Abstract

Dysfunction of primary cilia leads to genetic disorder, ciliopathies, which shows various malformations in many vital organs such as brain. Multiple tongue deformities including cleft, hamartoma, and ankyloglossia are also seen in ciliopathies, which yield difficulties in fundamental functions such as mastication and vocalization. Here, we found these tongue anomalies in mice with mutation of ciliary protein. Abnormal cranial neural crest-derived cells (CNCC) failed to evoke Hh signal for differentiation of mesoderm-derived cells into myoblasts, which resulted in abnormal differentiation of mesoderm-derived cells into adipocytes. The ectopic adipose subsequently arrested tongue swelling formation. Ankyloglossia was caused by aberrant cell migration due to lack of non-canonical Wnt signaling. In addition to ciliopathies, these tongue anomalies are often observed as non-familial condition in human. We found that these tongue deformities could be reproduced in wild-type mice by simple mechanical manipulations to disturb cellular processes which were disrupted in mutant mice. Our results provide hints for possible future treatment in ciliopathies.

摘要

原发性纤毛功能障碍导致遗传疾病——纤毛病,其在大脑等许多重要器官表现出多种畸形。纤毛病还会出现多种舌畸形,包括裂舌、错构瘤和舌系带过短,这些畸形会导致咀嚼和发声等基本功能出现困难。在这里,我们在纤毛蛋白突变的小鼠中发现了这些舌异常。异常的颅神经嵴衍生细胞 (CNCC) 未能引发 Hh 信号,从而导致中胚层衍生细胞向成肌细胞的分化异常,这导致中胚层衍生细胞异常分化为脂肪细胞。异位脂肪随后阻止了舌肿胀的形成。舌系带过短是由于缺乏非经典 Wnt 信号导致细胞迁移异常所致。除纤毛病外,这些舌畸形在人类中也常表现为非家族性疾病。我们发现,通过简单的机械操作扰乱细胞过程,可以在野生型小鼠中重现这些舌畸形,而这些细胞过程在突变型小鼠中被打乱。我们的研究结果为纤毛病的可能的未来治疗提供了线索。
