DNA damage-inducing endogenous and exogenous factors and research progress.

Abstract

The substances that cause abnormal DNA structures are known as DNA damage-inducing factors, and their resulting DNA damage has been extensively studied and proven to be closely related to cancer, neurodegenerative diseases, and aging. Prolonged exposure to DNA damage-inducing factors can lead to a variety of difficult-to-treat diseases, yet these factors have not been well summarized. It is crucial to use a combination of environmental science and life science to gain a deep understanding of the environmental sources and biological consequences of DNA damage-inducing factors for mechanistic research and prevention of diseases such as cancer. This article selected 14 representative carcinogenic exogenous DNA damage-inducing factors and summarized them through a literature search, including both exogenous and endogenous DNA damage factors, and explored the types of DNA damage caused by the relevant damage factors.
