Effect of PAW-rocket salad extract on cellular redox homeostasis. Caco2 cells were treated for 5 h with increasing concentrations of polyphenols (0.01–100 mg/mL) extracted from PAW-20 (white bar) or UT (gray bar) rocket salad. (a) Intracellular ROS production was determined by DCFDA ROS Assay Kit (Abcam). (b) Intracellular NO production was determined by the Nitric Oxide Assay (Abcam). Control represents Caco2 cells incubated with culture medium containing 0.1% DMSO. Data are presented as the mean ± SD of relative percentage of control sample (set at 100%) obtained from two independent experiments, each carried out in quadruplicate. Statistical significance was calculated by pairwise multiple comparisons for one-way ANOVA followed by Tukey’s HSD post hoc test. **: significant difference versus control p < 0.01; different letters, when reported, mean significant difference between groups (PAW-20 versus UT at different concentrations), p < 0.05.
