DNA can be damaged by different environmental insults, such as ultraviolet light, ionizing radiation, oxidative stress or certain drugs. If the DNA is not repaired, cells may begin growing uncontrollably, leading to the development of cancer. Therefore, cells must maintain an intricate regulatory network to ensure that their DNA remains intact. Researchers have discovered a novel mechanism that controls a cell's response to DNA damage.
