Vitamin C and epigenetics: A short physiological overview

Area of Science:

• Biochemistry
• Epigenetics
• Nutritional Science

Background:

• Ascorbic acid (vitamin C) is crucial for tissue homeostasis.
• Epigenetic modifications are increasingly recognized for their role in disease.
• Understanding vitamin C's epigenetic functions is an area of active research.

Purpose of the Study:

• To review the known and emerging functions of ascorbic acid in epigenetic control.
• To elucidate the mechanisms by which vitamin C influences DNA and histone modifications.
• To explore the potential implications of vitamin C in epigenetic regulation.

Main Methods:

• Literature review of biochemical and molecular studies.
• Analysis of ascorbic acid's role as a cofactor in enzymatic reactions.
• Discussion of the interplay between environmental factors, vitamin C, and the genome.

Main Results:

• Ascorbic acid acts as a cofactor for ten-eleven translocation (TET) dioxygenases involved in DNA demethylation.
• Vitamin C is essential for histone demethylation, serving as a cofactor for Jumonji C-domain-containing demethylases.
• Vitamin C appears to bridge environmental signals and genomic responses.

Conclusions:

• Ascorbic acid plays a significant role in epigenetic regulation through its cofactor functions.
• Further research is needed to fully determine the precise mechanisms of vitamin C in epigenetic control.
• Vitamin C holds potential implications for understanding and managing diseases influenced by epigenetic alterations.
