Figure 1From: Exercise-induced up-regulation of MMP-1 and IL-8 genes in endurance horsesRelative expression bar chart. Bar chart of expression of IL-8 and MMP-1 in 10 endurance horses during a time course experiment (basal, race, 24 h). Error bars indicate the 95% confidence interval. Relative expression values are on a logarithmic base 2 scale. Asterisks indicate significance at P < 0.001.Back to article page
