Fundamental epigenetic process utilizing folate for gene regulation through methylation.
A biochemical process by which folate, serving as a methyl group carrier cofactor, participates in DNA and protein methylation, regulating gene expression.
Folate plays a central role as a methyl group donor in the cellular methylation cycle. Through the tetrahydrofolate (THF) coenzyme, it provides the necessary carbon units to synthesize S-adenosylmethionine (SAM), the primary methyl donor in the body. This DNA methylation reaction modifies gene expression without altering the DNA sequence, affecting transcription. Folate deficiency alters this process, affecting genomic stability and embryonic development. Optimal folate intake is crucial to maintain balanced epigenetics.
Supply of methyl groups for DNA and protein methylation, regulating gene expression and genomic stability.
Ensure a daily intake of 400 to 600 µg of dietary folate from green vegetables and legumes. Women of childbearing age should consume more, particularly pre-conception. Folate supplements may be recommended in cases of increased need or malabsorption.
Adequate folate intake is essential to support gene regulation mechanisms.
