Scientists led by Mike Hannon at the University of Birmingham and Miquel Coll at the Spanish Research Council in Barcelona have discovered a new way that drugs can attach themselves to DNA, which is a crucial step forward for researchers who are developing drugs to combat cancer and other diseases.
DNA contains the information which encodes life itself; its double-helical structure was recognised 50 years ago. Scientists soon started designing drugs to target DNA and used them to treat diseases such as cancer, viral infections and sleeping sickness. In the 1960s, scientists discovered three different classes of clinical drug, each of which recognised DNA in a different way. Subsequent drugs have used only these three ways to recognise the DNA. Now the Birmingham and Barcelona teams have found a fourth which is completely different and opens up entirely new possibilities for drug design.
The scientists have developed a synthetic drug agent that targets and binds to the centre of a 3-way junction in the DNA. These 3-way junction structures are formed where three double-helical regions join together. They are particularly exciting as they have been found to be present in diseases, such as some Huntington’s disease and myotonic dystrophy, in viruses and whenever DNA replicates itself, for example, during cancer growth.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
The oceans are the largest global heat reservoir. As a result of man-made global warming, the temperature in the global climate system increases; around 90% of...
Scientists at Helmholtz Zentrum München have discovered a mechanism that amplifies the autoimmune reaction in an early stage of pancreatic islet autoimmunity prior to the progression to clinical type 1 diabetes. If the researchers blocked the corresponding molecules, the immune system was significantly less active. The study was conducted under the auspices of the German Center for Diabetes Research (DZD) and was published in the journal ‘Science Translational Medicine’.
Type 1 diabetes is the most common metabolic disease in childhood and adolescence. In this disease, the body's own immune system attacks and destroys the...
