DNA double-strand breaks (DSBs) can be generated by a variety of genotoxic agents, including ionizing radiation and radiomimetic chemicals. They can also occur when DNA replication complexes encounter other forms of DNA damage, and are produced as intermediates during certain site-specific recombination processes. It is crucial that cells recognize DSBs and bring about their efficient repair, because a single unrepaired cellular DSB can induce cell death, and defective DSB repair can lead to mutations or the loss of significant segments of chromosomal material. Eukaryotic cells have evolved a variety of systems to detect DNA DSBs, repair them, and signal their presence to the transcription, cell cycle and apoptotic machineries. In this review, I describe how work on mammalian cells and also on model organisms such as yeasts has revealed that such systems are highly conserved throughout evolution, and has provided insights into the molecular mechanisms by which DNA DSBs are recognized, signalled and repaired. I also explain how defects in the proteins that function in these pathways are associated with a variety of human pathological states.
