FIG. 6.

Effect of plant compounds on protein synthesis levels in Stx2-treated Vero-d2EGFP cells. Protein synthesis in Vero-d2EGFP cells was measured after a 2-h coincubation with plant polyphenolic compounds and Stx2. Cells were coincubated with no plant compound, 1 mg/ml of caffeic acid, 1 mg/ml of red wine concentrate, 0.5 mg/ml of grape pomace extract, or 0.1 mg/ml of grape seed extract. The means ± standard errors of the means of at least four independent experiments with triplicate samples for each condition are shown.
