Project description:Transcription profiling by array of mouse colon tissues under dextran sodium sulphate induction for 2, 4 and 6 days against uninduced controls at day 0
Project description:Ribo-zero RNAseq experiments were carried out with mouse distal colon DSS Colitis model of genetically engineered mice. For each mouse line for: Gpsm3 (3% DSS), Aif1 (3% DSS), Nckap1l (Hem1), Dock2 (3% DSS), Dok3 (3.5% DSS) DSS treatment for five days followed by water for 5 days, (7 days for Nckap1l). Tissue was collected at Day 10 (Day 12 for Nckap1l (HEM1)).
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.
Project description:B cells expand during the recovery after DSS-induced colonic inflammation. To investigate if a specific subtype is expanding and to analyse the transcriptional profile of these cells a transcriptional analysis on single cell level was carried out. In detail, B cells were isolated from the colon of mice on day 0 (no treatment) or day 14 (recovery) after 7 days of DSS treatment by flow cytometric sorting and analyzed by 10X sequencing.
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:Expression profile of colon mucosa of F344 rats treated with 5% DSS during five days vs colon mucosa of F344 rats pre-treated for 20 days with resveratrol 1mg/kg/day and during the five days of 5% DSS administration Keywords: Inflammation experiment Two conditions experiment, colon mucosa of F344 rats treated 5% DSS for 5d vs colon mucosa of F344 rats pretreated with 1mg/kg/day resv + 5% DSS for 5d. 8 Biological samples for each group
