XRCC3 Depletion Induces Spontaneous DNA Breaks and p53-Dependent Cell Death

In vertebrate cells, Xrcc3 initiates the repair of exogenous induced-DNA breaks during S and G2/M phases of the cell cycle by homologous recombination. However, much less is known of the role of Xrcc3 in the response to spontaneous DNA breaks. Using a siRNA approach, we show that depletion of XRCC3...
