项目摘要
Scientists refer to cells as being 'programmed' to divide, to die or to differentiate. This describes the elaborate, and seemingly automatic, changes that take place in the way that a cell behaves under different circumstances. For example, cells grow when provided with the right nutrients, die if irrevocably damage, or differentiate into distinctly different types of cells when in the appropriate niche environment. Cells are sensitive to the signals that dictate changes to their programmes and thus to their behaviour at a particular time in their growth cycles. Often, to execute one programme means that others are disabled. These time-sensitive switches allow coordinated and absolute decisiveness to cells' fate. These switches are comprised of a family of proteins called SCF ligases, which directly control the cell's growth machinery. Understanding the how cells make their decisions and regulate cell fate is a matter of fundamental interest, and this proposal outlines experiments designed to understand the activity of SCF proteins, and how they achieve this. In particular we will focus on a component of this SCF called Fbxo7. It differentially regulates at least three different proteins that affect cellular proliferation, death, and differentiation. In other words, it is a master regulator. We want to understand how Fbxo7 is capable of varying its activity towards the proteins it binds, and ultimately how it controls cell fate. We will use a variety of methods to understand the protein's function, to solve its structure, and find other proteins that it regulates. By doing experiments to broaden our understanding of the proteins at the intersection of different cell programmes we hope to be able to affect and ultimately direct these programmes in clinically relevant settings.
科学家将细胞称为“编程”以分裂,死亡或区分。这描述了细胞在不同情况下的行为方式发生的精致且看似自动的变化。例如,在提供合适的养分时,细胞生长,如果不可撤销的损害死亡,或者在适当的小众环境中分化为明显不同的细胞。细胞对决定其程序的变化,从而在其生长周期中的特定时间敏感,从而决定其程序的变化。通常,执行一个程序意味着其他程序被禁用。这些时间敏感的开关允许对细胞的命运进行协调和绝对的决定性。这些开关由一种称为SCF连接酶的蛋白质组成,该蛋白质直接控制了细胞的生长机制。了解细胞如何做出决策并调节细胞命运是一个基本兴趣的问题,该提案概述了旨在了解SCF蛋白活性以及如何实现这一目标的实验。特别是,我们将重点关注该SCF的组件,称为FBXO7。它差异调节了影响细胞增殖,死亡和分化的三种不同的蛋白质。换句话说,它是主调节器。我们想了解FBXO7如何能够改变其对蛋白质结合的蛋白质的活性,并最终如何控制细胞命运。我们将使用多种方法来了解蛋白质的功能,解决其结构,并找到其调节的其他蛋白质。通过进行实验,以扩大我们对不同细胞程序的交集的蛋白质的理解,我们希望能够影响并最终将这些程序引导在临床相关的环境中。
