Expression of tight junction proteins occludin ZO-1 in jejunum and colon

Protein-to-Cytokeratin Ratio	TX/CON	RX/CON	RX/ABX	RX/GLN
Jejunumoccludin	0.040±0.004	0.079±0.028	0.108±0.038	0.105±0.55
JejunumZO-1	0.155±0.010	0.175±0.013	0.172±0.011	0.166±0.009
Colonoccludin	0.384±0.152	0.689±0.105	0.420±0.179	0.344±0.121

Data as means ± SE (N =6–8/group); zonula occludens-1 (ZO-1) and occludin are corrected for expression of cytokeratin as a loading control. All comparisons are not significant between groups.
