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 ...

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 ...

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 ...

For decades, biologists treated DNA as a static string of letters, a linear code that cells read like text on a page. A new ...

Neurodegenerative diseases, such as Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are medical conditions characterized by the progressive degradation ...

With a new study in the journal Cell, researchers at Stanford University and Stockholm University have contributed to ...

The microbes in our gut have a significant impact on many aspects of our health. New research has indicated that bacteria in the gastrointestinal tract can affect the activation of gut genes. Gene ...

An important player in the healthy development of female embryos turns out also to play a key role in regulating the behavior of chromosome loops and gene expression in both sexes, according to a new ...

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the nucleosome regulates the positioning of INO80. This highlights that the ...

Monitoring gene activity in the brain just got a major upgrade. Rice University bioengineers have developed a novel serum ...
