Researchers at the University of Toronto have mapped the molecular details that show how a viral protein coded in the Epstein-Barr virus immortalizes cells and causes them to continuously grow, thereby predisposing people to certain types of cancer.
"Epstein-Barr virus (EBV) is one of the most common human viruses in the world and is strongly linked to certain b-cell cancers like Burkitts lymphoma as well as the epithelial cell cancer, nasopharyngeal carcinoma. EBNA1 is a protein coded in the Epstein-Barr virus and suspected to play a role in the development of cancer," says Lori Frappier, professor in medical genetics and microbiology at U of T and senior author of a paper in the April 1 issue of Molecular Cell.
"This research shows how EBNA1 interferes with natural cell growth regulation by binding to a particular protein in cells, causing them to continue growing and therefore increasing the risk of becoming cancerous."

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
