Researchers at TUAS Wildau Find Candidate Gene Culprits for Chronic Pain

07.05.2010
New insights by TH Wildau researchers and collaborators are reporting that chronic pain may be caused by the inadvertent reprogramming of more than 2,000 genes in the peripheral nervous system. The researchers speculate this research might ultimately lead to a therapy employing drugs that kill pain by correcting the activity of specific genes. The research was focused on the peripheral nervous system in rodent models.

According to DGSS, a section of the International Association for the Study of Pain, chronic pain affects 17% of all Germans and costs 25 billion Euro's per year in heath care alone. The quality of life of patients suffering from chronic pain can be severely limited. The pain can appear without an apparent cause and available treatments often fail to relieve it efficiently.

At the department of bioinformatics and competence center "Life Science Computing" at TH Wildau under the lead of Prof. Dr. Peter Beyerlein, powerful algorithms were developed to sort through 10.48 billion RNA sequences, assembling the complicated genomic puzzle. Researchers at Mayo Clinic carried out the wet lab experiments generating the needed mRNA molecules, which where then sequenced with Illumina's high-throughput sequencing technology, before they were transferred to Wildau. The Wildau computing results revealed a number of surprises, among them more than 10.465 novel exons and 421 novel genes.

"We were able to look much deeper into the universe of cellular processes, than ever before. It is fascinating how precisely a rigid mathematical reasoning, as consistently taught to our students, can help unveil the internal life of cells ," says Peter Beyerlein, who teaches computer science and bioinformatics in the Biosystems Engineering / Bioinformatics study course at TH Wildau.

The transatlantic team lead by the two Germans, Andreas Beutler, M.D (Mayo clinics Rochester) and Peter Beyerlein (TH Wildau) consisted of: Ronny Amberg, Paul Hammer and Gabriele Petznick all of TH Wildau, Germany;. and Michaela Banck, M.D., of Mayo Clinic; Cheng Wang, M.D., Mount Sinai School of Medicine; and Shujun Luo, Ph.D., Irina Khrebtukova, Ph.D., and Gary P. Schroth, Ph.D. all of Illumina Inc., Hayward, Calif.

The study was supported by the Richard M. Schulze Family Foundation and the National Institute of Neurological Disorders and Stroke as well as the Ministry of Science, Research and Culture (MWFK, State Brandenburg, Germany) and Philips Research, Netherlands.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
