Gene 2024; 927:148682. [PMID: 38876404 DOI: 10.1016/j.gene.2024.148682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 06/04/2024] [Accepted: 06/10/2024] [Indexed: 06/16/2024]
Abstract
The swimming crab, Portunus trituberculatus is one of crucial aquaculture crabs with significant differences in growth and economic performance between male and female swimming crabs. Consequently, the culture of female populations presents higher economic value. The doublesex and mab-3 related transcription factor (Dmrt) gene family are known to play crucial role in gonad differentiation and development. However, there is limited information about this gene family in Portunus trituberculatus. In this study, we identified seven members of the Dmrt gene family in P. trituberculatus based on the published transcriptome and genome data and designated as Ptdmrt-1, Ptdoublesex (Ptdsx), Ptidmrt-1, Ptdmrt-11E, Ptidmrt-2, Ptdmrt-99B, and Ptdmrt-3 based on the homology analysis results, respectively. These Ptdmrt genes distributed across 6 chromosomes and were predicted to encode 283 aa, 288 aa, 529 aa, 436 aa, 523 aa, 224 aa, and 435 aa protein precursors, respectively. The expression patterns of these dmrt genes were characterized by qRT-PCR and gonad transcriptome data. The results showed that five members (Ptdmrt-99B, Ptdsx, Ptdmrt-1, Ptdmrt-3, and Ptdmrt-11E) were differentially expressed between the testis and ovary. In addition, their expression patterns from zoea 2 to juvenile 1 were characterized by published transcriptome data and the results showed that they were lowly expressed and did not exhibit notable difference except for Ptdsx during early development. Overall, majority of Ptdmrt genes were involved in gonad differentiation in the swimming crab. Current findings provide a solid foundation for further exploration of the roles of these genes in gonad development and differentiation in P. trituberculatus.

Identification of COMMD gene family in large yellow croaker (Larimichthys crocea): Immune response induced by Pseudomonas plecoglossicida infection and acute hypoxia stress. FISH & SHELLFISH IMMUNOLOGY 2024; 152:109780. [PMID: 39033968 DOI: 10.1016/j.fsi.2024.109780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 07/04/2024] [Accepted: 07/17/2024] [Indexed: 07/23/2024]
Abstract
The COMMD (Copper Metabolism gene MURR1 Domain) gene family consists of 10 members, which are involved in various biological processes such as copper and sodium transport, NF-κB activity and cell cycle progression. However, the study of COMMD gene family in large yellow croaker (Larimichthys crocea) is largely unknown. In this study, 10 COMMD gene family members (named LcCOMMDs) were successfully identified from large yellow croaker. The results showed that there were differences in the number of LcCOMMDs exons at the level of gene structure, which reflected that they had adjusted and changed accordingly in the process of evolution to adapt to the environment and achieved functional diversification. Through phylogenetic analysis, we found that the LcCOMMDs was highly conserved, indicating their important functions in organisms. It was worth noting that the expression levels of LcCOMMD1, LcCOMMD2, LcCOMMD3, LcCOMMD5 and LcCOMMD10 in the spleen changed significantly after bacterial stress, which suggested that these genes might be involved in the regulation of innate immune response. In addition, the expression levels of LcCOMMD1, LcCOMMD2, LcCOMMD3, LcCOMMD5, LcCOMMD7, LcCOMMD8, LcCOMMD9 and LcCOMMD10 changed significantly after hypoxia exposure, which further proved the role of LcCOMMDs in immune function. In summary, this study not only revealed the important role of COMMD genes in the innate immune response of large yellow croaker, but also provided valuable information for further understanding the regulatory mechanism of COMMD gene family under different conditions.

Comp Biochem Physiol B Biochem Mol Biol 2024; 275:111018. [PMID: 39128537 DOI: 10.1016/j.cbpb.2024.111018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Revised: 08/07/2024] [Accepted: 08/08/2024] [Indexed: 08/13/2024]
Abstract
The mud crab (Scylla paramamosain) is a commercially significant marine decapod crustacean. Due to its obvious sexual dimorphism, the mechanism of sex differentiation and gonadal development has attracted significant research interest. The Dmrt (double-sex and mab-3 related transcription factor) genes are vital in animal gonadal development and sex differentiation. In the present study, miR-34 was predicted to target the 3' end of Dmrt-1, idmrt-2, Dmrt-3, Dsx and Dmrt-like genes by prediction software, and the interactions between miR-34 and these Dmrt genes were validated by in vivo and in vitro experiments. Dual luciferase assay results indicated that miR-34 mimics/inhibitors co-transfected with plasmid vectors with 3' end of Dmrt-1, idmrt-2, Dmrt-3, Dsx and Dmrt-like, respectively, led to a significant decrease/increase of fluorescence activity in HEK293T cells. In vivo experiments showed that injection of agomir-34 significantly inhibited Dmrt-1, idmrt-2, Dsx and Dmrt-like expression, while injection of antagomir-34 caused the opposite result. However, Dmrt-3 expression was not affected by injection of miR-34 reagents. Meanwhile, the expression of spermatogenesis and testicular development-related molecular marker genes (IAG, foxl2 and vasa) in mud crabs was significantly changed after injecting the miR-34 reagent in vivo. Furthermore, the result of immunoblotting proved that the expression level of Dmrt-like protein can be regulated by miR-34. These results imply that miR-34 is indirectly involved in sex differentiation and testicular development of S. paramamosain by regulating Dmrt-1, idmrt-2, Dsx and Dmrt-like genes.

Abstract
In recent years, members of the Dmrt family, TGF-β superfamily and Sox family have been recognized as crucial genes for sex determination/differentiation across diverse animal species. Nevertheless, knowledge regarding the abundance and potential functions of these genes in abalone remains limited. In this study, a total of 5, 10, and 7 members of the Dmrt family, the TGF-β superfamily and the Sox family, respectively, were identified in the Pacific abalone Haliotis discus hannai. Sequence characteristics, phylogenetic relationships and spatiotemporal expression profiles of these genes were investigated. Notably, HdDmrt-04 (Dmrt1/1L-like) emerged as a potential mollusc-specific gene with a preponderance for expression in the testis. Interestingly, none of the TGF-β superfamily members exhibited specific or elevated expression in the gonads, highlighting the need for further investigation into their role in abalone sex differentiation. The Sox proteins in H. discus hannai were categorized into 7 subfamilies: B1, B2, C, D, E, F, and H. Among them, HdSox-07 (SoxH-like) was observed to play a crucial role in testis development, while HdSox-03 (SoxB1-like) and HdSox-04 (SoxC-like) probably cooperate in abalone ovary development. Taken together, the results of the present study suggested that HdDmrt-04 and HdSox-07 can be used as male-specific markers for gonad differentiation in H. discus hannai and imply conservation of their functions across invertebrates and vertebrates. Our findings provide new insights into the evolution and genetic structure of the Dmrt family, the TGF-β superfamily and the Sox family in abalone and pave the way for a deeper understanding of sex differentiation in gastropods.

Abstract
Scavenger receptors (SRs) are pattern recognition receptors involved in the innate immune defense against pathogen infection in fish. However, there has not been much research done on teleosts. In this study, 18 members of the SR gene family were found in large yellow croaker. The identification of the SR gene family showed that the protein length of SR members in large yellow croaker were quite different, and most SR genes were distributed in nuclear and endoplasmic. The evolutionary relationship, exon/intron structure and motif analysis revealed that members of the SR gene family were highly conserved. The results of the expression profiles after Pseudomonas plecoglossicida infection and hypoxia-exposure demonstrated that SR members were involved in inflammatory reactions. Especially, COLEC12 and SCARF1 exhibited substantial changes in response to both P. plecoglossicida and hypoxia stress, indicating their possible immunological functions. The result of this study revealed that SR genes played a vital part in the innate immune response of large yellow croaker, and would give important details for a deeper comprehension of the SR gene family's regulation mechanism under various conditions in large yellow croaker.

Abstract
In recent years, some common themes in the development of sex-specific traits in different animal lineages have started to emerge since the discovery of the Dmrt (doublesex-mab3-related transcription factor gene) genes. Bivalves are characterized by a diversity of sexual systems, including simultaneous hermaphroditism, sequential hermaphroditism, and strict gonochorism. However, to date, no research has focused on the genome-wide characterization and analysis of Dmrt genes in bivalves. In this study, the identification and analysis of Dmrt genes in 15 bivalves were performed using bioinformatics methods. A total of 55 Dmrt genes were retrieved in the studied bivalve genomes. The number of Dmrt genes in different species ranged from 3 to 5. The phylogenetic tree showed that Dmrt genes in bivalves can be subdivided into 5 classes: the Dmrt2-like class, Dmrt3-like class, Dmrt4/5-like class, Dsx-like class, and scallop-specific Dmrt class. The Ka/Ks ratios suggested that all Dmrt classes underwent purifying selection pressure. Furthermore, the spatiotemporal expression of Dmrt genes in four bivalve species suggested that different Dmrt genes may have different functions, and scallop-specific Dmrt genes may play a key role in sex determination/differentiation. In general, this study provides a molecular basis for in-depth examination of the functions of Dmrt genes and phylogenomic analyses in bivalves.

FISH & SHELLFISH IMMUNOLOGY 2023; 138:108818.

Abstract
The signal transducer and activator of transcription (STAT) family members are not only the transcriptional activators, but also play important roles in regulating inflammatory response. Some members have been reported to be involved in innate bacterial and antiviral immunity in aquatic organisms. However, no systematic research on STATs has been found in teleost. In this present study, we characterized six STAT genes in Japanese flounder based on bioinformatics methods, namely PoSTAT1, PoSTAT2, PoSTAT3, PoSTAT4, PoSTAT5 and PoSTAT6. The phylogenetic analysis of STATs in fish indicated that STATs were highly conserved and revealed an absence of STAT5 in a few species. Further analysis of gene structures and motifs showed STAT proteins shared a similar structure and probably had similar functionality in Japanese flounder. The expression profiles of different development stages and tissues demonstrated that PoSTATs exhibited specificity in temporality and spatiality as well as PoSTAT4 was highly expressed in gill. The transcriptome data analysis of E. tarda and temperature stress showed that PoSTAT1 and PoSTAT2 were more respective to these two kinds of stress. In addition, the results also demonstrated that these PoSTATs might regulate immune response in different ways, manifested by up-regulation in E. tarda infection and down-regulation in temperature stress. In a word, this systematic analysis of PoSTATs would provide valuable information about the phylogenetic relationship of STATs in fish species and help understand the role of STAT genes in the immune response of Japanese flounder.

Abstract
The Dmrt (Doublesex-mab3-related transcription factor) gene family is a class of crucial transcription factors characterized by one or several conserved DM (Doublesex/Mab-3) domains. Dmrt family genes can participate in various physiological developmental processes, especially in sex determination/differentiation. Echinoderms are extremely important research objects in various fields, such as sex determination/differentiation and neuroscience. However, to date, the genome-wide characterization and analysis of Dmrt genes in echinoderms have not been investigated. In this study, the identification and analysis of Dmrt genes in 11 representative echinoderms were performed using bioinformatics methods. A total of 43 Dmrt genes have been found in the studied echinoderms, and the number of Dmrt genes in different species ranges from 2 to 5. The phylogenetic tree showed that all Dmrt genes from echinoderms can be subdivided into 5 classes, the Dmrt2-like class, Dmrt3-like class, Dmrt4/5-like class, Dsx-like class, and a novel Dmrt (starfish-specific) class. Furthermore, selective pressure assessment suggested that the Dmrt genes underwent purifying selection pressure. In general, this study provides a molecular basis for echinoderm Dmrt genes and may serve as a reference for in-depth phylogenomics.

Abstract
In brief dmrtb1 performs critical functions in sex determination/differentiation and gonadal development in many organisms, but its role in teleost is rarely studied. Through gene cloning, in situ hybridization, and RNA interference technology, the function of dmrtb1 in testicular development of large yellow croaker (Larimichthys crocea) was studied; our study will be helpful in understanding further the molecular regulation mechanism of Lcdmrtb1/Lcdmrt6 in testicular development in L. crocea, and our results enrich the theory of fish dmrts involved in reproductive regulation and provide a new idea for sex control breeding of L. crocea by manipulating reproductive pathway. Abstract Doublesex- and mab-3-related transcription factor B1 (dmrtb1/dmrt6) belongs to one of the members of DMRT family, which performs critical functions in sex determination and differentiation, gonadal development, and functional maintenance. However, knowledge of its exact mechanism remains unclear in teleost. Very little is known about the role of dmrtb1 in the gonad development of Larimichthys crocea. In this study, a dmrtb1 homolog in L. crocea named as Lcdmrtb1 with the full-length cDNA was isolated and characterized. Except for the conserved DM domain, the other regions had low homology. Of the tissues sampled, Lcdmrtb1 was only found to be highly expressed in the testis. In situ hybridization of testis revealed Lcdmrtb1 in both spermatogonia and spermatocytes. After Lcdmrtb1 interference in the testis cells (LYCT) of L. crocea, the expression levels of Lcdmrtb1 and Lcdmrt1 were significantly decreased; subsequently, testicular cell morphology changed from fibrous to round and their growth rate slowed. Similarly, the expression levels of Lcdmrtb1, Lcdmrt1, sox9a/b, and amh were significantly decreased after RNAi in the testis. Furthermore, it was discovered that the spermatogonia had disappeared, and the Sertoli cells had been reduced. The results of immunohistochemistry showed that the expression of Sox9 protein in the testis was not detected after dmrtb1 was knocked down. These results indicated that the absence of Lcdmrtb1 not only greatly inhibited cell growth and destroyed the morphology of testis cells but also down-regulated Lcdmrt1 expression in the testis. This study will be helpful in understanding further the molecular regulation mechanism of Lcdmrtb1/Lcdmrt6 in testicular development in L. crocea.

Zhong Z, Wang Y, Feng Y, Xu Y, Zhao L, Jiang Y, Zhang Z. The molecular regulation mechanism of dmrt1-based on the establishment of the testis cell line derived from two-spot puffer Takifugu bimaculatus. FISH PHYSIOLOGY AND BIOCHEMISTRY 2022; 48:1475-1494. [PMID: 36445491 DOI: 10.1007/s10695-022-01150-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 11/19/2022] [Indexed: 06/16/2023]
Abstract
The establishment of fish cell lines can provide an important in vitro model for developmental biology, pathology, and genetics and also an effective tool to investigate the interactions and related functions of genes. Two-spot puffer Takifugu bimaculatus is a high economic and nutritional value marine fish in Fujian in recent years. Nevertheless, dmrt1 plays a key role in the male differentiation from invertebrates to vertebrates. To understand the molecular regulatory mechanisms of dmrt1 in T. bimaculatus, a testis cell line called TBTc from a juvenile testis of this organism was established with modified Leibovitz's L-15 medium supplemented with 20% FBS, fish serum, embryo extract, and other growth factors. The TBTc with a stable karyotype can be passaged continuously, which was composed of fibroblast-like cells and expressed the marker genes of male-special cells, dmrt1, and amh, and the absence of vasa expression may rule out the possibility of the presence of germ cells. Therefore, TBTc appeared to consist of the mixture of the Sertoli cell and germ cell of the testis. The dmrt1 was significantly expressed in the testes and slightly expressed in the late embryonic development, illustrating that the dmrt1 may participate in the molecular regulation of gonads development and sex differentiation. With the high transfection efficiency of TBTc by electroporation, the cell lines could be used effectively in the study for the expression of exogenous and endogenous genes. Meanwhile, after the knockdown of dmrt1, the morphological changes and survival rates of cells proved that dmrt1 could affect the growth of testicular cells. Furthermore, with the loss of dmrt1, the expression of male-bias genes amh, sox9, and cyp11a was significantly decreased, and the expression of female-bias genes foxl2, sox3, and cyp19a was increased, which suggested that dmrt1 upregulates amh, sox9, and cyp11a and downregulates foxl2, sox3, and cyp19a to participate in the testis development. As a first fish gonadal cell lines of T. bimaculatus, which can be a more convenient, efficient, and rapid model for the investigation of the expression and function of genes, the results will lay a foundation for the next study of the molecular regulation mechanism in gonadal development and sex determination of fish in the future.

Genome-Wide Identification, Phylogeny, and Expression Profile of the Dmrt (Doublesex and Mab-3 Related Transcription Factor) Gene Family in Channel Catfish ( Ictalurus punctatus). Front Genet 2022; 13:891204. [PMID: 35571040 PMCID: PMC9095985 DOI: 10.3389/fgene.2022.891204] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Accepted: 03/31/2022] [Indexed: 11/13/2022] Open
Abstract
The Dmrt (Doublesex and Mab-3 related transcription factor) gene family is a class of crucial transcription factors characterized by a conserved DM domain related to sex determination and differentiation, which has been systematically described in various teleost fish, but less in channel catfish (Ictalurus punctatus), an important global aquaculture species in the US and China. In this study, seven Dmrt genes from channel catfish genome were identified and analyzed using bioinformatics methods. Seven IpDmrt genes were distributed unevenly across five chromosomes. Synteny analysis revealed that Dmrt1, Dmrt2a, Dmrt2b, Dmrt3, Dmrt4, and Dmrt5 were relatively conserved in teleost fish. Tissue distribution analysis showed that IpDmrt1, IpDmrt2b, IpDmrt5, and IpDmrt6 exhibited sexually dimorphic expression patterns and, among them, IpDmrt1 and IpDmrt6 had high expression levels in the testes, while IpDmrt2b and IpDmrt5 had more significant expression levels in the ovaries than in other tissues. After 17β-estradiol treatment, IpDmrt2b and IpDmrt5 were significantly up regulated, while the expression of IpDmrt1 and IpDmrt6 was significantly repressed in XY channel catfish ovaries compared with XX channel catfish ovaries. The present study provides a comprehensive insight into the Dmrt gene family of channel catfish. The results suggest that IpDmrt1 and IpDmrt6 may play an important role in testis differentiation/development, while IpDmrt2b and IpDmrt5 are critical in ovary development in this species.

Whole-genome resequencing of large yellow croaker (Larimichthys crocea) reveals the population structure and signatures of environmental adaptation. Sci Rep 2021; 11:11235. [PMID: 34045615 PMCID: PMC8159941 DOI: 10.1038/s41598-021-90645-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 05/12/2021] [Indexed: 11/28/2022] Open
Abstract
Large yellow croaker is an economically important fish in China and East Asia. Despite its economic importance, genome-wide adaptions of domesticated large yellow croaker are largely unknown. Here, we performed whole-genome resequencing of 198 individuals of large yellow croaker obtained in the sea or from farmers in Zhoushan or Ningde. Population genomics analyses revealed the genetic population structure of our samples, reflecting the living environment. Each effective population size is estimated to be declining over generations. Moreover, we identified genetically differentiated genomic regions between the sea-captured population in the Zhoushan Sea area and that of the Ningde Sea area or between the sea-captured population and the farmed population in either area. Gene ontology analyses revealed the gene groups under selective sweep for the adaptation to the domesticated environment. All these results suggest that individuals of the large yellow croaker populations show genomic signatures of adaptation to different living environments.

Abstract
Doublesex and mab-3 related transcription factors (Dmrts) play crucial roles in sex determination/differentiation and gonad development. The information on Dmrts and their functions are still scarce in mud crab Scylla paramamosain. In this study, 12 published transcriptome data of S. paramamosain were retrieved, pooled, and assembled. From the assembly, 7 Dmrt gene family members were identified and consisted of Spdmrt-like, Spdmrt-1a, Spdmrt-3, Spdmrt-11E, Spidmrt-1, Spdoublesex (Spdsx), and Spidmrt-2. These dmrt genes were predicted to encode 224 aa, 465 aa, 435 aa, 276 aa, 520 aa, 552 aa, and 266 aa protein precursors, respectively. The expression patterns of the dmrt genes were characterized by semi-quantitative PCR. The Spdmrt-like and Spdmrt-1a were exclusively detected in gonads, of which both expression levels in the testis were higher than that in the ovary. The Spdmrt-3, Spdmrt-11E, Spidmrt-1, Spdsx, and Spidmrt-2 were observed in various tissues; all these genes were sexually dimorphic except for dmrt-11E. Specifically, the expression level of Spdmrt-3 and Spidmrt-2 were higher in the testis than that in the ovary. On the contrary, the Spdsx and Spidmrt-1 expression level were higher in ovary than that in testis. The present study's findings provided a fundamental understanding of Dmrt gene family members involving sex determination/differentiation and gonad development in the S. paramamosain.
