What is gene doping used for?
Gene doping. Gene doping is an outgrowth of gene therapy. However, instead of injecting DNA into a person’s body for the purpose of restoring some function related to a damaged or missing gene, as in gene therapy, gene doping involves inserting DNA for the purpose of enhancing athletic performance.
What are the effects of gene doping?
One of the side effects in gene therapy and doping with myostatin blockers is over expression of these genes and increased muscles over their natural size, which as a result increases overload on tendons and bones, or damages differential stresses on them.
What is meant by gene doping and blood doping?
Gene or cell doping is defined by the World Anti-Doping Agency (WADA) as “the non-therapeutic use of genes, genetic elements and/or cells that have the capacity to enhance athletic performance”.
How much does it cost for gene editing?
Currently, the cost of human genome editing therapies ranges between $373,000 and $2.1 million4.
Do athletes use gene doping?
Unfortunately, genetic methods developed for therapeutic purposes are increasingly being used in competitive sports. Some new substances (e.g., antibodies against myostatin or myostatin blockers) might be used in gene doping in athletes.
Which international agency provides guidelines on doping?
The World Anti-Doping Agency (WADA) Prohibited List is an international standard identifying substances and methods prohibited in sport.
What are substance used in doping?
Substances and methods used in doping
- ERYTHROPOIETIN (EPO) * EPO is a peptide hormone that is produced naturally by the human body.
- CERA.
- ANABOLIC STEROIDS.
- HUMAN GROWTH HORMONE.
- DIURETICS.
- SYNTHETIC OXYGEN CARRIERS.
- BLOOD DOPING.
- INSULIN.
What are the most common drugs used in doping?
Common performance-enhancing drugs
- Creatine. Creatine is a naturally occurring compound in the body that’s also sold as an over-the-counter supplement.
- Anabolic steroids.
- Steroid precursors.
- Amphetamines and other stimulants.
- Caffeine.
How do you make blood doping?
In blood doping, the athlete’s own red blood cells are re-added to the bloodstream. This can be done by withdrawing one half to one litre of blood three to five weeks before a race. The withdrawn blood will be centrifuged, after which the red blood cells are collected and stored in a refrigerator.
What is gene doping and how does it work?
The roots of gene doping lie in gene therapy, the decades-old idea of inserting genes into the body’s cells to correct genetic flaws that cause diseases such as juvenile diabetes, hemophilia, and cystic fibrosis. Although simple in concept, gene therapy has been tricky to carry out reliably in patients.
Can we detect gene doping in athletes?
The ability to detect gene doping is perhaps our best weapon for fighting against a new era of performance enhancement in the world of athletics. This opinion is certainly shared by the World Anti-Doping Agency and the many scientific research groups striving to develop ways of detecting genetic manipulation in athletes.
Are bioengineered drugs a doping drug?
For example, unlike classic doping drugs such as steroids, bioengineered substances are chemically identical to the body’s natural hormones, making detection difficult at best. Gene editing adds additional layers of concerns.
Can gene doping be used for EPO in cycling?
The abuse of rEPO is epidemic in cycling, leading to frequent controversy, tedious forensic investigations, and serious side effects, including death [9]. Using gene doping, an additional EPO gene could be delivered to the athlete by way of a viral vector.
