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:Contamination of aquatic ecosystems with anthropogenic pollutants, including pharmaceutical drugs, is a major concern worldwide. Fish are particularly at risk of exposure to pollutants but their impacts on mineralized fish tissues, particularly the scales that form a barrier between the fish and the environment, are poorly understood. The proteome data here presented support the findings reported in the associated research article “Disruption of the sea bass (Dicentrarchus labrax) skin-scale by estradiol and fluoxetine, an emerging pollutant”. Juvenile sea basses were exposed by intraperitoneal injections to: a) the antidepressant fluoxetine (FLX), a widely prescribed psychotropic drug and an emerging pollutant; b) the natural estrogen 17β-estradiol (E2) and c) coconut oil alone (control). The scale proteome profiles of fish exposed to these compounds for 5 days were analysed by the quantitative label-free proteomics technology SWATH-MS (Sequential Windowed data-independent Acquisition of the Total High-resolution-Mass Spectra). LC-MS data from pooled protein extracts from the scales of all experimental groups were acquired using information-dependent acquisition (IDA), which allowed the identification of 1,254 proteins through searches against the sea bass genome database. 715 proteins were confidently quantified by SWATH acquisition, from which 213 proteins had modified levels (p<0.05) between E2- or FLX-exposed fish and control. The main biological processes and KEGG pathways affected by E2 or FLX treatments were identified using Cytoscape/ClueGO enrichment analyses.
