RNA-seq of small intestinal organoids treated with an inhibitor for the epigenetic modifier LSD1

ABSTRACT: To assess the role of LSD1 in mice small intestinal epithelium, small intestinal organoids were treated with an inhibitor for LSD1 (GSK-LSD1) and compared to untreated organoids. Similar to intestinal epithelium from mice with an intestinal epithelium specific LSD1-KO, paneth cells dissappear upon GSK-LSD1 treatment. We used these sequencing data to show that these small intestinal organoids have a similar phenotype as mice epithelium without LSD1.

Intestinal epithelial homeostasis is maintained by adult intestinal stem cells, which, alongside Paneth cells, appear after birth in the neonatal period. We aimed to identify regulators of neonatal intestinal epithelial development by testing a small library of epigenetic modifier inhibitors in Paneth cell-skewed organoid cultures. We found that lysine-specific demethylase 1A (<i>Kdm1a/Lsd1</i>) is absolutely required for Paneth cell differentiation. <i>Lsd1</i>-deficient crypts, devoid of Panet ...[more]

RNA-seq of mouse small intestinal organoids with an intestinal-epithelial specific deletion of LSD1 compared to wild type

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.

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

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts and villus from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (cKO) (Villin-Cre+; Lsd1f/f) mice. This experiment uses a new Cre strain with 100% deletion efficiency. RNA was directly isolated from intestinal crypt and villus, and this was used for RNAseq. Gene expression analysis of cKO derived crypt and villus provides a spatially restricted outlook on the maturation status of the intestinal epithelium in the villi and the absence of Paneth cells in the crypt.

RNA-seq of crypt and villus cells from small intestinal epithelium from mice treated with antibiotics with an intestinal-epithelial specific deletion of LSD1 compared to wild type

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts and villus from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (cKO) (Villin-Cre+; Lsd1f/f) mice. This experiment uses a new Cre strain with 100% recombination efficiency. RNA was directly isolated from the crypt and villus, and this was used for RNAseq. Gene expression analysis of cKO derived crypt and villus provides a spatially restricted outlook on the maturation status of the intestinal epithelium in the villi and the absence of Paneth cells in the crypt. Additionally, these mice were treated with antibiotics to study epithelium intrinsic changes related to LSD1 deletion but independent of the bacterial microbiome.

RNAseq of small intestinal organoids from mice treated with the cytokines IL-13 and IL-22 for 72 hours in combination with the BMP signaling inhibitor DMH1

Project description:The intestinal epithelium is our first line of defense against infections of the gut and the plasticity in cellular differentiation of the intestinal epithelium is an important part of this response. The changes in cellular composition is driven by immune cell derived cytokines. Here we use signature cytokines of different type of immune responses applied to small intestinal organoids to model how different immune responses affect intestinal epithelial development. Simplified, IL-13 represents type II immunity against infections such as parasites and IL-22 represents type III immunity against infections such as extracellular bacterial infections. 10 ng/mL of IL-13 and IL-22 was added for 72 hours after splitting. Furthermore, we have found BMP signaling to be important in regulating the cellular differentiation induced by IL-13. We therefore added added a combination treatment with the activin receptor-like kinase 2 (ALK-2) signaling inhibitor Dorsomorphin homolog 1 (DMH1) in concentration of 5 uM. We find that ALK-2 signaling is crucial for IL-13 driven Tuft cell differentiation.

Project description:Murine small intestinal organoids were cultured in the presence or absence of 3µM inhibitor I-CBP112 (PubChem CID 90488984), which targets E1A Binding Protein P300 (Ep300) and Creb-binding protein (Crebbp, Cbp). Organoids were grown in culture media containing EGF, Noggin and R-spondin (ENR), media was changed after 48h, and organoids were harvested after 96h.

ATAC-sequencing mice small intestinal epithelium with intestinal epithelium specific LSD1 knock out compared to wild type

Project description:To study the epigenetic regulation of intestinal epithelium we focus on the role of chromatin modulators. Lysine-specific histone demethylase 1a (KDM1A, LSD1) is one of the enzymes that can erase the H3K4me1/2 mark. To assess the role of LSD1 in intestinal epithelium we studied wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (KO) (Villin-Cre+; Lsd1f/f) mice. We found that KO mice completely lack Paneth cells, and have altered stem cell characteristics compared to WT littermates. To assess genome-wide ATAC levels in WT and KO small intestines, we isolated intestinal epithelium tissue from wild type mice and LSD1 KO mice. This tissue was digested to single cells and performed ATAC seq as described in the protocols.

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.

Human small intestinal organoids grown with a specific protocol to enrich for Paneth cells were treated with an inhbitor (GSK-LSD1) for the epigenetic modulator LSD1.

Project description:To assess the role of LSD1 in human intestinal epithelium, human small intestinal organoids were treated with an inhibitor for LSD1 (GSK-LSD1) and compared to untreated organoids. The organoids were grown with specific conditions where Paneth cells are present in the organoids as similar experiments in mice show that Paneth cells disappear upon GSK-LSD1 treatment. Similar to mouse intestinal organoids, Paneth cells dissappear upon GSK-LSD1 treatment. Furthermore, we used these gene set enrichment analysis on these microarray data to show that these human intestinal organoids have a similar phenotype as mice epithelium without LSD1.
