Abstract:
Defects in the DNA damage response often lead to an increased susceptibility to cancer, and so the DDR presents an interesting set of novel therapeutic targets. The maintenance of genomic integrity by the DDR has also been found to be involved in the process of organismal ageing. While the removal of cells containing damaged DNA can be beneficial in the prevention of cancer, it may contribute to both normal and pathological ageing.
Insights
Defects in the DNA damage response (DDR) increase cancer risk and impact aging. Targeting DDR pathways offers new therapeutic strategies for cancer and age-related diseases.
Area of Science:
- Genetics and Molecular Biology
- Cancer Research
- Aging Research
Background:
- The DNA damage response (DDR) is crucial for maintaining genomic stability.
- Defects in DDR are linked to increased cancer susceptibility.
- DDR also plays a role in organismal aging processes.
Purpose of the Study:
- To explore the dual role of the DDR in cancer and aging.
- To identify the DDR as a potential therapeutic target for both cancer and aging.
Main Methods:
- Review of existing literature on DDR mechanisms.
- Analysis of studies linking DDR to cancer development.
- Investigation of DDR's involvement in cellular senescence and organismal aging.
Main Results:
- DDR defects significantly elevate cancer risk.
- DDR is implicated in the mechanisms of normal and pathological aging.
- Cellular removal of damaged DNA, a DDR function, impacts aging.
Conclusions:
- The DDR is a critical regulator of both cancer prevention and aging.
- Therapeutic strategies targeting the DDR could address both cancer and age-related conditions.

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...
