Epigenetic Clock: DNA Methylation in Aging

الملخص EN

Aging, which is accompanied by decreased organ function and increased disease incidence, limits human lifespan and has attracted investigators for thousands of years.

In recent decades, with the rapid development of biology, scientists have shown that epigenetic modifications, especially DNA methylation, are key regulators involved in this process.

Regular fluctuations in global DNA methylation levels have been shown to accurately estimate biological age and disease prognosis.

In this review, we discuss recent findings regarding the relationship between variations in DNA methylation level patterns and aging.

In addition, we introduce the known mechanisms by which DNA methylation regulators affect aging and related diseases.

As more studies uncover the mechanisms by which DNA methylation regulates aging, antiaging interventions and treatments for related diseases may be developed that enable human life extension.
