What is the Origin of Methylation Data?

This data originates from the field of epigenetics, utilizing advanced molecular techniques like the Illumina Methylation Array or whole-genome bisulfite sequencing. The concept of using methylation patterns to calculate a "biological clock," such as the Horvath clock, has established this data as a critical tool in longevity research.

What is the Mechanism of Methylation Data?

The data reflects the activity of the cellular machinery responsible for adding or removing methyl groups, which determines whether a gene is actively transcribed or silenced. Aberrant methylation patterns can lead to inappropriate gene expression, contributing to disease pathology and accelerated aging. By analyzing the data, clinicians can identify specific nutrient deficiencies or genetic polymorphisms that impair optimal methyl group transfer.

Methylation Data

Meaning

Quantitative biological information derived from the analysis of DNA methylation patterns, specifically the addition of a methyl group to cytosine bases, which is a key epigenetic mark regulating gene expression. This data provides a crucial snapshot of biological age, environmental exposure, and the functional status of metabolic pathways, such as the folate and methionine cycles. Clinically, it is used as a powerful biomarker to guide personalized nutritional and lifestyle interventions.
