Effect of FOM, GSE, and FOM&GSE on protein carbonylation index in liver from rats fed STD diets. (A) 1-DE Coomassie-stained gel (upper panel A) and 1-DE FTSC-stained gel (lower panel A) of liver proteins STD dietary groups. (B) Liver total protein carbonylation index measured in STD-CONTROL, -FOM-, -GSE-, and -FOM&GSE-fed rats. Results are means (standard deviation) (n = 5–7). * P < 0.05 vs. STD-C; &
P < 0.05 vs. STD-FOM; #
P < 0.05 vs. STD-GSE; $
P < 0.05 vs. STD-FOM&GSE. Comparisons were performed using the one-way ANOVA and Tukey post hoc tests. Images are representatives of three independent labelling experiments performed in triplicates. STD: standard diet; GSE: grape seed polyphenols extract; FOM: fish oil mixture.
