Abstract:
Radiotherapy (RT) is one of the main cancer treatments and grows in importance due to improved techniques. DNA damage caused by ionizing radiation creates DNA strand breaks that trigger an intervention of DNA repair pathways involving numerous proteins and enzymes. In recent years, we have identified DNA repair inhibitors as targets for inhibiting cellular repair systems and thus causing cell death. Combining RT with these DNA repair inhibitors appears to be a new approach for cancer treatment, but safety and real efficiency of this combination in practice is unclear. Numerous trials are underway in various diseases and initial results are promising overall, yet remain controversial.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
