Abstract
The survival of a species largely depends on the ability of individuals to reproduce, thus perpetuating their life history. The advent of metazoans (i.e. pluricellular animals) brought about the evolution of specialized tissues and organs, which in turn led to the development of complex protein regulatory pathways. This study sought to elucidate the evolutionary relationships between female reproduction-associated proteins by analyzing the transcriptomes of representative species from a selection of marine invertebrate phyla. Our study identified more than 50 reproduction-related genes across a wide evolutionary spectrum, from Porifera to Vertebrata. Among these, a total of 19 sequences had not been previously reported in at least one phylum, particularly in Porifera. Moreover, most of the structural differences between these proteins did not appear to be determined by environmental pressures or reproductive strategies, but largely obeyed a distinguishable evolutionary pattern from sponges to mammals.

Transcriptome analyses reveal the synergistic effects of feeding and eyestalk ablation on ovarian maturation in black tiger shrimp. Sci Rep 2020; 10:3239. [PMID: 32094422 PMCID: PMC7040003 DOI: 10.1038/s41598-020-60192-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Accepted: 02/03/2020] [Indexed: 01/23/2023] Open
Abstract
Unilateral eyestalk ablation in the female black tiger shrimp Penaeus monodon is commonly employed to induce ovarian maturation. However, the importance of complementing this practice with the provision of live feed supplement (such as polychaetes) has not been emphasized in previous studies. Indeed, it has been less emphasized that female broodstock must be fed with live feeds such as polychaetes for this practice to be effective. While the effects of eyestalk ablation have been thoroughly studied in various aspects, the synergistic effects of feeding with live feeds and the ablation have never been elucidated at a transcriptome-wide level. With recent advances in the next-generation sequencing platforms, it is now possible to investigate the effects of eyestalk ablation and live feeds at the transcriptomic levels. This study employed both short-read Illumina RNA sequencing and long-read Pacific Biosciences (PacBio) isoform sequencing (Iso-seq) to generate the first high-quality ovarian reference transcriptome in P. monodon. This novel assembly allowed us to dissect the effects of feeds and eyestalk ablation and reveal their synergistic effects at the transcriptomic level through the regulation of important genes involved in fatty acid regulation, energy production, and hormone-mediated oocyte maturation pathways. The synergistic effects between the polychaete feeding and the eyestalk ablation in the process of ovarian maturation in black tiger shrimp suggest that without having proper nutrients from the polychaetes, female broodstock might not be ready to develop its ovary. However, even with proper nutrients, the eyestalk ablation is still necessary to perhaps manipulate the female endocrine of the black tiger shrimp. These findings shed the light on molecular mechanisms and key molecular pathways that lead to successful ovarian maturation.

BMC Genomics 2019; 20:757. [PMID: 31640556 PMCID: PMC6805652 DOI: 10.1186/s12864-019-6157-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Accepted: 10/09/2019] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND The common littoral shrimp Palaemon serratus is an economically important decapod resource in some European communities. Aquaculture practices prevent the genetic deterioration of wild stocks caused by overfishing and at the same time enhance the production. The biotechnological manipulation of sex-related genes has the proved potential to improve the aquaculture production but the scarcity of genomic data about P. serratus hinders these applications. RNA-Seq analysis has been performed on ovary and testis samples to generate a reference gonadal transcriptome. Differential expression analyses were conducted between three ovary and three testis samples sequenced by Illumina HiSeq 4000 PE100 to reveal sex-related genes with sex-biased or sex-specific expression patterns. RESULTS A total of 224.5 and 281.1 million paired-end reads were produced from ovary and testis samples, respectively. De novo assembly of ovary and testis trimmed reads yielded a transcriptome with 39,186 transcripts. The 29.57% of the transcriptome retrieved at least one annotation and 11,087 differentially expressed genes (DEGs) were detected between ovary and testis replicates. Six thousand two hundred seven genes were up-regulated in ovaries meanwhile 4880 genes were up-regulated in testes. Candidate genes to be involved in sexual development and gonadal development processes were retrieved from the transcriptome. These sex-related genes were discussed taking into account whether they were up-regulated in ovary, up-regulated in testis or not differentially expressed between gonads and in the framework of previous findings in other crustacean species. CONCLUSIONS This is the first transcriptome analysis of P. serratus gonads using RNA-Seq technology. Interesting findings about sex-related genes from an evolutionary perspective (such as Dmrt1) and for putative future aquaculture applications (Iag or vitellogenesis genes) are reported here. We provide a valuable dataset that will facilitate further research into the reproductive biology of this shrimp.

Abstract
In aquaculture practices, prawn cultivation holds the major share and Penaeus monodon is the main species cultured. The decline in production of P. monodon is mainly due to the limited availability of domesticated broodstock, which is attributed to its reproductive cycle, controlled by complex coordinated signaling mechanisms. Unilateral eyestalk ablation of domesticated females held in captivity is done to induce ovary development, which has certain disadvantages, including a high rate of mortality. Thus, developing alternative techniques for eyestalk ablation in captive broodstock is necessary to induce maturation of ovary. This study exemplifies the role of 5HT along with a cocktail of inhibitors (U0126, Rp-cAMP, and LY294002) in inducing ovarian maturation. In this study, inhibition of pERK by U0126 inhibited vitellogenesis-inhibiting hormone (VIH), which in turn led to the overexpression of vitellogenin. 5HT induces steroidogenesis (estradiol-17β) through induction of the gonadotropin-releasing hormone by activating calcium-calmodulin signaling. Steroidogenesis is also aided by synthesis of StAR protein. Estradiol-17β stimulates the formation of the maturation-promoting factor (MPF) complex by cdc25 activation and Myt1 inactivation. LY294002 aids in keeping cdc25 activated by inhibiting calcium-calmodulin induced phosphorylation of Akt which is a negative regulator of mitogen-activated protein kinases. VIH induced activation of Myt1, through protein kinase A (PKA), was inhibited by Rp-cAMP which inhibits adenylate cyclase, thus stabilizing the activated MPF complex. To conclude, the coordinated effect of inhibitors and 5HT accelerates the development of ovary from previtellogenic to matured oocytes, yielding high quality and quantity larvae compared with eyestalk-ablated P. monodon.

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
The banana shrimp (Fenneropenaeus merguiensis) is one of the most commercially important penaeid species in the world. Its numbers are declining in the wild, leading to a loss of broodstock for farmers of the shrimp and a need for more successful breeding programs. However, the molecular mechanism of the genes involved in this shrimp’s ovarian maturation is still unclear. Consequently, we compared transcriptomic profiles of ovarian tissue from females in both the vitellogenic stage and the non-vitellogenic stage. Using RNA-Seq technology to prepare the transcriptome libraries, a total of 12,187,412 and 11,694,326 sequencing reads were acquired from the non-vitellogenic and vitellogenic stages respectively. The analysis of the differentially expressed genes identified 1,025 which were significantly differentially expressed between the two stages, of which 694 were up-regulated and 331 down-regulated. Four genes putatively involved in the ovarian maturation pathway were chosen for validation by quantitative real-time PCR (RT-qPCR). The data from this study provided information about gene expression in ovarian tissue of the banana shrimp which could be useful for a better understanding of the regulation of this species’ reproductive cycle.

Abstract
Background The green mud crab (Scylla paramamosain) is the most prevalent crustacean on the southeast coast of China. The molecular regulatory mechanism of sex determination and gonadal differentiation in this species has received considerable attention in recent years because of the huge differences—both biological and economic—between male and female crabs. In this study, next-generation sequencing technology was used to develop deep-coverage transcriptomic sequencing data for the testis and ovary of S. paramamosain. Results A total of 365,116 reads (testis 171,962, ovary 193,154) with an average sequence length of 285 bp were produced from testis and ovary cDNA libraries. After filtering out contaminating reads, the clean reads were assembled, producing a total of 21,791 isotigs and leaving 22,814 reads as singlets. Using the BLASTX program, 3,471 unique sequences (2,275 isotigs and 1,196 singletons) were annotated with known protein sequences from the NCBI non-redundant (Nr) protein sequence database. The Gene Ontology and KEGG (Kyoto Encyclopedia of Genes and Genomes) analyses allowed the 224 unique sequences that were annotated with enzyme code (EC) numbers to be mapped into 174 KEGG pathways. After comparing the ovary and testis libraries, 4,021 gonad-differentially, 10,522 ovary-specifically, and 19,013 testis-specifically expressed genes were identified. Moreover, 33 ovary-specific, 14 testis-specific, and 34 gonad-differential transcripts were confirmed by semi-quantitative PCR and quantitative real-time PCR. In addition, 8,610 putative simple sequence repeats (SSRs) and 23,879 potential single nucleotide polymorphisms (SNPs) were identified. Conclusion This is the first large-scale RNA sequencing of S. paramamosain to be reported. We have identified many important functional genes and made a preliminary attempt to construct the regulatory network involved in the gonadal development of crustaceans. The annotated transcriptome data will provide fundamental support for future research into the reproduction biology of S. paramamosain. A large number of candidate SSRs and SNPs were detected, which could be used as genetic markers for population genetics and functional genomics in this species.

Abstract
Two-dimensional electrophoresis and mass spectrometry were used to identify proteins that are differentially expressed during ovarian maturation in Metapenaeus ensis. 87 spots with consistently significant quantitative differences (≥ 1.5-fold for vol%) among stage I, III and V ovaries were chosen for MS/MS analysis. 45 spots were significantly matched to known proteins in the database (Mascot score >40). Half of them were down-regulated, in contrast to 9 out of 45 proteins that were up-regulated as ovarian maturation proceeded. Functionally, these identified proteins could be classified into five major groups, including cytoskeleton (11 %), metabolism (18 %), signal transduction (32 %), gene expression (14 %) and immune response (7 %). Among the differentially expressed reproduction-related proteins, the mRNA expression level of cellular retinoic acid/retinol binding protein in M. ensis (MeCRABP) during ovarian maturation was further characterized by quantitative real-time PCR. It was down-regulated during ovarian maturation. In situ hybridization further revealed that MeCRABP transcript was localized in ooplasm of previtellogenic oocytes but not in vitellogenic oocytes. These results demonstrate the application of proteomic analysis for identification of proteins involved in shrimp ovarian maturation and they provide new insights into ovarian development.

Abstract
Valosin-containing protein (VCP), a member of the ATPase-associated with diverse cellular activity (AAA) family, was identified from the giant tiger shrimp (Penaeus monodon). The full-length cDNA of the PmVCP mRNA consisted of 2,724 bp containing an ORF of 2,367 bp corresponding to a deduced polypeptide of 788 amino acids. The deduced PmVCP protein contained two putative Cdc48 domains (positions 17-103, E-value=2.00e-36 and 120-186, E-value=3.60e-11) and two putative AAA domains (positions 232-368, E-value=3.67e-24 and 505-644, E-value=3.73e-25). PmVCP mRNA expression in ovaries was greater than that in testes in both juveniles and broodstock. PmVCP was significantly up-regulated in stages II and IV ovaries in intact wild broodstock (P<0.05) but it was not differentially expressed during ovarian development in eyestalk-ablated broodstock (P>0.05). The expression level of PmVCP mRNA in ovaries of 14-month-old shrimp was not affected by progesterone injection (0.1μg/g body weight, P>0.05). In contrast, exogenous 5-HT administration (50μg/g body weight) resulted in an increase of PmVCP mRNA in ovaries of 18-month-old shrimp at 6 and 24h post-injection (hpi) (P<0.05). The rPmCdc48-VCP protein and its polyclonal antibody were successfully produced. Cellular localization revealed that PmVCP was localized in the ooplasm of previtellogenic oocytes. Subsequently, it was translocated into the germinal vesicle of vitellogenic oocytes. Interestingly, PmVCP was found in nucleo-cytoplasmic compartments, in the cytoskeletal architecture and in the plasma membrane of mature oocytes in both intact and eyestalk-ablated broodstock.

Abstract
Proteomic analysis was carried out for identification of proteins functionally involved in ovarian development of the giant tiger shrimp (Penaeus monodon). A total of 335 protein spots including 183 spots from vitellogenic (stage II) and 152 spots from mature (stage IV) ovaries of intact P. monodon broodstock were examined. Of these, 75 (40.98%) and 59 (38.82%) spots significantly matched known proteins in the databases, respectively. In addition, 270 protein spots including 167 and 103 spots from respective ovarian stages of eyestalk-ablated broodstock were also characterized. A total of 95 (56.89%) and 62 (60.19%) spots matched known proteins, respectively. Among differentially expressed reproduction-related proteins, the full-length cDNA of protein disulfide isomerase A6 (PmPDIA6) was further characterized by RACE-PCR. PmPDIA6 was 1946bp in length containing an open reading frame (ORF) of 1293bp corresponding to a polypeptide of 430 amino acids. PmPDIA6 was up-regulated at stage III ovaries in intact shrimp (P<0.05). Interestingly, eyestalk ablation resulted in a lower expression level of PmPDIA6 in each stage of ovarian development compared to that of intact broodstock (P<0.05). Results in this study clearly indicated the potential of cellular proteomic studies and gene expression analysis for identification of proteins/genes differentially expressed during ovarian development of P. monodon.

Insights into eyestalk ablation mechanism to induce ovarian maturation in the black tiger shrimp. PLoS One 2011; 6:e24427.

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

Abstract
Isolation and characterization of genes and/or proteins differentially expressed in ovaries are necessary for understanding ovarian development in the giant tiger shrimp (Penaeus monodon). In this study, the full-length cDNA of P. monodon mitogen-activating protein kinase 1 (PmMAPK1) was characterized. PmMAPK1 was 1,398 bp in length containing an open reading frame of 1,098 bp that corresponded to a polypeptide of 365 amino acids. PmMAPK1 was more abundantly expressed in ovaries than in testes of P. monodon. Quantitative real-time PCR revealed differential expression levels of PmMAPK1 mRNA during ovarian development of intact broodstock, where it peaked in early cortical rod (stage III) ovaries (P < 0.05) and slightly decreased afterwards (P > 0.05). Likewise, the expression level of PmMAPK1 in early cortical rod and mature (IV) ovaries was significantly greater than that in previtellogenic (I) and vitellogenic (II) ovaries of eyestalk-ablated broodstock (P < 0.05). The PmMAPK1 transcript was localized in ooplasm of previtellogenic oocytes. In intact broodstock, the expression of the PmMAPK1 protein was clearly increased from previtellogenic ovaries in subsequent stages of ovarian development (P < 0.05). In contrast, the level of ovarian PmMAPK1 protein was comparable during oogenesis in eyestalk-ablated broodstock (P > 0.05). The PmMAPK1 protein was localized in ooplasm of previtellogenic and vitellogenic oocytes. It was also detected around the nuclear membrane of early cortical rod oocytes in both intact and eyestalk-ablated broodstock. Results indicated that PmMAPK1 gene products seem to play functional roles in the development and maturation of oocytes/ovaries in P. monodon.
