Administration of recombinant human erythropoietin (rHuEpo) improves performance and hence is subject to abuse by athletes. The detection of rHuEpo doping remains a major challenge at present. The aim of the current study was to investigate whether circulating microRNA (miRNA) can be used for detecting r-HuEpo doping. Twenty trained males received rHuEpo injections of 50 IU∙kg -1 body mass every two days for 4 weeks. Blood was obtained 2 weeks before, during and 4 weeks after administration. For this pilot analysis, plasma miRNA expression was assessed at selected time points using the Affymetrix GeneChip 3.0 and the miScript 384 HC PCR Array (Qiagen). For the Affymetrix microarray data, GC…
