Johns Hopkins scientists have identified a protein in fruit flies whose counterpart product in humans may help cause cancer.
The researchers report in the Aug. 12 issue of Cell that a protein dubbed Yorkie directly controls the fruit flys organ size and, when overabundant, causes increased cell growth and decreased cell death, hallmarks of cancer. Yorkies relative in mammals, called YAP, appears to do the same thing, the researchers report, which suggests that in humans, a defect in the gene that makes YAP might contribute to cancer.
"Over the past few decades, science has identified a few so-called oncogenes, whose protein products act as accelerators and trigger abnormal cell growth," said Duojia Pan, Ph.D., who carried out most of the study at the University of Texas Southwestern Medical Center at Dallas before coming to the Johns Hopkins Institute for Basic Biomedical Sciences. "YAP seems to be another one and our lab is already investigating the amount of YAP protein in human tumors to see if excessive amounts are there."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
