Malondialdehyde concentrations in Caco-2/15 cells challenged with iron/ascorbate and/or Trolox.

<p>Caco-2/15 cells were exposed to Fe/Asc (200 µM/2 mM) and Trolox (0.25 mM) for 6 h at 37°C and/or with 5-AZA (10 µM). Oxidative stress was assessed by measuring MDA as an index of lipid peroxidation. Values are means ± SEM for three independent experiments. ***P<0.001 vs. controls; ^###P<0.001 vs. Fe/Asc.
