DNA damage sensing proteins

Issue Image

In contrast to biophysical predictions, this image illustrates that "DNA damage sensing proteins" (green signal) form foci along primary cosmic rays in a regular self-excluding manner (see Costes et al, e155). Upper panel: the white dashed arrow indicates the traversal of one Fe particle in a human cell (DNA shown in blue). Middle panel: the relative position of foci (green spheres) is shown with respect to the DNA dye intensity profile visualized by a three-dimensional topographic surface. Lower panel: foci preferentially locate within low DNA nuclear density regions, or at the interface between high and low nuclear DNA densities.
