(Submitter supplied) Expression profiling is a well established tool for the genome-wide analysis of the transcriptional activity of human neoplasia. However, the high sensitivity of this approach combined with the well-known cellular and molecular heterogeneity of cancer often result in extremely complex and extended expression signatures of difficult functional interpretation. The majority of sporadic colorectal cancer cases are triggered by mutations in the APC tumor suppressor gene leading to constitutive activation of the Wnt/b-catenin signaling pathway and adenoma formation. more...

(Submitter supplied) The majority of sporadic colorectal cancer cases are initiated by mutations in the APC tumor suppressor gene leading to constitutive activation of the Wnt/b-catenin signaling pathway and adenoma formation. Several pre-clinical models carrying germline mutations in the endogenous mouse Apc tumor supressor gene have been generated and their phenotype characterized. The predisposition of these mouse models to multiple intestinal adenomas closely resembles the FAP phenotype at the molecular, cellular and phenotypic level and may prove valuable to elucidate the molecular and cellular mechanisms underlying colorectal tumorigenesis. more...

(Submitter supplied) Background and aims: The transcription factor Stat3 has been considered to promote progression and metastasis of intestinal cancers. Methods: We investigated the role of Stat3 in intestinal tumors using mice with conditional ablation of Stat3 in intestinal epithelial cells (Stat3deltaIEC). Results: In the APCmin mouse model of intestinal cancer, genetic ablation of Stat3 reduced the multiplicity of early adenomas. more...

(Submitter supplied) The Adenomatous Polyposis Coli (APC) tumor suppressor is mutated in the vast majority of human colorectal cancers (CRC) and leads to deregulated Wnt signaling. To determine whether Apc disruption is required for tumor maintenance, we developed a mouse model of CRC whereby Apc can be conditionally suppressed using a doxycycline-regulated shRNA. Apc suppression produces adenomas in both the small intestine and colon that, in the presence of Kras and p53 mutations, can progress to invasive carcinoma. more...

(Submitter supplied) Background and Aims: Staging inadequately predicts metastatic risk in colon cancer patients. We used a gene expression profile derived from invasive murine colon cancer cells that were highly metastatic in an immunocompetent mouse model to identify colon cancer patients at risk for recurrence in a phase I, exploratory biomarker study. Methods: 55 colorectal cancer patients from Vanderbilt Medical Center (VMC) were used as the training dataset and 177 patients from the Moffitt Cancer Center were used as the independent dataset. 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) We examined the pathways that are regulated by TDO2 in APC-deficient cancer cells by analyzing gene expression profiles of APC-WT and APC-KO MC38 cells that are transduced with inducible shTDO2 constructs. This study establishs that the TDO2-Kyn-AhR axis serves a critical role in promoting APC-deficient tumor growth via cancer cell autonomous (metabolism and proliferation) and non-autonomous mechanisms (tumor immunity).

Methods: WT or Apc(Min/Min) organoids (day 3) were stimulated with IL-22 (2ng/ml) for 3 hours, and submitted for transcriptomic profiling. Results: The main function of IL-22 in small intestinal epithelial cells is to activate an antimicrobial immune response and defence against infection and stress. more...
