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.

New Aging Clock Links Intrinsic Capacity to Immune Health and Longevity

A team of international researchers has developed a new biological age "clock" that estimates how well someone is aging, not just how "old" they or their various organs might be.

Genetic Mutations May Be Behind Epigenetic Clock of Aging

Researchers at University of California San Diego School of Medicine have published results that shed new light on an old question: what causes aging at the molecular level? Their findings, published in Nature Aging, describe a never-before-seen link between the two most accepted explanations: random genetic mutations and predictable epigenetic modifications.

Epigenetic Mechanism Controls Placental Blood Vessel Formation

If the development of blood vessels in the placenta is impaired, fetal growth retardation may result. Scientists from the German Cancer Research Center (DKFZ) and the Mannheim Medical Faculty of Heidelberg University discovered that the correct development of functioning blood vessels in the mouse placenta is controlled epigenetically: One of the enzymes that modify gene activity using methyl groups is responsible.
