What is the Origin of DNA Methylation Profiling?

The term is rooted in the field of epigenetics, which studies heritable phenotype changes that do not involve alterations in the DNA sequence itself. The development of array-based technologies, such as the Illumina MethylationEPIC BeadChip, has made comprehensive, reproducible profiling clinically feasible for assessing aging, disease risk, and the impact of lifestyle on gene regulation.

What is the Mechanism of DNA Methylation Profiling?

Methylation patterns regulate gene transcription; high methylation in a promoter region typically silences a gene, while low methylation permits expression. By analyzing the methylome, clinicians can identify dysregulation in critical pathways, such as estrogen metabolism or cortisol signaling, often linked to hormonal health issues. Targeted interventions, including specific B vitamins and phytochemicals, can then be employed to favorably influence these epigenetic marks and restore optimal gene function and cellular longevity.

DNA Methylation Profiling

Meaning

DNA methylation profiling is a sophisticated epigenetic diagnostic technique that measures the pattern of methyl groups attached to cytosine bases in an individual’s DNA, offering a dynamic view of gene expression and biological aging. This process is crucial because it reveals how environmental factors, lifestyle, and hormonal status are actively influencing the genome without altering the underlying DNA sequence. It provides a quantifiable biomarker for cellular health and the pace of biological aging.
