(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) To understand the extent of Smad-mediated gene regulation in the colon, we isolated colon epithelium from Smad4ΔLrig1 and from Smad4+ control mice (either mice lacking a CreERT allele and treated with tamoxifen, or mice bearing a CreERT allele but treated with vehicle only) and analyzed the colonic epithelium by RNAseq. The ability of TGFβ1 and/or BMP2 to block TNF-mediated induction of Ccl20 from our study suggests that these Smad-mediated pathways may act as gatekeepers for induction of other inflammation-associated genes. more...

(Submitter supplied) Wnt signaling plays a pivotal role in colorectal cancer. Intrinsic activation of Wnt by mutational events, such as mutations in the tumor suppressor gene APC, represents the most frequent initiating event in this disease background. Long truncated versions of APC retain partial functionality, which leads to a sub-maximal, “just right” activation state of Wnt signaling supposed to be beneficial for disease initiation. 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) 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).

(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...
