Notch受体控制组织形态发生过程,涉及细胞结构和基因表达的协调变化,但单个受体如何产生这些不同的生物输出尚不清楚。在这里,我们采用了一个三维模型的人导管上皮细胞,以揭示组织形态缺陷的损失造成的Notch 1,但不是Notch 1转录信号。相反,导管形态发生的缺陷是由失调的上皮细胞结构和促有丝分裂信号传导驱动的,这是由转录独立的Notch 1皮质信号传导机制的丧失引起的,该机制最终起到稳定粘附连接和皮质肌动蛋白的作用。我们发现Notch 1定位和皮质信号与顶-基底细胞重组有关,并发现Notch 1-FAM 83 H相互作用是控制上皮粘附连接和皮质肌动蛋白的基础。总之,这些结果提供了新的见解Notch 1信号和调节,并推进了一个范例,其中转录和细胞粘附程序可能是由一个单一的受体协调。
Notch receptors control tissue morphogenic processes that involve coordinated changes in cell architecture and gene expression, but how a single receptor can produce these diverse biological outputs is unclear. Here, we employ a 3D model of a human ductal epithelium to reveal tissue morphogenic defects result from loss of Notch1, but not Notch1 transcriptional signaling. Instead, defects in duct morphogenesis are driven by dysregulated epithelial cell architecture and mitogenic signaling which result from the loss of a transcription-independent, Notch1 cortical signaling mechanism that ultimately functions to stabilize adherens junctions and cortical actin. We identify that Notch1 localization and cortical signaling are tied to apical–basal cell restructuring and discover that a Notch1–FAM83H interaction underlies control of epithelial adherens junctions and cortical actin. Together, these results offer new insights into Notch1 signaling and regulation and advance a paradigm in which transcriptional and cell adhesive programs might be coordinated by a single receptor.
