Upside-down world: DNA protecting protein helps cancer drug to kill cells
Some DNA repair enzymes can become double-edged swords - If they work too slowly, they can block necessary cell maintenance and contribute to cell death. This could explain the somewhat mysterious success of the widely used ...

Scientists identify key decision-point at which cells with broken DNA repair themselves or die
When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.
