A new class of anticancer drugs inhibiting the activated EGFR kinase have shown to be effective against such cancers, especially lung cancer. In a new study in PLoS Medicine, researchers have catalogued and characterized the mutations in the EGFR gene that occur in glioblastoma, a deadly type of brain tumor.
The researchers sequenced the whole coding sequence of the EGFR gene in more than 100 glioblastomas. Nearly 15% of the tumors contained missense mutations—changes that altered the amino acid sequence of EGFR. But the mutations were mostly different from the ones commonly seen in other cancers: rather than changing the kinase domain, most of the gliobastoma-associated mutations mapped to the extracellular domain of the protein.
These findings identify missense mutations in the extracellular domain of EGFR as a new way to oncogenically activate this protein. Fortunately, the drugs developed to inhibit EGFR have broad activity, which bodes well for the use of these drugs in patients with glioblastoma.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
