Expression data from YAP-S127A Villin-rtTA crypts

ABSTRACT: We overexpressed YAP in the intestinal epithelium by adding doxycycline to the drinking water of experimental mice. Mice were given dox for 2 days, and referred to as Tg (transgenic). Mice were given dox for 2 days, sacrificed, and crypts were isolated for RNA extraction and analyzed by Affymetrix microarrays.

A remarkable feature of regenerative processes is their ability to halt proliferation once an organ's structure has been restored. The Wnt signalling pathway is the major driving force for homeostatic self-renewal and regeneration in the mammalian intestine. However, the mechanisms that counterbalance Wnt-driven proliferation are poorly understood. Here we demonstrate in mice and humans that yes-associated protein 1 (YAP; also known as YAP1)--a protein known for its powerful growth-inducing and ...[more]

RNA-seq of intestinal crypts vs intestinal smooth muscle with a specific MMP17 deletion compared to wild-type

Project description:We wanted to assess the role of a specific smooth muscle protein (MMP17) in two different intestinal compartments, the epithelium (crypts) and the smooth muscle. To do that we isolate intestinal crypts from wild-type (WT) and knockout (KO, Mmp17-/-) mice, and obtained clean strips of smooth muscle. After muscle dissociation, we obtained RNA directly from crypts and muscle, and it was used for RNA-seq. By comparing WT and KO samples we observed a higher impact in gene expression affecting crypts, even though MMP17 is only expressed in muscle. This helped us to identify altered signaling pathways in KO crypts that linked MMP17 with SMAD4 and BMP signaling.

Gene expression profiling of Eed knockout and Ezh2 knockout small intestinal crypts [RNA-seq]

Project description:Polycomb-mediated gene repression plays an important role in adult stem cell maintenance. We knocked out (using the inducible AhCre-LoxP system) Polycomb genes Eed and Ezh2 in the intestine for 6 weeks, after which crypts - the small intestinal stem cell zone - were harvested and RNA sequenced. We found Wnt, Notch and cell cycle pathways to be affected in Eed knockout (KO) but not Ezh2 KO crypts. Direct targets of Eed were determined by comparing this data with ChIP-sequencing. Small intestinal crypt mRNA profiles of 6 weeks-induced 12 weeks old Eed KO, Ezh2 KO and WT mice (all triplicates) as well as 10 days-induced Eed KO and WT organoids (duplicates) were generated by RNA sequencing over two runs and using IlluminaHiseq2000 and Hiseq2500.

Differential gene expression in intestinal mouse crypts after loss of KLF5

Project description:To determine potential targets of KLF5 we performed RNA-sequencing on jejunal crypts isolated from Klf5-deficient and wildtype mice, using three biological replicates per genotype. We identified 1,480 genes that showed significant differential expression with at least a 2-fold difference between Klf5-deficient and wildtype (q-value â¤ 0.05) (Figure 5A; Supplementary Table 1). Klf5 expression was significantly downregulated 2.7-fold. Comparison of gene expression after loss of KLF5 in the intestine. Isolated jejunal crypts from 3 wildtype and 3 knockout animals were compared.

RNA-seq of crypt cells from mouse small intestinal epithelium with an intestinal-epithelial specific deletion of LSD1 compared to wild type crypts

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (KO) (Villin-Cre+; Lsd1f/f) mice. We dissociated crypts into single cells, and FACS sorted Epcam+ cells, to avoid immune-cell contamination. RNA was directly isolated from these sorted cells, and this was used for RNA seq. As KO crypts are different from WT crypts (KO crypts lack Paneth cells), identifying genes specifically regulated by LSD1 helps us to identify how LSD1 regulates intestinal crypt biology. Specifically, because we were able to combine this with ChIP-seq of the same cells, to identify where H3K4me1 levels (target of the histone demethylase LSD1) were different in the genome.

Genome-wide mapping of Rad21 binding sites and gene expression profiling in wild type mouse small intestinal epithelial crypts and Apc Min adenomas

Project description:To investigate the role of RAD21 in the transcriptional regulation of global gene expression at early stage of colorectal cancer developments, we peformed the genome-wide analysis to map genomic regions bound by Rad21 in normal small testinal crypts and tumors (adenomas) harvested from Apc Min/+ mice using ChIP-seq. ChIP-seq naalysis identified high confidence RAD21 binding sites unique to normal crypts or adenomas, as well as those common to both tissues. We further performed RNA-seq to profile the changes in gene expression from normal WT crypts to adenomas at the very early stage of adenomagenesis in the context of Rad21 heterozygous loss. mRNA profiles of normal small intestinal crypts (WT) and adenomas from Apc Min/+ and Apc Min/+:Rad21+/- double mutant mouse; Mapping of Rad21 genomic binding sites in normal intestinal crypts (WT) and Apc Min/+ adenomas

A gp130-induced Src/Yes-YAP Cascade Links Inflammation to Regeneration in the Mammalian Intestine

Project description:gp130Act cDNA was PCR-amplified and inserted into a plasmid containing the 12.4-kb Villin promoter. The 15.7-kb expression cassette was excised by PmeI digestion, purified, and injected into fertilized C57BL/6 oocytes to obtain founder mice, two of which transmitted the gp130Act transgene. Small intestinal crypts were isolated from WT and villin-gp130Act Tg small intestines. Total RNA was isolated from the isolated crypts using the RNeasy Mini kit (Qiagen) and used for microarray analysis.
