Deuterium Incorporation Protects Cells from Oxidative Damage

Figure 6

The effect of D-dG incorporation on the repair rate of DNA single-strand breaks induced by hydrogen peroxide in Jurkat cells. Control or D-dG pretreated cells were incubated for 30 min with 50 μM H₂O₂ and then allowed to repair. DNA breaks were measured either immediately after treatment or after different times of repair. Each point is the mean of experimental values obtained in five separate determinations. Linear regression lines are shown.
