Abstract:
Background: The analysis of individual microRNAs (miRNAs) as a diagnostic and
prognostic tool for the effective treatment of various diseases has aroused particular interest in the
scientific community. The determination of circulating miRNAs makes it possible to assess biological
changes associated with nutritional processes, the intake of dietary supplements and drugs, etc.
The profile of circulating miRNAs reflects the individual adaptation of the organism to the effect of
specific environmental conditions.
Objective: The objective of this study is to systematize the data and show the importance of circulating
miRNAs as new potential biomarkers of the organism's response to the intake of various dietary
supplements, drugs, and consider the possibility of their use in doping control.
Methods: A systematic analysis of scientific publications (ncbi.nlm.nih.gov) on the miRNA expression
profile in response to the intake of dietary supplements and drugs most often used by athletes,
and supposed their role as potential markers in modern doping control was carried out.
Results: The profile of circulating miRNAs is highly dependent on the intake of a particular drug,
and, therefore, may be used as a marker of the effects of biologically active supplements and drugs
including the substances from the Prohibited List of the World Anti-Doping Agency (WADA).
Conclusion: Monitoring of circulating miRNAs can serve as a high-precision marker for detecting
doping abuse in elite sports. However, it is necessary to conduct additional studies on the effect of
complex drugs on the profile of circulating miRNAs and individual circulating miRNAs on a particular
biological process.
