| Outline of Final Research Achievements |
Steroids are effective drugs for inflammatory diseases and autoimmune diseases. However, steroids most frequently induce secondary osteoporosis. The risk of bone fracture in the patients with steroid treatment is about 30-50%. Trabecular bone is reduced and the fractures of vertebral body and femoral neck occur in the patients with steroid treatment. Fkbp5 is a shaperon molecule of glucocorticoid receptor, and Fkbp5 knockout mice showed severely reduced bone formation by glucocorticoid treatment. We tried to identify the target genes of glucocorticoid receptor, which are responsible for steroid-induced osteoporosis, using Fkbp5 knockout mice.
