FACS read out in CH cells treated with 24 hours of NU6027 is shown here (A).

<p><b>B.</b> Quantification of various phases of the cell cycle is shown for CH cell treated with NU6027. Data represent mean values ±SEM (n = 6). Results were analysed using Students t-test. * p<0.05. <b>C.</b> FITC-Annexin V apoptosis assay is shown here. The proportion of cells in early phase apoptosis is higher in XRCC1 deficient cells treated with NU6027 compared to wild type cells.
