【 摘 要 】

References(33)Cited-By(3)Rho-kinase (ROK), downstream of the mevalonate pathway, is detrimental to vessels, and suppressing its activity is a target for the treatment of human disease such as coronary artery disease and pulmonary hypertension. Recent studies have shown that ROK has a crucial role in bone metabolism. However, the role of ROK in stromal cells is still unclear. The present study was undertaken to investigate the effect of a ROK inhibitor, fasudil hydrochloride, on stromal cell lines, C3H10T1/2 and ST2. In both cells, Fasudil significantly stimulated alkaline phosphatase activity and enhanced cell mineralization. Moreover, fasudil significantly increased the mRNA expression of collagen-I, osteocalcin, and bone morphogenetic protein-2 (BMP-2). Supplementation of noggin, a BMP-2 antagonist, significantly reversed the fasudil-induced collagen-I and osteocalcin mRNA expression in both cells. These findings suggest that fasudil induces the osteoblastic differentiation of stromal cells via enhancing BMP-2 expression, and that this drug might be beneficial for not only atherosclerosis but also osteoporosis by promoting bone formation.
