Conventional wisdom holds that cancer cells contain so many mutations that theres no way to return them to the straight and narrow path of their normal neighbors. This has led to cancer treatments that focus on destroying or removing the cancerous cells.
But new research by Dean Felsher, MD, PhD, assistant professor of medicine (oncology) and of pathology at the Stanford University School of Medicine, suggests that cancer cells can be reformed. His work, published in the Oct. 10 advance online issue of Nature, could lead to new ways of treating the most common forms of cancer. Felsher found that turning off just one cancer-causing gene is enough to eliminate aggressive, incurable liver tumors in mice in just four weeks. These cells still had the mutations that made them cancerous in the first place, except that one. He had documented a similar phenomenon in bone cancer two years ago, but liver cancer is more common and difficult to cure. "This is a terrible cancer," said Felsher. "Anything that is encouraging in liver cancer may be important."
Liver cancer is formed in a type of cells called epithelial cells - the same ones that form cancers in the breast, colon and prostate. Felshers findings about liver cancer could also apply to these types of cancer. Felsher hopes his work pushes people to find drugs that specifically hamstring the protein in question: Myc (pronounced "mick"), which is one of the most commonly mutated oncogenes in cancer cells.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
