The interface between transcription and mechanisms maintaining genome integrity

Area of Science:

• Molecular Biology
• Genetics
• Cell Biology

Background:

• Genome integrity is essential for proper gene expression.
• Transcription, the process of reading genes, can compromise genome stability.
• Cells possess mechanisms to mitigate the destabilizing effects of transcription.

Purpose of the Study:

• To review the interplay between eukaryotic RNA polymerase II transcription and genome stability.
• To summarize how transcription influences DNA repair, recombination, and replication.
• To outline how these DNA processes affect transcription.

Main Methods:

• Literature review of current research on transcription and genome stability.
• Synthesis of findings on the bidirectional relationship between transcription and DNA-related processes.

Main Results:

• Transcription impacts DNA repair, recombination, and replication by influencing DNA accessibility and processing.
• DNA repair, recombination, and replication can modulate transcription activity and fidelity.
• Specific mechanisms highlight the dynamic crosstalk between transcription and genome maintenance.

Conclusions:

• Eukaryotic transcription and genome stability are intricately linked through various molecular mechanisms.
• Understanding this crosstalk is crucial for comprehending gene regulation and preventing genomic instability.
• Further research is needed to fully elucidate the complex interactions between transcription and DNA dynamics.
