O连接N-乙酰葡萄糖胺糖基化修饰在神经退行性疾病中的研究进展 [PDF]
O连接N-乙酰葡萄糖胺（O-GlcNAc）糖基化是一种由O-键连接的乙酰氨基葡萄糖和胞内蛋白上的丝氨酸/苏氨酸残基形成的蛋白质翻译后修饰。O-GlcNAc糖基化修饰在脑内普遍存在，其与转录、翻译和蛋白稳态等关系密切。O-GlcNAc糖基化修饰参与多种神经系统变性疾病的发生发展，但其调控机制尚不清楚。现就O ...

Characterization of Tmem59l knockout mice [PDF]
, 2015 TMEM59L是一种脑特异性高表达蛋白，其组织表达的特异性预示着TMEM59L可能在神经系统发育和神经退行性疾病发生中起着重要的作用，但是目前对于该蛋白的生理学和病理学功能都知之甚少，有必要在动物水平上加以深入研究。 我们最近获得了Tmem59l基因敲除小鼠。在本论文中，我们对该小鼠的表型进行了系统分析。我们发现Tmem59l-/-小鼠的出生遵从孟德尔遗传定律（+/+:+/-:-/-=72:136:65）。不过虽然Tmem59l-/-小鼠的形态大小以及脑的解剖结构与野生型小鼠没有显著差异 ...
