ChIP-sequencing of the H3K4me1/2 in crypts from mice intestinal epithelium with intestinal epithelium specific LSD1 knock out compared to wild type

ABSTRACT: 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 H3K4me1/2 levels in WT and KO small intestines, we sorted small intestinal crypt cells, fixed them, isolated chromatin, and performed ChIP using an H3K4me1 and an H3K4me2 antibody as described in the protocols.

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]

Project description:Transcriptome analysis was used to investigate the global stress response of the Gram-positive bacterium Bacillus subtilis caused by overproduction of the well-secreted AmyQ α-amylase from Bacillus amyloliquefaciens. Analyses of the control and overproducing strains were carried out at the end of exponential growth and in stationary phase, when protein secretion from B. subtilis is optimal. Among the genes that showed increased expression were htrA and htrB, which are part of the CssRS regulon that responds to high-level protein secretion and heat stress. The analysis of the transcriptome profiles of a cssS mutant compared to the wild-type, under identical secretion stress conditions, revealed several genes with altered transcription in a CssRS-dependent manner, for example citM, ylxF, yloA, ykoJ and several genes of the flgB operon. However, a high affinity CssR-binding was only observed for htrA and htrB, and possibly for citM. In addition, the DNA macroarray approach reveal that several genes of the sporulation pathway are downregulated by AmyQ overexpression, and a group of motility-specific (σD-dependent) transcripts were clearly upregulated. Subsequent flow cytometric analyses demonstrate that upon overproduction of AmyQ as well as a non-secretable variant of the α-amylase, the process of sporulation is severely inhibited. The same experiments were implemented to investigate the expression levels of the hag promoter, a well-established reporter for σD-dependent gene expression. This approach confirmed the observations based on our DNA macroarray analyses and led us to conclude that expression levels of several genes involved in motility are maintained at high levels under all conditions of α-amylase overproduction. Secretion stress was applied by overproducing the well-secreted AmyQ α-amylase (pKTH10 vector) from B. amyloliquefaciens. Besides examining secretion stress in wild-type cells, we compared transcriptome profiles of a cssS mutant strain under conditions of high-level AmyQ production. Samples for transcriptome analyses were collected at the late exponential growth stage (one hour before the transition point) and 3 hours upon entry in the stationary growth phase. Three independent cultures of each strain were used and cells were sampled for macroarray experiments. Duplicate spots were averaged in Array-Pro software (Media Cybernetics, Inc.) and the signal was normalized after background subtraction by calculation of the percentage of total signal per gene using Microsoft Excel.

Project description:Prostaglandin E2 (PGE2) is involved in several inflammatory conditions including periodontitis. The aim of this study was to investigate the global gene expression profile of tumor necrosis factor alpha (TNFalpha) stimulated human gingival fibroblasts, focusing on signal pathways related to PGE2 production and the new PGE2-synthesizing enzymes, prostaglandin E synthases (PGES). The expression of microsomal prostaglandin E synthase-1 (mPGES-1) as well as the upstream cyclooxygenase-2 (COX-2) was up-regulated by TNFalpha, accompanied by increased PGE2 production. In contrast, the expression of microsomal prostaglandin E synthase-2 (mPGES-2) and cytosolic prostaglandin E synthase (cPGES) was unaffected by TNFalpha. Using microarray analysis in a time-course factorial design including time points 1, 3 and 6 h, we identified differentially expressed genes in response to TNFalpha treatment. Enrichment analysis of microarray data identified two positively regulated signal transduction pathways: c-Jun N-terminal kinase (JNK) and Nuclear Factor-kappaB (NF-kappaB). We used specific inhibitors and phosphorylation analysis to confirm their role in PGE2 regulation. Both JNK and NF-kappaB inhibitors reduced the TNFalpha-stimulated up-regulation of mPGES-1 and COX-2 as well as subsequent PGE2 production. The novel finding that TNFalpha-stimulated mPGES-1 is regulated by JNK suggests this kinase as a potential future target for treatment strategies in inflammatory disorders, including periodontitis. Keywords: Time course, gene expression, factorial design. Three human gingival fibroblast cell lines were established from gingival biopsies obtained from 3 healthy patients, 3 to 12 years of age, with no clinical signs of periodontal disease. Cells were incubated with or without TNF-alpha (20 ng/ml) for 1, 3 or 6h. After incubation for 1, 3 or 6 h in the two conditions, the cells were immediately frozen in liquid nitrogen and then stored at -70°C for subsequent isolation of total RNA. The experimental design of the microarray study was set up as a time-course factorial design, to best observe the TNF-alpha induced gene expression changes over time. C++ program (G.F. Glonek, P.J. Solomon, Factorial and time course designs for cDNA microarray experiments, Biostatistics 5 (2004) 89-111) was used to determine the exact layout of the design in order to estimate the interaction effect between treatment and time, i.e. genes that are differentially expressed over time, with optimal statistical efficiency. Cyanine 5 and cyanine 3 were used for labeling. For each cell line 12 hybridizations were performed in a time-course factorial design. In total, 36 hybridizations were performed.
