Integration of DNA damage responses with dynamic spatial genome organization

Area of Science:

• Molecular Biology
• Cell Biology
• Genetics

Background:

• Genome stability and cellular homeostasis rely on the coordinated DNA damage response (DDR).
• Emerging evidence indicates intricate crosstalk between DDR signaling and cellular processes.
• Mechanisms governing this coordination are not fully understood.

Purpose of the Study:

• To review the emerging crosstalk between DNA repair factors and various cellular processes.
• To present a framework for understanding how these dynamic processes intersect in nuclear space.
• To elucidate how this interplay preserves genome stability and cell survival.

Main Methods:

• Literature review of recent findings on DNA damage response.
• Analysis of the integration of DNA repair with chromatin remodeling, replication, transcription, and spatial genome organization.
• Examination of the role of cytoskeletal forces and liquid-liquid phase separation (LLPS) in DNA repair.

Main Results:

• DNA repair is closely integrated with chromatin remodeling, replication, transcription, and spatial genome organization.
• Cytoskeletal forces and LLPS play significant roles in mediating DNA repair.
• A dynamic interplay exists between DNA repair factors and shifting genome structures.

Conclusions:

• The coordinated interplay of multiple cellular processes is crucial for efficient DNA repair.
• This dynamic interaction ensures the assembly of DNA repair proteins to maintain genome stability.
• Understanding these mechanisms is vital for preserving cell survival.
