| Research Abstract |
We showed that inhibition of the mevalonate pathway by AICAR, Metformin, and Fasdiul is involved in osteoblast differentiation, suggesting that these drugs for diabetes mellitus and vascular diseases are also effective for enhancement in bone formation. In clinical studies, we found that bone mineral density is not useful for assessing the risk of vertebral fractures in patients with type 2 diabetes. Serum levels of pentosidine, esRAGE, and IGF-I could be surrogate markers for its assessment in replace for the insensitiveness of BMD. We also found that serum osteocalcin level, an osteoblast-specific protein, is inversely associated with diabetic and atherosclerotic indices, suggesting the existence of common pathogenesis between bone and glucose metabolism through osteocalcin action.
