The functional regulation between extracellular vesicles and the DNA damage responses

Area of Science:

• Molecular Biology
• Cell Biology
• Biochemistry

Background:

• The DNA damage response (DDR) is vital for organism survival, and its dysregulation is linked to diseases, particularly cancer.
• Extracellular vesicles (EVs) are key mediators of intercellular communication, gaining significant research attention.
• Emerging evidence highlights a critical interplay between DDR and EVs.

Purpose of the Study:

• To review the current understanding of the inter-regulatory relationship between EVs and DDR.
• To emphasize the impact of EVs from various sources on recipient cell DDR.
• To discuss the potential applications of EVs in research and cancer therapy.

Main Methods:

• Literature review focusing on studies investigating the connection between EVs and DDR.
• Analysis of how DNA damage influences EV release and content.
• Examination of how EVs modulate DDR in both originating and target cells.

Main Results:

• DNA damage affects the release and composition of EVs.
• EVs play a dual role in modulating DDR, influencing cell survival or death.
• EVs from different sources exert varied effects on recipient cell DDR.

Conclusions:

• EVs are significant players in the DDR pathway, influencing cellular fate.
• Understanding the EV-DDR axis offers promising avenues for cancer research and treatment.
• EVs hold potential as diagnostic biomarkers and therapeutic agents in oncology.
