QUICK LINKS

IWR-1-endo is a potent Wnt signaling inhibitor. Since Wnt protein signaling leads to β-catenin activation, IWR-1-endo then inhibits a cell-based Wnt/β-catenin pathway reporter response. Wnt-induced accumulation of β-catenin is inhibited by IWR-1-endo, and the destruction complex is stabilized as a result. When IWR-1-endo stabilizes Axin-scaffolded destruction complexes, β-catenin phosphorylation is promoted. Additionally, IWR-1-endo promotes endothelial cell specification of cardiac progenitor cells.

Rated 5 out of 5 by from WangWang, R. et al. (PubMed 26214410) investigated the role of musculoaponeurotic fibrosarcoma oncogene homolog K (MAFK) in osteosarcoma cell proliferation in vitro and the possible pathways that contributed to MAFK-related osteosarcoma development. A significant correlation between MAFK and the Wnt signaling pathway was observed with Wnt1-induced MAFK expression causing a significant increase in cell viability, while Wnt pathway inhibitor, IWR-1-endo, abolished Wnt1-induced effects on MAFK. -SCBT Publication Review
