Alcohol-induced alterations in maternal uterine endothelial proteome: a quantitative iTRAQ mass spectrometric approach.
Ontology highlight
ABSTRACT: Objective
To quantitate alcohol-induced alterations in the maternal uterine endothelial proteome utilizing iTRAQ-based mass spectrometry.Study design
Uterine artery endothelial cells from third trimester pregnant ewes were FAC sorted, validated and treated without or with binge-like alcohol. Lysates were trypsin digested, iTRAQ-labeled, and analyzed using nano LC MS/MS.Results
Alcohol significantly upregulated 14 and downregulated 17 proteins (P<0.05) including those related to cell structure, transcription/translation regulation, histones, Ca(2+)/NO, and redox balance. Gene Ontology and ArrayTrack analyses revealed alterations to protein processing, binding, and nutrient metabolism pathways. Further, alcohol altered proteins previously correlated with fetal alcohol spectrum disorders (FASD) and those that regulate epigenetic, transcriptional, and translational processes.Conclusions
Alcohol differentially alters the proteome in the maternal uterine compartment at the level of the endothelium. iTRAQ mass spectrometry provides a robust high throughput platform to comprehend the multi-mechanistic actions of alcohol and develop appropriate biomarkers and ameliorative measures for FASD.
