MicroRNAs and DNA damage response: implications for cancer therapy
1Howard Hughes Medical Institute, Human Biology and Public Health Sciences Divisions, Fred Hutchinson Cancer Research Center, Seattle, WA, USA.
MicroRNAs (miRNAs) regulate DNA damage response (DDR) pathways, impacting genome stability and sensitivity to DNA damaging agents. This review explores miRNA roles in DDR, DNA repair, and their therapeutic potential in cancer.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- The DNA damage response (DDR) is crucial for maintaining genomic integrity.
- Dysfunctional DDR leads to genomic instability and increased sensitivity to DNA-damaging agents.
- MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
Purpose of the Study:
- To review the emerging roles of miRNAs in regulating DDR and DNA repair pathways.
- To discuss the implications of miRNAs in cellular sensitivity to DNA damaging agents.
- To explore the potential of miRNAs as therapeutic targets in cancer treatment.
Main Methods:
- Literature review of recent findings on miRNAs and DDR.
- Analysis of miRNA involvement in DNA repair mechanisms.
- Discussion of miRNA-mediated regulation in cancer therapy.
Main Results:
- Specific miRNAs (e.g., miR-24, 138, 96, 182) are implicated in DDR and DNA repair.
- Altered miRNA expression affects cellular responses to DNA damage.
- miRNAs play a significant role in modulating genomic stability.
Conclusions:
- miRNAs are key regulators of the DNA damage response and repair.
- miRNAs influence cellular sensitivity to genotoxic stress.
- Targeting miRNAs offers promising avenues for novel cancer therapies.

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...
