Severity of ischemia/reperfusion injury accompanied with generation of reactive oxygen species is reduced by hypoxic preconditioning, the precise mechanisms of which are not completely understood. We found that cobalt-induced hypoxia-inducible factor-1α activity ameliorated suppression of cell growth caused by H2O2 through protecting mitochondrial DNA from oxidative damage.
