在发育和再生过程中,组织特异性干细胞的增殖受到严格控制,以产生预定大小的器官。这一过程的分子决定因素仍然知之甚少。在这里,我们研究了 Yap1(Hippo 信号通路的转录效应子)在皮肤生物学中的功能。通过功能获得和功能丧失研究,我们表明 Yap1 是表皮干细胞增殖和组织扩张的关键调节剂。 Yap1 通过与 TEAD 转录因子相互作用来介导这种效应。此外,我们的研究表明,α-连环蛋白(一种先前与皮肤肿瘤抑制和细胞密度传感有关的分子)是 Yap1 的上游负调节因子。 α-catenin 通过调节 Yap1 与 14-3-3 和 PP2A 磷酸酶的相互作用来控制 Yap1 活性和磷酸化。总之,这些数据表明 Yap1 是表皮干细胞增殖能力的决定因素,也是哺乳动物皮肤中“群体控制”分子回路的重要效应器。
During development and regeneration, proliferation of tissue-specific stem cells is tightly controlled to produce organs of a predetermined size. The molecular determinants of this process remain poorly understood. Here, we investigate the function of Yap1, the transcriptional effector of the Hippo signaling pathway, in skin biology. Using gain- and loss-of-function studies we show that Yap1 is a critical modulator of epidermal stem cell proliferation and tissue expansion. Yap1 mediates this effect through interaction with TEAD transcription factors. Additionally, our studies reveal that α-catenin, a molecule previously implicated in tumor suppression and cell density sensing in the skin, is an upstream negative regulator of Yap1. α-catenin controls Yap1 activity and phosphorylation by modulating its interaction with 14-3-3 and the PP2A phosphatase. Together, these data identify Yap1 as a determinant of the proliferative capacity of epidermal stem cells and as an important effector of a ‘crowd control’ molecular circuitry in mammalian skin.
