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.

Expression data from WT, E2f8 KO, Rb KO and Rb;E2f8 DKO spleen Ter19+CD71high sorted cells

Project description:To understand molecular mechanisms underlying the synergy of Rb loss and E2F8 loss, we used gene expression profiling to assess molecular changes in Mx1-Cre-mediated knockout (KO) mice using RNA isolated from sorted Ter119+CD71high Erythroblasts. The top four upregulated and enriched pathways in the DKO mice included DNA replication, DNA damage response, DNA repair, and RNA processing. Interestingly, the majority of upregulated genes in the enriched sections of the four shared pathways contain E2f binding site(s) in their promoters, suggesting that Rb and E2F8 largely repress those genes through the E2f binding sites. Collectively, our data suggest that Rb and E2F8 co-regulate E2F-responsive genes. Spleen Ter119+CD71high cells were sorted from WT, E2f8 KO, Rb KO and E2f8;Rb DKO mice

Expression profiles of CD45+ cells in colon lamina propria from macrophage-specific E4BP4 transgenic mouse

Project description:Purpose: The goals of this study are to confirm the hypothesis that E4BP4 regulates colon specific anti-inflammatory macrophage. Methods: We generated transgenic mice (TG) with macrophage-specific E4BP4 overexpression. CD45+ cells in colon lamina propria were isolated at Zeitgeber Time (ZT) 0 from TG mice and WT littermates during the recovery period of dextran sulfate sodium (DSS)-induced colitis, and total RNA was extracted. CD45+ cells in colon lamina propria RNA profiles were generated by deep sequencing for two groups with one mouse sample each. Results: There were significant differences between TG and WT mice. Conclusions: E4BP4 increased the number of M2 macrophage population and upregulated anti-inflammatory genes.

Molecular signatures of CD45+ cells from brain and spleen after intracerebral hemorrhage

Project description:Leukocyte infiltration accelerates brain injury following intracerebral hemorrhage (ICH). But the involvement of T lymphocytes in this process has not been fully elucidated.To further depict the landscape of the composition and functional states of brain-infiltrating immune cells following ICH, single-cell RNA sequencing was performed to compare the molecular characteristics of CD45+ cells from brain and spleen tissues in ICH and control mice.Our results revealed that brain-infiltrating T cells exhibited enhanced pro-inflammatory and pro-apoptotic signatures.

mRNAs and miRNAs expression data from AOM/DSS, AOM, DSS and control mouse colon epithelial tissue at day100 when tumor formed in AOM/DSS bearing mice --- miRNA microarray

Project description:To find out which miRNAs are significantly differential expression and potentially involved in the process of inflammation promoting carcinogenesis of colorectal cancer (CRC). We established a colitis-associated CRC (AOM/DSS, Azoxymethane/Dextran sulfate sodium salt) model, colitis (DSS) model and high dose carcinogen (AOM, about 5 times AOM amount given than AOM/DSS model) model. At day 100 when tumor formed in AOM/DSS bearing mice (colitis-associated CRC mice) but no tumor was found in AOM (high dose carcinogen) and DSS model, we employed miRNA microarray as a discovery platform to identify genes with the potential to involve in the progression of CRC promoted by inflammation. 5-7 weeks female BALB/c mice, (1) AOM/DSS group: AOM 12.5mg/kg i.p. at day 1, DSS drinking 5d/21dx3circles from day 5; (2) AOM group: AOM 10mg/kg i.p. 1/weekx6 from day 1; (3) DSS group: DSS drinking 5d/21dx3circles from day 5. The distal colon epithelial tissues were collected at day100 when tumor formed in AOM/DSS bearing mice. The miRNA microarray experiments were performed together.
