The study was published this week as the cover article of the journal Science Signaling.
The focus of the study was angiomotin, a protein that coordinates cell migration, especially during the start of new blood vessel growth and proliferation of other cell types.
“We were the first to describe angiomotin’s involvement in cancer,” said Joseph Kissil, a TSRI associate professor who led the studies. “ And while some following studies found it to be inhibiting, we wanted to clarify its role by using both cell studies and animal models. As a result, we have now found that it is not an inhibitor at all, but instead is required for Yap to produce new tumor growth.”
Yap (Yes-associated-Protein) is a potent oncogene that is over-expressed in several types of tumors.
In addition to identifying angiomotin’s critical role in tumor formation, Kissil and his colleagues found the protein is active within the cell nucleus. Earlier cell studies focused on the function of the protein at the cell membrane.
“This pathway, which was discovered less than a decade ago, appears to regulate processes that are closely linked to cancer,” Kissil said. “The more we study it, the more we see its involvement.”
The first authors of the study, “The p130 Isoform of Angiomotin Is Required for Yap-Mediated Hepatic Epithelial Cell Proliferation and Tumorigenesis,” are Chunling Yi of Georgetown University Medical Center and Zhewei Shen of the University of Pennsylvania. Other authors include Anat Stemmer-Rachamimov of Massachusetts General Hospital; Noor Dawany, Louise C. Showe and Qin Liu of The Wistar Institute; Scott Troutman of TSRI; Akihiko Shimono of TransGenic, Inc.; Marius Sudol of Geisinger Clinic; Lars Holmgren of Karolinska Institutet, Stockholm; and Ben Z. Stanger of the University of Pennsylvania.

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...
