(Submitter supplied) There is a gradient of β-catenin expression along the colonic crypt axis with the highest levels at the crypt bottom. However, it remains unclear whether different levels of canonical Wnt signaling exert distinct roles in the colonic epithelium. In the present study, we first showed that the canonical Wnt signaling is active in the proliferative compartment of normal colonic crypts by separating actively proliferating progenitor cells from non-proliferating cells in the colon using transgenic mice expressing a histone H2B-green fluorescent protein (GFP) fusion protein under the control of a tetracycline responsive regulatory element. more...

(Submitter supplied) We have analysed transcriptional effects of BRAF(V600K) in the intestinal epithelium of transgenic mice that harbour an inducible BRAF(V600K) transgene. Mice used in this experiment were compound transgenic for a stem-cell specific Lgr5-EGFP Reporter and either an inducible TdTomato-2A-BRAF(V600K) transgene or an inducibe TdTomato-luciferase transgene.

(Submitter supplied) To assess cellular changes upon abrogation of the WNT-signaling pathway, we induced expression of a dominant-negative T-cell factor 4 (TCF4). This showed a remarkable overlap with activation of the unfolded protein response (UTR) in the same colon cancer cell line.

(Submitter supplied) To assess the effect of activation of the unfolded protein response (UPR) in colon cancer cell lines, we treated cells with the AB5 subtilase cytotoxin (SubAB). This proteolytically cleaves the 78-kDa glucose-regulated protein (GRP78; also known as HSPA5 or BiP) inside the endoplasmic reticulum. We find that the WNT signaling pathway is highly affected upon treatment with SubAB.

(Submitter supplied) We used RNA sequencing to compare the transcripts of the cochleae from control mice and from mice with β-catenin activation, Notch1 deletion, and β-catenin activation combined with Notch1 deletion in Sox2+ SCs. We identified the genes involved in the proliferation and transdifferentiation process that are either controlled by individual signaling pathways or by the combination of Wnt and Notch signaling.

(Submitter supplied) The Wnt signaling pathway is deregulated in over 90% of human colorectal cancers. β Catenin, the central signal transducer of the Wnt pathway, can directly modulate gene expression by interacting with transcription factors of the TCF/LEF-family. In the present study we investigate the role of Wnt signaling in the homeostasis of intestinal epithelium using tissue-specific, inducible beta-catenin gene ablation in adult mice. more...

(Submitter supplied) We performed 7 single-cell RNAseq experiments to identify progenitor cell populations in the small intestine. To also capture rare intestinal cell populations such as stem cells and secretory cells we not only analyzed crypt cells from wildtype mice but also used two reporter mouse lines: i) the FltpZV/+ mouse line of which we mixed live crypt cells with Fltp Venus reporter (FVR) positive cells at different ratios and ii) Foxa2-Venus fusion (FVF) reporter mice. more...

(Submitter supplied) 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 β-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. more...

(Submitter supplied) The homeostasis of the gut epithelium relies upon continuous renewal and proliferation of crypt-resident intestinal epithelial stem cells (IESCs). Wnt/β-catenin signaling is required for IESC maintenance, however, it remains unclear how this pathway selectively governs the identity and proliferative decisions of IESCs. Here, we demonstrate that C-terminally-recruited transcriptional co-factors of β-catenin act as all-or-nothing regulators of Wnt-target gene expression. more...

(Submitter supplied) The gastrointestinal epithelial crypts are clonal units with a high cell turnover, driven by a small population of long-lived, Lgr5-expressing stem cells located in the crypt base. Despite this, depletion of Lgr5+ cells does not lead to severe pathology. Instead, other cell populations, such as secretory and enterocyte precursors are able to de-differentiate, replace Lgr5+ cells, and regenerate the crypt. more...
