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 ...

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 ...

“This is the first detailed study of how and where ORC regulates epigenetics and gene expression in human cells,” said Anindya Dutta, Ph.D., leader of the study and chair of the University of Alabama ...

Epigenetics, the study of changes in gene function that do not involve alterations to the DNA sequence, plays a pivotal role in understanding the complex interplay between genetics and the environment ...

Diet can leave lasting epigenetic marks that reshape gene expression, metabolic pathways, and disease susceptibility across the lifespan. These diet-driven molecular changes may create a form of ...

The expression of genes has to be carefully regulated in cells; active genes give cells their identity and ability to function. Epigenetic features are just one way that cells control gene expression, ...

A new drug, FLAV-27, targets epigenetic changes in Alzheimer’s. In preclinical studies, the drug reduced levels of ...

Adverse childhood experiences and traumatic events experienced or witnessed at any point during one's lifetime can sometimes ...

Changes in histone modifications of genes involved in flowering. (a) The removal of Polycomb complexes by SDG7 protein. (b) Transcription elongation and the deposition of H3K36me3 by SDG8 protein. PRE ...

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 ...
