Abstract:
O-linked β-N-acetylglucosamine (O-GlcNAc) is a reversible post translational modification (PTM) involving the attachment of β-N-acetylglucosamine to serine or threonine residues of target proteins. This modification regulates a wide range of cellular functions, including signal transduction, gene expression, protein stability, and cellular metabolism. However, the regulatory patterns of O-GlcNAc in cell death have not been thoroughly summarized or extensively discussed, and detailed mechanistic studies remain limited. This review provides an updated overview of recent advances linking O-GlcNAc with principal types of programmed cell death (PCD), including apoptosis, autophagy, pyroptosis, ferroptosis, and necroptosis. The occurrence of these forms of PCD plays a critical role in exacerbating immune-inflammatory diseases, neurodegenerative disorders, organ and tissue injury, cardiovascular diseases, and metabolic diseases, whereas in cancer, the induction of PCD can inhibit tumor initiation and progression. Therefore, we focus on the emerging roles of O-GlcNAc in modulating principal types of PCD in these diseases and discuss its potential as a therapeutic target.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
