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
Hilden, Germany / Everest Base Camp, Nepal - May 26, 2008 - In the
run-up to the Summer Olympics, scientists are taking an innovative
approach to develop new molecular testing methods for performance
manipulation on the genetic level. A team of researchers from the
University of Pennsylvania today is attempting to climb Mount
Everest, taking with them for the first time live mice to the "roof
of the world". The effort is being supported by the World Anti-Doping
Agency (WADA) and the molecular diagnostics company QIAGEN. The
purpose of the researcher's historic climb is to investigate tissue
and blood samples from the mice to create a molecular signature for
altitude-induced hypoxia. The scientists' ultimate goal is the
development of novel testing methods for gene doping by comparing
such natural molecular signatures with induced signatures that would
be created by gene doping. Such practices have been listed on WADA's
index of banned substances since 2003, but the identification of
athletes using gene doping is still not possible. Accordingly,
experts consider gene doping to be one of the most urgent problems in
sports today.
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."
According to Peer Schatz, Chief Executive Officer of QIAGEN, this
expedition shows how molecular biology is increasingly helping to
find solutions for critical issues in many areas of our daily lives:
"We are very pleased to partner with the team from the University of
Pennsylvania in this exciting project, in which our sample and assay
technologies will be used for the development of testing methods in
the harshest of conditions. We are also proud to be contributing to
the team's so important goal of making anti-doping controls more
effective."
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.
Background Gene Doping
Gene doping as defined by the WADA encompasses the non-therapeutic
use of cells, genes, genetic elements, or of the modulation of gene
expression, having the capacity to enhance athletic performance. An
example for such doping approaches is a method to increase the
organism's own production of EPO using an active agent called
HIF-stabilizers. Usually, a protein called hypoxia-induced factor
(HIF) ensures the sufficient supply of oxygen to cells as it
stimulates the production of EPO in low oxygen environments. When the
oxygen concentration rises, both the production of HIF and of EPO
decreases. This process is driven by an enzyme called HIF-PH, which
reduces HIF. So called HIF-stabilizers can be used to stop the enzyme
from functioning, resulting in a slower reduction of HIF and thus
higher EPO levels. New products for the treatment of anemia currently
under development tackle exactly this mechanism using
HIF-stabilizers.

Background QIAGEN
QIAGEN N.V., a Netherlands holding company, is the
leading global provider of sample and assay technologies. Sample
technologies are used to isolate and process DNA, RNA and proteins
from biological samples such as blood or tissue. Assay technologies
are used to make such isolated biomolecules visible. QIAGEN has
developed and markets more than 500 consumable products as well as
automated solutions for such consumables. The company provides its
products to molecular diagnostics laboratories, academic researchers,
pharmaceutical and biotechnology companies, and applied
testing customers for purposes such as forensics, animal or food
testing and pharmaceutical process control. QIAGEN's assay
technologies include one of the broadest panels of molecular
diagnostic tests available worldwide. This panel includes the only
FDA-approved test for human papillomavirus (HPV), the primary cause
of cervical cancer. QIAGEN employs more than 2,700 people in over 30
locations worldwide. Further information about QIAGEN can be found at
