Hao Y, Li X, Qin K, Shi Y, He Y, Zhang C, Cheng B, Zhang X, Hu G, Liang S, Tang Q, Chen X. Chemoproteomic and Transcriptomic Analysis Reveals that O-GlcNAc Regulates Mouse Embryonic Stem Cell Fate through the Pluripotency Network. Angewandte Chemie (International ed. in English) 2023 36852467
Abstract:
Self-renewal and differentiation of embryonic stem cells (ESCs) are influenced by protein O-linked β-N-acetylglucosamine (O-GlcNAc) modification, but the underlying mechanism remains incompletely understood. Herein, we report the identification of 979 O-GlcNAcylated proteins and 1340 modification sites in mouse ESCs (mESCs) by using a chemoproteomics method. In addition to OCT4 and SOX2, the third core pluripotency transcription factor (PTF) NANOG was found to be modified and functionally regulated by O-GlcNAc. Upon differentiation along the neuronal lineage, the O-GlcNAc stoichiometry at 123 sites of 83 proteins-several of which were PTFs-was found to decline. Transcriptomic profiling reveals 2456 differentially expressed genes responsive to OGT inhibition during differentiation, of which 901 are target genes of core PTFs. By acting on the core PTF network, suppression of O-GlcNAcylation upregulates neuron-related genes, thus contributing to mESC fate determination.

Deracinois B, Camoin L, Lambert M, Boyer JB, Dupont E, Bastide B, Cieniewski-Bernard C. O-GlcNAcylation site mapping by (azide-alkyne) click chemistry and mass spectrometry following intensive fractionation of skeletal muscle cells proteins. Journal of proteomics 2018 186 30016717
Abstract:
The O-linked-N-acetyl-d-glucosaminylation (O-GlcNAcylation) modulates numerous aspects of cellular processes. Akin to phosphorylation, O-GlcNAcylation is highly dynamic, reversible, and responds rapidly to extracellular demand. Despite the absolute necessity to determine post-translational sites to fully understand the role of O-GlcNAcylation, it remains a high challenge for the major reason that unmodified proteins are in excess comparing to the O-GlcNAcylated ones. Based on a click chemistry approach, O-GlcNAcylated proteins were labelled with azido-GalNAc and coupled to agarose beads. The proteome extracted from C2C12 myotubes was submitted to an intensive fractionation prior to azide-alkyne click chemistry. This combination of fractionation and click chemistry is a powerful methodology to map O-GlcNAc sites; indeed, 342 proteins were identified through the identification of 620 peptides containing one or more O-GlcNAc sites. We localized O-GlcNAc sites on proteins involved in signalling pathways or in protein modification, as well as structural proteins. Considering the recent role of O-GlcNAcylation in the modulation of sarcomere morphometry and interaction between key structural protein, we focused on proteins involved in the cytoarchitecture of skeletal muscle cells. In particular, several O-GlcNAc sites were located into protein-protein interaction domains, suggesting that O-GlcNAcylation could be strongly involved in the organization and reorganization of sarcomere and myofibrils.

Chuh KN, Batt AR, Zaro BW, Darabedian N, Marotta NP, Brennan CK, Amirhekmat A, Pratt MR. The New Chemical Reporter 6-Alkynyl-6-deoxy-GlcNAc Reveals O-GlcNAc Modification of the Apoptotic Caspases That Can Block the Cleavage/Activation of Caspase-8. Journal of the American Chemical Society 2017 139(23) 28528544
Abstract:
O-GlcNAc modification (O-GlcNAcylation) is required for survival in mammalian cells. Genetic and biochemical experiments have found that increased modification inhibits apoptosis in tissues and cell culture and that lowering O-GlcNAcylation induces cell death. However, the molecular mechanisms by which O-GlcNAcylation might inhibit apoptosis are still being elucidated. Here, we first synthesize a new metabolic chemical reporter, 6-Alkynyl-6-deoxy-GlcNAc (6AlkGlcNAc), for the identification of O-GlcNAc-modified proteins. Subsequent characterization of 6AlkGlcNAc shows that this probe is selectively incorporated into O-GlcNAcylated proteins over cell-surface glycoproteins. Using this probe, we discover that the apoptotic caspases are O-GlcNAcylated, which we confirmed using other techniques, raising the possibility that the modification affects their biochemistry. We then demonstrate that changes in the global levels of O-GlcNAcylation result in a converse change in the kinetics of caspase-8 activation during apoptosis. Finally, we show that caspase-8 is modified at residues that can block its cleavage/activation. Our results provide the first evidence that the caspases may be directly affected by O-GlcNAcylation as a potential antiapoptotic mechanism.
