UF, French scientists seek test to detect gene doping in athletes
... It sounds futuristic, but experts say its only a matter
of time. Unscrupulous athletes began showing an interest in gene doping in 2004, when the first reports of muscle-boosting therapies in mice were published by University of Pennsylvania researchers. Since then, several potential targets of gene do...
