DNA Damage Response

Module 2

The DNA Damage Response (DDR) pathway coordinates the identification, signalling, and repair of DNA damage caused by endogenous or exogenous factors [1]. It also integrates the regulation of cell cycle progression with DNA repair to minimize the chance of DNA damage being permanently passed on through cell division [1]. Severe DNA damage that cannot be repaired may trigger apoptosis; as such the DDR pathway is of crucial importance as a cancer target.
