Abstract
Chinese sturgeon Dmrt gene family was identified and characterized for the first time. A total of 5 putative Dmrt genes were identified. The gene structure, conserved protein domain and the phylogenetic relationship of Dmrt gene family were systematically analyzed. The expressed profile of Chinese sturgeon Dmrt genes in gonad, pituitary and hypothalamus in the male and female were investigated. The results indicated that the accumulation of Dmrt genes was involved in different tissues, and the expression profile also differed among each Dmrt genes. ASDmrt1A, ASDmrt2, ASDmrt3, and ASDmrtA1 were highly expressed in the testis in comparison with other tissue. This result showed that ASDmrt1A, ASDmrt2, ASDmrt3, and ASDmrtA1 played an important role in the development of testicle, and may be useful tool in distinguishing between male and female of Chinese sturgeon. Our study will provide a basis for additional analyses of Chinese sturgeon Dmrt genes. This systematic analysis provided a foundation for further functional characterization of Dmrt genes with an aim of study of Chinese sturgeon Dmrt gene family.

Abstract
This research identified 169 known microRNAs (miRNAs), 380 novel miRNAs, and 30,538 targets in 11 tissues (blood, brain, derma, gill, heart, intestine, kidney, liver, muscle, pronephros, and spleen) from grass carp Ctenopharyngodon idella with high-throughput sequencing (HTS). Transcripts per million (TPM) expression analysis detected 41 brain-enriched miRNAs (accounting for 61.19% of all tissue-enriched miRNAs). Real-time quantitative PCR (RT-qPCR) confirmed that 21 of 24 randomly selected tissue-enriched miRNAs from the TPM analysis were indeed tissue-enriched (P < 0.05), suggesting the HTS and TPM analyses were reliable. Nine of the 41 brain-enriched miRNAs are complementary to members of the double-sex and mab-3 related transcription factor family (dmrt) involved in sex differentiation. RT-qPCR revealed that cid-miR-138 was more highly expressed in testis than in ovary (P < 0.01), while the reverse was true for target gene dmrt4a (P < 0.01). This opposite expression pattern suggested the direct participation of cid-miR-138-dmrt4a in neuroendocrine mechanisms related to brain-pituitary networks during sex development. The discovery of miRNAs from 11 C. idella tissues expands the available fish miRNA database, and enhances our understanding of the role of sex-related miRNAs in tissue differentiation and maintenance of specific tissue functions in fishes.

Abstract
Transcription factors encoded by the Dmrt gene family regulate multiple aspects of animal reproduction. Most studies investigating the Dmrt gene family were conducted in model organisms from bilateral species, with a particular emphasis on gene function in male sex determination. It is still unclear whether the E. ancora Dmrt (EaDmrt) genes found in basal metazoans such as cnidarians share similar characteristics with orthologs in other metazoans. In this study, seven full Dmrt gene transcript sequences for a gonochoric coral, Euphyllia ancora (phylum: Cnidaria; class: Anthozoa), were obtained through transcriptome data mining, RT-PCR analysis, rapid amplification of cDNA ends, and sequencing. These EaDmrts were subjected to quantitative assays measuring temporal and tissue-specific expression. Results demonstrated a unique gene expression pattern for EaDmrtE, which is enriched in female germ cells during the spawning season. Based on the phylogenetic analyses performed across the homologous Dmrt genes in metazoans, we found that the female-specific EaDmrtE gene is not related to the DM1 gene of Acropora spp. coral nor to Dmrt1 of vertebrates, which are involved in sexual reproduction, especially in sex determination (vertebrate Dmrt1). Additionally, high levels of EaDmrtE transcripts detected in unfertilized mature eggs are retained in newly formed zygotes but decrease during embryonic development. We suggest that the newly discovered gene may play a role in oogenesis and early embryogenesis as a maternal factor in corals. Therefore, the sexual reproduction-associated Dmrt gene(s) should have arisen in cnidarians and might have evolved multiple times in metazoans.

Abstract
The Dmrt genes encode a large family of transcription factors with a conserved zinc finger-like DNA-binding DM domain. The function of Dmrt1, one of the family members, in sexual development has been well studied in invertebrates and vertebrates. In the present study, the full-length cDNA of Dmrt1 was isolated from the testis of Sebastes schlegeli. The full-length cDNA of S. schlegeli Dmrt1 (SsDmrt1) was 1,587 bp and contained a 189-bp 5' UTR, a 489-bp 3' UTR and a 909-bp open reading frame, which encoded 302 amino acids with a conserved DM domain and an male-specific motif domain. Phylogenetic analysis showed the evolutionary relationships of SsDmrt1 with other known Dmrt genes in fish and tetrapods. Several transcriptional factor-binding sites in the 5' promoter were identified that might regulate SsDmrt1 expression. Quantitative real-time PCR analysis indicated that SsDmrt1 was expressed in all of the inspected larval developmental stages from 1 to 35 days after birth and that the level of expression gradually decreased. The expression of SsDmrt1 in adult gonads was sexually dimorphic with extremely high expression in the testis, but very low expression in the ovary. No expression was detected in other tissues. Using in situ hybridization, we demonstrated that SsDmrt1 was specifically expressed in the germ cells of both the testis and the ovary. Thus, our results suggest that SsDmrt1 may have an important role in the differentiation of both the testis and the ovary of S. schlegeli.

Abstract
The full length of vasa cDNA in blue tilapia Oreochromis aureus was cloned and sequenced using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE). Nucleotide sequence analysis revealed that the cDNA contained 2,143 bp and was consisted of a 48-bp 5' untranslated terminal region (5'-UTR), a 157-bp 3' untranslated terminal region (3'-UTR) and a 1,938-bp open reading frame (ORF) which encoded 645 amino acids. Homological protein analysis showed that vasa in O. aureus was highly conserved with Nile tilapia Oreochromis niloticus. Tissue distribution expression analysis indicated that vasa was specifically expressed in the gonads. Using in situ hybridization, we found that vasa was expressed in spermatogonia and spermatocytes rather than spermatids and sperm. In order to examine the influence of luteinizing hormone releasing hormone analog (LHRH-A) on vasa, the in vivo injections were performed different concentrations of LHRH-A. Our results showed that LHRH-A induced meiosis and down-regulated vasa mRNA expression. In summary, our results showed that vasa was specifically expressed in gonads and LHRH-A inhibited vasa expression in the testis. Our results also suggested that LHRH-A could regulate vasa gene expression in O. aureus testis.

Abstract
A plethora of corroborative genetic studies led to the view that, across the animal kingdom, the gene-regulatory cascades triggering sexual development bear little resemblance to each other. As a result, the common emerging picture is that the genes at the top of the cascade are not conserved, whereas the downstream genes have homologues in a much broader spectrum of species. Among these downstream effectors, a gene family involved in sex differentiation in organisms as phylogenetically divergent as corals, Caenorhabditis elegans, Drosophila, frogs, fish, birds and mammals is the dmrt gene family. Despite the attention that Dmrt1 factors have received, to date it has not been elucidated how Dmrt1s mediate their activities and putative downstream targets have yet to be characterized. However, a remarkable amount of descriptive expression data has been gathered in a large variety of fish, particularly with respect to early gonadal differentiation and sex change. This minireview aims at distilling the current knowledge of fish dmrt1s, in terms of expression and regulation. It is shown how gonadal identities correlate with dimorphic dmrt1 expression in gonochoristic and hermaphroditic fish species. It is also described how sex steroid hormones affect gonadal identity and dmrt1 expression. Emphasis is also given to recent findings dealing with transcriptional, post-transcriptional, post-translational and functional regulations of the dmrt1a/dmrt1bY gene pair in medaka.

Abstract
Ikaros, an important transcription factor plays a role in the development of hemato-lymphoid system, yet its functional importance in fish macrophages remains unknown. In this study, an Ikaros cDNA was cloned from the half-smooth tongue sole Cynoglossus semilaevis. The cDNA contained an open reading frame of 1,290 nucleotides that encoded a 430 amino acid protein. The deduced protein is structurally similar to dul from other species, for example human, axolotl, and possesses 3-zinc finger and 2-zinc finger domains at its N- and C-termini, respectively. Phylogenetic analysis revealed C. semilaevis Ikaros to be grouped with all the fish Ikaros, but branching from other Ikaros family members. Both semi-quantitative PCR and quantitative real-time PCR indicated Ikaros to be predominantly expressed in the immune-relevant tissues such as kidney, thymus, spleen and liver. In the macrophages cultured from C. semilaevis head kidney and challenged with lipopolysaccharide and lipoteichoic acid not only induced expression of the proinflammatory cytokines tumor necrosis factor-alpha and interleukin 1-beta but also caused up-regulation of Ikaros in a dose- and time-dependent fashions. All these data suggest that Ikaros might be a useful marker for inflammatory responses in C. semilaevis.

Abstract
R-spondin1 (RSPO1) is a potential female-determining gene in human (Homo sapiens) and mouse (Mus musculus). Its differential expression in these mammals is correlated with signaling for sex determination. As a way of studying sex determination in fish we cloned and analyzed a RSPO1 gene in zebrafish (Danio rerio). Using real-time PCR, we observed that RSPO1 is expressed more strongly in ovaries than in testes, suggesting that RSPO1 may have a role in gonad differentiation. High RSPO1 expression was detected in some non-gonadal organs like muscle and kidneys. In situ hybridization results demonstrate that RSPO1 is expressed in premature germ cells, in oogonia and primary oocytes in ovaries and in spermatogonia and spermatocytes in testes. It is also expressed in gonad somatic cells during gonadal development: in granulosa cells and theca cells of early and late cortical-alveolar stage follicles in ovaries, and in Leydig cells in testes. This differential expression may indicate that RSPO1 has a role(s) in zebrafish gonad development and differentiation. By fusing zebrafish RSPO1 with a green fluorescent protein gene, we found that RSPO1 is located in the cytosol and Golgi apparatus but not the nucleus of fish epithelioma papulosum cyprinid (EPC) cells. These preliminary findings suggest some aspects of RSPO1 like differential expression linked to sex determination may be conserved in fish while other aspects like subcellular localization differ from the mammalian RSPO1.
