Abstract
Mutant cells that are defective for certain components of the mammalian DNA damage response (DDR) have been shown to display hypersensitivity to killing by ionizing radiations; these findings have prompted the idea that drugs that emulate these DDR deficiencies might serve as clinically useful radiosensitizers for improving results in cancer therapy. In this chapter, the ways in which several agents now established as radiosensitizers do in fact function by inhibiting parts of the DDR are first presented. The various subsystems of the DDR are next reviewed, and several potential molecular targets for discovery or design of chemical modifiers that could lead novel radiosensitizing drugs are discussed.
