[PMID: 38160900 DOI: 10.1016/j.fsi.2023.109347] [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: 11/16/2023] [Revised: 12/22/2023] [Accepted: 12/27/2023] [Indexed: 01/03/2024]
Abstract
Hemocyanin is the main respiratory protein of arthropods and is formed by hexameric and/or oligomeric subunits. Due to changes in the living environment and gene rearrangement, various hemocyanin subtypes and subunits evolved in crustaceans. This paper reviews the various hemocyanin subtypes and isoforms in shrimp and analyses published genomic data of sixteen hemocyanin family genes from Litopenaeus vannamei to explore the evolution of hemocyanin genes, subunits, and protein structure. Analysis of hemocyanin subtypes distribution and structure in various tissues was also performed and related to multiple and tissue-specific functions, i.e., immunological activity, immune signaling, phenoloxidase activity, modulation of microbiota homeostasis, and energy metabolism. The functional diversity of shrimp hemocyanin due to molecular polymorphism, transcriptional regulation, alternative splicing, degradation into functional peptides, interaction with other proteins or genes, and structural differences will also be highlighted for future research. Inferences would be drawn from other crustaceans to explain how evolution has changed the structure-function of hemocyanin and its implication for evolutionary research into the multifunctionality of hemocyanin and other related proteins in shrimp.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2024; 151:105087.

Abstract
Hemocyanin is a respiratory protein, it is also a multifunctional immune molecule that plays a vital role against pathogen invasion in shrimp. However, the regulation of hemocyanin gene expression in shrimp hemocytes and the mechanisms involved during pathogen infection remains unclear. Here, we used DNA pull-down followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify the Yin Yang 1 transcription factor homolog in Penaeus vannamei (PvYY1) as a key factor that modulates transcription of the small subunit hemocyanin gene of P. vannamei (PvHMCs) in hemocytes during Vibrio parahaemolyticus AHPND (VPAHPND) infection. Bioinformatics analysis revealed that the core promoter region of PvHMCs contains two YY1 motifs. Mutational and oligoprecipitation analyses confirmed that PvYY1 could bind to the YY1 motifs in the PvHMCs core promoter region, while truncation of PvYY1 revealed that the N-terminal domain of PvYY1 is essential for the transactivation of PvHMCs core promoter. Besides, the REPO domain of PvYY1 could repress the activity of the PvHMCs core promoter. Overexpression of PvYY1 significantly activates the promoter activity of PvHMCs core promoter, while PvYY1 knockdown significantly decreases the expression level of PvHMCs in shrimp hemocytes and survival rate of shrimp upon infection with VPAHPND. Our present study provides new insights into the transcriptional regulation of PvHMCs by PvYY1 in shrimp hemocytes during bacteria (VPAHPND) infection.

Abstract
The reported genome-walking methods still suffer from some deficiencies, such as cumbersome experimental steps, short target amplicon, or deep background. Here, a simple and practical fork PCR was proposed for genome-walking. The fork PCR employs a fork primer set of three random oligomers to implement walking task. In primary fork PCR, the low-stringency amplification cycle mediates the random binding of primary fork primer to some places on genome, producing a batch of single-stranded DNAs. In the subsequent high-stringency amplification, the target single-strand is processed into double-strand by the site-specific primer, but a non-target single-stranded DNA cannot be processed by any primer. As a result, only the target DNA can be exponentially amplified in the remaining high-stringency cycles. Secondary/tertiary nested fork PCR(s) further magnifies the amplification difference between the both DNAs by selectively enriching target DNA. The applicability of fork PCR was validated by walking several gene loci. The fork PCR could be a perspective substitution for the existing genome-walking schemes.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 145:104723.

Abstract
Hemocyanin, a copper-containing respiratory protein, is abundantly present in hemolymph of arthropods and mollusks and performs a variety of immunological functions. However, the regulatory mechanisms of hemocyanin gene transcription remain largely unclear. Our previous work showed that knockdown of the transcription factor CSL, a component of the Notch signaling pathway, downregulated the expression of Penaeus vannamei hemocyanin small subunit gene (PvHMCs), indicating the involvement of CSL in regulating the PvHMCs transcription. In this study, we identified a CSL binding motif ("GAATCCCAGA", +1675/+1684 bp) in the core promoter of PvHMCs (designated as HsP3). Dual luciferase reporter assay and electrophoretic mobility shift assay (EMSA) demonstrated that the CSL homolog in P. vannamei (PvCSL) could directly bind and activate the HsP3 promoter. Moreover, in vivo silencing of PvCSL significantly attenuated the mRNA and protein expression of PvHMCs. Finally, in response to Vibrio parahaemolyticus, Streptococcus iniae and white spot syndrome virus (WSSV) challenge, the transcript of PvCSL and PvHMCs showed a positive correlation, suggesting that PvCSL could also modulate the expression of PvHMCs upon pathogen stimulation. Taken together, our present finding is the first to demonstrate that PvCSL is a crucial factor in transcriptional control of PvHMCs.

Abstract
The cellular transcription factors are known to play important roles in virus infection. The present study cloned and characterized a transcription factor CCAAT/Enhancer-binding protein homolog from the shrimp Penaeus vannamei (designates as PvCEBP), and explored its potential functions in white spot syndrome virus (WSSV) infection. PvCEBP has an open reading frame (ORF) of 864 bp encoding a putative protein of 287 amino acids, which contained a highly C-terminal conserved bZIP domain. Phylogenetic tree analysis showed that PvCEBP was evolutionarily clustered with invertebrate CEBPs and closely related to the CEBP of Homarus americanus. Quantitative real-time PCR (qPCR) analysis revealed that PvCEBP was expressed in all examined shrimp tissues, with transcript levels increased in shrimp hemocytes and gill upon WSSV challenge. Furthermore, knockdown of PvCEBP mediated by RNA interference significantly decreased the expression of WSSV genes and viral loads, while enhanced the shrimp survival rate under WSSV challenge. In silico prediction and reporter gene assays demonstrated that PvCEBP could activate the promoter activity of the viral immediate-early gene ie1. Collectively, our findings suggest that PvCEBP is annexed by WSSV to promote its propagation by enhancing the expression of viral immediate-early genes.

Abstract
Marine organisms are threatened by various environmental contaminants, and nanoplastics (NPs) is one of the most concerned. Studied have shown that NPs has a certain impact on marine organisms, but the specific molecular mechanism is still unclear. At present, researches on the effect of NPs on marine life mostly focus on crustaceans, gastropods, and bivalves. In this study, cephalopod Sepia esculenta larvae were first used to investigate the potential immune response molecular mechanisms caused by PS-NPs (50 nm, 50 mg/L) short-term exposure (4 and 24 h). Through S. esculenta larvae transcriptome profile of gene expression analysis, 548 and 1990 genes showed differential expression at 4 and 24 h after NPs exposure, respectively. GO and KEGG enrichment analysis were performed to find immune related DEGs. Then, the interaction relationship between the immune related DEGs after NPs exposure was known through the constructed protein-protein interaction network. 20 hub genes were found on the base of KEGG pathway numbers involved and protein-protein interaction numbers. This research supply valuable genes for the study of cephalopod immune response caused by NPs, which can help us further uncover the molecular mechanisms of organism against NPs.

Abstract
MAPK and NF-κB pathways are important components of innate immune system in multicellular animals. In some model organisms, the MAP3-kinase TGF-beta-activated kinase 1 (TAK1) have been shown to regulate both MAPK and NF-κB pathways activation to tailor immune responses to pathogens or infections. However, this process is not fully understood in shrimp. In this study, we investigated the effect of TAK1 on MAPK and NF-κB activation in shrimp Litopenaeus vannamei following Vibrio parahaemolyticus infection. We found that shrimp TAK1 could activate c-Jun and Relish, the transcription factors of MAPK pathway and NF-κB pathway, respectively. Specifically, over-expression of shrimp TAK1 was able to strongly induce the activities of both AP-1 and NF-κB reporters. TAK1 was shown to bind several MAP2-kinases, including MKK4, MKK6 and MKK7, and induced their phosphorylations, the hallmarks for MAPK pathways activation. TAK1 knockdown in vivo also inhibited the nuclear translocation of c-Jun and Relish during V. parahaemolyticus infection. Accordingly, ectopic expression of shrimp TAK1 in Drosophila S2 cells increased the cleavage of co-expressed shrimp Relish, and induced the promoter activity of Relish targeted gene Diptericin (Dpt). Furthermore, knockdown of c-Jun and Relish enhanced the sensitivity of shrimp to V. parahaemolyticus infection. These findings indicated that shrimp TAK1 conferred antibacterial protection through regulating the activation of both MAPK pathway and NF-κB pathway, and suggested that the TAK1-MAPK/NF-κB axis could be a potential therapeutic target for enhancing antibacterial responses in crustaceans.

Abstract
Hemocyanin is an important non-specific innate immune defense molecule with phenoloxidase, antiviral, antibacterial, hemolytic, and antitumor activities. To better understand the mechanism of functional diversity, proteomics approach was applied to characterize hemocyanin (HMC) expression profiles from Litopenaeus vannamei. At first, hemocyanin was purified by Sephadex G-100 and DEAE-cellulose (DE-52) columns from shrimp serum, and 34 protein spots were identified as HMC on the 2-DE gels. Furthermore, we found that 9 HMC spots about 75 or 77 kDa were regulated by Streptococcus agalactiae and Vibrio parahaemolyticus infection at 6, 12, and 24 h. In addition, 6 different pathogen-binding HMC fractions, viz., HMC-Mix, HMC-Vp, HMC-Va, HMC-Vf, HMC-Ec, and HMC-Sa, showed different agglutinative and antibacterial activities. Moreover, lectin-blotting analysis showed significant differences in glycosylation level among HMC isomers and bacteria-binding HMC fractions. Particularly, the agglutinative activities of the HMC fractions were almost completely abolished when HMC was deglycosylated by O-glycosidase, which suggest that O-linked sugar chains of HMC played important roles in the innate immune recognition. Our findings demonstrated for the first time that L. vannamei HMC had molecular diversity in protein level, which is closely associated with its ability to recognize diverse pathogens, whereas glycan modification probably contributed to HMC’s diversity and multiple immune activities.

Abstract
The sterol regulatory element binding proteins (SREBPs) transcription factors family, which regulate the expression of genes involved in cellular lipid metabolism and homeostasis, have recently been implicated in various physiological and pathophysiological processes such as immune regulation and inflammation in vertebrates. Consistent with other invertebrates, we identified a single SREBP ortholog in Penaeus vannamei (designated PvSREBP) with transcripts ubiquitously expressed in tissues and induced by lipopolysaccharide (LPS), Vibrio parahaemolyticus and Streptococcus iniae. In vivo RNA interference (RNAi) of PvSREBP attenuated the expression of several fatty acid metabolism-related genes (i.e., cyclooxygenase (PvCOX), lipoxygenase (PvLOX), fatty acid binding protein (PvFABP) and fatty acid synthase (PvFASN)), which consequently decreased the levels of total polyunsaturated fatty acids (ΣPUFAs). In addition, PvSREBP silencing decreased transcript levels of several immune-related genes such as hemocyanin (PvHMC) and trypsin (PvTrypsin), as well as genes encoding for heat-shock proteins (i.e., PvHSP60, PvHSP70 and PvHSP90). Moreover, in silico analysis revealed the presence of SREBP binding motifs on the promoters of most of the dysregulated genes, while shrimp depleted of PvSREBP were more susceptible to V. parahaemolyticus infection. Collectively, we demonstrated the involvement of shrimp SREBP in fatty acids metabolism and immune response, and propose that PvSREBP and PvHMC modulate each other through a feedback mechanism to establish homeostasis. The current study is the first to show the dual role of SREBP in fatty acid metabolism and immune response in invertebrates and crustaceans.

Abstract
Hemocyanin is a respiratory protein that possesses multiple physiological and immunological functions in shrimp. However, the transcriptional regulation of the hemocyanin gene is still poorly understood. Here, the nuclear receptor E75 of Litopenaeus vannamei (LvE75) was identified as one of the transcriptional regulators that modulates the transcription of the small molecular weight hemocyanin gene of L. vannamei (LvHMCs) by inhibiting its core promoter activity in a Dual-luciferase assay. In silico analysis revealed that the core promoter (designated HsP3), which is located at +1517/+1849 bp of LvHMCs contained a putative E75 binding motif ("ACGGAAT", spanning +1812/+1818 bp). Further, LvE75 was shown to inhibit the core promoter activity by direct binding. Importantly, in vivo silencing of LvE75 resulted in a significant upregulation in the mRNA and protein expression of LvHMCs gene. Taken together, our present results provide direct evidence that LvE75 is a transcriptional suppressor of the LvHMCs gene expression.

The krüppel-like factor of Penaeus vannamei negatively regulates transcription of the small subunit hemocyanin gene as part of shrimp immune response. FISH & SHELLFISH IMMUNOLOGY 2020; 100:397-406. [PMID: 32201349 DOI: 10.1016/j.fsi.2020.03.035] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 03/10/2020] [Accepted: 03/17/2020] [Indexed: 06/10/2023]
Abstract
Hemocyanin is a multifunctional respiratory glycoprotein, which has also been implicated in other biological functions in shrimp. Moreover, recent studies have revealed that hemocyanin is also involved in a broad range of immune-related activities in shrimp. However, in spite of the considerable interest in unraveling the reasons behind the multiple immune-related functions of hemocyanin, little is known about its transcriptional regulation. Here, DNA pull-down and Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS) analyses were used to isolate and identify the putative transcription factor(s) that are involved in the transcriptional regulation of the small subunit hemocyanin gene of Penaeus vannamei (PvHMCs). Krüppel-like factor (designated PvKruppel), a zinc finger transcription factor homolog in P. vannamei, was identified among the putative transcription factors, while bioinformatics analysis revealed the presence of Krüppel-like factor binding site (KLF motif) on the core promoter region of PvHMCs. Mutational analysis and electrophoretic mobility shift assay (EMSA) confirmed that PvKruppel could bind to the KLF motif on the core promoter region of PvHMCs. Moreover, in response to lipopolysaccharide (LPS), Vibrio parahaemolyticus and white spot syndrome virus (WSSV) challenge, transcript levels of PvKruppel and PvHMCs were negatively correlated. Furthermore, overexpression of PvKruppel significantly reduced the promoter activity of PvHMCs, while PvKruppel knockdown by RNA interference or lipopolysaccharides (LPS) stimulation resulted in a significant increase in the transcript level of PvHMCs. Taken together, our present study provides mechanistic insights into the transcriptional regulation of PvHMCs by PvKruppel during shrimp immune response to pathogens.

FISH & SHELLFISH IMMUNOLOGY 2019; 87:346-359. [PMID: 30677515 DOI: 10.1016/j.fsi.2019.01.023] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 01/09/2019] [Accepted: 01/13/2019] [Indexed: 06/09/2023]
Abstract
To better understand the immune system of shrimp, this study combined PacBio isoform sequencing (Iso-Seq) and Illumina paired-end short reads sequencing methods to discover full-length immune-related molecules of the Pacific white shrimp, Litopenaeus vannamei. A total of 72,648 nonredundant full-length transcripts (unigenes) were generated with an average length of 2545 bp from five main tissues, including the hepatopancreas, cardiac stomach, heart, muscle, and pyloric stomach. These unigenes exhibited a high annotation rate (62,164, 85.57%) when compared against NR, NT, Swiss-Prot, Pfam, GO, KEGG and COG databases. A total of 7544 putative long noncoding RNAs (lncRNAs) were detected and 1164 nonredundant full-length transcripts (449 UniTransModels) participated in the alternative splicing (AS) events. Importantly, a total of 5279 nonredundant full-length unigenes were successfully identified, which were involved in the innate immune system, including 9 immune-related processes, 19 immune-related pathways and 10 other immune-related systems. We also found wide transcript variants, which increased the number and function complexity of immune molecules; for example, toll-like receptors (TLRs) and interferon regulatory factors (IRFs). The 480 differentially expressed genes (DEGs) were significantly higher or tissue-specific expression patterns in the hepatopancreas compared with that in other four tested tissues (FDR <0.05). Furthermore, the expression levels of six selected immune-related DEGs and putative IRFs were validated using real-time PCR technology, substantiating the reliability of the PacBio Iso-seq results. In conclusion, our results provide new genetic resources of long-read full-length transcripts data and information for identifying immune-related genes, which are an invaluable transcriptomic resource as genomic reference, especially for further exploration of the innate immune and defense mechanisms of shrimp.

Transcriptome analysis of differential expressed genes in hepatopancreas of Procambarus clarkii challenged with peptidoglycan. FISH & SHELLFISH IMMUNOLOGY 2019; 86:311-318. [PMID: 30465916 DOI: 10.1016/j.fsi.2018.11.048] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2018] [Revised: 11/12/2018] [Accepted: 11/17/2018] [Indexed: 06/09/2023]
Abstract
Procambarus clarkii is one of the most economically important species in Chinese aquaculture, and is widely cultured. Infection of P. clarkii populations with bacterial pathogens causes high mortality and great economic loss, therefore disease control is of significant economic importance. P. clarkii is a model system for studying immune responses in invertebrates, and its immune system consists solely of the innate response. In the present study, we examined gene expression related to immune function in P. clarkii in response to pathogen challenge. The transcriptome of hepatopancreas tissue from P. clarkii challenged with peptidoclycan (PGN) was analyzed and compared to control specimens. After assembly and annotation, 48,661 unigenes were identified with an average length of 671.54 bp. A total of 2533 differentially expressed genes (DEGs) were obtained, including 765 significantly up-regulated unigenes and 1757 significantly down-regulated unigenes. Gene ontology (GO) analysis demonstrated 19 biological process subcategories, 16 cellular component subcategories, and 17 molecular function subcategories that were enriched among these DEGs. Enrichment analysis using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database revealed enrichment among immune responses pathways. Taken together, this study not only enriches the existing P. clarkii transcriptome database, but also elucidates immune responses of crayfish that are activated in response to PGN challenge.
