Supplementary Figure 1: Analysis of claudin expression in human colonic samples

Total mRNA was isolated from 24-35 human samples of human control tissue or IBD tissue. Expression of PIAS1, SOCS3, CLDN1 and CLDN2 mRNA in human colonic tissue of IBD patients was analyzed. SOCS3 and CLDN2 mRNA levels were up regulated in active UC patient samples. Significant differences are indicated.
