(Submitter supplied) Epithelial cells play an important role in the protection of the colon mucosa from the resident microbiota and are involved in the initiation and maintenance of intestinal inflammation. LMD is a technique that allows the extraction of specific cell types, such as colonic epithelial cells, to analyse gene expression. LMD of colon epithelial cells followed by microarray analysis could be of more value than microarray analysis of intact colon for determining which pathways are active in the colon mucosa in the early and late stages of inflammation due to increased sensitivity to changes in specific cell populations. more...

(Submitter supplied) Inappropriate response to normal intestinal bacteria is involved in the development of Inflammatory Bowel Diseases (IBD, e.g. Crohn’s Disease (CD), ulcerative colitis (UC)) and variations in the host genome may mediate this process. IL-10-/- mice develop CD-like colitis mainly in the colon, in part due to inappropriate responses to normal intestinal bacteria including Enterococcus strains. Comprehensive characterization of changes in gene expression associated with the observed inflammation in the IL-10-/- mouse model has yet to be reported. more...

(Submitter supplied) The risk for colon cancer is associated with nutrition, especially high fat and low calcium diets high in red meat. Red meat contains the iron porphyrin pigment heme, which induces cytotoxicity of the colon contents and epithelial hyperproliferation. Using a mouse model, we showed that heme caused damage to the colonic surface epithelium and induced compensatory hyperproliferation. Expression levels of heme- and stress-related genes show that heme affects surface cells and not directly crypt cells. more...

(Submitter supplied) Dietary n-3 polyunsaturated fatty acids can reduce inflammation via a range of mechanisms. This study tested the effect of dietary eicosapentaenoic acid (EPA) on intestinal inflammation using interleukin-10 gene-deficient (Il10-/-) mice. Methods: At 35 days of age, 12 weaned Il10-/- and 12 C57 mice were randomly assigned to one of two modified AIN-76A diets, supplemented with 3.7% purified ethyl esters of either EPA (n-3) or oleic acid (OA, control). more...

(Submitter supplied) Acetylation and deacetylation of histones and other proteins depend on the opposing activities of histone acetyltransferases and histone deacetylases (HDACs), leading to either positive or negative gene expression changes. The use of HDAC inhibitors (HDACi) has uncovered a role for HDACs in the control of proliferation, apoptosis and inflammation. However, little is known of the roles of specific HDACs in intestinal epithelial cells (IEC). more...

(Submitter supplied) Background & Aims: HNF4α is an important transcriptional regulator of hepatocyte and pancreatic function. Hnf4α deletion is embryonically lethal with severe defects in visceral endoderm formation, liver maturation and colon development. However, the precise role of this transcription factor in maintaining homeostasis of the adult intestine remains unclear. Herein, we aimed to elucidate the adult intestinal functions of Hnf4α. more...

(Submitter supplied) BACKGROUND: Peroxisome proliferator-activated receptor g (PPAR g) is a nuclear receptor whose activation has been shown to modulate macrophage and epithelial cell-mediated inflammation. The objective of this study was to use a systems approach for investigating the mechanism by which the deletion of PPAR g in T cells modulates the severity of dextran-sodium sulfate (DSS)-induced colitis, immune cell distribution and global gene expression. more...

(Submitter supplied) Activation of inflammatory pathways in human IBD IL-6:STAT3 pathways are activated in the affected colon in IBD. However, the functional implications of this are not known. We hypothesized that pro-inflammatory IL-6:STAT3 dependent networks would be up regulated in the colon of pediatric patients with Crohn Disease (CD) and Ulcerative Colitis (UC), and that these would regulate leukocyte survival, proliferation, and recruitment to the gut. more...

(Submitter supplied) Histone deacetylases (Hdac) remove acetyl groups from proteins, influencing global and specific gene expression. Hdacs control inflammation, as shown by Hdac inhibitor-dependent protection from DSS-induced murine colitis. While tissue-specific Hdac knockouts show redundant and specific functions, little is known of their intestinal epithelial cell (IEC) role. We have shown previously that dual Hdac1/Hdac2 IEC-specific loss disrupts cell proliferation and determination, with decreased secretory cell numbers and altered barrier function. more...

(Submitter supplied) Abstract: Interleukin-10-deficient (Il10-/-) mice serve as a model for inflammatory bowel disease (IBD). The severity of colitis strongly depends on the inbred strain carrying the disrupted Il10 gene: C3H/HeJBir (C3) confers disease susceptibility, whereas C57BL/6J (B6) confers resistance. Genome-wide scans with microsatellite markers on segregrating backcross and F2 populations resulted in the detection of ten colitogenic quantitative trait loci (QTL). more...

(Submitter supplied) Resident human lamina propria immune cells serve as powerful effectors in host defense. Molecular events associated with the initiation of an intestinal inflammatory response in these cells are largely unknown. Here, we aimed to characterize phenotypic and functional changes induced in these cells at the onset of intestinal inflammation using a human intestinal organ culture model. In this model, healthy human colonic mucosa was depleted of epithelial cells by EDTA treatment. more...
