Differential expression of sNPF in male and female eyestalk leading to sex dimorphism of AMP expression in Procambarus clarkii intestine. FISH & SHELLFISH IMMUNOLOGY 2024; 151:109735. [PMID: 38945414 DOI: 10.1016/j.fsi.2024.109735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 06/24/2024] [Accepted: 06/27/2024] [Indexed: 07/02/2024]
Abstract
Antimicrobial peptide (AMP) is an important component of crustaceans' innate immune system. In this study, a short neuropeptide F (sNPF) gene (Pc-sNPF) and a Forkhead box O (FOXO) gene (PcFOXO) from Procambarus clarkii were identified. Analysis findings showed that the expression level of AMP genes differed between male and female P. clarkii. Furthermore, Pc-sNPF and PcFOXO were related to the sex dimorphism of AMP. Knockdown of Pc-sNPF in the eyestalk significantly upregulated the expression of PcFOXO and two anti-lipopolysaccharide factors (PcALF4 and PcALFL) in the intestine of P. clarkii. The expression of PcFOXO in the intestine of female P. clarkii was higher than in that of males. Results from RNA interference revealed that PcFOXO positively regulated the expression of PcALF4 and PcALFL in the intestine of male and female P. clarkii. In summary, our study showed that differences in Pc-sNPF expression in eyestalk of male and female P. clarkii leading to sex dimorphism of AMP expression in the intestine are mediated by the sNPF-FOXO-AMP signal pathway called the eyestalk-intestine axis.

Int J Mol Sci 2024; 25:8152. [PMID: 39125723 PMCID: PMC11311334 DOI: 10.3390/ijms25158152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2024] [Revised: 07/23/2024] [Accepted: 07/24/2024] [Indexed: 08/12/2024] Open
Abstract
Sexually dimorphic traits such as growth and body size are often found in various crustaceans. Methyl farnesoate (MF), the main active form of sesquiterpenoid hormone in crustaceans, plays vital roles in the regulation of their molting and reproduction. However, understanding on the sex differences in their hormonal regulation is limited. Here, we carried out a comprehensive investigation on sexual dimorphic responses to MF in the hepatopancreas of the most dominant aquacultural crustacean-the white-leg shrimp (Litopenaeus vannamei). Through comparative transcriptomic analysis of the main MF target tissue (hepatopancreas) from both female and male L. vannamei, two sets of sex-specific and four sets of sex-dose-specific differentially expressed transcripts (DETs) were identified after different doses of MF injection. Functional analysis of DETs showed that the male-specific DETs were mainly related to sugar and lipid metabolism, of which multiple chitinases were significantly up-regulated. In contrast, the female-specific DETs were mainly related to miRNA processing and immune responses. Further co-expression network analysis revealed 8 sex-specific response modules and 55 key regulatory transcripts, of which several key transcripts of genes related to energy metabolism and immune responses were identified, such as arginine kinase, tropomyosin, elongation of very long chain fatty acids protein 6, thioredoxin reductase, cysteine dioxygenase, lysosomal acid lipase, estradiol 17-beta-dehydrogenase 8, and sodium/potassium-transporting ATPase subunit alpha. Altogether, our study demonstrates the sex differences in the hormonal regulatory networks of L. vannamei, providing new insights into the molecular basis of MF regulatory mechanisms and sex dimorphism in prawn aquaculture.

Abstract
Chitinase is a kind of glycoside hydrolase which is widely distributed in nature and encoded by multiple genes to catalyze the decomposition of chitin, which plays an important role in the molting and pathogen defense of crustaceans. However, the research on chitinase in crustaceans is mainly focused on a few species with economic value. In this study, full-length cDNA sequences of the HtCHT1, HtCHT3 and HtCHT4 genes were cloned from the mudflat crab Helice tientsinensis by RACE, and the sequences were analyzed. The results showed that the full-length 2,229 bp of HtCHT1 gene encoded 627 amino acids, while the full-length 2,191 bp of HtCHT3 gene produced 489 amino acids, and the full-length 3,312 bp of HtCHT4 gene encoded 664 amino acids. Bioinformatics analysis showed that all the obtained chitinase proteins had the glycosyl hydrolase family 18 (GH18) catalytic domain and chitin-binding domain (ChtBD2), furthermore, HtCHT1 and HtCHT4 proteins had signal peptide domains at N-terminal. Phylogenetic analysis showed that different types of chitinase were clustered, and HtCHTs were closely related to chitinases in the Eriocheir sinensis. Expression profile analysis showed that the HtCHT1, HtCHT3 and HtCHT4 were significantly expressed in hepatopancreas. Furthermore, the expression of three genes was significantly up-regulated in hepatopancreas after the Vibrio parahaemolyticus challenge. These results suggested that HtCHT1, HtCHT3 and HtCHT4 were belonged to the CHITINASE gene family in H. tientsinensis and were potentially involved in the antibacterial immune response. This study provides essential information for further research of chitinase in H. tientsinensis and even crustaceans.

FISH & SHELLFISH IMMUNOLOGY 2022; 131:454-469.

Abstract
Molting is a basic physiological behavior of the Oriental river prawn (Macrobrachium nipponense), however, the gene expression patterns and immune mechanisms during the molting process of Oriental river prawn are unclear. In the current study, the gene expression levels of the hepatopancreas of the Oriental river prawn at different molting stages (pre-molting, Prm; mid-molting, Mm; and post-molting, Pom) were detected by mRNA sequencing. A total of 1721, 551, and 1054 differentially expressed genes (DEGs) were identified between the Prm hepatopancreas (PrmHe) and Mm hepatopancreas (MmHe), MmHe and Pom hepatopancreas (PomHe) and PrmHe and PomHe, respectively. The results showed that a total of 1151 DEGs were annotated into 316 signaling pathways, and the significantly enriched immune-related pathways were "Lysosome", "Hippo signaling pathway", "Apoptosis", "Autophagy-animal", and "Endocytosis". The qRT-PCR verification results of 30 randomly selected DEGs were consistent with RNA-seq. The expression patterns of eight immune related genes in different molting stages of the Oriental river prawn were analyzed by qRT-PCR. The function of Caspase-1 (CASP1) was further investigated by bioinformatics, qRT-PCR, and RNAi analysis. CASP1 has two identical conserved domains: histidine active site and pentapeptide motif, and the expression of CASP1 is the highest in ovary. The expression levels of triosephosphate isomerase (TPI), Cathepsin B (CTSB) and Hexokinase (HXK) were evaluated after knockdown of CASP1. This research provides a valuable basis to improve our understanding the immune mechanisms of Oriental river prawns at different molting stages. The identification of immune-related genes is of great significance for enhancing the immunity of the Oriental river prawn, or other crustaceans, by transgenic methods in the future.

Abstract
Cyclin A (CycA) plays essential roles in regulating multiple steps of the cell cycle, and it affects gonad development in mammals and invertebrates. Previous RNA interference (RNAi) analysis revealed that knocking-down the expression of CycA in female oriental river prawns (Macrobrachium nipponense) inhibited ovarian development. CycA was also predicted to have regulatory roles in reproductive development of male M. nipponense based on significant changes of Mn-CycA expression after eyestalk ablation. The goal of this study was to investigate the potential functions of CycA in the reproductive development of male M. nipponense using RNAi and histological observations. Quantitative real-time PCR analysis revealed that both single-side and double-side eyestalk ablation stimulated the expressions of Mn-CycA, and the expression was higher in prawns with double-side eyestalk ablation (p < 0.05). Mn-CycA expression was significantly higher in the testis and androgenic gland during the reproductive season than during the non-reproductive season (p < 0.05). In the RNAi analysis, Mn-CycA expression significantly decreased after prawns were injected with dsCycA, and the expression of insulin-like androgenic gland hormone (Mn-IAG) also decreased as Mn-CycA expression decreased. This result indicated that CycA positively regulated the expression of IAG in M. nipponense. Histological observations revealed that the number of sperm decreased dramatically to <5% of the total cells in the testis of the dsCycA-treated group compared to that of control group on day 14, indicating that knockdown of Mn-CycA expression inhibited testis development by affecting the expression of Mn-IAG in M. nipponense. These results highlighted the functions of CycA in male reproductive development of M. nipponense, which can be applied to future studies of male reproduction in other crustacean species.

Abstract
Cyclin B (CycB) plays essential roles in cell proliferation and promotes gonad development in many crustaceans. The goal of this study was to investigate the regulatory roles of this gene in the reproductive development of male oriental river prawns (Macrobrachium nipponense). A phylo-genetic tree analysis revealed that the protein sequence of Mn-CycB was most closely related to those of freshwater prawns, whereas the evolutionary distance from crabs was much longer. A quantitative PCR analysis showed that the expression of Mn-CycB was highest in the gonad of both male and female prawns compared to that in other tissues (p < 0.05), indicating that this gene may play essential roles in the regulation of both testis and ovary development in M. nipponense. In males, Mn-CycB expression in the testis and androgenic gland was higher during the reproductive season than during the non-reproductive season (p < 0.05), implying that CycB plays essential roles in the reproductive development of male M. nipponense. An RNA interference analysis revealed that the Mn-insulin-like androgenic gland hormone expression decreased as the Mn-CycB expression decreased, and that few sperm were detected 14 days after the dsCycB treatment, indicating that CycB positively affects testis development in M. nipponense. The results of this study highlight the functions of CycB in M. nipponense, and they can be applied to studies of male reproductive development in other crustacean species.

Abstract
Over recent years, Macrobrachium amazonicum has become a popular species for shrimp farming due to their fast growth, high survival rates, and marketability. Several studies have focused on the development of new technology for the culture of this species, but many aspects of their nutrition and physiology remain unknown. Thus, the goal of the present study was to obtain transcripts of putative genes encoding digestive enzymes, based on a library of the cDNA from the hepatopancreas of M. amazonicum, sequenced in the Ion TorrentTM platform. We identified fragments of nine genes related to digestive enzymes, acting over proteins, carbohydrates and lipids. Endo and exoproteases were also recorded in the hepatopancreas, indicating adaptation to the digestion of protein-rich foods. Nonetheless, the enzymes involved in the carbohydrate metabolism formed the largest functional group in M. amazonicum, including enzymes related to the digestion of starch, chitin, and cellulose. These findings indicate that the species has a genetic apparatus of a well-adapted omnivorous animal. This information may provide important insights for the selection of ingredients for the formulation of a more appropriate diet to the enzymatic repertoire of M. amazonicum.

Abstract
Polo-like kinase 1 (Plk1) has multiple functions in the cell cycle, including in the maturation of centrosomes during the G2/M transition, the separation of centrosomes, and the activation of cyclin-dependent kinase 1 expression and spindle assembly. In this study, we investigated the potential regulatory roles of Plk1 in the reproductive development of the male oriental river prawn (Machrobrachium nipponense). The full cDNA sequence of Mn-Plk1 was 2360 base pairs long, with an open reading frame of 1836 base pairs encoding 611 amino acids. Protein sequence alignment identified a conserved serine/threonine kinase domain and two Polo-boxes. Phylogenetic tree analysis revealed that Mn-Plk1 had the closest evolutionary distance with Plk1s of freshwater prawns and then with those of crustacean species, whereas the evolutionary distance with mollusks was much more distant. Quantitative PCR analysis predicted that Mn-Plk1 plays essential roles in the regulation of gonad development. RNA interference analysis and histological observations showed that expression of insulin-like androgenic gland hormone decreased as the expression of Mn-Plk1 decreased, and fewer than 5% of cells were sperm cells at day 14 in the dsPlk1 injected prawns. This result indicated that Plk1 positively regulated testis development in M. nipponense by affecting the expression of this hormone. Our results highlight the functions of Plk1 in M. nipponense and provide valuable information that can be applied to establish artificial techniques to regulate testis development in this species.

Identification of candidate genes from androgenic gland in Macrobrachium nipponense regulated by eyestalk ablation. Sci Rep 2021; 11:19855. [PMID: 34615913 PMCID: PMC8494903 DOI: 10.1038/s41598-021-99022-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Accepted: 09/17/2021] [Indexed: 11/28/2022] Open
Abstract
The eyestalk of crustaceans, such as Macrobrachium nipponense, contains many neurosecretory hormones affecting the process of reproduction, molting, metabolism of glucose, and other functions. In this study, important metabolic pathways and candidate genes involved in male sexual development were selected from M. nipponense. The methodology involved performing long-read and next generation transcriptome sequencing of genes from the androgenic gland after eyestalk ablation. qPCR analysis revealed that the mRNA expression of Mn-IAG was significantly increased after ablation of both the single-side (SS) and double-side (DS) eyestalk, compared with the control group (CG). The long-read transcriptome generated 49,840 non-redundant transcripts. A total of 1319, 2092 and 4351 differentially expressed genes (DEGs) were identified between CG versus SS, SS versus DS and CG versus DS, respectively. These data indicated that ablation of the double-sided eyestalk played stronger regulatory roles than the single-side ablation on male sexual development in M. nipponense. This was consistent with the qPCR analysis. Cell Cycle, Cellular Senescence, Oxidative Phosphorylation, Glycolysis/Gluconeogenesis and Steroid Hormone Biosynthesis were the primary enriched metabolic pathways in all three comparisons, and the important genes from these metabolic pathways were also selected. qPCR permitted secondary confirmation of ten DEGs identified through RNA-seq. RNAi-mediated silencing analyses of Hydroxysteroid dehydrogenase like 1 (HSDL1) revealed that HSDL1 has a positive regulatory effect on testes development. This study provides valuable insight into male sexual development in M. nipponense, including metabolic pathways and genes, paving the way for advanced studies on male sexual development in this species and in other crustaceans.

Abstract
The eyestalk of crustacean species secretes many hormones, affecting the process of reproduction, molting, metabolism of glucose, and other functions in crustaceans. In this study, important metabolic pathways and candidate genes involved in the male sexual development were identified through performing the transcriptome profiling analysis of the testis after the ablation of eyestalk from Macrobrachium nipponense. The histological observations revealed that the testis development became vigorous after eyestalk ablation, indicating that the hormones secreted by the eyestalk have negative effects on the testis development in M. nipponense. Transcriptome profiling analysis revealed that 1,039, 1,226, and 3,682 differentially expressed genes (DEGs) were identified between normal prawns (CG) vs single-side eyestalk ablation prawns (SS), SS vs double-side eyestalk ablation prawns (DS), and CG vs DS, respectively, indicating that the ablation of double-side eyestalk has more significant regulatory roles on male sexual development than that of single-side ablation, which was consistent with the histological observations. Lysosome, Apoptosis, Glycolysis/Gluconeogenesis, and Insulin signaling pathway were the main enriched metabolic pathways in all of these three comparisons, and the important genes from these metabolic pathways were also selected. The qPCR verifications of 10 DEGs from these metabolic pathways were the same as those of RNA-seq. The qPCR, in situ hybridization, and RNA interference analysis of Mn-NFkBα revealed that NFkBα has a positive regulatory effect on testis development. This study provided new insights on male sexual development in M. nipponense, promoting the studies on male sexual development in other crustaceans as well.

[PMID: 32142858 DOI: 10.1016/j.gene.2020.144523] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 03/01/2020] [Accepted: 03/02/2020] [Indexed: 01/05/2023]
Abstract
Chitinases play an important role in many biological processes in crustaceans, including molting, digestion, and immunity. In order to further explore the immune defense mechanism of chitinase in Portunus trituberculatus, the PtCht-1 gene was cloned by RACE (rapid-amplification of cDNA ends). This cDNA with a full length of 1910 bp, and an ORF (open reading frame) 1749 bp, coded for 582 amino acid residues and was classified into P. trituberculatus chitinase GH18-group4. It had the typical structural characteristics of GH18 chitinase family. Real-time PCR was used to analyze the expression of PtCht-1 in different tissues, molting stages, after pathogen infection, and low salinity (11‰). PtCht-1 was expressed in all tissues, with the highest expression in the hepatopancreas. In the hepatopancreas of different molting stages, the expression level decreased successively during post-molt stages (A/B), pre-molt stage (D) and inter-molt stage (C). Under normal circumstances, after artificial infection with WSSV and Vibrio parahaemolyticus, the expression of PtCht-1 in hepatopancreas reached the maximum at 48 h, and in hemolymph at 72 h and 24 h, respectively. Overall PtCht-1 expression was up-regulated compared with the control group. Low salinity stress significantly inhibited the expression of PtCht-1, up to 42 folds. Under low salinity stress, the time when WSSV infection reached the peak was markedly delayed by at least 24 h. The results of this study indicate that PtCht-1, as an immune factor, is likely involved in pathogen defense of P. trituberculatus, the immune function of which may be inhibited to some extent after low salinity stress.

Abstract
Chinese mitten crab (Eriocheir sinensis) is an economically important freshwater aquaculture species and is a model species for research on the mechanism of molting. This study aimed to identify important candidate genes associated with the molting process and to determine the role of gills in the regulation of molting with the help of transcriptomic analysis. The transcriptomes of crabs at different molting stages—postmolt (PoM), intermolt (InM), premolt (PrM) and ecdysis (E)—were de novo assembled to generate 246,232 unigenes with a mean length of 851 bp. A total of 86,634 unigenes (35.18% of the total unigenes) were annotated against reference databases. Significantly upregulated genes were identified in postmolt compared to intermolt (1,475), intermolt compared to premolt (65), premolt compared to ecdysis (1,352), and ecdysis compared to postmolt (153), and the corresponding numbers of downregulated genes were 1,276, 32, 1,573 and 171, respectively. Chitin synthase, endochitinase, chitinase A, chitinase 3, chitinase 6 and chitin deacetylase 1 were upregulated during the postmolt and ecdysis stages, while phosphoglucomutase 3 (PGM3), glucosamine 6-phosphate deaminase (GNPDA) and glucosamine glycoside hydrolase (nagZ) were upregulated during the intermolt and premolt stages compared to the other stages. The upregulated genes were enriched in several lipid-related metabolic pathways, such as “fatty acid elongation”, “glycerophospholipid metabolism” and “sulfur metabolism”. Meanwhile, three signaling pathways, including the “phosphatidylinositol signaling system”, the “calcium signaling pathway” and the “GnRH signaling pathway” were also enriched. Tetraspanin-18, an important effector gene in the lysosomal pathway involved in cell apoptosis, up-regulate with the beginning of molting (in premolt stage) and reach the top in the ecdysis stage, and barely expressed in the intermolt stage. The expression variations in the tetraspanin-18 gene indicated that it may play an important role in the beginning of molting cycle, which might be regulated by the stress of salinity. This study revealed that the gills could participate in chitin degradation, in reestablishment of the exoskeleton and the signaling process. Based on transcriptomic analysis of the gills, we not only explored novel molecular mechanisms of molting in E. sinensis but also acquired foundational genetic data for E. sinensis.

Abstract
Risk assessment of heavy metals is important for the health evaluation of inhabiting species in aquatic ecosystem. This study investigated whether chitin exoskeleton of mud crab Macrophthalmus japonicus is affected by heavy metals in estuary sediments in Korea. We compared heavy metal concentrations and analyzed the expression of M. japonicus chitinase genes, which play the crucial role in the formation of chitin exoskeleton. Concentrations of heavy metals were highly observed in crab body inhabiting Hampyeong among estuarine sites. High expressions of chitinase 1 were observed in crab gill and hepatopancreas from Myodo, which is the site with the lowest concentration of heavy metal in crab body. The surface roughness of the exoskeleton decreased with the increased concentration of heavy metals accumulated in the crab body. These results suggest that the total bioconcentration of heavy metals in crabs affected the expression of chitinase genes and changes in the exoskeleton surface roughness.

Abstract
Tolerance of organisms towards heterogeneous and variable environments is highly related to physiological flexibility. An effective strategy to enhance physiological flexibility is the expression of polymorphic enzymes. This seems to be the case in the brown shrimp Crangon crangon. It shows high reproduction rates, feeds opportunistically on endo- and epibenthic organisms, and is apparently well adapted to variable environmental conditions. Previous electrophoretic studies revealed a high level of polymorphism and no consistent phenotype of digestive enzymes between individuals. In order to understand the underlying biochemical processes, we carried out a transcriptome-based study of digestive enzymes of C. crangon. Detailed sequence analyses of triacylglycerol lipase, phospholipase A2, alpha amylase, chitinase, trypsin and cathepsin L were performed to identify putative isoforms. The number of isoforms, and thus the degree of polymorphism varied among enzymes: lipases and carbohydrases showed higher numbers of isoforms in enzymes that besides their extracellular function also have diverse intracellular functions. Furthermore, cysteine proteinases showed a lower polymorphism than serine proteinases. We suggest that the expression of enzyme isoforms improves the efficiency of C. crangon in gaining energy from different food sources.

Abstract
Chitinolytic enzymes are capable to catalyze the chitin hydrolysis. Due to their biomedical and biotechnological applications, nowadays chitinolytic enzymes have attracted worldwide attention. Chitinolytic enzymes have provided numerous useful materials in many different industries, such as food, pharmaceutical, cosmetic, or biomedical industry. Marine enzymes are commonly employed in industry because they display better operational properties than animal, plant, or bacterial homologs. In this mini-review, we want to describe marine chitinolytic enzymes as versatile enzymes in different biotechnological fields. In this regard, interesting comments about their biological role, reaction mechanism, production, functional characterization, immobilization, and biotechnological application are shown in this work.

Abstract
White spot syndrome (WSS) is one of the most damaging phenomena in the culturing of shrimp. To characterize the mechanisms of the molecular responses to WSSV infection in 'Huanghai No. 2'' Fenneropenaeus chinensis, we used next-generation sequencing to observe the transcriptome after oral infection. A total of 108.6 million clean reads were obtained and assembled into 64,103 final unigenes with an average length of 845 bp (N50 = 1534 bp). The assembled unigenes contained 14,263 significant unigenes after BLASTX against the Nr database (E-value cut-off of 10-5). After comparison of digital gene expression data between challenged and control shrimp, a total of 896 DEGs after WSSV infection were identified. Gene pathway analysis indicated that 92, 131 and 142 metabolic pathways were affected at early, peak and late phases respectively. Some pathways were related to the immune response, such as the phagosome, complement and coagulation cascades, the antigen processing and presentation pathway and so on. Many immune-related genes were also identified after pathway analysis. Interestingly, some growth-related genes, such as cathepsin L, myosin regulatory light chain 2 smooth muscle, and alpha-amylase were also differentially expressed after WSSV infection, and the correlation between growth trait and WSSV-resistance trait need further research. The expression patterns of eight DEGs were confirmed by quantitative real-time reverse transcription polymerase chain reaction, and there was good agreement between RNA-seq and qRT-PCR. These data will provide valuable information for characterizing the immune mechanism of the response of shrimp's to WSSV.

Abstract
Chitinase belongs to the glycosyl hydrolases family 18 and plays key role in the development and pathogen resistance of crustaceans. In this study, the enzymatic characterization of chitinase 3C (EcChi3C) of Exopalaemon carinicauda was analyzed. In addition, we analyzed the expression profiles of EcChi3C at different tissues and different molting stages. In the all tested tissues, it was predominantly expressed in hepatopancreas, and then stomach, but poor in other tissues. In all tested molting periods, it was mainly expressed in intermolt and molting stages, but poor in other stages. The results of molting, mortality and the uropod ultrastructure of prawns after being injected with EcChi3C dsRNA were in accordance with those of the control group. In addition, there is no difference for endopodite morphology between the survival and dead individuals in experimental group. After being challenged with bacteria, the expression of EcChi3C was up-regulated significantly at 12 h and followed with a comeback at 96 h. These results suggest that EcChi3C is an important immune related gene but not a necessary gene in the molting process of E. carinicauda.

Abstract
The swimming crab (Portunus trituberculatus) is among the most economically important seawater crustacean species in Asia. Despite its commercial importance and being well-studied status, genomic and transcriptomic data are scarce for this crab species. In the present study, limb bud tissue was collected at different developmental stages post amputation for transcriptomic analysis. Illumina RNA-sequencing was applied to characterise the limb regeneration transcriptome and identify the most characteristic genes. A total of 289,018 transcripts were obtained by clustering and assembly of clean reads, producing 150,869 unigenes with an average length of 956 bp. Subsequent analysis revealed WNT signalling as the key pathway involved in limb regeneration, with WNT4 a key mediator. Overall, limb regeneration appears to be regulated by multiple signalling pathways, with numerous cell differentiation, muscle growth, moult, metabolism, and immune-related genes upregulated, including WNT4, LAMA, FIP2, FSTL5, TNC, HUS1, SWI5, NCGL, SLC22, PLA2, Tdc2, SMOX, GDH, and SMPD4. This is the first experimental study done on regenerating claws of P. trituberculatus. These findings expand existing sequence resources for crab species, and will likely accelerate research into regeneration and development in crustaceans, particularly functional studies on genes involved in limb regeneration.

Abstract
Chitin degradation is catalyzed by a two-component chitinolytic enzyme system, chitinase and β-N-acetylglucosaminidase (NAGase). In this paper, the full-length cDNA sequence encoding NAGase (EcNAG) was obtained from Exopalaemon carinicauda. The deduced amino acid sequence of EcNAG open reading frame (ORF) contained one Glycohydro_20b2 domain and one Glyco_hydro_20 domain. Based on the cDNA sequence, the genomic structure of EcNAG was characterized and it was composed of six exons and five introns. EcNAG mRNA majorly expressed in the hepatopancreas and epidermis. During the molting stages, EcNAG mRNA expression was well-regulated and its expression reached the highest level at the molting stage E. In addition, EcNAG was recombinant expressed in Pichia pastoris and the partial enzymatic characterization of recombinant EcNAG was confirmed. After being challenged with Vibrio parahaemolyticus and Aeromonas hydrophila, the expression of EcNAG was up-regulated significantly at 6 h and reached the peak at 12 h. And then, the expression began to down-regulated and came to the normal level at 72 h. It is helpful to research the relationship between the molt-related hormones and chitinlytic enzymes.

Abstract
Although eyestalk ablation (ESA) is currently considered the most effective method to facilitate molting and maturation, its physiological responses are still not clearly explained in decapod crustaceans. In this study, we analyzed the hepatopancreatic transcriptomes of Litopenaeus vannamei after ESA using the Illumina Miseq platform. After screening 53,029 contigs with high cutoff values (fold change>|10|; P-value<0.05; RPKM>1), we were able to identify 105 differentially expressed genes (DEGs), of which 100 were up-regulated and five were down-regulated. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that many DEGs were involved in the synthetic pathways for glycerol and trehalose, which are known to function as the major protectants under conditions of low temperature and osmotic stress in arthropods. Additional analysis of the other DEGs enabled us to classify them in four categories: immunity; cellular trafficking; transcriptional regulation; molting and maturation. Many DEGs were involved in immunity and stress responses, in particular the proPO activation system, which is the major immune and wound-healing system in arthropods. In addition to immunity and stress responses, we were also able to identify DEGs involved in molting and maturation processes (e.g., group I chitinase), as well as those involved in hormone metabolism and trafficking. Collectively, based on the transcriptomic analysis, ESA causes not only stress and immune responses, but also molting and maturation in L. vannamei. The DEGs identified in this study could be useful markers to understand the physiological responses that ESA induces in shrimp, such as molting, maturation, and immunity.

Abstract
Molting is critical for growth, development, reproduction, and survival in arthropods. Complex neuroendocrine pathways are involved in the regulation of molting and may potentially become targets of environmental endocrine disrupting chemicals (EDCs). Based on several known ED mechanisms, a wide range of pesticides has been developed to combat unwanted organisms in food production activities such as agriculture and aquaculture. Meanwhile, these chemicals may also pose hazards to nontarget species by causing molting defects, and thus potentially affecting the health of the ecosystems. The present review summarizes the available knowledge on molting-related endocrine regulation and chemically mediated disruption in arthropods (with special focus on insects and crustaceans), to identify research gaps and develop a mechanistic model for assessing environmental hazards of these compounds. Based on the review, multiple targets of EDCs in the molting processes were identified and the link between mode of action (MoA) and adverse effects characterized to inform future studies. An adverse outcome pathway (AOP) describing ecdysone receptor agonism leading to incomplete ecdysis associated mortality was developed according to the OECD guideline and subjected to weight of evidence considerations by evolved Bradford Hill Criteria. This review proposes the first invertebrate ED AOP and may serve as a knowledge foundation for future environmental studies and AOP development.

Abstract
Chitinase is a multi-gene family, which play important physiological roles in crustaceans, involved in several biological processes, including digestion, molting and defense against viruses. In the present study, a chitinase-4 gene (PmChi-4) was cloned from Penaeus monodon by rapid amplification of cDNA ends (RACE). The full length of PmChi-4 cDNA was 2178 bp, including an 1815 bp open reading frame (ORF) which encoded 604 amino acid residues. The predicted PmChi-4 protein was 67.7 kDa and shared 61%-88% identity with the type of Chi-4s from other crustaceans. Quantitative real-time (qRT-PCR) analysis indicated that PmChi-4 was expressed ubiquitously with the high expression level in hepatopancreas. PmChi-4 was expressed throughout the whole larvae stages, and the highest level of PmChi-4 transcripts was detected at Mysis3 stage, which indicated that PmChi-4 may be involved in larval metamorphosis. In order to know whether PmChi-4 was related to the immune response of shrimp, Streptococcus agalactiae and Vibrio harveyi were chosen to challenge the shrimp, PmChi-4 transcripts were significantly increased and reached to the maximum at 6 h in hepatopancreas and at 12 h in gill, respectively. The results suggested that PmChi-4 participated in the immune defenses to pathogen infection. Besides, the ammonia nitrogen stress treatment was also carried out, PmChi-4 transcripts were significantly decreased in hepatopancreas and gill and the result showed that PmChi-4 may be involved in ammonia nitrogen stress in P. monodon. Overall, our present study lay a foundation for further research into the biological function and regulation of chitinase in P. monodon.

Abstract
Changes in salinity affect the physiological status of the marine habitat including that of the intertidal mud crab Macrophthalmus japonicus. Chitinases play significant biological roles in crustaceans such as morphogenesis, nutrient digestion, and pathogen defense. In this study, the osmoregulatory function of three chitinase gene transcripts was determined compared to seawater (SW, 31 ± 1 psu) in M. japonicus gills and hepatopancreas under different salinities (10, 25, and 40 psu) for 1, 4, and 7 days. In SW-exposed crab, quantitative real-time PCR analysis showed chitinase 1 (Mj-chi1) and chitinase 4 (Mj-chi4) transcripts constitutively expressed in all the tested tissues with strong expression in hepatopancreas, but chitinase 5 (Mj-chi5) showed highest expression in stomach. When exposed to different salinities, Mj-chi1 showed significant up-regulation at day 4 whereas Mj-chi4 showed late up-regulation (day 7) at all the salinities in hepatopancreas. In the gills, early up-regulation (day 1) in Mj-chi1 and time-dependent late up-regulation (day 7) in Mj-chi4 at high salinity were observed. These results indicate the possibility of using Mj-chi4 as a marker against salinity changes. Moreover, our results further suggest that Mj-chi1 and Mj-chi4 transcriptions were significantly affected by changes in salinity; however, Mj-chi5 in gills was less affected by salinity and showed no effect in hepatopancreas. Thus, chitinase transcription modulations in the gills are more sensitive than hepatopancreas to salinity stress. Further, present data indicate the possible existence of different physiological roles among chitinase gene families, which need to be clarified in more detail by future biochemical and physiological functional studies.

Abstract
In this paper, we purified two native chitinases from the hepatopancreas of the ridgetail white prawn Exopalaemon carinicauda by using ion-exchange resin chromatography (IEC) and gel filtration. These two chitinases, named EcChi1 and EcChi2, were identified by chitinolytic activity assay and LC-ESI-MS/MS. Their apparent molecular weights were 44 kDa and 65 kDa as determined by sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The specific activity of EcChi1 and EcChi2 was 1305.97 U·mg−1 and 28.69 U·mg−1. The optimal temperature and pH of EcChi1 were 37 °C and pH 4.0, respectively. Co2+, Fe3+, Zn2+, Cd2+, and Cu2+ had an obvious promoting effect upon chitinase activity of EcChi1. For colloidal chitin, the Km and Vmax values of EcChi1 were 2.09 mg·mL−1 and 31.15 U·mL−1·h−1.

Abstract
This study aimed to identify differentially expressed genes in Procambarus clarkii crayfish collected from locations of different environmental qualities in the Doñana National Park surrounding areas. The pollution sustained by the crayfish was confirmed by their hepatopancreatic metal concentration. We generated forward and reverse libraries by suppression subtractive hybridization (SSH) to analyze the transcriptional profiles of crayfish from moderately and highly polluted zones in comparison with the control site within the Doñana Biological Reserve. Forty-three differentially expressed genes were detected, and most of them were identified as genes involved in a variety of biological functions, particularly in the innate immune response. To verify the SSH results and assess interindividual variability nine transcripts (ALP, AST, BTF3, CHIT, CTS, ferritin, HC, HC2, and SPINK4) were selected for absolute quantification by real-time qRT-PCR. The qRT-PCR data revealed substantial differences in the absolute amounts of the nine transcripts and confirmed their up- or down-regulation in the polluted sites. Additionally, a positive and significant linear correlation was found between the hepatopancreatic copper concentration and the levels of the transcripts encoding hemocyanins. Finally, the transcriptomic study was complemented with a detailed analysis of SNP profiles of the selected transcripts that revealed point mutations that might underlie adaptive response to environmental stress in P. clarkii. Overall, this work provides novel insights into the molecular pathways that could mediate the response to environmental pollutants in P. clarkii emphasizing the central role of the immune function and thus, should clearly benefit further immunotoxicological research in this organism.

Cell Stress Chaperones 2014; 19:549-58. [PMID: 24408604 PMCID: PMC4041943 DOI: 10.1007/s12192-013-0488-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2013] [Revised: 11/23/2013] [Accepted: 11/25/2013] [Indexed: 12/24/2022] Open
Abstract
Chitinases are essential enzymes for crustaceans and participates in several biological processes, such as nutrient digestion, morphogenesis, pathogenesis, and pathogen defense. In the present study, the full-length cDNA of Chi (named EcChi) was cloned from the hemocytes of ridgetail white prawn Exopalaemon carinicauda by rapid amplification of cDNA ends methods. The full-length cDNA of EcChi was 1,319 bp, including contains a 5'-untranslated region (UTR) of 42 bp, 3'-UTR of 101 bp with a poly (A) tail, an open-reading frame of 1,176 bp, encoding a 391-amino acid polypeptide with the predicted molecular weight of 43.71 kDa and estimated isoelectric point of 4.78. Sequence analysis revealed that the conserved chitinases family 18 active site was predicted in the amino acid sequence of EcChi. BLAST analysis revealed that amino acids of EcChi shared high identity (61-77 %) with that of other crustaceans. Quantitative real-time PCR analysis indicated that EcChi could be detected in all the tested tissues, and strongly expressed in hepatopancreas of E. carinicauda. After challenged with Vibrio anguillarum and WSSV, EcChi transcripts both in hemocytes and hepatopancreas increased significantly in the first 3 h, respectively. These results indicated that EcChi might be involved in the innate immune responses to V. anguillarum and WSSV in E. carinicauda.

PLoS One 2013; 8:e82155. [PMID: 24312639 PMCID: PMC3849447 DOI: 10.1371/journal.pone.0082155] [Citation(s) in RCA: 82] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2013] [Accepted: 10/21/2013] [Indexed: 11/19/2022] Open
Abstract
Background The swimming crab, Portunus trituberculatus, which is naturally distributed in the coastal waters of Asia-Pacific countries, is an important farmed species in China. Salinity is one of the most important abiotic factors that influence not only the distribution and abundance of crustaceans, it is also an important factor for artificial propagation of the crab. To better understand the interaction between salinity stress and osmoregulation, we performed a transcriptome analysis in the gills of Portunus trituberculatus challenged with salinity stress, using the Illumina Deep Sequencing technology. Results We obtained 27,696,835, 28,268,353 and 33,901,271 qualified Illumina read pairs from low salinity challenged (LC), non-challenged (NC), and high salinity challenged (HC) Portunus trituberculatus cDNA libraries, respectively. The overall de novo assembly of cDNA sequence data generated 94,511 unigenes, with an average length of 644 bp. Comparative genomic analysis revealed that 1,705 genes differentially expressed in salinity stress compared to the controls, including 615 and 1,516 unigenes in NC vs LC and NC vs HC respectively. GO functional enrichment analysis results showed some differentially expressed genes were involved in crucial processes related to osmoregulation, such as ion transport processes, amino acid metabolism and synthesis processes, proteolysis process and chitin metabolic process. Conclusion This work represents the first report of the utilization of the next generation sequencing techniques for transcriptome analysis in Portunus trituberculatus and provides valuable information on salinity adaptation mechanism. Results reveal a substantial number of genes modified by salinity stress and a few important salinity acclimation pathways, which will serve as an invaluable resource for revealing the molecular basis of osmoregulation in Portunus trituberculatus. In addition, the most comprehensive sequences of transcripts reported in this study provide a rich source for identification of novel genes in the crab.

Six chitinases from oriental river prawn Macrobrachium nipponense: cDNA characterization, classification and mRNA expression during post-embryonic development and moulting cycle. Comp Biochem Physiol B Biochem Mol Biol 2013; 167:30-40. [PMID: 24096116 DOI: 10.1016/j.cbpb.2013.09.009] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2013] [Revised: 09/26/2013] [Accepted: 09/26/2013] [Indexed: 01/29/2023]
Abstract
Chitinase plays crucial physiological roles in crustaceans, including the digestion of chitin-containing food, moulting and the defense of shrimp against viruses. However, in contrast to insect species, no genome-wide analysis has been carried out in crustacean species and cDNAs encoding chitinase and chitinase-like proteins have been characterized in relatively few species. In this study, we identified six chitinase genes in the oriental river prawn, Macrobrachium nipponense, according to the established expressed sequence tag (EST) information using Rapid Amplification of the cDNA Ends (RACE) technique and homology cloning. We assigned these genes to three different chitinase groupings, which were designated MnCht1A, 1B, 3A, 3B, 3C and 4. The domain organization analysis of the six MnCht proteins revealed that only MnCht3C and MnCht4 possessed full structure, while MnCht1A, 1B, 3A and 3B lacked the serine/threonine (S/T)-rich linker and chitin-binding domains (CBDs). Their expression in different tissues and different developmental stages suggested that all of them have a function in the digestion of chitinous foods, modification of gut peritrophic membrane and degradation of the chitin exoskeleton. Analysis of the stage-specific moulting cycle and different temperature stimulation provided further evidence that MnCht1A, 1B and 3B have pivotal roles in the moulting cycle, while MnCht 4 only assists in the moulting process. This study provides important information for further investigations on the functions of chitinase in M. nipponense and other crustaceans.
