Project description:The goal of this study was to gain a better understanding of the genetic background of gonadal maturation of the European eel and to use gene expression profiles to identify predictive markers for broodstock selection that can be measured in blood samples. To find leads for maturation markers we performed a pilot deep-sequencing transcriptome analysis of ovarian tissue derived from a yellow eel, a prepubertal silver eel and a post-spawning matured eel. Among the best leads were two key players in steroidogenesis, namely pP450c17 and liver receptor homolog-1.

Project description:The swamp eel or rice field eel (Monopterus albus) taxonomically belongs to the family Synbranchidae of the order Synbranchiformes (Neoteleostei, Teleostei, Vertebrata). It is not only an economically important freshwater fish in aquacultural production, but also an increasingly known model species for biological studies. Understanding molecular mechanisms underlying sex change is a major area of interest. The swamp eel thus offers a powerful system for studying sexual development and adaptive evolution in vertebrates.The whole genome sequencing provides valuable resources for sex control in fish production, species protection through manipulating sex reversal genes, and potentially enabling effective population control and promoting reproduction health in human.

Project description:Background: The Japanese eel (Anguilla japonica) holds significant economic value in East Asia, but limitations in understanding its reproductive biology have hindered advancements in artificial breeding techniques. Previous research has primarily focused on conserved sex differentiation genes, offering limited insights into the broader molecular mechanisms driving gonadal development and sexual dimorphism. To address these limitations, this study aims to investigate key genes and pathways involved in gonadal development through a comprehensive transcriptomic analysis of male and female eel gonads. Results: PacBio Iso-Seq and Illumina RNA-Seq technologies were combined to conduct a full-length transcriptome analysis of male and female Japanese eel gonads at a post-differentiation, pre-maturation stage. A total of 24661 unigenes were identified in ovaries and 15023 in testes, along with genomic regulatory elements such as transcription factors, simple sequence repeats, and long non-coding RNAs. Additionally, 1,210 differentially expressed genes were detected. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses revealed significant pathways involved in cell cycle regulation, metabolic processes, apoptosis, and hormone activity. Notably, several reproductive-related genes, including bambi, ccnb1, cdc20, gdf9, prlh, ccdc39, chrebp, tspo, syce3, and ngb, demonstrated significant dimorphic expression in eel gonads. Conclusions: This study provides valuable insights into the molecular mechanisms of gonadal differentiation and sexual dimorphism in Japanese eels. The findings expand the genetic resources available for the eel breeding industry and could facilitate the development of improved artificial breeding techniques focused on reproductive development.

Project description:Vibriosis caused by Vibrio vulnificus on eels represents an important threat for this specie under culture conditions. Development of new transcriptomic tools is essential to increase the knowledge of eel biology, that nowadays is scarcer. Therefore, using previous results obtained by 454 sequencing of the eel immune-enriched transcriptome, an eel-specific custom microarray have been designed. Gills transcriptomic pattern were analyzed as a principal portal of entry for pathogens in fish after 1h of bath infection with Vibrio vulnificus to describe gill immune response. Moreover, two different strains were used, vibro vulnificus wild type (R99) and rtx double mutant (CT285), to asses the virulence of these pathogen caused by MARTX.

Project description:The French ICGC project on liver tumors is coordinated by Pr Jessica Zucman-Rossi and funded by Inca (French Institute for Cancer). The aim of the present project is to identify the catalog of somatic and germline mutations in liver tumors using whole genome (WGS) and whole exome sequencing (WGS), integrated with DNA methylation and RNA sequencing (RNA-seq) data. The present series corresponds to 161 RNA-seq samples from tumors with matched WES or WGS. Hepatocellular carcinoma (HCC) accounts for more than 90% of liver cancers, and is a major health problem. It is the 3rd cause of cancer-related mortality. Advances in genomic analyses have formed a comprehensive understanding of different underlying pathobiological layers resulting in hepatocarcinogenesis. Thus, the development of next-generation sequencing technologies has made it possible to generate more comprehensive catalogues of somatic alteration events (single nucleotide substitutions, structural variations, and epigenetic changes) in liver cancer genome than ever before.

Project description:Japanese eel (Anguilla japonica) is a migratory fish with high economic value. The gonads of eels cultured in captivity do not mature naturally, and under artificial ripening, their hypothalamic-pituitary-gonadal axis is activated and the maturation coefficient of the gonads is significantly increased. Previous studies on eel breeding have focused on reproductive physiological processes, with limited insight into the molecular mechanisms in the pituitary gland that influence ovarian development. To address these limitations, we used pituitary tissues of female Japanese eels as samples for Pacbio Iso-Seq and RNA-Seq combining analyses, selecting pre-matured (PP) and after-matured (AP) samples to investigate DEGs and signal pathways regulating gonadal development in the pituitary gland, respectively.
