E9 or MV5 cells (0.5 × 106 cells/ml) were treated with 0.1 mm BSO for 15 hr and then were incubated with or without 30 μm Fe-NTA and the indicated additions for 12 hr. Levels of ATP were determined as described in Materials and Methods. Results represent the mean ± standard error of 4–12 experiments.
