Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that's dependent on the sequence of the DNA and epigenetic factors. This could have implications ...

Our genes are encoded in the DNA sequence of the genome, which is highly similar across the diverse cell types of our body. Yet, each cell can only access those genes that are in an epigenetically permissive state. The epigenome ...

It was long thought that methylation, a crucial part of normal organism development, was a static modification of DNA that could not be altered by environmental conditions. New findings by researchers at the Salk Institute ...

A team of researchers from a number of institutions in the U.S. has identified a DNA methylation regulator called QSER1. In their paper published in the journal Science, the group describes studying the valleys of unmethylated ...
One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes. A team of investigators ...
