Some studies suggest that associations between the health of children and the experiences of their parents or grandparents may be due to epigenetic mechanisms, but confounding factors challenge this interpretation.
The concept of epigenetic inheritance has long been controversial. Some researchers hope that new data on cross-generational effects of environmental exposures will help settle the debate.
A long noncoding RNA from humans appeared to help the enzyme phenylalanine hydroxylase work better in a mouse model of phenylketonuria, the disorder characterized by reduced activity of that enzyme.
Prior to a 2019 preprint, “glycoRNAs” weren’t known to exist. Now, the researchers who found them say they’re on lots of cells and may play a role in immune signaling.
The recently discovered long noncoding RNAs seem to boost the production of specific proteins in the cell by interacting with RNA-binding proteins, researchers find.
Moderately obese men display different epigenetic marks on their sperm than lean men, and bariatric surgery in massively obese men correlated with changes in sperm methylation.
