The treatment experiment was performed in an intracranial orthotopic xenograft model by knockdown of LGR5 or by using the Wnt/β-catenin pathway inhibitor Wnt-C59. LGR5 expression was determined in 268 glioma specimens by immunohistochemistry. Results. LGR5 + cells possessed stronger stemness properties compared to LGR5 − cells.

LGR4 and LGR5 bind the R-spondins with high afﬁnity and mediate the potentiation of Wnt/β-catenin signaling by enhancing Wnt-induced LRP6 phosphorylation. Interestingly, neither receptor is coupled to heterotrimeric G proteins or to β-arrestin when stimu-lated by the R-spondins, indicating a unique mechanism of action.

These lines represent MYCN-amplified, NRAS and ALK mutant neuroblastoma subtypes respectively. LGR4 and LGR5 are new regulators of Wnt and R‐spondin signalling.

The Wnt target gene Lgr5 (leucine-rich-repeat-containing G-protein-coupled receptor 5) marks actively dividing stem cells in Wnt-driven, self-renewing tissues such as small intestine and colon, stomach and hair follicles. A three-dimensional culture system allows long-term clonal expansion of single … Lgr5 was originally discovered as a common Wnt target gene in adult intestinal crypts and colon cancer. It was subsequently identified as an exquisite marker of multiple Wnt-driven adult stem cell types. Lgr5 and its homologs, Lgr4 and Lgr6, constitute the receptors for R-spondins, potent Wnt signal enhancers and stem cell growth factors. The Wnt target gene Lgr5 has been recently identified as a novel stem cell marker of the intestinal epithelium and the hair follicle.

The encoded protein is a receptor for R-spondins and is involved in the canonical Wnt signaling pathway.

15 Jun 2018 Leucine rich repeat G–protein coupled receptor 5 (Lgr5) is a Wnt pathway receptor that serves as a molecular determinant of stem cells with its

Lgr5 was originally discovered as a common Wnt target gene in adult intestinal crypts and colon cancer. It was subsequently identified as an exquisite marker of multiple Wnt-driven adult stem cell types.

LGR5 hade redan fått berömmelse som en markör för proliferering av intestinala stamceller och är en Wnt-målgen 10 . LGR4 / 5 via deras aminoterminala region

LGR5 associates with Wnt-receptors and act as R-spondin receptor thereby playing a central role in the modulation of Wnt/β-catenin signaling in normal and neoplastic stem cells. Most studies in epithelial cells suggest a role of Lgr5 as potentiator of WNT-signaling. However, Cre-mediated deletion of Lgr5 in B cells caused cell death in parallel with massive accumulation of nuclear b-catenin.

Lgr5, a member of the G protein-coupled receptor family, is a Wnt target in the gastrointestinal and integumentary systems. Although its function is unknown, its defi- ciency leads to perinatal lethality due to gastrointes- tinal distension. The Wnt target gene Lgr5 has been recently identified as a novel stem cell marker of the intestinal epithelium and the hair follicle. In the intestine, Lgr5 is exclusively expressed in cycling crypt base columnar cells.
