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.

One gram of omega-3 per day may slow down the rate of biological aging

A clinical trial reveals that omega-3, vitamin D, and exercise can slow biological aging, with combined interventions showing the strongest effects on health.

Maternal vitamin D deficiency may accelerate fetal aging and impact newborn health

Maternal vitamin D deficiency during pregnancy is linked to accelerated epigenetic gestational age in infants at birth, suggesting improper fetal development influenced by low vitamin D levels. The study also found associations between maternal age, birth height, and epigenetic aging, though cord blood vitamin D showed no significant impact.

Breakthrough study links genetic mutations to epigenetic changes in 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.

Mouse protein disrupts cancer-causing epigenetic changes in human colorectal cancer

A little-known mouse protein disrupts cancer-causing chemical changes to genes associated with human colorectal cancer cells and potentially could be used to treat solid tumors, according to a new study from researchers at the Johns Hopkins Kimmel Cancer Center and the Chinese Academy of Sciences.

Study links epigenetic mechanism to placental blood vessel development

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.
