Genome-Wide Identification of Vitellogenin Gene Family and Comparative Analysis of Their Involvement in Ovarian Maturation in Exopalaemon carinicauda. Int J Mol Sci 2024; 25:1089. [PMID: 38256163 PMCID: PMC10815947 DOI: 10.3390/ijms25021089] [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: 11/21/2023] [Revised: 12/29/2023] [Accepted: 01/10/2024] [Indexed: 01/24/2024] Open
Abstract
Vitellogenin (Vtg) is a precursor of yolk proteins in egg-laying vertebrates and invertebrates and plays an important role in vitellogenesis and embryonic development. However, the Vtg family remains poorly characterized in Exopalaemon carinicauda, a major commercial mariculture species found along the coasts of the Yellow and Bohai Seas. In this study, 10 Vtg genes from the genomes of E. carinicauda were identified and characterized. Phylogenetic analyses showed that the Vtg genes in crustaceans could be classified into four groups: Astacidea, Brachyra, Penaeidae, and Palaemonidae. EcVtg genes were unevenly distributed on the chromosomes of E. carinicauda, and a molecular evolutionary analysis showed that the EcVtg genes were primarily constrained by purifying selection during evolution. All putative EcVtg proteins were characterized by the presence of three conserved functional domains: a lipoprotein N-terminal domain (LPD_N), a domain of unknown function (DUF1943), and a von Willebrand factor type D domain (vWD). All EcVtg genes exhibited higher expression in the female hepatopancreas than in other tissues, and EcVtg gene expression during ovarian development suggested that the hepatopancreas is the main synthesis site in E. carinicauda. EcVtg1a, EcVtg2, and EcVtg3 play major roles in exogenous vitellogenesis, and EcVtg3 also plays a major role in endogenous vitellogenesis. Bilateral ablation of the eyestalk significantly upregulates EcVtg mRNA expression in the female hepatopancreas, indicating that the X-organ/sinus gland complex plays an important role in ovarian development, mostly by inducing Vtg synthesis. These results could improve our understanding of the function of multiple Vtg genes in crustaceans and aid future studies on the function of EcVtg genes during ovarian development in E. carinicauda.

Abstract
The banana shrimp is found in the Pacific and Indian Oceans. Female shrimp are preferred for consumption because they are larger than males. Understanding the mechanism of sex differentiation is important for developing techniques to increase the number of female shrimp for economic benefits. This study investigates the reproductive development of F. merguiensis using transcriptome analysis. Sxl2, dsx, AGH, FEM-1, and Nrg-X2 were classified as essential genes for testes development during the juvenile stage. Several genes were required for both juvenile and adult male development. Additionally, the expression of several genes was shown to be required for juvenile and adult ovarian development, including SOP1, SOP2, Ptgr1, EST, Vgr, Vmol1, and TR-beta A. Interestingly, high levels of FoxL2 expression were observed in the testes, in contrast to previous studies in humans and other mammals. The binding of FoxL2 to the Vtg promoter was demonstrated in silico with the highest relative binding score (RS = 0.89) using the JASPAR program. Knock-down of the FoxL2 gene with dsRNA significantly suppressed FoxL2 at 2, 4, and 6 d. As a result, Vtg expression increased when compared with the control at 2, 4, and 6 d, indicating that FoxL2 plays an important role in Vtg expression in the ovary. Our findings highlight the role of FoxL2 in banana shrimp reproduction and provide valuable information on the genes associated with the F. merguiensis reproductive system.

Abstract
Caligus rogercresseyi is the main ectoparasite that affects the salmon industry in Chile. The mechanisms used by the parasite to support its life strategy are of great interest for developing control strategies. Due to the critical role of insect peritrophins in host–parasite interactions and response to pest control drugs, this study aimed to identify and characterize the peritrophin-like genes present in C. rogercresseyi. Moreover, the expression of peritrophin-like genes was evaluated on parasites exposed to delousing drugs such as pyrethroids and azamethiphos. Peritrophin genes were identified by homology analysis among the sea louse transcriptome database and arthropods peritrophin-protein database obtained from GenBank and UniProt. Moreover, the gene loci in the parasite genome were located. Furthermore, peritrophin gene expression levels were evaluated by RNA-Seq analysis in sea louse developmental stages and sea lice exposed to delousing drugs deltamethrin, cypermethrin, and azamethiphos. Seven putative peritrophin-like genes were identified in C. rogercresseyi with high homology with other crustacean peritrophins. Differences in the presence of signal peptides, the number of chitin-binding domains, and the position of conserved cysteines were found. In addition, seven peritrophin-like gene sequences were identified in the C. rogercresseyi genome. Gene expression analysis revealed a stage-dependent expression profile. Notably, differential regulation of peritrophin genes in resistant and susceptible populations to delousing drugs was found. These data are the first report and characterization of peritrophin genes in the sea louse C. rogercresseyi, representing valuable knowledge to understand sea louse biology. Moreover, this study provides evidence for a deeper understanding of the molecular basis of C. rogercresseyi response to delousing drugs.

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
Vitellogenesis in crustaceans is an energy-consuming process. Though the underlying mechanisms of ovarian maturation in decapod Crustacea are still unclear, evidence indicates the process to be regulated by antagonistically-acting inhibitory and stimulating factors specifically originating from X-organ/sinus gland (XO/SG) complex. Among the reported neuromediators, neuropeptides belonging to the crustacean hyperglycemic hormone (CHH)-family have been studied extensively. The structure and dynamics of inhibitory action of vitellogenesis-inhibiting hormone (VIH) on vitellogenesis have been demonstrated in several species. Similarly, the stimulatory effects of other neuropeptides of the CHH-family on crustacean vitellogenesis have also been validated. Advancement in transcriptomic sequencing and comparative genome analysis has led to the discovery of a large number of neuromediators, peptides, and putative peptide receptors having pleiotropic and novel functions in decapod reproduction. Furthermore, differing research strategies have indicated that neurotransmitters and steroid hormones play an integrative role by stimulating neuropeptide secretion, thus demonstrating the complex intertwining of regulatory factors in reproduction. However, the molecular mechanisms by which the combinatorial effect of eyestalk hormones, neuromediators and other factors coordinate to regulate ovarian maturation remain elusive. These multifunctional substances are speculated to control ovarian maturation possibly via the autocrine/paracrine pathway by acting directly on the gonads or by indirectly exerting their stimulatory effects by triggering the release of a putative gonad stimulating factor from the thoracic ganglion. Acting through receptors, they possibly affect levels of cyclic nucleotides (cAMP and cGMP) and Ca2+ in target tissues leading to the regulation of vitellogenesis. The "stimulatory paradox" effect of eyestalk ablation on ovarian maturation continues to be exploited in commercial aquaculture operations, and is outweighed by the detrimental physiological effects of this procedure. In this regard, the development of efficient alternatives to eyestalk ablation based on scientific knowledge is a necessity. In this article, we focus principally on the signaling pathways of positive neuromediators and other factors regulating crustacean reproduction, providing an overview of their proposed receptor-mediated stimulatory mechanisms, intracellular signaling, and probable interaction with other hormonal signals. Finally, we provide insight into future research directions on crustacean reproduction as well as potential applications of such research to aquaculture technology development.

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
The full-length cDNA of bystin isoform 1 (PmBys1) of the giant tiger shrimp Penaeus monodon was characterized. It was 1553 bp in length containing an ORF of 1365 bp corresponding to a polypeptide of 454 amino acids. The level of PmBys1 mRNA in ovaries was greater than that in other tissues of females and in testes of males in both juveniles and wild broodstock (P < .05). In non-ablated wild female broodstock, PmBys1 mRNA significantly and progressively increased in ovaries from stage I of development, peaking at stage IV (P < .05). Its level in stages I-IV of eyestalk-ablated broodstock was greater than that in non-ablated broodstock (P < .05). Injection of exogenous serotonin (50 μg/g body weight) into 18-month-old shrimp resulted in a significantly increase of ovarian PmBys1 mRNA at 6-48 h post injection (hpi) (P < .05). PmBys1 protein (52 kDa) was found in ovarian stages I-V of non-ablated wild broodstock and II-IV of ablated wild broodstock, respectively. Along with the 52 kDa band, immunoreactive bands of 50 and 43 kDa were also observed in ovarian stages II-IV of both non-ablated and ablated broodstock and in ovaries of post-spawning broodstock. The 43 KDa band was not observed in ovarian stage I of wild female broodstock or in premature juveniles. PmBys1 protein was localized in the ooplasm of previtellogenic oocytes, nucleo-cytoplasmic compartments of vitellogenic oocytes and cortical rods of mature oocytes in wild broodstock. The results implied a possible role for PmBys1 during ovarian development 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
Gene expression of reproductive system of the black tiger shrimp (Peneaus monodon) has been widely studied to address poor maturation problem in captivity. However, a systematic evaluation of reference genes in quantitative real-time PCR (qPCR) for P. monodon reproductive organs is lacking. In this study, the stability of four potential reference genes (18s rRNA, GAPDH, β-actin, and EF1-α) was examined in the reproductive tissues in various conditions using bioinformatic tools: NormFinder and geNorm. For NormFinder, EF1-α and GAPDH ranked first and second as the most stable genes in testis groups whereas GAPDH and EF1-α were for ovaries from wild-caught broodstock and domesticated groups. EF1-α and β-actin ranked first and second for the eyestalk ablated ovaries. For geNorm, EF1-α and GAPDH had the best stability in all testis and ovaries from domesticated groups whereas EF1-α and β-actin were the best for ovaries from wild-caught and eyestalk ablated groups. Moreover, the expression levels of two well-known reproductive genes, Dmc1 and Vitellogenin, were used to validate these reference genes. When normalized to EF1-α, the expected expression patterns were obtained in all cases. Therefore, this work suggests that EF1-α is more versatile as reference genes in qPCR analysis for reproductive system in P. monodon.

Abstract
Glycobiology is the study of complex carbohydrates in biological systems and represents a developing field of science that has made huge advances in the last half century. In fact, it combines all branches of biomedical research, revealing the vast and diverse forms of carbohydrate structures that exist in nature. Advances in structure determination have enabled scientists to study the function of complex carbohydrates in more depth and to determine the role that they play in a wide range of biological processes. Glycobiology research in marine systems has primarily focused on reproduction, in particular for what concern the chemical communication between the gametes. The current status of marine glycobiology is primarily descriptive, devoted to characterizing marine glycoconjugates with potential biomedical and biotechnological applications. In this review, we describe the current status of the glycobiology in the reproductive processes from gametogenesis to fertilization and embryo development of marine animals.

JOURNAL OF EXPERIMENTAL ZOOLOGY PART B-MOLECULAR AND DEVELOPMENTAL EVOLUTION 2012; 318:572-85.

Abstract
Vitellogenin (VTG) synthesis in the hepatopancreas and ovary is negatively regulated by vitellogenesis-inhibiting hormone (VIH) produced in the neurosecretory cell of X-organ/sinus gland complex of the eyestalks of penaeid shrimp. Eyestalk ablation is used commercially to induce ovarian maturation in shrimps which leads to an eventual loss of the spawner. The aim of the present study was to understand the molecular mechanism of VIH regulation in ovarian development and its inhibition of VTG gene expression by using a MEK-specific inhibitor (U0126). The real-time quantitative PCR results showed VTG mRNA level was progressively increased in the ovary and hepatopancreas of unilateral eyestalk-ablated and inhibitor-treated shrimps. Western blot analysis also showed that phosphoMEK was detected only in the unilateral eyestalk-ablated and control shrimp, whereas phospho-MEK was not detected in inhibitor-treated shrimp. DAX-1, SF-1, and StAR expression correlated with changes in VIH mRNA and altered phospho-ERK levels. This is consistent with the hypothesis that suppression of DAX-1 results in SF-1-mediated StAR protein upregulation of estradiol that is implicated in vitellogenesis. This is the first report that demonstrates the molecular mechanism of VIH suppression via MEK pathway to induce ovarian maturation in female Penaeus monodon by molecular signal intervention, a less-invasive method than traditional eyestalk ablation.

Abstract
The arthropod cuticle is a multilayered extracellular matrix produced by the epidermis during embryogenesis and moulting. Molecularly and histologically, cuticle differentiation has been extensively investigated in the embryo of the insect Drosophila melanogaster. To learn about the evolution of cuticle differentiation, we have studied the histology of cuticle differentiation during embryogenesis of the amphipod crustacean Parhyale hawaiensis, which had a common ancestor with Drosophila about 510 million years ago. The establishment of the layers of the Parhyale juvenile cuticle is largely governed by mechanisms observed in Drosophila, e.g. as in Drosophila, the synthesis and arrangement of chitin in the inner procuticle are separate processes. A major difference between the cuticle of Parhyale and Drosophila concerns the restructuring of the Parhyale dorsal epicuticle after deposition. In contrast to the uniform cuticle of the Drosophila larva, the Parhyale cuticle is subdivided into two regions, the ventral and the dorsal cuticles. Remarkably, the boundary between the ventral and dorsal cuticles is sharp suggesting active extracellular regionalisation. The present analysis of Parhyale cuticle differentiation should allow the characterisation of the cuticle-producing and -organising factors of Parhyale (by comparison with the branchiopod crustacean Daphnia pulex) in order to contribute to the elucidation of fundamental questions relevant to extracellular matrix organisation and differentiation.

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
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
In penaeid shrimps, vitellogenin (VTG), the precursor of vitellin, is synthesized in the ovary and hepatopancreas and accumulated in oocytes during ovarian development. In the present study, VTG gene expression levels and hemolymph VTG levels were determined throughout ovarian development in female kuruma prawn, Marsupenaeus japonicus. Hemolymph VTG levels and VTG mRNA levels in the ovary and hepatopancreas were high during vitellogenesis, remained high until final maturation, and then decreased after oviposition. This profile suggests that VTG synthesis activity increases during vitellogenesis and decreases after oviposition. Absence of a significant increase in ovary size in final maturation suggests cessation of yolk accumulation and low activity of VTG synthesis in spite of high VTG mRNA levels. VTG mRNA levels in ovary and hepatopancreas were both highly correlated during vitellogenesis. Thus, their contribution to yolk accumulation seems to be similar. In contrast, VTG mRNA levels in the hepatopancreas increased more slowly at the start of vitellogenesis and declined more sharply after oviposition than in the ovary. This suggests a difference in the regulation of VTG synthesis between the ovary and the hepatopancreas.

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).
