A University of Minnesota study has confirmed the pivotal role of an enzyme known as JNK2 in the development of nonmelanoma skin cancers. The findings suggest that JNK2 should be evaluated as a target for the prevention and treatment of such cancers. Lead author Zigang Dong, director of the university’s Hormel Institute in Austin, Minn., will present the work at 8:30 a.m. Sunday, July 13, at the American Association for Cancer Research meeting in the Washington Convention Center, 801 Mount Vernon Place NW, Washington, D.C.
Ultraviolet rays from the sun are the major culprit in skin cancer, which accounts for more than half the cancers in the United States. The process of cancer development involves a chain of interactions among biochemicals in the skin, and biochemicals that play key roles in carcinogenesis make potential therapeutic targets. Many human cancers show elevated activity in some form of JNK enzyme, and the enzyme is also activated by sunlight, Dong said.
"Even if one goes into the sun for a few minutes, the activity of JNK in the epidermis rises," said Dong. "If you go out for a few minutes, JNK activity doesn’t stay elevated. But it looks as though if a person gets too much sun exposure, JNK activity becomes permanently elevated and cancers develop. This study indicates that some form of JNK activity is a key step in the process by which nonmelanoma cancers grow."

An international research team including astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has combined radio telescopes from five continents to prove the existence of a narrow stream of material, a so-called jet, emerging from the only gravitational wave event involving two neutron stars observed so far. With its high sensitivity and excellent performance, the 100-m radio telescope in Effelsberg played an important role in the observations.
In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors....
Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.
The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...
For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.
The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
