Spatial transcriptomic studies of the small intestine from WT and DDX5△IEC (KO) mice

ABSTRACT: DDX5, a DEAD box containing RNA binding protein, is involved in multiple aspects of RNA metabolism and is abundantly expressed in all subsets of the intestinal epithelial cells (IEC). Here, we characterized the DDX5-dependent transcriptome in the small intestine. In the DDX5△IEC tissue, we found that secretory IEC lineage progenitor containing spots (Atoh1hi and Sox4hi) had reduced expression of Pou2f3, a master regulator of a subset of IECs called tuft cells. As a result of the loss of Pou2f3 expression in the progenitors, DDX5△IEC tissue harbored lower number of tuft cell containing spots (Dclk1hi) compare to WT tissues.

DDX5 in colonic tumors

Project description:The Asp-Glu-Ala-Asp (DEAD)-box RNA binding protein, DDX5, is ubiquitously expressed in many cell types, yet its role in RNA metabolism and its downstream function in vivo has not been fully elucidated. In the intestine, DDX5 is highly expressed in the intestinal epithelial cell (IECs) and contributes to tumorigenesis. Here, we used a conditional mouse lines where DDX5 is knocked out in IECs upon Tamoxifen administration to uncover mechanisms underlying DDX5 functions in colon tumors.

C. rodentium remodels metabolism in IEC

Project description:The mechanisms by which the mouse pathogen Citrobacter rodentium triggers effacement of the brush border microvilli, colitis, hyperplasia and dysbiosis remain poorly understood. We investigated the impact of C. rodentium infection on the proteomic and metabolic landscapes of intestinal epithelial cells (IECs) in vivo using isobaric labeling proteomics and targeted metabolomics. We found that infection depletes proteins involved in butyrate uptake, glycolysis, TCA cycle, lipid metabolism and oxidative phosphorylation with aparallel, increased production of creatine/phosphocreatine and cholesterol. The evolving ecological niche within the infected gut was concomitant with a reduction in butyrate-producing commensal bacteria and expansion of Proteobacteria that can metabolize cholesterol. These changes coincide with the modulation of IEC transcription factors by C. rodentium, specifically phosphorylation of Kdm5a, demethylation of histone H3 (Lys-4) and cleavage of Srebp2. Taken together our results show that whilst engaging with the host in a race to control innate immune responses, C. rodentium and the changing microbiota shape the metabolism flow in IECs.

RNA-seq analysis of colonic intestinal epithelial cells (IECs) isolated from naive wild-type C57BL/6 mice, DSS-treated wild-type C57BL/6 mice, Il10-/- C57BL/6 mice and Il10-/- C57BL/6 mice with IEC-specific Rabgef1 deletion

Project description:The aim of this study is to compare the transcriptomic profile of colonic intestinal epithelial cells (IECs) at steady-state, and in several models of colitis: in naive wild-type C57BL/6 mice, in wild-type C57BL/6 mice treated for 7 days with 3% dextran sodium sulfate (DSS) in drinking water, in Il10-/- C57BL/6 mice and Il10-/- C57BL/6 mice with IEC-specific Rabgef1 deletion. Colonic IECs were isolated and FACS-sorted, then subjected tu bulk RNA-seq.

BulkRNA sequencing of small intestinal IEC epithelial cells of Casp3/7ΔIEC mice and Casp3/7FL/FL littermates

Project description:Apoptosis is widely believed to be crucial for epithelial cell death and shedding in the intestine, thereby shaping the overall architecture of the gastrointestinal tract, but also regulating tolerance induction during homeostasis. To experimentally address this concept, we generated intestinal epithelial cell (IEC)-specific knockout mice that lack both executioner caspase-3 and caspase-7 (Casp3/7?IEC), which are the converging point of the extrinsic and intrinsic apoptotic pathway. Surprisingly, the overall architecture, cellular landscape and proliferation rate remained unchanged in these mice. However, non-apoptotic cell extrusion was increased in Casp3/7?IEC mice, compensating apoptosis deficiency, maintaining the same physiological level of IEC shedding. Microbiome richness and composition stayed unaffected, bearing no sign of dysbiosis. Transcriptome and single cell RNA sequences analyses of IECs and immune cells revealed no differences in signaling pathways of differentiation and inflammation. These findings demonstrate that during homeostasis apoptosis per se is dispensable for IEC turnover at the top of intestinal villi intestinal tissue dynamics, microbiome composition and immune regulation.

IEC intrinsic IL-1R signaling holds dual roles in regulating intestinal homeostasis and inflammation

Project description:Introduction: Intestinal epithelial cells (IECs) constitute a critical first line of defense against microbes by providing a physical barrier capable of producing antimicrobial peptides (AMPs) and cytokines. While IECs are known to respond to various microbial signals, the precise upstream cues regulating diverse IEC responses are not clear. Method: Mouse intestinal crypts were isolated from colon tissue. Crypts were differentiated into 3D spheroids in matrigel by stimulating with LWRN media and growth factors. After differentiation colonoids were stimulated with IL-1b, IL-22, or IL-1b and IL-22 for 12 hours then RNA was isolated for RNA sequencing. Conclusion: Transcriptional profiling of mColonoids reveals IL-1b synergizes with IL-22 to induced a unique gene profile

Characterization of the molecular signature associated with the ablation of integrin Î±6 in IECs in the Î±6ÎIEC-TAM mouse model

Project description:Transcriptome analysis of mRNAs extracted from the rectal mucosa of WT and Î±6ÎIEC-TAM mice, 15 days after tamoxifen treatment Inflammatory bowel diseases (IBD) in humans are characterized by chronic inflammation and gastrointestinal tissue damage, caused by a combination of genetic and environmental factors. We show that the specific ablation of integrin Î±6 in intestinal epithelial cells (IECs) results in spontaneous colorectal inflammation in mice. In order to characterize the earlier molecular signature involved in the onset of inflammation, we performed Affymetrix microarrays and compare control versus Î±6ÎIEC-TAM transcriptomes after tamoxifen treatment. RNAs were prepared from rectal mucosa of 3 control mice treated with tamoxifen, 4 mutant mice treated with tamoxifen and 4 mutant mice treated with NaCl. The transcriptome analysis was performed using the Affymetrix Mouse Gene 1.0 ST arrays. Images were processed using affymetrix GeneChipÂ® Command ConsoleÂ® Software (AGCC) (version 2.0) and numerical values were generated using Affymetrix Expression Consoleâ¢ Software (version 1.1).
