Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Researchers identify a gene expression program in the living human brain that tracks with real-time neurotransmission, ...

Livestock breeders could soon have more tools to improve the health and quality of their animals, thanks to a recent study ...

Our brain is arguably the organ that most distinguishes humans from other primates. Its exceptional size, complexity and capabilities far exceed those of any other species on Earth. Yet humans share ...

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 ...

GLP-1s are building a reputation as "wonder drugs." First characterized for their ability to improve insulin release and treat diabetes, the drugs were later found to promote weight loss and improve ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

Scientists usually study the molecular machinery that controls gene expression from the perspective of a linear, ...

What if you could flip a genetic switch to silence a gene, then turn it back on with a simple drug? For researchers, gene-switch tools offer that kind of control—and a new system called Cyclone may ...

This article explains how diet creates sustained epigenetic changes that affect long-term health, disease risk, aging, and ...
