| Outline of Final Research Achievements |
Bone remodeling, resorption and formation in alveolar bone, occur during orthodontic tooth movement. It was suggested that osteocytes apoptosis associated with bone resorption. Compressive force applied mouse cranial sutures increased the protein expression of CCN2 and p53, and a rate of apoptosis cell. Mechanical stresses induced the expression level of CCN2, p53, apoptosis regulator Bax and Caspase-3 in osteocyte-like cell line MLO-Y4. These findings suggest that compressive force induces the expression of CCN2 and p53 in osteocyte and may enhance apoptosis through activation of caspase signal.
