Verification of gene expression by real-time PCR analysis of intestinal biopsy samples.

<p>Expression levels of selected genes were measured in 40 intestinal biopsy samples from the terminal ileum (TI), ileocecal valve (ICV), appendiceal orifice (AO), and sigmoid colon (SC) and normalized to glyceraldehyde-3 dehydrogenase (GAPDH) transcript levels. Values were log transformed as shown. Horizontal bars indicate median expression levels. Statistical significance between groups was determined by two-tailed Mann Whitney test. *<i>P</i><0.05; **<i>P</i><0.01; ***<i>P</i><0.001.
