Project description:To identify STAP-2 regulating genes modulated intestine inflammation, we conducted microarray analyses using colon tissue from pooled WT (n=3) or STAP-2-/- mice (n=3) treated with DSS for 3 days. Bioinformatic analyses revealed that STAP-2 deletion mediates insufficient immune and inflammatory reaction through altering a series of associated gene expression. The DSS-treated colons derived from WT (n=3) and STAP-2 KO (n=3) mice were examined. Each strain was run in biological duplicate.

Project description:This study aims to investigate the protein expression profiles in a murine model of dextran sulfate sodium (DSS)-induced colitis using advanced Astral-DIA quantitative proteomics technology. A total of 12 colon tissue samples were analyzed, including 6 from healthy control mice and 6 from DSS-treated mice with induced colitis. Experimental Design Species: Mus musculus (C57BL/6 strain). Tissue Source: Colon tissues were dissected, snap-frozen in liquid nitrogen, and homogenized to extract proteins. Groups: Control Group: Healthy mice without intervention. DSS Group: Mice subjected to 2.5% DSS administration for 7 days to induce colitis, validated by histopathological assessment.

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:Gene expression analysis of sorted colon macrophages of Rictor fl/fl LysM+/+ and Rictor fl/fl LysM+/cre mice Dysregulations of immune and metabolic processes can lead to chronic inflammation, which is one of the driving forces for the development of cancer. Macrophages are regulators of these processes and therefore have a fundamental role for the initiation of cancer. Here we find that deletion of Rictor in myeloid cells increases tumor number and size in the colitis-associated colorectal cancer model and leads to a stronger inflammatory response in the underlying acute DSS-colitis model. OPN is shown to be upregulated in the serum of myeloid-specific Rictor-KO mice during the DSS-colitis and the more severe phenotype, characterized by decreased survival, increased weight loss, shorter colons and enhanced infiltration of immune cells into the colon, can be reverted by the neutralization of OPN in these mice. Microarray analysis reveals a change in inflammatory and metabolic gene signatures of Rictor-KO colon macrophages that is also seen in the Rictor-KO BMDM in vitro. Therefore, our data show that myeloid Rictor controls macrophage polarization and the cellular energy metabolism, thereby suppressing colitis and colitis-associated colorectal cancer.

Project description:Primary cilia (PC) are important signaling hubs in cells and we explored their role in colorectal cancer (CRC) and colitis. In the colon we found PC to be mostly present on different subtypes of fibroblasts and exposure of mice to either chemically induced colitis-associated colon carcinogenesis (CAC) or dextran sodium sulfate (DSS)-induced acute colitis decreased PC numbers. We employed conditional knock-out strains for the PC essential genes, Kif3A and Ift88, to generate mice with reduced numbers of PC on colonic fibroblasts. These mice showed an increased susceptibility in the CAC model as well as in DSS-induced colitis. Secretome and immunohistochemical analyses of DSS-treated mice displayed an elevated production of the pro-inflammatory cytokine IL-6 in PC-deficient colons. An inflammatory environment diminished PC presence in primary fibroblast cultures. This was triggered by IL-6 as identified by RNAseq analysis together with blocking experiments, suggesting an activation loop between IL-6 production and PC loss. Notably, an analysis of PC presence on biopsies of patients with ulcerative colitis as well as CRC patients revealed decreased numbers of PC on colonic fibroblasts in pathological versus surrounding normal tissue. Taken together, we provide evidence that a decrease in colonic PC numbers promotes colitis and CRC.
