DNA Methylation News and Research

RSS

DNA methylation is a type of chemical modification of DNA that can be inherited and subsequently removed without changing the original DNA sequence. As such, it is part of the epigenetic code and is also the most well characterized epigenetic mechanism.

High-Accuracy DNA Methylation Clocks Illuminate Age-Related Changes in Primate Ovaries

The ovary is an essential organ for female fertility, and its age-dependent decline in function is a major cause of infertility.
