Project description:Comparison of faecal flora of three healthy individuals and a patient suffering from Ulcerative Colitis during disease and remission states. Faecal samples were taken and frozen at -80 within one hour.
Project description:Adamts12-deficient mice undergo more severe colitis than WT mice after induction with DSS. We used microarrays to determine the gene expression differences between Adamts12-deficient and WT mice during ulcerative colitis induced with DSS (dextran sodium sulfate) Fragments of distal colon from DSS-treated (2% DSS during 7 days and 1 day of recovery) and untreated Adamts12-deficient and WT mice were obtained for RNA extraction and hybridiztion with Affymetrix microarrays

Project description:Dextran sodium sulfate (DSS) causes inflammation in the gut similar to ulcerative colitis in humans. Patients with ulcerative colitis have increased risk of developing colon cancer. We sought to determine which genes are altered in the normal colonic epithelium, and which changes depend on the Pirc mutation. 97 day old (ACIxF344)F1 wild type and Pirc male rats either untreated or given 4% DSS in the drinking water from 40-47 and 54-61 days of age, housed in 12 hour light:12 dark, ad lib feeding. Normal colonic tissue was collected from the distal colon at 97 days of age.

Project description:10x Chromium single cell RNA-Seq of colonic mesenchyme cell populations in health and Ulcerative Colitis in human patients and health in DSS-induced colitis in murine colon
Project description:Dextran sodium sulfate (DSS) causes inflammation in the gut similar to ulcerative colitis in humans. Patients with ulcerative colitis have increased risk of developing colon cancer. We sought to determine whether genes altered in the normal colonic epithelium or tumor differed between sporadic and inflammation-associated tumor development.
Project description:Temporal genome profiling of DSS colitis The DSS induced mouse colitis model is often used to emulate Ulcerative Colitis (UC) in order understand pathophysiological mechanism of inflammatory bowel disease (IBD). Given the progressive nature of IBD, colon tissue gene expression changes during the evolution of disease, and knowing the changes in gene expression profiles could indentify potential diagnostic markers or additional therapeutic targets for colitis. Therefore, we performed temporal genome expression profiling analysis using the Affymetrix genome wide microarray system to identify broad scale changes in gene expression associated with the development of colitis. Keywords: Expression time course of mouse colon tissue induced by 3% DSS. C57BL/6J mice were given 3% DSS in the drinking water and tissues from individual cohorts were collected at days 0, 2, 4 and 6. Total RNA were extracted from the colon tissue and detected by Affymerix GeneChip Mouse Genome 430 2.0 Array.
