Project description:WTCCC2 project genome-wide case-control association study for Ulcerative Colitis (UC) using the 1958 British Birth Cohort and the UK National Blood Service collections as controls.
Project description:Ulcerative colitis (UC) is a chronic inflammatory disease of the colon with preiods of active disease followed by remission. We performed a whole-genome transcriptional analysis of colonic biopsies from patients with histologically active and inactive UC, as well as non-inflammatory controls. Ulcerative colitis patients and non-inflammatory controls were collected for RNA extraction and hybridization on Affymetrix microarrays. Inclusion criteria for UC patients were: age between 18 and 65, diagnosis of UC established at least 6 months before inclusion and exclusion of concomitant infection. Active disease was defined by endoscopic and histologic score: Mayo sub score >=2 and MATTS >=3 respectively . Inactive disease was also defined by endoscopic and histologic score: Mayo sub score =0 and MATTS <=2 respectively, and a remission state for a minimum of 5 month prior to biopsy collection, and remained inactive for at least 6 months after. Uninvolved mucosa from patients with active UC was defined as a colonic segment with completely normal endoscopic appearance, normal histology, and absence of any previous evidence of active disease. Finally, a total of 43 biopsies were analyzed: 13 healthy controls, 8 inactive UC, 7 non-involved active UC and 15 involved active UC.

Project description:This study contains multiple -omic data sets. As a follow up to a study on 40 Ulcerative Colitis patients (MSV000082094), 210 fecal samples were analyzed through proteomics using Tandem Mass Tag (TMT) MS3 quantitation. Samples include both Ulcerative Colitis and Crohn's disease patients with healthy volunteers for context. Fecal samples were also analyzed by metabolomics through LCMS2 on a Bruker Maxis qTOF.
