Dietary Compounds as Epigenetic Modulating Agents in Cancer

Area of Science:

• Epigenetics
• Nutritional Biochemistry
• Cancer Biology

Background:

• Epigenetic mechanisms regulate gene expression, and their dysregulation is linked to diseases like cancer.
• Natural phytochemicals, abundant in fruits, vegetables, and supplements, can influence the epigenome.
• These compounds possess antioxidant and anti-carcinogenic properties.

Purpose of the Study:

• To review the role of dietary phytochemicals in restoring aberrant epigenetic alterations in cancer cells.
• To focus on DNA methylation and histone modifications as key epigenetic targets.
• To discuss the mechanisms and molecular targets of phytochemicals in various cancers.

Main Methods:

• Literature review of studies on phytochemicals and epigenetics in cancer.
• Analysis of phytochemicals' effects on DNA methylation and histone modifications.
• Discussion of molecular mechanisms and cancer-specific targets.

Main Results:

• Specific phytochemicals (e.g., catechins, curcumin, genistein, quercetin, resveratrol) reverse epigenetic alterations.
• These compounds modulate gene expression by targeting epigenetic machinery.
• Phytochemicals demonstrate anti-tumor activity by affecting oncogenes and tumor suppressor genes.

Conclusions:

• Dietary phytochemicals offer a potential strategy for cancer prevention and therapy.
• Modulating epigenetic activities with phytochemicals can lead to novel cancer biomarkers.
• Phytochemicals represent a promising alternative therapeutic approach in oncology.
