The base excision repair (BER) pathway is crucial for genomic stability and impacts cancer treatment effectiveness. BER gene expression levels can predict cancer risk, progression, and patient outcomes, offering new therapeutic targets.
Area of Science:
- Genomics
- Cancer Biology
- Molecular Oncology
Background:
- The base excision repair (BER) pathway is essential for maintaining genomic stability.
- Genetic factors significantly influence cancer patient responses to therapy and overall prognosis.
- BER pathway components play a critical role in cancer development and progression.
Purpose of the Study:
- To review the role of the BER pathway in advanced cancer therapies.
- To investigate the association between BER gene polymorphisms/expression and cancer outcomes.
- To explore the potential of BER as a target for cancer diagnosis and personalized treatment.
Main Methods:
- Literature review focusing on BER pathway genes (OGG1, XRCC1, APE1, Polβ).
- Analysis of studies examining polymorphisms and expression levels of key BER genes.
- Correlation of BER factor levels with cancer risk, progression, and treatment response.
Main Results:
- BER gene expression levels are closely linked to cancer risk, progression, and prognosis across various cancer types (breast, colon, lung, bladder).
- BER factors significantly affect the efficacy of chemotherapy and radiation therapy.
- Specific BER genes (OGG1, XRCC1, APE1, Polβ) show potential as predictive biomarkers.
Conclusions:
- The BER pathway is a promising target for improving cancer diagnosis and prognostic prediction.
- Targeting BER proteins could lead to the development of novel, personalized cancer therapies.
- Further large-scale prospective studies are needed to fully leverage BER pathway insights for clinical application.

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...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
