Project description:Pubertal development in males starts with the onset of spermatogenesis that implies the division of primary spermatogonia and their subsequent entry into meiosis. Whole genome microarray expression profile was used as a means to explore the molecular basis underlying the onset of pubertal development in sea bass. The present study is aimed at the characterization of the expression of genes involved in the onset of spermatogenesis in the European sea bass. The study is focused on the first stages of the process including the appearance of spermatocytes and thus the first meiotic divisions. The transcriptomic study using a sea bass-specific microarray resulted in a number of genes differentially expressed during the onset of spermatogenesis. Among those, genes involved in cell-cycle progression, microtubule assembly during meiosis or retinoic acid signaling pathway indicating that they can be used as potential molecular markers for the onset of spermatogenesis in sea bass.

Project description:We have further tested and validated a reproduction-enriched microarray designed specifically for European sea bass providing a reliable tool to study gene expression patterns in this fish species. Results obtained by using this platform helped to increase our knowledge in the gene cascade of sex differentiation and give evidence of the complexity of the molecular processes. We described the gene expression profile of genes and pathways required to differentiate bipotential tissue to either an ovary or testis providing a deep transcriptomic analysis in the developing gonads. Resulting data may help to improve sex control in fish culture particularly in the European sea bass

Project description:Understanding the molecular basis of stress is crucial in biology and of long standing interest in fish science. We tackled this question by modifying the epiGBS (epiGenotyping By sequencing) technique to screen for cytosine methylation and explore the genome-wide epigenomic response to a three months repeated acute stress challenge in the European sea bass (Dicentrarchus labrax). Following a minimally invasive sampling using nucleated red blood cells (RBCs), our modified epiGBS protocol retrieved 501,108,033 sequencing reads after trimming, with a mean mapping efficiency of 73.0% for unique best hits. Sequencing reads were shown to map across all linkage groups (LGs) of sea bass. A total of 47,983 CpG coordinates with a minimum 30X read depth was retained for differential methylation analysis between pre- and post-stress fish. A strong family effect was demonstrated, and fifty-seven distinct differentially methylated cytosines (DMCs) distributed on 17 of 24 LGs were found between RBCs of pre- and post-stress individuals. Twelve of them were located in intergenic regions, one in a repeated element; and forty four in gene bodies. Overall, DMCs were found inside or in the vicinity of 51 distinct genes shown previously to be related to stress. Thirty-eight of these genes were previously reported as differentially expressed in the brain of zebrafish, most of them involved in stress coping differences.

Project description:A custom high density oligo-microarray (8 x 15K) was designed and printed by means of the eArray web tool (Agilent) to analyze the transcriptome of the three intestinal sections of Euroipan sea bass (Dicentrarchus labrax). Naïve stock juveniles sea bass, maintained under intensive rearing conditions in the indoor experimental facilities of IATS, were sampled after overnight fasting for anterior, middle and posterior sections of intestine. The array comprised 60-oligomer sequences for 14,147 different sea bass annotated sequences. Total RNA (150ng) from individual fish were labelled with cyanine 3-CTP and 1,000ng of each labelled cRNA were hybridized to microarray slides. Analysis of the scanned data, including principal component analysis and unpaired t-test with Benjamini-Hochberg multiple testing correction, was carried out with GeneSpring GX software (Agilent). Pathway analysis of differentially expressed sequences was performed using the Ingenuity Pathway Analysis (IPA) software.

Project description:Fresh fish are highly perishable food products and their short shelf-life limits their commercial exploitation, leads to waste and has a negative impact on aquaculture sustainability. New non-thermal food processing methods, such as High pressure (HP), are being investigated to prolong shelf-life while assuring high food quality. We applied several tools to evaluate the impacts of HP processing on European sea bass (Dicentrarchus labrax) fillets quality and shelf life. The data here presented includes visual and physical measurements of flesh quality and the microbiome and proteome profiles of control and HP-processed sea bass fillets (600MPa, 25ºC, 5min), after isothermal storage (2°C) for different periods ranging from 1 to 67 days. Color (L-, a- and b- values) change and texture (hardness, cohesiveness and adhesiveness) parameters were obtained by using appropriate colorimeter and texture analyser, respectively, during refrigerated storage. Bacterial diversity was analysed by Illumina high-throughput sequencing of the 16S rRNA gene in five pooled DNAs from control or HP-processed fillets after 1, 11 or 67 days and the raw reads were deposited in the NCBI-SRA database with accession number PRJNA517618. In addition, high-throughput sequencing of the internal transcribed spacer (ITS) region targeting yeast and moulds was run for control or HP-processed fillets at the end of storage (11 or 67 days, respectively), being deposited under SRA accession PRJNA517779. Quantitative label-free proteomics profiles were analysed by SWATH-MS (Sequential Windowed data independent Acquisition of the Total High-resolution-Mass Spectra) in myofibrillar or sarcoplasmic enriched protein extracts pooled for control or HP-processed filets after short (1d) or long-term (11-67 days) storage. These data support the findings reported in “High pressure processing of European sea bass (Dicentrarchus labrax) fillets and tools for flesh quality and shelf life monitoring” (Tsironi et al. 2019).

Project description:Comparison of the hepatic transcriptomes for two half-sib-families of European sea bass fed on vegetable and fish diet. These two half-sib-families exhibit similar growth on fish diet while significantly different on vegetable diet. The aim of the study is to point out the large panel of metabolic and physiological effects induced by total substitution of both fish meal and fish oil in the diets of European sea bass and to reveal physiological characteristics associated to the two half-sib-families.

The aim of the study is to point out the large panel of metabolic and physiological effects induced by total substitution of both fish meal and fish oil in the diets of European sea bass and to reveal physiological characteristics associated to the two half-sib-families. Fish from both two half-sib-families (G and g) were fed a a fish diet (FD) or a vegetable diet (VD) diet for 9 months. Five to eight independent experiments were performed for each experimental groups (G-FD; G-VD; g-FD; g-VD) using different fishes for each experiment.
