New study shows aklylating DNA damage stimulates regulated necrotic cell death
Researchers at the Leonard and Madlyn Abramson Family Cancer Research Institute at the University of Pennsylvania have found a second way by which chemotherapeutic agents can kill cancer cells. The finding – which will appear online and ahead of print in the June 1st edition of the journal Genes & Development – represents an important advance in understanding how and why some cancer cells die and others do not in response to existing chemotherapy. The results suggest the possibility that targeted therapies can be developed which will force cancer cells to die before they can grow into tumors.
"This finding shows, for the first time, that cancer cells are unusually sensitive to dying by necrosis, when their ability to metabolize glucose is blocked," said Craig Thompson, MD, Principal Investigator of the study and Scientific Director of the Abramson Family Cancer Research Institute (AFCRI). "Up until now, research has focused on finding ways to program cancer cells to die through apoptosis – a very regulated, orderly form of cell death that does not trigger an immune response. Now, we know that cancer cells can be forced to die, suddenly, through necrosis. If we can harness this method, which does trigger an immune response, then, the door will be opened to a whole new and less toxic way to treat cancer."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
