Dataset of the proteome profiles of sea bass (Dicentrarchus labrax) skin-scale exposed to estradiol and fluoxetine

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.
