(Submitter supplied) Chronic inflammation is a well-known risk factor but the early events by which inflammation promotes colitis-associated cancer (CAC) are still poorly understood. Here we developed a new model to profile early carcinogenesis, using mice deficient for the tumor suppressor ‘Mutated in colorectal cancer’ (MCC). We generated mice with loss of MCC expression in colonic/intestinal epithelial cells (MccΔIEC) and gave them a diet containing the drug sulindac, which acts as a mild irritant in the mouse proximal colon causing foci of tissue damage with chronic inflammation. more...

(Submitter supplied) P53 induced Mir34a is a tumor suppressor microRNA that plays important roles in cancer related processes such as proliferation, invasion and metastasis. Simultaneous loss of Mir34a and p53 is often observed in CRC. Here we show that, combined deletion of Mir34a and p53 has synergistic effects in suppressing tumor initiation, progression, invasion and metastasis in CRC by using mice lacking Mir34a and p53 in their intestinal epithelium. more...

(Submitter supplied) By using a model of inflammation-induced carcinogenesis the effects of TSP-1 in induced tumors were analyzed. Mice received a single injection of azoxymethane (AOM) and multiple cycles of dextran sodium sulfate (DSS) for inducing chronic inflammation-related cancers. Proliferation and angiogenesis status were analyzed as well as their transcript profile by using a gene microarray approach. We used Affymetrix GeneChips to determine the changes in the genetic profile between WT and TSP-1 deficient tumors in a model of colorectal carcinogenesis. more...

(Submitter supplied) Polycomb group (PcG) proteins are epigenetic silencers whose dysregulation is frequently linked to cancer via mechanisms that remain unclear. Using conditional knock-out mice in a colitis-associated colorectal cancer (CAC) model, we found that Bmi1 and Mel18 are important initiation and maintenance factors during CAC tumorigenesis. Epithelial depletion of both Bmi1 and Mel18, but not either gene alone, significantly reduces tumor growth and multiplicity. more...

(Submitter supplied) Mutations in TGFBR2, a component of the transforming growth factor (TGF)-β signaling pathway, occur in high-frequency microsatellite instability (MSI-H) colorectal cancer (CRC). In mouse models, Tgfbr2 inactivation in the intestinal epithelium accelerates the development of malignant intestinal tumors in combination with disruption of the Wnt-β-catenin pathway. However, no studies have further identified the genes influenced by TGFBR2 inactivation following disruption of the Wnt-β-catenin pathway. more...

(Submitter supplied) Canonical Wnt signaling output is mediated by β-catenin, which interacts with LEF/TCF transcription factors and recruits a general transcriptional activation complex to its C-terminus. Its N-terminus binds BCL9/9L proteins, which bind co-activators that in mammals contribute to fine-tuning the transcriptional output. We found that a BCL9/9L-dependent gene expression signature was strongly associated with patient outcome in colorectal cancer and that stem cell and mesenchymal genes determine its prognostic value. more...

(Submitter supplied) Analysis of the cystic fibrosis gene Cftr in the colon and small intestine of Cftr-deficient murine model. The hypothesis was loss of Cftr altered expression of genes important in intestinal homeostasis and oncogenic signaling pathways. The results identified potential roles of Cftr in up- or down-regulating major gene clusters that belong to groups of immune response, ion channel, intestinal stem cell and other growth regulators.

(Submitter supplied) To clarify the function of cyclin A2 in colon homeostasis and colorectal cancer (CRC) we generated mice deficient for cyclin A2 in colonic epithelial cells (CEC). Colons of those mice displayed architectural changes in the mucosa, and signs of inflammation as well as an increased proliferation of CEC associated with the appearance of low- and high-grade dysplasia. The main initial events triggering those alterations in cyclin A2 deficient CEC appear to be abnormal mitoses and DNA damage. more...
