Computer key unlocks heritable disorders

08.03.2007
Danish and Belgian researchers have found a computer key that maps genes underlying heritable disorders, such as breast cancer, multiple sclerosis, and Alzheimer’s disease. These results will possibly ease the discovery of new medicines and improve treatment in various disorders.

The results – which are published in the current issue of Nature Biotechnology – show that genes important for the development of diseases like Alzheimer’s follow the same cellular rules as genes involved in fundamentally different disorders, such as heart disorders, multiple sclerosis, breast cancer, and Type 2 diabetes.

”Many disorders manifest themselves in fundamentally different ways, but the new surprising discovery is that the underlying genes play together after the same rules. Our results show that the genes that trigger diseases, regardless of the type of disease in question, are social team players who cooperate according to highly specific rules. These rules have now been mapped, and we have pointed at hundreds of new genes that are likely to be involved in disorders including multiple sclerosis, Parkinson, heart disorders, and diabetes”, says Kasper Lage from Technical University of Denmark, who is the project coordinator on this work.

Heritable disorders will be easier to interpret for clinicians using the new results. Furthermore, the identification of new genes likely to be involved in disorders will help patients with defects in these genes. For example, if you are a high risk carrier of a gene that underlies a disease such as Type 2 diabetes, physicians could prevent or delay the manifestations of the disease by dietary guidance early in life.

”This is a crucial breakthrough for our understanding of heritable disorders, and a breakthrough for systems biology as a research strategy in the field genetics and disease”, says Søren Brunak leader of Center for Biological Sequence analysis at the Technical University of Denmark. ”We work with genes and proteins, but also with clinical literature describing the characteristics of different disorders. Then we let the computer integrate all of these data, and extract the pattern”, he adds.

The results are the product of a collaboration between the Center for Biological Sequence analysis, the Wilhelm Johannsen Center for Functional Genomics, Steno Diabetes Center in Denmark, and the SymBioSys Center for Computational Systems Biology, Katholieke Universiteit Leuven in Belgium.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
