作为人体中最坚硬的组织,牙釉质的形成是一个受到高度调控的过程,涉及多个分化阶段和关键调控基因。其中一个基因,色氨酸 - 天冬氨酸重复结构域72(WDR72),被发现当缺失或突变时会导致牙釉质缺陷,引发一种被称为釉质形成不全的疾病。与调节牙齿发育的经典基因不同,WDR72保留在细胞内,不会被分泌到牙釉质基质空间以调节矿化,并且在身体的其他主要器官,即肾脏、大脑、肝脏和心脏中也有发现。到目前为止,细胞内囊泡运输和牙釉质矿化之间的联系已被提出,然而其机制调控因子的确定尚未阐明,部分原因是研究高度分化的成釉细胞存在局限性。在此我们展示了令人信服的证据,表明WDR72在体内以及一种新型的体外成釉细胞系中调节蛋白质的内吞作用。我们阐明WDR72的功能与细胞内囊泡酸化无关,但仍然会导致细胞外牙釉质基质pH异常。我们确定了一种与微管组装相关的囊泡功能,并提出WDR72指导微管组装,这对于膜的动员以及随后的囊泡运输是必需的。了解WDR72的功能为确定生理和病理组织矿化提供了一个机制基础。
As the hardest tissue in the human body, tooth enamel formation is a highly regulated process involving several stages of differentiation and key regulatory genes. One such gene, tryptophan‐aspartate repeat domain 72 (WDR72), has been found to cause a tooth enamel defect when deleted or mutated, resulting in a condition called amelogenesis imperfecta. Unlike the canonical genes regulating tooth development, WDR72 remains intracellularly and is not secreted to the enamel matrix space to regulate mineralization, and is found in other major organs of the body, namely the kidney, brain, liver, and heart. To date, a link between intracellular vesicle transport and enamel mineralization has been suggested, however identification of the mechanistic regulators has yet to be elucidated, in part due to the limitations associated with studying highly differentiated ameloblast cells. Here we show compelling evidence that WDR72 regulates endocytosis of proteins, both in vivo and in a novel in vitro ameloblast cell line. We elucidate WDR72’s function to be independent of intracellular vesicle acidification while still leading to defective enamel matrix pH extracellularly. We identify a vesicle function associated with microtubule assembly and propose that WDR72 directs microtubule assembly necessary for membrane mobilization and subsequent vesicle transport. Understanding WDR72 function provides a mechanistic basis for determining physiologic and pathologic tissue mineralization.
