We tested this prediction by monitoring RAD51 foci formation after the exposure of A549 non-small cell lung carcinoma (NSCLC) cells to ionizing radiation (IR), using a robust cell-based assay based on high-content microscopy with the Cellomics ArrayScan VTI, to objectively enumerate RAD51 foci (Jeyasekharan et al., 2013). This evidence concerns the gene RAD51 and non-small cell lung carcinoma.
