Protein plays role in inherited cancer syndrome, may be key to other tumors
A research team based at Massachusetts General Hospital (MGH) has identified a key cellular function of a protein known to be involved in the rare genetic disorder neurofibromatosis type 2 (NF2). The protein, called merlin, plays a key role in cell-to-cell communication and may be involved in other types of cancer. The discovery also may support the theory that some tumors are destined to spread or metastasize from the outset, rather than gaining the ability to spread as they develop. The report appears in the May 1, 2003, issue of Genes & Development.
NF2 is a rare inherited disorder characterized by multiple tumors of the spine and brain. The NF2 gene was discovered in 1993 by researchers from MGH and elsewhere. At the time of its discovery it was apparent that the NF2 gene was a tumor suppressor, but its exact function was unclear. The protein encoded by the NF2 gene, given the name merlin, was found at the interface of the cell membrane with the cytoskeleton, a network of filaments that supports the cell.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
