Figure 1. Effects of iron/ascorbate and 5-Aza-2′-deoxycytidine on cell viability in Caco-2/15 cells.

Caco-2/15 cells were incubated with Fe/Asc (200 µM/2 mM) and Trolox (0.25 mM) for 6 h at 37°C and/or with 5-AZA (10 µM) as described in Materials and Methods, Cellular viability was assessed by MTT. Results represent the means ± SEM of n = 3 independent experiments.
