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

Project description:Polycomb-mediated gene repression plays an important role in adult stem cell maintenance. Direct targets of the Polycomb repressive complex PRC2 in th intestinal epithelium were revealed by performing ChIP-sequencing on crypt samples isolated from wild type murine small intestines. The resulting list of H3K27me3-enriched genes were compared with RNA-sequencing data from wild type and Eed knockout crypts. Crypts were isolated from wild type murine intestinal epithelium and subjected to ChIP using anti-H3K27me3 and anti-H3K27Ac antibodies, after which DNA isolated from extracted immunocomplexes was sequenced.

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.

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.

ChIP-seq of CREPT in intestinal crypts

Project description:CREPT was demonstrated as a key regulator of intestinal stem cells. To figure out the role of CREPT on transcription level, a ChIP-seq experiment was performed to identify the CREPT down-stream genes in intestinal crypt cells.

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

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.

Ascl2 acts as an R-spondin/Wnt responsive switch to control stemness in intestinal crypts [ChIP-seq]

Project description:Wnt signals control three functions of intestinal crypts: maintenance of Lgr5 stem cells, proliferation of transit-amplifying daughters and formation of Paneth cells. Here, we study how the Wnt effector Î²-catenin/Tcf4 cooperates with the Wnt-activated transcription factor Ascl2 to control a stem cell transcription program. DNA elements that are co-occupied and synergistically regulated by Ascl2 and Tcf4 specifically map to stem cell genes. In vitro, Tcf4-/- mini-guts are rescued by Ascl2 expression, while Ascl2-/- organoids are rescued by Wnt signaling. A direct auto-activatory loop leads to an on/off expression pattern of Ascl2 with a threshold that depends on the previous state. Wnt/R-spondin1 activates this loop. This mechanism interprets Wnt levels in crypts and translates this continuous signal into a discrete Ascl2 âonâ or âoffâ decision. In turn Ascl2, together with Î²-catenin/Tcf, activates stem cell genes. Thus, Ascl2 forms a transcriptional 'stemness switch' that is both Wnt-responsive and Wnt-dependent Examination of Tcf4, B-catenin and Ascl2 DNA occupancy in murine intestinal organoids and human colorectal cancer cell lines *** Original raw files unavailable due to loss during backup ***

Retrograde movements determine effective stem cell numbers in intestinal crypts

Project description:Our goal was to compare the transcriptomic profile of lgr5+ high, medium and low cells (corresponding to centre, border and >3 row in crypts) between small and large intestine in mice. We observed differences in the transcriptional profile between centre and border Lgr5+ cells within small and large intestinal crypts and more profound differences between the two intestinal sites.
