项目摘要

The goal of this project is to define the molecular mechanisms governing neural tube closure. Neural tube defects (NTDs) are amongst the most common human structural congenital malformations. In this project, we focus on a highly expressed microRNA family in pluripotency, miR-302, which plays a critical role during neural tube closure. Using genetic loss-of-function mouse, chicken and human models, we find that miR-302 is required to prevent precocious differentiation of the neuroepithelium. Additionally, we present data suggesting that miR- 302 is mutated in humans with neural tube closure defects. This project will provide insight into the earliest stages of neural tube development and inform our understanding of how microRNAs control this critical process.

该项目的目标是定义控制神经管闭合的分子机制。神经管缺陷（NTD）是最常见的人类结构性先天畸形之一。在这个项目中，我们重点关注多能性高表达的 microRNA 家族 miR-302，它在神经管闭合过程中发挥着关键作用。使用遗传功能丧失的小鼠、鸡和人类模型，我们发现 miR-302 是防止神经上皮过早分化所必需的。此外，我们提供的数据表明 miR-302 在患有神经管闭合缺陷的人类中发生突变。该项目将深入了解神经管发育的最早阶段，并让我们了解 microRNA 如何控制这一关键过程。
