Sports Doping Researchers to Tackle Mount Everest
In the run-up to the Olympics scientists use live mice for the first time on the "roof of the world" to develop new tests for gene doping
The scientific team headed by Prof. Dr. Tejvir S. Khurana and Dr. Gabriel Willmann is specifically looking to find those genes that are active in a low-oxygen environment and thus enable the organism to adapt to the altered environmental conditions. In general, hypoxia has a positive influence on the body's performance as it stimulates the creation of erythropoietin (EPO), a naturally occurring hormone that promotes the production of red blood cells. When applied artificially, EPO can be easily discovered. However, if gene activity is manipulated in a way that the body produces more "natural" EPO and therefore more red blood cells without being exposed to a low oxygen environment, existing doping-detection methods prove ineffective - at least so far. Now, the University of Pennsylvania scientists intend to solve this problem by developing markers for a test that can discriminate between naturally induced activations and activations induced through gene doping.
"We are very excited that the attack on the summit is now beginning. From a research point of view, a major challenge of this endeavor will be the extraction of samples from the mice under these extreme conditions," said Dr. Gabriel Willmann, one of the initiators of the research project. "The cooperation with QIAGEN, as the world's leading provider of sample and molecular testing technologies, will help us enormously to successfully collect, process and analyze the samples. Therefore, we are confident that first results will be ready for presentation shortly after our return."
In addition to new testing methods for the identification of doping offenders, the scientists also hope to generate new data that may lead to a better treatment of muscular dystrophy. The incidence of this genetic disease is comparatively low, yet it is also incurable and leads to a significant loss of expectation of life. As the disease also affects respiratory muscles, patients in an advanced stadium experience a level of hypoxia comparable to the effects of exposure to extreme altitudes.
