Analysis of colon from C57BL/6J 12-14wk-olds treated with DSS for up to 6 days. DSS model emulates clinical and histopathological features of ulcerative colitis (UC), a type of Inflammatory Bowel Disease (IBD). Results provide insight into molecular mechanisms underlying development of DSS colitis.

(Submitter supplied) 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. more...

(Submitter supplied) Temporal geneome profiling of T cell transfer colitis model T cells critically regulate clinical inflammatory bowel diseases and T cell dependent experimental colitis models have gained prominent favor as useful models to identify potential pathogenic mechanisms. The naïve CD4+CD45Rbhigh cell transfer model into recombinase activating gene-1 deficient (RAG-/-) mice induces both colitis and small bowel inflammation reflecting Crohn's disease with unclear pathogenic mechanisms. more...

(Submitter supplied) 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,

(Submitter supplied) To investigate whether the H3K27ac is involved in the development of inflammatory bowal disease. We established dextran sulfate sodium (DSS)-induced chronic colitis and performed RNA-sequencing and Chromatin Immunoprecipitation followed by NGS sequencing for H3K27ac in the mice colon tissues. We find that the global H3K27ac distribution in colon tissue had no significant difference, while on the typical-enhancers specific in the DSS group, H3K27ac signals were significantly enriched when compared with the control. more...

(Submitter supplied) Inappropriate response to normal intestinal bacteria is involved in the development of Inflammatory Bowel Diseases (IBD, e.g. Crohn’s Disease (CD), ulcerative colitis (UC)) and variations in the host genome may mediate this process. IL-10-/- mice develop CD-like colitis mainly in the colon, in part due to inappropriate responses to normal intestinal bacteria including Enterococcus strains. Comprehensive characterization of changes in gene expression associated with the observed inflammation in the IL-10-/- mouse model has yet to be reported. more...

(Submitter supplied) Background: It has been found that miR-21 is increased in colonic tissues and decreased in peripheral blood regulatory T cells (Tregs) of patients with ulcerative colitis (UC). We aimed to investigate the influence of miR-21 on Tregs function in intestinal inflammation. Methods: Various CD4+ T cell populations were flow-cytometry sorted from miR-21-/- mice and littermates (WT) utilization in T-cell transfer colitis model and suppression of T cell activation and proliferation by Tregs. more...

(Submitter supplied) Thrombospondin 1 (TSP-1) is an anti-angiogenic matricellular protein with regulatory functions in inflammation and cancer. The type 1 repeats (TSR) domains of TSP-1 have been shown to interact with a wide range of proteins that result in the anti-angiogenic and anti-tumor properties of TSP-1. To evaluate potential therapeutic effects of TSRs in inflammatory bowel disease, we conducted clinical, histological and gene microarray analyses on a mouse model of induced colitis. more...

(Submitter supplied) We characterized the transcriptional landscape of acute and chronic models of dextran sodium sulfate (DSS) and adoptive transfer (AT) colitis murine models to derive novel temporal gene expression and splicing signatures in blood and colonic tissue in order to capture dynamics of colitis remission and relapse. We show that colitis induces robust expression of minor isoforms and using machine learning, demonstrate that specific temporal gene expression and splicing signatures are highly predictive of tissue histopathology spanning blood and colonic tissue as well as various experimental sites and protocols. more...
