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 ...
The research, published May 27 in Nature, reveals conserved signatures of aging and health decline and introduces new ...
A newly discovered genetic clock acts as the master timekeeper for development, orchestrating crucial bursts of gene activity ...
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 ...
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 ...
Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when ...

Mice engineered to overproduce Grik4 became visibly anxious and socially withdrawn; restoring the gene’s expression flipped both deficits back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 ...
While scientists have known for more than two decades that all cells use a strategy called RNA interference to regulate gene ...
Your genes code for all your traits. Some genes are dominant and expressed if you receive a copy from one parent. Others are recessive and only apparent if you receive a copy from both parents. Genes ...
