Flavonoids as Epigenetic Modulators for Prostate Cancer Prevention

Area of Science:

• Oncology
• Nutritional Science
• Epigenetics

Background:

• Prostate cancer (PCa) is a prevalent, multifactorial disease with an unclear etiology, making it a target for chemoprevention.
• Dietary flavonoids, known for various health benefits, have demonstrated anti-carcinogenic properties.
• Epigenetic alterations are crucial in cancer initiation and progression.

Purpose of the Study:

• To review recent evidence on the antitumoral effects of dietary flavonoids in PCa.
• To focus on the epigenetic mechanisms through which flavonoids exert their effects in PCa.
• To explore the potential of flavonoids as epigenetic modulators for PCa chemoprevention and treatment.

Main Methods:

• Literature review of recent studies on dietary flavonoids and prostate cancer.
• Analysis of evidence regarding the epigenetic actions of flavonoids, including DNA methylation and histone modification.
• Examination of the impact of flavonoids on oncogenes, tumor suppressor genes, miRNA, and lncRNA.

Main Results:

• Dietary flavonoids exhibit antitumoral effects against PCa.
• Flavonoids can reverse epigenetic aberrations, including DNA methylation changes, that promote neoplastic transformation.
• Flavonoids modulate epigenetic enzymes like DNA methyltransferase (DNMT), histone acetyltransferase (HAT), and histone deacetylase (HDAC).
• Flavonoids can restore altered miRNA and lncRNA expression patterns observed in PCa.

Conclusions:

• Dietary flavonoids possess significant potential for PCa chemoprevention and treatment through epigenetic modulation.
• Targeting epigenetic mechanisms with flavonoids offers a promising strategy to inhibit carcinogenesis.
• Further optimization of flavonoid use could lead to effective natural therapies for PCa and other cancers.
