Outline of Final Research Achievements |
Apert syndrome is characterized by craniosynostosis and syndactyly, and is predominantly caused by point mutation of either S252W or P253Rin the fibroblast growth factor receptor (FGFR) 2 gene. These mutation cause activation of FGFR2 depending on ligand binding. Recently, an Apert syndrome mouse model(FGFR2 knock-in mouse model) showed phenotypes similar to those of Apert syndrome patients. In this study, we plan to investigate the phenotypes of Apert syndrome mouse model to clarify the pathogenic mechanism of Apert syndrome. Moreover, we analyze the effects of FGF signal control by heparan sulfate (HS) chains degrading enzyme craniosynostosis to improve new noninvasive therapeutic approach. We planned and performed the experiment that we operated HS chain degrading enzyme on coronal suture of mouse at a fetal age by gel beads as a carrier material locally. Our results suggest that HS chain degrading enzyme could be a useful tool for treating craniosynostosys in Apert syndrome.
