Outline of Final Research Achievements

Mechanical stimuli induce osteocyte apoptosis, followed by bone resorption. A neural factor, methionine enkephalin (MENK), is involved in bone metabolism and apoptosis. In this study, we clarified the role of MENK in the osteocyte apoptosis promoted by mechanical stimuli. Our data showed that MENK expression was reduced by compressive force loading on the parietal bones, and that this reduction in MENK expression was regulated by CCN2/CTGF. In addition, the apoptosis of osteocytes induced by compressive force was suppressed by MENK through the regulation of calcium signaling and NFATc1 nuclear translocation.

Academic Significance and Societal Importance of the Research Achievements

近年、神経性因子の骨代謝制御が注目されるが、骨細胞により産生される神経性因子の機能の多くは不明である。我々が世界で初めて示した、MENKによる骨細胞のアポトーシス制御機構は、骨細胞と神経性因子に着目した骨代謝機序研究の新展開につながる。また、機械的刺激に応答する骨代謝や骨細胞アポトーシスにおけるMENKを基軸とした制御機序の解明により、これらの骨の異常を防ぐ新たな治療法開発につながる基盤的知見となることが期待される。
