Polyphenols: Major regulators of key components of DNA damage response in cancer

Area of Science:

• Molecular Biology
• Biochemistry
• Plant Science

Background:

• DNA damage poses a constant threat to genome stability.
• The DNA damage response (DDR) is a complex network crucial for maintaining genomic integrity.
• Polyphenols are diverse plant metabolites found in common foods and beverages.

Purpose of the Study:

• To review how polyphenolic compounds interact with the DNA damage response (DDR) pathway.
• To discuss the role of polyphenols in modulating DDR sensors, transducers, and mediators.
• To examine the influence of polyphenols on apoptosis in response to DNA damage in cancer.

Main Methods:

• Literature review of studies on polyphenols and DNA damage response.
• Analysis of chemical structures and classifications of polyphenols (phenolic acids, flavonoids, non-flavonoids).
• Synthesis of findings regarding polyphenol modulation of DDR components and apoptosis.

Main Results:

• Polyphenols can influence key components of the DDR network.
• Specific polyphenols may enhance or interfere with DNA repair mechanisms.
• Polyphenols exhibit varying effects on apoptosis induction in cancer cells under DNA-damaging conditions.

Conclusions:

• Polyphenols represent a potential class of compounds for modulating cancer cell responses to DNA damage.
• Understanding polyphenol-DDR interactions could inform novel therapeutic strategies.
• Further research is warranted to elucidate the precise mechanisms of polyphenol action in cancer therapy.
