Epigenetics, the dynamic regulation of genetic expression, involves complex molecular mechanisms. While the process of gene silencing by methylating the H3K27 position in histones is understood, not ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

Epigenetics is a rapidly growing field of study that focuses on the heritable changes in gene expression that occur without alterations to the underlying DNA sequence. These changes are caused by ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

A research team has recently made a significant breakthrough in understanding how the DNA copying machine helps pass on epigenetic information to maintain gene traits at each cell division.

Northwestern Medicine scientists have discovered how molecular "traffic controllers" in cells influence aging and cellular ...

The genome is a fascinating place, consisting of complex loops of DNA that are transcribed into RNA, which is translated into protein. However, DNA expression is controlled by factors beyond the ...

Salk Institute researchers find new mode of epigenetic targeting, showing for the first time that genetic sequences can direct new DNA methylation patterns in plants LA JOLLA (November 21, 2025)—All ...
