摘要: 摘要:  骨密度是用于诊断骨质疏松症和评价骨折风险的重要临床指标,受多种遗传及环境因素共同影响。近年的研究显示,低密度脂蛋白受体相关蛋白5(Low-density lipoprotein receptor-related protein 5,LRP5),与成骨细胞分化及功能关系密切,与骨密度和/或骨质疏松性骨折呈相关性。本文对LRP5编码基因的定位及表达、LRP5蛋白结构与功能、LRP5与骨密度及骨折的相关关系进行综述,以探讨LRP5与骨量相关的可能机制。

Abstract: Abstract:Bone mineral density(BMD), as an clinical marker for diagnosis of osteoporosis and assessment of fracture risk, is likely affected by multiple genetic and environmental factors. Recently, researches suggest that low-density lipoprotein receptor-related protein 5(LRP5) is closely related to bone mass and differentiation of osteoblasts. Furthermore, LRP5 is also associated to BMD and/or osteoporotic fracture. We review LRP5 gene locus, expression,structure,function and association between LRP5 and bone mass, in order to investigate the likely mechanisms of the association.

Key words: Low-density lipoprotein receptor-related protein 5(LRP5), Bone mass, Osteoblast
