血管钙化抑制因子BMP-7的研究进展

Research progresses of endogenous vascular calcification inhibitor BMP-7

血管钙化是一个主动可调控的心血管系统异位钙化过程,目前尚无可逆转的有效干预手段。血管钙化和骨形成具有共同的调控机制,骨形态发生蛋白7(bone morphogenetic protein 7,BMP-7)可维持血管平滑肌细胞的收缩表型抑制血管钙化。同时,BMP-7可刺激成骨细胞分化过程,增加骨形成,减少骨吸收降低异位钙化压力。该文系统综述BMP-7影响血管钙化的作用与机制及其目前的临床应用现状。这将有助于以BMP-7为新的分子标志物与潜在药物靶标,研发早期诊断试剂盒及治疗药物,以期实现血管钙化的早期预防与干预,改善患者预后。

Vascular calcification is a highly regulated process of ectopic calcification in cardiovascular system while no effective intervention can be clinically performed up to date.As vascular calcification undergoes a common regulatory mechanism within bone formation,bone morphogenetic protein 7(BMP-7)maintains contractile phenotype of vascular smooth muscle cells and further inhibits vascular calcification via promoting the process of osteoblast differentiation,reducing ectopic calcification pressure by increasing bone formation and reducing bone resorption.This work systematically reviews the role of BMP-7 in vascular calcification and the possible mechanism,and their current clinical application as well.The current proceedings may help develope early diagnostic strategy and therapeutic treatment with BMP-7 as a new molecular marker and potential drug target.The expectation could achieve early prevention and intervention of vascular calcification and improve poor prognosis on patients.
