Abstract:
Amyotrophic lateral sclerosis (ALS) is a rapidly disabling and fatal neurodegenerative disease. Due to insufficient disease-modifying treatments, there is an unmet and urgent need for elucidating disease mechanisms that occur early and represent common triggers in both familial and sporadic ALS. Emerging evidence suggests that impaired DNA damage response contributes to age-related somatic accumulation of genomic instability and can trigger or accelerate ALS pathological manifestations. In this review, we summarize and discuss recent studies indicating a direct link between DNA damage response and ALS. Further mechanistic understanding of the role genomic instability is playing in ALS disease pathophysiology will be critical for discovering new therapeutic avenues.
Insights
Impaired DNA damage response may trigger or accelerate amyotrophic lateral sclerosis (ALS). Understanding genomic instability in ALS is crucial for developing new treatments for this fatal neurodegenerative disease.
Area of Science:
- Neuroscience
- Genetics
- Molecular Biology
Background:
- Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited treatment options.
- Early disease mechanisms and common triggers in familial and sporadic ALS require elucidation.
- Genomic instability, linked to DNA damage response, is increasingly implicated in neurodegenerative diseases.
Purpose of the Study:
- To review and discuss recent evidence linking DNA damage response to ALS.
- To explore the role of genomic instability in ALS pathophysiology.
- To identify potential therapeutic avenues based on understanding disease mechanisms.
Main Methods:
- Literature review of recent studies on DNA damage response and ALS.
- Synthesis of evidence connecting genomic instability to ALS pathological manifestations.
- Discussion of mechanistic insights into DNA damage and ALS.
Main Results:
- Emerging evidence directly links impaired DNA damage response to ALS.
- Genomic instability may act as an early trigger or accelerator of ALS.
- Age-related somatic accumulation of DNA damage contributes to neurodegeneration.
Conclusions:
- Understanding the role of genomic instability in ALS is critical.
- Targeting DNA damage response pathways may offer new therapeutic strategies for ALS.
- Further research into the mechanistic link between DNA damage and ALS is warranted.

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...
