| Research Abstract |
Wnt-β-catenin signaling is a major pathway promoting osteoblastic differentiation. However, the exact mechanisms and molecular details regulating Wnt signaling still remain to be elucidated. We found that PDZRN3 is a novel regulator of Wnt-β-catenin signaling in the differentiation of C2C12 mouse mesenchymal progenitor cells into osteoblasts. PDZRN3 suppressed the protein level of LRP6, Wnt receptor, in which PDZRN3 binds to the activated(phosphorylated) LRP6. We proposed that PDZRN3 plays an important role in negative feedback control of BMP-2-induced osteoblast differentiation in C2C12 cells through inhibition of Wnt?-catenin signaling.
