Outline of Final Research Achievements

This study aimed to elucidate the functional role of mitochondrial Rho GTPase 1 (RhoT1), mitochondrial transporter factor, on the repair of periodontal tissue. RhoT1 expressed on mesenchymal stromal cells (MSCs) in periodontal ligament (PDL) and the level of its expression increased with stimulation of LPS and starvation state. In addition, damaged PDL MSCs were rescued by a transport of mitochondria from intact PDL MSCs and then were survived. These finding indicated that RhoT1 is important for restoring the damage of periodontal ligament cells.
