| Outline of Final Research Achievements |
In addition to providing skeletal support, it was recently revealed that the bone is an endocrine organ that produces osteocalcin. Osteocalcin produced in osteoblasts plays an important role in glucose and energy metabolism. We elucidate that osteocalcin promotes the expression of adiponectin facilitating glucose and lipid metabolism and the signaling pathway by which osteocalcin induces adiponectin expression in adipocytes.
In the process, we identified that high-dose osteocalcin inversely abolished the expression of adiponectin, and revealed that high-dose osteocalcin allowed adipocytes to lead to death and a part of the signaling pathway.
