| Outline of Final Research Achievements |
Osteoblasts/stromal cells secrete osteoprotegerin (OPG), which is a soluble member of the TNF receptor superfamily. OPG acts as a decoy receptor for RANKL, thereby preventing its interaction with the cognate receptor RANK. OPG is known to be expressed not only in bone tissue but also in many other tissue types, including myocardium. Recently, OPG has been reported to be associated with various cardiac diseases. The present study analyzed the serum OPG concentration in forensic autopsy cases (including those of cardiac sudden death). In particular, the expression of OPG and its receptor RANK were evaluated by immunohistochemistry of the myocardium. The results of this study will be presented in the 100th Congress of the Japanese Society of Legal Medicine (Tokyo, 2016). In addition, a collaborative study regarding mouse OPG gene expression and the sFRP gene has been published in PLOS ONE (Mori et al. 2014).
