Abstract
Cellular proteomics of total proteins in ovaries of domesticated and wild giant tiger shrimp (Penaeus monodon) were examined using GeLC-MS/MS. In total, 1638 proteins matched those previously deposited in databases and 1253 (76.50%) of these significantly matched known proteins. Several reproduction-related proteins (e.g. Cdc2, Cyclin B, Cdc25, 14-3-3, thymosin-β and Rac-GTPase activating protein 1) were identified. In addition, the full-length cDNA of P. monodon thymosin-β (PmTmsb; 1084 bp with an ORF of 387 bp and 128 deduced aa) and Rac-GTPase activating protein 1 (PmRacgap1; an ORF of 1881 bp and 626 deduced aa) were further characterized. PmTmsb was constitutively expressed in all tissues. In contrast, PmRacgap1 was more abundantly expressed in gonads than in several non-reproductive tissues (e.g. subcuticular epithelium, hepatopancreas, intestine, pleopods, stomach and thoracic ganglion). The expression levels of PmTmsb and PmRacgap1 in ovaries of wild adult broodstock were significantly greater than those in ovaries of juveniles (P<0.05). However, their expression levels did not vary significantly during ovarian development stages in intact broodstock. However, eyestalk ablation resulted in a significant reduction in PmTmsb expression at stages I and III ovaries (P<0.05), although it did not affect PmRacgap1 transcription significantly at these stages. On the other hand, use of polyclonal antibodies derived from recombinant PmTmsb and PmRacgap1 revealed that levels of both proteins decreased at the late stage (IV) of ovarian development. Our results suggested that PmTmsb and PmRacgap1 may act as negative effectors during ovarian development in P. monodon.

[PMID: 24095778 DOI: 10.1016/j.gene.2013.09.089] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2013] [Revised: 09/23/2013] [Accepted: 09/24/2013] [Indexed: 11/30/2022]
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.

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
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.

Abstract
Knowledge on molecular mechanisms of steroid hormonal induction on oocyte development may lead to the possible ways to effectively induce ovarian maturation in shrimp. In this study, progestin membrane receptor component 1 (Pgmrc1) of the giant tiger shrimp (Penaeus monodon) initially identified by EST analysis was further characterized. The full-length cDNA of Pgmrc1 was 2015bp in length containing an ORF of 573bp corresponding to a polypeptide of 190 amino acids. Northern blot analysis revealed a single form of Pgmrc1 in ovaries of P. monodon. Quantitative real-time PCR indicated that the expression level of Pgmrc1 mRNA in ovaries of both intact and eyestalk-ablated broodstock was greater than that of juveniles (P<0.05). Pgmrc1 was up-regulated in mature (stage IV) ovaries of intact broodstock (P<0.05). Unilateral eyestalk ablation resulted in an earlier up-regulation of Pgmrc1 since the vitellogenic (II) ovarian stage. Moreover, the expression level of Pgmrc1 in vitellogenic, early cortical rod and mature (II-IV) ovaries of eyestalk-ablated broodstock was greater than that of the same ovarian stages in intact broodstock (P<0.05). Pgmrc1 mRNA was clearly localized in the cytoplasm of follicular cells, previtellogenic and early vitellogenic oocytes. Immunohistochemistry revealed the positive signals of the Pgmrc1 protein in the follicular layers and cell membrane of follicular cells and various stages of oocytes. Taken the information together, Pgmrc1 gene products seem to play the important role on ovarian development and may be used as the bioindicator for monitoring progression of oocyte maturation of P. monodon.

Abstract
The meiotic maturation of oocytes is regulated by maturation promoting factor (MPF), a complex of cdc2 (Cdk1) and cyclin B and other Cdk/cyclin complexes. To better understand molecular aspects governing reproductive maturation of the giant tiger shrimp (Penaeus monodon), the full length cDNAs and genomic organization of cyclins A and B (PMCyA and PMCyB) were characterized. A single form of PMCyA contained an open reading frame (ORF) of 1326 bp corresponding to a deduced protein of 441 amino acids. Its genomic sequence contained 5 exons, 4 introns and untranslated regions (UTRs) spanning 2586 bp in length. In contrast, PMCyB possessed three isoforms with an identical ORF of 1206 bp (401 amino acids) but three different 3' UTR lengths of 416, 543 and 1117 bp, respectively. Their respective genomic sequences were composed of 8 exons, 7 introns and UTRs covering 4181, 4307 and 4940 bp. Expression levels of both PMCyA and PMCyB in ovaries of broodstock were much greater than those of juveniles (P<0.05). During ovarian development and after spawning of normal shrimp broodstock, PMCyA was not differentially expressed (P>0.05) whereas the level of PMCyB in stage IV was greater than that of stage I ovaries (P<0.05). Unilateral eyestalk ablation, a technique commonly used to induce spawning in P. monodon female brooders, had no effects on transcription of PMCyB (P>0.05) but resulted in a lower expression of PMCyA at stage IV of ovarian development of this economically important species (P<0.05).

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

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

Abstract
Vitellin (Vt) was purified from ovary extracts of mature females of the banana shrimp Litopenaeus merguiensis using DEAE-Sephacel and Superdex 200 columns. Native Vt had an apparent molecular mass of 398 kDa as determined by native PAGE and by gel filtration chromatography. Under reducing and denaturing conditions (SDS-PAGE), Vt is composed of two major subunits of 87 and 78 kDa, although some faint bands were also detected. The N-terminal 10 amino acids sequence of the 78 kDa subunit is identical to that of Litopenaeus vannamei Vt and very similar to that of Litopenaeus japonicus vitellogenin (Vg) as well as Litopenaeus semisulcatus Vt, with an identity of 89%. Anti-Vt polyclonal antibody raised against purified Vt shows a high specificity with only ovarian Vt and hemolymph Vg of vitellogenic shrimps in double immunodiffusion and Western blot assays. Vg and Vt concentrations in hemolymph, hepatopancreas and ovaries were measured by ELISA. Vg concentrations increased in the hemolymph in the early stages of ovarian development and declined in the maturation stages. As there were undetectable concentrations of Vg in the hepatopancreas while an elevation of Vg levels occurred in the hemolymph, during the time that Vt was accumulating in the ovaries during oogenesis, this would suggest that the contribution of Vg synthesized by the hepatopancreas only might be not sufficient for adequate development of the oocytes in the banana shrimp L. merguiensis during vitellogenesis.

Abstract
Two cDNA clones (634 and 1366 bp) encoding MIH/VIH (molt-inhibiting hormone/vitellogenesis-inhibiting hormone)-related peptides were isolated and sequenced from a Macrobrachium rosenbergii eyestalk ganglia cDNA library. The clones contain a 360 and 339 bp open-reading frame, and their conceptually translated peptides consist of a 41 and 34 amino acid signal peptide, respectively, and a 78 amino acid residue mature peptide hormone. The amino acid sequences of the peptides exhibit higher identities with other known MIHs and VIH (44-69%) than with CHHs (28-33%). This is the first report describing the cloning and sequencing of two MIH/VIH-related peptides in a single crustacean species. Transcription of these mRNAs was detected in the eyestalk ganglia, but not in the thoracic ganglia, hepatopancreas, gut, gill, heart, or muscle.
