[DNA protective activity of natural and synthetic antioxidants]
Abstract:
Free radicals attack cell genome in oxidative stress conditions accompanying many human diseases. Mutagenic and carcinogenic xenobiotics cause oxidative DNA damages also. Oxidative DNA damages become intensive in aging organisms. The data on natural and synthetic antioxidants protecting DNA from oxidation are presented in this review.
Insights
Oxidative stress and harmful chemicals damage DNA, especially in aging. This review covers natural and synthetic antioxidants that protect DNA from this damage.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Context:
- Oxidative stress is implicated in numerous human diseases.
- Exposure to mutagenic and carcinogenic xenobiotics contributes to DNA damage.
- DNA oxidation intensifies with organismal aging.
Purpose:
- To review natural and synthetic antioxidants.
- To discuss their protective mechanisms against DNA oxidation.
Summary:
- Free radicals and xenobiotics induce oxidative DNA damage.
- This damage is exacerbated in aging populations.
- Antioxidants offer potential protection against these damaging processes.
Impact:
- Understanding antioxidant functions is crucial for disease prevention and treatment.
- Highlights the role of antioxidants in mitigating age-related DNA damage.
- Provides a data-driven overview of protective compounds for DNA integrity.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
