Relative expression of tryptophan hydroxylase-1 (TpH-1) mRNA in the rectal mucosa of patients with irritable bowel syndrome (IBS), control subjects and subjects with organic diseases with inflammation grading ≥ 2 (Inflammed organic disorders) and without inflammation (Non-inflammed organic disorders). No significant differences were detected in TpH-1 transcript levels of samples from patients with IBS as compared to controls. TpH-1 transcript levels are significantly higher in biopsies obtained from subjects with Inflammed organic disorders as compared to controls and biopsies from Non-inflammed organic disorders.
