摘要
骨代谢的平衡取决于骨形成及骨吸收之间的动态平衡,Wnt/β-catenin信号通路能够广泛参与骨吸收及骨形成的调控,在维持骨代谢平衡中发挥着重要作用。近年来有研究表明,长链非编码RNA (Long non-coding RNA,lncRNA)也广泛参与骨代谢各阶段的调节,还能通过Wnt/β-catenin信号通路参与骨代谢平衡的调控。目前关于lncRNA介导Wnt/β-catenin信号通路调控骨代谢的综述报道较为鲜见。鉴于此,文中主要以Wnt/β-catenin信号通路为切入点,概述lncRNA在骨代谢中的调控作用,发现lncRNA能够通过靶向作用于miRNA间接调控Wnt/β-catenin信号通路,也能通过Wnt/β-catenin信号通路上的关键因子直接激活或抑制Wnt/β-catenin信号通路,进而发挥其对骨代谢的调控作用,这些发现为lncRNA调控骨代谢作用机制的研究提供了新的思路和方向。
The balance of bone metabolism depends on the dynamic balance between bone formation and bone resorption. Wnt/β-catenin signaling pathway is involved in the regulation of bone resorption and bone formation, and plays an important role in maintaining the balance of bone metabolism. Recently, long non-coding RNA(lncRNA) is shown to play an essential role in different process of bone metabolism. LncRNA can also regulate the balance of bone metabolism via Wnt/β-catenin signaling pathway. Few studies report that lncRNA regulates bone metabolism via Wnt/β-catenin signaling pathway. Therefore, we summarize here the role of lncRNA in bone metabolism from the perspective of Wnt/β-catenin signaling pathway. LncRNA indirectly regulates Wnt/β-catenin signaling pathway by targeting miRNAs as well as activating or inhibiting Wnt/β-catenin signaling pathway via targeting the key molecules of Wnt/β-catenin signaling pathway, thus to regulate bone metabolism. These findings provide new ideas and directions for the study of the mechanism whereby lncRNA regulates bone metabolism.
