Gene doping is the hypothetical non-therapeutic use of gene therapy by athletes in order to improve their performance in those sporting events which prohibit.

Systematic and periodic testing of athletes — in order to detect the antibodies against viral vectors — would be required to monitor the level of anti-viral antibodies, which could potentially be used as a method for the detection of gene doping. Most transgenic proteins, especially those that enhance muscle strength, are produced locally in the injected dopajw and may be undetectable in blood or urine.
Some new substances e. It is also possible to produce genetically engineered viral vectors which are less immunogenic, thereby minimizing a host immune response [ 567 ]. Detection of DNA— recombinant human epoetin—alfa as a pharmacological ergogenic aid. Int J Sports Med. Please provide more details about your request. It is recognized that GW improves the exercise capacity of trained animals [ 51 ].
As the field of gene therapy has developed, the risk of gene doping becoming a reality has increased with it. Mini Rev Med Chem. Erythropoietin was the first recombinant haematopoietic growth factor produced and available commercially as a recombinant protein drug [ 30 ]. Polyethylenimines for in vivo gene delivery. Excessive growth of bones and tissue mass, muscle hypertrophy and hyperplasia, and stimulation by muscle regeneration IGF1.
Lack of tests to detect gene doping is associated with the fact that the protein produced by the foreign gene or genetically manipulated cells will be structurally and functionally very similar to the endogenous proteins.
Several types of rEPO are now commercially available, including: Insulin-like growth factor 1 is a protein involved in the mediation of the growth hormone. One of genetuco main functions of GH — mediated also by IGF1 — is the stimulation of body growth and body weight. An additional problem is still not completed work on the standardization of reliable tests to detect gene doping.
GENE DOPING IN SPORT – PERSPECTIVES AND RISKS
The most important biological properties of the viral vectors used in gene therapy, including the treatment of sports injuries, are shown in Table 1. GH also affects carbohydrate metabolism stimulation of glycogenolysis and increased glucose release from the liverfat metabolism increased lipolysis and decreased lipogenesis and protein metabolism increased protein synthesis [ 38 ].
The World Anti—Doping Code: This page was last edited on 27 Juneat do;aje Genetic material can be introduced into a cell either in vivo or ex vivo. Regulation of muscle fiber type and running endurance by PPARdelta. Intramuscular vascular endothelial growth factor gene therapy in patients with chronic critical leg ischemia.
The family of PPARs consists of the following genes: Annals of the New York Academy of Geneico. This effect reduces the effectiveness of the transfection efficiency by reducing the efficiency of the subsequent transgene delivery. Adjusting blood pressure by acting on angiotensin II increase in blood pressureand participation in the inactivation of bradykinin decrease in blood pressureincreasing the proportion of slow-twitch muscle fibres type I.
¿Es inaceptable el “dopaje genético”? by Andy Miah – Project Syndicate
Petersenn S, Schulte HM. It was further found that the increase in PPARD expression suppresses atherogenic inflammation [ 47 ].
Retrieved 15 December The history of concern about the potential for gene doping follows the history of gene therapythe medical use of genes dooaje treat diseases, which was first clinically tested in the s.
Specific reference ranges should be established with regard to gender, population and sport. Get our weekly newsletter.

Viral vectors Biological properties of vector Adenoviruses efficiency: So far, there are no published literature data confirming the occurrence of side effects associated with transfer of the PCK1 gene or protein used as doping. Non-viral gene delivery techniques are less effective methods of introducing genetic material into human cells, though characterized by low cytotoxicity. Structure and function of the growth—hormone— releasing hormone receptor. Another strategy is proteomic profiling.
However, despite the documented and unpredictable risks associated with gene doping, some athletes ignore safety issues. Abstract In the past few years considerable progress regarding the knowledge of the human genome map has been achieved. Gene doping and sport” PDF.
