Li J, Li Z, Duan X, Qin K, Dang L, Sun S, Cai L, Hsieh-Wilson LC, Wu L, Yi W. An Isotope-Coded Photocleavable Probe for Quantitative Profiling of Protein O-GlcNAcylation. ACS chemical biology 2019 14(1) 30620550
Abstract:
O-linked N-acetylglucosamine ( O-GlcNAc) is a ubiquitous post-translational modification of proteins and is essential for cell function. Quantifying the dynamics of O-GlcNAcylation in a proteome-wide level is critical for uncovering cellular mechanisms and functional roles of O-GlcNAcylation in cells. Here, we develop an isotope-coded photocleavable probe for profiling protein O-GlcNAcylation dynamics using quantitative mass spectrometry-based proteomics. This probe enables selective tagging and isotopic labeling of O-GlcNAcylated proteins in one step from complex cellular mixtures. We demonstrate the application of the probe to quantitatively profile O-GlcNAcylation sites in 293T cells upon chemical induction of O-GlcNAc levels. We further applied the probe to quantitatively analyze the stoichiometry of O-GlcNAcylation between sorafenib-sensitive and sorafenib-resistant liver cancer cells, which lays the foundation for mechanistic investigation of O-GlcNAcylation in regulating cancer chemoresistance. Thus, this probe provides a powerful tool to profile O-GlcNAcylation dynamics in cells.

Hao Y, Fan X, Shi Y, Zhang C, Sun DE, Qin K, Qin W, Zhou W, Chen X. Next-generation unnatural monosaccharides reveal that ESRRB O-GlcNAcylation regulates pluripotency of mouse embryonic stem cells. Nature communications 2019 10(1) 31492838
Abstract:
Unnatural monosaccharides such as azidosugars that can be metabolically incorporated into cellular glycans are currently used as a major tool for glycan imaging and glycoproteomic profiling. As a common practice to enhance membrane permeability and cellular uptake, the unnatural sugars are per-O-acetylated, which, however, can induce a long-overlooked side reaction, non-enzymatic S-glycosylation. Herein, we develop 1,3-di-esterified N-azidoacetylgalactosamine (GalNAz) as next-generation chemical reporters for metabolic glycan labeling. Both 1,3-di-O-acetylated GalNAz (1,3-Ac2GalNAz) and 1,3-di-O-propionylated GalNAz (1,3-Pr2GalNAz) exhibit high efficiency for labeling protein O-GlcNAcylation with no artificial S-glycosylation. Applying 1,3-Pr2GalNAz in mouse embryonic stem cells (mESCs), we identify ESRRB, a critical transcription factor for pluripotency, as an O-GlcNAcylated protein. We show that ESRRB O-GlcNAcylation is important for mESC self-renewal and pluripotency. Mechanistically, ESRRB is O-GlcNAcylated by O-GlcNAc transferase at serine 25, which stabilizes ESRRB, promotes its transcription activity and facilitates its interactions with two master pluripotency regulators, OCT4 and NANOG.

Qin K, Zhu Y, Qin W, Gao J, Shao X, Wang YL, Zhou W, Wang C, Chen X. Quantitative Profiling of Protein O-GlcNAcylation Sites by an Isotope-Tagged Cleavable Linker. ACS chemical biology 2018 13(8) 30059200
Abstract:
Large-scale quantification of protein O-linked β- N-acetylglucosamine (O-GlcNAc) modification in a site-specific manner remains a key challenge in studying O-GlcNAc biology. Herein, we developed an isotope-tagged cleavable linker (isoTCL) strategy, which enabled isotopic labeling of O-GlcNAc through bioorthogonal conjugation of affinity tags. We demonstrated the application of the isoTCL in mapping and quantification of O-GlcNAcylation sites in HeLa cells. Furthermore, we investigated the O-GlcNAcylation sensitivity to the sugar donor by quantifying the levels of modification under different concentrations of the O-GlcNAc labeling probe in a site-specific manner. In addition, we applied isoTCL to compare the O-GlcNAcylation stoichiometry levels of more than 100 modification sites between placenta samples from male and female mice and confirmed site-specifically that female placenta has a higher O-GlcNAcylation than its male counterpart. The isoTCL platform provides a powerful tool for quantitative profiling of O-GlcNAc modification.

Artificial Cysteine S-Glycosylation Induced by Per-O-Acetylated Unnatural Monosaccharides during Metabolic Glycan Labeling. Angewandte Chemie (International ed. in English) 2018 57(7) 29237092
Abstract:
The unexpected, non-enzymatic S-glycosylation of cysteine residues in various proteins by per-O-acetylated monosaccharides is described. This artificial S-glycosylation greatly compromises the specificity and validity of metabolic glycan labeling in living cells by per-O-acetylated azido and alkynyl sugars, which has been overlooked in the field for decades. It is demonstrated that the use of unacetylated unnatural sugars can avoid the artifact formation and a corrected list of O-GlcNAcylated proteins and O-GlcNAc sites in HeLa cells has been assembled by using N-azidoacetylgalactosamine (GalNAz).

Qin W, Lv P, Fan X, Quan B, Zhu Y, Qin K, Chen Y, Wang C, Chen X. Quantitative time-resolved chemoproteomics reveals that stable O-GlcNAc regulates box C/D snoRNP biogenesis. Proceedings of the National Academy of Sciences of the United States of America 2017 114(33) 28760965
Abstract:
O-linked GlcNAcylation (O-GlcNAcylation), a ubiquitous posttranslational modification on intracellular proteins, is dynamically regulated in cells. To analyze the turnover dynamics of O-GlcNAcylated proteins, we developed a quantitative time-resolved O-linked GlcNAc proteomics (qTOP) strategy based on metabolic pulse-chase labeling with an O-GlcNAc chemical reporter and stable isotope labeling with amino acids in cell culture (SILAC). Applying qTOP, we quantified the turnover rates of 533 O-GlcNAcylated proteins in NIH 3T3 cells and discovered that about 14% exhibited minimal removal of O-GlcNAc or degradation of protein backbones. The stability of those hyperstable O-GlcNAcylated proteins was more sensitive to O-GlcNAcylation inhibition compared with the more dynamic populations. Among the hyperstable population were three core proteins of box C/D small nucleolar ribonucleoprotein complexes (snoRNPs): fibrillarin (FBL), nucleolar protein 5A (NOP56), and nucleolar protein 5 (NOP58). We showed that O-GlcNAcylation stabilized these proteins and was essential for snoRNP assembly. Blocking O-GlcNAcylation on FBL altered the 2'-O-methylation of rRNAs and impaired cancer cell proliferation and tumor formation in vivo.
