Modulation of the Liver Protein Carbonylome by the Combined Effect of Marine Omega-3 PUFAs and Grape Polyphenols Supplementation in Rats Fed an Obesogenic High Fat and High Sucrose Diet.

ABSTRACT: Diet-induced obesity has been linked to metabolic disorders such as cardiovascular diseases andtype 2 diabetes. A factor linking diet to metabolic disorders is oxidative stress, which can damagebiomolecules, especially proteins. The present study was designed to investigate the effect of marineomega-3 polyunsaturated fatty acids (PUFAs) (eicosapentaenoic acid (EPA) and docosahexaenoic acid(DHA)) and their combination with grape seed polyphenols (GSE) on carbonyl-modified proteins fromplasma and liver in Wistar Kyoto rats fed an obesogenic diet, namely high-fat and high-sucrose (HFHS)diet. A proteomics approach consisting of fluorescein 5-thiosemicarbazide (FTSC) labelling of proteincarbonyls, visualization of FTSC-labelled protein on 1-DE or 2-DE gels, and protein identification byMS/MS wa
