Project description:This SuperSeries is composed of the following subset Series: GSE21549: Expression profiles of EDTA-dissociated colon epithelial cells of wild-type mice and vil-Cre-Bcl9-/-/Bcl9l-/- mice. GSE21576: Expression profiles of laser dissected colon tumor samples of wild-type mice and vil-Cre-Bcl9-/-/Bcl9l-/- mice Refer to individual Series
Project description:To assess potential changes in Wnt signaling more comprehensively, EDTA-dissociated colon epithelial cells from three pools of wild-type and Bcl9/Bcl9l-mutant mice were subjected to an exploratory comparative gene expression profiling. Total RNA of three samples of EDTA-dissociated colon epithelial cells of wild-type mice and three samples of vil-Cre-Bcl9-/-/Bcl9l-/- mice, each sample consisting of material of two or three different mice, was collected and resulting amplified cDNA hybridized to Affymetrix Mouse Genome 430 2.0 arrays. Samples are labeled as follows: Genotype_PoolID _UniqueID_NumberOfMice.

Project description:Expression profiles of colon epithelial cells and tumor samples of wild-type and vil-Cre-Bcl9-/-/Bcl9l-/- mice
Project description:To investigate the impact of ablating Bcl9/Bcl9l on tumorigenesis, 6-8- week-old mice were exposed first to a single dose dimethylhydrazine (DMH, 44 mg/kg body weight), which is metabolized in the liver to carcinogenic azoxymethane (AOM), followed by 7 days oral administration of 2 % dextrane sulfate sodium (DSS) in the drinking water. This regimen results in the emergence of dysplastic adenomas, which progress to differentiated adenocarcinomas that are morphologically similar to human colorectal adenocarcinomas and typically harbor β-catenin stabilizing mutations of GSK3ß phosphorylation sites. Accordingly, these tumors present hallmarks of active Wnt signaling such as accumulation of nuclear β-catenin and expression of Wnt target genes. Total RNA of laser dissected samples from five different tumors each of two wild-type mice and three vil-Cre-Bcl9-/-/Bcl9l-/- mice was collected and resulting amplified cDNA hybridized to Affymetrix Mouse Genome 430 2.0 arrays. Samples are labeled as follows: Genotype_TumorID_MouseID_UniqueID.
Project description:The purpose of this experiment is to deep sequence transcripts in WT mice and mice lacking Lingo2, and compare gene expression in the epithelial cells of the colon between wild type and mutant mice. Colon tissue was isolated from each mouse, and epithelial cells were isolated by EDTA wash
Project description:The purpose of this experiment is to deep sequence transcripts in WT mice and mice lacking Lingo3, and compare gene expression in the epithelial cells of the colon between wild type and mutant mice. Colon tissue was isolated from each mouse, and epithelial cells were removed from the colon by washing the tissue with 5 mM EDTA + 2.5 mM DTT solution.
Project description:Microarray transcriptomic analysis of formalin-fixed, paraffin-embedded small intestinal tumors from control (Apcmin/+;Vil-Cre-/-;RhoADN/-) and DN-RhoA (Apcmin/+;Vil-CreTG/-;RhoADN/-) mice.
Project description:Purpose : The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) of colon samples of intestinal epithelial cell specific Axin1 Knockout mice and WT controls that were submitted to DSS-induced colitis and AOM/DSS-induced colorectal carcinogenesis. Methods : DSS-induced colitis was performed on Axin1flfl (WT) and Vil CreERT2;Axin1fl/fl (Axin1KOΔIEC) mice by giving 3% DSS dissolved in drinking water for 7 days and subsequently placed on regular water for recovery before sacrifice at Day 7 and D13. Methods : AOM/DSS-induced colorectal tumorigenesis was performed on Axin1flfl (WT) and Vil CreERT2;Axin1fl/fl (Axin1KOΔIEC) mice that were sacrificed at day 100 post-AOM injection to collect colorectal tumors. Methods : Colonic mRNA profiles of WT and Axin1KOΔIEC mice were generated by deep sequencing using Illumina NextSeq 500 instrument (150base-lengths read V2 chemistry in a paired-end mode)
