10X-single cell seq of IEC and Stroma during recovery after DSS colitis in B cell sufficient/deficient mice

ABSTRACT: B cells expand during the recovery after DSS-induced colonic inflammation and might play a role in influencing tissue repair. To analyze the impact B cells might have on intestinal epithelial cells and stromal cells during recovery after intestinal injury the transcriptional profile of these mice was analysed in mice depleted of B cells and control mice on day 14 after DSS colitis.

Single cell RNAseq of mouse colon stroma during chronic DSS and homeostatic condition

Project description:We implemented a murine model of intestinal inflammation based on oral administration of multiple cycles of low dose dextran sulfate sodium (DSS) to induce epithelial injury and ECM deposition. Mice were subjected to 3 repetitive cycles of DSS displayed progressive accumulation of immune cell infiltrates associated with excessive deposition of collagen fibers. Lamina propria cells from water-fed and DSS-fed mice were isolated using enzymatic digestion, and enriched for stromal cells by FACS using antibodies excluding hematopoietic cells (CD45), epithelial cells (EpCAM), and erythrocytes. Prepared single cell suspensions were then profiled using the 10x Chromium V2 droplet-based single cell RNA sequencing platform. Tissues were collected from proximal and distal colon.

mRNA transcriptome sequencing of wild type (WT) and intestinal epithelial cell specific Axin1 Knockout mice (Axin1KOΔIEC) that have udergone DSS-induced colitis and AOM/DSS-induced colorectal tumorigenesis

Project description:Purpose : The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) of colon samples of intestinal epithelial cell specific Axin1 Knockout mice and WT controls that were submitted to DSS-induced colitis and AOM/DSS-induced colorectal carcinogenesis. Methods : DSS-induced colitis was performed on Axin1flfl (WT) and Vil CreERT2;Axin1fl/fl (Axin1KOΔIEC) mice by giving 3% DSS dissolved in drinking water for 7 days and subsequently placed on regular water for recovery before sacrifice at Day 7 and D13. Methods : AOM/DSS-induced colorectal tumorigenesis was performed on Axin1flfl (WT) and Vil CreERT2;Axin1fl/fl (Axin1KOΔIEC) mice that were sacrificed at day 100 post-AOM injection to collect colorectal tumors. Methods : Colonic mRNA profiles of WT and Axin1KOΔIEC mice were generated by deep sequencing using Illumina NextSeq 500 instrument (150base-lengths read V2 chemistry in a paired-end mode)

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

Colon gene expression signatures in wild type and Card9-/-mice exposed to DSS induced colitis

Project description:It is crucial to decipher the host-microbiota interactions as they are involved in intestinal homeostasis and diseases. Caspase Recruitment Domain 9 (Card9) is an inflammatory bowel disease (IBD) susceptibility gene coding for an adapter protein for innate immunity toward many microorganisms. Card9 mediates colitis recovery via interleukin 22 pathway activation and Card9-/- mice have enhanced susceptibility to colitis. To reveal the mechanisms responsible of this defect in Card9-/-mice, we compared colon transcriptomics in WT and Card9-/- mice before and during DSS-induced colitis. Mice transcriptomes clusterized according to the genotype supporting a pattern clearly different in WT and Card9-/- mice. The number of up-regulated genes at day 7 was largely higher in Card9-/- compared to WT mice. Pathway analyses of the induced transcripts showed a dominance of immune-related pathway with a stronger signal in Card9-/- mice. Interestingly, NOD-like receptor signaling pathway, in which CARD9 is involved, was an exception with weaker activation in Card9-/- than in WT mice. During the recovery period at day 12, pathways involved in cell proliferation and replication were significantly activated in WT compared to Card9-/- mice confirming the healing defect in Card9-/- mice. For the induction of colitis, mice were given drinking water supplemented with 2% (w/v) Dextran sulphate sodium (DSS) for 7 days, then allowed to recover by drinking water alone for 5 additional days. 3 mice of each groups (WT and Card9-/-) were sacrified before DSS administration. 5 WT mice and 4 Card9-/- mice were sacrified 7 days after DSS administration and 5 mice of each group were sacrified at day 12.

10X-single cell seq of B cells during colitis (d0 and d14)

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.

RNA-seq analysis of colonic intestinal epithelial cells (IECs) isolated from naive wild-type C57BL/6 mice, DSS-treated wild-type C57BL/6 mice, Il10-/- C57BL/6 mice and Il10-/- C57BL/6 mice with IEC-specific Rabgef1 deletion

Project description:The aim of this study is to compare the transcriptomic profile of colonic intestinal epithelial cells (IECs) at steady-state, and in several models of colitis: in naive wild-type C57BL/6 mice, in wild-type C57BL/6 mice treated for 7 days with 3% dextran sodium sulfate (DSS) in drinking water, in Il10-/- C57BL/6 mice and Il10-/- C57BL/6 mice with IEC-specific Rabgef1 deletion. Colonic IECs were isolated and FACS-sorted, then subjected tu bulk RNA-seq.

DSS Microbiota LC-MS/MS

Project description:In the DSS-induced colitis model, the epithelial damage and resulting inflammation is restricted to the colon, with a potential influence on the microbial composition in the adjacent cecum. Several studies have reported changes of the gut microbiota in the DSS-induced colitis model and other mouse models of IBD. Furthermore, metaproteomics analysis of the gut microbiome in a mouse model of Crohn’s disease demonstrated that disease severity and location are microbiota-dependent, with clear evidence for the causal role of bacterial dysbiosis in the development of chronic ileal inflammation. We have developed a refined model of chronic DSS-induced colitis that reflects typical symptoms of human IBD without a risky body weight loss usually observed in DSS models [Hoffmann et al., submitted]. In this study, we used metaproteomics to characterize the disease-related changes in bacterial protein abundance and function in the refined model of DSS-induced colitis. To assess the structural and functional changes, we applied 16S rRNA gene sequencing and metaproteomics analysis of the intestinal microbiota in three different entities of the intestinal environment, i.e. colon mucus, colon content and cecum content.
