Abstract
BACKGROUND The river prawn, Macrobrachium americanum (M. americanum), is one of the largest prawns of the genus in Latin America and is an amphidromous species distributed along the Pacific coast of America. This prawn has commercial value due to its size and taste, making it a good option for aquaculture production. Its culture has been attempted in ponds and concrete tanks, but no successful technique can still support commercial production. Understanding the mechanisms that regulate reproduction at the molecular level is very important. This knowledge can provide tools for manipulating transcripts, which could increase the number or size of animals in the culture. Our understanding of the mechanism that regulates the reproduction of M. americanum at the molecular level is limited. AIM Perform and analyze the transcriptome assembly of the testes, vas deferens, and terminal ampulla of M. americanum. to provide new molecular information about its reproduction. METHODS AND RESULTS The cDNA library was constructed and sequenced for each tissue to identify novel transcripts. A combined transcriptome with the three tissues was assembled using Trinity software. Unigenes were annotated using BLASTx and BLAST2GO. The transcriptome assembly generated 1,059,447 unigenes, of which 7222 genes had significant hits (e-value < 1 × 10-5) when compared against the Swiss-Prot database. Around 75 genes were related to sex determination, testis development, spermatogenesis, spermiogenesis, fertilization, maturation of testicular cells, neuropeptides, hormones, hormone receptors, and/or embryogenesis. CONCLUSIONS These results provide new molecular information about M. americanum reproduction, representing a reference point for further genetic studies of this species.

[PMID: 37510358 PMCID: PMC10380074 DOI: 10.3390/genes14071454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 07/13/2023] [Accepted: 07/14/2023] [Indexed: 07/30/2023] Open
Abstract
XRN1 is an exoribonuclease that degrades mRNA in the cytoplasm along the 5'-3' direction. A previous study indicated that it may be involved in the reproduction of Macrobrachium nipponense. Quantitative real-time PCR was used to detect the spatiotemporal expression pattern of Mn-XRN1. At the tissue level, Mn-XRN1 was significantly expressed in the ovary. During development, Mn-XRN1 was significantly expressed at the CS stage of the embryo, on the 10th day post-larval and in the O2 stage of ovarian reproduction. The in situ hybridization results showed the location of Mn-XRN1 in the ovary. The expression of Mn-VASA was significantly increased after in vivo injection of Mn-XRN1 dsRNA. This suggests that Mn-XRN1 negatively regulates the expression of Mn-VASA. Furthermore, we counted the number of M. nipponense at various stages of ovarian reproduction on different days after RNAi. The results showed that ovarian development was significantly accelerated. In general, the results of the present study indicate that Mn-XRN1 has an inhibitory effect on the ovarian maturation of M. nipponense. The inhibitory effect might be through negative regulation of Mn-VASA.

Identification and characterization of a new germline-specific marker vasa gene and its promoter in the giant freshwater prawn Macrobrachium rosenbergii. Comp Biochem Physiol B Biochem Mol Biol 2022; 259:110716.

Abstract
Vasa gene encodes a protein member of DEAD-box superfamily of ATP-dependent RNA helicases, which plays a key role in germline development in metazoans. In present study, we identified a new germline-specific marker Mrvasa in the prawn Macrobrachium rosenbergii, whose genomic DNA sequence consists of 14 exons and 13 introns. A 2516 bp of full-length Mrvasa cDNA encodes a protein of 603 amino acids. It contains nine conserved motifs, a zinc-finger motif, and RGG repeats. RT-PCR indicated that Mrvasa mRNA was specifically expressed in gonads. QPCR analysis further revealed that the expression of Mrvasa mRNA is much higher in testis than in ovary. In testis, the relative expression level of Mrvasa mRNA in late developing stage is significantly higher than that in early-middle developing stage. During ovarian development, no significant difference in expression was found. In situ hybridization demonstrated that Mrvasa mRNA was localized in germline cells including spermatogonia, spermatocytes, and spermatozoa in testes, and previtellogenic and vitellogenic oocytes in ovary. We then isolated the Mrvasa promoter and determined the transcription core region of this promoter. This is the first report on identification of vasa core promoter in crustaceans. Our results will provide a useful germline-specific marker Mrvasa for tracing germline cell formation and development in M. rosenbergii.

Abstract
Cadmium (Cd), a widespread, severely toxic heavy metal, can cause serious reproductive toxicity in animals. However, the molecular pathways associated with Cd-induced effects remain unknown. In this study, we first cloned the vasa gene (Shvasa) and characterized the VASA protein (ShVASA) in Sinopotamon henanense. We then investigated the molecular mechanisms of Cd-induced reproductive toxicity. Shvasa was specifically expressed in the ovary and testis. ShVASA was abundant in early ovarian development and significantly less abundant in mature ovaries. During oogenesis, ShVASA was abundant and evenly distributed in the cytoplasm of the oogonium and previtellogenic oocytes, but gradually accumulated in the nuclear periphery of vitellogenic and mature oocytes. As Cd concentration increased, ShVASA abundance decreased gradually in proliferation-stage ovaries, and increased gradually in mature ovaries. Notably, at the small and large growth stages, ShVASA was upregulated following exposure to 14.5 mg/L Cd and downregulated following exposure to 29 mg/L Cd. In contrast to the unexposed control, ShVASA accumulated around the nuclear periphery in Cd-exposed previtellogenic oocytes and scattered gradually into the cytoplasm in Cd-exposed vitellogenic and mature oocytes. Shvasa RNA interference (RNAi) downregulated Shnanos and Shpiwi, but simultaneous Cd exposure and Shvasa RNAi significantly upregulated Shnanos and downregulated Shpiwi. These data suggested that Cd disrupted Shvasa expression and function, as well as the functions of Shnanos and Shpiwi, leading to severe reproductive toxicity in S. henanense.

Abstract
Germ plasm is a special cytoplasmic component containing special RNAs and proteins, and is located in specific regions of oocytes and embryos. Only the blastomeres inheriting the germ plasm can develop into primordial germ cells (PGCs). By using Vasa mRNA as a germline marker, we previously demonstrated that germline specification followed the preformation mode in the prawn Macrobrachium nipponense. In this study, we raised the Vasa antibody to identify germ plasm in the oocyte and trace the origin and migration of PGCs. In previtellogenic oocytes, Vasa protein was detected in the perinuclear region, in which electron-dense granules associated with numerous mitochondria were mostly visualized under a transmission electron microscope. In mature oocytes, immunosignal was localized to a large granule under the plasma membrane. During early embryogenesis, the granule was inherited by a single blastomere from 1-cell to 16-cell stages, and thereafter was segregated into two daughter blastomeres at the 32-cell stage. In gastrula, the Vasa-positive cells were large with typical PGC characteristics, containing a big round nucleus and a prominent nucleolus. The immunosignal was localized to the perinuclear region again. In the zoea stage, the Vasa-positive cells migrated toward the genital ridge and clustered in the dorsomedial region close to the yolk portion. Accordingly, we concluded that the prawn PGCs could be specified from the 16-cell stage by inheriting the germplasm. To our knowledge, this is the first report on the identification of the prawn germ plasm and PGCs. The continuous expression of Vasa protein throughout oogenesis and embryogenesis suggests that Vasa protein could be an important factor in germ plasm that functions in early germ cell specification.

Abstract
Germ cell-specific genes play an important role in establishing the reproductive system in sexual organisms and have been used as valuable markers for studying gametogenesis and sex differentiation. Previously, we isolated a vasa transcript as a germ cell marker to trace the origin and migration of germ cells in the oriental river prawn Macrobrachium nipponense. Here, we identified a new germ cell-specific marker MnTdrd RNA and assessed its temporal and spatial expression during oogenesis and embryogenesis. MnTdrd transcripts were expressed in high abundance in unfertilized eggs and embryos at cleavage stage and then dropped significantly during late embryogenesis, suggesting that MnTdrd mRNA is maternally inherited. In situ hybridization of ovarian tissue showed that MnTdrd mRNA was initially present in the cytoplasm of previtellogenic oocyte and localized to the perinuclear region as the accumulation of yolk in vitellogenic oocyte. Whole-mount in situ hybridization of embryos showed that MnTdrd-positive signals were only localized in one blastomere until 16-cell stage. In the blastula, there were approximately 16 MnTdrd-positive blastomeres. During embryonized-zoea stage, the MnTdrd-positive cells aggregated as a cluster and migrated to the genital rudiment which would develop into primordial germ cells (PGCs). The localized expression pattern of MnTdrd transcripts resembled that of the previously identified germ cell marker vasa, supporting the preformation mode of germ cell specification. Therefore, we concluded that MnTdrd, together with vasa, is a component of the germ plasm and might have critical roles in germ cell formation and differentiation in the prawn. Thus, MnTdrd can be used as a novel germ cell marker to trace the origin and migration of germ cells.

Alternative splice variants and differential relative abundance patterns of vasa mRNAs during gonadal development in the Chinese mitten crab Eriocheir sinensis. Anim Reprod Sci 2019; 208:106131. [PMID: 31405476 DOI: 10.1016/j.anireprosci.2019.106131] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 06/19/2019] [Accepted: 07/17/2019] [Indexed: 11/29/2022]
Abstract
Gonadal development usually involves alternative splicing of sex-related genes. Vasa, a highly conserved ATP-dependent RNA helicase present mainly in germ cells, has an important function in gonadal development. As an important sex-related gene, recent evidence indicates that different splice variants of vasa exist in many species. In this study, there was identification of two types of vasa splice variants in the Chinese mitten crab Eriocheir sinensis, termed Esvasa-l and Esvasa-s, respectively. Furthermore, splice variants of Esvasa-s were sub-divided into Esvasa-s1, Esvasa-s2, Esvasa-s3, Esvasa-s4, and Esvasa-s5, based on differing numbers of TGG repeats. Results from genomic structure analyses indicated that these forms are alternatively spliced transcripts from a single vasa gene. Results from tissue distribution assessments indicate the vasa splice variants were exclusively expressed in the gonads of male and female adult crabs. In situ hybridization results indicate Esvasa mRNA was mainly present in the cytoplasm of previtellogenic oocytes. As oocyte size increased, relative abundance of Esvasa mRNA decreased and became distributed near the cellular membrane. The Esvasa mRNA was not detectable in mature oocytes. In testis, Esvasa mRNA was detected in spermatids and spermatozoa, but not in spermatogonia and spermatocytes. Notably, results from qPCR analysis of Esvasa-l and Esvasa-s indicate there are different relative proportions during gametogenesis, implying that splice variants of the Esvasa gene may have different biological functions during crab gonadal development.

Abstract
Luteinizing hormone (LH), a pituitary gonadotropin, coupled with LH receptor (LHR) is essential for the regulation of the gonadal maturation in vertebrates. Although LH homolog has been detected by immunocytochemical analysis, and its possible role in ovarian maturation was revealed in decapod crustacean, so far there is no molecular evidence for the existence of LHR. In this study, we cloned a novel LHR homolog (named EsLHR) from the Chinese mitten crab Eriocheir sinensis. The complete sequence of the EsLHR cDNA was 2775bp, encoding a protein of 924 amino acids, sharing 71% amino acids identity with the ant Zootermopsis nevadensis LHR. EsLHR expression was found to be high in the ovary, while low in testis, gill, brain, and heart, and no expression in the thoracic ganglion, eye stalk, muscle, and hepatopancreas. Quantitative PCR revealed that the expression level of EsLHR mRNA was significantly higher in the ovaries in previtellogenic (Pvt), late vitellogenic (Lvt), and germinal vesicle breakdown (GVBD) stages than that in the vitellogenic (Mvt) and early vitellogenic (Evt) stages (P < 0.05), and, the highest and the lowest expression were in Lvt, and Evt, respectively. The strong signal was mainly localized in the ooplasm of Pvt oocyte as detected by in situ hybridization. The crab GnRH homolog can significantly induce the expression of EsLHR mRNA at 36 hours post injection in vivo (P < 0.01), suggesting that EsLHR may be involved in regulating ovarian development through GnRH signaling pathway in the mitten crab.
