Lysosomal redox-active iron is important for oxidative stress-induced DNA
damage.

Data show that specifically chelating lysosomal redox-active iron can prevent
most H(2)O(2)-induced DNA damage. Lysosomes seem to contain the major pool of
redox-active labile iron within the cell. Under oxidative stress conditions,
this iron may then relocate to the nucleus and play an important role for DNA
damage by taking part in Fenton reactions.
