Fig. 5. (A) Occludin mRNA distribution in the Xenopus gastrointestinal (GI) tract by quantitative real-time PCR (qRT-PCR) analysis. Occludin mRNA expression increased along the longitudinal axis of the GI tract (i.e. stomach < anterior and posterior intestine < rectum). (B–D) The effects of BW acclimation on occludin mRNA expression in Xenopus (B) anterior intestine, (C) posterior intestine and (D) rectum. Occludin mRNA expression was normalized to β-actin mRNA expression (a.u., arbitrary units). Data are expressed as means ± s.e.m., N=6–7 per group. *Significant difference (P≤0.05) from FW group. {dagger}Significant difference (P≤0.05) from 2{per thousand} BW-acclimated group.
