The PhD project will use state-of-the-art single-molecule fluorescence techniques to study the structure, dynamics and interactions of DNA secondary structures containing short tandem repeats. These structures are implicated in the cause of almost 50 neurodegenerative diseases. Recent work from the Magennis lab showed that DNA structures formed from CAG or CTG triplet repeats undergo unexpected structural rearrangements [Nat. Commun., 2021 12, 204]. We now wish to understand whether this unusual dynamic behaviour is important for cellular processing, and to investigate the potential for these structures to act as drug targets.

该博士项目将使用最先进的单分子荧光技术来研究含有短串联重复序列的 DNA 二级结构的结构、动力学和相互作用。这些结构与近 50 种神经退行性疾病的病因有关。 Magennis 实验室最近的工作表明，由 CAG 或 CTG 三联体重复形成的 DNA 结构会发生意想不到的结构重排 [Nat.通讯，2021 12, 204]。我们现在希望了解这种不寻常的动态行为对于细胞处理是否重要，并研究这些结构作为药物靶点的潜力。
