Interplay Between the Cytoskeleton and DNA Damage Response in Cancer Progression

Area of Science:

• Cell Biology
• Cancer Research
• Molecular Oncology

Background:

• DNA damage is a key driver of cancer development and progression.
• DNA damage response (DDR) pathways dictate cell fate after DNA damage, either promoting repair or cell death.
• Cytoskeletal dynamics are increasingly recognized as critical regulators of DDR pathway function.

Purpose of the Study:

• To review the intricate roles of cytoskeletal proteins in DNA damage response pathways within cancer cells.
• To highlight the often-overlooked involvement of the cytoskeleton in DDR and its implications for cancer therapy.
• To explore the potential of combining cytoskeleton-targeting agents with DDR inhibitors for improved cancer treatment.

Main Methods:

• Literature review of existing research on cytoskeleton and DNA damage response.
• Analysis of the involvement of microfilaments, intermediate filaments, and microtubules in DDR pathways.
• Discussion of specific DDR pathways including non-homologous end joining (NHEJ), homologous recombination (HR), base excision repair (BER), and nucleotide excision repair (NER).

Main Results:

• Cytoskeletal proteins are integral to DDR, involved in recruiting repair molecules and facilitating DNA mobility.
• The cytoskeleton influences the efficacy of various DDR pathways critical for cancer cell survival.
• The interplay between cytoskeleton and DDR is crucial for determining cancer cell fate following DNA damage induction.

Conclusions:

• The cytoskeleton's role in DDR is essential but frequently neglected in cancer research and therapeutic strategies.
• Exploiting the cytoskeleton-DDR axis offers novel avenues for developing more effective cancer therapies.
• Synergistic strategies combining DDR inhibitors and cytoskeleton-targeting agents hold promise for cancer treatment.
