Gene-expression profiles in multiple gastrointestinal disorders. Expression levels of 44 target genes were determined by quantitative RT-PCR and normalized to expression of GAPDH. Expression levels of 25 genes are shown; expression levels of the remainder were not statistically different between CTRL and any disease cohort. Results are expressed as transcript levels of individual genes relative to transcript levels of GAPDH using the formula: 2(GAPDH C
-target gene C
). Genes are identified that showed statistically significant (p-value < 0.05 after Bonferroni’s correction) increased (red boxes) or decreased (green boxes) expression in individual disease cohorts relative to CTRL subjects.
