(Submitter supplied) The intestinal epithelium is continuously renewed by a pool of intestinal stem cells expressing Lgr5. We show that deletion of the key autophagy gene Atg7 affects the survival of Lgr5+ intestinal stem cells. Mechanistically, this involves defective DNA repair, oxidative stress, and altered interactions with the microbiota. This study highlights the importance of autophagy in maintaining the integrity of intestinal stem cells.

(Submitter supplied) Intestinal stem cells are required for proliferation, differentiation, and regeneration of the intestinal epithelium. Krüppel-like factor 5 regulates intestinal stem cells in both physiologic and pathological conditions and may be a treatment target in certain diseases of the intestine.

(Submitter supplied) The essential functions of intestinal stem cells (ISCs) are to self-renew and give rise to progenitors that subsequently differentiate to absorptive or secretory cells, thus maintaining homeostasis in the intestinal epithelium. In this study, we analyzed the transcriptomic and epigenetic changes of ISCs with Klf5 deletion to understand the role of KLF5 in ISC identity and functions.

(Submitter supplied) The effort to better understand intestinal stem cell (ISC) identity and regulation remains a challenge. We have been studying the RNA-binding protein MEX3A as a putative ISC marker. In that context, we have generated the first Mex3a knockout (KO) mouse model and show MEX3A is crucial for maintenance of the Lgr5+ ISC pool. As part of a phenotypic characterization pipeline, we have performed transcriptomic profiling (RNA-sequencing) of isolated Mex3a KO small intestinal crypts and compared it against small intestinal crypts isolated from age-matched wild-type controls.

(Submitter supplied) The intestinal epithelium is continuously regenerated by highly proliferative Lgr5+ intestinal stem cells (ISCs). The existence of a population of quiescent ISCs has been suggested yet its identity and features remain controversial. Here we describe that the expression of the RNA-binding protein Mex3a labels a subpopulation of Lgr5+ cells that divide less frequently and contribute to regenerate all intestinal lineages with slow kinetics. more...

(Submitter supplied) To follow the changes in the transcriptional programs accompanying the specification of the embryonic Lgr5+ cells we sequenced whole transcriptomes of embryonic intestinal epithelium progenitors (at E13.5 and E15.5). EpCAM positive embryonic gut epithelium was isolated from dissected small intestines using fluorescence activated cell sorting (FACS). Lgr5+ progenitors were purified on the basis of GFP fluorescence from Lgr5GFP-Cre-ERT mice (Barker et al. more...

(Submitter supplied) Purpose: Transcriptomic exploration for the identification of genes induced upon TGR5 stimulation in intestinal stem cells Methods: For each biological replicate, GFPhi cells were isolated by FACS from intestines from 4 pooled Lgr5-eGFP-IRES-CreERT2 mice. About 200.000 GFPhi cells were then embedded in Matrigel (20.000 per well in 10µL Matrigel drop) and after 4 hours were treated with INT-777 (30µM) or DMSO as control. more...

(Submitter supplied) Hippo signalling has been implicated as a key regulator of tissue regeneration. In the intestine, ex vivo organoid cultures model aspects of crypt epithelial regeneration. Therefore in order to uncover the Yap regulated transcriptional programs during crypt regeneration we performed RNA-sequencing of Yap wt and Yap deficient organoids, as well as organoids inducibly expressing Yap.

(Submitter supplied) Arid1a, a subunit of the SWI/SNF chromatin remodeling complex, have been reported in multiple human cancers, however, its functional role in intestinal homeostasis remains unclear. To investigate the role of Arid1a in murine intestine, we have employed ChIP experiments in intestinal spheroid cells generated from crypt cells of wild type mice. ChIP assay revealed that Arid1a binds directly to the Sox9 promoter to support its expression.

(Submitter supplied) We show that ribosome collisions, induced by Rptor deletion or aminoacid starvation, causes a ZAK alpha mediated identity switch in intestinal stem cells by activating a more fetal-like stem cell signature. This switch also causes changes in metabolic profiles of the cells, which is heavily regulated by RNA translation efficiency of different group of metabolic genes. These observations originate from performing in vitro Riboseq and RNAseq in mouse intestinal organoids, and in vivo Riboseq in Lgr5 expressing intestinal stem cells from WT and Rptor.fl/fl mice.

(Submitter supplied) The currently accepted intestinal epithelial cell organization model equates crypt base columnar (CBC) cells, marked by high levels of Lgr5 expression, with the intestinal stem cell (ISC). However, recent intestinal regeneration studies have uncovered limitations of the ‘Lgr5-CBC’ model, leading to two major views: one favoring the presence of a quiescent reserve stem cell population, the other calling for differentiated cell plasticity. more...

(Submitter supplied) The small intestine has a robust regenerative capacity, and various cell types serve as “cells-of-origin” in the epithelial regeneration process after injury. However, how much each population contributes to regeneration remains unclear. Using lineage tracing, we found that Lgr5-expressing cells’ derivatives contained radioresistant ISCs crucial for epithelial regeneration in the damaged intestine after radiation. more...

(Submitter supplied) To define differences in chormatin accessibility and histome modifications in intestinal stem and epithelial cells, we performed ATAC-seq and ChIP-seq. We used RNA-sequencing to profile gene expression changes during intestinal stem cell differentiation into different cell types. We find that gene expression is correlated with the chromatin accessibility and reveals differences between intestinal stem cells types.

(Submitter supplied) The weekly turnover of the intestinal epithelium is driven by multipotent, Lgr5+, crypt base columnar cells (CBCs). In response to injury, however, Lgr5+ cells are lost but then re-emerge and are required for successful recovery. How these resurgent Lgr5+ stem cells arise is unclear. We transcriptionally profiled single cells from regenerating intestinal epithelia and identified a unique cell type we term the revival stem cell (rSC). more...
