Loss of colonic primary cilia promotes inflammation and carcinogenesis

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.

Gut microbiota analysis in WT and Il17d-deficient mice treated with or without colitis

Project description:Microbiota dysbiosis has been reported to contribute to the pathogenesis of colitis, to demonstrate whether IL-17D protects against DSS-induced colitis through regulation of microflora, we performed 16S rRNA sequencing in feces from WT and Il17d-deficient mice. Our data indicate that Il17d deficiency results in microbiota dysibiosis in both steady state and DSS-induced colitis.

Vanillin Ameliorated Azoxymethane/Dextran Sodium Sulfate-Induced Murine Colorectal Cancer: the Involvement of Proteasome/Nuclear factor-κB/Mitogen-Activated Protein Kinase Pathway

Project description:Vanillin is a natural dietary flavoring. Colorectal cancer (CRC) is one of the common malignancies in the world. Chronic intestinal inflammation is a risk factor for the development of CRC. We have previously found that vanillin improves and prevents the colitis in mice. Here, we evaluated the inhibitory activities of vanillin on a mouse model of colitis-induced colon cancer.

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.

Gene expression profiling of colitis-associated and sporadic colorectal tumors in mice

Project description:To uncover molecular mechanisms specifically involved in the pathogenesis of colitis-associated colon cancer (CAC), we studied tumorigenesis in experimental models of CAC and sporadic CRC that mimic characteristics of human CRC. Using comparative whole genome expression profiling, we observed differential expression of epiregulin (Ereg) in mouse models of colitis-associated, but not sporadic colorectal cancer. Similarly, highly significant upregulation of Ereg expression was found in cohorts of patients with colitis-associated cancer in inflammatory bowel disease but not in sporadic colorectal cancer. Furthermore, tumor-associated fibroblasts were identified as major source of Ereg in colitis-associated neoplasias. Functional studies showed that Ereg-deficient mice, although more prone to colitis, are strongly protected from colitis-associated tumors, and data from serial endoscopic studies revealed that Ereg promotes growth rather than initiation of tumors.
