Research Abstract

The purpose of this study is clarifying a role of atypical Wnt receptor Ryk in the bone metabolism. Ryk was called a heretical Wnt receptor because of its function and properties in both canonical and non-canonical Wnt pathway. Ryk binds to Wnt3a (a canonical ligand) and Wnt5a (a non-canonical ligand), and transduces signals to control many biological processes. Ryk is expressed in both osteoclast-lineage cells and osteoblasts. Wegenerated conditional Ryk knockout mice to delete Ryk gene in these cells.
