Outline of Final Research Achievements |
In this study, we investigated the genes responsible for progression of periodontal disease based on the information of molecular epidemiological studies of over 70-year-old adult, aged twins and aggressive periodontitis patients. Moreover, we analyzed the expression and function of the various candidate genes. As a result, we confirmed that genetic factor is associated with the progression of periodontal disease and found that cathepsin A might be a responsible gene for aggressive periodontitis as assessed by the epidemiological database. We also revealed that CD73, PLAP-1, ferritin, and periostin are deeply involved in the cytodifferentiation and mineralization of periodontal ligament cells which play crucial roles in periodontal tissue homeostasis.
