Natural Compounds: Role in Reversal of Epigenetic Changes

Area of Science:

• Cancer epigenetics and molecular oncology.
• Natural product chemistry and pharmacology.

Background:

• Carcinogenesis involves genetic and epigenetic alterations, impacting gene expression and genome stability.
• Epigenetic regulation (DNA methylation, histone modification, microRNA) is crucial in cancer cell metabolism and phenotype.
• Natural compounds are emerging as agents targeting epigenetic mechanisms for cancer prevention and treatment.

Purpose of the Study:

• To review the potential of natural chemopreventive agents in reversing cancer-related epigenetic aberrations.
• To summarize how these agents regulate key epigenetic enzymes and microRNAs.
• To highlight the need for novel chemopreventive strategies in cancer therapy.

Main Methods:

• Literature review of studies on natural compounds and epigenetic modifications in cancer.
• Analysis of mechanisms involving histone deacetylases (HDACs), histone acetyltransferases (HATs), DNA methyltransferase I (DNMT1), and microRNAs (miRNAs).
• Synthesis of findings on the chemopreventive and therapeutic potential of natural agents.

Main Results:

• Natural compounds can modulate the activity of HDACs, HATs, DNMT1, and miRNAs, thereby reversing epigenetic alterations.
• These agents demonstrate anticarcinogenic potential by targeting key epigenetic regulators.
• Evidence supports the role of natural compounds in cancer cell metabolism regulation.

Conclusions:

• Natural chemopreventive agents offer a promising avenue for reversing cancer-related epigenetic changes.
• Targeting epigenetic mechanisms with natural compounds represents a viable molecular approach for cancer treatment.
• Further research into novel and combination therapies involving natural agents is warranted to enhance cancer treatment efficacy.
