Researchers at Brown Medical School and Rhode Island Hospital have shed new light on the activation of a protein key to the development of cancers, particularly breast and prostate cancer, the most commonly diagnosed cancers in the United States.
The team of cell biologists has discovered a new chemical modification that activates STAT3. This so-called signaling protein is important for embryonic growth and development, helping cells grow, duplicate and migrate. In adulthood, STAT3 presumably falls dormant, but its unexpected and continuous activation causes breast and prostate cells to develop and move through the body.
Eugene Chin, M.D., a Rhode Island Hospital researcher and assistant professor (research) of surgery at Brown Medical School, said experts suspect that environmental factors, such as a diet rich in animal fat and hormones, may activate STAT3.

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...
