Project description:The Senegalese sole (Solea senegalensis) is a marine flatfish of high economic value and a target species for aquaculture. Here, we used a transcriptomic approach to investigate changes in genes expressed in the Senegalese sole testis throughout spermatogenesis in wild-caught fish adapted to captivity. We identified approximately 400 genes that are differentially expressed during the progression of spermatogenesis and that participate in processes such as activation of the ubiquitin-proteasome system, sperm maturation and motility, cell adhesion or cytoskeletal remodeling. The results from this study contribute to our understanding of the molecular changes ocurring during spermatogenesis in the Senegalese sole.

Project description:Betanodaviruses (VNNV) are the causative agents of the viral nervous necrosis, a disease that affects cultured Senegalese sole (Solea senegalensis). VNNV reassortant strains, combining genomic segments from the RGNNV and SJNNV genotypes, have previously been isolated from wild and farmed several fish species. The wild reassortant wSs160.03 isolated from sole has been proved to be more virulent for sole than the parental genotypes (RGNNV and SJNNV), causing 100% mortality. Mutations of wSs160.03 strain performed by reverse genetic, have allow to obtain a mutant reassortant strain (rSs160.03247+270) with mutations at amino acids 247 (serine to alanine) and 270 (serine to asparagine), which provoke a 40% decreased mortality. In the current study, the RNA-Seq technology has been used to compare the Senegalese sole transcriptomes in two organs (head-kidney and eye/brain) after infection with the wild reassortant strain and the mutant reassortant strain. A total of 633 genes were differentially expressed (DEGs) in animals infected with the wSs160.03 strain, whereas only 393 genes were differentially expressed in animals infected with the rSs160.03247+270 strain, indicating a 37.9% decrease in the number of DEGs after infection with the mutated reassortant strain. An inversion in the proportion of genes up/down-regulated in nervous tissue of these animals was also obtained for both reassortants. To understand the biological functions of identified DEGs involved in VNNV infection, a gene ontology (GO) enrichment analysis was performed with fold change > 1.5 (up- or down-regulated) and p-value < 0.05. Different profiles of GO were obtained in the subclasses biological process, cellular component, and molecular function for each reassortant strains. Regarding the immune response, genes coding for proteins acting as mediators of IFN type I expression (DHX58, IRF3, IRF7) and IFN-stimulated genes (ISG15, Mx, PKR, Gig1, ISG12, IFI44, IFIT-1, to name a few) were up-regulated in animals infected with the wild type reassortant, whereas no-differential expression of these genes was observed in animals infected with the mutant reassortant. The different transcriptomic profiles obtained could help to better understand VNNV pathogenesis in Senegalese sole, setting up the importance as virulence determinants of amino acids at positions 247 and 270 within the RNA2 segment.

The results from this study contribute to our understanding of the molecular changes ocurring during spermatogenesis in the Senegalese sole. This study represents spermatogenesis in Solea senegalensis: mid versus late spermatogenesis. Total RNA from testes at different stages in spermatogenesis (early, mid, late and functional maturation) from F0 wild Senegalese sole (3-4 animals at each stage) was extracted using the RNeasy extraction kit (Qiagen) and treated with DNAse following the manufacturer’s instructions. Quantitative and qualitative analysis of total RNA was performed using the Agilent 2100 bioanalyzer. RNA samples from each stage were pooled and amplified, labelled and hybridized to a custom-made oligonucleotide microarray containing 5,087 Senegalese sole Unigene sequences. In brief, pooled testicular RNAs from each stage were amplified and the resulting cRNAs labelled with Cy3 and Cy5, respectively, mixed in equal amounts and hybridized to the microarray for 17 h at 60 ºC.

Project description:In male teleosts, testicular steroids are essential hormones for the regulation of spermatogenesis and their production is regulated by pituitary gonadotropins. In the Senegalese sole (Solea senegalensis), an economically important flatfish with semi-cystic and asynchronous spermatogenesis, the endocrine mechanisms involved in the regulation of spermatogenesis, particularly regarding the production and regulation of testicular steroids, are not well understood.This study aimed at describing the transcriptomic changes taking place in the Senegalese sole testis in response to hCG stimulation in vivo. Gene expression analysis by microarray identified 90 differentially expressed genes in the testis in response to hCG administration, including genes potentially involved in steroidogenesis, progression of spermatogenesis and germ cell maturation and cytoskeletal organization. Our results provide evidence for the first time that key genes involved in the regulation of steroid production and spermatogenesis in the Senegalese sole testis are under gonadotropic control.
