protein, antimicrobial peptide and transposase showed up-regulated expressions in the ovary of triploid shrimp. Genes encoding tubulin, cellular apoptosis susceptibility protein, farnesoic acid O-methyltransferase, thrombospondin and heat shock protein 90 genes showed higher expressions in the ovary of diploid shrimp. The differential expressions of the above genes are suggested to be related to the ovary development of shrimp. It will provide a new clue to uncover the molecular mechanisms underlying the ovarian development in penaeid shrimp.

Abstract
Expressed sequence tags (ESTs) were established from various tissues of the giant tiger shrimp (Penaeus monodon). To simultaneously examine expression patterns of a large number of transcripts in ovaries and testes of P. monodon, a cDNA microarray (ReproArray(GTS)) containing 4992 features amplified from cDNAs of ovary (1920) and testis (3072) EST libraries was constructed and subjected to high-throughput gene expression analysis in four different stages of ovarian development (previtellogenesis, vitellogenesis, early cortical rod and late cortical rod stages). Several transcripts were found to be differentially expressed during P. monodon ovarian development. Among many important reproduction-related genes with differential expression from microarray data, nuclear autoantigenic sperm protein (NASP) was further characterized by RACE-PCR. The full-length cDNA of P. monodon NASP (PmNASP) was 2126 bp in length containing an open reading frame (ORF) of 1812 bp corresponding to a deduced protein of 603 amino acids with 5? and 3?UTRs of 93 and 202 bp (excluding the poly A tail), respectively. Higher PmNASP transcript levels at later stages of ovarian development was consistently confirmed by quantitative real-time PCR. This study indicated that ReproArray(GTS) is effective for high-throughput screening of genes that play important roles in ovarian development of P. monodon.

Abstract
The lymphoid organ of penaeid shrimps is proposed to play an important role in the innate immune system. To investigate the potential immune function of the lymphoid organ, we analyzed the expressed genes from the lymphoid organ of normal and Vibrio harveyi-infected Penaeus monodon using an expressed sequence tag (EST) approach. Sequence analysis of the EST clones derived from the two lymphoid organ cDNA libraries (408 clones from the normal and 625 clones from the infected libraries), revealed a high redundancy of specific transcripts. Transcripts of the lysosomal cysteine proteinases, cathepsins B and L, were abundantly expressed in the lymphoid organ of both libraries, whilst the transcripts of the related genes peritrophin and thrombospondin predominated and were found only in the V. harveyi-infected library, making them interesting candidate functional genes. Moreover, immune-related genes were found at a significant proportion (approximately 15%) in both normal and infected libraries, but different expressed genes were observed between the two libraries. The expression levels of P. monodon cathepsins B and L in the lymphoid organ following injection with either V. harveyi or white spot syndrome virus (WSSV) showed only a slight change in the transcript abundance compared to that seen in the mock-infection (control). Immunohistochemistry confirmed that cathepsin L protein was localized in the lymphoid organ with intense cathepsin L staining observed in the lymphoid organ spheroids of WSSV-infected shrimps. The results suggest that cathepsins L and B likely play a major role in the lymphoid organ function and are probably implicated in degradation of foreign material that is sequestrated in the lymphoid organ spheroids, although any additional role in control of viral or cellular mediated apoptosis remains to be evaluated.

Abstract
In order to identify genes involved in oogenesis and spermatogenesis in penaeid shrimp Marsupenaeus japonicus, a modified annealing control primer (ACP) system was adapted to identify genes differentially expressed in ovary and testis at different developmental stages. By using 20 pairs of ACP primers, 8 differentially expressed genes were obtained. One of these genes is ubiquitin-conjugating enzyme E2r (UBE2r). Bioinformatics analyses show that this gene encodes a protein of 241 amino acids with a predicted molecular mass of 27.4 kDa. Real time PCR analyses demonstrated that the expression level changed significantly in the developing testis and ovary. In the stage 2 of testis, it reached its highest expression level, the lowest expression level present in the stage 1 of ovary. The significantly different expression levels in developing testis and ovary suggest that UBE2r has an important role in oogenesis and spermatogenesis. This article is the first report of UBE2r in crustaceans and also is the first report showing that UBE2r is differentially expressed at different stages of the developing ovary and testis in an animal.

Abstract
Thrombospondins are large secreted, multimodular, calcium-binding glycoproteins that have complex roles in mediating cellular processes. Determination of high-resolution structures of thrombospondins has revealed unique and interesting protein motifs. Here, we review this progress and discuss implications for function. By combining structures of modules from thrombospondins and related extracellular proteins it is now possible to prepare an overall model of the structure of thrombospondin-1 and thrombospondin-2 and discern features of other thrombospondins.

Abstract
Thrombospondins (TSPs) are an evolutionarily ancient family of extracellular calcium-binding glycoproteins. The five mammalian TSPs collectively have important roles in angiogenesis and vascular biology, synaptogenesis, wound repair and connective tissue organisation. Their complex functions relate to the multiple postsecretion fates of TSPs that can involve endocytic uptake, proteolysis or retention within the extracellular matrix (ECM). Surprisingly, the molecular and cellular mechanisms by which TSPs become retained within the ECM are poorly understood. We hypothesised that the highly conserved TSP C-terminal domain mediates ECM retention. We report that ECM incorporation as insoluble punctate deposits is an evolutionarily conserved property of TSPs. ECM retention of TSP1 is mediated by the C-terminal region in trimeric form, and not by C-terminal monomer or trimers of the N-terminal domain or type 1 repeats. Using a novel mRFP-tagged TSP1 C-terminal trimer, we demonstrate that ECM retention involves the RGD site and a novel site in the L-lectin domain with structural similarity to the ligand-binding site of cargo transport proteins. CD47 and beta1 integrins are dispensable for ECM retention, but beta1 integrins enhance activity. These novel data advance concepts of the molecular processes that lead to ECM retention of TSP1.

Abstract
The formation of cortical rod structures is a characteristic of fully mature oocytes in penaeid prawns, but such structures are absent from oocytes of giant freshwater prawn Macrobrachium rosenbergii. In the present study, we first demonstrated the presence of a 30-kDa protein, which was immunologically related to kuruma prawn cortical rod protein (CRP), in the ovary of giant freshwater prawn, and subsequently purified this protein. Furthermore, a cDNA encoding the CRP-like protein was isolated. Based on the high homology (98%) in the amino acid sequence with kuruma prawn CRP, the 30-kDa protein has been identified as a CRP homologue of giant freshwater prawn, designated mrCRP. The RT-PCR analysis revealed that mrCRP mRNA was present in the ovary from a prawn with a gonadosomatic index (GSI) of 0.2. Western blot analysis revealed the presence of a CRP-immunoreactive band of 30kDa in the ovary with GSI of 1.6. By immunocytochemistry, CRP-immunopositive signals were detected in the ovary with GSI of 0.9, that had started to accumulate considerable amounts of vitellins and lipids in the peripheral cytoplasm. With progress of vitellogenesis, mrCRP was apparently accumulated in the mature oocytes, although it was not detectable, presumably because a relatively small amount of mrCRP was masked with large amounts of vitellin and lipids. In giant freshwater prawn without forming cortical rod structures, our findings indicate that the oocytes produce mrCRP, a homologue of CRP found in penaeid prawns.

Abstract
Sex-related genes expressed in vitellogenic ovaries of the giant tiger shrimp, Penaeus monodon, were identified by an EST approach. A total of 1051 clones were unidirectionally sequenced from the 5 terminus. Nucleotide sequences of 743 EST (70.7%) significantly matched known genes previously deposited in the GenBank (E-value <10(-4)) whereas 308 ESTs (29.3%) were regarded as newly unidentified transcripts (E-value >10(-4)). A total of 559 transcripts (87 contigs and 472 singletons) were obtained. Thrombospondin (TSP) and peritrophin (79 and 87 clones accounting for 7.5 and 8.3% of clones sequenced, respectively) predominated among characterized transcripts. Several full length transcripts (e.g. cyclophilin, profillin and thioredoxin peroxidase) were also isolated. A gene homologue encoding chromobox protein (PMCBX, ORF of 567 nucleotides encoding a protein of 188 amino acids) which is recognized as a new member of the HP1 family was identified. Expression patterns of 14 of 25 sex-related gene homologues in ovaries and testes of P. monodon broodstock were examined by RT-PCR. Female sterile and ovarian lipoprotein receptor homologues were only expressed in ovaries whereas the remaining transcripts except disulfide isomerase related P5 precursor and adenine nucleotide translocator 2 were higher expressed in ovaries than testes of P. monodon broodstock. A homologue of ubiquitin specific proteinase 9, X chromosome (Usp9X) revealed a preferential expression level in ovaries than testes of broodstock-sized P. monodon (N = 13 and 11, P <0.05) but was only expressed in ovaries of 4-month-old shrimp (N = 5 for each sex).

Abstract
Shrimp ovarian peritrophin (SOP), a major protein in jelly layer (JL) and cortical rods (CRs), is proposed to play a role in the protection of spawned eggs. The full sequence of SOP cDNA from Fenneropenaeus merguiensis (Fm-SOP) shares approximately 50% identity with other SOP sequences and contains several putative chitin-binding or peritrophin-A domains. Interestingly, Fm-SOP contains a putative 61-amino acid propeptide located at the N-terminal end, downstream of a 19-amino acid signal peptide, which is unique among penaeid SOP sequences described so far. This 61-amino-acid sequence constitutes a putative chitin-binding domain with six conserved cysteines, and is cleaved at a dibasic recognition site for a furin (subtilisin-like endoprotease). Expression analyses indicated that Fm-SOP mRNA is abundant in early vitellogenic ovaries and scarce in late-vitellogenic ovaries. Conversely, Fm-SOP protein is the most abundant at the end of vitellogenesis. To investigate its biological function, a recombinant Fm-SOP was expressed to generate a glycosylated protein in Spodoptera frugiperda Sf9 cells (rSOP-Sf9) and a nonglycosylated protein (rSOP-Ec) in Escherichia coli. rSOP-Sf9 and rSOP-Ec were found to bind to chitin, similarly to the native protein extracted from F. merguiensis ovaries. Most interestingly, rSOP-Ec displayed a chitinase activity and efficiently inhibited the growth of Vibrio harveyi and Staphylococcus aureus, with minimum inhibitory concentrations of 2.4 and 15.7 microM, respectively. This first report shows that a major component of CR and JL is biologically active against known pathogens and predicts a significant role of JL in the protection of the spawned eggs against pathogens.

Abstract
To understand the molecular events of ovarian development in penaeid shrimp, RNA arbitrarily primed polymerase chain reaction (RAP-PCR) was used to identify differentially expressed genes during ovarian maturation in Metapenaeus ensis. From a screening of 700 clones in a cDNA library of the shrimp ovary by the products of RAP-PCR of different maturation stages, 91 fragments with differentially expressed pattern as revealed by dot-blot hybridization were isolated and sequenced. Forty-two of these fragments show significant sequence similarity to known gene products and the differentially expressed pattern of 10 putative genes were further characterized via Northern hybridization. Putative glyceraldehyde-3-phosphate dehydrogenase and arginine kinase are related to provision of energy for active cellular function in oocyte development. Translationally controlled tumor protein, actin, and keratin are related to the organization of cytoskeleton to accomplish growth and development of oocytes. High mobility group protein DSP1, heat shock protein 70, and nucleoside diphosphate kinase may act as repressors before the onset of ovarian maturation. Peptidyl-prolyl cis-trans isomerase and glutathione peroxidase are related to the stabilization of proteins and oocytes. This study provides new insights on the molecular events in the ovarian development in the shrimp.

Abstract
In order to identify genes involved in oogenesis in shrimp, an ovarian cDNA library of Marsupenaeus japonicus was screened using a suppression-subtraction hybridization (SSH)-enriched probe. More than 20 genes were identified as differentially expressed genes between the ovary and the testis. Unexpectedly, one of these genes is a ribosomal protein that is normally considered a housekeeping gene. Northern blot shows that the shrimp ribosomal protein L24 gene (srpl24) is 0.6 kb in length. The expression level of srpl24 in the ovary is much higher than in the testis. Bioinformatics analyses show that srpl24 encodes a protein of 164 aa with a predicted molecular mass of 18.2 kDa, which is a cytoplasmic ribosomal protein. Real time PCR analyses demonstrated that the relative abundance of srpl24 mRNA in the different organs is: ovary >> testis, hepatopancreas, muscle and eye. The highest expression level of srpl24 in the ovary suggests that srpl24 has an important role in oogenesis. It is the first reported rpl24 in crustaceans and is the first reported rpl24 that is differentially expressed between the ovary and the testis in animals.

Abstract
BACKGROUND Thrombospondins (TSPs) are evolutionarily-conserved, extracellular, calcium-binding glycoproteins with important roles in cell-extracellular matrix interactions, angiogenesis, synaptogenesis and connective tissue organisation. Five TSPs, designated TSP-1 through TSP-5, are encoded in the human genome. All but one have known roles in acquired or inherited human diseases. To further understand the roles of TSPs in human physiology and pathology, it would be advantageous to extend the repertoire of relevant vertebrate models. In general the zebrafish is proving an excellent model organism for vertebrate biology, therefore we set out to evaluate the status of TSPs in zebrafish and two species of pufferfish. RESULTS We identified by bioinformatics that three fish species encode larger numbers of TSPs than vertebrates, yet all these sequences group as homologues of TSP-1 to -4. By phylogenomic analysis of neighboring genes, we uncovered that, in fish, a TSP-4-like sequence is encoded from the gene corresponding to the tetrapod TSP-5 gene. Thus, all TSP genes show conservation of synteny between fish and tetrapods. In the human genome, the TSP-1, TSP-3, TSP-4 and TSP-5 genes lie within paralogous regions that provide insight into the ancestral genomic context of vertebrate TSPs. CONCLUSION A new model for TSP evolution in vertebrates is presented. The TSP-5 protein sequence has evolved rapidly from a TSP-4-like sequence as an innovation in the tetrapod lineage. TSP biology in fish is complicated by the presence of additional lineage- and species-specific TSP paralogues. These novel results give deeper insight into the evolution of TSPs in vertebrates and open new directions for understanding the physiological and pathological roles of TSP-4 and TSP-5 in humans.

Abstract
Bulked segregant analysis (BSA) and AFLP were used for isolation of genomic sex determination markers in Penaeus monodon. A total of 256 primer combinations were tested against 6-10 bulked genomic DNA of P. monodon. Five and one candidate female- and male-specific AFLP fragments were identified. Female-specific fragments were cloned and further characterized. SCAR markers derived from FE10M9520, FE10M10725.1, FE10M10725.2 and FE14M16340 provided the positive amplification product in both male and female P. monodon. Further analysis of these markers using SSCP and genome walk analysis indicated that they were not sex-linked. In addition, sex-specific (or differential) expression markers in ovaries and testes of P. monodon were analyzed by RAP-PCR (150 primer combinations). Twenty-one and fourteen RAP-PCR fragments specifically/differentially expressed in ovaries and testes of P. monodon were successfully cloned and sequenced. Expression patterns of 25 transcripts were tested against the first stranded cDNA of ovaries and testes of 3-month-old and broodstock-sized P. monodon (N=5 and N=7-10 for females and N=4 and N=5-7 for males, respectively). Five (FI-4, FI-44, FIII-4, FIII-39 and FIII-58) and two (M457-A01 and MII-51) derived RAP-PCR markers revealed female- and male-specific expression patterns in P. monodon. Surprisingly, MII-5 originally found in testes showed a higher expression level in ovaries than did testes of juvenile shrimps but a temporal female-specific pattern in P. monodon adults.

Abstract
In penaeid shrimp species, ovarian development is characterized by the accumulation of a major yolk protein (vitellin) and the formation of cortical rods in the oocytes. The process is considered to be under the control of a neuroendocrine organ in the eyestalk (the X-organ sinus gland complex). In the present study, the synthesis of vitellogenin (VTG, precursor of vitellin) and two kinds of cortical rod proteins (cortical rod protein, CRP; thrombospondin, MjTSP) was induced by bilateral eyestalk ablation (removal of the X-organ sinus gland complex) in immature female kuruma prawn, Marsupenaeus japonicus, and the synthesis process was monitored over a 7-day period after the ablation. The ovarian weight and hemolymph VTG levels increased in the ablated females. The VTG mRNA levels in the ovary increased concomitantly with vitellin accumulation in the ovary after eyestalk ablation. On the other hand, the CRP and MjTSP protein levels in the ovary increased after eyestalk ablation, whereas the CRP and MjTSP mRNA levels in the ovary did not change concomitantly. The results suggest that the regulatory mechanism of gene expression by eyestalk hormones is different between VTG (transcriptional control) and CRP-MjTSP (translational control).

Abstract
Thrombospondins (TSPs) are extracellular, multidomain, calcium-binding glycoproteins that modulate cell behavior in homeostasis and during development, wound-healing, immune response and tumor growth of adult tissues in vertebrates. In invertebrates these proteins are a major component of cortical rods in mature oocytes. A fragment of a thrombospondin-like gene was generated by screening a subtractive cDNA library constructed from the hemocytes of Chinese shrimp, Fennerpenaeus chinensis. The full length F. chinensis cDNA of thrombospondin was cloned by 3'- and 5'-rapid amplification of cDNA ends (3'- and 5'-RACE). The complete cDNA sequence, named Fc-TSP, is 2886 bp and the open reading frame of the cDNA encodes a 938-residue protein that contains three ChtBD2 domains, an EGF domain, a TSP-3 domain and a common TSP-C (CTD) domain. The protein shares a high sequence identity with the mj-TSPa (46.3%), mj-TSPb (46.9%) and mj-TSPc (51.9%) of Marsupenaeus japonicus. The expression and distribution of Fc-TSP in both challenged and unchallenged shrimps were studied by Northern blot, RT-PCR and in situ hybridization. Northern blot analysis showed that the Fc-TSP transcripts were detected in the hemocytes, heart, intestine, stomach and ovary of both challenged and unchallenged shrimps, but the signal was much stronger in the challenged tissues. A strong hybridization signal was detected only in challenged hepatopancreas, with no signal in the unchallenged tissue. The RT-PCR showed that the Fc-TSP was detected in both challenged and unchallenged tissues including the hemocytes, heart, hepatopancreas, stomach, gills, intestine, spermary and ovary. Except for the ovary and spermary, the signal of challenged tissues was relatively stronger than that of unchallenged ones, especially in hepatopancreas. These results suggest that the thrombospondin was upregulated in the hemocytes, heart, intestine and stomach of challenged shrimp, and induced in the hepatopancreas of challenged shrimps. Therefore, Fc-TSP may be involved in the defense responses of the shrimp.

Abstract
The mature penaeid oocytes possess cortical rods that contain two related cortical rod proteins (CRP, 28.6 kDa and 30.5 kDa). In the present study, localization of CRP mRNA and gene expression profiles of CRP and vitellogenin (Vg) during ovarian development were examined in kuruma prawn, Marsupenaeus japonicus, an economically important species for shrimp and prawn farming. Northern blot analysis revealed that CRP mRNA was expressed in the ovary. In situ hybridization showed strong signals for CRP transcripts in the oocytes at early developmental stages in both immature and mature ovaries. Quantitative analysis by real-time polymerase chain reaction revealed that CRP mRNA levels were higher in the previtellogenic and endogenous (primary) vitellogenic stages than in more advanced stages. Unlike CRP mRNA, Vg mRNA levels were low in the ovary and hepatopancreas in previtellogenic females. When the ovary developed into the endogenous vitellogenic stage, ovarian Vg mRNA levels increased significantly, followed by rapid decrease in more advanced stages. The Vg mRNA levels in the hepatopancreas, on the other hand, tended to be high in the exogenous (secondary) vitellogenic and maturation stages, in which ovarian Vg mRNA levels were decreased. Our findings indicate that CRP mRNA is highly expressed before the onset of vitellogenesis, suggesting that the transcription, translation, and cortical-rod formation of CRP occur at different phases of oocyte development. The endogenous vitellogenic stage is a crucial stage for the initiation of CRP and Vg syntheses. The coincidence of these protein syntheses suggests that CRP and Vg syntheses are regulated by closely-related mechanisms.

Abstract
To elucidate the molecular mechanism of oocyte maturation in the kuruma prawn (Marsupenaeus japonicus), subtractive suppression hybridization (SSH) was initially used to identify novel up-regulated genes during the final stages of oocyte maturation, followed by evaluation of the differential expression profile by macroarray and quantitative real-time RT-PCR analyses. The cathepsin C (dipeptidyl peptidase I) gene was thus found to exhibit a significantly higher expression around the onset of cortical rod (CR) formation (early CR stage, appearance of round CRs), progress to a higher mRNA level until the middle CR stage (elongation of CRs), then rapidly revert to a low expression level at the late CR stage (occurrence of germinal vesicle breakdown, GVBD), as also observed at the non-CR stage (previtellogenesis and vitellogenesis). In situ hybridization analyses revealed that the sites of the expression of cathepsin C transcripts in the ovary were distributed in both oocyte and follicle cells, particularly at the early CR stage. A full-length cDNA sequence of this stage-specific gene was subsequently determined by rapid amplification of the cDNA 3' and 5' ends (3' and 5' RACE). The deduced amino acid sequence of the 230-residue mature peptide shared 67-70% identity to the known cathepsin C in mammals. Western blot analysis showed that expression of procathepsin C protein was exclusively at CR stages. The storage site of procathepsin C protein was localized in CRs as revealed by immunohistochemical analysis. This is the first report on the full-length cDNA sequence of cathepsin C and a demonstration of its involvement in the final stages of oocyte maturation in crustacean species.
