Effect of GdBNs on DSBs formation and repair in irradiated (4 Gy) U87 cells. Distribution of DSBs foci in U87 cells never incubated with GdBNs (a) and incubated with 1 mM GdBNs for 1 h (b). Non-irradiated controls (NI) are also compared. The respective maximum images of representative nuclei for each period of time PI are shown above: γH2AX—green, 53BP1—red, chromatin—artificially blue
