Skin multi-omics-based interactome analysis: Integrating the tissue and mucus exuded layer for a comprehensive understanding of the teleost mucosa functionality as model of study
Ontology highlight
ABSTRACT: In this study, we analyzed both together the epithelial tissue and the secreted mucus response using a holistic interactome-based multi-omics approach. The effect of the gilthead sea bream (Sparus aurata) skin mucosa to a dietary inclusion of spray-dried porcine plasma (SDPP) was evaluated.
Project description:A gilthead sea bream (Sparus aurata) microarray platform was developed to identify brain gene expression profiles in response to environmental concentrations of human pharmaceuticals.
Project description:A gilthead sea bream (Sparus aurata) microarray platform was developed to identify brain gene expression profiles in response to environmental concentrations of human pharmaceuticals. Comparative analysis of gene expression profiles was conducted among brain of gilthead seabream exposed to Acetaminophen (APAP; analgesic), Carbamazepine (CBZ; anti-epileptic) and Atenolol (AT; β-blocker). All groups of samples were also compared with brain of control individuals.
Project description:Sparicotylosis is an endemic parasitic disease across the Mediterranean Sea caused by the polyopisthocotylean monogenean Sparycotyle chrysophrii, which affects the gills of gilthead sea bream (Sparus aurata). Current disease-management, mitigation and treatment strategies are scarce against sparicotylosis. In order to successfully develop more efficient therapeutic strategies against this disease, understanding which molecular mechanisms and metabolic pathways are altered in the host is critical. This study aims to elucidate how S. chrysophrii infection modulates giltheadd seea bream physiological status and to identify the main altered biological processes through plasma proteomics of the host.
Project description:This study aimed to unveil the biological mechanisms modulated in response to the dietary administration of SDPP in the gilthead sea bream gut.

Project description:Deciphering the dietary immunomodulatory effects of a medicinal plant leaf extract (MPLE) obateined from sage (Salvia officinalis, Lamiaceae) and lemon verbena (Lippia citriodora, Verbenaceae) upon the gut-associated lymphoid tissue (GALT) of gilthead seabream (Sparus aurata).
Project description:Analysis of the gene expression profiles of Sparus aurata head kidney after infection with Photobaterium damselae piscicida. The expression levels of 21,497 sea bream transcripts, on both directions, 24 and 48 hours post-infection, were compared with the levels detected in uninfected individuals.
Project description:The transcriptome of haploid germ cells and ejaculated spermatozoa from wild-type seabream (Sparus aurata) was compared by RNAseq. The data establish the molecular signature during spermatozoa differentiation and reveal the involvement of novel endocrine mechanisms during sperm maturation in the efferent duct.
Project description:Transcriptional profiling of adipose tissue comparing three diets with different levels of replacement of fish oil for vegetable oils. Juvenile gilthead sea bream (Sparus aurata L.) of 16 g initial mean body weight were distributed into 9 fibreglass tanks (500 l) in groups of 60 fish at the research experimental facilities of IATS. Each group received (from May 23rd to September 19th) one of the three experimental diets nominally CTRL, 66VO and VO. All diets were based on plant proteins and dietary oil was either Scandinavian FO (CTRL diet) or a blend of vegetable oils, replacing the 66% (66VO diet) and 100% (VO diet) of FO. Four samples, using a control diet (CTRL) as reference and double color hybridization and dye swap with the other two (66VO, VO)
Project description:We report the proteomic characterization of livers from Sparus aurata exposed to cold temperatures. In this study, mimicking the winter challenge conditions, a 8 week feeding trial was carried out on gilthead sea bream juveniles reared in RAS systems at a temperature ramp made of two phases of four weeks each: a cooling phase from 18°C 8 (t0) to 11°C (t1) and a cold maintenance phase at 11°C (t2). Sparus aurata livers, after exposure to the three temperature phases (t0, t1 and t2), were collected and analyzed using a shotgun proteomics approach based on filter-aided sample preparation followed by tandem mass spectrometry, peptide identification carried out using Sequest-HT as search engine within the Proteome Discoverer informatic platform, and label-free differential analysis. Along the whole trial, sea breams underwent several changes occurring upon thermal stress in liver protein abundance. These occurred mostly during the cooling phase, when catabolic processes were mainly observed. These included protein and lipid degradation and a decrease in protein synthesis and amino acid metabolism. A decrease in protein mediators of oxidative stress protection was also seen. Liver protein profiles showed less marked changes during cold maintenance, although pathways such as the methionine cycle and sugar metabolism were significantly affected. This study provided useful hints on the dynamics and extent of the metabolic shift occurring in sea bream liver with decreasing water temperature, helping the development of feeds aimed at compensating the thermal stress encountered by fish in offshore farming conditions.
