Aquaporin-8 expression is reduced in ileum and induced in colon of patients with ulcerative colitis

Figure 1 AQP8 mRNA expression in biopsies of controls and UC patients. Real-time RT-PCR analysis was performed in ileal and colonic biopsy samples from control individuals and UC patients. TaqMan real-time RT-PCR results are expressed as relative gene expression referring to GAPDH expression as a housekeeping gene. The results from 8 individuals are combined. The extremal values, the mean value and the standard deviation are shown for each group.
