  • Recent advancements in gene therapy pose a risk for misuse in sports doping, highlighting the need for improved testing methods.
  • Researchers aimed to create a gene doping model using a specific viral vector (rAAV9-h) in mice, which resulted in noticeable changes indicating successful genetic manipulation.
  • The study established direct and indirect detection methods for gene doping through advanced qPCR assays, laying groundwork for future testing in athletes.

Article Abstract

With the rapid development of gene therapy technology in recent years, its abuse as a method of sports doping in athletics has become a concern. However, there is still room for improvement in gene-doping testing methods, and a robust animal model needs to be developed. Therefore, the purposes of this study were to establish a model of gene doping using recombinant adeno-associated virus vector-9, including the human erythropoietin gene (rAAV9-h), and to establish a relevant testing method. First, it was attempted to establish the model using rAAV9-h on mice. The results showed a significant increase in erythrocyte volume accompanied by an increase in spleen weight, confirming the validity of the model. Next, we attempted to detect proof of gene doping by targeting DNA and RNA. Direct proof of gene doping was detected using a TaqMan-qPCR assay with certain primers/probes. In addition, some indirect proof was identified in RNAs through the combination of a TB Green qPCR assay with RNA sequencing. Taken together, these results could provide the foundation for an effective test for gene doping in human athletes in the future.

Annual Banned-Substance Review 17th Edition-Analytical Approaches in Human Sports Drug Testing 2023/2024.

Drug Test Anal

December 2024

Center for Preventive Doping Research, Institute of Biochemistry, German Sport University Cologne, Cologne, Germany.

The 17th edition of the annual banned-substance review on analytical approaches in human sports drug testing is dedicated to literature published between October 2023 and September 2024. As in previous years, focus is put particularly on new or enhanced analytical options in human doping controls as well as investigations into the metabolism and elimination of compounds of interest, which represent central (while not exclusive) cornerstones of the global anti-doping mission. New information published within the past 12 months on established doping agents as well as new potentially relevant substances are reviewed and discussed in the context of the World Anti-Doping Agency's 2024 Prohibited List.

As emerging contaminants, antibiotic-resistant bacteria (ARBs) and antibiotic-resistant genes (ARGs) pose a serious threat to human health and ecological security. Here, a reduced graphene oxide and g-CN co-doped copper ferrite (rGO-CNCF) were synthesized. The composite material was characterized using XRD, FTIR, XPS, SEM-EDS, TEM, and DRS analysis methods, and a visible-light-assisted rGO-CNCF-activated PMS system was constructed for the removal of ARB and ARGs in water.

The detection of endogenous anabolic androgenic steroids misuse in Asian population using the Steroidal Module of the Athlete Biological Passport (ABP) is a challenge due to the high prevalence of UGT2B17 gene deletion polymorphism with low levels of testosterone (T) glucuronide. In this study, the capabilities of different approaches based on urine analysis for the detection of oral T undecanoate administration were evaluated in 13 Asian volunteers, including 11 subjects with del/del genotype and 2 subjects with del/ins genotype. In the first part of the work, the effect on the urinary steroid profile (SP) and on the isotope ratio mass spectrometry markers was evaluated.
