Researchers are investigating the role of non-coding DNA, or junk DNA, in regulating astrocytes, brain cells involved in ...

Non-coding DNA variants contribute to acute lymphoblastic leukemia (ALL) chemotherapy resistance. St. Jude Children's Research Hospital scientists have identified specific DNA variants in the ...

The non-coding genome, once dismissed as "junk DNA", is now recognized as a fundamental regulator of gene expression and a key player in understanding complex diseases. Following the landmark ...

Why cells grow to just the right size has long baffled scientists. Too small or too large, and cells can trigger serious diseases, but the genetic switch behind this balance has remained elusive. Now, ...

Noncoding elements in the genome, such as enhancers, silencers, and insulators, play important roles in gene expression and thus cellular behavior. Therefore, these elements may be of particular ...

The puzzle seems impossible: take a three-billion-letter code and predict what happens if you swap a single letter. The code we’re talking about—the human genome—stores most of its instructions in ...

Only around two percent of the human genome codes for proteins, and while those proteins carry out many important functions of the cell, the rest of the genome cannot be ignored. However, for decades ...

The human genome contains about 20,000 protein-coding genes, but that only accounts for roughly two percent of the genome. For many years, it was easier for scientists to simply ignore all of that ...

Scientists have been alert to genetic drivers of cancer that are embedded in the transcriptome, which consists of DNA’s coding regions. Beyond the transcriptome, in the wider genome, lurk additional ...

Retinitis pigmentosa (RP) is a genetic eye disorder affecting around one in 5,000 people worldwide. It typically begins with ...

Much of the "junk" DNA in Drosophila shows signs of either negative or positive selection, according to a study in this week's Nature. An analysis by Peter Andolfatto of the University of California, ...
