Base excision repair (BER) is crucial for fixing DNA damage in cancer. Targeting BER offers new therapeutic strategies for cancer treatment by exploiting DNA repair pathways.
Area of Science:
- Molecular Biology
- Cancer Research
- Genetics
Background:
- Base excision repair (BER) is a critical DNA repair pathway.
- BER addresses mutagenic and genotoxic DNA base lesions, implicated in cancer etiology and treatment.
- Oxidative lesions and deamination products are significant mutational signatures in cancer.
Purpose of the Study:
- To explore the relevance of BER in cancer chemotherapy.
- To discuss potential treatment strategies involving BER.
- To summarize progress in developing inhibitors for BER-related factors.
Main Methods:
- Review of current literature on BER in cancer.
- Analysis of therapeutic strategies targeting BER.
- Summary of inhibitor development for BER proteins.
Main Results:
- BER plays a role in cancer cell survival under stress and therapeutic intervention.
- Synthetic lethality approaches targeting BER are emerging.
- Inhibitors for core BER proteins and related factors are under development.
Conclusions:
- BER is a promising target for novel cancer therapies.
- Targeting BER can be achieved through multiple strategies, including synthetic lethality.
- Further development of BER inhibitors holds potential for cancer treatment.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
