Colonic gene expression data of acute and chronic dextran sodium sulphate (DSS) colitis mice

Project description:The lack of suitable animal models reflecting chronically relapsing inflammation and tissue remodeling have hindered fibrosis research in inflammatory bowel diseases (IBD). This study investigated changes in connective tissue in a chronic murine model using different cycles of dextran sodium sulphate (DSS) to mimic the relapsing nature of the disease. We used whole gene expression arrays to study differences in colonic gene expression levels between acute and more chronic DSS colitis, Acute and chronic relapsing colonic inflammation was induced in C57BL6 female mice using several cycles of exposure to DSS in drinking water, followed by recovery phases. Total RNA, extracted from snap frozen colon from five mice per condition was used to analyze mRNA expression via Affymetrix Mouse Gene 1.0 ST arrays.

Colonic gene expression data of TIMP1 knock out colitis mice

Project description:Increased levels of tissue inhibitor of metalloproteinase-1 (TIMP-1) have been detected in fibrotic strictures in Crohnâs disease. In a murine model of chronic inflammation, fibrosis was associated with an increase in TIMP-1 and inhibition of matrix metalloproteinase (MMP)-mediated degradation. We investigated the effect of TIMP-1 deficiency on the colonic gene expression in acute and chronic murine models of colitis, using whole genome gene expression arrays. Colitis was induced via oral administration of dextran sodium sulphate (DSS) to B6.129S4-Timp1tm1Pds/J knock-out (KO) and C57BL/6J wild-type (WT) mice. Total RNA extracted from snap frozen colon was used to analyze mRNA expression via Affymetrix Mouse Gene 1.0 ST Arrays

Genomic profile of dextran sulphate sodium-induced colitis model in rats

Project description:Background & Aims: Dextran sulphate sodium (DSS) induced colitis in rats is one of the most widely used models of inflammatory bowel disease. Animal models can provide new insights into the pathogenesis of intestinal inflammation, which is still unknown. We have performed a genomic analysis of the DSS rat colitis including an acute and a recovery phase. Methods: Expression profile of 6 control rats were compared with colitic rats at day 1 every other day until day 23 after DSS treatment using the GeneChip Rat Genome 230 2.0 Array (Affymetrix). Functional and pathways analysis were made with the differentially expressed genes. Keywords: Time course and differentially expressed genes analysis

The effect of new probiotic mixture in DSS (dextran sulphate sodium) – induced colitis mouse model

Project description:The current study was designed to clarify signalling pathways and assess possible beneficial effect of new probiotic mixture in DSS (dextran sulphate sodium) – induced colitis mouse model. Manipulation of intestinal microbiota with probiotics represents a promising alternative or adjunct therapy in gastrointestinal disorders and inflammation. RNA extracted from the middle part of colon tissue from ~11 weeks female C57BL/6JOlaHsd mouse strain was used for examination of the global gene expression using Affymetrix GeneChip Mouse Gene 2.0 ST microarrays.

Expression data from untreated and DSS-treated Adamts12 WT and KO mice

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

Effects of dietary folic acid on methylation status of colon non-neoplastic epithelium and dysplasia in mice with colitis

Project description:Folic acid supplementation (8 mg/kg diet) promotes colon tumor formation in mice with established colitis induced by carcinogen azoxymethane (AOM) and dextran sulfate sodium sulfate (DSS). This induction of colon tumors was associated with hypomethylation of DNA cased by folic acid supplementation.

Dextran sodium sulfate treatment of wild type and Pirc rats alters colonic normal tissue gene expression

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.
