众多细胞类型的多细胞生物体必须单独微调其内部代谢。一个重要的代谢和应激调节机制是葡萄糖衍生的糖N-乙酰氨基葡萄糖在蛋白质上的动态附着/移除(O-GlcN酰化)。O-GlcNAc修饰的蛋白质数量令人困惑,在人类细胞中有7000+位点。悬而未决的挑战是确定关键的O-GlcNAc位点如何在数千个潜在的全球位点中调节靶途径。在细胞模型和疾病治疗方面,需要创新的解决方案来应对这一挑战。这一观点分享了从国际O-GlcNAc社区收集的关于O-GlcNAc领域的关键建议。此外,我们总结了关键的工具和策略,使O-GlcNAc生物学的新手能够在新陈代谢和疾病的界面上推动创新。O-GlcNAc研究的步伐越来越快,这使得现在是一个及时的节点,让广泛的科学家和新的工具制造商有选择地探讨O-GlcNAc在疾病中的调节作用。
The vast array of cell types of multicellular organisms must individually fine-tune their internal metabolism. One important metabolic and stress regulatory mechanism is the dynamic attachment/removal of glucose-derived sugar N-acetylglucosamine on proteins (O-GlcNAcylation). The number of proteins modified by O-GlcNAc is bewildering, with 7000+ sites in human cells. The outstanding challenge is determining how key O-GlcNAc sites regulate a target pathway amidst thousands of potential global sites. Innovative solutions are required to address this challenge in cell models and disease therapy. This Perspective shares critical suggestions for the O-GlcNAc field gleaned from the international O-GlcNAc community. Further, we summarize critical tools and tactics to enable newcomers to O-GlcNAc biology to drive innovation at the interface of metabolism and disease. The growing pace of O-GlcNAc research makes this a timely juncture to involve a wide array of scientists and new tool makers to selectively approach regulatory roles of O-GlcNAc in disease.
