J Dent Res:WNT活性对于鱼牙齿数量的时序调控

2018-12-16 lishiting MedSci原创

Wnts在胚胎发生过程中调节着细胞的极化、增殖和分化,并且在牙齿发育的起始和形态发生阶段扮演着极其重要的角色。在发育中,Wnt/β-catenin信号扮演着时间依赖的角色,因为多种信号分子相互作用涉及到此通路,并且对通路的紧密调控对于正常的发育起到非常重要的作用。然而,关于Wnt/β-catenin信号通路如何调控牙齿发育不同阶段的研究极少。特别是,Wnt/β-catenin信号失去功能对牙齿发育

Wnts在胚胎发生过程中调节着细胞的极化、增殖和分化,并且在牙齿发育的起始和形态发生阶段扮演着极其重要的角色。在发育中,Wnt/β-catenin信号扮演着时间依赖的角色,因为多种信号分子相互作用涉及到此通路,并且对通路的紧密调控对于正常的发育起到非常重要的作用。然而,关于Wnt/β-catenin信号通路如何调控牙齿发育不同阶段的研究极少。特别是,Wnt/β-catenin信号失去功能对牙齿发育的不同阶段的影响目前为止还未可知。此项研究中,作者报道了Wnt/β-catenin信号通路在牙齿发育过程中阶段依赖模式的作用。

研究通过DKK1过表达和热冲击诱导模型以及药理学抑制斑马鱼中β-catenin破坏复合体的形成分别构建Wnt/β-catenin信号在体内的功能缺失和获取。结果显示,瞬时抑制Wnt/β-catenin信号会以阶段依赖的模式干预牙齿的发育,在4V形态发生过程中条件激活Wnt/β-catenin信号会抑制V3的发育。

这些结果表明,Wnt/β-catenin信号在牙齿发生过程中扮演着重要的角色,并且以阶段依赖的模式调节连续牙齿发育过程中的起始阶段。
