Retroviruses are re-writing the koala genome and causing cancer

The koala retrovirus (KoRV) is a virus which, like other retroviruses such as HIV, inserts itself into the DNA of an infected cell. At some point in the past 50,000 years, KoRV has infected the egg or sperm cells of koalas, ...

New-found molecular signature keeps key genes ready for action

During development, scores of molecular signals prod cells to take on specialized identities and functions. In response to some of these signals, the cellular machinery awakens specific genes called 'immediate early genes' ...

At the core of the integrator complex

Gene expression is a highly regulated process that involves several steps. These include transcription of DNA instructions into RNA, removal of non-coding segments from the RNA message, and its subsequent translation into ...

Genes that dance to the circadian rhythm

Scientists at EPFL have made breakthrough discoveries on the circadian clock and how it affects gene expression. Some of the findings suggest a biological underpinning for different behaviors in people, such as morning people, ...

Researchers report new technique to image the cell nucleus

Nestled deep in the nucleus of each of your cells is what seems like a magic trick: Six feet of DNA is packaged into a tiny space 50 times smaller than the width of a human hair. Like a long, thin string of genetic spaghetti, ...

Understanding how genetic motifs conduct 'the music of life'

Our genetic codes control not only which proteins our cells produce, but also—to a great extent—in what quantity. This groundbreaking discovery, applicable to all biological life, was recently made by systems biologists ...
