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:Activation of inflammatory pathways in human IBD. Leukocyte recruitment pathways including those for eosiniphils are activated in the affected colon in IBD. However, the functional implications of this are not known. We hypothesized that pro-inflammatory eotaxin (CCL11) dependent networks would be up regulated in the colon of pediatric patients with Ulcerative Colitis (UC), and that these would regulate eosinophil recruitment to the gut. These experiments tested differential colon gene expression relative to these pathways in healthy and UC samples. Colon biopsy samples were obtained from UC patients at diagnosis, 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 a leukocyte recruitment network which includeds CCL11 is up regulated in pediatric UC at diagnosis. The degree of up regulation of these genes compared to healthy controls was remarkably conserved within the UC patient group, suggesting common mechanisms of mucosal inflammation. These experiments tested differential colon gene expression relative to these pathways in healthy and UC samples. Keywords: Single time point in UC and healthy controls. Colon RNA was isolated from biopsies obtained from UC at diagnosis 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 1,2,4,5) used for ormalization of the Sample VALUEs are also contained within this data set.

Project description:- Background: Optimized diets during the first period of life may be most effective for improving gut and overall health. Here, we set up an interdisciplinary research pipeline to evaluate gut health benefits of early life nutrition ingredients through advanced integration of in vitro and modeling technologies that represent the infant gut environment. - Methods: In our InTESTine platform (TM), biopts of piglet gut tissue (Jejunum or Colon) were exposed (0-6h) to various infant/piglet-formula-milk based food matrices (-/+ prebiotics; -/+ predigestion by infant/piglet fecal microbiome). RNA expression of the piglet gut tissue biopts was measured by RNAseq. - Results: To be published in various papers. - Conclusion: To be published in various papers.

Project description:BACKGROUND & AIMS: Ulcerative colitis (UC) is an inflammatory bowel disorder with unknown etiology, and given its complex nature, an in vivo model to study its pathophysiology is vital. Animal models play an important role in molecular profiling necessary to pinpoint mechanisms that contribute to human disease. Thus, we aim to identify common conserved gene expression signatures and differentially regulated pathways between human UC and a mouse model hereof, which can be used to identify UC patients from healthy individuals and to suggest novel treatment targets and biomarker candidates. METHODS: Therefore, we performed high-throughput total and small RNA sequencing to comprehensively characterize the transcriptome landscape of the most widely used UC mouse model, the dextran sodium sulfate (DSS) model. We used this data in conjunction with publicly available human UC transcriptome data to compare gene expression profiles and pathways. RESULTS: We identified differentially regulated protein-coding genes, long non-coding RNAs and microRNAs from colon and whole blood of UC mice and further characterized the involved pathways and biological processes through which these genes may contribute to disease development and progression. By integrating human and mouse UC datasets, we suggest a set of 51 differentially regulated genes in UC colon and blood that may improve molecular phenotyping, as well as aid in treatment decisions, drug discovery and the design of clinical trials. CONCLUSION: Global transcriptome analysis of the DSS-UC mouse model supports its use as an efficient high-throughput tool to discover new targets for therapeutic and diagnostic applications in human UC through identifying relationships between gene expression and disease phenotype.
