Study finds AKT blocks cancer cell motility; paradoxical discovery raises questions in developing cancer inhibitor therapies
In investigating the molecular mechanisms of cancer cell motility – the unique property that enables cancer to spread from its primary origin to other parts of the body – researchers have uncovered a surprising role for the AKT/PKB (protein kinase B) enzyme, providing important new insights into cancer metastasis and suggesting that current efforts to develop cancer therapies by inhibiting AKT may be inadvertently promoting the spread of the disease.
Led by a scientific team at Beth Israel Deaconess Medical Center (BIDMC) and described in a study in the Nov. 23 issue of the medical journal Molecular Cell, the research demonstrates for the first time that AKT, which is known to increase cancer cells survival capability also paradoxically increases their motility and invasion abilities, thereby preventing cancer from spreading.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
