E-mails seized in the investigation of Thomas Springstein contain references to Repoxygen, a substance used in gene therapy. Gene doping, banned in sports, involves the transfer of genes directly ...

Repoxygen, a new drug still in clinical trials, increases levels of erythropoietin (EPO), a hormone that supplies high amounts of oxygen to the muscles and increases endurance.

Repoxygen is designed for gene therapy on patients with anemia. It can boost an athlete's performance by inducing the release of erythropoietin, or EPO, a substance that stimulates the production ...

First came the Schwarzenegger mice. Then a German track coach tried to get his hands on Repoxygen. And thus began discussion about gene doping in sport. Lee Sweeney, a scientist at the University ...

Mr Parisotto believes some athletes may already be using genetically-based doping drugs, such as repoxygen, designed to switch on the body's EPO gene in response to low oxygen levels.

Werner Franke, a German scientist who has documented doping cases in the former East Germany, said Springstein’s e-mail exchanges about Repoxygen and other substances suggest criminal activity.

“Repoxygen is hard to get,” he wrote to a Dutch doctor in an e-mail revealed at a criminal trial in 2006. “Please give me new instructions soon so that I can order the product before ...

Repoxygen switches on a gene in the body when low oxygen levels are detected, increasing red blood cells and boosting oxygen levels, before turning off again.

Springstein, a one-time coach of the German Athletics Association (DLV), is thought to have used Repoxygen, a banned substance normally used in gene therapy to treat patients with anaemia.
