Effects of dietary supplementation with sulfur amino acids (SAA) on mRNA expression of tight junction of F1 to F3 cell fraction in weaning piglets. The mRNA expression abundances of Claudin-1, Occludin, and ZO-1 were normalized using β-actin as an internal control. P values of <0.05 were used to indicate statistical significance. Data are expressed as means ± SEM; n = 5. T = effects of dietary treatment; S = effects of crypt villus axis section; T × S = effect of interaction between dietary treatment and crypt villus axis section.
