9 May 2019 Leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5), as an EMT inducer, is involved in the potentiation of Wnt signaling in HCC.

LGR5 is a member of the Wnt signaling pathway. Although its ligand remains elusive, it has been shown that costimulation with R-spondin 1 and Wnt-3a induce increased internalization of LGR5. LGR5 also cointernalizes with LRP6 and FZD5 via a clathrin -dependent pathway to form a ternary complex upon Wnt ligand binding.

2019-07-29 Abstract. 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. 2021-04-06 coupled receptor (GPCR) 5 (Lgr5), a Wnt target gene, modulatesWntsignalingstrengththroughbindingtoits ligand R-spondin. Also, Lgr5 has been identified as a molecular marker of self-renewing and multipotent adult stem cell populations in multiple organs during recent years, including the gut, stomach, hair follicle, These results confirmed that LGR5 can activate the Wnt/β-catenin pathway by inhibiting β-catenin phosphorylation in GSCs. Based on the previous results indicating that LGR5 can promote EMT, we assumed that LGR5 promotes EMT by activating the Wnt/β-catenin pathway.

Also, Lgr5 has been identified as a molecular marker of self-renewing and multipotent adult stem cell populations in multiple organs during recent years, including the gut, stomach, hair follicle, 2019-07-29 · Lgr5, a Wnt target gene, has been widely used as a marker of organ stem cells with self-renewal capacity [41, 79], as well as an established biomarker of cancer stem cells (e.g., colorectal cancer and mammary tumors) . Simultaneously, Lgr5 has been recently reported to be essential for B cell development. LGR5, CEACAM6 and Wnt pathways are suppressed by shCD151 in HT29 and HCT116 cells in vitro and in vivo Western blot and qRT-PCR demonstrated significantly decreased expression levels of LGR5, CEACAM6, β-catenin, Wnt3a and Wnt5a in cultured HT29 and HCT116 cells after CD151 silencing at the protein and mRNA levels, respectively ( Figure 8 ). LGR4 and LGR5 are required for Wnt/PCP signalling in Xenopus. (A,B) Rspo3 signalling requires LGR4 to induce gastrulation defects.

2015-06-01 LGR5 promotes cell mobility, tumor formation and Epithelial‐Mesenchymal Transition in breast cancer cells by activating Wnt/β‐catenin signaling. Importantly, LGR5 activation of Wnt/β‐catenin signaling is a possible mechanism to regulate breast cancer stem cell renewal. We demonstrate that LGR5 facilitates high Wnt signalling in neuroblastoma cell lines treated with Wnt3a and R-spondins, with SK-N-BE(2)-C, SK-N-NAS and SH-SY5Y cell-lines all displaying strong Wnt induction.

2019-07-29 · Lgr5, a Wnt target gene, has been widely used as a marker of organ stem cells with self-renewal capacity [41, 79], as well as an established biomarker of cancer stem cells (e.g., colorectal cancer and mammary tumors) . Simultaneously, Lgr5 has been recently reported to be essential for B cell development.

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. In addition to Lgr5 itself, expression of a subset of the Wnt target genes including Cd44, Sox9, and Sord is highly enriched in the adult stem cells.

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 deficiency leads to perinatal lethality due to gastrointestinal distension.

Its specific roles during inner ear development are just emerging, but few studies have characterized Wnt target genes. Lgr5, a member of the G protein-coupled receptor family, is a Wnt target in the gastrointestinal and integumentary systems. Lgr5 has been identified as a receptor for R-spondins, which activate the Wnt signaling pathway through an interaction between Lgr5 and frizzled-Lrp5/6. Lgr5 cells were precursors for all cells in the intestinal crypts ( Barker et al., 2007 ). Wnt signaling regulates Lgr5 expression. In the gastrointestinal and integumentary systems, Wnt signaling controls Lgr5 expression (Jaks et al. 2008; Ootani et al.

Its specific roles during inner ear development are just emerging, but few studies have characterized Wnt target genes. Lgr5, a member of the G protein-coupled receptor family, is a Wnt target in the gastrointestinal and integumentary systems. We show that the default fate of Lgr5 + ISCs is to differentiate, unless both RSPO and Wnt ligands are present. However, gain-of-function studies using RSPO ligands and a new non-lipidated Wnt analogue reveal that these ligands have qualitatively distinct, non-interchangeable roles in ISCs.

Palmitoylated Wnt ligands engage cell-surface frizzled (FZD) receptors and LRP5 and LRP6 co-receptors, enabling β-catenin nuclear translocation and TCF/LEF-dependent gene transactivation. Mutations in Wnt downstream signalling components have revealed diverse functions thought to be carried out by Wnt ligands themselves. 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 is a receptor for R-spondins (de Lau et al., 2011) that activate the frizzled-Lrp5/6 complex in conjunction with Wnt and is a marker for adult stem cells in the colon and small intestine (Barker et al., 2007).

LGR5-mediated potentiation of Wnt signaling may be an impor-tant contributor to ES initiation and maintenance, especially in RSPO-rich microenvironments like developing bone. 2013-01-27 · 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 1 2010-01-08 · The Wnt target gene Lgr5 marks stem cells in the small intestine, colon, and hair follicle. Here, we investigated Lgr5 expression in the stomach and assessed the stem cell potential of the Lgr5 +ve cells by using in vivo lineage tracing. Also, in contrast to flow-sorted Lgr5 high and low cells from AOM/DSS-induced tumors, the Wnt signaling pathway was not significantly altered in our loss-of-function experiments in cell lines, though tending to be higher in LGR5 high spheres compared with LGR5 low adherent cells (P = 0.16). 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.
