Again, no difference was observed in the number of γH2AX/53BP1 foci at 1 h post‐3 Gy between CRPC and HSPC biopsies; however, tumor biopsies from CRPC patients showed a distinct increase at 24 h for both γH2AX and 53BP1 markers upon pretreatment with olaparib (Fig. S3A,B). The gene discussed is TP53BP1; the disease is neoplasm.
