中文摘要
项目摘要/摘要:
我们的目标是更好地理解协调我们与复杂模式之间的关系的各种分子机制和细胞机制。
上皮性器官。这些保守的器官机制必须得到正确的调控,才能产生更多的功能器官。
在成熟的器官中经常被重新利用,以维持机体的动态平衡和功能。我们应该把重点放在保存的器官上。
核心核糖体蛋白家族成员是细胞和组织稳定性的关键调控因子:Cindr(在果蝇体内)。
小鼠的直系物包括Cin85和CD2AP。Cindr招募了包括肌动蛋白、监管机构和信号转导在内的蛋白质复合体。
蛋白质。在探索这些蛋白质复合体的动态功能以及它们是如何被调控的基础上,我们将无法阐明这一点。
分子生物学事件的系统研究表明,这些组织的模式是什么,以及它们是如何出错的。我们在初步的分子生物学研究中观察到了这一点。
Cindr基因与果蝇之间的功能相互作用;JNK基因与JNK基因之间的功能相互作用;
口罩(河马信号的一个重要组成部分)表明,它们对于正确的组织图案是必不可少的。我们的数据支持这项研究。
假设Cindr与JNK/BSK互动,以限制JNK(特定目标为1),并与MASK合作,以进一步促进其业务。
当河马发出信号时,它就会被抑制。这些都是。
初步调查结果将产生深远的影响,首先是因为JNK和河马的共同贡献。
至于器官的形态发生如何,目前还不清楚。第二,Cindr在调节信号和整合这些信号方面的主要作用。
在器官构型过程中,还没有完全探索过。为了更好地解决这些悬而未决的问题,我们将继续结合遗传学,。
生物化学、免疫荧光技术和活细胞成像技术等方法有助于阐明这些细胞的具体贡献。

英文摘要
PROJECT SUMMARY/ABSTRACT
Our goal is to understand the molecular and cellular mechanisms that coordinate to pattern complex
epithelial organs. These conserved mechanisms must be correctly regulated to generate functional organs and
are frequently re-utilized in mature organs to maintain homeostasis and function. We focus on a conserved
family of core adaptor proteins that are key regulators of cell and tissue stability: Cindr (in Drosophila) and the
mouse orthologs Cin85 and Cd2ap. Cindr recruits protein complexes that include actin regulators and signaling
proteins. Exploring the dynamic function of these complexes – and how they are regulated - will elucidate the
system of molecular events that pattern tissues and how these go awry. In preliminary studies we observed
functional interactions between Cindr and the Drosophila Jun terminal kinase JNK (Bsk in flies) and Cindr and
Mask (a component of Hippo signaling) that are essential for correct tissue patterning. Our data supports the
hypotheses that Cindr interacts with JNK/Bsk to restrict JNK (Specific Aim 1) and with Mask to promote its
function and that of its cofactor Yki (Specific Aim 2) which is repressed when Hippo signaling is active. These
preliminary findings have far-reaching implications firstly because the contributions of JNK and Hippo signaling
to organ morphogenesis are unclear. Second, the role of Cindr in regulating and integrating these signals
during organ patterning has not been explored. To address these open questions, we will combine genetic,
biochemical, immunofluorescence and live-cell-imaging approaches to elucidate the specific contributions of
JNK and Mask and their interactions with Cindr to Drosophila eye patterning.
