Relative mRNA expression of jejunal mucosa occludin, zonula occludens protein-1 (ZO-1), and claudin-1.

<p>Ala, diet supplemented with 12.1 g alanine/kg, Glu, diet supplemented with 20 g glutamate/kg. mRNA expression levels were normalised using β-actin as an internal control. Values are expressed as mean ± SEM. ^{a, b}Mean values within different letters were significantly different (P<0.05).
