Abstract: BACKGROUND: The abnormal aggregation of proteins and the loss of neurons are typical pathological changes observed in neurodegenerative diseases. Changes in the levels of O-linked N-acetylglucosamine glycosylation are closely related to relevant pathological changes and are promising potential therapeutic targets.
OBJECTIVE: To review the role of O-linked N-acetylglucosamine glycosylation in neurodegenerative diseases and the current advancements in its clinical applications, aiming to provide new insights for the treatment of neurodegenerative disorders.
METHODS: The first author conducted a literature search in the CNKI, VIP, WanFang Database, ChiCTR, Web of Science, PubMed, Cochrane Library, Clinical Trials and Alzforum, using the search terms “O-GlcNAcylation, Neurodegenerative diseases, Alzheimer’s disease, Parkinson’s disease, Amyotrophic lateral sclerosis, Huntington’s disease, OGA inhibitors, Clinical trial” in Chinese and English. A total of 66 relevant articles were included for review.
RESULTS AND CONCLUSION: O-linked N-acetylglucosamine glycosylation is involved in the development and functional regulation of neurons, and its levels gradually decrease as neuronal development matures. In neurodegenerative diseases, the pathological proteins involved are regulated by O-linked N-acetylglucosamine glycosylation. Most evidence suggests that using O-GlcNAcase inhibitors to enhance O-linked N-acetylglucosamine glycosylation levels can significantly alleviate related pathological changes, making it a potential therapeutic strategy for neurodegenerative diseases. Some O-GlcNAcase inhibitors have completed Phase I clinical trials, demonstrating good safety and tolerability.
