Couch-Potato Drugs Are WADA's First Banned for Gene-Doping Ties
[SIZE=-1]Bloomberg [/SIZE]
[SIZE=-1]Two drugs that activate genetic switches, fooling the body into believing it has exercised, are the first to be added to the Olympic sports prohibited list for their ties to gene doping. [/SIZE]
[SIZE=-1]The drugs, whose effects were first disclosed in a report published online by the journal Cell on July 31, were added to the nine-page list issued by the World Anti-Doping Agency under the Gene Doping classification as of Jan. 1. [/SIZE][...]
[SIZE=-1]One of the drugs is a synthetic protein called Aicar that, when given to mice, improved endurance by 44 percent after four weeks, even without exercise. The other is an experimental medicine made by GlaxoSmithKline Plc, GW1516, which remodeled the mices skeletal muscle and raised their endurance levels by 75 percent when the animals also ran on a treadmill. [/SIZE]
[SIZE=-1]WADAs 2009 prohibited list includes nearly 70 anabolic steroids; about 60 stimulants; hormones; diuretics and other masking agents; blood-doping methods; and several narcotics. The Montreal-based agency oversees anti-drug programs for Olympic- level sports. [/SIZE][SIZE=-1][...][/SIZE]
[SIZE=-1]Last July, a news release, titled Exercise in a Pill, announced the results of the study by the Salk Institute for Biological Studies in San Diego that detailed the effects of Aicar, which it called the ultimate couch-potato experiment, as well as the effects of GW1516. [/SIZE]
[SIZE=-1]The findings may lead to the development of obesity and muscle-wasting-disease treatments, and has implications for the treatment of diabetes and lipid disorders. [/SIZE]
[SIZE=-1]By activating different genetic switches with the two drugs, the scientists were able to increase fat burning and the mice showed major transformation of skeletal muscle fibers. In giving the mice GW1516 and a regular exercise regimen, for example, they saw a 38 percent increase in slow twitch muscle fibers, which relate to a muscles endurance. [/SIZE][...]
[SIZE=-1]Ronald Evans, who is a professor in the Salk Institutes Gene Expression Laboratory and led the research into the use of Aicar and GW1516 to manipulate signaling pathways, also developed a test to readily detect the drugs in blood and urine, and is working with WADA to enact its implementation. [/SIZE]
[SIZE=-1]While these drugs can be easily detected, other gene- therapy methods are much more problematic for WADA, and in turn sports associations and leagues. These involve the use of genetic techniques to bring doping substances to muscle tissue and other targets without passing through blood and urine, thereby confounding testing efforts. [/SIZE]
