Atherosclerosis development and progression have been linked to vascular reactive oxygen species (ROS). Plaque formation and especially instability, frequently resulting in acute coronary syndromes, have been linked to cell apoptosis and senescence, but also mainly to increased cellular oxidative stress. ROS are characterized by their high chemical reactivity and a resulting short half-life. This high reactivity usually involves reversible and/or irreversible protein modifications and specifically the covalent oxidative modification of cysteine residues. The latter can be used for the identification of protein-chemical footprints, leading to indirect monitoring of ROS. Proteomics and especially liquid chromatography tandem mass spectrometry (LC-MS/MS) approaches have emerged as a powerful tool to identify such protein modifications in biological samples (e.g., body fluids, tissues, cells). Application of a well-established quantitative thiol trapping technique termed OxICAT enables the detection and quantification of oxidative thiol modifications of thousands of proteins in a single experiment. In this chapter, a step-by-step guide for the redox proteomics analysis of atherosclerotic aortas, by utilizing the OxICAT method, as optimized by our group is provided.
