Research Abstract |
We examined osteocyte response to mechanical stress focusing on CTGF and apoptosis. Compressive force loading increased CTGF expression, thereafter, apoptosis were induced in osteocytes. Moreover, we demonstrated that CTGF induces osteocyte apoptosis through activation of ERK1/2 pathway. These results, at least in part, revealed the mechanism of bone remodeling regulated by osteocytes under mechanical stress.
