(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) 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) The myeloid translocation gene family member MTG16 is a transcriptional corepressor that relies on the DNA-binding ability of other proteins to determine specificity. One such protein is the ZBTB family member Kaiso, and the MTG16:Kaiso interaction is necessary for repression of Kaiso target genes such as matrix metalloproteinase-7. Using the azoxymethane and dextran sodium sulfate (AOM/DSS) murine model of colitis-associated carcinoma, we previously determined that MTG16 loss accelerates tumorigenesis and inflammation. more...

(Submitter supplied) The human C-type lectin Reg3a (HIP/PAP) is an antimicrobial peptide that kills Gram-positive bacteria. Reg3a preserves gut microbiota homeostasis, reinforces intestinal barrier function and thereby helps to fight induced colitis in mice. Transcriptomic data revealed an upregulation of numerous genes involved in the robustness of the intestinal barrier, and the biosynthesis pathway of mucin core 1 and 3 O-glycans.

(Submitter supplied) Colorectal cancer (CRC) remains the leading cause of cancer-related death in the world. Aspirin (ASA) and curcumin (CUR) are widely investigated chemopreventive candidates for CRC. However, the precise mechanisms of their action and their combinatorial effects have not been evaluated. The purpose of the present study was to determine the effect of ASA, CUR, and their combination in azoxymethane/dextran sulfate sodium (AOM/DSS)-induced colitis-accelerated colorectal cancer (CAC). more...

(Submitter supplied) The pro-inflammatory cytokine interleukin-23 (IL-23) has been implicated in colorectal carcinogenesis (CRC). Yet, the cell-specific contributions of IL-23 receptor (IL-23R) signaling in CRC remain unknown. One of the cell types that highly expresses IL-23R are colonic regulatory T cells (Treg cells). The aim of this study was to define the contribution of Treg cell-specific IL-23R signaling in sporadic and inflammation-associated CRC. more...

(Submitter supplied) To investigate the effect of the cell-of-origin on the transcriptional phenotype of the tumor, we performed bulk RNAseq on macroscopically dissected intestinal tumors from mice carrying lineage-specific Apc/Kras mutations in Paneth or ISC cells. Where indicated, tumorigenisis was triggered in an inflammatory context by administration of Dextran Sodium Sulfate (DSS).

(Submitter supplied) Although ageing is usually regarded as a high risk of cancer, the relationship between ageing stromal microenvironment and spontaneous cancer initiation is poorly understood. In murine models of DSS-induced colitis and AOM/DSS-induced colitis-associated cancer (CAC), we found ageing significantly inhibit both intestinal wound healing and simultaneous CAC initiation. In young mice, through conditional lineage tracing, a novel and important source of fibroblasts transformed from intestinal smooth muscle cells (ISMCs) was identified during intestinal wound healing, which existed persistently in CAC. more...

(Submitter supplied) Rationale: RNA binding protein 47 (RBM47) is required for embryonic endoderm development but a role in adult intestine is unknown. Objective: We studied intestine-specific Rbm47 knockout mice (Rbm47-IKO) following intestinal injury and made crosses into Apcmin/+ mice to examine alterations in intestinal proliferation, response to injury and tumorigenesis. We also interrogated human colorectal polyps and colon carcinoma tissue. more...
