Abstract
O-linked β-D-N-acetylglucosamine (O-GlcNAc), as a posttranslational modification (PTM), is a reversible reaction that attaches β-N-GlcNAc to Ser/Thr residues on specific proteins by O-GlcNAc transferase (OGT). O-GlcNAcase (OGA) removes the O-GlcNAc from O-GlcNAcylated proteins. O-GlcNAcylation regulates numerous cellular processes, including signal transduction, the cell cycle, metabolism, and energy homeostasis. Dysregulation of O-GlcNAcylation contributes to the development of various diseases, including cancers. Accumulating evidence has revealed that higher expression levels of OGT and hyper-O-GlcNAcylation are detected in many cancer types and governs glucose metabolism, proliferation, metastasis, invasion, angiogenesis, migration and drug resistance. In this review, we describe the biological functions and molecular mechanisms of OGT- or O-GlcNAcylation-mediated tumorigenesis. Moreover, we discuss the potential role of O-GlcNAcylation in tumor immunotherapy. Furthermore, we highlight that compounds can target O-GlcNAcylation by regulating OGT to suppress oncogenesis. Taken together, targeting protein O-GlcNAcylation might be a promising strategy for the treatment of human malignancies.

[PMID: 36104770 PMCID: PMC9476278 DOI: 10.1186/s10020-022-00544-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 09/07/2022] [Indexed: 02/07/2023] Open
Abstract
O-linked β-d-N-acetylglucosamine (O-GlcNAc) is an important post-translational modification of serine or threonine residues on thousands of proteins in the nucleus and cytoplasm of all animals and plants. In eukaryotes, only two conserved enzymes are involved in this process. O-GlcNAc transferase is responsible for adding O-GlcNAc to proteins, while O-GlcNAcase is responsible for removing it. Aberrant O-GlcNAcylation is associated with a variety of human diseases, such as diabetes, cancer, neurodegenerative diseases, and cardiovascular diseases. Numerous studies have confirmed that O-GlcNAcylation is involved in the occurrence and progression of cancers in multiple systems throughout the body. It is also involved in regulating multiple cancer hallmarks, such as metabolic reprogramming, proliferation, invasion, metastasis, and angiogenesis. In this review, we first describe the process of O-GlcNAcylation and the structure and function of O-GlcNAc cycling enzymes. In addition, we detail the occurrence of O-GlcNAc in various cancers and the role it plays. Finally, we discuss the potential of O-GlcNAc as a promising biomarker and novel therapeutic target for cancer diagnosis, treatment, and prognosis.

Spatial and temporal proteomics reveals the distinct distributions and dynamics of O-GlcNAcylated proteins. Cell Rep 2022; 39:110946. [PMID: 35705054 PMCID: PMC9244862 DOI: 10.1016/j.celrep.2022.110946] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 03/28/2022] [Accepted: 05/23/2022] [Indexed: 11/30/2022] Open
Abstract
Protein O-GlcNAcylation plays critical roles in many cellular events, and its dysregulation is related to multiple diseases. Integrating bioorthogonal chemistry and multiplexed proteomics, we systematically and site specifically study the distributions and dynamics of protein O-GlcNAcylation in the nucleus and the cytoplasm of human cells. The results demonstrate that O-GlcNAcylated proteins with different functions have distinct distribution patterns. The distributions vary site specifically, indicating that different glycoforms of the same protein may have different distributions. Moreover, we comprehensively analyze the dynamics of O-GlcNAcylated and non-modified proteins in these two compartments, respectively, and the half-lives of glycoproteins in different compartments are markedly different, with the median half-life in the cytoplasm being much longer. In addition, glycoproteins in the nucleus are more dramatically stabilized than those in the cytoplasm under the O-GlcNAcase inhibition. The comprehensive spatial and temporal analyses of protein O-GlcNAcylation provide valuable information and advance our understanding of this important modification. Xu et al. systematically and site specifically study the distribution and dynamics of O-GlcNAcylated proteins in the nucleus and the cytoplasm. O-GlcNAcylated proteins with different functions have distinct distribution patterns. The half-lives of glycoproteins in the two cellular compartments are markedly different, with the much longer median half-life in the cytoplasm.

Abstract
BACKGROUND O-linked β-N-acetylglucosamine transferase (O-GlcNAc transferase, OGT) is a key enzyme that regulates O-GlcNAc modification, which is significantly up-regulated and participates in the regulation of tumorigenesis. Although previous research indicated that OGT promotes epithelial-mesenchymal transition (EMT) of lung cancer, the underlying molecular mechanisms, especially within the tumor inflammatory microenvironment, require further elucidation. METHODS The role of the inflammatory signaling Interleukin 6/Signal Transducer and activator of transcription 3 (IL-6/STAT3) in Non-small cell lung cancer (NSCLC) cells A549 were confirmed by Transwell assay, Scratch wound healing assay, Western blot, Immunofluorescence staining, and Nuclear and cytoplasmic extraction experiment. Western blot detected OGT expression and whole protein O-GlcNacylation after IL-6 stimulation in NSCLCs cells. The biological effects and related mechanism of OGT in NSCLC cells were investigated by Western blot, Transwell assay, Immunofluorescence staining and Immunoprecipitation. The up-stream mechanism of OGT expression was explored by employing the specific chemical inhibitors, and the expression and distribution of OGT and phosphorylated STAT3 in NSCLC samples were confirmed by immunohistochemical analysis. RESULTS IL-6/STAT3 promoted the migration and invasion of NSCLC cells. IL-6 stimulation elevated OGT expression and the total protein O-GlcNacylation in A549 cells. Silencing OGT by shRNA significantly inhibited the IL-6 induced EMT marker (N-cadherin and Slug) expression, migration and invasion in A549 cells. OGT interacted with and mediated O-GlcNacylation of STAT3, which promoted STAT3 Y705 phosphorylation in IL-6 treated NSCLC cells. OGT expression was positively regulated by NF-κB p65 signaling pathway after IL-6 stimulation, instead of STAT3 signaling. OGT and phosphorylated STAT3 had an obviously higher expression in human NSCLC tissues, and phosphorylated STAT3 was mainly expressed in the nucleus. CONCLUSION The above results showed that OGT regulated O-GlcNacylation promoted migration and invasion by activating IL-6/STAT3 signaling in lung cancer.

Tumour Microenvironment: Roles of the Aryl Hydrocarbon Receptor, O-GlcNAcylation, Acetyl-CoA and Melatonergic Pathway in Regulating Dynamic Metabolic Interactions across Cell Types-Tumour Microenvironment and Metabolism. Int J Mol Sci 2020; 22:E141. [PMID: 33375613 PMCID: PMC7795031 DOI: 10.3390/ijms22010141] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 12/21/2020] [Accepted: 12/22/2020] [Indexed: 02/07/2023] Open
Abstract
This article reviews the dynamic interactions of the tumour microenvironment, highlighting the roles of acetyl-CoA and melatonergic pathway regulation in determining the interactions between oxidative phosphorylation (OXPHOS) and glycolysis across the array of cells forming the tumour microenvironment. Many of the factors associated with tumour progression and immune resistance, such as yin yang (YY)1 and glycogen synthase kinase (GSK)3β, regulate acetyl-CoA and the melatonergic pathway, thereby having significant impacts on the dynamic interactions of the different types of cells present in the tumour microenvironment. The association of the aryl hydrocarbon receptor (AhR) with immune suppression in the tumour microenvironment may be mediated by the AhR-induced cytochrome P450 (CYP)1b1-driven 'backward' conversion of melatonin to its immediate precursor N-acetylserotonin (NAS). NAS within tumours and released from tumour microenvironment cells activates the brain-derived neurotrophic factor (BDNF) receptor, TrkB, thereby increasing the survival and proliferation of cancer stem-like cells. Acetyl-CoA is a crucial co-substrate for initiation of the melatonergic pathway, as well as co-ordinating the interactions of OXPHOS and glycolysis in all cells of the tumour microenvironment. This provides a model of the tumour microenvironment that emphasises the roles of acetyl-CoA and the melatonergic pathway in shaping the dynamic intercellular metabolic interactions of the various cells within the tumour microenvironment. The potentiation of YY1 and GSK3β by O-GlcNAcylation will drive changes in metabolism in tumours and tumour microenvironment cells in association with their regulation of the melatonergic pathway. The emphasis on metabolic interactions across cell types in the tumour microenvironment provides novel future research and treatment directions.

Comput Struct Biotechnol J 2020; 18:3507-3517.

Abstract
It is estimated that the rate of epigenetic changes may be orders of magnitude higher than that of genetic changes and that purely epigenetic mechanisms may explain why cancers arise with few or no recurrent mutations. However, supporting evidence remains limited, partly due to the cost of experimentally studying genome-wide epigenetic dysregulation. Since genome modification enzymes are recruited by long noncoding RNAs (lncRNAs) to specific genomic sites, analyzing differentially expressed genes and differentially methylated regions (DMRs) at the DNA binding sites of differentially expressed lncRNAs is important for uncovering epigenetic dysregulation. We performed RNA-seq and MeDIP-seq on a set of colorectal cancer (CRC) and normal colon samples and developed an analysis pipeline for combined analyses of gene expression, DNA methylation, and lncRNA/DNA binding. The genes identified in our data and important for CRC agree with widely reported findings. We found that aberrantly transcribed noncoding transcripts may epigenetically dysregulate genes, that correlated gene expression is significantly determined by epigenetic dysregulation, that differentially expressed noncoding transcripts and their epigenetic targets form distinct modules in different cancer cells, and that many hub lncRNAs in these modules are primate-specific. These results suggest that lncRNA-mediated epigenetic dysregulation greatly determines aberrant gene expression and that epigenetic dysregulation is highly species-specific. The analysis pipeline can effectively unveil cancer- and cell-specific modules of epigenetic dysregulation, and such modules may provide novel clues for identifying diagnostic, therapeutic, and prognostic targets for epigenetic dysregulation.

Abstract
GNB2L1 and its O-GlcNAcylation has been reported to play roles in gastric cancer metastasis. However, the roles of GNB2L1 in chemoresistance of gastric cancer has never been determined. In the present study, we found that GNB2L1 was downregulated in chemoresistant patients of gastric cancer, and observed the decrease of GNB2L1 in protein levels instead of mRNA levels in different chemoresistant gastric cancer cell lines. Further we proved that this downregulation of GNB2L1 was resulted from its elevated O-GlcNAcylation catalyzed by OGT in both cell lines and patients. Next, we investigate the function of GNB2L1 and its O-GlcNAcylation on gastric cancer metastasis during chemoresistance, and confirmed Ser124 as the major O-GlcNAcylation site on GNB2L1 that regulated its function on metastasis. Furthermore, our data demonstrated that GNB2L1 modulated EMT via regulating the translation of EMT-related proteins in the process of chemoresistance. In summary, this study indicated that GNB2L1 and its O-GlcNAcylation regulated metastasis via modulating the translation of EMT-related proteins in the chemoresistance of gastric cancer.
