| Outline of Final Research Achievements |
In the rat sciatic nerve transection model, not only the Wnt/beta-catenin pathway but also the non-canonical pathway of Wnt signaling, such as Wnt4, Wnt9a, Wnt11, were activated secondary to traumatic nerve injury. The effect of the Wnt antagonists on acetylcholine receptor (AChR) cluster formation were also investigated. The treatment of C2C12 myotubes by IWR1 and porc inhibitor increased the number of AChR clusters. Wnt signaling pathway may be a useful therapeutic target to prevent the motor endplate degeneration that occurs following traumatic nerve injury with Wnt inhibitors serving as a pharmacologic adjunct to surgical repair.
