Abstract:
The human diet contributes significantly to the initiation and promotion of carcinogenesis. It has become clear that the human diet contains several groups of natural foodborne chemicals that are at least in part responsible for the genotoxic, mutagenic, and carcinogenic potential of certain foodstuffs. Electrophilic chemicals are prone to attack nucleophilic sites in DNA, resulting in the formation of altered nucleobases, also known as DNA adducts. Since DNA adduct formation is believed to signal the onset of chemically induced carcinogenesis, the DNA adduct-inducing potential of certain foodstuffs has been investigated to gain more insight into diet-related pathways of carcinogenesis. Many studies have investigated diet-related DNA adduct formation. This review summarizes work on known or suspected dietary carcinogens and the role of DNA adduct formation in hypothesized carcinogenesis pathways.
Insights
Dietary chemicals can cause cancer by damaging DNA. This review examines foodborne carcinogens and their role in DNA adduct formation, a key step in cancer development.
Area of Science:
- Nutrition and Cancer Research
- Molecular Toxicology
- Carcinogenesis Studies
Background:
- The human diet contains natural foodborne chemicals with genotoxic and carcinogenic potential.
- Electrophilic chemicals in food can interact with DNA, forming DNA adducts.
- DNA adduct formation is a critical early event in chemically induced carcinogenesis.
Purpose of the Study:
- To review known or suspected dietary carcinogens.
- To explore the role of DNA adduct formation in diet-related carcinogenesis pathways.
- To provide insight into the mechanisms by which diet influences cancer development.
Main Methods:
- Literature review of studies on diet-related DNA adduct formation.
- Analysis of research on known or suspected dietary carcinogens.
- Synthesis of findings on the link between foodborne chemicals, DNA adducts, and cancer.
Main Results:
- Numerous foodborne chemicals possess genotoxic and carcinogenic properties.
- DNA adduct formation is a well-established mechanism linking dietary factors to cancer initiation.
- Specific foodstuffs contain compounds that induce DNA damage, contributing to carcinogenesis.
Conclusions:
- Diet plays a significant role in cancer initiation and promotion.
- Understanding DNA adduct formation is crucial for identifying diet-related cancer risks.
- Further research into dietary carcinogens and their molecular targets is warranted.

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...
