Figure 4. Relative mRNA expression of (A) peptide transporter-1 (PEPT-1), (B) zonula occludens-1 (ZO-1), (C) occludin, and (D) claudin-2 between trained animals without supplementation (T group) and trained animals supplemented with alanyl-glutamine (T-AG). The data are reported as median, minimum and maximum, and interquartile range (n=8). *P<0.05 compared with the T group (Mann-Whitney test).
