Outline of Final Research Achievements |
In order to establish a new strategic foundation for the control of the pathology of osteoporosis, we focused on the molecular mechanism of bone formation promotion based on the interaction with the signal of parathyroid hormone receptor (PPR) coordinated with IRISIN. First, IRISIN was expressed in hard tissues in a time series. As a result, IRISIN expression in hard tissues and its time dependence were clarified. In addition, as an epigenetic control study in hard tissues, we focused on histone methyltransferase G9a to clarify the localization of mRNA and protein. We also revealed that oxidative stress suppressed the level of Lgr4 and the interaction between PTH receptor and beta AdR.
