Immune gene expression and antioxidant response to vitamin E enriched diets for males Litopenaeus vannamei breeder (Boone, 1931). Comp Biochem Physiol A Mol Integr Physiol 2022; 268:111187. [PMID: 35301121 DOI: 10.1016/j.cbpa.2022.111187] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 03/10/2022] [Accepted: 03/11/2022] [Indexed: 11/27/2022]
Abstract
The is aim of this study was to evaluate if vitamin E supplementation to diet could improve the spermatic quantity and quality in males of Litopenaeus vannamei. A basal diet with 171.5 mg/kg (included in commercial vitamin premix) and experimental diets with 3 concentrations of vitamin E: 620 (diet A), 1069 (diet B) and 1517 (diet C) mg/kg were tested by 30 days. 500 L tanks were set up for each treatment, and seven males were set in each tank. Circulant cholesterol, triglyceride (TG), glucose, total protein was measured. Sperm quantity and quality were classified as normal, abnormal, or dead. In reproductive tract was measured the activity and differential expression lipid soluble antioxidant system (LSAS) and of immune genes system. The higher sperm quantity was obtained in A diet and decreased in shrimp fed B and C diets (p < 0.05). Males fed diets B and C presented a higher activity and relative expression of lipid system oy suggesting oxidative stress. A significant increment of prophenol oxidase (proFo) and α-2-macroglobulin (α-2 M) transcripts were observed in males fed C diet (p < 0.05). All these variables were present in males with low sperm amount and low hemocyanin gene expression (p < 0.05). Therefore, diet A supplemented with 620 mg/kg vitamin E could benefit males L. vannamei broodstock, taking a count the sperm quantity and all the lipid and immune genes response.

Abstract
Male sex differentiation in the crustacean is best known to be controlled by the insulin-like androgenic gland hormone (IAG). In this report, the cDNA and gene of the shrimp Fenneropenaeus merguiensis FmIAG were studied and characterized. FmIAG gene shares a high sequence identity in the coding region as well as the promoter region with that of F. chinensis. FmIAG gene is most likely consists of 5 exons and 4 introns. The cDNA reported here is the most abundant transcript that retained cryptic intron 4. The use of different splicing acceptor sites in exon 2 can produce a long-form FmIAG transcript variant with 6 additional amino acids inserted. Splicing of cryptic intron 4 would produce a transcript variant with a different C-terminal end. Therefore 4 different FmIAG transcripts can be produced from the FmIAG gene. During the molt cycle, the expression level of FmIAG was low in the early intermolt, increase steadily towards the late premolt and decreased rapidly in the early postmolt. In addition to the androgenic gland, FmIAG is also expressed in the hepatopancreas and ovary of adult females. Unilateral eyestalk ablation caused a significant increase in FmIAG transcript suggesting that the eyestalk consists of inhibiting factor(s) that suppressesFmIAGexpression. To explore the function of FmIAG in males, injection of FmIAG dsRNA knock-down the expression of FmIAG and up-regulated the expression of the vitellogenin gene in the testis and hepatopancreas. Interestingly a CHH-like gene identified in the androgenic gland was down-regulated. CHH-like gene knock-down resulted in altered expression of FmIAG in males suggesting that the CHH-like may be involved in FmIAG's regulation. RT-PCR with specific primers to the different transcript variant were used to determine if there is an association of different sizes of male and the type of IAG transcript. Results indicated that a high percentage of the large male shrimp expressed the long-form of FmIAG. The results suggested that FmIAG may be useful as a size marker for male shrimp aquaculture. In summary, the results of this study have expanded our knowledge of shrimp insulin-like androgenic gland hormone in male sex development and its potential role as a marker gene for growth regulation in shrimp.

Use of sperm DNA integrity as a marker for exposure to contamination in Palaemon serratus (Pennant 1777): Intrinsic variability, baseline level and in situ deployment. WATER RESEARCH 2018; 132:124-134. [PMID: 29324292 DOI: 10.1016/j.watres.2017.12.057] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2017] [Revised: 11/22/2017] [Accepted: 12/22/2017] [Indexed: 06/07/2023]
Abstract
In a previous study, the Comet assay was optimized for Palaemon serratus prawns in order to propose a biomarker for sperm quality in this species. However, better knowledge of its basal level and its natural variability, related to intrinsic biotic and environmental abiotic factors, is required before any relevant use of this biomarker in the field. To fulfill this goal, the present study proceeded in three steps: (i) the temporal variability of DNA integrity was followed monthly in a reference population over a 2-year period, (ii) the correlation between the main intrinsic biotic (i.e. size, weight and molting stage) and abiotic factors (i.e. water temperature) were recorded in the field, and the basal DNA integrity was assessed in order to scrutinize any confounding influence of factors unrelated to toxic response, (iii) the baseline level was used to discriminate biomarker response among different stations displaying contrasting contamination levels. The results of the two-year monitoring in the reference population revealed no correlation between the levels of spermatozoa DNA damage and temperature, body size, weight or molting stage. Only a slight variability between monthly samplings was detected. On the basis of these field-collected data, we defined a reference distribution (i.e. 52.6 ± 5.6 A.U) with a threshold value (i.e. 61.7 A.U). Finally, this threshold value proved its relevance to discriminate among stations with contrasting pollution levels around the Seine Bay. Indeed, the results suggest significant DNA damage in populations nearest the Seine estuary, a major source of contaminants in the Bay, and a lower effect in populations further away from the estuary. The overall conclusion was that the Comet assay on P. serratus spermatozoa could be a useful tool for the monitoring of the toxicological print within sperm and main globally the contamination exposure of crustaceans in marine waters.

Differential regulation of hepatopancreatic vitellogenin (VTG) gene expression by two putative molt-inhibiting hormones (MIH1/2) in Pacific white shrimp (Litopenaeus vannamei). Peptides 2015; 68:58-63. [PMID: 25447412 DOI: 10.1016/j.peptides.2014.11.002] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2014] [Revised: 11/04/2014] [Accepted: 11/04/2014] [Indexed: 11/25/2022]
Abstract
Molt-inhibiting hormone (MIH), a peptide member of the crustacean hyperglycemic hormone (CHH) family, is commonly considered as a negative regulator during the molt cycle in crustaceans. Phylogenetic analysis of CHH family peptides in penaeidae shrimps suggested that there is no significant differentiation between MIH and vitellogenesis-inhibiting hormone (VIH, another peptide member of CHH family), by far the most potent negative regulator of crustacean vitellogenesis known. Thus, MIH may also play a role in regulating vitellogenesis. In this study, two previously reported putative MIHs (LivMIH1 and LivMIH2) in the Pacific white shrimp (Litopenaeus vannamei) were expressed in Escherichia coli, purified by immobilized metal ion affinity chromatography (IMAC) and further confirmed by western blot. Regulation of vitellogenin (VTG) mRNA expression by recombinant LivMIH1 and LivMIH2 challenge was performed by both in vitro hepatopancreatic primary cells culture and in vivo injection approaches. In in vitro primary culture of shrimp hepatopancreatic cells, only LivMIH2 but not LivMIH1 administration could improve the mRNA expression of VTG. In in vivo injection experiments, similarly, only LivMIH2 but not LivMIH1 could stimulate hepatopancreatic VTG gene expression and induce ovary maturation. Our study may provide evidence for one isoform of MIH (MIH2 in L. vannamei) may serve as one of the mediators of the physiological progress of molting and vitellogenesis. Our study may also give new insight in CHH family peptides regulating reproduction in crustaceans, in particular penaeidae shrimps.

Abstract
Because of their ecological importance, amphipod crustacea are employed worldwide as test species in environmental risk assessment. Although proteomics allows new insights into the molecular mechanisms related to the stress response, such investigations are rare for these organisms because of the lack of comprehensive protein sequence databases. Here, we propose a proteogenomic approach for identifying specific proteins of the freshwater amphipod Gammarus fossarum, a keystone species in European freshwater ecosystems. After deep RNA sequencing, we created a comprehensive ORF database. We identified and annotated the most relevant proteins detected through a shotgun tandem mass spectrometry analysis carried out on the proteomes from three major tissues involved in the organism's reproductive function: the male and female reproductive systems, and the cephalon, where different neuroendocrine glands are present. The 1,873 mass-spectrometry-certified proteins represent the largest crustacean proteomic resource to date, with 218 proteins being lineage specific. Comparative proteomics between the male and female reproductive systems indicated key proteins with strong sexual dimorphism. Protein expression profiles during spermatogenesis at seven different stages highlighted the major gammarid proteins involved in the different facets of reproduction.

Abstract
Cellular proteomic analysis was carried out to identify reproduction-related proteins in testes of wild and domesticated broodstock of Penaeus monodon. In total, 642 protein spots were characterized and 287 spots (44.70%) significantly matched protein sequences in the databases (P<0.05). To examine a role of the proteasome system in testicular development of P. monodon, the expression profiles of proteasome alpha 3 subunit (PmPsma3) and proteasome beta 6 (PmPsmb6) mRNA in different groups of domesticated shrimp and in wild broodstock were examined. The expression levels of these transcripts in testes of 18-month-old domesticated shrimp were significantly lower than those of wild broodstock (P<0.05). Interestingly, the expression levels of testicular PmPsma3 and PmPsmb6 in 18-month-old shrimp were significantly increased at 24 h following serotonin injection (50 μg/g body weight). Results suggested that reduced degrees of maturation in captive P. monodon males may be partially resolved by exogenous 5-HT administration.

Abstract
Isolation and characterization of genes involving gonadal development are an initial step towards understanding reproductive maturation and sex determination of the giant tiger shrimp (Penaeus monodon). In the present study, 896 clones from the testis cDNA library were sequenced. A total of 606 ESTs (67.6%) significantly matched sequences in the GenBank (E-value <1e-04) whereas 290 ESTs (32.4%) were newly unidentified transcripts. The full length cDNA of genes functionally involved in testicular development including cyclophilin A (PMCYA), small ubiquitin-like modifier 1 (PMSUMO-1), ubiquitin conjugating enzyme E2, dynactin subunit 5, cell division cycle 2 (cdc2) and mitotic checkpoint BUB3 were discovered. In addition, Tra-2, a gene involving sex determination cascades, was successfully characterized by RACE-PCR and first reported in crustaceans. Expression analysis indicated that a homologue of low molecular weight neurofilament protein XNF-L (termed P. monodon testis-specific transcript 1, PMTST1; N=8 for each sex) was only expressed in testes but not ovaries. PMCYA, thyroid hormone receptor-associated protein complex 240 kDa component (Trap240), multiple inositol polyphosphate phosphatase 2 (MIPP2) and heat shock-related 70 kDa protein 2 (HSP70-2), but not PMSUMO-1, PMTra-2 and prohibitin2 were differentially expressed between ovaries and testes of P. monodon. Expression of PMTST1 was up-regulated but that of the remaining genes in testes of P. monodon broodstock was down-regulated after shrimp were molted (P<0.05). Significant reduction of PMSUMO-1 and increment of prohibitin2 transcripts in domesticated broodstock (P<0.05) suggested that these reproductively related genes may be used as biomarkers to evaluate reduced degrees of the reproductive maturation in domesticated P. monodon.
