DNA damage-inducing endogenous and exogenous factors and research progress

Area of Science:

• Environmental Science
• Life Science
• Toxicology
• Molecular Biology

Background:

• DNA damage from exogenous and endogenous factors is linked to cancer, neurodegenerative diseases, and aging.
• Prolonged exposure to DNA damage-inducing factors can result in severe, hard-to-treat diseases.
• A comprehensive summary of these factors is lacking, hindering mechanistic research and disease prevention.

Purpose of the Study:

• To summarize representative exogenous DNA damage-inducing factors.
• To explore the types of DNA damage caused by these factors.
• To integrate environmental and life science perspectives for understanding disease mechanisms and prevention.

Main Methods:

• Literature search to identify and select 14 representative carcinogenic exogenous DNA damage-inducing factors.
• Inclusion of both exogenous and endogenous DNA damage factors in the review.
• Analysis of the types of DNA damage induced by the identified factors.

Main Results:

• Identification and summary of 14 key exogenous DNA damage-inducing factors.
• Categorization of DNA damage types associated with these factors.
• Discussion of the interplay between environmental sources and biological consequences.

Conclusions:

• Understanding DNA damage-inducing factors is crucial for cancer, aging, and neurodegenerative disease research.
• A combined environmental and life science approach is necessary for effective mechanistic studies and prevention strategies.
• This review provides a foundational summary of key factors and their associated DNA damage.
