Project description:To investigate the expression profiles of circRNAs in colon tissues of the patients with Crohn’s Disease(CD) , ulcerative colitis (UC) and healthy controls (HC), we used circRNA microArray analysis form Arraystar to examine the expression of circRNAs in colon tissues of CD,UC and HC.

Project description:Colon gene expression in human IBD. The three major clinical subsets of Inflammatory Bowel Disease (IBD) include colon-only Crohn's Disease (CD), ileo-colonic CD, and Ulcerative Colitis (UC). These experiments tested differential colon gene expression in these three types of IBD, relative to healthy control samples, and the local degree of mucosal inflammation as measured by the CD Histological Index of Severity (CDHIS). Colon biopsy samples were obtained from IBD patients at diagnosis and during therapy, and healthy controls. The global pattern of gene expression was determined using GeneSpring software, with a focus upon candidate genes identified in a recent genome wide association study in pediatric onset IBD. Data suggested that two of these candidate genes are up regulated in pediatric IBD, partially influenced by local mucosal inflammation. These experiments tested differential colon gene expression in healthy, CD, and UC samples for candidate genes identified in a recent pediatric onset IBD genome wide association study. Keywords: Single time point in CD and UC and healthy controls.

Project description:Activation of inflammatory pathways in human IBD IL-6:STAT3 pathways are activated in the affected colon in IBD. However, the functional implications of this are not known. We hypothesized that pro-inflammatory IL-6:STAT3 dependent networks would be up regulated in the colon of pediatric patients with Crohn Disease (CD) and Ulcerative Colitis (UC), and that these would regulate leukocyte survival, proliferation, and recruitment to the gut. These experiments tested differential colon gene expression relative to these pathways in healthy, CD, and UC samples. Colon biopsy samples were obtained from CD and UC patients at diagnosis, CD patients during therapy, and healthy controls. The global pattern of gene expression was determined using GeneSpring software, and biological networks were identified using Ingenuity software. Data suggested that two IL-6:STAT3 dependent networks are up regulated in pediatric IBD both at diagnosis and during therapy which regulate leukocyte recruitment and survival. The degree of up regulation of these genes compared to healthy controls was remarkably conserved across the two CD groups and the UC groups, suggesting common mechanisms of mucosal inflammation. Keywords: Single time point in CD, UC, and healthy controls.

Keywords: Single time point in CD and UC and healthy controls. Colon RNA was isolated from biopsies obtained from CD and UC at diagnosis and during therapy and healthy controls. Samples were obtained from the most proximal affected segment of colon. Microarray experiments were performed as described in the CCHMC microarray core, and data was analyzed as described above in the summary. The '107' internal control CEL files (for batches 1,2,3,4,5) used for normalization of the Sample VALUEs are also contained within this data set.

Project description:Objective Crohn’s Disease (CD) and Ulcerative Colitis (UC) are chronic inflammatory diseases of the gastrointestinal tract. Reliable diagnosis of these diseases requires a comprehensive examination of the patient, which include invasive endoscopy. This study assesses whether non-invasive LC-MS/MS based analysis of microbial and human proteins from feces may support the diagnosis of the diseases. Design In order to mimic a representative clinical background for this study, we investigated 17 healthy controls, 11 CD patients, 14 UC patients, also 13 Irritable Bowel Disease (IBS) patients, 8 Colon Adenoma (CA) patients, and 8 Gastric Carcinoma (GCA) patients. The proteins were extracted from the fecal samples with liquid phenol in a ball mill. Subsequently, the proteins were digested tryptically to peptides and analyzed by liquid chromatography coupled to an Orbitrap MS/MS. For protein identification and interpretation of taxonomic and functional results, the MetaProteomeAnalyzer software and the UniProtKB/SwissProt database and several metagenomes from human fecal samples were used. Results Cluster analysis and ANOSIM show a separation of healthy controls from patients with CD and UC as well as from patients with GCA. Among others, UC and CD correlated with an increase of neutrophil extracellular traps and immunoglobulins G (IgG) as well as a decrease of IgA. A specific marker metaprotein for CD was an increase of the human enzyme sucrose-isomaltase. IBS and CA patient’s fecal metaproteome showed only minor alterations. Conclusion Metaproteome analysis distinguished between patients with UC, CD and healthy controls and is therefore useful as a non-invasive tool for routine diagnostics in hospitals.
