Project description:Epithelia of small and large intestines differ in their structures and functions. Such heterogeneity between these two epithelial tissues might be controlled by both epithelium-intrinsic and -extrinsic programs. By employing the cell transplantation technique developed in our laboratory, we investigated how adult SI epithelial cells behave when heterotopically transplanted onto colon. Then the gene expression profiles of small intestinal epithelium heterotopically transplanted onto colon and control colonic epithelium were compared. We used laser capture microdissection and microarray analysis to compare the global gene expression profiles of small intestinal epithelium in the heterotopically grafted tissues and control colonic epithelium.

We used laser capture microdissection and microarray analysis to compare the global gene expression profiles of small intestinal epithelium in the heterotopically grafted tissues and control colonic epithelium. Dissected epithelia obtained from serial sections (~ 30 sections) of each specimen were combined and then total RNA extraction was performed. After calculating RNA Integrity Number (RIN), we subjected one graft sample and one control colon sample, which showed the highest RIN value, for the following gene expression analysis.

Project description:To further understand different gene expression of miR-31 knockout mouse colon and normal colon, we have employed colonic epithelium microarray expression profiling as a discovery platform to identify different genes with miR-31 knockout mouse colon and normal colon.comparision with normal colonic epithelium,upgene is 285 and downgene is 178 in knockout group.

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we grew small intestinal organoids in vitro from mice with an epithelial specific deletion of LSD1 (Villin-Cre+; Lsd1f/f) and from wild type (Villin-Cre-; Lsd1f/f) mice. This experiment uses a new Cre strain with 100% recombination efficiency. Similar to intestinal epithelium from mice with an intestinal epithelium specific LSD1-KO, Paneth cells are not present in LSD1-KO small intestinal organoids. We used these sequencing data to show intrinsic epithelial changes in the intestinal epithelium caused by LSD1 deletion in the absence of microbiota and surrounding in vivo cell types.

Project description:The long-non-coding RNA Malat1 is abundantly expressed in all subsets of the intestinal epithelial cells (IEC). Here, we compared the transcriptome of the small intestinal and colonic epithelium of wildtype and Malat1-/- mice under steady state. We found that Malat1 is involved in IEC homeostasis, intestinal microbial balance, and regulates programs involved in intestinal cancer.

Project description:The rat models of colorectal cancer (CRC), such as the azoxymethane (AOM) cancer-inducing model, are important tools for researching cancer initiation pathways. However, there is limited understanding of the expression pathways of underlying normal rat colonic epithelium and how this relates to human colonic epithelium. The aim of this study was to study the acute effects of AOM on the gene and pathway expression of the rat's colonic epithelium, whilst contrasting the background normal global expression patterns along the length of the rat as compared to the normal human colonic epithelium. The study used microarrays to investigate global gene expression of the colonic epithelium from proximal and distal sections of AOM- and saline (normal)-treated Sprague Dawley rats. Rat gene and pathway expression patterns were then compared in-silico with human microarray data (see GSE9254 for files) from normal tissue samples originating from proximal and distal regions of the colon.

Project description:Gene expression was compared between E18.5 Gata4Gata6 double conditional knockout (cKO) small intestinal epithelium and E18.5 control mouse small intestinal epithleium. E18.5 mouse small intestine was collected from control and Gata4Gata6 double conditional knockout mice. Epithelial cells were isolated, and RNA was prepared. Affymetrix Mouse Gene 1.0 gene arrays were used to interrogate gene expression. Data was analyzed using dChip software.
