| Outline of Final Research Achievements |
Amelogenin, the major component of enamel matrix derivative (Straumann® Emdogain), is well recognized in periodontology. It is used in periodontal surgery to regenerate cementum, periodontal ligament, and alveolar bone. However, the precise molecular mechanisms underlying periodontal regeneration are still unclear.In order to gain further insight into how amelogenin induces periodontal tissue regeneration, we conducted a protein interaction screen using recombinant full-length amelogenin (rM180) as bait. Using this proteomic screen we identified glucose-regulated protein 78 (Grp78) as an amelogenin-binding protein.our study demonstrates that the biological interaction of Grp78 with amelogenin enhances amelogenin-induced cell migration in PDLSCs. Our findings provide a better understanding of the molecular basis of amelogenin-induced periodontal regeneration.
