YAP/TAZ 是哺乳动物 Hippo 信号传导的主要介质;然而,它们在胃肠道中的确切功能仍然知之甚少。在这里,我们剖析了 YAP/TAZ 在内胚层上皮和间充质中的独特作用,发现虽然 YAP/TAZ 对于胃肠道上皮发育和稳态是可有可无的,但 YAP/TAZ 充当协调肠道间充质生长和模式的关键分子开关。我们的遗传分析表明,Lats1/2 激酶抑制原始间充质祖细胞的扩张,其中 YAP 激活还可以通过心肌素的转录抑制来阻止平滑肌谱系的诱导。在后期发育过程中,YAP/TAZ 的区域限制性下调提供了位置提示,并允许 Hedgehog 信号传导诱导平滑肌细胞分化。综上所述,我们的研究确定了胃肠道中 YAP/TAZ 的间充质需求,并强调了 Hippo 和 Hedgehog 信号之间的功能相互作用,这些信号是肠道发育中组织生长和规范的时间和空间控制的基础。 Hippo 效应器 YAP/TAZ 在胃肠道中的精确功能仍然难以捉摸。科顿等人。确定了 YAP/TAZ 在协调肠道间质生长和模式形成中的关键作用,并强调了 Hippo 和 Hedgehog 信号之间在平滑肌规范时空控制下的功能相互作用。
YAP/TAZ are the major mediators of mammalian Hippo signaling; however, their precise function in the gastrointestinal tract remains poorly understood. Here we dissect the distinct roles of YAP/TAZ in endodermal epithelium and mesenchyme, and find that, although dispensable for gastrointestinal epithelial development and homeostasis, YAP/TAZ function as the critical molecular switch to coordinate growth and patterning in gut mesenchyme. Our genetic analyses reveal that Lats1/2 kinases suppress expansion of the primitive mesenchymal progenitors, where YAP activation also prevents induction of the smooth muscle lineage through transcriptional repression of Myocardin. During later development, zone-restricted down-regulation of YAP/TAZ provides the positional cue and allows smooth muscle cell differentiation induced by Hedgehog signaling. Taken together, our studies identify the mesenchymal requirement of YAP/TAZ in the gastrointestinal tract, and highlight the functional interplays between Hippo and Hedgehog signaling underlying temporal and spatial control of tissue growth and specification in developing gut. The precise function of the Hippo effectors, YAP/TAZ, in the gastrointestinal tract remains elusive. Cotton et al. identify a key role of YAP/TAZ in coordination of growth and patterning in gut mesenchyme, and highlight the functional interplay between Hippo and Hedgehog signaling underlying the spatial-temporal control of smooth muscle specification.
