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

Organisms are made up of cells, and in each of those cells, a genome encodes the instructions for that organism to grow and survive. The human genome has at least 20,000 genes, and the expression of ...

Switches' in our DNA that affect gene activity in cells could be crucial to understanding and possibly treating Alzheimer's ...

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human ...

Scientists mapped hidden DNA switches in brain support cells to understand how gene control may influence Alzheimer’s disease ...

Though almost every cell in your body contains a copy of each of your genes, only a small fraction of these genes will be expressed, or turned on. These activations are controlled by specialized ...

DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...

Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene ...

Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and ...

A multi-institutional team of researchers led by Case Western Reserve University has identified a pattern of clustered genetic changes that appear to encourage growth of colorectal cancer tumors—a ...
