Epithelial barrier function of the small and large intestine of occludin ⁺/⁺ and −/− mice

	Small intestine		Large intestine
	Re	Rsub (Ω · cm2)	Re	Rsub (Ω · cm2)
Wild-type	22  ± 6 (6)	33  ± 6 (6)	70  ± 5 (7)	18  ± 2 (7)
Occludin +/−	23  ± 3 (8)NS	44  ± 4 (8)NS	70  ± 7 (8)NS	14  ± 1 (8)NS
Occludin −/−	18  ± 2 (10)NS	34  ± 3 (10)NS	65  ± 5 (10)NS	21  ± 4 (10)NS

NS, no significant difference versus control. 

R^e and R^sub were measured by alternating current impedance analysis from 16-wk-old mice. Results are means ± SEM (n, number of mice analyzed).
