DNA repair meets the RNA world

Area of Science:

• Biochemistry
• Molecular Biology
• Genetics

Background:

• Genome stability and DNA repair are essential for species survival and evolutionarily conserved.
• Emerging evidence highlights a significant connection between RNA processing and DNA repair pathways.
• The apurinic/apyrimidinic endonuclease 1 (APE1), a base excision repair enzyme, interacts with RNA processing molecules.

Purpose of the Study:

• To provide an up-to-date overview of DNA repair mechanisms, particularly base excision repair (BER).
• To explore the intricate links between RNA processing and DNA repair pathways.
• To discuss the implications of these interactions for understanding physiology, disease, and developing therapeutic interventions.

Main Methods:

• Review of current scientific literature on DNA repair and RNA metabolism.
• Analysis of experimental evidence linking specific DNA repair enzymes (e.g., APE1) with RNA processing.
• Synthesis of findings from five expert reviews within the Forum.

Main Results:

• Noncoding RNA expression is altered by DNA damage and can influence genes involved in genome stability.
• DNA repair enzymes, like APE1, exhibit dual roles in both DNA repair and RNA processing.
• The interaction between DNA repair and RNA metabolism is complex and multifaceted.

Conclusions:

• The convergence of DNA repair and RNA processing pathways is critical for maintaining genome stability.
• Understanding these interactions opens avenues for novel therapeutic strategies targeting diseases associated with genomic instability.
• Further in vivo research is needed to fully elucidate the physiological and pathological relevance of the DNA repair-RNA metabolism nexus.
