Blood SLC41A1 gene expression prior and subsequent to exercise and 24 h after exercise. The SLC41A1 mRNA expression levels were quantified by qPCR analysis and normalized to the reference gene, β-actin, expression. Data are presented as means + SEM (n=8).*P<0.05 vs. the basal levels within the group (the Wilcoxon signed-ranks test). SLC41A1, solute carrier family 41 member A1; qPCR, quantitative polymerase chain reaction; SEM, standard error of the mean.
