[Dataset] Assessment of endocrine disruptors effects on zebrafish (Danio rerio) embryos by untargeted LC-HRMS metabolomic analysis
The exposure protocol involved zebrafish embryos exposed in groups of 20 to various concentrations of chemical compounds, with five replicates per treatment. The concentrations ranged from the lowest observed effect concentrations (LOECs) to control levels. After exposure, embryos were collected, wa...

| Sumario: | The exposure protocol involved zebrafish embryos exposed in groups of 20 to various concentrations of chemical compounds, with five replicates per treatment. The concentrations ranged from the lowest observed effect concentrations (LOECs) to control levels. After exposure, embryos were collected, washed, frozen, and stored. Metabolites were extracted from individual embryo pools using methanol and methionine sulfone. The extraction process included vortexing, sonication, and centrifugation, followed by addition of water and chloroform. The aqueous fraction was dried and reconstituted using acetonitrile-water solution. Liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) was used for analysis. Chromatographic separations were carried out on a hydrophilic interaction liquid chromatography (HILIC) column. Mass spectrometry was performed using an Orbitrap mass spectrometer with electrospray ionization in positive and negative modes. The mass spectra were acquired at high resolution, and fragmentation scans were used for metabolite identification. The overall process aimed to analyze the metabolomic profile of zebrafish embryos exposed to different chemical concentrations. |
