Abstract
Doping can be both of chemical and protein nature or may involve prohibited methods, such as illegal blood transfusions. The rapidly increasing number of genetic therapies as a promising new branch of regular medicine, has raised the issue whether these techniques might be abused in the field of sports. The risks involved in gene doping are several, and are related both to the vector protein used (DNA, chemical, viral) and to the encoded transgene. A concern in the athletic community is that no one knows how easily gene doping can be detected. The DNA used for gene transfer is of human origin, and not different from that of the person applying gene doping. A combination of developing detection methods based on gene arrays or proteomics and a clear education program on the associated risks seems to be the most promising preventive method to counteract the possible application of gene doping.
