Blood manipulations (e.g. blood transfusion, recombinant human erythropoietin (rHuEPO) injections) are currently being used by athletes to enhance their sporting performance despite these methods being prohibited by the World Anti-doping Agency (WADA). Recent advances in “omics” technologies have provided new high-throughput techniques that may facilitate the discovery of new biomarkers for anti-doping purposes [1, 2].

This study aimed to test the application of whole transcriptome analysis to the detection of autologous blood transfusion (ABT).

15 healthy Caucasian male (20-35 yrs old, BMI ≤ 30 kg/m2) donated 500 mL of blood that was stored and then infused 36 days later. Whole blood samples were collected 4 days and 1 day before blood transfusion and at 3, 6 and 12 hours, 1,2,3,6,9 and 15 days after blood transfusion. Total RNA was extracted and 100 ng/ul of total RNA used for gene expression analysis using the GeneChip HTA 2.0 from Affymetrix UK Ltd ( > 285,000 full-length transcripts). One-way repeated measure analysis of variance (ANOVA) was used to identify differential expressed genes following ABT. Changes considered significant at ANOVA p-value < 0.05 and a fold change (FC) of 1.5.

As the study is ongoing, we present the results of 8 subjects and only 5 time points (baseline one day before, 3, 6, 9 and 15 days after ABT). Compared to baseline, 202 genes were differentially expressed 3 days after ABT, 170 genes after 6 days, 218 genes after 9 days and 51 genes after 15 days. Approximately 91 genes were differentially expressed among time points, with 23 genes overlapping and upregulated 3, 6 and 9 days after ABT; fold changes varied from 1.5 to 2.9. Of these differentially expressed genes, three overlapped with 45 previously identified rHuEPO genes. Specifically, ALAS2 was downregulated 6 days (FC = −1.77, ANOVA p = 0.003), 9 days (FC = −1.84, ANOVA p = 0.007) and 15 days after ABT (FC = −1.5, ANOVA p = 0.011). CCR7 was upregulated (FC = 1.83, ANOVA p = 0.049) 3 days after ABT and SLC4A1 was downregulated (FC = −1.65, ANOVA p = 0.023) 6 days after ABT. Although preliminary, these results are encouraging and support the detection of autologous blood transfusion using whole genome expression.
