Does Human Epigenetic Inheritance Deserve a Closer Look?
Catherine Offord | Apr 4, 2022
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.

DNA Methylation Influences Replication and Genome Organization
Abby Olena | Sep 22, 2021
A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication.

Yeast “Mini Labs” Help Researchers Probe Histone Modifications
Amanda Heidt | Sep 1, 2021
By harnessing a unique property of yeast, scientists can synthesize histones and the enzymes that modify these proteins, which spool DNA and influence gene expression.

Early-Life Stress Exerts Long-Lasting Effects Via Epigenome
Asher Jones | Mar 18, 2021
In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
Long-Lived Trees’ Epigenetic Mutations Serve as a Molecular Clock
Jef Akst | Mar 1, 2021
Cells found in different branches of a tree have different patterns of DNA methylation, changes in which accumulate over time.
Genetic Reprogramming Restores Vision in Mice: Study
Max Kozlov | Dec 6, 2020
