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 ...
Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when ...
DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...
Scientists cannot reliably predict whether an individual carrying certain gene variants will eventually end up obese. Put ...
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 ...

Mice engineered to overproduce Grik4 became visibly anxious and socially withdrawn; restoring the gene’s expression flipped both deficits back
Researchers have shown that mice carrying extra copies of the Grik4 gene developed clear signs of anxiety and social ...
People who vape regularly show altered activity in 3,124 genes across the genome compared with people who do not smoke or vape. While some of those changes (28.8%) relate to how often or how much ...
